What raw materials are rock sugar made of?

What raw materials are rock sugar made of? The sweet taste of rock sugar is a healthy diet suitable for all ages. Sweet rock sugar is the favorite of many children. , rock sugar can also be added to your daily diet. Let’s share with you what ingredients rock sugar is made from. What raw materials are rock sugar made from? 1

Rock sugar is made from white sugar, which is re-dissolved, purified and recrystallized.

Rock sugar can be made from refined syrup, an intermediate product in the refining workshop of a refined sugar factory, or from white sugar, which is made through re-dissolving, cleaning and recrystallization production processes. It is available in white, It is yellowish, reddish, deep red and other colors, and crystallizes like ice, so it is called rock sugar.

Because rock sugar is composed of glucose containing crystallized water, which is the same as white sugar that is decomposed in the body, it can replace white sugar; and because it has a higher purity and has its own unique therapeutic effects, it It is better than white sugar and quite competitive in the market.

Rock sugar, like brown sugar, white sugar, and brown sugar, are all refined from sucrose, because rock sugar has the highest purity during the production process and does not have the same harmful effects as other sugars. It has a sour taste, so everyone thinks that rock sugar is better, but because rock sugar has the highest purity, there are relatively fewer nutrients called impurities.

Rock sugar is better than white sugar: the reason is that rock sugar is made from white sugar as raw material, which is dissolved, filtered, boiled and crystallized. Its purity is higher. White sugar is purified directly from sugar cane juice or purified from raw sugar. Furthermore, long-term consumption of rock sugar water can effectively reduce internal heat, lower blood pressure, and provide the body with the glucose components it needs.

The difference between rock sugar and white sugar is: one is crystal and the other is fine granular wet powder. The sugar content of the two is the same. There is nothing better or worse. It is just a matter of taste. Generally, healthy people eating sugar in an appropriate amount is good for their health. People with diabetes should eat less or not at all. What raw materials are rock sugar made from? 2

Rock sugar is an ice cube-shaped crystal made by decoction of white sugar. It is made from sucrose plus protein raw material formula, re-dissolved, cleaned and then recrystallized. Large crystalline sugar, transparent or translucent.

Rock sugar is divided into the following categories:

1. Single crystal rock sugar

It is in the shape of regular transparent crystals and is a new type of rock sugar produced in the 1960s. . Its production process is: divided into grades.

2. Polycrystalline rock sugar

Also known as old rock sugar, earth rock sugar, lump rock sugar, etc., it is irregular crystal rock sugar produced by traditional technology. Depending on the production process, rock sugar is divided into hanging thread method (the finished product is divided into icicles and ice edges, and there will be impurities such as cotton thread, paper, etc.) and basin crystal method (all the rock sugar is crystallized along the crystallization basin, and the finished product is relatively pure). According to different colors, it is divided into white rock sugar, yellow rock sugar, and amber rock sugar (gray).

3. Health-care rock sugar

In the production process of traditional polycrystalline rock sugar, new rock sugar with health-care functions is produced by adding some auxiliary ingredients with health-care functions. The more common health rock sugar includes pear juice rock sugar, chrysanthemum rock sugar, lily rock sugar, green tea rock sugar, etc.

Things to note when purchasing rock sugar:

There are basically three types of rock sugar on the market. One is relatively white in color, not too transparent, one by one; the other is very white in color and very transparent, which should be the best-looking in terms of appearance; and the last one is slightly tinged. Large pieces of light yellow rock sugar, this kind of rock sugar is also called soil rock sugar, and the production process is relatively traditional.

Of the three types mentioned above, the first one has a low sulfur dioxide content and can be eaten; the second one has a sulfur dioxide content that obviously exceeds the standard and will cause harm to the human body after consumption; it is recommended to choose the third one. Three kinds of rock sugar, this kind of rock sugar is the safest.

Although this kind of slightly yellowish large rock candy looks unsightly, it uses traditional techniques and generally does not add sulfur dioxide. What is rock sugar made of? 3

1. What is rock sugar made of?

There are many kinds of sugar, rock sugar is the most common. Because it crystallizes like ice, it is called It is called rock sugar, and its ingredient is glucose containing crystal water, which can replace white sugar.

What are the raw materials of rock sugar?

1. Generally, rock sugar is made from white sugar. White sugar and water are stirred and dissolved to form a sugar liquid. Common rock sugar is obtained through production processes such as clarification and recrystallization.

2. In addition to white sugar, refined syrup, an intermediate product in the refining workshop of a refined sugar factory, can also be used as a raw material for the production of rock sugar.

2. How rock sugar is made

There are two main methods of making rock sugar, traditional local production and modern large-scale production technology. , the following is an introduction to you:

1. Making rock sugar by local methods

(1) Prepare sugar liquid: 50kg of white sugar, add 10kg of water, stir evenly to fully dissolve the sugar in the water.

(2) Boil: Add vegetable oil to the interlayer of the jacketed pot, pour the prepared sugar liquid into the upper pot, and simmer over fire; when the sugar liquid boils for 5-6 minutes, Add 0.5 kg of saturated alum solution at room temperature and stir while adding to mix thoroughly; when the temperature in the sugar solution rises to 150°C, stop the fire and cool down and remove from the pot.

(3) Crystallization: Put the sugar liquid out of the pot into a plate and place it on the pit. The temperature in the plate will be kept at about 90°C that day, and then the temperature will drop by 10°C every day until it drops to the seventh day. Rock sugar can be obtained (if the temperature is not enough, you can add fire to increase the temperature of the pit).

2. Modern rock sugar production technology

(1) Syrup concentration: The syrup mother liquor used to make rock sugar is injected into the evaporation tank, and 0.3Mpa saturated steam is introduced, so that the boiling point of the syrup is 112 Evaporate and concentrate within the range of -114℃. When the syrup evaporates water and reaches 82-84°Bx, the concentration process ends.

(2) Rock sugar crystallization: At a temperature of 112°C, the syrup in the evaporation tank is injected through the pipeline by pressure and placed in the crystallization chamber. The crystallization chamber is equipped with a steam heater and a warmer. , thermometer and hygrometer, used to control the indoor temperature and humidity during the crystallization period. The temperature is kept at 70-80°C for the first and second days, and the relative humidity is kept at 80;

The temperature is kept at 65-65 for the third and fourth days. 70℃, relative humidity 70; the temperature is maintained at 55-65℃, relative humidity is 60-65 on the fifth and sixth days; the temperature is maintained at 40-5O℃, relative humidity is about 50 on the seventh and eighth days; crystallization is opened on the ninth day Open the door of the room, lower the humidity and temperature, and then exit the room to control the slurry.

(3) Slurry control: Concentrate the rock sugar mother liquor in the barrel into the mother liquor storage tank, and then pump it to the syrup storage tank in the yellow sugar workshop for boiling sugar; the crystallized rock sugar in the barrel And the remaining small amount of mother liquor is placed upside down on the grid of the empty slurry tank, and the mother liquor in the rock sugar is drained and recycled; depending on the specific situation, decide whether to spray warm water to wash the mother liquor on the crystal surface.

(4) Drying: The rock sugar in the barrel is put into the drying tray to manually crush the rock sugar crystals appropriately. There is a quality difference between the rock sugar in the middle and the bottom of the crystallization barrel, and manual sorting is required. The rock sugar drying tray is sent into the tunnel dryer, where it is forced to dry by blowing hot air from the blower and extracting moisture from the induced draft fan.

(5) Packaging: The dried rock sugar is transported to the packaging room for packaging.
