Study On The Law Of Quality Changes Tall Cottage Store Bulk Rice In Luxi Area

In order to study the change about quality in the bulk grain storage of LuXi area,the experiment explore new library of liaocheng district solid warehouse to hide rice during the period of one year storage temperature and moisture content,find the changes of roughness,the whole white rice rate,fatty acid value,germination rate,viscosity,taste evaluation,etc.During this test on a regular basis for storage of rice quality,quality indicators determined,and then user software to analyze the measured data,analysis,the change rule of every index and its differences and the correlation among the indexes.To reduce the loss of grain storage and delay rice to provide theoretical support of quality deterioration,further improve the level of enterprise safety storage and warehousing management,so as to realize scientific and rational storage of rice.The main results as follows:In LuXi area,warehousing,barn type,safekeeping measures the same quality,good in sealing under the condition of antibacterial activity during the bulk grain storage,with the extension of the storage time and the retrogradation degree deepens,integrated rice moisture content,the roughness,the whole polished rice rate,fatty acid values,germination rate,viscosity,and changes of the taste evaluation value during storage,the barn the stored grain moisture content,taste evaluation value,germination rate,the roughness,the whole white rice rate,viscosity,etc are declining,fatty acid values rising trend.Including water content,the roughness and taste evaluation value of relatively slow decline,the germination rate fell by 10% on average,viscosity with the increase of storage time on average from 7.6 pa.s dropped to 4.8 pa.s,have significantly lower,and fatty acid value of the overall increase is higher,not one of them equipped with refrigeration and temperature control equipment barn samples increased rate of fatty acid value is higher than the refrigeration temperature control device is equipped with barns.Through research on the test,find the rice in luxi region climate conditions,to store a year cycle and the quality change rule,on this basis to achieve more reasonable scientific grain storage.
