1、鲟鱼片烟熏工艺优化及风味物质分析 摘要:优化烟熏鲟鱼片的生产工艺,并对其微生物、理化及风味物质进行分析。从烟熏温度(70~100℃)、烟熏时间(15~60min)和干燥时间(15~60min)对烟熏鲟鱼片生产工艺进行优化。结果表明:烟熏温度为85℃,烟熏时间为22min,干燥时间为22min时,产品感官评分最高。微生物及理化指标(水分、粗蛋白、粗脂肪、盐分、pH值、挥发性盐基氮、苯并芘、挥发性风味物质)研究结果显示:鲟鱼片烟熏后总菌数及大肠菌群显著减少,致病菌未检出;同时水分含量减少而粗蛋白、粗脂肪含量增加;产品苯并芘含量为0.24μg/kg;鲟鱼片
2、中风味物质由烟熏前39种增加到烟熏后60种,酚类物质增加最为明显,由烟熏前1种(0.89%)增加到烟熏后9种(12.90%)。 关键词:鲟鱼;烟熏;风味物质;加工工艺;苯并芘 Abstract:Theproductionofsmokedsturgeonfilletswasstudiedandtheproductionparameterssmokingtemperature,smokingtimeanddryingtime,rangingfrom70?C100℃,15?C60minand15?C60min,respectively,wereoptim
