海洋中蕴藏丰富的生物资源,有着许多结构新颖、作用特殊的活性多糖。我国贝类资源丰富,品种繁多,扇贝、鲍鱼、贻贝、牡蛎、菲律宾蛤仔、青蛤等产量均居世界前列。这些海洋贝类富含活性多糖,具有抗衰老、抗肿瘤、抗病毒、提高免疫力、降低血糖、血脂、血压等多种生物学活性,因其很高的营养价值和保健功效,已成为目前全球研究和开发的热点。研究海洋贝类多糖的提取、分离和纯化技术,分析其结构、生物活性和构效关系,能够实现海洋贝类资源高值化利用,同时,积极推进海洋生物产业和健康产业的发展。本文对海洋贝类多糖的提取、纯化、结构与活性方面的研究现状进行了综述,并进行了展望,旨在为海洋贝类资源的高附加值开发提供理论支持。 相似文献

我国海洋生物资源丰富,海产品加工业发展较快,鱼、虾、贝类等加工过程中产生大量的副产物,造成资源的严重浪费以及环境的污染。许多海产品加工副产物中含有丰富的磷脂,海洋磷脂由于含有丰富的二十二碳六烯酸(DHA)和二十碳五烯酸(EPA)等多不饱和脂肪酸侧链而具有极高的营养价值,将这些磷脂成分进行高值化利用对减少资源浪费、降低企业成本、增加企业经济效益、改善生态环境等均具有非常重要的意义。综述了海产品加工副产物来源磷脂的提取制备、成分分析及生物活性等方面的研究进展,以期为海产品进一步的综合利用和精深加工提供一定的理论参考。 相似文献

Food industries produce huge amounts of processing waste that are often disposed of incurring expenses and impacting upon the environment. For these and other reasons, food processing waste streams, in particular marine processing waste streams, are gaining popularity amongst pharmaceutical, cosmetic and nutraceutical industries as sources of bioactive molecules. In the last 30 years, there has been a gradual increase in processed marine products with a concomitant increase in waste streams that include viscera, heads, skins, fins, bones, trimmings and shellfish waste. In 2010, these waste streams equated to approximately 24 million tonnes of mostly unused resources. Marine processing waste streams not only represent an abundant resource, they are also enriched with structurally diverse molecules that possess a broad panel of bioactivities including anti‐oxidant, anti‐coagulant, anti‐thrombotic, anti‐cancer and immune‐stimulatory activities. Retrieval and characterisation of bioactive molecules from marine processing waste also contributes valuable information to the vast field of marine natural product discovery. This review summarises the current use of bioactive molecules from marine processing waste in different products and industries. Moreover, this review summarises new research into processing waste streams and the potential for adoption by industries in the creation of new products containing marine processing waste bioactives. © 2015 Society of Chemical Industry 相似文献

Many commercially important shellfish are filter feeders and, as a consequence, concentrate microbes from the surrounding waters. Shellfish may be relayed or depurated to reduce the level of microbial contamination, but the efficiency of these purification practices, particularly in relation to viruses and indigenous marine bacteria, is questionable. Therefore additional processing is necessary to ensure the safety of shellfish for human consumption. In recent years high pressure (HP) processing has been investigated as an alternative method for food preservation. HP technology allows inactivation of microorganisms while maintaining sensory and nutritional properties of foods. Currently, HP processing has several commercial food applications, including oysters. As well as enhancing safety and extending shelf-life, HP treatment has the additional advantage of shucking or opening shellfish, making this technology particularly beneficial to the shellfish processing industry and consumers alike.Industrial relevanceHigh pressure (HP) processing is increasingly being used in the commercial processing of oysters, due to its minimal effects on sensory and nutritional quality, the opening or shucking of oysters during treatment, and the reduction of levels of Vibrio vulnificus, a pathogen of concern particularly in the US. However, little is known of the efficacy of HP treatment in reducing other pathogens in shellfish such as human enteric viruses, which are the predominant cause of shellfish-borne disease. This article reviews the inactivation of microorganisms of importance to shellfish, particularly viruses, the commercial HP processing of oysters and the advantages of HP technology as they pertain to the seafood industry. 相似文献
