Novel approach to upcycling food processing biomass: development of rice snacks using rice bran emulsifier

Abstract

This study addresses the need for innovative approaches to upcycling rice bran as a biomass resource. A novel upcycling ingredient derived from rice bran was developed, and its application in the production of rice crackers with enhanced texture was explored. The effects of different emulsifier types and concentrations on the texture, flavor, and overall quality of rice crackers—by influencing the uniformity of oil and moisture in the formulation—were confirmed through systematic analytical methods. These methods included spreadability tests, peak strength measurements, oil loss content analysis, SEM, and distribution of the carbon source studies. The addition of rice bran-derived emulsifiers significantly improved the texture of crackers, imparting desirable crunchiness and mouthfeel. This study highlights the valorization of rice byproducts by developing value-added ingredients and their application in innovative food products. This approach contributes to sustainable food production, reduces waste in the rice industry, and promotes a circular economy.
