What s wrong with the white sap on pineapple seedlings?

According to the scientific explanation I read in the book, these things are okay, it should be the juice oozing out of the pineapple after cutting, it should not be eaten, and the juice oozing out means that your pineapple is very fresh. But eating some of it won't affect the body. Tree pineapple is a hot and humid thing, and it is not good to eat too much.

The flesh of pineapples is white because of the problem of pineapple varieties, there is a kind of pineapple called milk pineapple, and its flesh is white like milk. The skin of the milk pineapple is green, as if it is not ripe, and the taste is sweet and sour.

Note that the pineapple should be soaked in salt water before eating, and some of the organic acids contained in it can be decomposed in the salt water, removing the sour taste and making the pineapple taste sweeter. You can also put it in boiling water and boil it before eating it. Bromelain begins to denature at 45 50, and by 100 more than 90% is destroyed; Glycosides can also be destroyed and eliminated at the same time; Serotonin is soluble in water.

After boiling, the taste has to be improved. Don't eat too much pineapple every time, excessive consumption is harmful to the stomach.

The reason for this is bromelain. If the pineapple has been left for more than 3 days, it is best not to eat it, pineapple, like sugarcane, will react with the air after a long time.

Bromelain is a pure natural plant protease extracted from the stems, leaves and skin of pineapple fruit, which is refined, purified, concentrated, enzyme immobilized and freeze-dried. Its appearance is a light gray powdery stool with a volume of 33,000 and an isoelectric point.

The best quality bromelain is obtained by using the middle stem of pineapple, filtered and concentrated by ultrafiltration method, and low freeze drying. It has been widely used in food, and other industries. Edible enough. Bromelain is used as a food additive.

The pineapple has a white flower-like part inside it, which is actually the flower column of the pineapple.

The edible part of the pineapple is mainly composed of the inflorescence axis of the fleshy enlargement, the flowers arranged in the periphery in a spiral shape, the flowers are usually not fruitful, and the remaining flowers are surrounded by lobes into a cavity, and the cavity contains shrunken stamens and flower columns, so it will show white clusters in the flesh of the pineappleIn this case, the pineapple does not affect the consumption.

Growth habits

It has strong resistance to negativity, likes diffuse light, and avoids direct light, but sufficient light is still needed for high yield and high quality. Pineapple has a wide range of suitability to soil, but should not be neutral or alkaline soil, cohesive or unstructured silty soil, pH 5-6.

It is more suitable for pineapple growth in places with annual rainfall of more than 1000-1500 mm and uniform precipitation time distribution (monthly rainfall of 100 mm). The groundwater table of 30-50 cm is conducive to the growth of roots.

The inside of pineapple is whitish and unsuitable for consumption, which produces harmful substances and causes bloating and diarrhea after eating.

The "black heart" and "white heart" of pineapple are actually the "rotten heart disease" on crops. This disease is mainly related to the management of fruit planting by fruit farmers, and the climate of Hainan is also high temperature and rainy, if the rain is too much and the fertilizer is not reasonable during the growing season, it is easy to cause lesions. The disease is generally not visible during the harvest period, and may only be evident after the pineapple has been cut down and transported and stored.

Pineapple fruits are of good quality and nutritious, containing a lot of fructose, glucose, vitamins B, C, phosphorus, citric acid and protease. Each 100 grams of pineapple contains grams of water, protein, fat, fiber, niacin mg, potassium 126 mg, sodium mg, zinc mg, carbohydrate grams, calcium 20 mg, phosphorus 6 mg, iron mg, carotene mg, thiamine mg, riboflavin mg, vitamin C8 30 mg, ash grams, and a variety of organic acids and pineapple enzymes.
