Fruit is an indispensable food in people's daily diet and is deeply loved by people, especially young women and pregnant mothers. Because they are convinced that fruit can not only make beauty beauty, but also make the baby born smarter and more beautiful. So, is fruit really so magical? In recent years, the taste of fruits is getting sweeter and sweeter. Is it because merchants have injected sugar water?

The taste of fruits is often sweet and sour, and the higher the maturity, the higher the sweetness. The sweetness of fruit mainly comes from the carbohydrate it contains, which is what we often call sugar. When it comes to sugar in fruit, many people think that fruit is sweet because it contains fructose. In fact, the sugar in fruit is not only fructose, but also contains fructose, sucrose, glucose and other sugars, but the content of fructose is the highest.

In recent years, the taste of many fruits is getting sweeter and sweeter, and many people begin to question whether the merchants have injected sugar water into the fruits. In addition, there are also pictures or videos about fruits sweetened with sugar water that have spread wildly on the Internet, especially popular fruits such as watermelons, which have been repeatedly recruited. Is this really the case?

Why is fruit so sweet?

The sweetness of fruit mainly comes from the sugar in the fruit, and the degree of sweetness is related to many factors, such as the maturity of the fruit, the lighting environment where the fruit is planted, the adequacy of water, etc. These factors may affect the sweetness of the fruit. Many times, the fruit we bought is not very sweet, but after a few days, we will find that the sweetness increases, which is the change of sweetness caused by the increase of fruit maturity.

Because fully ripe fruits taste sweeter, they are more prone to rot during transportation. Therefore, in order to pursue higher economic benefits, merchants often start picking fruits when they are 78% or even 56% ripe, and then transport them to various places for sale. Therefore, most of the fruits we buy are not fully ripe fruits, and their sweetness is not so sweet. So, in order to increase the sweetness of fruit, is it feasible to give fruit an injection?

In fact, the requirements for the surrounding environment during storage and transportation of fruits are very strict. Because fruits are rich in water and sugar, they are particularly prone to bacteria, so even if they accidentally cause mechanical losses to fruits, fruits will rot quickly.

Take the example of "Injected Watermelon" which was once wildly circulated on the Internet and was accused by netizens of being injected with sodium cyclamate and carmine ".Although some people swear that delicious watermelons can be" fed "through these, in actual operation, it will be found that not only the needle tube is particularly easy to block, but also sugar water will flow out from the eye of the needle after the watermelon is injected.

Therefore, this operation is not only difficult, time-consuming and laborious, but also will speed up the decay and deterioration of fruit by adding sugar water to the fruit, thus damaging the economic interests of fruit farmers or fruit merchants. In that case, who else would go to so much trouble to do something at the expense of others?

Why are fruits getting sweeter and sweeter?

The main reason why the sweetness of fruits is getting higher and higher today is actually the cultivation of fruits by fruit farmers. Because the varieties with higher fruit sweetness are loved by consumers, and the fruit sales of these varieties are very considerable, the economic benefits brought to fruit farmers are also relatively high. Therefore, in the process of fruit tree cultivation from generation to generation, in the consumer's taste and the conscious selection of breeding by fruit farmers, there are more and more fruits with high sweetness. With the progress of science and technology, fruit farmers have also introduced different kinds of fruits from abroad, which are also fruit varieties with good taste, so many fruits we eat now are getting better and better in taste and sweetness.

Although sugar water is rarely injected into fruits, some fruits are indeed sweetened by unscrupulous merchants, such as saccharin jujube. When people buy jujube, many people think that green jujube has low maturity and bad taste, so some merchants soak jujube with saccharin sodium to cater to these consumers' psychology, thus making jujube red and sweet.

in view of this situation, it is suggested that consumers should go to a regular fruit supermarket to buy dates, and try to choose dates with natural surface color when picking dates.
