[how to accelerate ripening of kiwifruit] the method of ripening kiwifruit

Kiwi fruit is a fruit that many people like to eat, but many of the kiwi fruits that have just been bought are hard and sour to eat. Experts remind kiwi fruit must be cooked before eating, otherwise some of the substances are not conducive to human health, while astringent taste is also very difficult to eat. At this time, we need to master some scientific kiwi ripening methods, so that we can enjoy mature kiwi in the shortest time. Specific ripening methods: kiwi fruit and ripe apples, bananas, tomatoes and other fruits can be stored together, and the natural ripening gas "ethylene" emitted by these mature foods can be used to ripen.

How does kiwi fruit ripen?

How to ripen kiwi fruit is actually very simple. As long as the apple, banana or pear and kiwi put a plastic bag tightly, after two days kiwi soft ripe, the effect is very good. Because bananas, apples and pears release a substance called ethylene, which has a strong ripening effect, kiwi fruit ripens quickly.

Ripening kiwi fruit with toothpicks

Wash the kiwi fruit with water first, then use a clean toothpick to make a few small holes in the kiwi fruit, then put it in a plastic bag, tie it up, and place it for a few days, which will speed up the ripening progress. You can also use a knife to make a few small cuts on the outside of kiwi fruit, which can also play a role in ripening kiwi fruit. That's because small cuts allow kiwi fruit to produce ethylene, which speeds kiwi ripening.

Warm reminder: although this method is good, but small wounds will breed some microorganisms, will affect the quality of kiwi fruit, so it is not recommended to use.

Increase the ambient temperature of fruit.

The higher the environmental temperature of kiwifruit storage, the more active the metabolism of fruit, the faster the ripening. Therefore, it is best not to put the raw kiwi fruit just bought in the refrigerator, put it in the box at normal temperature for a day or two, and the softening speed will be faster than that stored in the refrigerator.

Warm reminder: placed at room temperature kiwifruit, relatively easy to breed bacteria, so storage must always pay attention to observe the appearance of kiwifruit, prevent decay and deterioration. When eating kiwi fruit, it should be peeled and eaten.

sealed ripening

A method for rapidly ripening kiwi fruit in large quantities includes such steps as packing kiwi fruit into cardboard box, stacking the box indoors, closing door and window, controlling humidity to 80-90%, and controlling temperature to 20-30 deg.C, opening the box every 2-3 days, releasing carbon dioxide, and allowing oxygen to enter the box, and turning over the stack. Kiwifruit hard fruit 5-8 days can be fully ripened, to achieve the best edible flavor.

immediately open that fruit box after ripen the kiwi fruit, opening indoor doors and windows for cool and ventilation, reducing ethylene gas content generated during ripening of the kiwi fruit, storing the ripened fruit for 3-4 days at 20 DEG C, and storing for one week at 0-5 DEG C.

Is apple ripening kiwi reliable?

Is apple ripening kiwi reliable? Let's look at a set of experiments:

1. Experimental equipment: kiwi fruit, apple, food bag.

2. Objective: To compare the effect of kiwi fruit alone and with apple.

Third, the experimental process: hard kiwi fruit and apple with the same place, 7 days later soft.

I bought 4 domestic kiwi fruits for more than 4 yuan a catty from the supermarket. When I first bought it, kiwi fruit was hard and inedible. Salesman said, kiwi soft not easy to transport, easy to damage, so into the supermarket stores are generally hard. The reporter put 2 kiwi fruits together and sealed them with food bags. Then, place another kiwi with a ripe apple and seal it with a food bag. Subsequently, the reporter placed two bags of fruit in one place and continued to observe their changes.

After 7 days or so, the reporter found that the kiwi fruit placed with the apple has obvious signs of softening, while the change of the kiwi fruit put together by the two kiwi fruits is not very big. Peel two bags of kiwi fruit to see, and apple with the kiwi fruit flesh color is darker, taste better, while two kiwi fruit together appears a little green, eat in addition to hard, but also a little sour.

How to buy kiwi?

Look at the hardness.

Carefully touch the fruit all over the body and select the harder fruit. Any fruit that has become soft as a whole or partially soft, try not to. If you choose, eat it immediately after you go home.

look at the appearance

Full-bodied, non-wounded and disease-free fruit is better, and the part near one end is best if it is faintly green. The number of epidermal burrs varies according to the variety.

Look at the size.

Small fruits are not inferior to large fruits in taste and nutrition, so there is no need to blindly pursue large fruits, let alone unusually large fruits.

look at the color

Kiwi fruit with thick green flesh and sweet and sour taste has the best quality and the highest vitamin content. The flesh color is lighter and slightly inferior.
