5.1 Inspection classification
5.1.1 Type inspection
Type inspection is a comprehensive assessment of the product, and all requirements (indicators) of this standard shall be inspected. Type inspection shall be conducted in any of the following cases:
The difference between the results of the two product inspections is large; a)
b) The production environment has changed significantly due to human or natural conditions; The national quality supervision agency or competent department has put forward type inspection requirements. c)
5.1.2 Delivery inspection
Before each batch of products is delivered, the production unit shall conduct a delivery inspection, and the delivery inspection content shall include packaging, marking and fruit sensory indicators. The sanitary indicators shall determine the inspection items based on the soil environmental background value and the application of pesticides and fertilizers. Only products that pass the inspection and are accompanied by a certificate of conformity can be delivered.
5.2 Batch grouping rules
Watermelons from the same origin and harvested at the same time shall be considered as one inspection batch. 5.3 Sampling method
The sampling method shall be implemented in accordance with the relevant provisions of GB/T8855. 5.4 Judgment rules
NY 5109--2002
5.4.1 When sampling and testing each batch of samples, the defective samples shall be recorded, and the percentage of unqualified shall be calculated according to the weight of the defective fruit. The unqualified rate of each batch of samples shall not exceed 5%. 5.4.2 If one of the sanitary indicators fails to pass the inspection, the batch of products shall be considered unqualified. 5.4.3 If the marking, packaging and weight of the samples of the batch are unqualified, the production unit is allowed to apply for re-inspection once after sorting. No re-inspection shall be conducted for those who fail to meet the sensory and sanitary indicators.
6 Packaging and marking
6.1 Watermelons can be packaged or bulked with corresponding materials according to the size of the fruit and the value of the commodity. 6.2 The same batch of goods must be packaged consistently, and each package must contain watermelons of the same origin, variety and grade. 6.3 The packaging materials of watermelons include cartons, plastic mesh bags, etc. 6.4 Carton: Made of corrugated cardboard, with an appropriate number of ventilation holes on the two ends of the box. The carton pattern should be clear and beautiful, highlighting the style of the product and the brand. Other requirements should comply with GB/T6543. 6.5 When watermelons are packed in cartons, the fruit should be packed individually or in a single layer depending on the size of the fruit. The fruit must be filled to prevent the fruit from shaking in the box. If there are pores, they must be filled with clean and soft materials. If conditions permit, the foam plastic net should be used for packaging before being packed into the carton. The seams of the carton should be sealed with tape.
6.6 Nylon mesh bags must be non-toxic, odorless, pollution-free, strong and firm, not too large, and easy to carry. 6.7 The packaging carton should be printed or labeled on the outside of the box (a logo card should be placed in the nylon mesh bag), indicating the product name, variety, grade, trademark, gross weight, net weight, place of origin and acceptance date. The handwriting should be clear and easy to discern and not easy to fade. 7 Transportation and storage
7.1 Immediately after harvesting, watermelons shall be graded and packaged according to the quality conditions specified in this standard, and delivered and inspected as soon as possible. 7.2 After acceptance, watermelons must be quickly organized for transportation or storage according to the maturity and quality of the fruit, and stored according to grade and quality. 7.3 Watermelons should be handled with care during loading and unloading. The transportation vehicles must be clean and hygienic. When transporting bulk melons, the bottom and surrounding areas of the transportation vehicles in contact with the fruit should be covered with bitter pads to prevent mechanical damage, and should be protected from exposure to the sun and rain during transportation. 7.4 If temporary storage is required, it must be carried out in a cool, ventilated and clean place, and the stacking must be neat to prevent squeezing damage and strictly prevent sun and rain. 7.5 If storage is required for a long time, it should be stored in a low-temperature cold storage, and the temperature should be gradually reduced and pre-cooled before storage. The cold storage should maintain 5℃~6℃ and 85% relative humidity.
7.6 Fruits to be stored for a long time must be clean, free of moisture on the surface, pollution, pests and diseases, and internal injuries. During the storage process, regular inspections should be carried out and diseased fruits should be removed immediately. 7.7 During the storage and transportation of watermelons, it is strictly forbidden to store and transport them together with toxic, odorous, harmful and pest-spreading items. 195
