Experiment code 20.6.3.26
Experiment Title Physical properties and chemical composition influenced by drying methods in turmeric
Research Type Departmental Research
Experiment Background The choice of drying methods significantly influences the quality of turmeric (Curcuma longa L.), a medicinal herb rich in bioactive compounds such as curcumin. The motivation behind this study lies in the practical applications of turmeric in traditional medicine, culinary practices, and the pharmaceutical industry. With various drying methods commonly employed in the herbal industry, there is a need to systematically examine their effects on physicochemical characteristics, essential oil yield, and volatile composition of turmeric. Physicochemical attributes like color, texture, and moisture content are crucial indicators of overall quality. Essential oil yield, contributing to turmeric's aroma and therapeutic properties, may vary with different drying methods. The volatile composition, comprising diverse secondary metabolites, could be altered during drying, impacting sensory and medicinal qualities. This research will enhance our understanding of optimal drying techniques for turmeric, facilitating improved quality and broader applications in traditional medicine, culinary practices, and the pharmaceutical industry.
