The Japanese millet protein constituent null which possesses the rise function of HDL cholesterol concentration in

摘要

PROBLEM TO BE SOLVED: To obtain a protein composition derived from barnyard grass, having a function of increasing plasma HDL-cholesterol level, and a function of decreasing arteriosclerotic index by adding water to powdery barnyard grass followed by heating to gelatinize the heated mixture then adjusting it to pH 6, adding α-amylase to the pH-adjusted product to carry out reaction, subjecting the reaction product to centrifugation to collect the precipitate, freeze-drying the collected precipitate to remove fat therefrom and thereafter washing the nonfat fraction followed by air-drying the thus washed product. SOLUTION: These protein and protein concentrate are advantageously applicable as foods (including drinks), food additives, and prophylactic and/or therapeutic agents for hyperlipemia, each having prophylactic effect on hyperlipemia and/or arteriosclecrosis.
