the main components of green mustard are horseradish, which is a perennial erect herb in Cruciferae, also known as sunflower and horseradish. Originated in eastern Europe and Turkey, it has been cultivated for more than 2 years. China's suburbs of Qingdao and Shanghai were cultivated earlier, while other suburbs or vegetable processing bases have a small amount of cultivation. It is a kind of seasoning vegetable, which is mainly exported after fresh-keeping or processing dehydration, and is well received by consumers in Japan and European countries. The root has a special spicy taste and contains allyl thiocyanic acid (C3H5CNS). After grinding, it is dried and stored as a seasoning for boiled beef and creamy food, or sliced into cans for seasoning. China has been used as a medicine since ancient times, which has diuretic and nerve-exciting effects. Modern research shows that it also has a strong anti-cancer effect.

Horseradish is a rare green plant, which contains natural glucosinolates. When the glucosinolates meet with water, they are enzymatically catalyzed by glucosinolates at a certain temperature, acidity and the action of glucosinolates, resulting in allyl isothiocyanate, a bactericidal and bacteriostatic functional factor. Allyl isothiocyanate can effectively kill and resist bacterial infection, inhibit its growth and reproduction, and has strong lethality to various bacteria in seafood products, and can kill cholera bacteria. Eating often won't be harmful to human body, but don't overdo it, and the best things will be counterproductive.
