Recent advances in probiotic research have finally confirmed the healt
h benefits of some probiotic bacterial strains. In addition to their a
pplication to dairy products, probiotic bacteria are now being applied
to new food products including fermented cereals, infant formulae and
therapeutic foods. It is very important to be able to enhance the sta
bility of probiotic bacteria both in old and new applications in order
to expand their new uses and also to guarantee minimum effective dose
s for particular products.
