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.

Ingredients (what's this?)

The table below indicates the primary ingredients for the lot number indicated.

Primary ingredients

Vegetable oil (preserved with BHA, BHT, propyl gallate and citric acid), dried skimmed milk, casein, egg yolk.

Secondary ingredients DL-Methionine, calcium carbonate precipitated, potassium phosphate monobasic, lecithin, dried corn syrup, calcium hydroxide, salt, monocalcium phosphate, sodium hydroxide, choline chloride, potassium chloride, silicon dioxide, magnesium carbonate, taurine, magnesium sulfate, vitamin A supplement, zinc sulfate, vitamin E supplement, ferrous sulfate, niacin supplement, copper sulfate, calcium pantothenate, vitamin B-12 supplement, manganese sulfate, vitamin D-3 supplement, folic acid, riboflavin, thiamine mononitrate, calcium iodate, pyridoxine hydrochloride.

 

Solubility Test (what's this?)

This product did not perform well as an instant mix, with noticeable unwetted powder forming a tight seal at the top of the cylinders. However, when the product was mixed and allowed to rehydrate for 4 hours, complete reconstitution was apparent.

Figure 1. Complete hydration after 4 hours. Figure 2. Less residue observed after 4 hours, with fluid of a very creamy consistency.

 

Physical characteristics

The texture of this product was uneven and inconsistent. This resulted in 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) 6.1 grams / TBSP (large end of red scoop).
Texture and handling comments Somewhat clumpy in texture, scoops somewhat unevenly and inconsistently.
Observed measurement variability (what's this?) Scooping error generally within +/- 3.3%.

Low error -6.6%; High error +4.9%.

Scoop or weigh? Weighing this product (rather than scooping) will produce a more accurate measurement.
