The anti‐diabetic actions of a boarfish protein hydrolysate (BPH) were investigated in cultured cells and mice. A boarfish (Capros aper) muscle protein hydrolysate was generated using the enzymes Alcalase 2.4 L and Flavourzyme 500 L. Furthermore, the BPH was subjected to simulated gastrointestinal digestion (SGID). BPH and SGID samples (0.01–2.5 mg mL⁻¹) were tested in vitro for DPP‐IV inhibition and insulin and GLP‐1 secretory activity from BRIN‐BD11 and GLUTag cells, respectively. The BPH and SGID samples, caused a dose‐dependent increase (4.2 to 5.3‐fold, P < 0.001) in insulin secretion from BRIN‐BD11 cells and inhibited DPP‐IV activity (IC₅₀ 1.18 ± 0.04 and 1.21 ± 0.04 mg mL⁻¹), respectively. The SGID sample produced a 1.3‐fold (P < 0.01) increase in GLP‐1 secretion. An oral glucose tolerance test (OGTT) was conducted in healthy mice (n = 8), with or without BPH (50 mg/kg bodyweight …
