The Native Starch Industry of Thailand plays an important role in the economy of Thailand. Native starch is extracted from the root of the tapioca plant, which has the ability to grow in dry weather and low-nutrient soils where other crops do not grow well. Tapioca roots can be stored in the ground for up to 24 months, and some species for up to 36 months, thus harvest may be extended until market conditions are favorable or native starch production capacity is available. The total area of tapioca plantations in Thailand during 2007 was about 7.48 million Rai (1 Rai = 1600 square meters), allowing the production of about 26.41 million tons of native starch and generating income of about 29,581 million Baht. The largest proportion of tapioca plantations in Thailand is in the Northeast region. The top 5 provinces with highest plantation areas are Nakhon Ratchasima, Kampangpetch, Chaiyaphum, Srakaew and Chachoengsao.〔Office of Agricultural Economics, Ministry of Agriculture and Cooperatives, 2007〕 ==Types of production== The Tapioca agricultural industry in Thailand has three types of production as follows: * Native starch production (dry powder, slurry and cake) * Modified starch production * Starch derivatives production (glucose, fructose, dextrose, maltose, sorbitol, etc.) According to the Information and Communication Technology Bureau, Department of Industrial Works, there are 93 native starch factories as of 2007. Northeastern Thailand has the highest number of native starch factories (46%) followed by the East region (31%), Central region (15%) and North region (8%) respectively. Native starch factories are typically located in the same areas as tapioca plantations. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Native starch industry of Thailand」の詳細全文を読む スポンサード リンク
