As one of the important raw and auxiliary materials in industry, modified starch can be widely used in papermaking, food, textile, construction, medicine and other industries. Manufacturers should actively develop new products and expand the application fields of modified starch.

1. Modified starch for food should be based on functionality, diversity and convenience. For grain processing, it is necessary to develop new varieties, focusing on the development of corn series products, potato starch, modified starch and derivative products; development of convenience food, nutritional and health food, and emulsifying and thickening quality improvers. Therefore, the modified starch for food can develop functional modified starch, modified starch for convenience food and alkenyl succinate starch with tight domestic supply. As a food additive, modified starch should take into account the increasing trend of patients with high blood pressure and hyperlipidemia in my country, and develop fat substitutes and sugar substitutes that have both energy and nutritional value and do not affect blood sugar, so as to meet the incidence of diabetes. Demand is rising year by year. At present, fat substitutes based on starch can be applied to almost all foods that need to be added with fat; the developed anti-digestive starch has low water holding capacity, fine particles, refreshing flavor, and microcrystalline structure smaller than ordinary dietary fiber, and can also be used as a functional ingredient Used in a variety of foods.

2. The development speed of modified starch, which can completely replace chemical pulp PVA, also needs to be accelerated. The modified starch used in textile sizing is mainly acid-thinned starch, oxidized starch, urea starch, phosphate starch, etc., and a small amount of acetate starch and compound modified starch. These varieties are difficult to replace the chemical size PVA 100%, especially in the sizing of high-end yarn products. Due to its non-degradability, people gradually use less or even no PVA in textile pulp. There are similar products on the market in foreign countries. It is believed that with the efforts of domestic modified starch industry personnel, this product can be developed completely.

3. Development of new surface coating agents and sizing agents in the paper industry: Lishi meets the needs of the product structure of the national paper industry. Modified starch is an important papermaking chemical. The amount of modified starch used in papermaking in my country is 1/3 of the total amount of modified starch in the country, but the variety is single and the level is low. At present, the product structure of the national paper industry is developing towards the direction of high-grade newsprint, book printing paper, information paper, office paper and other medium and high-end household paper, which requires the development of new surface coating agents and sizing agents to adapt to the needs of the paper industry.

4. Starch-based water-absorbing agent is widely used. Water-absorbing agents can be used in agriculture, forestry and gardening, medicine and hygiene, textiles, papermaking, oil drilling, construction, wastewater treatment, and food processing. At present, some industries rely on a large number of imported expensive water-absorbent products to meet market demand, and most of the imported products are polymer synthetic products. Today, when oil is facing depletion and environmental protection is getting more and more attention, the market of this kind of products is facing a crisis, and the renewable natural starch resources are used to undergo graft copolymerization with acrylic acid or acrylonitrile through chemical treatment. It is the development direction of this product to prepare a biodegradable water-absorbing agent by adding hydrophilic macromolecules to replace the water-absorbing agent synthesized from petroleum refining.
