Many people think that judging whether a fruit is sweet or not is just a matter of knowing it, but in fact some fruits that are not sweet, such as pitaya and kiwi, have a slightly acidic taste, but if they are measured with a sugar meter, they will find The data shows that the sugar content is not low. Therefore, judging the level of sugar in fruits, fruit is not sweet, just rely on the taste is very unreliable, the use of professional testing instrument for sugar testing, can make the fruit sweetness have standards to follow, to protect the fruit market, high-quality fruit supply.
Kiwifruit, watermelon, and grapes are three different kinds of fruit. After these three kinds of fruit, different people have different sensory feelings. For example, some people think that watermelon is sweet and kiwi is too sour. It must be Watermelon has a high sugar content; some people think that grapes and watermelon are sweet, sugar content should be the highest, and kiwifruit acidity and sweetness should be the lowest; others also feel that the sweetest of the grapes are. The kiwifruit has some acid in its sweetness, and the grape should have the highest sugar content. Therefore, if sensory perception is used, then 100 people may have 100 kinds of feelings about the sweetness of the fruit, which makes it impossible to accurately judge the sweetness of the fruit. However, if the sugar meter is used to detect the sugar, the sugar value can use the number. Said, for example, the grape's sugar content is 22.6°, the watermelon's sugar content is 6°, and the kiwifruit's sugar content is 9°. Such a comparison we can clearly know the size of their sugar content are grape> kiwifruit> watermelon.
The application of sugar meter can not only clearly reflect the sugar content of fruits, but also can be used to set sweetness standards for different fruits, so that in the subsequent fruit production and trading process, we only need to use the sugar meter. Determine the current sugar content of the fruit, and then compare it with the sweetness standard of the fruit, you can clearly know the quality of the fruit size, provide a reliable basis for the formulation of fruit prices and quality assurance.
