Researchers often found that herbal additives to chicken feed can favorably alter the fatty acid profile of the meat. The most desirable effects of diet modification comprise an increased content of polyunsaturated fatty acids (PUFA) and monounsaturated fatty acids (MUFA) and a reduced content of saturated fatty acids (SFA) in the breast and thigh muscles. A modified fatty acid profile contributes to improvement in the quality of poultry meat, which is reflected in its increased consumption. However, it may be problematic that PUFAs are oxidized easier than other lipids, which can have a negative impact on the sensory traits of meat. By contrast, herbs and herbal products contain antioxidants that can prevent the oxidation of unsaturated fatty acids and cholesterol present in animal-origin products and increase the antioxidant potential of the consumer's body. This paper aims to review the influence of herbal additives for broiler chicken diets on the fatty acid profile of poultry meat. Special attention was paid to changes in the content of SFAs, MUFAs, and PUFAs, but also alterations in the omega-6:omega-3 ratio. The presented reference literature supports the statement that herbs and bioactive components of herbs added to chicken diets can improve the quality of broiler chicken meat by altering the content of fatty acids.
研究人员经常发现,鸡饲料中的草药添加剂能够有利地改变鸡肉的脂肪酸谱。饮食调整最理想的效果包括鸡胸肉和鸡腿肉中多不饱和脂肪酸(PUFA)和单不饱和脂肪酸(MUFA)含量增加,饱和脂肪酸(SFA)含量降低。改良后的脂肪酸谱有助于提高禽肉品质,这体现在其消费量的增加上。然而,多不饱和脂肪酸比其他脂质更容易被氧化,这可能会对肉的感官特性产生负面影响,这可能是个问题。相比之下,草药和草药产品含有抗氧化剂,能够防止动物源产品中存在的不饱和脂肪酸和胆固醇被氧化,并提高消费者身体的抗氧化能力。本文旨在综述草药添加剂对肉鸡日粮中禽肉脂肪酸谱的影响。特别关注了饱和脂肪酸、单不饱和脂肪酸和多不饱和脂肪酸含量的变化,以及ω-6:ω-3比值的改变。所引用的参考文献支持这样一种观点,即添加到鸡日粮中的草药及其生物活性成分可以通过改变脂肪酸含量来提高肉鸡的肉质。
