Vegetable seasoning powder rich in isothiocyanate and production method thereof
Technical Field
The invention relates to vegetable seasoning powder rich in isothiocyanate and a production method thereof, belonging to the technical field of deep processing of food.
Background
The cruciferous vegetables contain high content of nutrients and active substances such as vitamins, minerals, dietary fibers, anthocyanins, polyphenols, carotenoids, glucosinolates, etc. The frequent intake of cruciferous vegetables is helpful for preventing various cancers such as liver cancer, gastric cancer, lung cancer, bladder cancer, breast cancer, prostatic cancer, pancreatic cancer, leukemia and the like, and is mainly due to the function of isothiocyanate generated by glucosinolate under the action of myrosinase. In addition, the isothiocyanate has the effects of sterilization, oxidation resistance, cardiovascular disease prevention, inflammation elimination and the like.
The broccoli, cauliflower, common head cabbage, Chinese cabbage, pakchoi, rape, radish, mustard, rape and the like are wide in cultivation areas in China, have high yield and are vegetables which are popular and frequently eaten by consumers. However, the presence of epidermal specific sulfur protein (ESP) hydrolyzes glucosinolates toward nitriles, thereby reducing the formation of isothiocyanates having an anti-cancer effect, and thus, increasing the glucosinolate content and the activity of myrosinase as well as decreasing the activity of ESP protein increases the amount of isothiocyanates formed. In addition, since most vegetables are eaten after cooking, which reduces or even inactivates myrosinase activity, and intestinal microorganisms have limited degradation of glucosinolates, development of isothiocyanate-rich products is important for human health.
