Investigation on Rice Fatty Acid Value in Hainan 2020 to 2023
The fatty acid value of rice in Hainan from 2020 to 2023 was investigated.The results showed that the fatty acid value of new grain imported into storage rice in Hainan from 2020 to 2023 ranged from 14.0 mg/100 g to 18.0 mg/100 g,among which 2 samples did not meet the requirements of Hainan Provincial Grain and Material Reserves Bureau Document No.70(2020).The fatty acid values of the reserve grains ranged from 15.2 mg/100 g to 42.6 mg/100 g,and the average value was 27.6 mg/100 g,among which 42 samples were mildly unsuitable for storage,accounting for 19%.There were 13 severe samples,accounting for 6%.The number of unsuitable samples in Ding'an county was the highest,10 samples,accounting for 50.0%.Samples from Chengmai county,Dongfang city,Lingshui county and Qionghai city were all suitable for storage,and the proportion of samples not suitable for storage was 0%.For the collected early indica rice and late indica rice,the proportion of late indica rice in the samples that should not be stored in the heavy grain reserve is larger than that of early indica rice.
