With the wide acceptance of the long-chain (LC) n-3 PUFA EPA and DHA as important nutrients playing a role in the amelioration of certain diseases, efforts to understand factors affecting intakes of these fatty acids along with potential strategies to increase them are vital. Widespread aversion to oil-rich fish, the richest natural source of EPA and DHA, highlights both the highly suboptimal current intakes in males and females across all age-groups and the critical need for an alternative supply of EPA and DHA. Poultry meat is a popular and versatile food eaten in large quantities relative to other meats and is open to increased LC n-3 PUFA content through manipulation of the chicken's diet to modify fatty acid deposition and therefore lipid composition of the edible tissues. It is therefore seen as a favourable prototype food for increasing human dietary supply of LC n-3 PUFA. Enrichment of chicken breast and leg tissue is well established using fish oil or fishmeal, but concerns about sustainability have led to recent consideration of algal biomass as an alternative source of LC n-3 PUFA. Further advances have also been made in the quality of the resulting meat, including achieving acceptable flavour and storage properties as well as understanding the impact of cooking on the retention of fatty acids. Based on these considerations it may be concluded that EPA- and DHA-enriched poultry meat has a very positive potential future in the food chain.
随着长链(LC)n-3 PUFA EPA 和 DHA 作为重要营养物质被广泛接受,其在改善某些疾病方面的作用受到重视,因此,了解影响这些脂肪酸摄入的因素以及增加这些脂肪酸摄入的潜在策略至关重要。人们普遍不喜欢富含油脂的鱼类,因为鱼类是 EPA 和 DHA 的最丰富的天然来源,这突出表明,所有年龄段的男性和女性目前的摄入量都非常不理想,而且非常需要 EPA 和 DHA 的替代来源。禽肉是一种受欢迎且用途广泛的食品,相对于其他肉类,其食用量较大,通过操纵鸡的饮食,可以增加禽肉中 LC n-3 PUFA 的含量,从而改变脂肪酸的沉积,进而改变可食用组织的脂质组成。因此,禽肉被视为增加人类 LC n-3 PUFA 饮食供应的理想原型食品。用鱼油或鱼粉来增加鸡胸肉和鸡腿肉中的 LC n-3 PUFA 含量已经得到了很好的证实,但是,可持续性问题的担忧导致人们最近开始考虑将藻类生物量作为 LC n-3 PUFA 的替代来源。在提高肉品质量方面也取得了进一步的进展,包括实现可接受的风味和储存特性,以及了解烹饪对脂肪酸保留的影响。基于这些考虑因素,可以得出结论,富含 EPA 和 DHA 的禽肉在食物链中具有非常积极的未来潜力。
