Abstract
This study investigated the effects of alkaline solutions on the production and characteristics of mung bean proteins (MBPs). MBPs were prepared using alkaline solutions of NaOH, NaHCO3, and Na2CO3 and designated MPN, MPH, and MPC, respectively. The yield, protein recovery, and crude protein content of MBP were not significantly different at different alkali concentrations (0.01–0.1%). Although there was no significant difference in MBP yield between alkali types, protein recovery and crude protein content increased in the following order: MPN > MPC > MPH. The essential and branched-chain amino acid contents, molecular weight distribution, and ζ-potential did not differ between MBPs. Regarding MBP pH-dependent solubility, MPN solubility was lower at pH 6–8 than that of MPH and MPC. This pattern was commonly observed for other physical properties. Overall, MBP was prepared using NaHCO3, and Na2CO3 and its functional properties were better when Na2CO3 was used than when NaOH was used.
期刊介绍:
The FSB journal covers food chemistry and analysis for compositional and physiological activity changes, food hygiene and toxicology, food microbiology and biotechnology, and food engineering involved in during and after food processing through physical, chemical, and biological ways. Consumer perception and sensory evaluation on processed foods are accepted only when they are relevant to the laboratory research work. As a general rule, manuscripts dealing with analysis and efficacy of extracts from natural resources prior to the processing or without any related food processing may not be considered within the scope of the journal. The FSB journal does not deal with only local interest and a lack of significant scientific merit. The main scope of our journal is seeking for human health and wellness through constructive works and new findings in food science and biotechnology field.
