摘要/Abstract

摘要： 【目的】本试验旨在研究蛋鸭饲粮中n-6/n-3多不饱和脂肪酸(n-6/n-3 PUFA)对鸭蛋中脂肪酸组成和咸蛋黄品质的影响。【方法】试验选用健康、体重相近的21周龄福建龙岩山麻鸭180只,随机分为2组,每组6个重复,每个重复15只鸭。分别饲喂玉米-豆粕(对照组)和玉米-豆粕-亚麻籽(试验组)饲粮,n-6/n-3 PUFA分别为16和8,试验周期为12周。饲养试验结束后,采集新鲜鸭蛋测定脂肪酸组成,腌制咸蛋,测定咸蛋黄内质特性、质构特性、风味和滋味。【结果】与n-6/n-3 PUFA 16饲粮相比,n-6/n-3 PUFA 8饲粮①增加了鲜蛋黄中C18∶0、C20∶0、C22∶0、C22∶1n9、C18∶2n6c、C18∶3n3、C20∶3n6、C20∶4n6、n-6 PUFA以及n-3 PUFA含量,降低了鲜蛋黄中n-6/n-3 PUFA(由10.20降至5.65,P＜0.05);②降低了咸蛋黄的硬心率和硬心比重(P＜0.05),不影响出油率和沙性(P＞0.05);降低了咸蛋黄的硬度,增加了弹性(P＜0.05),但黏附性、内聚性、胶黏性和咀嚼性无显著变化(P＞0.05);降低了咸蛋黄中醇醚醛酮类的气味(P＜0.05);降低了咸蛋黄的苦味和鲜味,增加了滋味的丰富性(P＜0.05),对涩味和咸味无显著影响(P＞0.05)。【结论】蛋鸭饲粮n-6/n-3 PUFA由16降为8时,可降低鲜蛋黄中n-6/n-3 PUFA,改善咸蛋黄品质和风味。

Abstract: 【Objective】 This study was conducted to investigate the effects of dietary n-6/n-3 PUFA ratio on fatty acid composition in duck eggs and quality of salted egg yolks in laying ducks.【Method】 A total of 180 healthy 21-week Fujian Longyan laying ducks were randomly divided into 2 treatments,with 6 replicates of 15 ducks each.They were fed corn-soybean meal and corn-soybean meal-linseed diets,and the n-6/n-3 PUFA ratio in diets were 16 and 8,respectively.The trial lasted for 12 weeks.At the end of week 12,fresh duck eggs were collected to determine the fatty acid composition,and the salted egg yolks were prepared to determine the yolk interior properties,texture properties,odor and flavor.【Result】 ①Compared with the diet with the ratio of n-6/n-3 PUFA was 16,the diet with the ratio of n-6/n-3 PUFA was 8 increased the contents of C18∶0,C20∶0,C22∶0,C22∶1n9,C18∶2n6c,C18∶3n3,C20∶3n6,C20∶4n6,n-6 PUFA and n-3 PUFA in egg yolk,and decreased the ratio of n-6/n-3 PUFA in egg yolk (10.20 to 5.65,P＜0.05).②Dietary decreased n-6/n-3 PUFA ratio reduced the hardening ratio and its weight of salted egg yolk (P＜0.05),but had no significant effect on oil output and sandiness (P＞0.05).As to the texture properties,the hardness was decreased,the springiness was increased (P＜0.05),and there were no significant differences in adhesiveness,cohesiveness,gumminess and chewiness of salted egg yolk (P＞0.05).The odor of alcohol,ether,aldehyde and ketone in salted egg yolk was decreased with dietary decreased n-6/n-3 PUFA ratio (P＜0.05).As to the flavor,dietary decreased n-6/n-3 PUFA ratio reduced the bitterness and umami,increased the richness of salted egg yolk (P＜0.05),and no significant effect was observed in astringency and saltiness (P＞0.05).【Conclusion】 Overall,dietary decreased n-6/n-3 PUFA ratio (8 vs 16) could decrease the ratio of n-6/n-3 PUFA in the fresh egg yolk,improve the quality and flavor of salted egg yolk.

Key words: n-6/n-3 PUFA; duck egg; fatty acid composition; quality of salted egg yolk
