亚硝酸盐是食品加工行业中较为常见的一种添加剂,主要应用于腌腊肉制品,亚硝酸盐不仅能够保持肉制品的风味、色泽同时还具有良好的防腐抗氧化作用。但是亚硝酸盐存在一定的毒性,若过量使用会产生致癌物致使肉制品的食用安全性降低。由于消费者担心亚硝酸盐对人体健康的影响,对天然有机的肉制品需求量逐渐增加,因此寻找出能够替代亚硝酸盐功效的新型添加剂势在必行。本文主要综述了国内外关于亚硝酸盐新型替代物在肉制品中应用情况的研究进展,包括植物性替代物、微生物替代物、有机酸类替代物等,并对这些替代措施今后的应用前景进行了展望,旨在为现代肉制品加工企业能生产出安全优质的肉制品提供一定的科学理论依据。 相似文献

以猪肉为原料,研究商业化天然植物提取物Nature 10 CS、T-4N DV CN和T-4N W DV对传统腌腊和酱卤肉制品色泽等特性的影响。结果显示:与常规添加亚硝酸盐产品相比,所选用的3 种天然植物提取物对产品的pH值、水分含量和aw不存在显著影响,而Nature 10 CS使腌制、卤煮后的酱卤肉制品以及腌制、风干和煮制后的腌腊肉制品呈现良好的色泽,且亚硝酸盐残留量低于4 mg/kg。尽管其色泽比常规添加亚硝酸盐的产品稍差,但已满足产品商品特性需求。添加T-4N DV CN和T-4N W DV产品的色泽效果不佳,因此不能作为亚硝酸盐的替代物。含微量亚硝酸盐的Nature 10 CS可满足传统腌腊和酱卤肉制品的发色需求,且在产品中残留甚微。 相似文献

不需额外添加亚硝酸盐--形象更健康 即食型包装肉制品,如火腿、培根、法兰克福香肠等,代表了当今全球最大的冷冻食品市场.但传统的熟肉制品和乳化类香肠用亚硝酸盐腌制,而亚硝酸盐已越来越不被消费者接受,于是兼具安全性和天然性、以及标签友好特性的食品配料受到厂家的青睐.丹尼斯克的TEXEL(R) NatuRed冻干菌种是全天然解决方案,能赋予肉制品与添加亚硝酸盐的产品类似的色泽、风味和货架期. 相似文献

硝酸盐和亚硝酸盐在腌肉制品加工中同时起着发色、抑菌、抗氧化和提高风味的作用,但硝酸盐和亚硝酸盐与肉中的二级胺反应会形成致癌物质N-亚硝胺,所以寻求一种更加安全有效的硝酸盐和亚硝酸盐替代方式,在实际生产中具有重要意义。本文就无硝腌肉制品在亚硝酸盐发色作用、抑菌作用和抗氧化作用的替代物方面开展的研究工作进行综述,提出了天然腌制的概念,重点介绍目前国内外利用蔬菜替代亚硝酸盐的方法,包括将蔬菜粉(或汁)中的硝酸盐用硝酸盐还原菌转化为亚硝酸盐后加入腌肉制品中(先发酵法)和将蔬菜粉(或汁)加入肉馅中再发酵(后发酵法)两种生产方式,并对目前的研究现状、进展、存在问题及今后发展方向进行了论述,以期为生产安全腌肉制品提供借鉴。 相似文献

Nitrite is one of the most important additives in meat products. In most countries the use of the additive is limited and either the ingoing or the residual amounts are regulated by laws. N-nitrosamines are formed by amines or amino acids with nitrite in meat. Investigations on the occurrence of N-nitrosamines in meat products have been carried out in many countries around the world. In this paper, mechanism of N-nitrosamine formation and its corresponding influence factors in meat products were reviewed. The contents of N-nitrosamines in meat and analytical techniques for the compounds were also described. 相似文献

N-亚硝胺是一类公认的带有强毒性的化合物,是在弱酸性条件下由亚硝酸盐和二级胺反应生成的一种致癌物质,在肉制品特定的加工环境中容易生成。以往研究表明:人类是挥发性亚硝胺引起癌症的易感群体,这些物质存在于食物中被认为是某些人类癌症包括胃癌、食道癌及鼻咽癌等癌症的致病危险因子,所以国内外对食物中挥发性亚硝胺的检测、形成和控制进行了大量的研究。本文介绍了肉制品中N-亚硝胺的来源和危害;总结了该类化合物的检测方法,如气相色谱法(GC)、气相色谱质谱联用法(GC-MS)、高效液相色谱法(HPLC)等;应用辐照和天然植物等阻断剂消除和控制肉制品中N-亚硝胺技术措施的研究进展。 相似文献

BACKGROUND: Nitrite is a key ingredient the manufacture of meat products, forming a stable pink color characteristic of cured products, retarding the development of rancidity and off‐odors and flavors during storage, and preventing microbial growth. The negative aspects of nitrite and the demands for healthy foods result in the need to reduce nitrite in cured meat products. Paprika or tomato has been employed as natural pigments in meat products. The objective of this work was to determine the effect of incorporating paprika powder or tomato paste on the texture, rancidity and instrumental and sensory color compensation in nitrite‐reduced meat batters. RESULTS: Addition of tomato paste improved moisture content, resulting in harder but less cohesive samples as compared to control and paprika‐containing meat batters. Color characteristics of reduced nitrite samples obtained higher a* red coloration (8.9 for paprika and 7.7–8.0 for tomato paste), as compared to control samples (5.65). Instrumental color was low in control samples, with high values for tomato paste and paprika samples. Nonetheless, tomato paste used to compensate color in nitrite‐reduced meat batters was ranked closer to the control sample in sensory evaluation. CONCLUSION: Color characteristics—instrumental and sensory—in these kinds of meat products were enhanced by the addition of 2.5–3.0% of tomato paste, presenting results close to the non‐reduced nitrite control. Similarly, antioxidant components of tomato paste or paprika reduced lipid oxidation. Nitrite reduction from 150 to 100 ppm could be achieved employing tomato paste as a natural pigment to improve color and texture. Copyright © 2011 Society of Chemical Industry 相似文献
