The Dumas technique has been automated and instrumentalized, so that it is capable of rapidly measuring the crude protein concentration of food samples. This automatic Dumas technique has replaced the Kjeldahl method as the standard method of analysis for nutritional labelling of protein content of foods (except in high fat content foods where ...

This high-protein low-lactose ratio makes MPC an appealing ingredient for protein-fortified beverages and foods and low-carbohydrate foods. [2] MPC can make products more heat stable, and it can provide solubility and dispersibility when used. [2] This solubility makes MPCs beneficial in dairy-based mixes. [3] MPC is useful in foaming and whipping.
BUN is an indication of kidney health. The normal range is 2.1–7.1 mmol/L or 6–20 mg/dL. [1]The main causes of an increase in BUN are: high-protein diet, decrease in glomerular filtration rate (GFR) (suggestive of kidney failure), decrease in blood volume (hypovolemia), congestive heart failure, gastrointestinal hemorrhage, [5] fever, rapid cell destruction from infections, athletic ...
The units GDU and MCU are based on how fast one gram of the enzyme will digest gelatin or milk proteins, respectively. 1 GDU approximately equals 1.5 MCU. [ 2 ] An increased amount of substrate will increase the rate of reaction with enzymes, however once past a certain point, the rate of reaction will level out because the amount of active ...
BCA protein assay in a 96 well plate. The bicinchoninic acid assay (BCA assay), also known as the Smith assay, after its inventor, Paul K. Smith at the Pierce Chemical Company, [1] now part of Thermo Fisher Scientific, is a biochemical assay for determining the total concentration of protein in a solution (0.5 μg/mL to 1.5 mg/mL), similar to Lowry protein assay, Bradford protein assay or ...
It could also arise as a result of pouring the milk sample directly onto the acid in the butyrometer. To avoid charring, first, ensure the acid concentration is right. Secondly, while adding the milk sample, let it flow on the side of the butyrometer to avoid violent reaction when it drops on the surface of the acid.
In fact, a gallon of 2% has more than half the fat as a gallon of whole milk. The FDA requires whole milk to have at least 3.25$ fat by weight. But the amount of fat can range from 3.25$ to 5 ...
