Question 1: What is the function of sorbitol? Use and efficacy

General introduction

Sorbitol is a widely used chemical raw material, which is widely used in food, daily chemical, medicine and other industries. It can be used as sweetener, humectant, excipient, preservative and so on. At the same time, it has the nutritional advantages of polyol, that is, low calorific value, low sugar, anti-caries and other effects.

food industry

The application of sorbitol in food industry is hygroscopic, so adding sorbitan to food can prevent food from cracking and keep food fresh and soft. When used in bread and cake, it has obvious effect. The sweetness of sorbitol is lower than that of sucrose, and it is not used by some bacteria. It is a good raw material for producing sweet candy snacks and an important raw material for producing sugar-free candy, and can be used to process various foods for preventing dental caries. Sorbitol contains no aldehyde group, is not easy to be oxidized, and does not produce Maillard reaction with amino acids when heated. It has certain physiological activity, and can prevent the denaturation of carotenoids, edible fat and protein. Adding sorbitol to concentrated milk can prolong the shelf life, improve the color and flavor of small intestine, and has obvious stable and long-term preservation effect on fish paste. It also has the same effect in jam preserves. The metabolism of sorbitol does not cause the increase of blood sugar, so it can be used as a sweetener and nutrient for diabetic food.

Question 2: What is the use of sorbitol? Sorbitol has moisturizing property, which can replace glycerol and be used in the production of toothpaste, cigarettes and cosmetics. Using sorbitol and propylene oxide as raw materials, polyurethane rigid foam with certain flame retardant properties can be produced. In food industry, it can be used as sweetener, humectant, chelating agent and tissue modifier. In the pharmaceutical industry, sorbitan ester produced by nitration of sorbitol is a drug for treating coronary heart disease. Food additives, cosmetic raw materials, organic synthetic raw materials, humectants, solvents, etc. Nutritional sweeteners, wetting agents, chelating agents and stabilizers. It is a special sweetener with moisturizing function. Diuretic and dehydrating agent. It can be used for the treatment of brain edema and intracranial hypertension, for the treatment of glaucoma with increased intraocular pressure, and for edema and oliguria with normal cardiac and renal functions. It can also be used as a raw material for the production of vitamin C. Sorbitol can be produced by fermentation and chemical synthesis. It can also be used as the raw material of industrial surfactants to produce surfactants such as Span and Tween.

Question 3: What food contains sorbitol ice cream, cakes, drinks, candies, toothpaste and other products? But it doesn't mean that all these products contain sorbitol.

Question 4: What is sorbitol? Will people eat food containing sorbitol have any harm? Sorbitol is a new sweetener made from high-quality glucose by hydrogenation, refining and concentration. After sorbitol enters the human body, it first diffuses slowly, and the oxidized sugar is reused to participate in fructose metabolism, which has no effect on blood sugar and urine sugar, and can be used as a sweetener for diabetics. It has good moisture retention, acid resistance and non-fermentation, and can be used as sweetener and humectant.

It has good moisture retention, acid resistance and non-fermentation, and can be used as sweetener and humectant.

Sorbitol is less sweet than sucrose, and is not used by some bacteria, so it can be widely used in food, leather, cosmetics, paper, textile, plastics, toothpaste, rubber and other industries.

Question 5: What is the use of sorbitol and its application in chemical industry?

Using sorbitol and propylene oxide as starting materials, polyurethane rigid foam can be produced and has certain flame retardant properties. Esters formed by sorbitol and synthetic fatty acids can replace linseed oil and be used to produce alkyd resin paint instead of oil. Sorbitol rosin ester is a common raw material for building coatings. Sorbitol ester is used as plasticizer and lubricant in PVC resin and other polymers. Sorbitol is complexed with iron, copper and aluminum ions in alkaline solution and applied to bleaching and washing in textile industry. Application in food industry

It also has the same effect in jam preserves.

Textile and printing industries In the textile industry, the addition of sorbitol contributes to the printing and dyeing of fabrics. Sorbitol used in papermaking industry can make paper smoother and print more clearly; The use of sorbitol in packaging paper will make the packaging paper more elastic and durable. It is mainly used as softener, humidity regulator and lubricant in daily chemical and light industry, and is widely used in toothpaste, emulsion, mouthwash, perfume, deodorant paste and other formulations. Sorbitol anhydride fatty acid esters synthesized by sorbitol dehydration and fatty acids are collectively called Span surfactants, and their polyoxyethylene derivatives are collectively called Tween surfactants. Span and Tween are called the third generation surfactants, which are usually used together, often as emulsifiers, and rarely have * * * effects on the skin.

Application of sorbitol in crystallization inhibitor, cryoprotectant and stabilizer of traditional Chinese medicine preparation; both sorbitol and mannitol are hypertonic dehydration diuretics with the function of expanding extracellular fluid volume. According to China Pharmacopoeia, mannitol infusion for clinical use is 20% supersaturated solution. Mannitol is easy to crystallize and separate out when it is infused below 20℃, but the room temperature in most areas of China is below 20℃ in winter. It needs to be preheated to dissolve it before taking it, which not only causes difficulties in clinical medication, especially emergency medication, but also easily causes suspicion of patients and conflicts between doctors and patients. Adding proper amount of sorbitol in the production of mannitol infusion to prepare compound mannitol infusion can prevent the crystallization of mannitol, and the effect is the same. The new dosage form of cryoprotectant Neupogen (human granulocyte colony factor) approved by the United States, that is, sorbitol is used instead of mannitol as a protectant in its preparation, which can keep the biological activity of Neupogen in the frozen environment. At present, the price of mannitol is 3-5 times that of sorbitol (up to 10 times at the highest). Using sorbitol instead of mannitol can achieve the same effect, which not only reduces the cost, but also has a wider source of raw materials. With the rapid development of genetic engineering, a large number of gene factors need to be protected, and sorbitol will be more widely used in this field. Stabilizer of Chinese traditional medicine preparation The Chinese traditional medicine products successfully developed in recent years, such as Shuanghuanglian oral liquid, Shuanghuanglian powder injection, Angong Niuhuang pill and Qingkailing infusion, have the characteristics of convenient use of western medicine. Adding a small amount of sorbitol can stabilize the drug effect and prevent precipitation. Sorbitol medicine industry sorbitol has the characteristics of diuresis and dehydration, which can reduce intracranial pressure and prevent edema. It can be directly used as a drug for brain edema and glaucoma. It is also used for edema and oliguria with normal heart and kidney function; Oral administration can be used as laxative or sucrose substitute for diabetic patients. Clinical preparations include sorbitol injection, iron sorbitol injection and compound amino acid injection. (1) sorbitol injection crystalline sorbitol was dissolved, filtered and sterilized to make sorbitol injection. Clinically used for brain edema and glaucoma. A small part of sorbitol is converted into glycogen in human body, and most of it is not metabolized, and it is excreted through renal tubules in its original form. After intravenous drip of sorbitol, the osmotic pressure of plasma can be increased, the tissue can be dehydrated, and it can hardly be reabsorbed by renal tubules after glomerular filtration, which plays a diuretic role. Sorbitol, as a diuretic, has a slightly worse curative effect than mannitol, but its solubility is large, and it is prepared at the same concentration as mannitol [20g? (100mL)- 1], which is not as easy to crystallize as mannitol at low temperature and is easy to use. (2) Iron Sorbitol Injection is an anti-anemia drug, which is ... >; >
