不同贮藏条件下油茶籽品质及生理活性

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。

Quality and Physiological Changes of Camellia oleifera Seed under Different Storage Conditions

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.
