Keeping your protein powder fresh for as long as possible reduces the need to ask, "Should I or shouldn't I eat 'expired' protein powder?" Rule No. 1: Store protein powder in a cool, dark and dry ...
It’s understandable to think of whey and protein powder as one and the same but that’s not exactly true: Whey protein is actually the liquid that comes from adding enzymes to milk during ...
7. Eggs. Expired eggs risk being contaminated with Salmonella both on the shell and inside the egg, which can make you sick. If you're wondering whether those eggs in the fridge are still safe to ...
This type of whey does not contain glycomacropeptide, which is formed only after the addition of rennet. [14] [15] [16] There is evidence that whey protein is more bio-available than casein or soy protein. [17] [18] Whey protein is commonly marketed as a dietary supplement, typically sold in powdered form for mixing into beverages. [19]
Glycomacropeptide (GMP) is a glycosylated peptide formed during renneting as a fragment of sweet whey. Acid whey from yogurt or curdling cheese without the use of rennet does not contain GMP. The unglycosylated form is known as caseinomacropeptide or CMP. Both forms exist in roughly similar amounts in whey.
The major protein in whey is β-lactoglobulin, followed by α-lactalbumin (β-lactoglobulin ≈ 65%, α-lactalbumin ≈ 25%, serum albumin ≈ 8%, other ≈ 2%). β-lactoglobulin is a lipocalin protein, and can bind many hydrophobic molecules, suggesting a role in their transport. β-lactoglobulin has also been shown to be able to bind iron via siderophores [7 ...
Sell-By dates—just how important are they? Are they the same as expiration dates? Many people toss food when the Sell-By date has passed, but could you be wasting perfectly good food? Experts ...
The study found that whey protein hydrolysate led to better nitrogen retention and growth than the other proteins studied. However the study's flaw is in the BV method used, as starvation affects how well the body will store incoming protein (as does a very high caloric intake), leading to falsely elevated BV measures.
