Reaction Steps

Ninety-five parts by weight of high-purity crystalline trehalose hydrate and 18 parts by weight of palatinit were placed in a dissolving tank, and admixed with and dissolved by heating in 63 parts by weight of water. The solution was placed in a concentrator, concentrated to boil down by heating to 125° C. under reduced pressure, continued concentrating by heating under reduced pressure while keeping the temperature until reaching to a moisture content of about 1.0%. Similarly as in Example A-1, the concentrate was subjected to an extruder for forming, cooled to ambient temperature to obtain a short-rod thermoplastic shaped-body of trehalose, about 2 mm in diameter and about 4 mm in length. Since the product was a colorless, transparent or translucent, and substantially amorphous shaped-body having thermoplasticity and satisfactory storage-stability under indoor circumstances, it can be arbitrarily reheated to a temperature of about 90° C. to about 160° C. to impart it free-flowing ability, then transformed or processed into a shaped-body with an appropriate form with or without using other substances having different functions. The product can be also used arbitrarily for preparing a paste containing trehalose by dissolving in a relatively-small amount of hot water, and the resulting paste can be used intact in an amorphous form or used as a powdered base after crystallization of trehalose.
