A Voice-of-Consumer Approach in Development of New Seafood Product Concepts

This article describes a consumer-based approach for development of new seafood product concepts among young adults in Norway and Iceland. The study aim was to gain insight into how young adults determine their acceptance of seafood and make potential product choices. Additional insights measured were confidence in seafood preparation and consumption choices when exposed to specific new seafood concepts. Based on consumer-reported values, three seafood product concepts were evaluated by 354 consumers in a web-based, conjoint experiment in Norway and Iceland. Consumers' evaluations showed a number of consumer preferences for specific seafood product concepts partly associated with and partly conflicting with their original values. Understanding consumer attitudes can help to explain these results. The results of this study will be used as a guide for the next step in developing seafood product concepts.

膜分离技术在水产加工中的应用

膜分离技术是 2 0世纪 60年代发展起来的新型分离单元操作。由于它在分离物质过程中具有不涉及相变、无二次污染、结构紧凑、易于自动化操作等诸多优点 ,发展相当迅速 ,被国际上公认为 2 0世纪末至2 1世纪中期最具有发展前途 ,甚至会导致一次工业革命的前沿技术 ,现已成为世界研究的热点[1,2 ] 。目前 ,膜分离技术最多应用在工业水处理和海水淡化等方面 ,在食品工业中也得到广泛应用[3～ 5] 。膜分离技术应用于水产品加工业的优越性主要有 :1 分离过程在密闭系统中、常温下即可进行 ,无相变 ,过程避免和减轻了热和氧对风味物质和营养成份的…     

Survey of Listeria monocytogenes in New Zealand Seafood

A Survey was carried out on oysters and mussels collected from three different areas of New Zealand for the presence of Listeria monocytogenes and fecal coliforms. Three samples of oysters contained L. monocytogenes. Fifty-two samples of processed seafood purchased from retail outlets were tested for L. monocytogenes before their designated use-by dates. Eighteen samples (35%) contained L. monocytogenes. These were cold-smoked salmon, hot-smokes squid strips, cold smoked blue cod fillet, smoked eel fillets and hot-smoked mussel samples. It was concluded that contamination of the processed seafood occurred during processing rather than form the aquaculture sites.

By-Products and Seafood Production in Japan

Japanese output of fishery products in 1993 amounted to 8.7 million metric tons valued at 2.5 trillion yen, and has gradually decreased for the last five years. Annual imported fishery products in that year amounted to 3.1 million metric tons (1.6 trillion yen). Prawn, tuna, salmon, mackerel and cod were the most prominent fishes imported mainly from the US, Taiwan and Republic of China. These accounted for 40% of total imports. A Japanese self-supplying rate for fishery products was about 64% in 1993. Under these severe conditions surrounding the fisheries of Japan, the Government operates several projects to develop increased utilization of initialized aquatic natural resources and to increase the value of marine products. These include better utilization for human consumption of initialized flying squid, headlight fish and low-quality spawned salmon; development of a large-scale extraction and purification technology for docosahexaenoic acid from marine products; and development of novel seafood by using high hydrostatic pressure technology. For the topics of by-products from aquatic resources, products from chitin and chitosan, fish oils, both for medical and food uses, liquid crystal, protamines from fish testicles for antibacterial for foods, growth hormones for fish farming, and several pharmaceutical compounds from marine organisms are introduced.

Functions and Uses of Phosphates in the Seafood Industry

Food-grade phosphates have many functional uses in seafood products, including, but not limited to, the retention of moisture and flavor; the prevention of lipid oxidation; shelf-life extension and cryoprotection. Condensed phosphates such as, sodium tripoly- and hexameta- phosphates and blends are most often used. Information on the uniform and consistent application of phosphates to seafood products is generally lacking and the process protocol in many seafood plants is often derived empirically. Abuse of phosphates leads to dramatic increases in the ratio of water to protein and charges of economic fraud. The objective of this work is to summarize previous efforts related to the responsible application of phosphates to seafood products.

Quality Issues in the Danish Seafood Industry

Abstract

A questionnaire on quality management and measurement issues was conducted in the Danish seafood industry. The aim of the survey was to investigate to what extent the industry uses quality management systems, and which measurement methods are used. The results showed that the mandatory Own Check Systems, EU directive no. 91/439, were very well established. However, the application of more comprehensive systems was only found in 4% of the participating companies. Characteristics common to these companies were a high export rate, over 100 employees, and high turnover. The survey demonstrated that the measuring and control methods utilized by companies were mainly directed at controlling temperature, weight, sensory aspects, and microbes.
