摘要
不同厂家生产的广式腊肉在水分含量、水分活度和挥发性风味成分方面都有较大的差别,水分含量与水分活度之间并没有显著相关性,保质期与水分活度相关,与水分含量没有明显的相关性,水分活度越低,保质期越长。在3个样品中具有相同挥发性风味成分35种,约占总挥发性成分的60%左右,而且成分的相对质量分数差别很大。醇类物质、醛类物质和酯类物质是广式腊肉重要的挥发性风味物质,在广式腊肉风味的形成中起着关键性作用。
In this study, Cantonese-style bacons from different manufacturers varied substantially in water content, water activity and volatile composition. There was no significant correlation between water content and water activity. Shelf-life was related to water activity but had no obvious correlation with moisture content; the lower the water activity, the longer the shelf life. Three samples were tested and 35 identified volatile flavor compounds were common about 60% of the total volatile components, with their relative contents greatly varying among the different samples. Alcohols, aldehydes and esters were the main volatile flavor compounds and played a key role in the formation of flavor in Cantonese-style bacon.
