SHELF-STABLE, CLEAR LIQUID NUTRITIONAL COMPOSITIONS COMPRISING EPIGALLOCATECHIN GALLATE (EGCG) AND METHODS FOR PREPARING THE SAME

摘要

Disclosed herein are shelf-stable, clear liquid nutritional compositions having a pH ranging from 2.5 to 4.6 and comprising water; at least one source of EGCg in an amount sufficient to provide 200-1700 mg/L of EGCg; and at least one source of protein in an amount sufficient to provide 25-45 g/L of total protein. The shelf-stable, clear liquid nutritional compositions lose no more than 20% by weight solids of the EGCg content present in the initial formulation of the compositions to epimerization, degradation, or both epimerization and degradation during heat sterilization. In certain embodiments, the loss of EGCg is exhibited by the amount of epimerization product GCg present in the shelf-stable, clear liquid nutritional composition following heat sterilization. Methods for preparing the shelf-stable, clear liquid nutritional compositions are also disclosed herein.
