【摘要】 传统的制革工业在生产过程中要产生占原皮重 60 %以上的固体废弃物。由于废弃物没有被充分利用 ,使其成为制革工业污染严重的重要原因之一。随着资源、环境等全球性生态问题的日益严峻 ,“制革废弃物资源化”现已成为国内外关注的重要课题。胶原作为天然的生物质资源 ,在食品、医药、化妆品、饲料、肥料等工业中的应用和经济地位正日益突出。本文简要评述了胶原适用于食品的属性 ,以及从制革边角固体废弃物中提取食用胶原的方法和应用更多还原

【Abstract】 Over 60% of the raw hides (by weight) were generated in form of solid waste in the traditional leather process, which consists largely of collagen protein. And because of insufficient utilization, it became one of the main factors resulting pollution. With the background of the global ecological problems, such as resource and environment increasingly serious, the conversion of solid leather waste to reusable, especially high additional-value products is presently being an attractive subject in home and abroad. As a kind of natural biomass, collagen plays more and more important roles in the food, medicine, cosmetics, feed and fertilizer industry. Some methods of extracting collagen products from hide offal and its application in the food industry are summarized in this paper.更多还原
