Versuchsvorschrift

Japanese chestnuts, which had been pealed their astringent skins, were soaked in a 50% aqueous trehalose solution containing 0.1% citric acid at 60° C. overnight, and then taken out of the solution, soaked in a solution, which had been prepared by dissolving in 25 parts by weight of water 0.08 part by weight of citric acid, 80 parts by weight of “TREHAOSE®”, a high-purity crystalline trehalose hydrate commercialized by Hayashibara Shoji, Inc., Okayama, Japan, and had been boiling at about 106° C. under normal atmospheric pressure, and continued boiling for about 20 min to dehydrate and concentrate the Japanese chestnuts until the solution was heated to about 112° C. Thereafter, the fried Japanese chestnuts were placed on a plain sieve and ventilated with air heated to 35° C. overnight for drying to obtain a non-fried fresh Japanese chestnut coated with crystalline trehalose dihydrate by crystallizing the saccharide thereon.
