Abstract

The invention relates to edible spice lenthionine. The lenthionine comprises the following raw materials in part by weight: 18 to 20 parts of sodium tetrathiocarbonate, 18 to 20 parts of diiodomethane, 140 to 160 parts of absolute ethyl alcohol and 90 parts of carbon tetrachloride. The lenthionine (also named 1,2,3,5,6-pentasulfide cycloheptane) prepared by the invention is widely applied to sauce products, meat products, convenient food and seasoning bouillon series, has pure, true and strong flavor, rich meat and good taste, can cover bad peculiar smell and resist to high temperature, is an ideal option for canned mushroom, mushroom sauce, the convenient food and seasoning and has a wide market prospect.

Description

technical field [0001] The invention belongs to the field of fine chemical industry and relates to edible spice mushroom essence, that is, 1,2,3,5,6-pentathiacycloheptane. Background technique [0002] In today's society, people's choice of food is becoming more and more colorful. In addition to caring about their nutritional value, they also pay great attention to their color, aroma and taste. Therefore, the demand for edible spices is increasing day by day. Shiitake mushroom is one of the internationally recognized health vegetables, which can improve human immune function. Lentinus edodes 1, 2, 3, 5, 6-pentathiocycloheptane is the main aroma component of Lentinus edodes. It is the first organic compound containing multiple sulfur atoms obtained from nature. It has a strong characteristic aroma and good antibacterial activity. and biological activity have aroused great interest. However, the traditional method for synthesizing 1,2,3,5,6-pentathiacycloheptane has harsh r...
