摘　　要：DHA能有效促进大脑发育、改善视力、预防心血管系统疾病等,但其在人体内的生成量不能满足需求,需要靠食物获得。开发DHA营养强化鸡蛋,可以为人们获取足量、廉价、优质的DHA提供有效途径。为了加强对DHA营养强化鸡蛋的研发,推动其进一步发展,从DHA的生理功能视角出发,分析了DHA营养强化鸡蛋开发优势、饲料脂肪酸对鸡蛋中DHA的调控机制,阐述了DHA营养强化鸡蛋的脂质组成、饲料中DHA的来源及鸡蛋中DHA的稳定性。富含DHA的日粮可生产富集DHA的鸡蛋,且蛋黄中的DHA具有较高的稳定性,同时DHA营养强化鸡蛋食用方便、便于保存,且价格相对低廉,因此DHA营养强化鸡蛋具有广阔的发展前景。Docosahexaenoic acid(DHA) is effective in promoting brain development, improving vision and preventing cardiovascular system diseases, but its production in the human body does not meet the demand and needs to be obtained from food. The development of DHA fortified eggs can provide an effective way for people to obtain sufficient, cheap and high-quality DHA. To strengthen the research and promote further development, the advantages of DHA fortified eggs and the regulation mechanism of feed fatty acids to DHA were analyzed from the perspective of physiological function of DHA. In addition, the lipid composition of DHA fortified eggs, sources of DHA in feed, and the stability of DHA in eggs were described. DHA-enriched diets can produce DHA-enriched eggs, and the DHA in the yolk has high stability. DHA fortified eggs provide convenience for consumption, storage and saving costs, so DHA fortified eggs have a wide range of development prospects.
