摘要
为了研究海东鸡蛋品质特性及营养成分,该试验选取 240 日龄海东鸡鸡蛋 60枚,其中 30个蛋进行蛋品质常规指标的测定.另外 30 个鸡蛋制作成3 个混样(每个混样 10 枚鸡蛋)用做营养成分的测定.结果表明:海东鸡蛋壳强度为 2.77 kg/cm2,虽在标准范围内,但数值偏低;蛋黄颜色和蛋黄比例均高于同为地方蛋肉兼用型的二郎山山地鸡.海东鸡蛋黄的脂肪和卵磷脂含量均高于海兰褐、京白 939、苏禽青壳蛋鸡和如皋黄鸡等市场常见的品牌鸡蛋.海东鸡蛋的必需氨基酸/总氨基酸和必需氨基酸/非必需氨基酸的值均高于FAO/WHO的模型标准值.海东鸡蛋脂肪酸中不饱和脂肪酸占比约为 63.99%,含量最高的为油酸 45.96%;饱和脂肪酸占比约为 35.66%,其中含量最高的是棕榈酸 25.45%.可见,海东鸡蛋品质良好,营养成分丰富,但蛋壳强度选育需要进一步加强.
Abstract
To study the quality characteristics and nutritional components of Haidong eggs,60 240-day-old Haidong eggs were selected,of which 30 eggs were used to determine the routine indexes of egg quality.Another 30 eggs were made into 3 mixed samples(10 eggs per mixed sample)for the determination of nutrients.The results showed that the eggshell strength of Haidong chicken was 2.77 kg/cm2,which was within the standard range,but the value was low.The yolk color and yolk ratio were higher than those of Erlang Mountain Chicken,which was also a local egg-meat dual-purpose type.The contents of fat and lecithin in the egg yolk of Haidong chicken were higher than those of common brand eggs in markets such as Hailan brown,Jingbai 939,Suqin blue-eggshell chicken,and Rugao yellow chicken.The essential amino acid/total amino acid and essential amino acid/non-essential amino acid values of Haidong eggs were higher than the FAO/WHO model standard values.The proportion of unsaturated fatty acids in the fatty acids of Haidong eggs was about 63.99%,and the highest content was oleic acid 45.96%.The proportion of saturated fatty acids was about 35.66%,and the highest content was palmitic acid(25.45%).It can be seen that Haidong eggs have good quality and rich nutrients,but the selection of eggshell strength needs to be further strengthened.
