White sugar, rock sugar and brown sugar are all extracted from sugarcane and sugar beets and all belong to the category of sucrose. It is separated according to the degree of refinement, source, form and color of the sugar.

1, white sugar.

White granulated sugar is a kind of table sugar. Its particles are crystalline, uniform, white color, pure sweetness, sweetness is slightly lower than brown sugar. It is commonly used in cooking. Appropriate consumption of white sugar has the effect of tonifying the middle and benefiting the qi, harmonizing the stomach and moistening the lungs, nourishing the yin and stopping sweating.

GB 13104-2014 white sugar is defined as sugar cane or sugar beet as raw material, by extracting the sugar juice, clean processing, cooking and refining crystallization and separation of honey and other processes made of sucrose crystals. Mian Bai Sugar is in powder form, suitable for cooking purposes, and has a sweetness similar to that of white granulated sugar. There are two kinds of white sugar: refined white sugar and white sugar made by local law. The former white color, crystal grain fine soft, good quality; the latter color yellowish slightly dark, poor quality.

White sugar is the most important varieties of sugar, basically 100% of the edible sugar in foreign countries are white sugar, white sugar in the country accounted for more than 90% of the total amount of sugar. White sugar is divided into refined, superior, first-class, second-class.

2, brown sugar.

Brown sugar refers to finished sugar cane sugar with honey, sugar cane by juicing, concentrated sugar with honey formed. Brown sugar is divided into sheet sugar, brown sugar powder, bowl sugar and so on according to the different crystallization particles, because it is not highly refined, contains almost all the ingredients in the cane juice.

Specific production process:

(1) from the cane to brown sugar is a physical process, there is no chemical change process;

(2) the cane water out of the pot heating ??? system to evaporate the water, the rest is brown sugar;

(3) all the production process, only in the process of heating this process to add a little right to the child oil (a kind of right to the child tree knot nuts extracted). The nuts of the tree knot out of the oil), some of the poorer people will use the cheaper leizi oil instead;

(4) there is a process is very important, that is, if you directly will be 滶 made of brown sugar cooling, is the so-called "kraft sugar", cold kraft sugar you can't possibly bite with your teeth, but also not possible to use a knife to cut the move, in a word you can't eat it to put the 滶 made of brown sugar in a large wooden bowl with a diameter of about more than 2 meters in diameter in a large wooden basin stirring until cooled, the liquid brown sugar will become the brown sugar we see on the market.

3, rock sugar.

Icing sugar is white granulated sugar decocted into ice-like crystals, is made from sucrose plus protein raw material formulations, by re-soluble, clean processing and recrystallization of large particles of crystalline sugar, there are single crystals and polycrystalline two kinds of transparent or semi-transparent shape.

Because of its crystallization, such as ice, so the name rock candy, also known as "ice grain". Naturally occurring rock candy is white, yellowish, grayish, etc. In addition, there are various types of colored rock candy (mainly for export) with added food coloring, such as green, blue, orange, reddish, crimson and other colors.

In addition, proper consumption of white sugar can improve the body's absorption of calcium, although if it is too much, it will affect the absorption of calcium.

White sugar, after all, is refined, the nutrients in it are already very little, and white sugar sugar is high in sugar, when consumed, try to control the dosage, so that the body will be better.

2, the role of rock candy: generally speaking, rock candy is suitable for spring and fall consumption. Because rock candy is flat and cool, can clear lung heat, have nourishing Yin, moistening the lungs to stop the effect of cough, lung dry cough, dry cough without phlegm, sputum with blood have a good auxiliary therapeutic effect. This is also why the guys will choose rock sugar stewed avocado to cough, rather than brown sugar or white sugar stewed avocado reason.

People who usually have throat discomfort and laryngitis can also contain a piece of rock sugar to relieve throat discomfort. In addition, rock sugar also has the effect of tonifying the middle and benefiting the qi, which is very suitable for brewing various medicinal wines.

Although rock sugar is from white sugar, the composition of the body after decomposition is the same as white sugar, but it has the therapeutic effect that white sugar does not have, therefore, its therapeutic value is much higher than white sugar. Overall, there is no contraindication to rock sugar, and it can be consumed by the general public.

3, the role of brown sugar: brown sugar is suitable for summer and winter consumption, it retains almost all the nutrients in the sugar cane juice or beet juice, such as rich vitamins and trace elements (iron, zinc, manganese, chromium, etc.), they are particularly easy to be digested and absorbed by our body, which is white sugar can not be replaced.

Brown sugar is rich in nutrients, and in addition to replenishing the energy and trace elements needed by our bodies, it can also invigorate blood circulation, dissolve blood stasis, drive away cold, relieve pain, warm the spleen and strengthen the stomach, and is thus especially suitable for the elderly and weak, people who have recovered from serious illnesses, and people with poor spleen and stomach.
