Abstract

Globally, grains such as wheat, rice, maize, oat, barley, rye, sorghum, millet, buckwheat, and quinoa are planted for producing dietary foods and consumed in whole, polished, or milled forms. Recent studies in nutrition and epidemiology suggest that whole grains offer health benefits to humans and, as a result, their consumption has significantly increased. Controlled germination is one of the effective methods to enhance the nutritional value of whole grains. In this chapter, the term controlled germination refers to: germination under carefully controlled conditions, and germination accompanied by the application of environmental stresses that trigger plant defense systems in order to produce and accumulate health-promoting bioactive compounds. This chapter summarizes the research on conventional methods of germination control (germination time, temperature, and oxygen), and the impacts of these treatments on the nutritional quality of sprouted grains. It also reviews the emerging use of physical energy forms such as ultrasound, high pressure, pulsed electric field (PEF), light, and cold plasma, among others, as new controlled germination enhancers.
