速冻调理专用YE产品的开发和应用研究

Development and application of quick frozen conditioning special YE products

酵母抽提物(Yeast Extract,YE)是以可食用的酵母为主要原料,采用生物酶解等技术制成的一类天然风味物质,其富含大量的呈味氨基酸、肽类、核苷酸等酵母细胞中的可溶性成分,具有鲜味丰富,口感醇厚,天然营养的特点。速冻调理产品是肉制品中重要的产品类型,其采用速冻工艺,并在冻结状态下(产品中心温度在-18℃以下)贮存、运输和销售,产品经解冻后香气、厚味等是评价其品质的重要指标之一。本文通过对速冻调理专用型YE进行了开发,并对其在调理产品中的应用进行了研究,结果表明:速冻调理专用型YE能延长香气的滞留时间,增加产品的厚实口感,对速冻调理产品的整体风味的提升具有较好的协助作用。

YE, a class of natural flavoring substance were made from edible yeast by biological enzyme technology, contained a large number of soluble components in yeast cell, such as amino acids, peptides, nucleotides, and have the features of rich flavor and mellow taste, and natural nutrition. Quick frozen con- ditioning product is an important type of meat products. Through quick - freeze process, they were stored, transported and marketed in the frozen state （ product center temperature below - 18 ℃ ）. The flavor and atsumi after thawed were one of important indicators to evaluate its quality. The quick frozen conditioning special YE product and its application in conditioning products were studied in this article. The results showed that the flavor of quick frozen conditioning special YE could extend the residence time, increase at- sumi, and had a good assistance to enhance the overall flavor of the frozen - products.
