黄鳍金枪鱼鱼皮热泵干燥特性研究

Study on heat pump drying characteristics of yellowfin tuna (Thunnus albacores) skin

摘要: 以黄鳍金枪鱼鱼皮为研究对象,采用热泵干燥技术,分别研究了热泵干燥温度和鱼皮干燥终点含水率对鱼皮复水率、胶原蛋白、蛋白质稳定性、脂肪氧化、色泽的影响。结果表明,热泵干燥温度为55℃,鱼皮干燥终点含水率为10%时,其色差变化、脂肪氧化程度最小,胶原蛋白含量与干燥前鱼皮最为接近,蛋白质热稳定性较好。

Abstract: Effects of heat pump drying temperature and terminal moisture content of fish skin on the characteristics of yellowfin tuna (Thunnus albacores) skin were studied, including the rehydration rate, collagen protein, protein stability, fat oxidation and color of the dried fish skin.Results showed that fish skin dried at 55℃ with the terminal moisture content of 10% displayed better color, lower lipid oxidation, higher collagen protein content and better protein stability.
