Zearalenone contaminates food and poses a threat to human health. It is vital to develop cost-effective and environmentally-friendly adsorbents for its removal. By screening Sporobolomyces pararoseus (SZ4) and modified yam starch (adsorption capacity (q) of 1.33 and 0.94 mg/g, respectively), this study prepared a novel composite aerogel adsorbent (P-YSA@SZ4). The compressive strength of P-YSA@SZ4 was 1.35-fold higher than unloaded yeast. It contained several functional groups and three-dimensional interconnected channels, achieving a 0° contact angle within 0.18 s, thereby demonstrating excellent water-absorbent properties. With a q of 2.96 mg/g at 308 K, the adsorption process of P-YSA@SZ4 was spontaneous, endothermic, and matched pseudo-second-order and Langmuir models. The composite adsorbed zearalenone via electrostatic attraction and hydrogen bonding, maintaining a q of 2.24 mg/g after five cycles. P-YSA@SZ4 was found to remove zearalenone effectively under various conditions and could be applied to corn silk tea, indicating its great potential as an adsorbent material.
玉米赤霉烯酮污染食品并对人类健康构成威胁。开发具有成本效益且环保的吸附剂以去除它至关重要。通过筛选玫瑰掷孢酵母（SZ4）和改性山药淀粉（吸附容量（q）分别为1.33和0.94 mg/g），本研究制备了一种新型复合气凝胶吸附剂（P-YSA@SZ4）。P-YSA@SZ4的抗压强度比未负载酵母高1.35倍。它含有多个官能团和三维互连通道，在0.18 s内实现了0°接触角，从而展现出优异的吸水性能。在308 K下q为2.96 mg/g时，P-YSA@SZ4的吸附过程是自发的、吸热的，并且符合准二级动力学和朗缪尔模型。该复合材料通过静电引力和氢键吸附玉米赤霉烯酮，五个循环后q保持在2.24 mg/g。发现P-YSA@SZ4在各种条件下都能有效去除玉米赤霉烯酮，并且可应用于玉米须茶，表明其作为吸附材料具有巨大潜力。
