中文摘要：为了获得不同渗透预处理试剂对罗非鱼热泵干燥综合品质的影响,以罗非鱼为实验材料,以干燥时间,Ca^(2+)-AT、Pase活性、复水率、白度、硬度及其综合评分作为指标,进行了罗非鱼经不同浓度的海藻糖、聚葡萄糖、茶多酚、甘露醇和谷氨酸钠浸渍预处理后的热泵干燥实验,获得不同浓度试剂预处理的热泵干燥曲线和品质变化规律。结果表明:5种添加剂的浸渍均能减少干燥时间,提升干燥品质。实验中最短的干燥时间比对照组减少了31%。品质综合评分较优的浓度分别为50 g/L海藻糖、20 g/L聚葡萄糖、6 g/L茶多酚、2 g/L甘露醇和2 g/L谷氨酸钠,且各自对应的综合评分与对照组相比分别提高了60.35%、60.25%、32.23%、41.63%和42.00%。

外文摘要：In order to obtain the effects of penetration reagents to the quality of heat pump drying tilapia fillets, different concentrations of trehalose, polydextrose, polyphenols, mannitol, sodium glutamate were studied and compared using the comprehensive scores of the Ca^2＋ -ATPase activity, rehydration ratio, whiteness and hardness as indicators. The curves of heat pump drying and the quality variation indicated that five additives all could reduce the drying time and improve the quality. The shortest drying time was reduced by 31% compared with the control group. The optimum concentration of trehalose, polydextrose, polyphenols, mannitol and sodium glutamate were 50 g/L, 20 g/L, 6 g/L, 2 g/L and 2 g/L. Furthermore, their corresponding comprehensive score improved 60.35% , 60.25% , 32.23% , 41.63% and 42.00% than that of the control group, respectively. The results could provide guidance in selecting penetration reagents for similar aquatic products drying.
