BACKGROUND: Bioactive peptides might be released from precursor proteins through enzymatic hydrolysis. These molecules could potentially employed in health and food products. In this investigation, ovine milk caseinate hydrolysates obtained with a novel microbial protease derived Bacillus sp. P7 were evaluated for antioxidant, antimicrobial, angiotensin I-converting enzyme (ACE)-inhibitory activities. RESULTS: Antioxidant activity measured by the...
Commercial nisin was encapsulated in nanovesicles (mean diameter 140 nm) prepared from partially purified soy lecithin. Nisin-loaded liposomes and unencapsulated (free) were initially tested BHI medium skim milk inoculated with Listeria monocytogenes incubated for 48 h at 30 degrees C. At such abuse temperature conditions, free showed better inhibitory than the liposomal counterparts. Subsequently, effect of or evaluated combination refrigeration (7 +/- 1 C) both whole (3.25% fat) (0% up to...
Water soluble extracts (WSE) of ewe's cheeses produced in Uruguay and Brazil were evaluated for their biological activities. Feta-type, Roquefort-type Pecorino-type from Brazil, Pecorino Sardo-type Cerrillano cheese samples Uruguay, analyzed. Antioxidant properties using distinct methods. Scavenging the cation radical 2,2′-azino-bis-(3-ethylbenzothiazoline)-6-sulfonic acid (ABTS) ranged 32 to 45% Feta-type 87% cheese. A similar trend was observed reducing power, where WSE showed highest...
Enzymatic proteolysis may be employed to release bioactive peptides, which have been investigated for potential benefits from both technological and human health perspectives. In this study, sheep cheese whey (SCW) was hydrolyzed with a protease preparation Bacillus sp. P7, the hydrolysates were evaluated antioxidant angiotensin I-converting enzyme (ACE)-inhibitory activities. Soluble protein free amino acids increased during hydrolysis of SCW up 4 h. Antioxidant activity hydrolysates, by...
Applications of keratinases demand efficient production and downstream processing. This work reports the production, purification partial characterization a keratinolytic protease from Serratia marcescens P3. The influence temperature, initial pH feather meal concentration on enzyme was investigated using response surface methodology. Maximal (12.5 U mL−1) observed at 18–30 °C, 10–24 g L−1 meal, values 6.5–8.5. recovered culture supernatants aqueous two-phase systems (ATPSs), higher yields...
