摘要:
采用溶剂萃取法提取南极磷虾中的油脂,以气相色谱-质谱联用技术(GC-MS)分析磷虾油中的脂肪酸组成,并采用Schaal烘箱法研究添加抗氧化剂对磷虾油氧化稳定性及货架期的影响。结果表明,采用Folch法提取南极磷虾冷冻干燥粉末,总脂肪得率为(21.08±0.52)%。通过GC-MS分析甲酯化磷虾油中的脂肪酸组成,共鉴定出23个组分,其中不饱和脂肪酸占总脂肪酸的63.895%,多不饱和脂肪酸占总脂肪酸的25.739%、占不饱和脂肪酸的 40.28%,油酸、二十碳五烯酸(EPA)、二十二碳六烯酸(DHA)是主要的不饱和脂肪酸,十四碳酸、十六碳酸是主要的饱和脂肪酸。在磷虾油储藏过程中添加抗氧化剂,可显著提高稳定性、延长货架期,0.015%维生素E与0.005%柠檬酸增效剂协同作用可延长货架期至12.21个月,抗氧化效果优于合成的抗氧化剂。
