“Is it better for fruits to be sour or sweet?” “Is anti-seasonal fruit harmful to health?” “Can I still eat the ones that are a little bit bad?” In life, I believe many people have had similar questions. Ben the following are 6 questions about fruit.
1, pick the fruit, the color, or smell the aroma of the fruit varieties are different, the color will be different, such as Fuji apples are red, Wang Lin apples are yellow. After the fruit is bagged, the color will be more beautiful and uniform, but the taste of those unevenly colored fruits is not inferior to the beautiful fruit. From a delicious point of view, it is more reliable to smell the aroma to pick fruits, regardless of the color, the fruits with strong aroma are usually the most delicious. However, in terms of nutritional value, the darker and more intense varieties are usually better than the lighter ones, for example, the antioxidant substances in the purple-black and purple-red varieties of grapes are higher than the green and white flesh varieties.
2, judging from the taste of the fruit, sour ones have high nutritional value or sweet ones The content of nutrients and health components of fruits has little to do with sweetness. Generally speaking, for the same kind of fruit, the variety with slightly sour taste has a little higher content of vitamins and antioxidant components. For example, citrus that is particularly sweet and has no sourness at all has a somewhat lower content of polyphenols than the slightly sour tasting variety. This is because most health ingredients are somewhat unpleasant, either sour, astringent, or bitter, basically unrelated to sweetness. Here is not to say that the fruit is sweet is not good, is to say that if only sweet, no other flavor, health value may not be as strong as the flavor of the fruit.
3, buy fruit should choose a small or a large? Some of the large head is not added to the expansion agent?
Fruit size is mainly controlled by the variety, not only by size to evaluate whether natural. To fully understand, you can check the relevant website for the main plant variety of a certain fruit, with pictures or text descriptions. For example, if the average weight of a certain fruit variety is 120 grams, then 100 or 140 grams is normal, but 180 grams is rather strange.
Varieties can vary greatly in size, for example, Fuji apples grow large and Gala apples grow small. An expert specializing in bulking agents told me that bulking agents are cytokinin-like substances that make fruits grow bigger and ripen faster, but they affect sweetness and flavor, and are not good for storage. When you buy fruit, one in the same species, choose the medium size of the fruit, do not discriminate against the small growth; second, taste. If the flavor is rich, sweet and sour, there is no need to worry about the expansion agent. Size can be manually adjusted, the taste can not be faked. In the market you can ask to taste; go to the supermarket first buy two less to taste, feel good taste, and then buy more is not too late.
4, fruit is not to eat more seasonal No matter what season, it is better to eat fruit than not to eat. But if possible, give preference to seasonal fruits, because the quality of seasonal is often better than anti-seasonal products. For the north, there is almost no in-season fruit until April. may is for strawberries, and from May to June there are cherries, prunes, apricots, early peaches, loquats, etc. July to August is for watermelons, melons and peaches, with lychees and longans available. september to october is the most abundant, with apples, pears, begonias, sago, pomegranates and kiwis in abundance. Later there are large quantities of oranges, oranges and grapefruit. Some fruits are ripe more than once a year, or different varieties ripen in different seasons, such as mangoes and pineapples.
5, some fruits seem to be particularly bad to keep, very easy to rot, what to do Fruit ripening needs a gas called “ethylene” to start. Some fruits are once the ripening process is started, it is righteous to go all the way to soft rotten. These are fruits that must be bought hard, such as avocados (avocados), domestic kiwis and smoky pears, and bananas. They are rapidly and completely soft once they ripen and have to be eaten within two days and cannot be transported or stored. When buying such fruits, feel them carefully, and the fruit should not be bruised. After buying, first put these hard fruits into a plastic bag without breaks, and then put one or two apples, begonias, pears and other fragrant fruits, together with the mouth tied up, so that the ripe fruit release of natural ripening gas “ethylene” to play a role. After 3 to 5 days, gently press the base of the fruit, if slightly soft, it means you can eat, to eat in order of softness.
6. fruit on the surface of the bad a little, throw the strange pity, can still eat?
There are several cases of “bad” fruit, some are mold, some are soft and rotten, some are bruised and brown, some are a scar or insects. If it is bruised, it does not prevent eating at all. Just remove a small piece of the browned part. Scars and bugs are also not a hindrance to consumption. Soft and rotten fruit can be removed from the soft part, the rest of the part can be eaten if there is no moldy smell, but may have the smell of alcohol fermentation, not delicious but non-toxic. If it is long mold, you should be careful. Because the mold may secrete toxins. If only a small piece, more cut away some can. If the proportion is large, for insurance purposes should be thrown away.
