Abstract:Traditional sun-drying of Bor-thekera (Garcinia pedunculata Roxb.) fruit slices for consumption and long-term storage are practiced in Assam and other Northeastern states of India. The indigenous communities of the region have a long-held belief that the medicinal value of the dried slices increases with ageing. However, there are limited studies that bridge the gap between this indigenous knowledge with food science. The present study, therefore, aims to investigate the effects of ageing on physicochemical, functional, phenolic, antioxidant, and sensory attributes of traditionally processed Bor-thekera slices. Fresh-dried (FDGP; collected in April 2025) and stored-dried Garcinia pedunculata (SDGP; collected in April 2021) samples were studied. The total phenolic content (6.23 ± 0.018 mg GAE/g) and DPPH scavenging activity (76.54 ± 0.156%) revealed that the SDGP samples retained significantly higher phenolic content than FDGP samples (p< 0.05); cold-water extraction minimized the degradation or loss of heat-sensitive compounds. The functional integrity of the samples was supported by FTIR spectra. Sensory assessment involving a limited panel size demonstrated that the taste and color of SDGP water infusions were preferable and received good overall acceptability. Thus, these findings scientifically relate to the traditional belief on the ageing of sun-dried Bor-thekera, providing partial scientific support for its stability and potential functional value.
