Soybeans were washed with water and soaked in 4-time volumes of water for six hours, and then boiled and placed on a sieve to obtain boiled beans. The beans were soaked in a 60% aqueous trehalose solution containing 0.1% magnesium chloride at 70° C. for three hours, and taken out of the solution. Five parts by weight of the resulting beans were soaked in a solution, which had been prepared by dissolving in 35 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 115° C. under normal atmospheric pressure, and continued boiling for about 10 min to dehydrate and concentrate the soybeans until the solution was heated to about 118° C. Thereafter, the fried beans were placed on a plain sieve, sprayed with a small amount of a high-purity trehalose hydrate, and ventilated for five hours with air heated to 35° C. to obtain a non-fried fresh tea leaf coated with crystalline trehalose dihydrate by crystallizing the saccharide thereon.
