Biotechnological richness of the northeastern semi-arid region: antioxidant activity of casein hydrolysates from Moxotó goat milk (Capra hircus Linnaeus, 1758) obtained by papain action

Effect of digestive enzymes on the bioactive properties of goat milk protein hydrolysates

“…The high enzyme-substrate ratio employed in this work allowed a high DH level to be reached in a relatively short reaction time. Similar final DH values were obtained in the hydrolysis of goat caseins by papain when employing lower E:S ratios (0.5e1.5%) but longer reactions times (5 h) (Bezerra et al, 2013). Fig.…”

“…Likewise, Li et al (2013) identified antioxidant peptides in goat milk casein hydrolysates produced by a combination of neutral and alkaline proteases. Bezerra et al (2013) also reported antioxidant activity for the permeate of goat casein hydrolysates produced by using papain.…”

Production optimization and characterization of immunomodulatory peptides obtained from fermented goat placenta

“…Immunoregulatory peptides in the range of 3KDa-10 KDa extracted from goat placenta could enhance humoral immunity function and recover the ability of humoral immunity in mice with immunodeficiency (Liaoqiong et al, 2005). Bezerra et al (2013) demonstrated that the activity level was higher in permeate peptides (<3KDa) than in retentate peptides (>3KDa). These authors used ultrafiltration technique to evaluate the influence of peptides molar mass molecular weight on biological activities.…”

Application of the Plackett-Burman design to determine the main factors affecting the anti-oxidative activity of goat's milk casein hydrolyzed by Alcalase and papain [pdf]

“…www.food.actapol.net/ 2017). This was because the optimum range of Alcalase was probably between 7 and 9 and the optimum pH value of papain was between 6 and 8 (Bezerra et al, 2013). When pH = 7.5, the substrate bonded strongly with the two proteases, at the same time, the optimum pH conditions of the two proteases was not exceeded.…”
