感官分析 方法 一般导则（ISO 6658:2017 等同采用）

[中文适用范围]： 本文件提供了感官分析使用的通用指南。它描述了通过感官分析检查食品和其他产品的测试，并包括有关如果需要统计分析结果时使用的技术的一些通用信息。通常，这些测试仅用于客观感官分析。但是，如果测试可用于确定偏好（在享乐测试中），则予以说明。享乐测试旨在确定产品的可接受性和/或通过指定的消费群体确定两个或多个产品之间的偏好。这些方法对于确定是否存在可感知的偏好（喜好程度的差异）或是否存在不可感知的偏好（配对相似性测试）是有效的。享乐测试的通用指南见ISO 11136。 [外文原描述]： ISO 6658:2017 gives general guidance on the use of sensory analysis. It describes tests for the examination of foods and other products by sensory analysis, and includes some general information on the techniques to be used if statistical analysis of the results is required. Generally these tests are intended only for objective sensory analysis. However, if a test can be used for determining preference in hedonic test, this is indicated. A hedonic test aims to determine the acceptability of the products and/or to determine preferences among two or more products by the specified consumer population. The methods are effective for determining whether a perceptible preference exists (difference in degree of liking), or whether no perceptible preference exists (paired similarity test). General guidance for hedonic tests is given in ISO 11136.
