摘要
研究花生油开封后,在不同条件下49 d每间隔7 d按照标准方法测定酸价、过氧化值、苯并(a)芘、黄曲霉毒素B_(1)、铅、砷各项质量指标。结果表明:不同保存条件下,随着时间的增加,酸价、过氧化值、苯并(a)芘、黄曲霉毒素B_(1)均呈增加的趋势,在40℃和光照条件增加较快,避光、冷藏和常温条件下各项质量指标增加相对缓慢;铅、砷基本无变化。花生油要注意开封后的保存条件和质量变化。
After the peanut oil was opened,it was stored for 49 days under different conditions,the acid value,peroxide value,benzo(a)pyrene,aflatoxins B_(1),lead and arsenic were measured at 7-day intervals.The results showed that under different preservation conditions,the acid value,peroxide value,benzo(a)pyrene and aflatox-ins B_(1) all increased with time,and at 40℃and illumination conditions increased rapidly,under the condition of avoiding light,cold storage and normal temperature,the quality indexes increased relatively slowly.Lead and ar-senic basically did not change.Preservation conditions and quality changes of peanut oil should be noted after unsealing.
