Product introduction:

Glycerol, also known as glycerol, has the chemical formula C3H8O3. It is colorless, odorless, sweet and has a clear, viscous liquid appearance. It is an organic matter that can absorb moisture from the air, hydrogen sulfide, hydrogen cyanide and sulfur dioxide. It is insoluble in benzene, chloroform, carbon tetrachloride, carbon disulfide, petroleum ether and oil, and is the skeleton component of triglyceride molecule.

Production method:

The industrial production of glycerol can be divided into two main categories: the method of using natural oil as raw material, the glycerol obtained is called natural glycerol; Glycerol obtained by the synthesis of propylene as raw material is called synthetic glycerol.

Natural glycerin

Before 1984, glycerol was completely recovered from the by-products of soap made from animal and plant fats. Up to now, natural oil is still the main raw material for glycerol production. About 42% of natural glycerol is produced by homemade soap and 58% is produced by fatty acids. Saponification of fats in soap making industry. The saponification reaction product is divided into two layers: the upper layer is mainly containing sodium fatty acid (soap) and a small amount of glycerol, the lower layer is waste lye, containing salt, sodium hydroxide glycerol dilute solution, generally containing glycerol 9-16%, inorganic salt 8-20%. Grease reaction. Glycerin water (also known as sweet water) obtained by oil hydrolysis has a higher glycerin content than soap waste liquid, about 14-20%, and inorganic salt 0-0.2%. In recent years, continuous high pressure hydrolysis method has been widely used, the reaction does not use catalyst, the resulting sweet water generally does not contain inorganic acid, the purification method is simpler than waste lye. The amount of glycerin contained in soap waste liquid or glycerin water obtained by grease hydrolysis is not high, and all contain various impurities. The production process of natural glycerin includes purification, concentration to crude glycerin, and refining process of crude glycerin distillation, decolorization and deodorization.

Product use:

The best quality of edible glycerol is biorefined glycerol, which is a polyol glycerol, containing reducing sugars such as glycerol and glucose in addition to glycerol. In addition to moisturizing and moisturizing functions, it also has special effects such as high activity, antioxidant and alcoholizing.

Each gram of glycerin, fully oxidized, produces 4 kilocalories and is absorbed without altering blood sugar or insulin levels. Glycerin is a commonly used sweetener and moisturizing agent in the food processing industry, mostly found in sports food and dairy substitutes.

A. Application in fruit juice, fruit vinegar and other beverages

Different quality fruits contain different levels of tannin, which is the source of bitter and astringent taste in fruits.

Addition: 1%

C. Application of meat jerky, sausage and cured meat industry

Preserved products, jerky meat, sausage usage:

In processing and production, dilute the plant refined glycerin with pure grain wine above 50 degrees, evenly spray on the meat or cut meat, thoroughly knead or stir.

Function: Lock water, moisturizing, achieve weight gain effect, extend the shelf life.

Addition amount: 1.2%~1.5% [3]

D. Application of preserved fruit industry

Preserved fruit in processing, because of storage problems make the product easy to lose water, dry hard, fruit also contains tannin.

Function: lock water, moisturize, inhibit tannin heteroplasia, achieve color protection, preservation, weight gain effect, extend shelf life.

Addition amount: 0.8%~1%
