英文摘要:

      The volatile sulfides in cheese mainly include methanethiol, hydrogen sulfide, dimethyl sulfide, dimethyl disulfide, methional, etc., which are important odorants of cheese and make key contributions to the formation of cheese flavor. In this study, a systematic review of the composition and flavor contribution of volatile sulfides in cheese was carried out based on relevant literatures, the common methods for the determination of volatile sulfide in cheese and their advantages and disadvantages were introduced. The formation mechanism and the biosynthesis regulation strategies including strain screening, microbial collocation and combination, and genetic engineering technology were summarized. Finally, the problems existing in the current issues and future research directions were also summarized and forecasted. It provides a theoretical basis for the comprehensive cognition of the volatile sulfide and their formation and regulation in cheese, and the development of cheese which are more suitable for Chinese consumers and the transformation and upgrading of the cheese industry in China.
