Sustainable production and characterization of almond butter added oat-flaxseed food bar rich in bioactive content

Abstract

• Food bars are functional food formulations with health promoting potential • Successful enrichment of oat-based food bar with almond butter and flaxseed • Bars with 70% almond butter exhibited highest phenolic and antioxidant potential • Antioxidants rich food bar presented lower microbial counts during storage Value added food bars rich in bioactive and antioxidant content developed by diverse amalgamations of agro-industrial products offer numerous health benefits that extend beyond basic nutritional value. The objective of this research was to develop and evaluate flaxseed food bars with 70% (T 1 ), 60% (T 2 ) and 50% almond butter (T 3 ). The study also aimed to explore their physicochemical, microbial, sensory as well as antioxidant attributes throughout a 60-day storage. Results re
