Corn is one of the main grain crops in our country,which production is the second among the grains of the world.It accounts for more than one-fifth of all the grains.The safety storage of corn plays an important role in the industry development.In our study,two storage method were applied to help it to spend the summer.That is the conventional storage and temperatureconditioning storage in summer.During our storage period,the storage temperature,water contents,free fatty acid value,color,smell,and food quality and taste scores were tested and the cost of the corn under two storage conditions are also analyzed.A comprehensive analysis of all these aspects to show which corn storage is safer,more economical and more effective.The following conclusions:In the summer,the 13 th warehouse with air conditioning storage,which the surface temperature of corn grain is about 5 lower than that of the 14 th and 22 th whose corn under ?general storage,and the average grain temperature is about 4 lower.?In the summer,the 13 th warehouse with air conditioning,whose storage temperature maintained about 26?,the 14 th and 22 the general storage warehouse?s temperature at about 30 ?.During the air conditioning temperature control,the 13 th warehouse with air conditioning storage,whose water content is no change,but the 14 th and 22 th general storage warehouse?s water contents are obviously under the influence of wet outside.At the beginning of September than at the end of September,the 14 th and 22 th general storage warehouse?s water contents have risen by 0.2%.At the end of September,the 14 th storage warehouse?s water content down 0.2%,the 22 th storage warehouse?s water content down 0.1%.From the corn color,smell,the color of the experimental warehouse is more bright,the smell is more normal,and abnormal,but the general storage warehouse?s corn has a slight moldy smell.The 13 th warehouse?s food quality and value of the goods is higher thangeneral storage warehouse?s in the period of air conditioning,and fatty acid value is lower 1mg/100 g than the 14 th and 22 th general storage warehouse?s from June to September.The 13 th warehouse with air conditioning whose taste scores 3 points higher than the general storage warehouse?s.From the last benefit,The 13 th warehouse with air conditioning whose benefit is higher than the 14 th and 22 th general storage warehouse?s 0.01 yuan per kilogram.From the end of the result,the 13 th warehouse with air conditioning storage,which income is highertwentytwo thousand and three hundred yuan than the 14 th general storage warehouse?s,higher eighteen thousand and nine hundred yuan than the 22 th general storage warehouse?s.So the warehouse with air conditioning storage whose final benefit is higher than the warehouse with general storage.The fourth ecological storage area in China,The corn storage which use air condition can control temperature,water control and delay the quality of corn.The air-conditioning technology is safe,economic and applicable,which is worth to be promoted.
