Animal and vegetable fats and oils — Determination of fatty-acid-bound chloropropanediols (MCPDs) and glycidol by GC/MS — Part 3: Method using acid transesterification and measurement for 2-MCPD, 3-MCPD and glycidol
Scope:
This document specifies a procedure for the simultaneous determination of 2-MCPD esters (bound 2-MCPD), 3‐MCPD esters (bound 3‐MCPD) and glycidyl esters (bound glycidol) in a single assay, based on acid catalysed ester cleavage and derivatization of cleaved (free) analytes with phenylboronic acid (PBA) prior to GC/MS analysis.
This document is applicable to solid and liquid fats and oils. For all three analytes the limit of quantification (LOQ) is 0,1 mg/kg and the limit of detection (LOD) is 0,03 mg/kg.

Sensory analysis — Methodology — Balanced incomplete block designs
Scope:
This document specifies a method for the application of balanced incomplete block designs to sensory descriptive and hedonic tests.
This document is applicable when the number of test samples exceeds the number of evaluations that an assessor can perform reliably in a single session.
This document also specifies the fundamental characteristics of balanced incomplete block designs and establishes guidelines for their application in sensory evaluation.
