            Today’s consumer is far more sophisticated and knowledgeable
            about food than ever before. They have learned that what they
            buy and eat can provide specific health benefits that go far beyond
            just basic nutritional requirements. The modern consumer has
            discovered functional foods.




                                                                                  2

What are   Probiotics?




              In the simplest terms, a probiotic is a living beneficial micro-organism,
              it can be a bacterium or yeast . Certain micro-organisms living in the
              human intestinal tract are essential for good health.


              The World Health Organization defines probiotics as
              “Live micro-organisms which when administered in adequate
              amounts confer a health benefit on the host.”

              The word probiotic comes from the Greek and means ‘fit for life’ or
              ‘pro-life.’ While much of the progress against disease over the past two
              centuries has involved the discovery and use of antibiotics, public health
              and medical researchers now foresee revolutionary progress on a similar
              scale for probiotics.


              Probiotics, when eaten, induce health benefits by beneficially affecting
              the balance of the intestinal microflora (or microbiota). While interest in
              the health promoting aspects of probiotics goes all the way back to the
              start of the 20th century, scientists have made huge progress in recent
              years in identifying their potentially beneficial roles in health.




              There are three main attributes of a probiotic:


                • The micro-organisms (bacteria or yeast) need to be alive
                • The micro-organisms have to be ingested orally
                • The micro-organisms must be capable of reaching the large
                 intestine alive, in order to have an effect on the microbial balance




                                                                                            4

    Characteristics
    and considerations for health

    Probiotic micro-organisms have to be tough.
    They must be able to resist the acid environment of the stomach,
    have a good bile tolerance, be capable of growing without oxygen and be
    non-toxic. There are only a few bacterial species that can be used in oral
    supplementation and as food additives. These include species belonging
    to the Lactobacillus, Streptococcus, and Bifidobacterium groups or
    genera, along with some other genera of Bacillus and yeasts. These are
    all naturally present in the intestine as well as in certain fermented dairy
    products.


    The probiotic bacteria in the intestinal tract generate intense metabolic
    activity and are absolutely essential for overall human health. Besides
    promoting normal gastrointestinal functions and providing protection
    against infection, they also affect metabolism and immune function.

    Probiotics by the numbers

    The sheer number of probiotic bacteria at work in the intestinal tract is almost beyond
    imagining. In fact, there are ten times more bacteria working in the human gut than there
    are cells in the entire human body.
    • The adult intestinal tract is home to approximately 100 trillion micro-organisms
    • More than 400 different bacterial species have already been identified in the intestinal tract

       Barry Callebaut’s strong connection to
       scientific and consumer
       evidence
Barry Callebaut & probiotics: a unique combination

In recent years, Barry Callebaut has been a world leader in the scientific exploration of
the health benefits of the many previously untapped properties of cocoa and chocolate
products. Our researchers are now bringing the full force of their scientific and innovation
skills to bear on probiotics. Numerous stability and clinical studies have been conducted or
are underway.


There are major challenges to incorporating probiotics into liquid chocolate and chocolate
related products on an industrial scale.
• One of these is that products need to be maintained at a temperature that does not kill
 the probiotic. This requires a narrow temperature range that is lower than that normally
 used, making it difficult to achieve effective mixing and proper probiotic dispersion.
• Our new large scale process has the advantage that machines can be easily cleaned. This
 eliminates the carry over of probiotics when the same machine is used for making other
 products.


This unique probiotic process is a proprietary method developed and
patented by Barry Callebaut.

     Major           advantages



     Products combining probiotics with Barry Callebaut
     chocolate offer major advantages for the health-
     conscious consumer:


     • Probiotics have no influence whatsoever on the taste,
       texture or mouth feel of the end product. Your
       product will have the same great taste Barry Callebaut
       has always been famous for.
     • A long shelf life - up to 1 year - depending upon the
       product
     • Products do not have to be refrigerated
     • Encapsulation for maximum resistance against
       stomach acid and better activity in the intestinal tract
     • Chocolate is a stable environment for probiotics
     • Only a minimum quantity per day (13.5 g) is required
       for optimal activity
     • A wide range of applications is possible




                         The future is now for probiotic functional foods.
                         A strong and rapidly growing base exists for
                         probiotics in the current global food market.
