The document discusses the concepts of probiotics, prebiotics, and synbiotics, defining each term and elaborating on their characteristics and health benefits. Probiotics are beneficial bacteria, while prebiotics are non-digestible food ingredients that promote their growth; synbiotics are a combination of both designed to enhance their effects. It highlights various sources, mechanisms, and health impacts such as improved gut health, reduced diarrhea, and protective effects against certain diseases.

9. PREBIOTIC
S
• Consept was first introduced by Glenn Gibson and Marcel Roberfroid in 1995
• defined as " a non digestible food ingredient that beneficially affects the host by
selectively stimulating the growth/ or activity of limited bacteria in colon and
thus improves host helath"
PREBIOTICS
( substrate for
probiotic)
Probiotics
(Good
bacteria)
Pathogen
(Harmful
bacteria)

10. CHARACTERISTIC OF PREBIOTIC
Should be resistant to
the action of
acid, bile, hydrolyzing
enzymes
Should not be absorbed
in upper gastrointestinal
tract
Should be easily
fermentable by
Beneficial intestinal
microflora
• An ideal prebiotic should
be;

11. SOURCES OF PREBIOTIC
• Some of the sources of prebiotic include;
• Inulin sources like chicory root
• non-digestible carbohydrates like;
fructo-oligosaccharide (FOS)
galacto-oligosaccharide(GOS).
transgalacto-oligosaccharide

12. EFFECTS OF PREBIOTIC
• Fermentation of Prebiotics by gut microbiota produce short chain fatty acids
including lactic acid, butyric acid, and propionic acid have multiple effects.
• Prebiotics exibit helath effect like reducing duration of diarrhoea also gives relief
from inflammation also symptoms associated intestinal bowel disorder also
protective effect on colon cancer
• peptidoglycan is prebiotic fermentation product stimulate innate immune system
against pathogenic microorganisms.
• Helps in lactose intolerance, constipation , maintain helath gut

13. SYNBIOTICs
• A synbiotic is defined as
" mixture of probiotics and prebiotic
that beneficially affect the host by
improving the survival and activity of
beneficial microorganisms in gut"

14. • When Gibson introduced the concept of prebiotics he speculated as to the
additional benefits if prebiotics were combined with probiotics to form what he
termed as Synbiotics.
• the word “synbiotics” alludes to synergism, this term should be reserved for
products where the prebiotic compounds selectively favor the probiotic
organism.
• Synbiotics were developed to overcome possible survival difficulties for
probiotics.
• Several factors like pH, H2O2, organic acids, oxygen, moisture stress etc. have
been claimed to affect the viability of probiotics
• Synbiotics may be complementary synbiotics synergistic synbiotics

15. EFFECTS OF SYNBIOTIC
• The most important and documented beneficial effects of probiotics include the
prevention of diarrhea, constipation.
• a stimulating effect of the growth of probiotics and ubiquitous bacteria contribute
to maintain the intestinal homeostasis and a healthy body
• enhancement of anti-bacterial activity, is anti-inflammatory.
• Blocking of adhesion sites for pathogenic bacteria.
• Increasing levels of lactobacilli and bifidobacteria and balanced gut microbiota

16. EXAMPLES OF SYNBIOTIC
• Bifidobacteria and Fructooligosaccharides (FOS)
• Bifidobacteria or lactobacilli with FOS or inulins or galactooligosaccharides
(GOS)
• Lactobacillus rhamnosus GG and inulins
