Meat and meat products are generally recognized as good sources of high biological value proteins, fat-soluble vitamins, minerals, trace elements and bioactive compounds. Changes in socioeconomic factors in recent years have increased the consumer's preference for ready to eat foods including meat products. The processing of meat and meat products leads to generation of many functional compounds beneficial to human health but most of those foods are rich in fat, added salts but deficient in complex carbohydrates like dietary fiber and pose a health hazard that somehow is proved to be a predisposing factor for cardiovascular diseases, colon cancer, obesity including diabetes mellitus. With increasing consciousness among consumers about their nutrition and well being, there is a growing concern over nutritional diseases of affluence. Therefore an increase in dietary fiber inclusion in daily diet has been recommended. For adults, the recommended acceptable intakes of dietary fiber are 28-36 g/day, 70-80 % of which must be insoluble fiber. The insoluble fraction of dietary fiber has been related to intestinal regulation whereas soluble fiber is associated with decrease in cholesterol level and absorption of intestinal glucose. So incorporation of dietary fibers from different sources in meat products would help to enhance their desirability. Dietary fiber sources are generally agricultural byproducts that are comparatively cheap and incorporation in meat products reduces its overall cost. Whole grains and cereal brans are the rich source of insoluble fiber and pectins, gums, starch and other storage polysaccharides have high content of the soluble fraction. With this background, the effect of various dietary fibers on the quality attributes of meat and meat products with its physiological role has been reviewed here.
肉类和肉制品通常被认为是高生物价值蛋白质、脂溶性维生素、矿物质、微量元素和生物活性化合物的良好来源。近年来社会经济因素的变化增加了消费者对包括肉制品在内的即食食品的偏好。肉类和肉制品的加工会产生许多对人体健康有益的功能性化合物,但这些食品大多富含脂肪、添加盐,而膳食纤维等复合碳水化合物含量不足,存在健康风险,在某种程度上被证明是心血管疾病、结肠癌、肥胖症(包括糖尿病)的诱发因素。随着消费者对自身营养和健康意识的提高,人们对营养过剩疾病的关注度也在不断增加。因此,建议增加日常饮食中膳食纤维的摄入量。对于成年人,膳食纤维的推荐可接受摄入量为28 - 36克/天,其中70 - 80%必须是不溶性纤维。膳食纤维的不溶性部分与肠道调节有关,而可溶性纤维与胆固醇水平降低和肠道葡萄糖吸收有关。因此,在肉制品中添加不同来源的膳食纤维有助于提高其吸引力。膳食纤维来源通常是相对便宜的农业副产品,将其添加到肉制品中可降低其总成本。全谷物和谷物麸皮是不溶性纤维的丰富来源,而果胶、树胶、淀粉和其他储存多糖则含有高含量的可溶性部分。在此背景下,本文综述了各种膳食纤维对肉类和肉制品品质特性及其生理作用的影响。
