Probiotic Functional chocolate for better health The future is now in Probiotic Functional Foods Probiotic 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 The growing importance of In only four years, the European market for fortified and functional foods functional foods has risen from less than € 25 billion in 2002 to € 40 billion in 2006. This massive jump Natural functional foods exist in virtually every food group. includes products aimed at improved digestive system, But perhaps most importantly, foods and beverages can cardiovascular health, improved immune system, a healthier now be fortified and enhanced by manufacturers to give brain and nervous system, bone health and beauty benefits. their products added health benefits never before possible. New food products are being developed with beneficial Consumers are using functional foods to increase their feeling components that are attracting a significant share in all of well-being. In the US, 41% of all respondents indicated segments of the food and beverage market. The market that they supplemented their diets with additional vitamins, leaders and trendsetters have recognized that consumers minerals and other dietary supplements. Over the past year, are learning to take control of their health through the food that figure for Europeans increased to 31%. The US market choices they make. for nutraceuticals - functional foods and drinks with specific added ingredients - has been forecast to grow at an annual rate of 5.3% between 2005 and 2010. The European market Phenomenal growth rates is expected to grow even faster. Consumers now enjoy a sense of guilt-free indulgence accompanied by genuine There is a vast evolution - some might even say revolution - health benefits. taking place in functional food trends around the world. Probiotics fit perfectly into this rapidly expanding market.

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 Probiotic 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. 5 How do Probiotics work? Probiotic The human gastrointestinal tract contains an extremely other drugs, excess alcohol, stress, disease and exposure to complex and diverse population of bacteria. While the certain toxic substances. When this happens, harmful majority of these micro-organisms are either helpful or bacteria have an environment in which they can thrive, benign, some have the potential to cause disease. In healthy leading to a proliferation of undesirable or disease causing individuals, there is an optimal bacterial balance in the bacteria. This increases the risk of clinical disorders such as intestinal tract. However, a wide range of circumstances can inflammatory, infectious and other diseases. upset this balance. These include the use of antibiotics and stomach small intestine large intestine bad micro-organism good micro-organism Probiotic bacterial cultures in food or as supplements assist the body in re-establishing the proper balance necessary for optimal intestinal function and good health. 6 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 7 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. Market research A majority of new products launched within the functional food segment focus on digestive claims.
