项目摘要

The fish industry is an important component of Canada's agri-food sector, and generates millions of dollars in revenue each year. However, fish stocks have been declining in recent years. This fact coupled with the seasonal nature of the seafood harvest and the high perishability of the raw material make it necessary to develop more effective procedures to reduce spoilage to ensure availability of the products for human consumption. The two main factors responsible for the rapid loss of fish quality are microbial activity and autolysis by endogenous enzymes. Thus far, fish spoilage by microorganisms has been well studied, while the contribution of autolysis to the spoilage phenomenon is less well studied. The proposed study will investigate novel approaches based on high pressure in combination with other barriers such as natural antioxidants and low temperature storage, as tools for preserving premium seafood quality. Seafood processing also generates high volumes of discards that are currently not put to high value uses. However, the discards are rich is useful biochemicals such as enzymes that may be recovered in pure forms for several commercial applications. The global market for enzymes is estimated at 1.3 billon dollars (US) per year, with a growth rate of 12-15% per year. There is a growing need to discover new sources of enzymes to meet the market demands, and fish processing discards represent an underutilized resource material with potential to fill this need. In the proposed studies, two groups of fish enzymes (fish lipases and transglutaminases) will be recovered and investigated in transesterification reactions to incorporate useful biomolecules (e.g., omega 3 polyunsaturated fatty acids) in human foods for health benefits; and for transforming oils from fish processing discards into biodiesel as alternative fuel to reduce the dependence on fossil fuel. Fish transglutaminases will also be prepared and used to modify biomolecules to make them more resistant to degradation, and thereby facilitate the development of novel biomaterials for food and non-food uses. Such use of transglutaminases will be more acceptable to consumers compared with the use of chemicals to achieve simalar modifications in food products.
渔业是加拿大农业食品部门的重要组成部分,每年产生数百万美元的收入。然而,近年来鱼类资源一直在减少。这一事实加上海产品收获的季节性和原材料的高度易腐性,使得有必要开发更有效的程序来减少腐败,以确保产品可供人类消费。导致鱼品质迅速丧失的两个主要因素是微生物活性和内源酶的自溶。到目前为止,微生物引起的鱼类腐败已经得到了很好的研究,而自溶对腐败现象的影响研究得较少。这项拟议的研究将研究基于高压的新方法,并结合其他屏障,如天然抗氧化剂和低温储存,作为保存优质海鲜质量的工具。 海产品加工还产生大量目前没有得到高价值利用的废弃物。然而,废弃物富含有用的生物化学品,例如可以纯形式回收用于几种商业应用的酶。全球酶市场估计为每年13亿美元,每年增长率为12-15%。人们越来越需要发现新的酶来源以满足市场需求,而鱼类加工废弃物代表了一种未充分利用的资源材料,具有满足这一需求的潜力。在所提出的研究中,将回收两组鱼酶(鱼脂肪酶和转氨酶)并在酯交换反应中研究以掺入有用的生物分子(例如,在人类食物中添加ω 3多不饱和脂肪酸)对健康有益;以及将鱼类加工废弃物中的油转化为生物柴油作为替代燃料,以减少对化石燃料的依赖。还将制备鱼类转氨酶,并用于修饰生物分子,使其更耐降解,从而促进开发用于食品和非食品用途的新型生物材料。与使用化学品在食品中实现类似修饰相比,使用转氨酶将更容易被消费者接受。
