中文摘要:
      为研究霉变油茶籽对压榨油茶籽油的影响，选择在新鲜油茶籽中，按不同比例添加严重霉变的油茶籽，分别混合粉碎后，120?℃干燥至水分含量为4%~7%，然后冷却到50?℃，分别投入榨油机进行压榨，称取所得油茶籽油，计算出油率，并将油茶籽油过滤，检测其透明度、气味、滋味、酸价、过氧化值、黄曲霉毒素等指标。结果表明：霉变油茶籽对油茶籽出油率和油茶籽油气滋味、酸价影响较大，但没有检测出黄曲霉毒素 B1、B2、G1、G2。为了确保油脂品质，消除潜在风险，在榨油前应进行霉变油茶籽的筛选。
英文摘要:
      In order to study the effect of mildew oil-tea camellia seeds on pressed oil-tea camellia seed oil, severe mildew oil-tea camellia seeds were added in fresh oil-tea camellia seeds with different proportions. Then they were mixed and crushed into particles, dried at 120?℃ till the moisture content was 4%-7%, cooled to 50?℃, and pressed for oil. The oil yield was calculated, and the oil-tea camellia seed oil was filtered to detect its transparency, odor, taste, acid value, peroxide value, aflatoxin and other indicators. The results showed that the mildew oil-tea camellia seeds had a great influence on the oil yield, odor and taste and acid value of oil-tea camellia seed oil, but no aflatoxin B1, aflatoxin B2, aflatoxin G1, and aflatoxin G2 were detected. To ensure the oil quality and eliminate potential risk, mildew oil-tea camellia seeds should be screened out.
