The optimal preservation of ground green tea leaves hinges on minimizing exposure to elements that degrade its quality. Specifically, protecting it from air, light, heat, and moisture is essential to maintain its vibrant color, flavor, and aroma. Improper management results in oxidation, causing the powder to turn brown, develop a bitter taste, and lose its nutritional value.
Maintaining the quality of this specialized tea powder offers several benefits. Properly stored powder retains its fresh, vegetal taste, allowing for an enjoyable tea experience. Furthermore, preserving the integrity of the powder ensures that its antioxidant properties, particularly those of catechins, remain intact. Historically, careful handling has been integral to preserving delicate teas and herbs, reflecting a long-standing understanding of environmental impacts on sensitive organic compounds.
