GB/T 16860-2025Sensory analysis methodology - Texture profile (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents".

Drafting.

This document replaces GB/T 16860-1997 "Sensory Analysis Methods - Texture Profile Inspection". Compared with GB/T 16860-1997, except for...

Aside from structural adjustments and editorial changes, the main technical changes are as follows.

a) The terms "mechanical properties," "geometric properties," and "surface properties" have been removed (see 3.2, 3.3, and 3.4 of the 1997 edition);

b) A new sampling method has been added (see 5.2);

c) The content in "Order of Feature Appearance" has been changed (see 6.1, 1997 version 6.1);

d) The definition and evaluation techniques for mechanical properties have been changed (see Table 1, 1997 edition);

e) Reference samples for product geometry have been removed (see Table 2 in the 1997 edition);

f) The content of the "Reference Sample Selection Criteria" has been modified (see 6.4.2, 1997 version 6.4.2);

g) The content of the "Texture Evaluation Process" has been changed (see Figure 1, Figure 1 of the 1997 version);

h) The selection process for the evaluation panel has been enhanced (see 7.2).

This document is equivalent to ISO 11036:2020 "Sensory analysis methodology - texture profile".

The following minimal editorial changes have been made to this document.

a) To align with existing standards, the standard name will be changed to "Sensory Analysis Methods for Texture Profile Inspection";

b) Change "6.2.1~6.2.3" in section 6.2.1 to "6.2.2~6.2.4" to correct the original text error;

c) Change "ISO 13299" to "ISO 8586" in 7.3 to correct the original error.

1 Scope

This document describes a method for establishing a product texture profile, covering all the steps involved in comprehensively establishing the product's texture characteristics.

This document applies to food (solid, semi-solid, and liquid) or non-food products (such as cosmetics).

The main applications of this document include the following.

---Selection and training of evaluators;

---Establish definitions and evaluation techniques for product texture characteristics, and provide guidance to evaluators;

---Identify key characteristics in the product's texture properties and establish a standard texture profile to identify any changes in the product over time;

---Optimize existing products and develop new products;

---Study various factors that may affect the texture characteristics of a product, such as manufacturing process, time, temperature, ingredients, packaging, shelf life, and storage.

conditions etc;

---Compare similar products to identify differences in texture and strength;

---Analyze the correlation between sensory evaluation and instrumental and/or physical measurements.
