Process for the reversible transfer of thermal energy and heat transfer system useful therein

摘要

A method for coating foodstuffs such as crisp rice with alkaline metal salts of stearic acid and the coated foodstuff. The food may be coated by immersion or spraying of a stearate dispersed in a carrier fluid onto the food. On heating, the stearate forms a substantially continuous film over the food, which retains the crunchy texture of the coated food in the presence of moisture.
