摘要:

全球约有1/2的人口正面临着微量营养素摄取不足“隐性饥饿”的问题,学龄前儿童、孕龄女性的缺铁贫血比例更是高达1/3。缺铁会造成机体氧气运输和造血过程受阻、金属酶的合成与功能异常、能量代谢障碍、机体免疫功能下降等。提高农副产品中微量营养素,尤其是铁的含量和生物有效性,对解决这一人类营养与健康问题具有重大的科学和实践意义。动物源铁主要以血红素铁和铁蛋白形式存在,其生物利用率显著高于植物源铁和常见铁补充剂,是较为理想的补铁源。但大部分动物源食品中的铁含量不高,如何增加动物肉、蛋、奶中铁含量鲜有研究。本文从畜禽体内铁代谢和分布特征出发,对比主要铁源在生物体内的生物利用效率,分析影响畜禽产品中铁富集的主要因素,并综述了富铁动物性食品的研发进展和市场应用前景。

Abstract:

About one half of the global population is facing the problem of “hidden hunger” due to inadequate intake of micronutrients all over the world, the proportion of iron deficiency anemia in preschool children and gestational age women is up to one third. Iron deficiency leads to obstruction of oxygen transportation and hematopoiesis, abnormal synthesis and function of metalloenzymes, energy metabolism disorder and decreased immune function of the body. It is of great scientific and practical significance to improve the content and bioavailability of micronutrients, especially iron, in agricultural and sideline products to solve this problem of human nutrition and health. Animal-derived iron as an ideal iron source mainly exists in the form of heme iron and ferritin with a significantly higher bioavailability compared with plant-derived iron and common iron supplements. However, the iron content in most animal-derived foods is limited, and few studies has done on how to increase the iron content of animal meat, eggs and milk. Based on the characteristics of iron metabolism and distribution in livestock and poultry, in this review, we compare the bioavailability of main iron sources in organisms, analyze the factors affecting iron enrichment in livestock and poultry products and discuss the feasibility of development and application of iron-rich animal foods.

Key words: functional foods, animal-derived ion-rich foods, iron enrichment, hidden hunger, heme iron
