Abstract
Interest in the consumption of food products containing probiotic bacteria, a health promoting intestinal microflora, has seen a large increase in Europe especially in the last two decades. Their popularity, especially the Lactobacilli and the Bifidobacteria has been apparent mostly with dairy products such as fermented milk drinks and yogurts. The use of probiotics was extended to other dairy and food products such as cheese, ice cream, fruit juices, bread etc. Extending the range of products is possible when new strains and micro- or nano-encapsulation are applied which could protect the probiotics from unfavorable surrounding environment. The growth of probiotics is usually slow and it is important to encourage their growth and survival to keep them within the recommended population number of 107-10cfu/g. Improving the growth of probiotics can be achieved by using prebiotics, which are preferentially utilized by probiotics. Research has shown that the use of prebiotics such as inulin and fructooligosaccharides up to 5% enhance the growth and survival of the probiotics during the shelf life of the product. It was found that a low level of milk protein hydrolysis up to 4% using trypsin could also improve their growth. Bifidobacterium animalis ssp lactis (BB12) inoculated in partially hydrolyzed UHT skim milk in the presence of prebiotics shown to have a faster growth rate and better survival ratio up to 28 days stored at 5oC when compared with the control. It is vital that the marketed probiotic products should contain the desirable number of the organisms throughout the shelf life of the product to offer the health benefits anticipated from such products.
