White sugar is refined sugar made from molasses extracted from sugar cane and sugar beet, white sugar is white in color, clean and sweet. White sugar is easily contaminated with pathogenic microorganisms during production, packaging, transportation and storage. Especially stored for more than a year, the color of white sugar, often by the mite contamination. According to experiments, from 500 grams of sugar was detected 15,000 mites. If a person eats sugar contaminated by mites, the mites enter the digestive tract parasites, causing abdominal pain, diarrhea and other symptoms, and some even cause allergic reactions. If infants or the elderly in the food, directly add this contaminated raw sugar, can be due to choking and coughing and other mites into the lungs and cause asthma or hemoptysis, and easy to complicate bronchitis or pneumonia.

People (especially babies, young children and the elderly) eat food, do not dip in raw sugar to eat. The correct way to eat is to heat it at high temperature for 3 to 5 minutes before eating

Appropriate consumption of white sugar can help improve the body's absorption of calcium; however, too much will hinder the absorption of calcium. Rock sugar nourishes yin and promotes fluids, moistens the lungs and stops coughing, and has a good auxiliary therapeutic effect on lung dryness and cough, dry cough without phlegm, and sputum with blood. Although brown sugar has more magazines, the nutrients are better retained. It has the benefit of gas, slow in the middle, help the spleen to food, blood to break the effects of silt, but also with the role of dispersal of cold and pain. Therefore, women due to cold body weakness caused by menstrual cramps or post-partum drink some brown sugar water is often effective

"Brown sugar" is the raw material of sugar cane, containing about 95% of the sucrose, the ancient method of harvesting down the sugar cane through the chopping and crushing, pressing out the juice first to remove dirt, bacteria, fiber and other impurities, followed by a small fire boiled for 5 to 6 hours, stirring to let the water slowly evaporate, so that sugar concentration gradually increased, high concentration of sugar, and the sugar is gradually increased. The concentration of the sugar gradually increases, and the highly concentrated syrup will solidify into solid lumps of crude sugar, also known as brown sugar bricks, after cooling. This traditional practice maintains the original nutrition of sugarcane, and at the same time gives brown sugar a special flavor similar to that of caramel. The longer it is boiled during the production process, the darker the color of the brown sugar bricks become, making the brown sugar appear in different shades of reddish brown. The traditional powdered brown sugar is made by grinding the brown sugar bricks.

SUGAR CANDY

1. Overview: Brown sugar is made from white granulated sugar, which is re-solubilized, purified and recrystallized.

(1) varieties: rock sugar is divided into two kinds of monocrystalline rock sugar and polycrystalline rock sugar, the former is also known as granular rock sugar, the 60's by the tianjin xinhua food factory was first developed successfully, opened up the international market, become the first domestic export manufacturers. The latter, also known as box rock candy, is made of multiple crystals and polymerization of sucrose crystals, is China's traditional products. From the variety of rock candy is divided into white rock candy and yellow rock candy two kinds of exports to white rock candy, yellow rock candy export quantity is very small.

(2) use: crystal sugar quality is pure, not easy to deteriorate, in addition to candy can be eaten, but also can be used for advanced food sweeteners, preparation of medicines impregnated with alcohol and tonic medicine and so on.

2. Processing:

(1) single crystal rock sugar: sugar into the right amount of water heating and dissolving, filtered into the crystallization tank, so that the sugar solution reaches supersaturation, put into the crystal seed to raise the crystal, to be raised to a large crystal grain taken out for dehoneying and centrifugal drying, drying through the ventilation, sieving, grading and packaging after the shipment.

(2) polycrystalline rock sugar: white granulated sugar into the right amount of water to heat and dissolve, cooking sugar, to reach a certain concentration into the crystallization basin, in the crystallization chamber after a week of crystallization, take out the mother liquor to control the end of the sand bottom knocked out after drying, mixing and packaging factory.
