Answer: Soaking method: Soak fresh ginkgo in clean water for about 7-10 days; pinch and step with hands to separate the outer seed coat and seed core (gingko); pack in a basket or sieve and rinse in running water Rinse and wash out the ginkgo; quickly dry in the sun or shade. Stacking method: Stack the ginkgo seeds for about 15 days, wait for the outer testa to rot and release water; separate the outer testa from the seed core (gingko) by pinching it with your hands and stepping on it; rinse and wash it in running water Take out the ginkgo and then dry it.

1. Soaking method

1. Fresh ginkgo needs to be soaked in water for 7-10 days, up to about 15 days, and then pinched with hands and stepped on to loosen the outer testa. Separate it from the seed core (gingko), put it in a basket or sieve and rinse it in running water to wash out the ginkgo.

2. To remove the core, you only need to find a toothpick, point the not-too-sharp end of the toothpick at one end of the ginkgo, and then pass it through the middle, and the ginkgo core will come out. This method can be washed out Ginkgo is white but contains a lot of water, so it needs to be dried quickly in the sun or in the shade.

2. Stacking method

1. First, stack the fresh ginkgo fruits for about 15 days, wait until the outer testa is ripe and water is released, and then squeeze the outer testa with your hands and step on it. Separate it from the seed core (gingko), put it in a basket or sieve and rinse it in running water to wash out the ginkgo.

2. Use a toothpick to remove the core. After removing the core, dry or air-dry the ginkgo. The ginkgo washed out by this method will be dry, but a few ginkgo with cracked outer testa will have black streaks, and There was a foul smell in the retting pile.

3. Beating in a stone mortar

After harvesting fresh ginkgo fruits, immediately put them into a stone mortar and hit them with a thick wooden stick. After the outer testa and middle testa are separated, rinse them in time and separate them. To remove the ginkgo, find a toothpick to remove the core, and then quickly dry it in the sun or shade. This method can be quickly put on the market, but it will be broken into 5-10 pieces, and the peeling will not be very clean, and there will be black spots on the surface of the ginkgo.

4. Mechanical peeling

Nowadays, peeling machinery has become more popular. Generally, mechanical separation and washing are performed on the basis of water soaking or retting, which replaces manual operation and not only reduces labor intensity. , and greatly improved work efficiency.
