Probiotic fermentation of plant based products: possibilities and opportunities

Functional foods are claimed to have several health-specific advantages. In addition to their basic nutritive value, they contain a proper balance of ingredients which help in the prevention and treatment of illnesses and diseases. Within this category, products containing lactic acid bacteria or probiotics are increasingly gaining importance. The recognition of the beneficial effects of dairy products containing probiotics has been well established. The allergy to dairy products, lactose intolerance, and cholesterol content are the major drawbacks related to the use of fermented dairy products for a large percentage of consumers. Modern consumers are increasingly interested in their personal health, and expect the food that they eat to be healthy or even capable of preventing illness. Because of this, probiotic food products made out of fermentation of cereals and fruits and vegetables is receiving attention from the scientific world as well as consumers and constitutes the major part of this review. The use of mathematical models for the probiotic fermentation will help in reducing the time and effort involved in the optimization of the probiotic fermentation process. We have tried to summarize the developments in the use of mathematical models for probiotic fermentation. Future technological prospects exist in innovations which represent solutions for the stability and viability problems of probiotics in new food environments. Current research on novel probiotic formulations and microencapsulation technologies exploiting biological carrier and barrier materials has also been discussed.
