Apple peel

Apple peels are rich in antioxidants and bioactive substances, and eating apple peels is good for your health. Apple peels contain many bioactive substances, such as phenolic substances, flavonoids, and octacosanol, which can inhibit angiotensin-converting enzymes that cause high blood pressure, and help prevent chronic diseases such as cardiovascular disease and coronary heart disease, and reduce their incidence.

Consuming apple peel can reduce the incidence of lung cancer. Foreign studies have shown that apple peel has stronger antioxidant properties than the pulp. The antioxidant effect of apple peel is higher than that of other fruits and vegetables. The antioxidant capacity of the peel of an ordinary-sized apple is equivalent to that of 800 mg of vitamin C.

Octacosanol in apple peel also has the effect of resisting fatigue and enhancing physical strength. Apple peel can inhibit the enzyme activity of dental plaque and the growth of bacteria in the mouth, has an anti-corrosion effect, can protect teeth. It can also make the skin white and tender, prevent the formation of melanin, and has a cosmetic effect.

Functional foods are developed by extracting bioactive substances from apple peels. Apple peel powder, as a valuable food additive, can be used to produce fortified foods. Adding a small amount of apple peel powder can increase the content of polyphenols and flavonoids in foods.

The efficacy and function of apple peel

1. Apple peel contains the most dietary fiber. The skin of a medium-sized apple contains 4.4 grams of dietary fiber. After peeling, the dietary fiber in the apple flesh is only 2.1 grams.

2. Apple peel contains the most vitamins. The peel of a medium-sized apple contains 8.4 mg of vitamin C and 98 IU of vitamin A. After peeling, the apple flesh contains only 6.4 mg and 61 IU of these two vitamins.

3. Eat apples with the skin to protect your lungs. A study published in the U.S. magazine Health found that apple peels are rich in the natural antioxidant quercetin, which can protect the lungs from pollutants. Eating at least five apples with the skin on a week can improve lung function.

4. Eat apples with the skin to protect memory. An early study also found that the antioxidant quercetin rich in apple peels helps prevent brain tissue damage associated with degenerative diseases such as Alzheimer's disease, thereby helping to protect memory.

5. Apple peel has anti-cancer effects. A study conducted by Professor Liu Ruihai, a food science expert at Cornell University, and his colleagues published in the American Journal of Agricultural and Food Chemistry found that apple peel has good anti-cancer and cancer prevention effects. The researchers identified more than a dozen triterpenoid compounds from apple peel, all of which can inhibit the growth of cancer cells such as liver cancer, colon cancer or breast cancer, and can also kill cancer cells.

6. Eating an apple with skin every day can help you lose weight. Apples are high-fiber, low-calorie foods. Eating them regularly will not make you feel hungry and reduce calorie intake, which can help you lose weight.

At present, many manufacturers have developed functional foods by extracting bioactive substances from apple peel. Apple peel powder, as a very valuable food additive, can be used to produce fortified foods. Adding a small amount of apple peel powder can increase the content of polyphenols and flavonoids in food.
