Abstract

Graphical abstract: Highlights: The biowaste eggshells were firstly modified into deoxynivalenol (DON) adsorbents. The novel adsorbent can adsorb 53.0% DON in the acidity-adjusted buffer solution. The novel adsorbent can alleviate DON-induced damage of intestinal cells. Abstract: Deoxynivalenol (DON) is widely contaminated in foods and feeds, which greatly threatens human and animal health. Due to its stable physicochemical properties, DON can be hardly eliminated by heating or ultraviolet radiation. In the present study, the biowaste eggshells were firstly modified into effective DON adsorbents, which are ATPS (triethoxysilane) + TEOS (aminopropyl triethoxysilane) modified 500 °C/700 °C-calcined eggshell powders under acetic/propionic acid-catalyzation (500-CSAE, 500-CSPE, 700-CSAE, 700-CSPE). The adsorption rates of DON on the raw eggshell powder, 500-CSAE, 500-CSPE, 700-CSAE, and 700-CSPE in acidity-adjusted buffer solution were 14.6%, 53.0%, 47.8%, 29.9%, and 31.2%, respectively. Characteristic analysis implied that the mesopore structures and enriched Si-OH groups in the modified eggshell powders are involved in DON adsorption. Besides, 500-CSAE, 500-CSPE, and 700-CSPE were verified to numerically alleviate the viability loss of IPEC-J2 cells caused by DON. In conclusion, the novel modified eggshell powders exhibit great application prospects for DON control in foods and feeds.
