Fruity beverages discolor with paper towels when stirred, expert: pigments increase liver burden

Fruity bottled drinks with sweet and sour taste and good taste are loved by people, especially some children even drink drinks as water. Mr. Wang, a citizen, conducted a small experiment at home to warn children that a lot of Pigments and sugar. The experiment process of Mr. Wang is very simple. Put the paper towel into the orange drink and stir. After one or two minutes, the orange drink becomes transparent Spirit and the paper towel becomes orange. He also weighed out more than one or two sugars with an electronic scale and said that the sugars were comparable to the sugar contained in a bottle of beverage.

Is the color and sugar content in drinks really high? Yesterday, the reporter came to Shark Park Children s University Laboratory, a private institution, and asked professionals to test it and see what the truth is.

The experimental process that Mr. Wang Wang showed to the children at home was very simple. Pour a brand of orange soda drink into a glass, put it in a paper towel, and quickly stir with a chopstick. After 30 seconds, the color of the drink in the cup gradually became lighter, and the color on the paper towel became darker. Nearly 1 minute, the beverage in the cup gradually turned white, and the paper towel became orange.

After that, he took out a small bowl and poured nearly half a bowl of white granulated sugar into it. He said to the five-year-old child, This is the total sugar content in a bottle converted from the data in the beverage formula table. Drinking beverages is actually drinking sugar. Mr. Wang cautioned children to drink fewer beverages in the future.

Although I usually feel a bit sweet after drinking a beverage, and my tongue will be stained when I drink a colored beverage, I did not expect that the content of pigment and sugar in the beverage is so high. Ms. Feng, a citizen, expressed some doubts. To this end, yesterday, with the help of professionals, an experiment was conducted on the content of pigments and sugars in beverages.

The experimenters bought a bottle of orange soda drink, a bottle of fruit juice drink, and a bottle of milk-containing drink on the market, and prepared relevant reagents and electronic scales for comparison experiments one by one.

The experimenter took out two beakers of the same size, one with water and one with an orange drink. Two drops of brown pigment were added to the water cup, and then ordinary paper towels were placed in the two cups, and they were continuously stirred with a stirring rod. After 30 seconds, the liquid color in both cups became slightly lighter, and the color of the paper towel gradually changed to brown and orange. After continuously stirring for 1 minute and 30 seconds, the brown pigment water became light brown , the orange drink became light orange, and the paper towels changed from white to brown and orange. Experimenters said that comparing a cup of tea-colored pigmented water to a colored beverage is to prove that paper towels have adsorption on pigments, and that non -paper towels will react chemically to cause color adhesion after encountering the beverage.

After the experiment, the reporter observed that the contrast between the beverage in the cup and the bottle did lighten. After repeating the experiment five times, the color of the beverage in the cup became lighter and lighter, but it did not become transparent. Sprite

Imported, the experimenter weighed the white sugar with an electronic scale and converted the sugar content in the ingredient list of the beverage bottle. The experimental results show that the sugar content of a 600ml bottle of a soda drink is equivalent to 66g, the sugar content of a bottle of 500ml milk-containing beverage is 30g, and the sugar content of a bottle of 450ml fruit juice drink is 42g.

勇 Wang Yongjian, vice president of Xi an Nutrition Association, said that food coloring is basically divided into two types, one is natural coloring and the other is artificial coloring, and the coloring added to beverages is mostly artificial coloring. The above experiments can only prove that the beverage does contain pigment, but cannot judge the content of pigment and other aspects. The pigments added to general foods are in compliance with national standards. The use of such pigments within the defined categories will not have much impact on the human body, but the pigments do not have any nutritional value. The human body will increase the metabolism of the liver after ingestion. burden.

Wang Yongjian said that even beverages that claim to be healthy drinks belong to the category of high sugar, and the sugars contained in them are monosaccharides, which can only provide the body with blank calories. At the same time, metabolism of these sugars will also consume B vitamins in the human body. Drinking can cause loss of appetite, anorexia and picky eating, induce dental caries, cause obesity, and increase the risk of diabetes. He suggested that drinking beverages at dinner parties would not cause too much harm to the human body, but it is harmful and unhelpful to use water instead of water to form a habit, especially for children, who are in the stage of growth and development., Excessive intake of beverages may also cause sugary mental irritability and affect children s health.
