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B_1、B_2、G_1、G_2。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。
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 was4%-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.
