Antioxidant Peptides from Goat Milk Fermented by Lactobacillus casei L61: Preparation, Optimization, and Stability Evaluation in Simulated Gastrointestinal Fluid

Preparation and Characterization of Antioxidant Peptides from Fermented Goat Placenta

The goat placenta was fermented by Bacillus subtilis and the optimal fermentation parameters of strongest antioxidant capacity of peptides were obtained using response surface methodology (RSM). The effects of fermentation time, initial pH value and glucose content on the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging capacity of the goat peptides were well fitted to a quadric equation...

Optimization of Goat Milk with ACE Inhibitory Peptides Fermented by Lactobacillus bulgaricus LB6 Using Response Surface Methodology.

In the present study, the incubation conditions of goat milk fermented by Lactobacillus bulgaricus LB6 were optimized to increase the angiotensin converting enzyme (ACE, EC 3.4.15.1) inhibitory activity by Box-Behnken design of response surface methodology. Incubation temperature, whey powder, and calcium lactate had significant effects on ACE inhibition rate and viable counts of LB6 during inc...

Anticancer Effect of Goat Milk Fermented by Lactobacillus Plantarum and Lactobacillus Paracasei

Fermented milk proteins have been reported to be used for prevention and treatment of various diseases. This study was designed to investigate the anticancer effect of goat milk fermented by Lactobacillus plantarum and Lactobacillus paracasei. In vitro anticancer activity was studied using HeLa cell lines. HeLa cells were treated with milk hydrolysates and incubated at 37C for 4 h and the cell...

Antihypertensive Peptides Specific to Lactobacillus helveticus Fermented Milk

Survival of Lactobacillus casei in the human digestive tract after consumption of fermented milk.

A human trial was carried out to assess the ileal and fecal survival of Lactobacillus casei DN-114 001 ingested in fermented milk. Survival rates were up to 51.2% in the ileum and 28.4% in the feces. The probiotic bacterium has the capacity to survive during its transit through the human gut.
