Preparation of zearalenone adsorbent, adsorbent and application thereof, and method for removing zearalenone in vegetable fat

The invention belongs to the field of food processing, and discloses preparation of a zearalenone adsorbent, the adsorbent and application thereof, and a method for removing zearalenone in vegetable fat. The preparation method comprises the following steps: crushing and screening crop straws to obtain crop straw powder; soaking the crop straw powder in a NaOH aqueous solution, carrying out solid-liquid separation to obtain a solid-phase substance, washing, filtering, drying, crushing and screening to obtain modified crop straw powder; the modified crop straw powder and Al2O3 are mixed and compounded, and the zearalenone adsorbent is obtained. The crop straw is rich in raw material source and low in price. The preparation method of the adsorbent is simple, less chemical reagent is used, and the adsorbent is environment-friendly. 本发明属于食品加工领域，公开了一种玉米赤霉烯酮吸附剂的制备和吸附剂及应用和脱除植物油脂中玉米赤霉烯酮方法。该制备方法包括如下步骤：对农作物秸秆进行粉碎和筛分，得到农作物秸秆粉末；将所述农作物秸秆粉末浸泡于NaOH水溶液中，固液分离得到固相物，经洗涤过滤、干燥、粉碎和筛分获得改性农作物秸秆粉末；将所述改性农作物秸秆粉末与Al2O3混合复配，得到所述玉米赤霉烯酮吸附剂。
