* Values (mean ± SD) illustrated in this table are in triplicates (n = 3). For each parameter, different superscript letters indicated the significant differences among FBPC protein hydrolysates viz., slurry with adjusted pH and temperature treatment without Alcalase (HA₀), 5 min hydrolysis with Alcalase (HA₅), 10 min hydrolysis with Alcalase (HA₁₀), 15 min hydrolysis with Alcalase (HA₁₅), and 30 min hydrolysis with Alcalase (HA₃₀), and native FBPC protein (EC), FBPC protein hydrolysates viz., slurry with adjusted pH and temperature treatment without Alcalase after UHT treatment (EA₀), 5 min hydrolysis with Alcalase after UHT treatment (EA₅), 10 min hydrolysis with Alcalase after UHT treatment (EA₁₀), 15 min hydrolysis with Alcalase after UHT treatment (EA₁₅), and 30 min hydrolysis with Alcalase after UHT treatment (EA₃₀) within a column at 95% confidence level (p < 0.05).
