【摘要】 从几种常用的酸化剂中筛选的葡萄糖酸－δ内酯为较理想的热敏性食品用酸化剂，并且具有良好的扩散性，在ｐＨ３．０、３．７、４．２和５．３条件下，在不同的食品溶液中不会改变食品原有的口味。经测定，其有效扩散系数为５．０×１０－１０ｍ２／Ｓ。更多还原

【Abstract】 It was the purpose of this study to screen out an acidulant from some organic acids in the pH level of 3 0, 3 7, 4 2 and 5 3 and different kind of solutions The result shown that gluconic acid and its lactones would lower the pH without changing the original taste of the food Its effective diffusivity was 5 0×10 -10 m 2/s更多还原
