Why do we need to sprinkle salt on watermelons? What are the effects and functions of sprinkling salt on watermelons?

Watermelon is a favorite fruit in summer. It has a lot of juice, sweet taste, and high nutritional value. It can clear away heat and relieve summer heat, and can also replenish a lot of water for the human body. But recently, some people like to sprinkle salt on watermelon when eating it. Why is that? What are the effects and functions of sprinkling salt on watermelon?

Why do we sprinkle salt on watermelons?

1. Many people sprinkle some salt when eating watermelon, imitating the way Japanese people eat watermelon. Because Japanese people have extremely high requirements for taste when eating food, they often sprinkle some salt when eating watermelon, which can make the taste of watermelon more tempting.

2. Sprinkling salt when eating watermelon can enhance the taste of watermelon. From a scientific point of view, adding salt when people eat watermelon can enhance its sweetness, because salt is also called a taste enhancer. The trace ingredients it contains will react significantly with the sweeteners in the watermelon, which will increase the activity of the sweeteners and make people feel that the watermelon has become sweeter when they eat it again.

The efficacy and function of sprinkling salt on watermelon

1. The main purpose of sprinkling salt on watermelon is to increase the sweetness of the watermelon. Because salt is called a taste enhancer, it will significantly enhance the sweetness of the watermelon after it comes into contact with the watermelon. It can make the watermelon that is not very sweet taste better and feel particularly sweet when eaten.

2. In summer, people like to put watermelon in the refrigerator and take it out after a few hours before eating. At this time, the cut watermelon will also breed some bacteria in the refrigerator. Salt has a certain bactericidal effect. Sprinkling it on the surface of the watermelon can play a certain sterilization role. It can prevent these bacteria from entering the human body through inhalation and reduce their harm to the human body.

3. Improving the body's absorption and utilization rate of water is also the main effect of sprinkling salt on watermelon. Because in the hot summer weather, the human body consumes energy faster and loses water seriously. At this time, only eating watermelon and replenishing the right amount of water can quickly disappear. If you sprinkle some edible salt on the surface of the watermelon, it can increase the body's absorption rate of water, allowing the water to stay in the human body for a longer period of time, making the watermelon's hydrating effect more outstanding.
