人造胶原肠衣的研究进展

肠衣作为食品包装材料,对维持肉制品的品质、延长货架期具有重要作用。随着肠衣需求量的增加,天然肠衣市场供不应求,为人造肠衣的出现和发展提供了机会。其中人造肠衣包括塑料肠衣、纤维素肠衣和胶原肠衣。在加工过程中每种肠衣都体现出各自的特点同时存在不同的亟待解决的问题。人造胶原肠衣在可食性、收缩性、黏着性等性能方面与天然肠衣相似,在资源稳定性和食品安全性等方面优于天然肠衣。胶原肠衣兼有天然肠衣和人造肠衣两者的优点,因此具有非常大的市场前景。本文在综述了肠衣类型的基础上,对比了国内外胶原肠衣的研究进展,总结了胶原肠衣的制备方法,并对胶原肠衣尤其是水产胶原肠衣的发展前景进行了展望,以期对胶原肠衣的研究提供理论基础。

Review on artificial collagen casing

As food packaging materials, sausage casings play an important role in maintaining the quality of meat products and extending the shelf life. With the increase of sausage casings demand, the natural casing market is in short supply, which provides an opportunity for the appearance and development of artificial casing. The synthetic casings include plastic casings, cellulose casings and collagen casings. In the process of processing, different kinds of casings show their own characteristics and also the problems to be solved. Artificial collagen casings are similar to natural casings in terms of edible, contractile and adhesive properties, and superior to natural casings in terms of resource stability and food safety. Collagen casing has both advantages of natural casing and artificial casing, so it has a very large market prospect. On the basis of summarizing the types of casings, this paper compared the research progress of collagen casings of the casing markets, and summarized the preparation methods of collagen casings, moreover prospected the development prospect of collagen casings, especially aquatic collagen casings, so as to provide theoretical basis for the research on collagen casings.
