以不同新鲜度的太平洋刀鱼为原料制备去皮鱼片，在−20和−40C下贮藏12个月，研究脂肪氧化对鱼片品质劣变的影响。过氧化值和4-羟基-2-己烯含量随贮藏温度(−40 <； −20℃)的升高而增加，并与新鲜度相对应。与生的太平洋秋刀鱼相比，冷冻解冻的去皮太平洋秋刀鱼的过氧化值和4-羟基-2-己烯含量显著增加；维生素E仅减少了3个月。抗氧化剂处理的去皮鱼片在−20C下保存12个月，浸泡在0.8%维生素E中或用吸氧器包装，可抑制脂肪氧化。4-羟基-2-己烯醛的含量与丙醛密切相关，丙醛是脂肪氧化的一种分解产物，产生鱼腥味。本研究介绍了太平洋刀鱼高质量无皮鱼片的加工工艺，并对冷藏12个月的无皮鱼片的脂肪氧化水平进行了评估。本研究的结果将有助于防止去皮鱼片等鱼类产品的脂肪氧化，并提高太平洋秋刀鱼等高脂肪鱼类的去皮鱼片的质量。
ABSTRACTSkinless fillets were prepared from Pacific sauryCololabis sairaof varying degrees of freshness and then stored at −20 and −40C for 12 months to investigate the effects of lipid oxidation on quality deterioration. Peroxide value and 4‐hydroxy‐2‐hexenal levels increased with storage temperature (−40 < −20C) and corresponded with freshness. Peroxide value and 4‐hydroxy‐2‐hexenal levels increased remarkably in frozen‐thawed Pacific saury skinless fillets in comparison with raw Pacific saury; vitamin E was reduced for only 3 months. Lipid oxidation was inhibited when antioxitant‐treated skinless fillets were stored at −20C for 12 months, immersed in 0.8% vitamin E or packed with an oxygen absorber. The 4‐hydroxy‐2‐hexenal content was strongly correlated with propanal, a decomposition product of lipid oxidation that yields a fishy odor.PRACTICAL APPLICATIONSThis study introduces processing techniques for high quality of skinless fillets from Pacific saury and evaluates the lipid oxidation levels of skinless fillets stored in freezer for 12 months. Results of this study will contribute to prevent fish product such as skinless fillets from lipid oxidation and to improve the quality of skinless fillets from fatty fish such as the Pacific saury.
