ABSTRACT: The aim of the present study was to clarify by means of sensory tests whether taste, aroma, or texture is the dominant contributor to people's ability to identify the animal species of meat. The meat samples used were loins of beef, pork, and lamb; chicken thigh; and aigamo (crossbreed of domestic duck and wild duck) breast. Panelists (32 to 35 persons) wearing eye masks ate cooked pieces, patties, and heated soups prepared from the meats of these 5 species with and without pinching their noses to regulate the aroma sensation, attempted to identify the species, and gave reasons for their identifications. In the test involving meat pieces and pinched noses, the percentage of panelists identifying chicken correctly was the highest, at 72%, whereas the percentages of correct identification for all other animal species were less than 50%; however, values were higher for each species in tests without nose pinching. In the tests of meat patties involving pinched noses, the percentage of correct identification for each animal species was slightly lower in comparison with the tests of meat pieces; however, the values were higher in tests without pinched noses. In the tests of soups using pinched noses, the percentage of correct identification for each animal species was lower than 30%; however, the values were higher in tests without pinched noses. These results led us to the conclusion that aroma is the most important contributor to the identification of the animal species of meat, and texture is the 2nd most important contributor. The contribution of taste appears much smaller than that of aroma and texture. 相似文献

近年来随着人们对身心健康、环保及美味食品的追求,我国肉类农产品的供求出现了严重的不平衡及波动。欧美等国已经投入大量资源开展人造肉研究,预计未来可能将对我们国的食品及肉制品市场造成很大的影响。所以将人造肉来替代我们传统肉类的产品,首先需要能够提供肉的美味和营养,还要给生态能源、环境等带来可持续性发展。人造肉主要分为两种:一种是通过植物蛋白及其他植物性成分合成的植物人造肉,另外一种是通过动物干细胞合成的细胞人造肉。但人造肉目前仍存在较多的技术、安全以及成本等方面问题。该文对人造肉的研究现状和存在的问题进行综述,以期对我国人造肉及相关领域研究提供参考。 相似文献

热鲜肉与冷却肉品质差异之管见 总被引:3,自引:0,他引:3
我国肉与肉制品中生鲜肉占比约80%,生鲜肉中热鲜肉占比约60%,而冷却肉占比不足30%。近年来研究表明,僵直前的热鲜肉更适合炖煮、炒制、涮制等传统烹饪方法,而解僵成熟后的冷却肉则更适合烘烤、烧烤等西式烹饪方法。基于热鲜肉和冷却肉各自不同的加工特性和优劣势,本文在综述热鲜肉与冷却肉品质研究最新进展的基础上,提出了建立适合我国消费者饮食习惯、个性化消费需求和精细化烹饪方式的生鲜肉加工理论、技术、标准与管理体系,以期为生鲜肉生产“定制化”新业态提供技术和理论支撑。 相似文献
