The effects of peptides derived from β-lactoglobulin and α-lactalbumin on metabolic syndrome were studied. α-lactalbumin and β-lactoglobulin were hydrolyzed with trypsin, alcalase, flavourzyme, or a combination of alcalase and flavourzyme and fractionated. Angiotensin coverting enzyme inhibition of the < 1 kDa fraction of alcalase hydrolyzed β-lactoglobulin was 95 %. Antioxidant activity of the < 1 kDa fraction of β-lactoglobulin hydrolyzed with a combination of alcalase and flavourzyme was 18 %. Stimulated adipocytes incubated with the < 1 kDa fraction of β-lactoglobulin hydrolyzed with either trypsin or alcalase produced 30 pg/mL of interleukin 6. Adiponectin and glucose transporter type 4 secretions increased 1.1 and 0.86 fold respectively during incubation with the < 1 kDa fraction of β-lactoglobulin hydrolyzed with a combination of alcalase and flavourzyme. Results indicate that β-lactoglobulin peptides formed with alcalase and a combination of alcalase and flavourzyme influence markers associated with metabolic syndrome and may be useful as functional foods or nutraceuticals.
