Which of the 5 ways to wash fruit is the most reliable?

In fact, if you search on Baidu about how to wash fruits, you will find a variety of methods. So, which method is relatively more reliable and reassuring? We selected 6 common methods and conducted a set of simple experiments.

The first method: Soak in water

Time: 1 hour

Serving size: 1 bowl

Put the pears and black currants directly into a bowl of clean water (tap water), soak for an hour, then rinse them again with clean water.

Result: The water quality has basically not changed, and a small amount of impurities can be seen precipitating. The wax on the surface of the pear has been slightly removed, and it doesn't feel as greasy as before. The surface of the blackcurrant has not changed much, and there is still a small amount of fruit powder remaining.

The second type: starch cleaning

Time: half an hour

Dosage: 2 scoops

Add two spoons of starch to a bowl of water, stir well, and add pears and black currants. Soaking time is about half an hour. Rinse again with clean water.

Result: The water quality did not change much (because of the addition of starch, the water quality itself was relatively turbid), and there were a small amount of impurities on the water surface. The wax on the surface of the fragrant pear has been basically washed off, and the glossiness of the pear surface can be seen, and it feels very clean to the touch. There is still some white substance left on the surface of the blackcurrant.

The third method: rub with salt

Time: About 5 minutes

Dosage: 4-5 scoops

Sprinkle salt directly on the surface of the pear, then rub it repeatedly with your hands and rinse it with clean water.

Results: This method involves rubbing salt particles repeatedly on the fruit skin to remove the wax. The effect is quite good. The wax layer on the surface of the pear is basically removed, and it doesn’t feel greasy when touched by hand. However, just to wash one pear, I used about four or five spoons of salt, which felt a bit "too wasteful".

The fourth type: rice water bubbles

Time: half an hour

Serving size: 2 bowls

Take 2 bowls of rice water after soaking rice for about 10 minutes, directly put the pears and black currants in, soak for about 30 minutes, take out and rinse with clean water.

Result: The rice water that I had high hopes for turned out to be basically useless against wax. There are indeed impurities precipitated on the water surface, but when you touch it, the wax on the surface of the pear and black currant is still there, and it feels almost the same as if they had not been washed.

Fifth: detergent

Time: 20 minutes

Dosage: 3 drops

The detergent used in this review is a certain brand of green tea, which is said to be natural and pollution-free and can be used to wash fruits and vegetables with confidence. According to the dosage ratio specified in the instructions, add 3 drops of detergent to clean water, add the pears and black currants, soak for about 20 minutes, and then rinse twice with clean water.

Result: There was basically no change in water quality and no impurities floated up. After rinsing with clean water, I feel that the wax and white fruit powder are basically cleaned away, and it doesn’t feel greasy to the touch.
