1, fruit ripening: first put the ripe apples or bananas and green mangoes into a plastic bag, tie the bag tightly, and then put it in a warm place, and it will ripen in about 2-3 days. This is because mature fruits will release ethylene, while green mangoes will accelerate ripening by absorbing ethylene.

2. The rice is ripe. Put the green mango in the rice and cover it with rice. It will be cooked in about 3-4 days. This is because rice will release some ethylene during storage, and ethylene is an important substance to ripen green mangoes.

3. High temperature ripening. If it is in summer, you can put the green mango directly on the balcony, and the high temperature in summer will make the green mango mature itself; If it is winter, wrap the green mango and cover it in a place with high indoor temperature. If the green mango is very green, you can cover it with ripe bananas or apples. Green mangoes in winter need at least 3-4 days to ripen.

4. Drug ripening. Ethephon is one of the most commonly used ripening drugs. It can be diluted and sprayed directly on the surface of green mango, and then covered with some items, and it can be ripened in about 2 days.

5. It should be noted that when green mangoes are ripened, don't touch the water vapor, so as not to cause the peel to fester. Remember to add a little paper to absorb water vapor when covering green mango in winter, and check whether it is ripened every day. As long as it feels soft when pressed, it means it is cooked. Mature green mangoes should be eaten in time, not for too long.
