等离子体处理对花生油品质的影响
|
摘要
研究采用低温射频等离子体技术处理花生油,处于激发态的等离子体可能会引起油脂的理化性质发生改变,因此以花生油中的酸价、碘价、过氧化值、维生素E、氧化稳定性和反式脂肪酸含量等作为检测指标,来评估低温射频等离子体去除黄曲霉毒素过程中对其对花生油品质的影响。实验结果表明,经100 W、200 W和300 W的等离子体处理花生油10 min后,花生油的酸价从0.87mg KOH/g分别减少到0.28、0.25和0.26,差异显著(p<0.05)。碘价在10 min范围内的变化幅度不大,差异不显著(p>0.05)。在实验所处理的范围内,花生油的过氧化值均未超出6 mmol/kg。通过高效液相色谱分析,等离子体对花生油中的维生素E和反式脂肪酸含量的影响较小。说明低温射频等离子体技术降解花生油中的AFB1的方法不仅安全、有效,而且也不会影响花生油的品质。
Peanut oil was treated with low-temperature radio frequency plasma, and the plasma in an excited state may cause changes in the physicochemical properties of oil. Acidity, iodine content, peroxide content, vitamin E(VE), oxidation stability, and the concentration of trans-fatty acids of peanut oil were used as indicators to assess the influence of the aflatoxin removal process using low-temperature radio frequency plasma on quality of peanut oil. The results showed that after the peanut oil samples were treated with plasma at 100, 200 or 300 W for 10 min, the acidity values were reduced to 0.28, 0.25 and 0.26 mg KOH/g, respectively, and there were significant differences(p<0.05). The iodine value did not change substantially within 10 min, and the differences were not significant(p>0.05). Within the range of the experimental treatment, peroxide content of peanut oil was always below 6 mmol/kg. High-performance liquid chromatography(HPLC) analysis indicated that VE and trans-fatty acid contents were affected by the plasma treatment only slightly. The use of low-temperature radio frequency plasma to remove aflatoxin B1(AFB1) is not only safe and effective but also maintains the quality of peanut oil.
