Rock sugar is formed by recrystallization of white sugar under certain conditions. Their chemical composition is sucrose.
If brown sugar is stored for a long time, molasses will be oxidized, making the color darker and sour, so brown sugar can no longer be eaten.
Generally speaking, white sugar is flat and has high purity; Brown sugar is warm and contains many impurities; Rock candy is the crystallization of sugar.
Efficacy: Proper consumption of white sugar helps to improve the body's absorption of calcium; But too much will hinder the absorption of calcium. Rock candy can nourish yin and promote fluid production, moisten lung and relieve cough, and has a good auxiliary therapeutic effect on lung dry cough, dry cough without phlegm and expectoration with blood.
Although there are many impurities in brown sugar, its nutrients are well preserved. It has the effects of invigorating qi, invigorating middle warmer, invigorating spleen, promoting digestion, enriching blood and removing blood stasis, and also has the functions of dispelling cold and relieving pain.
Therefore, it is often effective for women to drink some brown sugar water because of cold and physical weakness or dysmenorrhea caused after delivery. Brown sugar has an excellent nourishing effect on the elderly, especially those who have recovered from a serious illness.
In addition, brown sugar can also prevent vascular sclerosis to a certain extent, and it is not easy to induce dental diseases such as dental caries.
In addition, when eating edible sugar, you should pay attention to:
1/ Do not use for diabetics.
2/ Dosage: no more than 30 grams per day.
Tips: Rinse your mouth or brush your teeth in time after eating sugar to prevent dental caries. Sugar is easy to produce mites. Don't eat raw sugar that has been stored for a long time, and eat it after boiling. Don't eat too much. People with diabetes should not eat sugar. Pregnant women and children should not eat a lot of white sugar. Maternal women are suitable for eating brown sugar, but don't eat it for too long. Generally, half a month is better. Old people with yin deficiency and internal heat should not eat more brown sugar.
Extended data
The difference between brown sugar and white sugar: white sugar is made by adding carbon to remove pigment on the basis of brown sugar, but isn't it that the more carbon is put, the whiter the polysaccharide is? That's not true. Proper amount of carbon should be put in order to fully absorb the pigment of brown sugar. If it is too much, it is a waste.
The difference between brown sugar and white sugar is mainly the different preparation methods and different nutritional components. Most of brown sugar is produced by indigenous methods, while most of white sugar is made by mechanism.
In terms of quality and nutrition, brown sugar is brown with many impurities and low sweetness; White sugar is white, clean and high in sweetness. Brown sugar is better than white sugar in medicine. Brown sugar contains more glucose (20~30 times more than white sugar), which can be directly absorbed by the human body.
Brown sugar is also rich in iron (twice as much as white sugar), which is necessary for hematopoietic process. Brown sugar contains carotene, riboflavin, nicotinic acid and so on. This is not available in white sugar. These are all nutrients that women need very much.
Brown sugar and white sugar are both extracted from sugar cane or sugar beet. The production process of brown sugar is slightly simpler than that of white sugar, which contains more glucose and cellulose, and releases energy faster and has higher absorption and utilization rate. However, brown sugar contains almost the same sugar and calories as white sugar. Moreover, the taste of brown sugar is not as sweet as white sugar, so people will naturally put more when drinking tea and coffee, so in fact, brown sugar is sometimes more dangerous than white sugar.
It is generally believed that eating white sugar is better than eating brown sugar. But from a nutritional point of view, the nutrition of white sugar is far less than that of brown sugar.
The calcium content of brown sugar is 10 times that of white sugar, the glucose content is 22 times that of white sugar, and the iron content is 3 or 6 times that of white sugar. Brown sugar also contains riboflavin, carotene, nicotinic acid and trace elements such as manganese, zinc and chromium, which are necessary for human growth and development.
Brown sugar is also a good medicine for women Eating a proper amount of brown sugar every day for postpartum women can not only increase all kinds of nutrients needed by the body, but also have the effect of enriching blood and benefiting qi. In addition, eating brown sugar also has the effects of promoting blood circulation, relaxing muscles and tendons, warming spleen and strengthening stomach, removing blood stasis and promoting regeneration.
Brown sugar is the surplus product of white sugar production. Although it retains a lot of nutrients, it also contains some impurities. Therefore, eat brown sugar in moderation, not directly, and it is best to burn it into brown sugar water to drink.
Eat brown sugar in moderation every time to avoid affecting appetite and digestion and absorption of gastrointestinal tract. Both white sugar and brown sugar are extracted from sugarcane and beet, and the main chemical component is sucrose.
Brown sugar is not very pure. The purity of sucrose is about 96%, and it contains a small amount of minerals, vitamins, protein, cellulose and other ingredients. The sucrose purity of white sugar is 99.9%. Because it is too pure, the content of other nutrients is very small and the nutritional value is very low. Rock candy is a crystal copy of sugar. There are white, yellow, red, crimson and other colors, and the crystal is ice-like, hence the name rock sugar.
White sugar, rock sugar and brown sugar are all extracted from sugar cane and sugar beet, and all belong to the category of sucrose. Brown sugar is a mixture of sucrose and molasses, and white sugar is made from brown sugar through washing, centrifugation, honey separation and peeling. Rock sugar is formed by recrystallization of white sugar under certain conditions. Their main chemical component is sucrose. In other words, the chemical composition of rock sugar and white sugar is exactly the same, but the crystallization conditions are different.
