摘要
本试验通过测定低胆固醇沙棘鸡蛋的蛋品质、营养成分、类胡萝卜素含量、胆固醇含量,并和普通鸡蛋进行比较分析。结果表明,沙棘鸡蛋的蛋黄颜色(罗氏色泽)、蛋黄比例、蛋黄/蛋清比例、蛋重较普通鸡蛋分别提高了26.21%、16.00%、48.72%、10.54%(P <0.05),2种鸡蛋的哈夫单位数值均在72以上,蛋比重为1.06～1.10、蛋壳厚度均在0.35 mm以上,且无显著性差异(P> 0.05);沙棘鸡蛋的灰分含量、粗脂肪含量、蛋白质含量较普通鸡蛋分别提高了21.15%、26.59%、14.51%(P <0.05),并且其蛋黄和全蛋的类胡萝卜素含量较普通鸡蛋分别提高了85.81%、44.09%(P <0.01);沙棘鸡蛋蛋黄、蛋清以及全蛋胆固醇含量相对于普通鸡蛋降低了45.17%、71.31%、48.64%(P <0.01)。沙棘鸡蛋的营养价值、口感明显优于普通鸡蛋,蛋品质和等级也高于普通鸡蛋,类胡萝卜素含量的增加和胆固醇含量的降低提高了沙棘鸡蛋的保健作用,使营养丰富的鸡蛋又增加了自身的附加值。
To study the quality,nutrients,carotenoid and cholesterol from sea buckthorn egg and provide a theoretical basis for utilization of the development of healthy and low cholesterol health egg.The egg quality,nutrient content,carotenoid content and cholesterol content of low cholesterol sea buckthorn egg were determined and compared with ordinary eggs.The results showed that the yolk color,yolk ratio,egg yolk/egg white ratio,weight of sea buckthorn egg were increased by 26.21%,16%,48.72%,10.54%compared with ordinary egg,respectively(P<0.05),and haugh unit between the two kinds of eggs were more than 72.The egg proportion between the sea buckthorn egg and ordinary egg was from 1.06 to 1.10,and the shell thickness of egg was above 0.35 mm,and no significant difference(P>0.05).The ash,crude fat and protein content of sea buckthorn egg were increased by 21.15%,26.59%and 14.51%compared with ordinary egg,respectively(P<0.05).The content of carotenoids in egg yolk and whole egg of sea buckthorn were increased by 85.81%,44.09%(P<0.01).The cholesterol content of seabuckthorn eggs yolk,egg white and whole eggs were decreased by 45.17%,71.31%and 48.64%compared with ordinary eggs(P<0.01).The results obtained in this study indicated that the nutritive value of sea buckthorn eggs was obviously better than that of ordinary eggs,and the taste,quality and grade of the eggs were also better than the ordinary egg.The increase of carotenoid content and decrease of cholesterol content add the health effect and value of the sea buckthorn eggs.
