鱼香肉丝方便菜肴生产工艺优化及挥发性风味成分鉴定

Optimization of Production Technology and Identification of Volatile Flavor Components of Yuxiang Shredded Pork

  • 摘要: 为了优化鱼香肉丝方便菜肴配方,并探究其最佳灭菌条件和储藏方式、鉴定挥发性风味成分,通过单因素试验及正交试验探究辅料添加量对菜肴品质的影响,探讨不同灭菌条件及储藏方式对产品汁液流失率、色差、菌落总数、挥发性盐基氮、pH、丙二醛含量、感官评分的影响,采用顶空固相微萃取−全二维气相色谱−质谱联用技术研究挥发性成分,最终优化得到产品配方(以里脊肉100 g计):蒜添加20 g,醋添加4 g,泡椒添加20 g,糖添加8 g,盐添加1.2 g。最佳灭菌工艺:121 ℃,灭菌15 min。储藏期:−18 ℃条件下储藏15 d。共检测到136种风味化合物,其中含量较高并且对风味有重要贡献的化合物有α-姜黄烯、(反,反)-2,4-癸二烯醛、反-2-己烯醛、反-2-辛烯醛、反-2-癸烯醛、4-乙基-2-甲氧基苯酚、3-乙烯基-1,2-二硫代环己-4-烯、二烯丙基二硫、二烯丙基硫醚、二烯丙基三硫醚。本研究为鱼香肉丝方便菜肴工业化生产及其风味评价提供了一定的理论依据。

     

    Abstract: In order to optimize the formula and explore the best sterilization conditions and storage methods of shredded pork with garlic sauce, a single factor and orthogonal experiment with juice loss rate, L*a*b* value, aerobic plate count, total volatile base nitrogen, pH, malondialdehyde determination combined with sensory evaluation were used. Besides, the volatile flavor compounds were studied by HS-SPME-GC × GC-MS and electronic nose. As a result, the optimized product formula (in terms of 100 grams of tenderloin) are as below: 20 g garlic, 4 g vinegar, 20 g pickled pepper, 8 g sugar and 1.2 g salt. The best sterilization process is sterilizing with autoclave at 121 ℃ for 15 minutes. In addition, the storage period is 15 days at −18 ℃. A total of 136 compounds were identified, including compounds with high content that may importantly contribute to its “Yu Xiang” flavor: α-Curcumene, (E,E)-2,4-decadienal, (E)-2-hexenal, (E)-2-octenal, (E)-2-decanal, 4-ethyl-2-methoxyphenol, 3-vinyl-3,6-dihydro-1, 2dithiain, diallyl disulfide, diallyl sulfide, diallyl trisulfide. The results of this study provide a theoretical basis for the industrialized production and flavor evaluation of shredded pork with garlic sauce.
