摘要: 为了延长油茶籽的加工期限,将含水量为6%、13%的油茶籽分别贮藏在25℃、室温、4℃,相对湿度(RH)50%~65%条件下,观察贮藏期间品质及生理生化变化。结果表明:所有实验贮藏方法,油茶籽贮藏90d后均出现一定程度的劣变现象,贮藏品质下降。对不同处理贮藏效果的综合评价,最好的贮藏条件为温度4℃、油茶籽含水量6%,能明显抑制呼吸强度和脂肪酶活性,保持较高蛋白质、脂肪、糖等内含物质的含量,阻止油茶籽品质的劣变;其次为温度4℃、含水量13%,最差的为温度25℃、含水量13%。低温和低水分含量可有效提高油茶籽的贮藏品质。

Abstract: In order to extend the storage period of Camellia oleifera seeds, we observed the quality as well as physiological and biochemical changes of Camellia oleifera seeds with moisture content of 6% and 13% during storage at three temperatures, 25 ℃, room temperature and 4 ℃, respectively and a relative humidity kept between 50% and 65%. The result shows that quality deterioration was observed for Camellia oleifera seeds as the storage period was prolonged up to 90 days. A comprehensive assessment of the effects of different storage conditions indicated that the best storage condition was 4 ℃ and 6% moisture content, significantly inhibiting the respiration intensity and lipase activity, maintaining a high content of protein, fat and sugar and preventing Camellia oleifera seeds from deteriorating. The next best was 4 ℃ and 13% moisture content. The worst results were observed for Camellia oleifera seeds with a moisture content of 13% stored at 25 ℃. Base on these results, we conclude that low temperature storage and low moisture content can effectively improve the quality of Camellia oleifera seeds.
