How to avoid black hair to make tofu milk?

Mildew tofu has black hair in the fermentation process, and the black one should be Aspergillus Niger, which can mainly cause mildew and deterioration of grain, food, grain, fruits and vegetables with high water content. You'd better not eat it. If the conditions are not well controlled, it may be toxic.

The production method of bean curd can refer to the following steps:

Ingredients: 4 kg of tofu, 4 teaspoons of salt, 8 teaspoons of Chili powder.

Accessories: appropriate amount of straw.

1. Drain the water tofu (preferably gypsum tofu, which is hard and moldy) for a day or so (be sure to air dry the water, otherwise the moldy tofu will not only collapse, but also grow green hairs and black spots, and the mold will go bad).

2. Spread some clean straw on the ground, break the tofu into small pieces, put a layer of tofu and a layer of straw according to the good pattern, and finally seal it. If the weather is warm, it will take 4 to 5 days. In the weather around 3 degrees, I let it go for 2 weeks.

3. Wait for the tofu to grow Mucor rubrum.

4. Add salt to the Chili powder, mix well, roll the moldy tofu pieces in the Chili powder dish a few times, so that all sides are stained with Chili, and then put them in a sealed jar for a day or two to eat.
