Proximate Analysis, Minerals and Calories (click here for Midwest Lab report )

The table below indicates the values for test results from Midwest Labs, plus calculated values for components in a formula mixed at a ratio of 1:2 with water using WildAgain's nutrition calculator. The Kcals are calculated using both the standard Atwater calculation as well as the modified Atwater as prescribed by AAFCO.

Calcium % 1.61 Calcium % .29
Phosphorus % 1.01 Phosphorus % .18
Magnesium % .098 Ca/P Ratio 1.59
Sodium % .25 Kcals/cc (Atwater) .82
Potassium % .86 Kcals/cc (AAFCO) .75
Peroxide Value (what's this?) (Test not performed)

Ingredients (what's this?)

The table below indicates the primary ingredients for the lot number indicated. The ingredient "Latose" indicated below is identical to how it is presented on the label, though it is suspected to be a typographical error for the spelling of "Lactose". Except that Lactose is also listed further as an ingredient in the mix of added minerals and supplements(?).

Primary ingredients

Dried Milk Protein, Vegetable Oils, Dried Whey Protein Concentrate, Casein, Dried Skimmed Milk, Dried Corn Syrup Solids, Latose

Secondary ingredients Dicalcium Phosphate, Calcium Carbonate, Potassium Chloride, Mono and Diglycerides, Dipotassium Phosphate, Magnesium Sulfate, Lactose, L-Arginine, DL,Methionine, Taurine, Sodium Chloride, Choline Chloride, Vitamin E Supplement, Vitamin A Supplement, Vitamin D-3 Supplement, Zinc Sulfate, Ferrous Sulfate, Riboflavin Supplement, Calcium Pantothenate, Niacin Supplement, Manganese Sulfate, Copper Sulfate, Vitamin B-12 Supplement, Thiamine Hydrochloride, Pyridoxine Hydrochloride, Folic Acid, Calcium Iodate, Biotin, Sodium Selenite, Natural and Artificial Flavors Added.

 

Solubility Test (what's this?)

This product showed some degree of insolubility when used as an instant mix with both temperatures of water. A frothy layer of unwetted powder formed at the top of the cylinder at the line markers indicated. However, reconstitution improved somewhat when the product was allowed to rest for 4 hours, especially when the hotter water was used.

Figure 1. Hotter water and longer rehydration time generally improved the reconstitution of this product. Figure 2. The consistency and flowability of the residue also improved with the hotter water temperatures and longer hydration time.

 

Physical characteristics

The texture of this product was even and consistent. This resulted in very low measurement error described below. (The expected error shown below is equal to 1 standard deviation (statistically 68% of all measurements should fall within this range)).

Texture

Weight/TBSP and measurement variability

Weight (average) 6.4 grams / TBSP (large end of red scoop).
Texture and handling comments Smooth and very fine  in texture, scoops evenly and consistently.
Observed measurement variability (what's this?) Scooping error generally within +/- 1.3%.

Low error -2.3%; High error +3.9%.

Scoop or weigh? Scooping this product will likely result in an accurate volume, but weighing will produce a more accurate measurement.
