First of all, He Qian's soy sauce is zero-added, and its umami flavor is naturally fermented, which is different from soy sauce with monosodium glutamate. He Qian's zero-added soy sauce has a natural bean flavor, which can both refresh and mask the taste of the food itself, unlike some soy sauces that turn into liquid monosodium glutamate. Secondly, although monosodium glutamate is not added to He Qian soy sauce, amino acid nitrogen is still high. For example, the amino acid nitrogen of He Qian's 380-day product reaches 1.2g/ 100ml, which is very high among the zero-added products on the market, so it tastes delicious.
