Do you want to eat apples to peel? Four strokes to thoroughly clean the apple
As the saying goes, "An apple a day, the doctor stays away from me." Since the phrase appeared, Apple has become a lot of people's daily fruits. Indeed, according to statistics, Apple is the best-selling fruit. However, fruits with such rich nutrition cannot survive the invasion of pesticide residues. How can we clean the apples?
Eat apple peeled or not peeled?
Many people think that apple has many pesticide residues, so it should be peeled when eating. However, apple peel contains many biologically active substances, such as phenols, flavonoids, and octacosanol. These active substances can inhibit the angiotensin-converting enzyme that causes high blood pressure and help prevent chronic diseases. , Such as cardiovascular disease, coronary heart disease, reduce its incidence.
Foreign studies have also shown that apple peel has stronger antioxidant properties than pulp, and apple skin has higher antioxidant activity than other fruits and vegetables. The antioxidant capacity of the skin of an ordinary size apple corresponds to the antioxidant capacity of 800 mg of vitamin C. Octacosanol in apple peel also has anti-fatigue and body-building effects.
What are the nutrients in apple peel?
Vitamins: Researchers at the University of Illinois said that apple peels are rich in vitamin A and vitamin C. Vitamin A, also known as retinol, helps maintain normal visual function and bone growth. Vitamin C promotes wound healing and enhances immunity.
Minerals: Researchers at the University of Illinois believe that apple husks are rich in minerals, including calcium, potassium, phosphorus, iron and folic acid. Eating apple husks is also beneficial to the body's effective absorption of minerals.
Among them, calcium and phosphorus make the teeth and bones stronger, potassium can enhance the heart and digestive function, iron is an important guarantee to meet the needs of normal red blood cells to prevent anemia and maintain good health.
Dietary fiber: About two-thirds of the dietary fiber in apples is found in the skin. Adequate dietary fiber intake reduces the risk of heart disease and can also prevent constipation.
From this it can be seen that apple skin is still not good.
If you do not go to the apple skin, how can you wash the pesticide residue thoroughly?
Method One: Wash
After the apple has soaked in water, put a little salt on the skin, and then hold the apples with both hands and gently squat, the dirt on the surface will soon be clean, and then washed with water, you can rest assured to eat.

Method two: starch washing
Prepare a small bowl, put some starch, and then wash the apples. This method is also suitable for pears and grapes, etc., and the surface of the fruit is not easily discolored.

Applying toothpaste to the surface of apples is a good way to clean them. It is also a good idea to wash the apples with hot water, so it is easy to wash away the apple preservatives.
Method 4: Fruit lotion
It's best to buy special lotions for washing fruits in supermarkets. Experts caution against using detergents that are difficult to guarantee because of the poor quality of detergents. Not only are they not clean, they may also have chemicals that are harmful to health.
