Characterization and discrimination of Indian propolis based on physico-chemical, techno-functional, thermal and textural properties: A multivariate approach

Objective: The present study assessed physico-chemical, techno-functional, thermal and textural characteristics of propolis samples (n = 30) collected from four Northern zones of India. Methods: The propolis samples were analyzed according to the Association of Official Analytical Chemists (AOAC) official protocols for their ash, moisture, and protein content. Soxtech, Fiber tech, Hunter LAB Colorimeter, TA.XT2i Texture Analyzer, Thermo gravimetric Analyzer, Discovery DSC 25 have been used to assess the crude fat, fibre content, colour, texture and thermal properties, respectively. Results and conclusions: Physico-chemical properties of propolis differed significantly (p
