摘要
本文对海南地区 2020-2023 年稻谷脂肪酸值进行调查.结果表明,海南地区2020-2023 年新粮入库稻谷中脂肪酸值集中在 14.0～18.0 mg/100 g,其中有2份样品不符合琼粮粮[2020]70号文件要求;储备粮的脂肪酸值为 15.2～42.6 mg/100 g,平均值为 27.6 mg/100 g,其中轻度不宜存样品 42 份,占比为19%;重度不宜存样品13份,占比为6%.定安县的不宜存样品数最高,为10个,占比高达50.0%.澄迈县、东方市、陵水县和琼海市的样品均为宜存,其不宜存样品占比均为 0%.对于采集的早籼稻谷与晚籼稻谷,在储备粮重度不宜存样品中,晚籼稻谷的占比相对于早籼稻谷的占比大.
Abstract
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.
