This study was aimed at producing nanocellulose from sugarcane bagasse and durian rind residues for applications to determine adsorption capacity against mycotoxin in poultry diets. Durian rind-derived nanocellulose exhibited finer fiber (12–21 nm diameter and 197–350 nm length) and higher yield (42.1%) than bagasse-derived nanocellulose (18–36 nm diameter and 82–169 nm length), with FTIR confirming purer cellulose I/II structures. The in vitro test adsorption capacity against ochratoxin (OTA) was determined at an incubation time of 180 min to establish working conditions. It was found that the working conditions of bagasse-derived nanocellulose and durian rind-derived nanocellulose were 33 mg/mL and 36.5 mg/mL, respectively. Subsequently, using these working conditions, adsorption capacity was determined via an in vitro digestibility test. Bagasse-derived nanocellulose exhibited an adsorption capacity against OTA of 35.59%, while durian rind-derived nanocellulose achieved an OTA adsorption rate of 39.53% at a contact time of 3 h. Naturally contaminated poultry feeds collected from nine farms in Chiang Mai, Thailand, indicated that both types of nanocelluloses achieved minimum–maximum OTA adsorption rates of 42–43%, aflatoxin B1 (AFB1) at 29–30%, and fumonisin B1 (FB1) at 21–23% across the nine farms’ mean values. These findings suggest that nanocellulose derived from sugarcane bagasse and durian rind has potential as a sustainable biosorbent for improving mycotoxin management in poultry production.
