Development of corn oil industry in the world and China

Introduction: Xinhua news agency, Shanghai, April 27 (reporter Feng Yuan) at the "2002 International Symposium on essential fatty acids and human nutrition and health", China International Engineering Consulting Company, on behalf of Huang Shikeng, introduced the development of corn oil industry in the world and China In 1990, the world's corn oil output was 1.49 million tons, reaching 2.05 million tons in 1999, with an average annual growth rate of 3.6% The United States is a major producer of corn oil, with an output of 750000 tons in 1990 and 1106000 tons in 1999, accounting for 54% of the world's corn oil production, with an average annual growth rate of 4.4% Europe's output in 1990 was 173000 tons, reaching 196000 tons in 1999, with an average annual growth rate of 1.4% In recent 10 years, the output of corn oil in Japan has remained at about 100000 tons MXP corn oil in the United States ranks the second in domestic consumption of edible oil, second only to soybean oil It was 525000 tons in 1990, 620000 tons in 1999, with an average annual growth rate of 2% In 1990, the consumption in Europe was 211000 tons, reaching 52000 tons in 1999, with an average annual growth rate of 3.5% In recent 10 years, the consumption of corn oil in Japan has remained stable at about 100000 tons, with a basic balance between supply and demand In addition to meeting domestic demand, American corn oil also has a large number of exports In 1990, the export volume was 226000 tons, reaching 486000 tons in 1999, an increase of 1.2 times, an average annual increase of 8.8%, an average annual increase of 29000 tons, and the export rate of products in 1999 reached 43.9% The oil content of MXP common corn is only about 4%, and 85% of the oil is concentrated in the corn seed embryo Therefore, corn oil is mainly produced by the technology of embryo extraction, which is often the by-product of comprehensive processing of corn, part of which comes from the by-product of processing corn starch sugar, part of which comes from the by-product of fuel ethanol production In 1998, nearly 50 million tons of corn were used for deep processing in the United States, accounting for 1 / 4 of the consumption of 200 million tons, most of which were extracted by embryo for oil extraction The consumption of corn in the United States is 1.7 times of that in China, while the output of corn oil is 55 times of that in China MXP corn oil is basically edible refined corn oil in the world, but most corn oil in China is crude crude oil, which is used to produce soap In 1999 and 2000, China's corn oil (crude oil) output was similar, about 102000 tons, of which more than 70% was used for soap production and less than 30% was processed into edible refined corn oil The output of refined edible corn oil in China was 20000 tons in 1999 and 21000 tons in 2000, accounting for about 0.96% of the total output of corn oil in the world In 2000, the total consumption of edible oil in China was 11.33 million tons, while the output of edible corn oil only accounted for 0.17% of the total consumption of edible oil MXP currently, China's corn consumption is about 120 million tons, ranking the second in the world, second only to the United States, while China's corn used for deep processing is only about 10 million tons, accounting for 8% of the consumption, less than 5 million tons of oil extracted from embryos, and the average proportion of oil extracted from embryos is less than 4% of the total corn consumption MXP is closely related to China's corn consumption structure At present, China's corn is mainly used for feed and rations, of which 70-80 million tons are used as feed, accounting for 60-70%, 17 million tons are used as rations, accounting for 14%, while only 8% are used for industrial deep processing MXp
