Refined sugar, unlike simple granulated sugar, has a high degree of purification. Producers supply sugar to trade in various forms: powdered, sand or pressed. The technology by which refined sugar is obtained is simple; beet or cane material is used as a raw material. Finished products from both varieties of the starting material taste almost the same, but the cost is different. Cane refined sugar is more expensive and takes longer to produce.

The essence of the process of obtaining a purified product is to prepare a saturated solution, which is then transferred to a syrup state for further adsorption and thorough filtration. After the resulting mass is placed in a vacuum device, where it is brought to a state of complete condensation. In order for it to acquire a snow-white color, it is treated with a suspension of ultramarine (food coloring).

At the next stage, refined sugar can be produced in two ways, depending on the method of obtaining the final product - cast or pressed. The first option is more expensive and complex. With it, refined sugar is obtained by pouring the mass (mass mass) into specialized forms,where she slowly freezes. To remove the molasses, a solution of purified sugar is poured on top, this procedure is repeated three to four times. As a result of processing, the finished product is removed from the molds and divided into cubes of the required size. It is much easier and cheaper to get refined sugar in a compressed way, when the syrup is bleached in a special centrifuge. The substance obtained as a result of the operation is pressed and dried, then dividing the solid mass into parallelepipeds.

As a rule, the quality of the product is assessed by organoleptic methods, by which the taste, smell, color, and transparency of the solution are determined. The color of the refined substance should be white, spotless and clean, there may be a bluish tint. The taste is sweet, without foreign flavors, the same applies to the smell. The solution should be free of impurities, sediment and be clear or slightly opalescent. Among the physico-chemical properties, the most important are:

- mass fractions of sucrose, moisture, reducing substances;

- content of ferrous impurities;

- chromaticity;

- fortress.

Various microbiological characteristics are also important: yeasts, pathogens, fungi, MAFAM, BGKP3. The content of pesticides (phostoxin, hexachloran) and toxic substances (arsenic, cadmium, lead, mercury, copper, zinc) is monitored. Pack the product in the form of sand and powder in bags, and lump sugar - in boxes or individual bags (2 pieces each in subparchment and artistic wrapper).

Transportation andstorage of refined sugar is carried out in containers or in covered vehicles. Wagons, holds, containers should not have gaps and be dry, the roof should not let moisture through, doors and hatches should be tightly closed. The product must be stored at a humidity of no more than 70% and a temperature of no higher than 40 ° C, always separately from other substances and materials.
