Product and process characteristics
1, Muqianzhang has a unique flavor and is famous for its freshness, fragrance and lightness. It is a good product in bean products. The technological process of making thousands of pine summer molds is: soaking high-quality soybeans, grinding them into pulp with a stone mill, then boiling fresh soybean milk with slow fire, beating flowers with brine (instead of gypsum), and then pouring them on the coarse cloth laid in advance to dry the water.

Put clean indica rice straw at the bottom (japonica rice straw, glutinous rice straw and plastic film are not allowed), press a bean board on it, put it in a warmer place, and eat it after it is moldy.
3. Thousands of "Songxia" molds have been sterilized at high temperature, and the hygiene indicators are strictly in accordance with GB27 12. They are vacuum packed in clean and dry plastic bags. Cold storage above zero, shelf life 120 days.
Matters needing attention in processing
1, acidification is the key process, and it is necessary to make the acidification of thousands of tablets uniform. The non-acidified part is easy to breed corrosive bacteria, which makes the product have a strong ammonia smell.
2. The moldy thousand pieces are made of hot soybean milk. protein has been denatured, so you don't need to cook them before they become moldy.
3. Mo Qian, a wild Mucor from Zhangwei biological system, has no aflatoxin B 1, just like moldy bean dregs, which meets the national food hygiene standards. Even so, it is best to use artificially inoculated pure culture Mucor.
