How do you make rock candy?

[cooking method]: before cooking, add vegetable oil to the sandwich pot, then pour the prepared sugar solution into the upper pot and boil it over fire. When the sugar solution boils for 5 to 6 minutes, add 0.5 kg of saturated alum solution at room temperature and stir to make it mix fully.

The processing method of rock sugar is composed of sucrose and protein raw material, and the large crystalline sugar is prepared by recrystallization after re-dissolution and clean treatment. there are two kinds of crystal sugar, single crystal and polycrystal, which are transparent or translucent. Different from brown sugar, white sugar and yellow sugar, brown sugar is different from brown sugar: sugarcane as raw material.

It is an irregular crystal rock candy produced by traditional technology. Light brown, amber rock sugar (gray), central separation to form sugar crystallization, yellow rock sugar, sugar beet as raw materials (one-step method) or raw sugar as raw materials (two-step method): heat and dissolve white granulated sugar in proper amount of water.

Polycrystalline rock sugar: the white granulated sugar is heated and dissolved in an appropriate amount of water, and the sugar is boiled. After reaching a certain concentration, it is input into the crystallization basin. After a week of crystal growth in the crystallization chamber, the mother liquid is taken out and the sand bottom is removed, crushed and dried, and then mixed packing leaves the factory.

Then tie a piece of sugar with cotton thread and put it in saturated sugar water. Tie chopsticks to your head instead of fixing it by hand. Wait for the water temperature to drop and the sugar will slowly precipitate, and your little sugar will crystallize and grow bigger and bigger. The industrial principle is the same as this, of course, there are some special ways to improve efficiency.

To make technical sugar solution by local method, select white sugar 55kg, add clean water 1 and stir, so that the sugar can fully dissolve the strong electrolyte. Before cooking, add cooking oil in the compartment of the cooking pot, then pour the sugar solution into the top pot and boil the material with fire.

How is rock candy made?

Rock sugar is made by dissolving white granulated sugar into liquid, firing, removing impurities, and then evaporating water, so that it can be naturally crystallized at about 40 ℃, or frozen. The crystal grain of high quality rock sugar is uniform, the color is clear and white, translucent, crystal luster, sweet taste, no obvious impurities, no peculiar smell.

Single crystal rock sugar: the white granulated sugar is heated and dissolved in an appropriate amount of water, filtered and input into the crystallization tank to make the sugar solution supersaturated, put into the crystal seed to nourish the crystal, take out the nectar and centrifugal dry after the grain is grown, ventilated and dried, sifted and packaged out of the factory.

Rock sugar is made from white granulated sugar, which is redissolved, cleaned and recrystallized. sugar cane can also be used as raw material, sucrose plus protein raw material formula, after steam cooking and static crystallization, rock sugar is the crystallization re-product of granulated sugar 2. The naturally generated rock sugar has white, yellowish, light gray and other colors, in addition, there are also on the market.

In a word, the production process of rock sugar includes raw material preparation, purification treatment, evaporation concentration, crystallization, separation, washing, drying, screening and classification, packaging and quality inspection. Through these technological steps, sucrose from sugarcane or sugar beet can be extracted and made into rock sugar with large particles and high purity.

How is rock candy made? Is there any difference between brown sugar, white sugar, brown sugar and it?

1. First of all, the names are different, ha. Brown sugar, white sugar and rock sugar all come from sugar cane. Brown sugar is made first, then refined into white sugar, which is dehydrated and crystallized into rock sugar. Secondly, the three sugars are different in nutritional application. Brown sugar is hot, brown sugar ginger soup can go cold, cure cold.

2. Brown sugar is also extracted from sugarcane. The biggest difference between brown sugar and white sugar is that the degree of refinement is lower than that of white granulated sugar. Brown sugar is the sugar obtained by direct drying of sugarcane after juice extraction, which is only preliminarily refined and purified, even without refining and purification, so it is also called raw sucrose.

3. The difference between white sugar, brown sugar, black sugar and yellow sugar: they are all made from sugar beet and sugarcane. It's mainly due to different colors. White sugar is obtained from sugarcane and sugar beet after juicing, filtration, impurity removal, clarification, vacuum concentration and boiling, honey removal, sugar washing and drying.

4. Black sugar and yellow sugar also belong to brown sugar, its color is different, just because the temperature and time in the extraction process are different. White sugar is extracted from brown sugar. In the process of extraction, the color and sundries are removed and become white and pure, but at the same time, some rich nutrients in brown sugar are discarded.

Question 1: rock sugar is better than white sugar, can you eat more? In the eyes of many people, rock sugar is higher than white sugar, white sugar can not eat more, but rock sugar can. Wrong! Tell you, whether it is brown sugar, white granulated sugar, cotton white sugar, or rock sugar, their essence is sucrose, but there is a slight difference in purity, they should be eaten in moderation.

How is rock candy made?

Rock sugar is made from white granulated sugar by re-dissolving, cleaning and recrystallization. (1) varieties: rock sugar is divided into single crystal rock sugar and polycrystal rock sugar, the former is also known as granular rock sugar, which was first successfully developed by Tianjin Xinhua Food Factory in the 1960s, opened up the international market and became the first domestic exporter.

Rock sugar is an ice-like crystal made from white granulated sugar. it is a large grain of crystalline sugar made from sucrose and protein raw material formula, which is recrystallized after re-dissolution and clean treatment, which is transparent or translucent.

Add water in the technological process: add 100 jin of sugar and 35 jin of water to stir evenly to make the sugar dissolve. Boil: before cooking, add vegetable oil, soybean oil, vegetable oil and peanut oil to the interlayer, or refuel in a large pot, and a small pot in a large pot (need to be propped up, do not touch the bottom of the pot, so as to avoid scorching the sugar).

In a word, the production process of rock sugar includes raw material preparation, purification treatment, evaporation concentration, crystallization, separation, washing, drying, screening and classification, packaging and quality inspection. Through these technological steps, sucrose from sugarcane or sugar beet can be extracted and made into rock sugar with large particles and high purity.

The raw material rock sugar is usually made from sucrose (granulated sugar). In the production process, rock sugar is melted into liquid with white granulated sugar, fired, removed impurities, and then evaporated water, so that it can be naturally crystallized at about 40, or frozen.

Rock sugar is usually made from sucrose (granulated sugar). First, sucrose is made into an aqueous solution, precipitated and filtered to remove impurities, heated and evaporated so that the sugar water is concentrated to a saturated solution state, and small rock sugar particles are put into the crystal nucleus. As the solution temperature continues to drop, large pieces of rock sugar are crystallized.
