HOT WATER EXTRACT OF MUSHROOM FRUIT BODY

摘要

PROBLEM TO BE SOLVED: To provide a food material derived from a mushroom belonging to the genus Lyophyllum, easily chewed and swallowed even by aged persons who have reduced physiological functions such as manducation, swallowing while leaving characteristic taste of the mushroom.

SOLUTION: The hot water extract obtained by hot water extraction of the Lyophyllum mushroom fruit body without subjecting to a defatting treatment, forms gel with ≥1x103Pa of rupture stress by left-standing 24 hours at 4°C. The hot water extract of the Lyophylum mushroom fruit body is obtained by eliminating fractions of ≤10,000 molecular weight from the hot water extract, and the dried product obtained by heating the hot water extract at a temperature ≤60°C exhibits following physico-chemical properties. The product is a white to yellowish white powder, comprising 40-70% of sugar contents, 1-20% of proteins and 10-40% of lipids, soluble in water, and 1% solution of the same forms gel with ≥1x103Pa of rupture stress.
