Versuchsvorschrift

Five parts by weight of fresh leaves of green tea were soaked in a solution, which had been prepared by dissolving in 25 parts by weight of water about 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 leaves until the solution was heated to about 112° C. Thereafter, the fried leaves were placed on a plain sieve and allowed to stand at ambient temperature overnight to obtain a non-fried fresh tea leaf coated with crystalline trehalose dihydrate by crystallizing the saccharide thereon.
