title: Fermented cereal beverages: from probiotic, prebiotic and synbiotic towards Nanoscience designed healthy drinks.
abstract: The consumption of fermented foods by human kind goes a long way back in history and there are as many types of fermented food as civilizations. Food Science and Technology has progressed from designing nutritional foods towards food with health improvement characteristics such as functional foods. In this sense, the area of food with properties to improve gastrointestinal health such as probiotics, prebiotics and synbiotics has been the most important segment within functional foods. Most of these products are dairy-based so the development of nondairy gut improvement products has been of great interest for the food industry, resulting in the rise of cereal-based probiotic and synbiotic products. Finally, through Nanoscience and the application of Nanotechnology techniques in the food sector, it has been possible to design fermented beverages with synbiotic properties, and the incorporation of nanoparticles with unique and specific bioactivity, which has opened a new horizon in this segment of food created to improve human health and well-being.
  
  
  CONCLUSIONS
  There is currently a great interest in producing healthy food in particular that which has an impact in improving the gastrointestinal health such as probiotics, prebiotics and synbiotics. Most of these functional foods are dairy based and have been greatly accepted worldwide. Nevertheless, there has been a need for the development of nondairy probiotic, prebiotic and synbiotic products. This has encouraged food scientists to study the feasibility of applying other fermenting substrates such as cereals for the development of innovative nondairy fermented functional foods. Therefore, in this review we have addressed the significance of applying cereals and their fractions for the development of probiotic, prebiotic and synbiotic beverages. Furthermore, we have presented the importance of including nanoscience and nanotechnology techniques for the creation of fermented cereal beverages that contain specific bioactive nanoparticles. Thus, this work provides the guidelines to promote the development of novel nano-designed fermented cereal beverages that could significantly have an impact on the health of the consumers.
