What are Probiotics?
Probiotics were defined by a group of
experts convened by the Food and
Agriculture Organization of the United
Nations (FAO) as
"live micro organisms administered in
adequate amounts which confer a
beneficial health effect on the host".
What are Prebiotics?
specific indigestible substances which
selectively support the growth of
bifidobacteria and possibly other micro
organisms in the intestines.".
e.g. inulin, oligofructose
2
What are Synbiotics?
products in which probiotics and
prebiotics are combined to produce a
synergistically beneficial effect.".
What is a Probiotic foodstuff?
According to probiotic working group of
German Federal Institute for Consumer
Health Protection and Veterinary medicine
BgVV (now BfR):
Probiotic foodstuffs are foods containing
probiotics in an amount sufficient to produce
probiotic effects when such food is ingested.
3
Why add probiotics?
Help to fight bacteria with pathogenic
effects in a natural way and at the same
time,
Beneficial for human and animal
digestive system which supports
general well-being
Why add probiotics?
Also..
The EU market alone for probiotics and
yoghurts was worth Ł 8 bn in the first half of
decade.
high consumer demand
market worth over 10 bn by 2010
growth in food market 1 2 % per year!

Probiotic cultures
Traditional cultures used:
L. acidophilus group L. acidophilus and L.
johnsonii
L. casei group & L. reuteri
Bifidobacterium spp. B. animalis [B.
bifidum], B. longum, B. lactis, B. infantis, B.
breve
Situation in Italia
Definitions of pre- and probiotics
Widely accepted in food supplements >50 on the market
Yogurt - probiotic cultures must not substitute the fermentative
action of Lactobacillus bulgaricus and Streptococcus
thermophilus
When fermentation process is just carried out by other cultures
yogurt but fermented milk

Hungaricus 2-51 of Dairy products
Use of pro- and prebiotics widely used and
accepted in foods and food supplements in
Hungary
ca. 40 food supplement products
Situation in Deutschland
Use of pro- and prebiotics widely used and
accepted in Germany
ca. 40 food supplement products, whereas

Situación en Espańa
No existing legislation or guidance for prebiotics and probiotics
According to survey (2003), every year 16 % increase in sales of pre-
and probiotic products
Prebiotics (Fructooligosaccharides-FOS) are added among others to
dairy products, beverages, biscuits and bread
At present time the only probiotic foodstuff in the market are :
Yogurt, exclusively with Streptococcus thermophilus and
Lactobacillus bulgaricus or acidofilus
other fermented milks with Bifidobacteria, Lactobacillus casei
inmunitass, etc.
Drinks containing fruit juices, fermented milk and bacterial cultures.
EFSA Qualified Presumption of
Safety
Working document (2003) On a generic approach to the safety
assessment of microorganisms used in feed/food and feed/food
production proposed QPS a system to evaluate groups of
microorganisms to use as basis for establishing safety of
individual products
Aim to harmonise situation without introducing unnecessary
legislative burden, but allowing for safety concerns to be
addressed
Address lack of harmonisation, proportionality (is there really
a risk?) and recognition of familiarity of microorganism
ntended as similar to USA s GRAS system
I
Streamline and provide quicker route to market for safe
microorganisms
7
QPS - Principles
A group of organisms could be considered safe for use, provided:
Their identity could be establishedtaxonomy
There is sufficient familiarity on which to establish safety
Body of knowledge
There are no known pathogenic strains (or knowledge allows
to exclude existence of these)
Strains given QPS status would still be subject to qualifications
safe provided that& (absence of antibiotic resistance,
restricted use etc.)
Strains not meeting conditions for QPS assessed case-by-case
QPS - Principles
Closed consultation in March 2007:
List of microorganisms already notified to EFSA
List of taxonomic units proposed for QPS status
Assessment of Bacillus Bacteria with respect to QPS
Assessment of gram positive non-sporulating bacteria
with respect to QPS
Assessment of yeasts with respect to QPS
Assessment of filamentous fungi with respect to QPS
