Challenges in the Manufacturing of Autoclaved Pet Food

By Ludmila Barbi T. Bomcompagni

In this context, autoclaves emerge as a promising technology for producing natural, secure, and long-shelf-life food without the use of artificial preservatives. This article explores the potential of autoclaves in the pet food industry in LATAM, addressing the technical aspects of the process, types of packaging, challenges in the formulation of natural products, investments, and logistic or commercial opportunities.   What Is an Autoclave?   It is a thermal sterilization process widely used in the feed, pharmaceutical, and medical industries. For the pet food industry, it lets them make natural, wet food that is highly microbiologically safe without artificial preservatives.
  The process involves the high-temperature treatment of packaged food using autoclave equipment —between 115 °C and 130 °C— and pressure for a certain period. This thermal process eliminates microorganisms, pathogens, and sources of decomposition ensuring product stability for months, even at room temperature.
  Compared to extrusion (for dry food), the autoclave preserves sensorial and nutritional characteristics like fresh food. This is a valued aspect in the natural product segment, where people seek simple formulas, recognizable ingredients, and minimum industrial interference. Moreover, autoclaves are compatible with different packaging, widening design possibilities and product positioning in the market.   Types of Packaging   When processing sterilized food in autoclaves, packaging selection is essential, particularly for natural pet food. The packaging must withstand high temperatures and pressures in the sterilization process while protecting the sensorial and nutritional characteristics of food. 
  The most used formats include: Flexible packaging: they are light, easy to store, and offer a good barrier against oxygen and moisture. They enable modern and practical presentation, valued by urban consumers.
  Metal cans: commonly used for wet food, they provide excellent thermal resistance and a long shelf life. However, they are heavy and have a major environmental impact, depending on the local recycling system. 
  Thermoformed trays (with sealed caps): they combine rigidity and practicality. Thermoformed trays are deal for individual portions. It can be made of recyclable or biodegradable materials to align with the 'natural' and sustainable proposal. The material must be compatible with the autoclave as well as costs, visual appeal, sustainability, and logistics. Packaging with intelligent barriers, such as multi-layer films or steam release valves, is gaining ground in the sector.    Challenges in Formulation of Natural Products   Formulating natural pet food sterilized in autoclaves faces technical and regulatory challenges since it is difficult to add additives. 'Natural' appeal requires clean labels, recognizable ingredients, and minimum chemical interference, which limit the use of preservatives, stabilizers, and palatants —commonly used in traditional products.
  During the thermal process, one of the main obstacles is ingredient stability. Besides being efficient in sterilization, the autoclave can degrade sensitive compounds, such as vitamins, natural antioxidants, and certain amino acids. So then, it requires careful selection of raw material and, in most cases, supplementation.
  On the other hand, the absence of artificial preservatives improves the importance of controlling pH, water activity (aw), and microbiological quality. Strategies, such as the use of plant extracts with antimicrobial properties (e.g., rosemary, green tea), functional fibers, and essential oils have been explored as natural alternatives. Natural zeolite, a microporous mineral with high absorption capacity, has gained importance. Its use reduces free moisture, enhances microbiological stability, and reduces fecal odors. It is also thermal stable, which makes it compatible with the autoclave process. However, zeolite must be carefully evaluated according to local regulations, its type and purity, and consumer perception, mostly in products with high natural appeal. 
  In other words, formulation must balance naturality, stability, and palatability while meeting the limits imposed by law and market expectations.   Investments and Infrastructure   Implementing a natural, sterilized food production chain in autoclave requires careful planning and specific investment, especially for companies that aim to join this niche with differentiation and quality.
  An industrial autoclave is the principal equipment. It can vary on capacity, automation levels, and operation (per batch or continuous). In addition, aseptic packaging systems, thermal sealing, temperature and pressure control are essential, as well as rigorous microbiological management. 
  Other investments are:
  Commercial kitchen design to prepare and homogenize formulas. Packaging equipment is compatible with the selected formats (bags, cans, and trays). Traceability and quality control systems are essential to ensure food security and regulatory compliance. Training technical staff in Good Manufacturing Practices (GMP) and thermal control.
  The initial cost can be high, but there are some alternatives, such as production externality (co-manufacturing) that allows trying the market with fewer risks. Another possibility is the gradual adoption of technology, beginning with small batches and improving it according to demand. Companies investing in this model are gaining added value and logistics flexibility since autoclave products are stable at room temperature by removing the need for a cold chain, which reduces distribution costs and widens the geographic reach.   Logistics and Distribution   Another advantage of these autoclave products is the stability at room temperature, which significantly eases logistics and reduces cooling and conveying costs. It allows them to be distributed to far regions or with limited infrastructure, widening commercial reach, especially in LATAM countries with geographic diversity.
  Moreover, its long shelf-life —between 12 and 24 months— facilitates inventory planning and entering sales channels, such as specialty retailing, E-commerce, and exportation. Sterilized products in autoclaves can be stored at conventional distribution centers, representing a competitive advantage against dairy and frozen foods.
  It is important to consider packaging weight and volume since it influences the cost per unit conveyed. Flexible packaging (bags) is more advantageous than cans or strong trays.
  Educating the consumer is also relevant. Since many pet owners still relate natural food with cooling, it is crucial to transmit that the product is safe and stable, even outside the cooler, because of the sterilization process in the autoclave.   Conclusion   To produce natural pet food, sterilization in the autoclave is a robust, versatile technological solution combining microbiological security, logistics practicality, and commercial appeal. Although it faces technical challenges, mostly in formulation and packaging selection, it offers big opportunities for innovation and differentiation in the LATAM market. 
  Having this technology, combined with clear communication and sustainable positioning, paves the way for new markets and helps brands consolidate as benchmarks of natural, quality pet nutrition.

Beyond Kibble and Cans: The Rise of Innovative Pet Food Technologies

By Juan Gómez Basauri, Ph.D.

Today, a new wave of technologies —ranging from freeze-drying and air-drying to high-pressure thermal pasteurization (HPTP), 3D printing, and fluid bed drying— is reshaping the production landscape. These innovations enable enhanced nutrient retention, food safety, customization, and alignment with evolving consumer values.
  This article explores and briefly describes these emerging processing technologies and the underlying drivers pushing the pet food industry beyond its traditional boundaries.   Traditional Processing Methods: The Cornerstones   Extrusion (Dry Kibble)
The most common method, extrusion, involves cooking a dough mixture (typically proteins, grains, and functional additives) under high heat and pressure. This produces shelf-stable, uniform kibbles efficiently and at scale. However, the intense thermal process can degrade heat-sensitive nutrients like thiamin and riboflavin and limit format customization.
  Retort Sterilization (Canned Food)
Used for wet foods, this method involves sealing ingredients in cans or pouches and sterilizing them at high temperatures (≥121oC). It ensures microbial safety and extended shelf life but can negatively affect texture, palatability, and nutrient bioavailability.

While effective, both methods face challenges in meeting the rising demand for transparency, nutrient integrity, and personalization.   Innovative Petfood Processing Technologies   Freeze-Drying This method removes moisture via sublimation under vacuum at low temperatures, preserving texture, flavor, and heat-sensitive nutrients. While ideal for raw diets, freeze-drying is capital-intensive and poses risks of post-process contamination without additional safety interventions.
  Air-Drying and Dehydration It involves drying foods at moderate temperatures (60–90°C) to produce chewy, jerky-like products. It supports nutrient retention better than extrusion but requires strict moisture control to prevent microbial growth.
  Cold Extrusion A non-thermal technique for forming doughs into patties or treats. Cold extrusion is well-suited for incorporating probiotics, enzymes, and other heat-sensitive actives but requires refrigeration or secondary processing to ensure shelf stability.
  Sous Vide (Gently Cooked) Slow cooking in vacuum-sealed pouches in a water bath at precise low temperatures retains freshness and nutrient integrity. This method appeals to the humanization trend but demands cold-chain logistics and has a shorter shelf life than dry products.
  High Pressure Processing (HPP) HPP inactivates pathogens in packaged food using high pressure (400–600 MPa) without heat, preserving raw-like textures and nutrients. Though effective and clean-label friendly, it involves high costs and limited throughput due to batch processing.
  High Pressure Thermal Pasteurization (HPTP) HPTP combines high pressure with mild heat (70–90°C) to enhance microbial inactivation, including spores. It bridges the gap between raw nutrition and safety, making it a promising option for fresh-style diets. However, it requires careful control to avoid nutrient loss or product degradation.
  3D Printing Still, in the early stages of commercial application, 3D printing enables the layering of custom pastes into specific shapes, dosages, or nutrient profiles. It opens doors for hyper-personalized nutrition, functional layering, and portion-controlled diets, though production speeds remain a constraint.
  Fluid Bed Drying This precision drying method uses hot air to suspend and gently dry product particles in a fluidized state. It's ideal for preserving volatile nutrients and coating small kibbles or treats with functional additives or palatants. Although energy-efficient and precise, it carries higher capital costs.   Why the Shift Toward New Technologies?   Humanization and Premiumization Modern pet parents expect their furry animals' food to mirror their own —clean-label, fresh, recognizable, and natural food. This cultural shift is pushing brands to adopt more transparent and minimally processed formats.
  Functional Nutrition Pet parents increasingly seek diets that support joint health, gut microbiota, immunity, skin, and coat condition. Many bioactives (e.g., omega-3s, vitamins, probiotics) are heat-sensitive and degrade during traditional processing, making gentle technologies more suitable.
  Ingredient Transparency Consumers want to 'see the real food.' Technologies like freeze-drying and sous vide better preserve the visual integrity of meats, vegetables, and superfoods, creating more trust in the product.   Food Safety: Evolving Risks and Responsibilities   Emerging technologies also introduce new safety considerations:
  Non-thermal processes (e.g., freeze-drying, cold extrusion) do not eliminate pathogens unless paired with validated interventions like HPP/HPTP.
  Water activity and shelf stability must be validated rigorously, especially in semi-moist or high-moisture products.
  As fresh, raw, or gently processed foods grow in popularity, regulatory scrutiny will intensify. In the U.S.A., the Food and Drug Administration (FDA) regulates pet food similar to that for other animal foods. 
  Manufacturers must implement robust hazard analysis, kill-step validation, and post-process contamination controls to ensure food safety and compliance.   Final Considerations   The evolution of pet food processing is being driven by intersecting trends in consumer demand, food science, and technology innovation. While extrusion and retort sterilization will remain essential for many mainstream applications, they may not be sufficient to serve the growing market for premium, functional, and transparent pet nutrition.
  Brands have the opportunity for strategic diversification—leveraging traditional methods for staple products while incorporating alternative formats to meet specific consumer demands and positioning themselves at the forefront of pet food innovation. The future will favor companies that combine scientific rigor, processing innovation, and a deep understanding of consumer insight to deliver differentiated value across diverse product formats.

The Hidden Costs of Metal Contamination in Pet Food Processing (And How to Prevent It)

While the dangers of metal fragments in food products are well known, the true financial consequences of contamination are not always apparent until it's too late. From massive product recalls and reputational damage to regulatory fines and equipment failure, the hidden costs of metal contamination can cripple a pet food business. Fortunately, there are proven, cost-effective solutions to mitigate these risks—magnetic separation being one of the most powerful.
  Let's explore the full scope of metal contamination in pet food processing, why it matters more than ever, and how preventive strategies can safeguard your operations and reputation in the long term.
  Why Metal Contamination Is a Major Issue in Pet Food Processing
Pet food manufacturers operate in highly regulated environments with strict standards for hygiene, ingredient integrity, and traceability. Even minor lapses in contamination control can have serious repercussions.
  Metal contamination typically occurs from three sources:
  Processing Equipment Wear and Tear: As machinery components degrade over time, they can release tiny metal shards into the product stream, often going unnoticed until damage or contamination is discovered further downstream.
  Raw Material Contamination: Ingredients may already be compromised before they enter your facility. If these materials are not adequately tested and filtered, they pose a direct contamination risk.
  Operator Error or Maintenance Failures: Human oversight and inadequate maintenance can contribute significantly to contamination events, especially when production is scaled or rushed to meet deadlines.
  In pet food production, metal contaminants are not only a physical hazard—they're also a financial and regulatory liability. Detection of even trace amounts of metal can trigger a cascade of consequences that reach far beyond the immediate scope of product loss.
  Additionally, the risk of contamination extends beyond just the batch in question. It can affect adjacent product lines, raise questions about facility-wide hygiene standards, and lead to extensive investigations that can shut down operations for days or weeks.
  The Hidden Costs of Contamination Incidents
Contamination incidents are far more than isolated quality control failures—they're events that can shake the foundation of a business. 
  Here's a breakdown of the most significant hidden costs:
  Product Recalls and Brand Damage
A recall not only incurs direct costs like logistics, product disposal, and communication efforts—it also significantly damages brand trust. In a crowded market, pet owners are highly sensitive to safety issues, and negative press can lead to permanent customer loss.
  The effects of a recall often ripple outward. Retailers may pull other products from shelves. Distributors may hesitate to place new orders. And consumer trust, once lost, is extremely difficult to rebuild. The long-term revenue losses from a single incident can exceed the immediate costs of recall logistics.
  Lawsuits and Liability Risks
Contaminated pet food can cause serious harm to animals, potentially resulting in legal action from pet owners. Lawsuits may lead to costly settlements and additional regulatory scrutiny. Beyond financial penalties, the damage to your company's public image can be immeasurable.
  Class action lawsuits, especially those amplified by media coverage, can linger for years. The legal fees alone can cripple smaller manufacturers, and settlements or judgments can force businesses to restructure or even shutter completely.
  Equipment Damage and Downtime
Undetected metal fragments can harm processing machinery, leading to expensive repairs, unplanned downtime, and lost productivity. In high-output environments, even a few hours offline can result in massive financial setbacks.
  Additionally, damaged machinery might not be caught immediately, which means ongoing inefficiencies, potential product quality issues, and cascading maintenance problems that compound over time. Predictive maintenance is critical, but so is source-level prevention.
  Regulatory Fines and Compliance Penalties
Government and industry regulators take contamination incidents seriously. Failing inspections or breaching compliance can result in fines, suspension of licenses, or mandatory facility upgrades.
  Compliance failures often lead to increased scrutiny, with agencies requiring regular audits, additional certifications, and costly infrastructure changes. In some markets, repeated non-compliance can even result in a ban on selling products.
  Together, these hidden costs can snowball, creating long-term financial stress that compromises competitiveness and sustainability.
  How Magnetic Separation Reduces Contamination Risks and Costs
Preventing contamination is always more cost-effective than managing the aftermath. One of the most efficient and scalable methods of protection is magnetic separation.
  Magnetic separators work by removing ferrous and work-hardened stainless steel particles from the product stream before they reach downstream equipment or packaging. These systems are designed to capture even the smallest metal contaminants, reducing the likelihood of product recalls and equipment failure.
  For pet food manufacturers, implementing magnetic separation offers several key benefits:
  Increased Product Purity: Fewer contaminants mean higher product quality and consistency. Compliance Assurance: Meet or exceed industry safety standards with minimal manual oversight. Operational Efficiency: Minimize unplanned downtime due to equipment damage or by utilizing self-cleaning or easy-clean magnet designs. Brand Protection: Proactively significantly reduce risks that could lead to recalls and customer backlash and complaints.
  Furthermore, advanced magnetic separation technology is now available with features such as automated cleaning, data logging for compliance, and customizable designs to fit unique processing lines. This adaptability makes it easier than ever to implement without sacrificing throughput.
  Best Practices for Contamination Prevention in Pet Food Processing
Beyond magnetic separation, pet food manufacturers should embrace a comprehensive contamination prevention strategy. Here are some best practices to consider:
  Supplier Quality Control: Partner with trusted suppliers who provide certification and regular testing for raw materials. Implement incoming goods inspection protocols to catch contaminants early.
  Routine Equipment Maintenance: Schedule regular inspections and servicing to prevent metal wear and fragment release. Include predictive maintenance tools to anticipate component failures.
  Employee Training: Educate staff on contamination risks and procedures to ensure consistent handling and processing. Regular refreshers can ensure that safety practices remain at the forefront of people's minds.
  Integrated Detection Systems: Use metal detectors and X-ray systems alongside magnetic separators for layered defense. Ensure these systems are calibrated and tested frequently.
  Audit and Review: Conduct regular audits of your contamination control systems and processes to identify gaps and improvements. Use data to refine and optimize protocols over time.
  Documentation and Traceability: Maintain detailed records of inspection, testing, and maintenance activities. Good documentation supports compliance and helps quickly identify root causes in the event of contamination.

Improving Product Purity in Meat Rendering and Pet Food Processing

Sources of Metal Contamination in Meat Rendering
In the meat rendering industry, the sources of metal contamination vary depending on the part of the process and type of product. The objective of a magnetic separator is to prevent an unacceptable amount of contamination generated in a milling process being transferred to the client to deal with.

For example, many ovine meal processors face a challenge with removing slow-release capsule springs from rendered meat, which get ground-up within the product. Having a magnetic separator to extract these fine metals is an excellent way to increase the quality controls and solve this issue.

A common source of contamination found in poultry processing are magnetic stones, which originate from the gut of the poultry and are ingested from the ground while feeding. The magnetic stones can be removed by utilising powerful magnetic separation equipment.

Another very common source of metal contamination in meat rendering is the hammer mill. As the hammer mill materials slowly wear away, these metal fragments (coarse and fines) are introduced into the product. Effectively extracting these fragments can only be done with a strategically positioned, high-intensity magnetic separator.

To reduce machine protection issues in the meat rendering industry, these types of magnetic contamination need to be removed from the process. Factors such as screen breakage, downtime, loss of production, and tramp iron contamination causing fires/explosions in the hammer mill can all be drastically reduced by placing correct metal fragment controls in place. This means less downgraded products, reduced quarantined shipments, prevention of brand name damage, and satisfied clients!

Many rendering industry professionals state that they were not aware of the levels of fine metal fragments within their meat and bone meal until installing a magnetic separator and seeing the vast amount of magnetic fines extracted. A great way to discover the levels of metal contamination in your finished meat meal is through utilising a certified Lab Test Magnet Probe. The magnetic probe is placed into the bag of finished meal and swirled around to collect magnetic fragments and provide an indication of the metal contamination levels.
Sources of Metal Contamination in Pet Food Processing
Predominantly, metal contamination comes from bulk ingredients and is then distributed throughout the product lines. The remainder of contamination is generated in the process and varies greatly depending on the type of impact machinery that is used for sizing and screening ingredients and the longevity and wear of conveying systems.

The objective of magnets in pet food is to control contamination on bulk intakes and to also act as a final control prior to packing areas and metal detection. Magnetic separators play a crucial role in retaining the magnetic fines contaminants that are below sensitivity threshold of metal detection before they reach the CCP. An efficient magnet will drastically reduce waste from metal detectors and improve product purity from magnetic fines contamination.
Magnetic Separation Solutions for Meat Rendering & Pet Food Processing:
  Mag-Ram® Automatic Self-Cleaning Magnet
The Mag-Ram® Automatic Self-Cleaning Magnet has proven to be one of the best performing and successful magnets as it can be programmed to automatically clean itself and therefore save operator time, as well as reduce safety risks. Typically installed at incoming dry materials locations (such as MBM or grain) and final dry product/bulk out-loading locations.
  Mag-Ram® Self-Cleaning Magnet in meat rendering
In some applications, the contamination is so high that manually cleaning conventional grate magnets is neither practical nor convenient. Once contamination builds up over the magnetic bars, the magnet's strength is 'cancelled out', meaning that further contaminants passing over the magnet just keep flowing down the product stream and remain in the finished product. 

The modular design of the Mag-Ram® allows it to handle anywhere between 3T to 90T per hour! This self-cleaning magnet can clean one ram at a time or all at once, and a wear equalization feature is incorporated to prevent flat spots on the magnet and uneven wear on the seals. This means more reliability for a longer period of time.

The Mag-Ram® magnetic bars/rams are engineered to rotate with each cleaning cycle, and short bursts of air are directed at the magnets also help remove the pyramid of excess material from being carried over to the reject side. This means a lean contaminant sample is achieved, easy to analyse for more accurate traceability of risks and less product wastage.
Spherical Inline Pneumatic Transfer Magnet
Where a gravity-feed magnet, such as the Mag-Ram®, is not feasible and the product is pneumatically conveyed via blow, vacuum, or pneumatic transfer line, a Spherical Inline Pneumatic Transfer Magnet is a very effective solution. These aerodynamic magnetic separators are very resilient in high-flow and abrasive applications and enable efficient extraction and retention of metal from high-velocity powder lines without experiencing bulk density problems.
  Spherical Inline Pneumatic Transfer Magnet
Dual Round Nose Plate Magnet
For difficult-to-flow applications with products such as cakes (or crax), or applications processing chicken frames, whole muscle products, poultry, beef, lamb, venison, etc, a Dual Round Nose Plate Magnet is an efficient solution. For pet food processing applications, these units can be installed prior to expensive processing machineries, such as grinders, shredders, dicers, and emulsifiers, to remove metal fragments to avoid costly damage, downtime for repair/maintenance, and loss of production. Dual Round Nose Plate Magnets easily pick up chunky contaminants such as nails and bolts from the product and protect machinery without an unacceptable restriction to the product flow.
  Dual Round Nose Plate Magnet in a rendering application
Rapidclean® Grate Magnet
The Rapidclean® Grate Magnet is an effective grate-in-housing system designed for dry ingredients such as meals and powders. With easy-cleaning operations conducted wholly outside of the product zone and the absence of stainless steel sleeves, the Rapidclean® is a hygienic alternative to conventional sleeved grate magnets and pull-through wiper-style magnets. Plant operators can also fully inspect magnet bars before they are returned to the product flow. 
  Contamination collected on Rapidclean® Bars
Emulsion & Slurry Pipeline Separator
For viscous meat emulsions, slurries, and liquids, from which it is often difficult to extract weakly magnetic fragments, a hydro-dynamic Emulsion & Slurry Pipeline Separator provides superior product-to-magnet contact and more efficient magnetic separation. 

The Emulsion & Pipeline Separator features powerful, high-intensity +11,000 gauss Acutex® Probe Magnets. These patented magnets intercept the flow of product and extract physical metal fragments including work hardened stainless steel (originating from equipment wear) and magnetic stone particles.
  Emulsion & Slurry Pipeline Separator installed in a pet food application
