This standard is developed in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 317-2006 White granulated sugar. In addition to a number of editorial changes, the following main technical changes have been made with respect to GB/T 317-2006:
——The requirements of dark spot are added (see 3.2.3);
——The food safety requirements are modified (see 3.4; 3.4 of Edition 2006).
——The requirements for raw materials are added (see 3.5);
——The test methods for sensory items and physical and chemical items are modified (see clause 4; clause 4 of Edition 2006);
——The inspection rules are modified (see clause 5; clause 5 of Edition 2006).
This standard is redrafted by reference to but is not equivalent to Codex Stan212-1999 Codex standard for sugars of CAC.
This standard was proposed by China National Light Industry Council.
This standard is under the jurisdiction of SAC/TC 373 National Technical Committee on Sugaring of Standardization Administration of China.
The previous editions replaced by this standard are as follows:
——GB 317-1984, GB 317-1998 and GB/T 317-2006;
——GB 317.1-1991;
——GB 317.2-1991.

5 Inspection rules
5.1 Type inspection
5.1.1 After being separated, each tin of the massecuite shall be numbered. While weighing the package, continuously collect about 3kg of sample and put it in a container with a lid, mix it uniformly to use it as the numbered sample; in addition to using this sample for numbered analysis, take other 0.5kg of sample in a container with a lid and accumulate for 24h to make the daily collected sample.
Take 1.5kg of daily collected sample, seal it with food grade plastic bag or fill it into a glass stoppered bottles, with the product No., level, production date, sample base, inspection result and the inspector marked; preserve the bag or bottle in a dry and ventilated environment for self-inspection of factory and quality supervision and inspection. It may be used as the reserved sample for arbitration inspection through the agreement of the supplier and the demander, and the result of single sampling inspection or arbitration inspection is effective for the sugar delivered successively with the same serial number.
5.1.2 Under the premise of ensuring stable product quality, the manufacturer may carry out random inspection for each numbered sample according to the actual production situation and the inspection items include: sucrose content, reducing sugar content, conductometric ash, drying loss, color value, turbidity, water-insoluble impurities and all items required in the physical and chemical inspection on daily collected samples; if one or more items of the inspection results fail to meet the requirements of a particular level, the sample will be treated according to the requirements for the actually reached level, and those failing to reach the index of Level 2 white granulated sugar will be treated as rejected products.
5.1.3 Under one of the following conditions, all the items in the technical requirements shall be inspected and the inspection result is regarded as the comprehensive assessment of product quality:
a) trial production and stereotyping appraisement of new products or for transfer-plant production of products.
b) the beginning of the production period or the production resumption after washing;
c) early, intermediate and later stages of normal production;
d) in case of unacceptable batch in acceptance inspection;
e) the relative large change of raw materials and process may affect the product quality
f) the quality supervision organization requires to carry out the inspection.
