With the progress of the times and the improvement of the convenience of life, people know more and more how to treat themselves by enjoying delicious food, but at the same time, life is full of processed food. Recently, it has even been reported that children's addiction to dessert drinks will become one of the culprits of growing taller! We need to know more secrets about the health effects of sweet drinks …
You don't know the sugar crisis
Whenever you are in a bad mood and feel tired, do you also like to have a bite of dessert to sweep away your gloomy mood? At an early age, the baby at home has become a "sweet ant" who loves sweets? Although many people agree that delicious and exquisite candy brings us full happiness, do you know the true face of these common sweets? I'll take you to see him now!
Candy and drinks, unexpected health crisis
Whether we get information from newspapers and magazines or go to the grocery store or supermarket to buy it in person, we must be familiar with the following sugars in our daily life:
Sucrose-molecular structure: disaccharide (glucose+fructose). Natural food source: extracted from sweet sugarcane, beet and other vegetables and fruits. Remarks: The main components of white sugar, brown sugar and brown sugar are sucrose, but their nutritional values are different according to the fineness of processing.
Fructose-molecular structure: monosaccharide. Natural food sources: fruit, honey, etc.
Glucose-molecular structure: monosaccharide. Natural food sources: fruits, vegetables, etc. Remarks: Glucose is the main energy source of cells.
Honey-molecular structure: disaccharide. Natural food source: after bees collect nectar, they turn it into honey sacs and cook it in the hive. Remarks: Besides glucose and fructose, it also contains many vitamins, minerals and amino acids.
Maltose-molecular structure: disaccharide (glucose+glucose). Natural food source: It belongs to the fermented products of grain and malt, or the hydrolyzed products of starch, and is often added to processed food.
Is fructose made of fruit?
The traditional fructose is indeed extracted from fruit, but nowadays, in order to reduce the cost, most merchants choose "fructose syrup" to flavor it.
High fructose corn syrup is made from starch, hydrolyzed into dextrin and maltose, and then decomposed into glucose by catalysis. Finally, glucose isomerase is used to convert glucose into syrup with higher sweetness. Compared with fructose made from natural fruits and vegetables, although it is sweeter, it lacks natural vitamins and minerals.
The nutritionist then explained: "Fructose syrup is mainly made of corn, which has the characteristics of high sweetness, high yield and low cost, and liquid fructose is easily mixed with food and beverage, so it is often listed as the first choice in the catering industry. In addition, high fructose corn syrup has the following characteristics:
(1) Traditional fructose has low supply and high cost, while fructose syrup has high output and low cost.
(2) The sweetness of high fructose corn syrup is 1.7 times that of sucrose, and the same sweetness can be achieved with a small dose.
(3) Liquid fructose is easier to dissolve and mix than sucrose.
(4) Fructose has excellent stability and is not converted by acid in acidic beverages, so the quality of beverages is stable.
