POWDERS CONTAINING A BUFFER SALT AND AN AMINO ACID, RECONSTITUTION OF SUCH A POWDER INTO A NUTRITIONAL PRODUCT, AND METHODS OF USING SUCH A NUTRITIONAL PRODUCT

摘要

A powder contains a buffer salt and an amino acid, for example one or both of (i) least one glycine or functional derivative thereof or (ii) at least one N-acetylcysteine, L-cysteine or functional derivative thereof. Optionally the powder additionally includes at least one vitamin or mineral. Preferably the powder has at least one characteristic selected from the group consisting of (i) the amino acid is present in an amount that at least partially comprises the amino acid in a form selected from the group consisting of free form, dipeptides, tripeptides and mixtures thereof and (ii) the powder is substantially free of enzymes and antibodies. The powder can be reconstituted in a liquid containing an acidic component, such as juice or a polyphenol, and/or a protein, such as milk protein, plant protein, collagen or blends thereof. The buffer salt can minimize or prevent denaturation of protein and/or coagulation of protein upon reconstitution of the powder in the liquid.
