A review evaluating the potential of underutilized tropical fruits as sources of resistant starches (RS) for the production of short-chain fatty acids (SCFAs) was conducted by researchers from Kyambogo University, Universiti Putra Malaysia, and the University of Sargodha, Pakistan. Resistant starches are non-digestible polysaccharides that function as prebiotics and are known to offer various physiological benefits.
The review highlights how RS undergoes colonic fermentation to produce SCFAs, including acetate, propionate, and butyrate, which have been linked to positive health outcomes such as improved glucose regulation, reduced body weight, and lowered blood pressure. The study also discusses the role of SCFAs in managing metabolic disorders including diabetes, obesity, and hypertension.
Attention is given to factors influencing SCFA yield, such as the structural properties of starches, fermentation conditions, and gut microbiota composition. The review outlines the mechanisms of RS fermentation and examines the physiological impacts of SCFAs derived from fruit-based starches.
The findings suggest that underutilized tropical fruits present a promising and sustainable source of RS, with the potential to enhance gut health and contribute to the development of functional food ingredients. The review supports the value-added use of natural fruit resources in promoting consumer health through dietary interventions.
