摘要
为探索茶籽象为害对油茶果产量及茶油品质的影响,对健康茶果和受害茶果平均籽重、茶籽出油率、所提炼茶油的酸值、过氧化值、苯并芘和黄曲霉毒素B1含量等一系列指标进行了对比测定。结果表明:健康茶籽的平均重量7.89g显著高于受害茶籽6.58g(P<0.001);受害茶籽出油率显著低于健康茶籽,仅为后者的71.15%(P<0.05);受害果的茶油中酸值平均含量为17.79mg/g,过氧化值平均含量0.66g/100g,两个指标都极显著高于健康的茶油,且显著高于食用油国家标准;受害果茶油中苯并芘含量明显增高,但与健康果茶油差异不显著;受害果茶油和健康果茶油中均未检出黄曲霉毒素。本研究明确了茶籽象为害对油茶产量及茶油质量的影响,为茶籽象的防治及茶油加工提供了参考。
To determine the effect of the damage caused by Curculio chinensis on fruit yield of Camellia chinensis and nutritional value of C.chinensis seed oil,6 indexes,including the weight of seed,oil yielding rate,acid value,peroxide value,benzopyrene and aflatoxin B1,were tested.The results showed that the average weight of the healthy seeds was 7.89 g,significantly higher than that of the damaged ones（6.58 g,P〈0.001）.The oil yielding rate of damaged seeds,which was only 71.15% of that of the healthy seeds,decreased significantly（P〈0.05）.The mean acid value and peroxide value of camellia oil extracted from damaged seeds（17.79 mg/g and 0.66 g/100 g,respectively）were significantly higher than that of the camellia oil extracted from healthy seeds and above national standards.Benzopyrene content in camellia oil increased after damage,but the difference was not significant.Carcinogenic aflatoxin was not detected in camellia oil extracted from damaged seeds or healthy seeds.This study demonstrated the effects of the damage caused by C.chinensis on camellia production and oil quality,and provided the basis for the control of C.chinensis and camellia oil processing.
