What is the difference between HBV and LBV?
The biological value relates to how many amino acids are present in a protein. If a food is missing one or more of the indispensable amino acids, it has a low biological value (LBV) . ... If a food has all the indispensable amino acids, it has a high biological value (HBV).
What is LBV and HBV proteins?
(HBV) protein: protein that contains all ten essential amino acids . (LBV) protein: a protein that lacks one or more essential amino acids. complementation: combining LBV protein foods to form a HBV protein meal. Different foods contain different amounts of amino acids.

What foods are LBV?
Low biological value (LBV) proteins are missing one or more of the essential amino acids we need. They’re only found in plant sources e.g. peas, lentils, nuts, seeds and most beans , and in smaller amounts in vegetables like spinach and broccoli.
Why is gelatin low in biological value?
Answer: Gelatin is classified as an incomplete protein, that is, it is incapable of replacing or building new tissue and hence cannot support life. (Another good example of incomplete protein is the protein in corn.) The reason is that gelatin lacks or is low in some of the essential amino acids .
Is quinoa high biological value?

How does steaming prevent loss of vitamins in vegetables?
Water is the enemy when it comes to nutrient losses during cooking. That’s why steaming is one of the best methods to preserve easily damaged nutrients, such as vitamin C and many B vitamins. Since vegetables don’t come in contact with cooking water during steaming, more vitamins are retained .
