INTEGRATING THE THAI TRADITIONAL MEDICINE “NINE FLAVORS” CONCEPT INTO FOOD SCIENCE: A CASE STUDY OF NAM PRIK LONG RUEA RICE SEASONING POWDER

Abstract

This study reinterprets the Thai Traditional Medicine framework of the Nine Thai Medicinal Tastes (Nine Flavors) through a structured food chemistry perspective. Rather than treating taste categories as symbolic descriptors, the framework is analytically aligned with dominant compositional domains—including polyphenols, organic acids, ionic solutes, carbohydrates, lipids, and volatile compounds—that collectively shape matrix-level behavior in food systems. Nam Prik Long Ruea, a royal Thai culinary formulation embodying multi-flavor integration, is employed as a case-based illustration translated into a controlled low-moisture rice seasoning powder. Water activity (Aw = 0.15) is reported as a physicochemical boundary descriptor reflecting moisture-state configuration within the particulate matrix. Within the scope of this study, Aw is interpreted strictly as an analytical interface rather than as a shelf-life or microbial stability claim. The study proposes a conceptual bridge through which traditional medicinal–culinary knowledge may be systematically interpreted within contemporary food science without epistemological reduction. By positioning water activity as a measurable interface between compositional chemistry and traditional flavor logic, this work demonstrates how heritage-based knowledge systems may be translated into modern analytical language while maintaining structural and cultural continuity.
