Abstract
Summary A protein isolate was prepared from mung bean flour by extraction with 0.001 NNaOH, precipitation at pH4.5, neutralization of the dispersed precipitate to pH6.8–7.0, and subsequent freeze drying. the isolate's amino acid composition was determined and found to be similar to that of mung bean flour except for cystine which was destroyed during isolate preparation. the following properties of the protein isolate were investigated: nitrogen solubility, buffer capacity, foamability, gelation. Except for buffer capacity, the isolate demonstrated good functional abilities in simple systems under laboratory conditions.
