| 中文摘要: |
| 以新鲜大黄鱼为原料，通过石油醚（沸程30~60 ℃）提取大黄鱼鱼油，并对大黄鱼鱼油的酸值、过氧化值、茴香胺值、共轭二烯值、脂肪酸组成、生育酚、胆固醇、角鲨烯、挥发性成分及磷脂组成进行测定。结果表明：大黄鱼鱼油得率为（31.25±3.66）%；大黄鱼鱼油酸值（KOH）为(0.59±005)mg/g，过氧化值为（5.50±0.76）mmol/kg，茴香胺值为0.30±0.06，共轭二烯值为22.32±109；大黄鱼鱼油中共检出17种脂肪酸，不饱和脂肪酸含量高达67.27%，其中油酸占（31.03±010）%、亚油酸占（12.21±0.07）%、DHA占（7.21±0.12）%、EPA占（4.48±0.03）%；大黄鱼鱼油中检出4种生育酚，主要是α-生育酚，含量为4.18 mg/100 g，β、γ、δ-生育酚含量均小于0.12 mg/100 g；大黄鱼鱼油中角鲨烯含量为40 mg/100 g，胆固醇含量为380 mg/100 g；大黄鱼鱼油中共鉴定出31种挥发性成分，主要包括醛、酮、醇、烷烃类；大黄鱼鱼油中磷脂含量较高的组分为PG（30∶ 0/16∶ 0）（19.61 mg/g）和PG（28∶ 0/16∶ 1）（10.87 mg/g）。 |
| 英文摘要: |
| With fresh Larimichthys crocea fish as raw material, the Larimichthys crocea fish oil was extracted by petroleum ether (boiling range 30-60 ℃). The acid value, peroxide value, anisidine value, conjugated diene value, fatty acid composition, content of tocopherols, cholesterol, squalene, volatile components and phospholipid composition of Larimichthys crocea fish oil were determined. The results showed that the yield of Larimichthys crocea fish oil was (31.25±3.66)%, and the acid value, peroxide value, anisidine value and conjugated diene value were (0.59±005)mgKOH/g, (550±0.76) mmol/kg, 030±006 and 2232±1.09, respectively. A total of 17 fatty acids were detected in Larimichthys crocea fish oil, and the content of unsaturated fatty acids was 67.27%, in which the oleic acid, linoleic acid, DHA and EPA accounted for (31.03±010)%,(1221±0.07)%,(7.21±0.12)% and (4.48±003)%,respectively. There were four tocopherols in Larimichthys crocea fish oil,α-tocopherol content was 4.18 mg/100 g, and the contents of β-tocopherol, γ-tocopherol and δ-tocopherol were all below 0.12 mg/100 g. The contents of squalene and cholesterol in Larimichthys crocea fish oil were 40 mg/100 g and 380 mg/100 g, respectively. A total of 31 volatile components were identified in Larimichthys crocea fish oil, mainly including aldehydes, ketones, alcohols and alkanes. The high contents of phospholipids in Larimichthys crocea fish oil were PG (30∶ 0/16∶ 0) (19.61 mg/g) and PG (28∶ 0/16∶ 1) (10.87 mg/g). |
