A handheld sugar meter can measure the sweetness of fruits
The handheld sugar meter adopts a prism made of high-performance and durable optical glass, which has good durability and is not easy to scratch; Humanistic engineering design, one hand measurement can be achieved by pressing the button, and clear water can be reset to zero; The innovatively designed metal sample tank can quickly maintain the temperature of the sample consistent with the prism, making sampling simple and not easy to leak and contaminate the instrument; LCD large screen digital display, automatic temperature compensation, battery operated, lightweight and easy to carry; Easy to maintain, meets IP65 standards, and can be directly rinsed with running water.
The design principle of a handheld sugar meter:
When light enters another medium from one medium, it undergoes refraction, and the ratio of the incident angle sine is constant, which is called the refractive index. The content of soluble solids in fruit and vegetable juice is directly proportional to the refractive index under certain conditions (at the same temperature and pressure). Therefore, measuring the refractive index of fruit and vegetable juice can determine the concentration (sugar content) of the juice. The commonly used instrument is a handheld refractometer, also known as a sugar mirror or handheld sugar meter. By measuring the soluble solid content (sugar content) of fruits and vegetables, the quality of fruits and vegetables can be understood, and the maturity of fruits can be estimated approximately. A handheld sugar meter is usually cylindrical in shape. Place the sugar solution to be measured into an open slot at the back, spread it evenly, close the lid, and then point the sugar meter towards the light. Looking through the hole in the front, you can read it.
When it comes to "sugar", many people judge it by its taste. If it gives people a sweet taste, it means it contains sugar, and if it doesn't have a sweet taste, it means it doesn't contain sugar. Actually, this is not reliable. "Sugar" not only refers to glucose and fructose that we can taste sweetness, but also includes starch and carbohydrates that we cannot taste sweetness. Therefore, it is not possible to determine whether a food contains sugar based on its taste. There are four main types of sugars in fruits: glucose, fructose, sucrose, and starch. Among them, fructose is sweet - equivalent to 1.7 times the sweetness of sucrose, followed by sucrose, followed by glucose - equivalent to 0.7 times the sweetness of sucrose, and starch - has no sweetness. Most fruits have a sweet taste, so I think they have a higher sugar content. Many friends who want to lose weight start to get conflicted. They want to eat sweet and delicious fruits, but they are afraid that too sweet fruits have too high sugar content, which will lead to weight gain and is not conducive to health. Friends who want to lose weight and eat fresh fruits can use a handheld sugar meter to choose their favorite fruits. The sweeter the fruit, the higher the sugar content. Don't be fooled by taste anymore!
