Sugestão de protocolo para controle de qualidade microbiológico em alimentos contendo Lactobacillus acidophillus e Bifidobacterium bifidum

Abstract

Bacteria such as Bifidobacteria and Lactobacilli are important to human health, because when consumed, can increase the number and activity of intestinal microorganisms with useful properties to the host. Many diseases that these bacteria are beneficial, helping the formation of so-called probiotic in the gut barrier, thus preventing microbial colonization by pathogenic bacteria.Some of the mechanisms described for this impediment is the competition in the intestine favors the stimulation of the immune system thereby facilitating the body's defense. Foods that contain probiotics are called functional foods, such as fermented milk that help today's people with colon cancer, Cronh disease, diarrhea caused by viruses and bacteria and traveler's diarrhea. However, for these same bacteria are truly effective, they must be resistant to gastric juice and bile, so that they reach the viable intestinal environment and perform their duties. This study aims to suggest a protocol for microbiological control of foods containing Lactobacillus acidophilus and Bifidumbacteria sp.
