Avocados are green when you buy them, do you have to wait until they turn black before you can eat t

If you're not afraid of hard.

Once you buy it, you can eat it.

But I used to wait until he was a little softer to the touch.

It's more delicious this way.

And I like to eat it with sugar or honey.

Generally speaking, if it is soft, the outside color is indeed darker.

But there are also different varieties.

I don't know if you're eating other types I've seen.

If the surface is uneven to the touch.

I recommend waiting for him to soften before eating.

If it's the kind with a smooth surface.

In general, it can be eaten.

But I don't think it's tasty.

It is advisable not to eat avocados that have been cut overnight. Avocados must be eaten fresh, not for a long time, otherwise they will soon oxidize and turn yellow, so the best thing to do is to eat them as soon as possible, and the remaining avocados will easily deteriorate and change their flavor if they are not taken effective measures for a long time.

If the avocado is cut or half left, then it is only necessary to put it in the refrigerator, but there are two points to pay attention to when storing: one is to leave the pit in the pulp (the antioxidant capacity of the pit is much stronger than the pulp), and sprinkle some lemon juice to prevent the pulp from being oxidized too quickly, and seal it with plastic wrap; The second is to ensure the appropriate temperature in the refrigerator refrigerator, generally suitable for the storage of avocados between 4 8, but the storage time of avocados that have been cut should not be too long, it is recommended to eat as soon as possible.

Hard avocados can sit for a long time. If you buy a hard avocado and want it to soften quickly, place it in a warm place. If you want to delay softening, keep it in a cool place or in the refrigerator.

Ripe avocados (avocados) can be stored in a vegetable box in the refrigerator for about a week at room temperature.

The flesh of the avocado (avocado) tends to turn black when exposed to air. If you only use half at a time, be sure to keep the core half, do not remove the core, sprinkle with lemon juice, wrap it in plastic wrap, and put it in the refrigerator. If it is to grow seeds, it should not be frozen, because avocados are tropical plants, and below 0, the seeds will lose their ability to germinate.

If you just want to eat the pulp, you can freeze it, but after thawing, it doesn't taste as good as fresh.

The discoloration is oxidized and can be eaten, but bacteria will be produced overnight.

Why does fruit oxidize when cut:

The discoloration reaction occurs mainly due to the presence of phenolic compounds in these plants. For example: polyphenols, catechols, etc.

Phenolic compounds are easily oxidized to quinones, that is, they change color and turn yellow, and the color gradually deepens with the increase of the amount of reaction, and finally turns dark brown. The oxidation reaction occurs due to the contact with oxygen in the air and the release of phenol oxidase in the cell.

Phenolic oxidase exists in organelles and cannot come into contact with phenolic compounds until the tissue is damaged, and oxygen in the air cannot enter, so no oxidative discoloration reaction occurs. When the cell tissue is damaged, phenol oxidase is released to contact with phenolic compounds, catalyzing the oxidation of phenolic compounds, coupled with the action of oxygen in the air, a discoloration reaction will occur. Among them, polyphenols can be directly oxidized to quinones and change color.

Catechol molecules, on the other hand, polymerize under the action of phenol oxidase. Two catechol molecules are linked together to form catechol dimers, which in turn can be joined in pairs to form tetramers. The individual catechol molecules and their dimers and tetramers are all colorless, but catechol tetramers can form multimers, which are purple.

So the more polymers are formed, the darker the color of the incision surface will be.

It's okay, it's just that the phenols in the fruit are oxidized into quinones by the air.

It can be eaten, but the discoloration of the fruit is just oxidized, and some experts also believe that this will reduce the nutritional value of the fruit. However, I think that the fruit should not be eaten after being cut for a long time, not because of the discoloration, but because there is an incredible amount of bacteria on your knife (if you bite it, on your teeth), which will attach to the flesh of the fruit (that is, the endocarp of the pear), and after a night of breeding,,, why eat it. Hope that helps (personal insight).

Do not eat it, lest you have diarrhea

Avocado is also commonly known as avocado, it is a fruit imported from South America, and the unit price is still relatively high in the early days, because there are very few such fruits in China, and now it has become a relatively popular fruit. It is also known because it tastes very much like cream and meat, which may be a little unaccustomed at first, but after a long time, you will be attracted to its taste. MoreoverIt is a low-fat, low-carb, high-protein food that is perfect for a ketogenic diet.

The ketogenic diet is currently one of the more popular ways, but it is not suitable for everyone, if there is no big problem with the body's functioning, it can be used in this way. Avocado is an ingredient that is often seen on the ketogenic dietIt can be eaten raw or tossed with salads, and it tastes and textures great. Some people have even studied a special way to eat it, which is to dip raw cut avocado in soy sauce, which has a taste very similar to Japanese salmon.

A normal avocado has a dark green flesh when cut, and then the flesh will be softer and have a very dense texture, which is just ripe avocado. SometimesIf the avocado is left for a long time, when you cut it, you will see that it has brown fibers, or that its brown area is a little large, but the taste has not changed at this time, and it is actually edible. If the avocado has been left for too long, the whole skin has turned black, and the whole flesh has turned brown and pureed when cut, it can no longer be eaten.

Overripe avocados are actually no longer nutritious, and the taste is also very poor, so it is recommended not to eat them.

Avocado as an imported fruit, now more and more well-known, eat a little avocado every day, especially for girls is very good, but because it is also a high-protein fruit, eating too much will not only cause indigestion, but also increase weight and cause obesity, is to eat 1 to 2 avocados per week is more appropriate, but also to subtract the amount of staple food, so as to achieve a balanced effect.

If the avocado is brown inside, it is actually not allowed to be eaten, because it means that its flesh has deteriorated and may be harmful to the human body.

You can't eat it. Because the inside is usually white, if it is brown, it may have deteriorated or expired. So don't eat it.

The inside is brown, it should have been moldy, and there are a lot of germs after the mold, and you can't eat it anymore, and there will be a lot of aflatoxin.
