PROBLEM TO BE SOLVED: To provide a food product durability improvement agent capable of improving the physical changes in yield, discoloration and elasticity not only before heating but also after heating without exerting influence on the taste of a food product.SOLUTION: Provided is a food product durability improvement agent containing sodium acetate, calcium acetate and coated organic acid, in which the ratio of the calcium acerate is 5 to 140 pts.wt. to 100 pts.wt. of the sodium acetate. The coated organic acid is fumaric acid coated with hardened oil, and the ratio of the fumaric acid to the coated fumaric acid is 30 to 70 wt.%.SELECTED DRAWING: NoneCOPYRIGHT: (C)2016,JPO&INPIT【課題】食品の味質に影響を与えずに、加熱前のみならず、加熱後の歩留まり、変色、弾力などの物性変化を改善し得る食品用日持ち向上剤の提供。【解決手段】酢酸ナトリウム、酢酸カルシウムおよび被覆有機酸を含有し、酢酸カルシウムの割合が酢酸ナトリウム100重量部に対し5~140重量部である食品用日持ち向上剤。被覆有機酸が、硬化油で被覆されたフマル酸であり、被覆フマル酸に対するフマル酸の割合が30~70重量%である該日持ち向上剤。【選択図】なし
