3.5 Requirements for raw materials
3.5.1 With sugar cane as raw material

3.6 Requirements for quantitative packaging
The net content shall meet the requirements of Measures for the metrological supervision and administration of quantitatively packed commodities.
4 Test methods
4.1 Sensory items
The color, taste, smell and state shall be determined in accordance with the method specified in GB 13104. The grain size and dark spots shall be determined in accordance with the method specified in GB/T 35887.
4.2 Physical and chemical items
The sucrose content, reducing sugar content, conductometric ash content, drying loss, color value, turbidity and water-insoluble impurities shall be determined in accordance with the method specified in GB/T 35887.
4.3 Food safety requirements
They shall be determined in accordance with the method specified in GB 13104.
4.4 Net content
It shall be determined in accordance with the method specified in JJF 1070.
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.
