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.
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 ...
Another method for dealing with pricing based on protein and fat, is using energy-corrected milk (ECM), which adds a factor to normalize assuming certain amounts of fat and protein in a final milk product; that formula is (0.327 x milk mass) + (12.95 x fat mass) + (7.2 x protein mass). [11]
The two major defects associated with the Gerber method include: Charring – is observed as tiny black specs at the fat/non-fat interface in the butyrometer. This problem is due to charring of the milk proteins by the concentrated Gerber acid. It could also arise as a result of pouring the milk sample directly onto the acid in the butyrometer.
Enzyme assays can be split into two groups according to their sampling method: continuous assays, where the assay gives a continuous reading of activity, and discontinuous assays, where samples are taken, the reaction stopped and then the concentration of substrates/products determined. Temperature-controlled cuvette holder in a spectrophotometer.
Of that weight, 2% milk holds 5 grams of fat and whole milk contains 8 grams. So whole milk isn't much fattier than 2%. In fact, a gallon of 2% has more than half the fat as a gallon of whole milk.
This includes casein, caseinates, whey products (including whey butter and whey cream), cultured milk products (including yogurt, sour cream and cultured buttermilk), ultrafiltered milk, milk protein concentrate, milk serum proteins and fats. [1] [2] [3] Since the products vary considerably in composition, there is also a large variation in ...
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 ...
