Development status and future development trend of world cassava starch industry

The country with the largest cassava production in the world is Nigeria, with more than 33 million tons. Followed by Congo (DRC), Brazil, Indonesia and Thailand. In Africa and Latin America, cassava is mainly used for food and feed consumption, and there are dozens of cassava foods in Brazil. In China and Thailand, cassava is mainly used to process dry chips, granules, starch and its deep processed products.

The main products of cassava entering the international market are dry chips and starch. In recent years, the world's imports of cassava chips and starch are about 6 million tons, of which the EU imports about 3.5 million tons, Japan imports about 1.2 million tons, South Korea imports about 600,000 tons, and China imports about 300,000 tons. Thailand is a major exporter of cassava chips and cassava starch. In recent years, its export volume is about 4.8 million tons, accounting for 80% of the world's total exports. Since the 1990s, due to the rapid development of the feed industry and the starch industry, the demand for cassava in the international market has increased year by year. According to industry estimates, the world's cassava output will reach 271 million tons by 2020, and the market for cassava production and processing is considerable.

Development status and future development trend of world cassava starch industry

1. Development status

In recent years, the total output of cassava starch in the world is 370-420 million tons, including 150-180 million tons in Thailand, 80-100 million tons in Vietnam, 500,000 tons in Indonesia and more than 300,000 tons in Brazil. Cassava starch industry in Thailand and Vietnam is mainly exported, and the main exporter of cassava starch in Southeast Asia is China.

2. Development trend of cassava starch industry production technology

① Cassava starch processing to large-scale development

② Cassava starch processing technology has achieved automatic control of the production process

③ Extensively promote energy-saving technologies and equipment with low energy consumption and high efficiency

④ Cassava starch industry products are developed in the direction of serialization, which can further processed into modified starch, syrup, alcohol, etc., to get more widely usage.

II Cassava starch industry for modified starch processing

1. Development status

In the past decade, the world's production of modified starch has grown rapidly. The current annual output has reached 7 million tons, including: about 3.5 million tons in the United States, with the world's largest modified starch enterprise; more than 2 million tons in the EU; 300,000 tons in Japan, Thailand 450,000 tons; China 400,000 tons. There are more than 30 application fields of modified starch, among which the paper industry, textiles, food and other industrial sectors use the largest amount.

As a raw material of modified starch, cassava starch has the characteristics of low price, low non-starch impurity content, high viscosity, low gelatinization temperature, stable and transparent paste liquid, good film formation and strong permeability, so the price and quality of cassava modified starch both sides are high competitive.

2. Development trend of production technology

① New processing technology is continuously developed

In addition to humidity, dry method, and pre-gelatinization, extrusion processing technology of modified starch has been developed, and infrared irradiation processing technology and microwave irradiation processing technology are being researched and developed.

② Varieties develop in the direction of diversification, serialization and specialization

Such as paper-making modified starch series, and even coating series, surface sizing series. One example is that the same variety produced by a foreign modified starch company has a variety of grades, and the product has a strong specificity. Even the same variety, different substituents, different degrees of substitution, different viscosities, different pH values, have different application effects, and are suitable for different application purposes and conditions.

③ Constantly open up new application areas

Cassava starch processing plant overview

There are more than 30 application fields of modified starch in the world. In addition to the industrial sectors such as paper, textile, food, medicine, aquatic feed, building materials, casting, etc., it is still in the industrial sectors of petroleum, mining, coal, ceramics, daily necessities, cosmetics, etc. And the expansion of the agriculture and forestry sectors. Gradually develop varieties of modified starch that meet the actual needs, such as developing modified starch suitable for grass fiber and recycled fiber papermaking. Develop oils suitable for deep wells (greater than 4,500 m), high temperature resistant (150-180 ° C or higher), salt-tolerant (NaCl to saturated), calcium or magnesium-resistant tackifiers, fluid loss additives, etc. Modified starch products for drilling. Considering the trend of increasing hypertension, hyperlipidemia and diabetes in the world, the development of edible modified starch should cater to the needs of this era, develop fat substitutes and sugar metabolism substitutes that have both energy and nutrition without affecting blood sugar. There are also superabsorbent resins, starch plastics, and the like.

The cassava starch industry is a large product group that includes cassava planting, cassava starch processing and alcohol deep processing. This product group has as many as 3,000 products, which involve various fields of life. The real market and potential market are huge and have broad development prospects. At present, some multinational companies with starch and its derivatives as the main products in the world have annual sales of more than billions of dollars.
