摘要： PURPOSE:To provide a natural anti-oxidizing material which prevents the rancidity phenomenon of fats and oils contained in foods and the reduction of flavor during preservation, containing a hydrolyzate of a seed coat of guar as an active ingredient. CONSTITUTION:A seed coat of guar is treated with a mineral acid, an alkali hydroxide or an enzyme to hydrolyze the protein contained in the seed coat. The degree of hydrolysis is within the range of 20-50%. After hydrolysis, the pH of liquid is adjusted to 5.5-6.0. The liquid is filtered to remove impurities. An emulsifying agent such as propylene glycol fatty acid ester, glycerol fatty acid ester, sorbitan fatty acid ester is added to the filtrate in an amount of not more than 15% of the emulsifying agent based on the combined amount of amino acid, peptide and undecomposed protein contained in the filtrate to obtain a liquid product as such. Alternatively, the liquid product is freeze-dried or spray-dried to obtain a powder. When a powdered products is prepd. by adding a known anti-oxidizing material such as tocopherol, phytic acid to the liquid product, anti-oxidizing action can be increased by two or three times as compared with single use.
