Powdered shelf life improver for food and method for producing the same

摘要

PROBLEM TO BE SOLVED: To provide a method of efficiently producing a powdery storable duration improver for a food product which has less influence to taste of a food product and sufficient storable duration improving effect, and suppresses the deviation in a content of acetic acid due to a segregation phenomenon.SOLUTION: A production method of a powdery storable duration improver for a food product comprises the steps of: (A) heating sodium acetate, an acetic acid solution and sucrose fatty acid ester, until the product temperature reaches 70 to 100°C, while agitating or mixing them, thereby obtaining a mixture; (B) cooling the mixture obtained by the step (A), until the product temperature reaches 10 to 40°C, while agitating or mixing the mixture, thereby obtaining a solidified product; and (C) crushing the solidified product obtained by the step (B).
