近几年人们对于肉制品的摄入量逐渐增加,而传统肉制品中较高的脂肪含量给人们带来了很多慢性疾病。由于脂肪替代物在肉制品中的应用可有效降低脂肪的摄入,且能预防高脂膳食所引起的一系列疾病,弥补脂肪的减少给肉制品所带来的口味上的损失,因此低脂肉制品的研究势在必行。本文基于国内外脂肪替代物的发展现状,从单一型脂肪替代物(蛋白质类、碳水化合物类、脂质类)和复合型脂肪替代物(由不同基质来源物按照一定比例结合在一起协同发挥脂肪替代作用的混合物)2个方面阐述了各自对于低脂肉制品的感官特性和质构特性影响的研究进展还有脂肪替代物应用中存在的问题,并对脂肪替代物发展方向做出了展望,以期为低脂肉制品的研发提供一定的参考。 相似文献

随着消费者越来越注重饮食与健康之间的关系,如何替代肉制品中含有大量饱和脂肪酸的动物脂肪已经成为肉品科学领域研究的热点问题。然而,单纯地过多降低动物脂肪使用量会大大降低肉制品的风味和柔嫩多汁的口感。近年来,利用具有独特结构和功能特性的乳液凝胶作为一种新型的动物脂肪替代物越来越受到重视。本文在国内外相关研究的基础上,全面综述了乳液凝胶的制备方法、品质特性和在低脂肉制品中的应用情况,以期为乳液凝胶替代动物脂肪在肉制品中的应用提供良好的理论依据,也为生产高附加值的新型健康低脂肉制品提供创新性技术指导。 相似文献

钠盐是当前肉制品加工中采用比较广泛的一种咸味剂,其能够有效地提升产品的风味、降低肉制品水分活度,在赋予肉制品美好味道的同时有效地延长产品的保质期。与此同时,钠盐还具有稳定肉制品脂肪乳化性、改善产品保水性与多汁性的作用,有效提高加工肉制品的食用品质。由于钠盐的上述作用及低廉的成本,其在肉制品的加工使用中比较频繁。但是,当前大部分肉制品的钠盐施用量都存在超标现象,这对食品质量及消费者安全造成了重大影响。为此,本文将对低钠肉制品的开发进行分析和研究,探讨其研究进展。 相似文献

The 21st-century consumer is highly demanding when it comes to the health benefits of food and food products. In the pursuit of attracting these consumers and easing the rise in demand for high-quality meat products, the processed meat sector is intensely focused on developing reformulated, low-fat, healthy meat products. Meat and meat products are considered the primary sources of saturated fatty acids in the human diet. Therefore, these reformulation strategies aim to improve the fatty acid profile and reduce total fat and cholesterol, which can be achieved by replacing animal fat with plant-based oils; it could be performed as direct inclusion of these oils or pre-emulsified oils. However, emulsions offer a viable option for incorporating vegetable oils while avoiding the multiple issues of direct inclusion of these oils in meat products. Processed meat products are popular worldwide and showing a gradually increasing trend of consumption. Various types of plant-based oils have been studied as fat replacers in meat products. This review will focus on possible methods to reduce the saturated fatty acid content in meat products. 相似文献

肌原纤维蛋白(myofibrillar protein,MP)作为肌肉中具有重要生物学功能的结构蛋白,能单独形成凝胶或作为凝胶的主要部分。MP的凝胶作用机理及凝胶特性已成为肉类科学研究的热点。明确各种添加剂对肉制品品质的影响,为开发健康的低脂肉制品提供依据。多糖具有良好的生物相容性且来源广泛、价格低廉,被广泛用于改善肉制品的品质。然而,目前多糖调节MP凝胶特性的研究并没有得到较为全面的归纳与总结。故本文概括了多糖的定义、分类以及功能特性,总结了多糖对MP凝胶特性的影响以及多糖在肉制品中的应用,以期为低脂肉制品的生产提供理论依据,并提出未来的研究方向。 相似文献

A mixture design approach was used to evaluate interactions between potato starch, locust bean gum and κ-carrageenan and their effect on cooking yield, expressible moisture, texture and color in low-fat sodium-reduced sausages formulated with potassium and calcium chloride. Starch had a notable influence on cooking yield and texture, increasing product hardness and resilience as starch proportion increased. The added salt did not allow complete starch granule gelatinization and swelling, which negatively affected water retention, cohesiveness and lightness. Locust bean gum and κ-carrageenan improved cooking yield and reduced expressible moisture in formulations containing higher proportions of potato starch. The presence of other ions could have enhanced κ-carrageenan functionality and its synergistic interaction with locust bean gum, improving texture and water retention, with only minor effects on sausage color. At the lower tested proportions starch can be used as an extender in low-fat cooked meat products if κ-carrageenan and locust bean gum are included in similar proportions. 相似文献

The effect of high-pressure pretreatment (HPP, 100–300 MPa) before heating on the water holding capacity (WHC) and cooking loss (CL) of sodium-reduced (1.35% NaCl) frozen chicken breast gels with the organic anion types potassium lactate (KL-gel) and potassium citrate (KC-gel) was investigated. The results showed that 100–300 MPa could significantly decrease the CL of both gels, and 200 MPa increased the WHC of the KC-gel (P?<?0.05). HPP could decrease the storage modulus (G′) of meat batters, increase the thermal stability of their proteins, facilitate gelation with a dense and uniform microstructure, and immobilize free water, thus improving the gel’s water retention. The water retention of the pressurized sodium-reduced gel varied with the organic anion types of salts. The water retention was better with pressurized KC-gel than with KL-gel, resulting from higher pH and thermal stability of the batters. These results indicate that proper HPP could improve the water retention of sodium-reduced meat gels with organic potassium salts, thus increasing the economic benefit and properties of sodium-reduced products from frozen meat. 相似文献
