Probiotics are defined as live organisms that, when administered in adequate amounts, can confer health benefits to the host. In order to benefit human health, probiotics must be viable and metabolically active from processing to food consumption. Lactic acid bacteria were the first probiotic microorganisms commercially exploited. Despite this, there have been several technological shortcomings associated to their application in foods. These limitations are related to the sensibility of lactic acid bacteria to lethal and sub lethal steps faced during food processing, such as, pasteurization, baking, refrigeration, pH reduction, presence of preservatives, drying, among others. Thus, spore-forming probiotic microorganisms may greatly contribute to overcome the limitations related to the application of non-spore forming bacteria (lactic acid bacteria) in foods, and may allow the development of innovative formulations. In spite of their potential, there are no studies focused on the evaluation of the behavior of spore-forming probiotic microorganisms during processing and storage of foods, such as requeijao. Studies aiming to assess the health benefits associated to the consumption of spore-forming probiotic microorganisms are also still scarce. Therefore, the current project aims: i) to use predictive models to quantify the survival (functionality) of probiotic microorganisms (Bacillus, Lactobacillus, e Bifidobacterium) exposed to simulated gastrointestinal fluids, under dynamic conditions and ii) to assess the behavior of a probiotic Bacillus strain during processing and storage of requeijao as well as to elucidate the health benefits linked to consumption of this food [by assessing blood biochemical parameters, immune system and glycemic metabolism proteins, and endogenous antioxidant systems (superoxide dismutase and catalase) of Wistar male rats].
