Characterization, stability, and in vivo effects in Caenorhabditis elegans of microencapsulated protein hydrolysates from stripped weakfish (Cynoscion guatucupa) industrial byproducts

•Maltodextrin was used to microencapsulate stripped weakfish protein hydrolysate.•Microencapsulate protein hydrolysates were evaluated in vitro and in vivo.•Microencapsulation decreased the hygroscopicity of protein hydrolysates.•Microencapsulated hydrolysates showed in vitro antioxidant activity.•Protein hydrolysate or microencapsulated protect in vivo from oxidative stress.
