PLASMA SPRAY DRYING FOR DOGS AND CATS

Plasma can effectively realize the coarse texture by the time that maintains the cohesion of the different diet ingredients. From the plasma spray drying process, a very fine powder is obtained that retains all the functional properties of the liquid product, such as the ability to produce a thermoplastic gel when diluted in water and subjected to high temperature or extreme pH, or its high retention of water and emulsification capacity, to name a few.

Due to these technological properties, plasma is used in products in chunks and treats as well as in cat food. The use of plasma not only contributes effectively to improving the piece texture but also maintaining all the different recipe ingredients.Plasma can effectively realize the coarse texture by the time that maintains the cohesion of the different diet ingredients.

Due to these technological properties, plasma is used in products in chunks and treats as well as in cat food. The use of plasma not only contributes effectively to improving the piece texture but also maintaining all the different recipe ingredients.

Image 1. Daily and total intake in cats for each diet used in the two palatability studies. Statistics were done by testing (iso product [1] or iso cost [2]) using the' t' test.

These differences in intake were also observed for the first choice of each diet, as shown in Table 1. Both studies conclude that there is a clear preference for diets containing plasma.

CATS PREFER RECIPES WITH PLASMA

We carry out different palatability studies with cats. The first study compared plasma with wheat gluten (WG) included at a rate of 20 g/kg (iso-product inclusion) in canned food. The second study analyzed plasma at a similar cost with 30g/kg WG in the recipe (inclusion of 10 g/kg for plasma). The ingredients and processing conditions were similar for all products obtained.

In the two tested recipes, there was a clear preference for palatability in the formula containing plasma (Image 1).

THE DOGS EXPERIENCED A GREATER ATTRACTION TO PLASMA FOODS

We fed 20 Beagles for two days in a test, preferably with standard diets with a control digest that contained 5% bovine fat and 1% flavoring or treatment containing the same digested with the addition of 2% of plasma coverage. As we can see in Image 2, the plasma-containing diet had an overall preference of 3.6:1 over the control diet (P < 0.0001), and the consumption ratio was 78:22. Plasma preference was similar on both days.

Plasma application provided the dogs with greater attraction to plasma-containing foods.

PLASMA IMPROVES FOOD PALATABILITY, INCREASING CONSUMPTION

In another study, commercially available dog foods were placed in water containing 0 or 20% plasma for 5min before air drying. 20 Beagles received two foods (control and with plasma) for a 2-day palatability test. As Image 3 shows, more dogs chose the coated treatments with plasma than control foods in all categories studied. Palatability and feed intake increased with the addition of plasma.
