摘要:
为测定青壳Ⅱ号海鸭蛋中的营养成分，参照食品中营养含量测定的国标方法，对青壳Ⅱ号海鸭蛋进行了营养测定评价。结果表明，青壳Ⅱ号海鸭鲜蛋主要营养成分为水分70.45%，粗蛋白12.74%、粗脂肪12.08%、卵磷脂3.90%，氨基酸总量占干重的51.32%；青壳Ⅱ号海鸭鲜蛋含有对人体有益的微量元素Ca 480.2 mg•kg−1、Zn 13.9 mg•kg−1，Cu 0.93 mg•kg−1，Fe 52.7 mg•kg−1，Mg 195.0 mg•kg−1，Mn 0.32 mg•kg−1，其中，Ca、Zn、Fe、Mg含量显著高于其它禽蛋。青壳Ⅱ号海鸭蛋总体营养价值均高于普通海鸭蛋、普通鸭蛋及土鸡蛋，本实验为推广青壳Ⅱ号蛋鸭品种的滩涂放养模式及其制品的加工提供了理论依据。
In order to determine the nutritional components of the numberⅡ cyan sea duck eggs, the expe-riment refers to the GB methods which contain the determination of nutrient contents in food to determine and evaluate the nutrition of the numberⅡcyan sea duck eggs. The results show that the numberⅡ cyan sea duck eggs have the main nutritional components of moisture 70.45%, crude protein 12.74%, crude fat 12.08%, lecithin 3.90%, respectively. Amino acids accounted for 51.32% of the total dry weight. The numberⅡ cyan sea duck eggs contain microelements of Ca 480.2 mg•kg−1, Zn 13.9 mg•kg−1, Cu 0.93 mg•kg−1, Fe 52.7 mg•kg−1, Mg 195.0 mg•kg−1, Mn 0.32 mg•kg−1, which are beneficial to human bodies. Among them, content of microelements of Ca, Zn, Fe, Mg was significantly higher than that of other eggs. Compared with the ordinary sea duck eggs, ordinary duck eggs and native eggs, nutritional value of the numberⅡ cyan sea duck eggs is the highest. The experiment provides the theoretical basis for extending mudflat farming of numberⅡcyan sea duck and processing of egg products.
