Abstract

The invention relates to low-salt soy sauce and a preparation method thereof. The low-salt soy sauce is characterized in that the salt content of the soy sauce is lower than 9g/100L; and furthermore, the amino acid nitrogen of the soy sauce is not less than 1.0g/100mL. The produced low-salt soy sauce does not utilize salt substitutes, has aromatic ester and sauce flavors, does not have other unpleasant odors, has delicious and mellow taste and is clear. The salt content of the low-salt soy sauce is reduced by nearly a half compared with that of the common commercial soy sauce, therefore the low-salt soy sauce is more wholesome to bodies.

Description

technical field [0001] The invention relates to a food, in particular to a seasoning low-salt soy sauce and a preparation method thereof. Background technique [0002] Soy sauce is an indispensable traditional fermented liquid seasoning in our daily life. It is fermented from soybeans and wheat. It is a condiment commonly used in both the East and the West. Most of the salt content in food is concentrated at 16-18g / 100mL, or even higher. Therefore, when consumers eat 20 grams per meal, the salt intake is more than 3.2g, which does not include the intake of all other salty foods. Therefore, the daily salt intake per person greatly exceeds the "safety line" of 6 grams recommended by the World Health Organization. This has seriously affected the further development of the soy sauce industry. At the same time, with the improvement of living standards, people's awareness of dietary health has been continuously strengthened, and consumers' excessive intake of salt has also attrac...
