摘要:以玉米油中玉米赤霉烯酮(ZEN)脱除率为主要考察指标,以玉米油脱色效果为次要考
察指标,研究吸附剂种类和吸附剂用量对玉米油中ZEN脱除效果和脱色效果的影响。结果表明
WY1活性炭対玉米油中ZEN的脱除效果优于其他吸附剂。当吸附剂用量为油重1%时,活性白土
凹凸棒石、WY1活性炭、WY2活性炭、普通活性炭及 NORIT活性炭对玉米毛油中ZEN的脱除率
分别为5.57%、10.73%、38.50%、11.10%、14.45%和17.35%,ZEN含量由8026.67g/kg分别降
至7579.28、7165.38、4936.46、7135.34、6867.12、6634.27gkg。WY1活性炭用量2%时,ZEN
脱除率达到48.25%,ZEN含量降至4153.77g/kg,明显高于欧盟要求400ug/kg的限量。因此,
对于ZEN含量很高的玉米毛油,必须结合优化的藏炼脱酸及水蒸气蒸馏脱臭的精炼过程才能对
ZEN进行系统和高效的脱除,但解決问题的根本是要严格控制待精炼玉米毛油的ZEN含量,即减
少和控制玉米胚中ZEN含量,提高玉米胚质量。

Abstract: With rcmoval ratc of zcaralcnonc(ZEN )in maize oil as main index, bleaching cffect
as secondary index, the effect of removal of ZEN from maize oil by different absorbent types and
absorbent dosage were studied, The results showed that the effect of activated carbon WY I on removal
of ZEN was better than other adsorbents. With the usc of 1% activated clay, attapulgite, activated
carbon WYI, activated carbon WY2, gcncral activated carbon and activated carbon NORIT, thc ZEN
contents of crude maize oil were dccrcascd from 8026.67 ug/kg to 7579.28, 7 165.38, 4. 46
7 135.34, 6 632.26 and 6 634.27 ug/kg, respectively, which were significantly higher than the EU
requirements that the limit of ZEN content in edible corn oil was set at 400 ug/kg And the removal
rates were 5.57%, 10.73%, 38.50%, 11.10%, 17.37% and 17.35%, respectively. Therefore, the crude
maize oil with high conccntration of ZEN must bc refined with optimized alkali refining and steaming
deodorization. Then the ZEN was rcmovcd systmatically and cfticicntly But solving the root of the
problcm was to strictly control the ZEN contcnt of crude maize oil. In other words, it was to control th
ZEN content of corn germ strictly and improve the quality of corn germ
Key words: maize oil zearalenone: absorbent; removal effect
