BS ISO 19563:2017

Overview

BS ISO 19563:2017 specifies a method for the determination of theanine in tea and instant tea in solid form using high-performance liquid chromatography (HPLC). Theanine, an amino acid found predominantly in tea leaves, is known for its potential health benefits, including stress reduction and cognitive enhancement. Accurate measurement of theanine content is essential for quality control, product formulation, and nutritional labelling in the food technology sector.

Key Requirements

This standard outlines the procedures necessary to ensure reliable and reproducible results when measuring theanine levels. Key requirements include:

• Preparation of tea samples and extraction of theanine using appropriate solvents.
• Calibration of HPLC equipment to ensure accurate quantification.
• Validation of the method through precision and accuracy checks.
• Documentation of results in accordance with regulatory standards.

By adhering to these requirements, laboratories can ensure that their testing methods are robust and compliant with international standards.

Implementation Benefits

Implementing BS ISO 19563:2017 provides several advantages for organisations involved in tea production and analysis:

• Quality Assurance: Regular testing for theanine content helps maintain product quality and consistency.
• Regulatory Compliance: Compliance with this standard supports adherence to food safety regulations and labelling requirements.
• Market Differentiation: Accurate measurement of theanine can enhance product marketing by highlighting health benefits.
• Research and Development: The standard facilitates research into the health effects of theanine, supporting innovation in product development.

Organisations that implement this standard can enhance their credibility and reputation in the marketplace.

Compliance Value

Compliance with BS ISO 19563:2017 is crucial for businesses aiming to meet both consumer expectations and regulatory requirements. The standard provides a framework for:

• Ensuring the accuracy of nutritional information provided to consumers.
• Facilitating international trade by aligning with global standards.
• Reducing the risk of non-compliance penalties through rigorous testing protocols.

By following this standard, companies can demonstrate their commitment to quality and safety in the food technology sector, ultimately leading to improved consumer trust and business sustainability.
