Is the fruit peel edible?
According to experts' analysis, fruit peel is a health product, not a pesticide.
When eating fruit, compared with the popularity of pulp, the situation of peel is different-some people have become loyal fans of peel because of Pete's delicious and nutrition, and some people think that peel contains a lot of pesticides, so they abandoned it. So, is the peel edible?
Zheng Fang: Because of nutrition, the peel is not only rich in vitamin C, pectin and cellulose, but also contains antioxidant polyphenols such as anthocyanins, which is of great benefit to the human body.
Corresponding: Because of pesticides, discarded peels are more likely to come into contact with pesticides in the growth process than pulp, which will cause pesticide residues and be harmful to human body.
Expert opinion: Don't worry too much about pesticide residues in peel.
At present, all kinds of herbicides and fungicides are always sprinkled on the soil of farmland, and they will enter the fruit trees from the roots. In order to reduce pests such as fruit eaters, pesticides are injected from bark and flow through trees along pipes and sieve tubes in the trunk. Professor Fan Zhihong from China Agricultural University said: Most pesticides will not be exposed from the peel at all. Now, most orchards must be bagged after fruiting, which reduces the chance of direct contact with any sprayed pesticides.
Worried about the pesticide residue in the peel, let's understand the nutritional value of the peel: Take the apple as an example, its peel is rich in vitamin C, pectin and cellulose, and the polyphenols in the peel are much higher than those in the pulp.
A study shows that the total polyphenol content in apple peel is 307 mg/100 g, the total flavone content is 184 mg/100 g, and the proanthocyanidins content is 105 mg/100 g, which is rich in nutrients that pulp can't match. It is found that polyphenols extracted from apples have significant anti-radiation effect, which can delay the survival of irradiated animals, promote the discharge of lead pollution in animals, and significantly reduce the lead content in liver, bones and blood of lead poisoning mice.
