Abstract
Overview
ISO 5642:2024 establishes the international standard for tea polyphenol extracts, defining their classification and specifying basic quality requirements. These extracts, derived from Camellia sinensis leaves through green extraction processes, are valued for their high antioxidant content, particularly catechins and total polyphenols. This standard applies specifically to tea polyphenol extracts in solid form, providing a globally recognized framework for grading and quality assessment based on chemical characteristics.
