Introduction

Sensory evaluation by "assessors" (see GB/T 10221-1998 2.5), "selected assessors" (see GB/T 10221-1998 of 2.6), the expert evaluators (see GB/T 10221-1998 2.7.1) of three different types of assessors to bear.

This section does not involve product expert or specialist professional products, because of their expertise does not belong to the category sensory capabilities. But the product expert or professional Experts and industry through the specialized training can become an expert assessor. We have the expertise of specialists who can evaluate with other expertise (eg Experience and knowledge of the product being evaluated or processed product market) to interpret sensory data, and draw conclusions.

In the work of the evaluation team, the expert assessors should have a special sensitivity and reproducibility, and has long maintained good sensory memory. must to when in the absence of the control sample, allows the use of reliable comparative judgments.

Expert assessors should form an evaluation team working under the leadership of the evaluation team leader. The evaluation team leader is responsible for the expert Assessor management and training. Expert reviewers are not responsible for selecting the evaluation method, provide samples and interpret the results. The evaluation team leader is responsible for these efforts and decide what information should be provided to team members.
