yesterday ate with relish and a Gala apple, in the enjoyment of better taste, it is also a sigh of delicious fruit. I do not know why, those who are not peel the apple, eating up the total do not think there is Taste. People love the beauty of appearance, have a strong scent, it seems that in a great extent related to skin contact. Just think, if directly see a strip of white flesh apple coat, who would be interested to buy and taste it?
However, eating fruit is not an easy task. Skin even though it no doubt rich in vitamin C, rich in pectin, cellulose-rich, rich in antioxidant anthocyanins and other polyphenols, but all this should not become a reason to enjoy the absolute peel, Since there is a lot of people are worried about pesticide inside.
Today, the pesticide is already all-pervasive. Federation of farmland soil sprinkled a variety of herbicides and fungicides, they will enter the fruit from the root of them. Like in order to reduce the borer pests, but also from the bark filled with pesticides, the catheter along the trunk stream and sieve through the tree. In other words, even if the peeling, and pesticides also can not be avoided.
often think of these things, I am of the pesticide on the skin no longer care about, because most pesticides are not from the pericarp come into contact with, and now the majority of orchards in the setting have to be bagged after treatment, reduced pesticide spraying and any chance of direct contact.
Happiness to enjoy at my skin after a period of time, others reported that made me slightly confused. One study found that from the road near the apple comparison, the lead content will be significantly increased, while the peel of lead which is obviously higher than the flesh. Another study found that lead, cadmium, copper, tin, thallium and other heavy metal elements in the pericarp of which are significantly higher than the concentration of pulp. For example, the lead content of the flesh are 0.53mg/kg, the pericarp is 0.76mg/kg, about half high. For cadmium and thallium element element, the pericarp pulp concentrations are about 4 times that are 3 times more copper, tin are 12 times.
see here, I almost want to give up considering peel. However, Read on, determined to shake occurred. Because data indicate that the human body useful, easy meals in the absence of Zinc, as well as beneficial for the prevention of diabetes chromium, the concentration of fruit pulp were 4-fold. Meanwhile, the study also found that because of lead in the exhaust are direct contact with skin and be absorbed, if put on bags of lead content in fruit peel can be decrease by as much as 80 percent. It seems that the risk of skin does not seem very terrible.
At the same time, peel the polyphenol content is much higher than the internal flesh. Determination of a study proved that苹果皮of total polyphenol content of 307mg/100g, total flavonoids for 184mg/100g, Proanthocyanidins for 105mg/100g, these data are to catch up by the flesh. The study found that apple extract polyphenols very significant anti-radiation effects, radiation can be delayed by an animal's survival period; it have to promote the animals from the role of lead pollution, significantly reduce lead poisoning in mouse liver, skeletal and blood lead content.
can be seen that although苹果皮contain slightly more than the flesh of the lead, but also help rule out the possibility of a strong ability to lead poisoning. Both compared to benefit victims of balance, and not so terrible.
After all, we eat apple benefits, to a large extent comes from its nutrient composition and health. Do away with these things every day to drink pure water, what significance does it have.
my personal recommendations for eating苹果皮is this: If you enjoy eating, it continues to stop. If you do not like to eat, thin and peeling do not have self-reproach.
Peel's advice to eat one: may wish to give priority treatment selection bagging apples. This apple skin clean and uniform, to be contaminated gases, such as the impact of spraying pesticides is relatively small.
advice to eat fruit peel 2: Fall ripe apple, fresh apple sales at that time without Preservative treatment, eating peel safer. The least rest assured that foreign远渡重洋from apple, because they must be fresh to go through treatment, and waxing fruits abroad become more popular.
advice to eat fruit peel 3: fresh apple surface has a layer of natural wax fruit, but have thin fruit powder, not light people learn a lesson from it. After the apple harvest, in order to enhance the value of merchandise and slow water loss of apple, often waxing polishing machine, and may have antistaling agent deal with questions like, they see the beautiful shiny surface of apple in particular, especially the off-season apple, best to eat after peeling.
advice to eat fruit 4: Choose the best there is pollution-free, green and organic certified apples, apple such heavy metals and pesticide residues will be much smaller, even if not equal to zero, will苹果皮than ordinary residual small amount of fruit to eat feel more at ease.
