Is the pear a bit sour? Is it bad? Is the pear a bit sour? Can I still eat it?

In most of our minds, pears are very sweet. Many people like to eat pears. Some people find that the pears they buy become sour after a period of time. Few people know the reason. Therefore, we need to understand whether pears that are a little sour are bad. Can pears that are a little sour still be eaten?

First, let's talk about the first situation. The pears have been eaten and stored at room temperature. After tasting them again, you find that the pears are a bit sour. In this case, don't continue to eat them. Just throw the pears away. As long as the pears have been eaten or cut, if they are kept at room temperature for more than 6 hours, they may deteriorate or rot. Generally, the sour smell we smell is the beginning of deterioration. Another situation is that the pears we bought back have no signs of being eaten, and there is no sign of deterioration or rot. In this case, the pears are generally not very mature, so they taste a little more sour. If you can tolerate the acidity, you can continue to eat it, but if you don't like sour food, you can leave it for a while before eating it.

Pears are too sour to eat, but the nutritional value of pears is relatively high. If we eat more, it will be good for our health. In addition, the price of pears is relatively affordable. We can buy them on some e-commerce platforms. The price of 1 catty is about 12 yuan. Many people like to eat this delicious fruit. If the pears are left for too long, the lysosomes in the cells will automatically rupture and release a large amount of enzymes. This will cause the chemical reactions in the cells to proceed violently. Most of them undergo anaerobic respiration, releasing a large amount of lactic acid and organic acids, so the pears taste sour.

When the black heart of a pear is shallow, it is generally difficult to distinguish. If the black heart of a pear is greater, the color of its skin will darken. However, the flesh that has not turned black is still edible. Most pears become black-hearted and rotten because cracks appear under the pear, causing the pear core to be infected by bacteria and other microorganisms. However, since there is also a protective layer between the pear core and the flesh, the flesh is generally good after this happens, so such pears can be eaten. However, if the pear has a black heart and is left for a period of time, the flesh may also be infected, causing it to deteriorate. Such pears cannot be eaten. Therefore, for pears with a black heart, it is best to see if the flesh has deteriorated or has an odor. If it is good, it can be eaten.

If the pear skin has black spots, and the black spots are sunken after being pressed, it means that the pear has begun to mold and has produced a large number of microorganisms. Even if the black spots are dug out, the rest of the flesh may be infected, so this kind of pear should not be eaten. In addition, pears will also undergo oxidation and turn black after being hit or scratched. If only the skin turns black and the flesh inside is not rotten, it can continue to be eaten.
