The Ministry of Agriculture Rural Economic Research Center pointed out that in terms of China's domestic market, modified starch not only has a large market capacity, but also has a huge market potential. Coupled with its own advantages, cassava modified starch has strong market competition.
Starch-based modified starches are the largest branch of starch deep-processing products. At present, there are hundreds of products, which are widely used as functional raw materials in all walks of life to reduce production costs and improve products for various industries. Quality and grade, research and development of new products play a very important role. In the past ten years, the world’s production of modified starch has grown rapidly. At present, the annual output of modified starch in the world is close to 7 million tons, including about 3 million tons in the United States, more than 2 million tons in the EU, more than 300 million tons in Japan, and about 450,000 tons in Thailand. China has 350 thousand tons.
Because of the wide variety of product names, wide application, and high added value, the starch has been subjected to deep processing to produce various modified starches due to the existence of certain unfavorable characteristics of the original starch and the use of its strong variability, which has been referred to as Chaoyang Industry by some countries. "Or" gold industry" and entered the high-tech field.
Experts believe that in terms of China's domestic market, modified starch not only has a large market capacity, but also has a huge market potential:
From the viewpoint of the paper industry, modified starch is the main auxiliary material used for surface sizing and coating, and also used as an internal additive and cardboard interlayer adhesive to improve the properties of paper and increase the strength and smoothness of paper. Stiffness, wear resistance, durability, and retention of fillers allow paper and board to have good physical properties, surface properties, and meet specific quality requirements in other areas. China is a major papermaking country. At present, China's paper and paper products output is about 30 million tons, ranking third in the world. It is predicted that by 2005, it will exceed 40 million tons, and by 2010 it will reach 60 million tons or more. At present, the annual output of paper and paper products in the United States is 70 million tons, and 1.5 million tons of modified starch is used each year, accounting for about 2.1% of paper production. China currently has only 130,000 tons of modified starch for papermaking, which only accounts for 0.43% of paper production. According to the level of the United States, China's current use of modified starch for papermaking should be 600,000 tons, by 2005 it should reach more than 800,000 tons, and in 2010 it should exceed 1.2 million tons. With the adjustment of the product structure of the paper industry, that is, the proportion of medium- and high-grade paper products continues to grow, newsprint, cultural paper, office paper, copperplate paper, telecommunications paper, packaging paper and paperboard are long-term development varieties. The more amount of modified starch is added. In addition, due to the shortage of wood in China's paper industry, the supply of long-fiber wood pulp is insufficient, and only a large amount of annual grass fiber with short fibers, poor strength, and high number of heterocytic cells is used as raw material for papermaking raw materials. However, only short-fiber raw materials are used to produce high-grade paper products. The solution is to increase the amount of modified starch and other additives.
From the perspective of the textile industry, modified starches are used in warp sizing, dyeing, finishing and non-woven fabric composite products to obtain smooth, firm, thick, plump and other comprehensive feelings, which greatly improve the feel. In the past, chemical slurries were mainly used. Due to environmental pollution, they were gradually replaced by modified starches. China is a big textile country and its annual consumption of pulp is over 250,000 tons. If the United States meets the requirement of using 69% of the modified starch for pulp, China's textile industry needs only 17% of the stock annually. 50,000 tons.
From the perspective of the food industry, the use of modified starches has become more and more widespread. At present, there are more than 100 edible modified starches as thickeners, stabilizers, water retention agents, gelation agents, adhesives, anti-adhesion agents, and polishing agents. , Swelling agents, etc., used in canning, meat products, dairy products, candy, cakes, instant noodles, condiments, cold food, beverages and other products in the processing, but also through the application of modified starch consumption, so that more variety of food variety, new varieties emerge in endlessly. According to incomplete statistics, China currently has an annual output of about 1.5 million tons of snack foods, about 800,000 tons of candies, more than 4 million tons of beverages, more than 1 million tons of cakes, more than 2 million tons of cooked meat products, and about 600,000 tons of baked goods. Consumption of modified starch is more than 100,000 tons. At present, there are less than 50,000 tons of edible modified starch in the country, and the rest are imported. It is estimated that by 2010, the demand for edible modified starch in China will reach 300,000 tons or more. Taiwan Province has only 23 million people in China, but the annual consumption of modified starches amounts to more than 200,000 tons. Therefore, the potential market for edible modified starch is very considerable.
Judging from the aquafeed industry, modified starch is mainly used as a binder in feeds such as squid and soft-shelled turtle. The amount of modified starch is approximately 25% of feed. In recent years, China’s average annual consumption of aquatic feed is approximately 400,000 tons, and 100,000 tons of modified starch is needed. . In addition, the application and development prospects of modified starch for high-grade seafood are very broad.
From the point of view of building materials industry, with the rise of new building materials, modified starches have become more widely used in the building materials industry. At present, domestic use of a larger amount is used as adhesives for non-slurry wall structural panels, interior wall decorative adhesives, lightweight ceiling tile adhesives, and the like. It is estimated that by 2010, the modified starch for building materials in China will reach more than 100,000 tons.
From the perspective of the petroleum industry, modified starches are mainly used as fluid loss additives, fracturing fluid thickeners, demulsifiers, and the like. It is expected that by 2010, China's oil industry will use up to 50,000 tons of modified starch.
From the point of view of the pharmaceutical industry, modified starch is a good accessory and can be used as a diluent, absorbent, adhesive, wetting agent, disintegrant and the like. Only disintegrants consumed 15,000 tons of modified starch per year, and it is expected to reach 30,000 tons by 2010. In addition, modified starch is also widely used in clinical medicine such as dentistry, orthopedics, and surgery.
In addition to the above-mentioned industrial sectors, the use of modified starch in foundry, ceramics, household chemicals, industrial wastewater treatment and other industries is also increasing.
According to experts, compared with corn modified starch, cassava modified starch has many unique performance advantages. In some applications, corn modified starch is difficult to replace cassava modified starch. The United States, the European Union, and Japan, which use corn and potatoes as raw materials to produce modified starch, still have to build cassava modified starch plants in countries such as Thailand, Indonesia, and Brazil that produce cassava and produce tapioca modified starch for domestic consumption. One problem.
