1. Eye observation

South tofu is commonly known as water tofu, no water lines, no impurities, crystal white and tender is high quality; The bean curd with water lines, bubbles, fine particles and yellowish color is inferior.

North tofu is commonly known as old tofu. Its protein content is higher than that of water tofu. There are bubbles in the old tofu because the water and protein in the old tofu separate and flow out. That’s why it costs 2 yuan for a kilo of old tofu in the supermarket, because there is no water (if there are no bubbles, there is no water), You have to be careful that the boss adds food additives. I’m not denying the additives, but we try to eat less). Hot tofu will turn yellowish when it blows. It’s normal. Just look at whether the tofu section is smooth or not, in case of ginseng, bean dregs or other flour. Laoliu tofu is famous in Shehong, Sichuan. Authentic brine tofu, 30 years of quality, absolutely does not contain any other additives (except brine), we should try to eat natural food, the same day tofu eat the same day.

4. Gypsum tofu, some will have the feeling of sand, because gypsum is not too broken, not good for eating.
