摘要: 选取功能性食品抗冻剂海藻糖和乳糖醇,并与传统商业抗冻剂混合,以得到“低甜、低热”且经济适用的复合抗冻剂。以白度、保水性、凝胶强度和盐溶性蛋白为指标,通过L9(34)正交试验探寻新的冷冻鱼糜复合抗冻剂配方。结果表明最佳配方为:海藻糖4%、乳糖醇3%、蔗糖1%、山梨醇2%,新的复合抗冻剂比商业抗冻剂甜度低,且能达到理想的抗冻效果。

Abstract: Functional food cryoprotectants such as trehalose and lactitol were selected to combine with traditional commercial cryoprotectants to prepare low-sweetness, low-calorie and economic composite cryoprotectants. Orthogonal tests were applied to explore the effects of composite cryoprotectant compositions on whiteness, water-holding capacity (WHC), gel strength and salt-soluble protein content. The results indicated the optimal formula of composite cryoprotectant was 4% trehalose, 1% sucrose, 2% sorbierite and 3% lactitol. The sweetness of new cryoprotectant was lower than that of commercial cryoprotectants, and revealed better cryoprotective effect.

Key words: silver carp, frozen surimi, low sweetness, cryoprotectant, gel strength, salt soluble protein
