corn starch is also called corn starch. The common name is Liugu powder. White powder with a slight yellowish tinge. It is made by soaking corn with .3% sulfurous acid, crushing, sieving, precipitating, drying and grinding. Ordinary products contain a small amount of fat and protein. Strong hygroscopicity, up to more than 3%. Product use

starch sugar

starch sugar (including glucose syrup, malt syrup, high fructose syrup containing 42% fructose, high fructose syrup containing 55% fructose, and medical crystalline glucose, etc.) is the largest product in starch deep processing. Mainly food additives, but also industrial raw materials, as a raw material of downstream products, such as glucose, maltose, high-fructose syrup, which are used for food, and starch sugar can be used as sorbitol, and can also be made into amino acids, which is also the upstream raw material of downstream products, and the demand in this respect is also considerable. Compared with sucrose, starch sugar is still very competitive in terms of health care, practicality and cost, and this space is still very large.

Starch sugar is easily digested and absorbed by human body and is an important nutrient. In addition, they have physiological functions that are beneficial to the human body that sucrose can't. Glucose, malt sugar and fructose can be hydrotreated to obtain sorbitol, malt sugar alcohol and mannitol respectively, which are collectively called polyhydric alcohols. Both pure fructose and polyhydric sugar alcohols have the characteristics of sweeteners and have been industrialized. The metabolic pathways of pure fructose and polyhydric sugar alcohols in human body have nothing to do with insulin, so they can be used as special sweeteners for diabetics. Because they are not used by oral microorganisms, they will not cause dental caries, so they are very suitable for children's food, sugar-free chewing gum and sugar-free candy, and because of their low energy values, they can be used to produce low-energy foods and prevent obesity. Functional sweeteners, which have been industrially produced, not only have the above advantages, but also directly enter the large intestine because they are not digested and absorbed by the human body, activating Bifidobacterium beneficial to the human body in the intestinal tract, promoting its growth and reproduction to inhibit the reproduction of harmful bacteria in the intestinal tract, thus protecting human health.

Polysugar alcohols have their unique uses, such as sorbitol's good thermal insulation; Hypotensive and diuretic properties of mannitol; Trehalose can improve the stress tolerance of organisms; These characteristics and price advantages make it have broad market prospects in the fields of molecular biology, medicine, food industry, cosmetics industry, agriculture and so on. In addition, microbial polysaccharides prepared by microbial action also have great uses. For example, xanthan gum is widely used in oil drilling, medicine and food because of its good shear resistance, salt resistance, acid and alkali resistance and high temperature resistance. Microbial polysaccharide cyclodextrin has the characteristics of adsorbing or embedding various organic compounds, which can keep the natural pigment of food, control the fishy smell of aquatic products, prolong the fragrance retention time as a carrier of essence, ensure the drug to be stable and not easy to decompose, etc., and also has great market potential. Other microbial polysaccharides, as well as pullulan, are promising products.

The main varieties of starch sugar in China are malt syrup, high malt syrup and glucose, which account for more than 8% of the starch sugar.

according to the physical state, starch sugar can be divided into solid and liquid. In 26, the output of solid starch sugar was 2.45 million tons, including 1.4 million tons of glucose, 45, tons of maltose essence and 3.15 million tons of liquid starch sugar, including 2.6 million tons of maltose syrup and 4, tons of fructose syrup. From the whole development situation, the development of solid starch sugar is higher than that of liquid starch sugar.

from p>21 to 25, the price of starch sugar fluctuated little. The price of starch sugar was calculated on the basis of crystalline glucose, and it was basically around 2,1-2,3 yuan/ton. In the second half of 25, with the growth of corn raw materials, the price of starch sugar rose slightly, fluctuating between 2,7-3, yuan/ton. Lysine is an essential amino acid that cannot be synthesized in animals and must be ingested from the outside. It is called the first restrictive amino acid, and its lack will affect the absorption of other amino acids. Therefore, with the development of feed industry and breeding industry, the demand for lysine is increasing. China is now the largest producer of lysine in the world. In 23/24, China imported a large amount of lysine from abroad, and then China became an exporter. The production of lysine in Dacheng Group alone has reached 35, tons, and the total amount of lysine in the world is 7, tons. The export of lysine in China has also brought some development space to the lysine industry in China.

monosodium glutamate (monosodium glutamate) is a flavor agent, which is widely used in catering industry and cooking seasoning. Asians have a soft spot for monosodium glutamate, and in some countries, the per capita annual consumption has reached more than 1 kg. China is a big producer of monosodium glutamate, with the output ranking first in the world, and the per capita annual consumption is only .5 kg, but it is not the lowest figure.

The amino acids produced from starch include isoleucine, arginine and methionine. The world demand for amino acids is growing rapidly. Organic acids produced from corn or starch include citric acid, lactic acid, malic acid, itaconic acid and oxalic acid. Citric acid is widely used in food industry, medicine industry, washing industry, textile industry and cosmetics industry, and its application in non-food industry is expanding day by day, so the world consumption has increased by 5% in recent 2 years. China ranks first or second in citric acid production in the world, but its export trade volume ranks first, with an annual export of about 2, tons. In the past, the production of citric acid in China mainly used dried potatoes as raw materials. Because of the high yield of corn raw materials, Taihua Factory has switched to corn raw materials, and there is a trend to switch to corn raw materials from the perspective of industry. Lactic acid is mainly used in food industry, accounting for about 5% of the total lactic acid. The world demand is 13,-15, tons, and it is still growing at the rate of 5-8%. Many countries develop biodegradable plastics of polylactic acid, and lactic acid has a great potential market for growth. Other organic acids are also developing trends in general.

modified starch

modified starch uses physical, chemical and enzymatic means to change the properties of natural starch to meet the needs of various industries. Modified starch is widely used. China has produced more than 7 varieties of pregelatinized starch, acidified starch, oxidized starch, etherified starch, esterified starch, cross-linked starch and grafted starch, which are used in textile, paper-making, food, petroleum, medical, construction, agricultural feed, daily chemical industry and other industries. Among them, the paper industry has the largest application amount, accounting for about 5-6% of the total. It is mainly used as wet end additive, interlayer or surface spray, surface sizing agent and coating adhesive. They significantly improve the physical strength of paper, improve the quality and grade, reduce the proportion of wood pulp, improve the retention rate of fine fibers and fillers, improve the ash, whiteness and opacity of finished paper, reduce wet end breakage, reduce the discharge of three wastes and improve printing performance.

the application of modified starch in food industry can keep the viscosity stability and thickening ability of processed food at high temperature, high shear force and low PH, and can also avoid water quality separation of processed food during storage at room temperature or low temperature. Because the transparency of starch paste is improved through modification, the appearance and luster of food can be improved. Therefore, modified starch can be added in the production of instant food, meat products, seasonings, yogurt, soup, candy, jelly, frozen food, bean paste stuffing, crispy snacks, snack foods, etc. to improve the product quality.

Modified starch is used in textile industry, mainly for sizing silk yarn and printing paste. In petroleum industry, modified starch is mainly used in various occasions of petroleum drilling fluid, fracturing fluid and oil and gas production. In short, modified starch has a wide range of applications, strong specificity and many varieties, and it is a product with great market potential and continuous development.

By 23, the output of modified starch in China was 45, tons, 6, tons in 25, 7, tons in 26 and is expected to exceed 9, tons in 27.

medicine

as far as the pharmaceutical industry is concerned, starch is the most important raw material in the antibiotic industry, because almost all antibiotics are produced by starch fermentation, such as penicillin, cephalosporin, tetracycline, oxytetracycline, chlortetracycline, streptomycin and various aminoglycoside antibiotics, all of which are made from starch by industrial microbial fermentation and extraction. In addition, another important use of starch is as a drug excipient. In the early days, most tablets produced by pharmaceutical factories in various countries used corn starch as filler and adhesive.
