ISO 15154:2003 specifies a method for the determination of the content of reducing carbohydrates in tobacco by continuous-flow analysis. This method is applicable to manufactured and unmanufactured tobacco.
Abstract
Overview
ISO 15154:2003 - "Tobacco - Determination of the content of reducing carbohydrates - Continuous‑flow analysis method" defines a laboratory procedure to quantify reducing carbohydrates (reducing sugars) in both manufactured and unmanufactured tobacco using a . The method uses a 5% acetic acid extract reacted with in alkaline medium at 85 °C to form a coloured osazone measured spectrophotometrically at . ISO 15154:2003 is intended for quality control, research and regulatory testing where standardized, comparable measurements of reducing carbohydrates are required.
