1 Scope

GB/T 12104-2022 is the Chinese national standard on terminology of starch and starch derivatives, in the field of food technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 14 October 2022 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2023. Classification: ICS 67.180.20, CCS X11. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document defines common terms for starch and its derivatives. This document is applicable to the sales, scientific research and inspection of starch and its derivatives.

3 General terms

3.1 Starch A carbohydrate that exists in some plant organisms or microorganisms in the form of particles, and is alpha-D-glucopyranose through alpha-1,4- Polysaccharide molecules connected by glycosidic bonds and alpha-1,6-glycosidic bonds.

3.2 native starch Unmodified starch extracted from plants or microorganisms by physical or other means.

3.3 Free starch freestarch During the starch extraction process, the starch that can be separated and extracted from the free coexisting components.

3.4 Combined starch boundstarch linked starch Starch that cannot be separated from the raw material by mechanical means during the starch extraction process.

3.5 damaged starch damagedstarch Starch granules damaged by external force during processing.

3.6 thermaldamagedstarch Partially gelatinized starch granules are caused by the high temperature action of the raw materials for starch production in the drying process or starch production process.

3.7 Modified starch modifiedstarch modified starch After physical, chemical or biological treatment, new functional groups are introduced into the original starch molecules or the size of starch molecules and starch granules are changed. product of granular structure.
