Glucose, fructose, sucrose, lactose, and maltose are important components in candies, which have a significant impact on the taste, sweetness, texture, and other characteristics of candies. By measuring the content of these components, the quality and taste characteristics of candies can be understood, thereby determining the quality and grade of candies.

Secondly, the metabolism and absorption of glucose and fructose have a significant impact on human health. For patients with diabetes and people who need to control their blood sugar, it is very important to know the glucose and fructose content in candy, which can help them better control their blood sugar level and choose suitable food.

In addition, measuring glucose, fructose, and other substances in candies can also help candy production enterprises control product quality and optimize formulas. By understanding the content and proportion of different ingredients, enterprises can adjust their formulas and production processes, improve the stability and taste of products, and thus meet the needs and expectations of consumers.

In summary, measuring glucose, fructose, and other substances in candies is an important testing task for candy quality, human health, and enterprise production.
