Influence of High-Pressure Processing on Foxtail Millet Protein Concentrate (FMPC) and its Characteristics

The pre-treated Foxtail millet were collected with milk sample to obtain a FMPC by biochemical extraction process. The optimized milk ratio for the testing prepared sample was done with the ratio of the1:2 (Foxtail millet: Distilled water). The effect of HPP (High Pressure Processing) treatment for the millet milk was optimized at 550 MPa for 5 minutes to improve the yield of FMPC as well as improvement in Total Phenolic Content 1403.51 mg GAE/ g, dry weight for the prepared FMPC. The freeze-dried FMPC in dry powder was obtained with the optimized time period of 24 hours at -40℃. The prepared FPMC was characterized with FTIR analysis and compared with commercial protein powder. Further analysis of proximate studies revealed that the FMPC contains a higher amount of Protein content with ranging from 13-17% for the utility towards the commercial application as millet protein supplement in food products.
