6.1.1 Inspection for export
NY/T 7022003
Unit: mg/kg
Color, aroma, flower integrity, inclusions, foreign matter outside plants, uniformity, moisture, α-acid and other inspection items are mandatory inspection items. 6.1.2 Type inspection
6.1.2.1 Type inspection items are all items. 6.1.2.2 Type inspection shall be carried out in any of the following cases: a) When replacing equipment or resuming production after a long-term shutdown; b) When there is a large difference between the factory inspection result and the last type inspection; c) When there is a large fluctuation in the characteristic limit index; d) When the national quality supervision agency conducts a random inspection. 6.2 Batch
6.2.1 The same variety of hops from the same production unit, which are picked, roasted, and packaged in the same period, have the same batch number. Each production unit shall number them in sequence from the first package of production every year, and indicate the production date. 6.2.2 The batch size of each batch of compressed hops is 100 packages. 6.2.3 The granular hops shall have the same batch number if they are produced in the same shift and the same production line and are in good packaging, and the processing date shall be indicated. 6.3 Sampling
According to the provisions of Chapter 3 of QB/T3770,2-1999. 6.4 Judgment Rules
6.4.1 If the hygiene index, the detection of pesticides banned by the state, and the α-acid are unqualified, the batch of products shall be judged as unqualified products. 6.4.2 For superior products, one of the indicators such as color, aroma, flower body integrity, inclusions, plant foreign matter, and uniformity can be allowed to meet the requirements of first-level products, and the other indicators should meet the requirements of superior products. For first-level products, one of the indicators such as color, aroma, flower body integrity, inclusions, plant foreign matter, and uniformity can be allowed to meet the requirements of second-level products, and the other indicators should meet the requirements of first-level products; for second-level products, one of the indicators such as color, aroma, flower body integrity, inclusions, plant foreign matter, and uniformity can be allowed to fail to meet the requirements of second-level products, and the other indicators should meet the requirements of second-level products. 7 Marking

8.1 Packaging
8.1.1 Packaging materials and containers
8.1.1.1 The compressed hops bag is lined with kraft paper and polyethylene plastic film, and covered with white cloth and linen. Three bamboo strips are placed on the front and back of the bag, and six blue steel hoops are made. The packaging should be tight and neat, without seams or broken bags. 8.1.1.2 Pellet hops shall be packaged in polyethylene plastic bags or aluminum composite packaging bags lined with polyethylene, or in polyethylene plastic barrels or tinplate barrels. They shall be packed in vacuum or filled with volatile gas. The composite bags shall not be deformed or damaged, and the seals shall not leak. 8.1.2 Packaging and measurement
8.1.2.1 Compressed hops
The net content of each package of compressed hops shall be determined according to the equipment and conditions of each unit, but the net content shall not have negative deviations. The packaging of other specifications shall be carried out in accordance with the "Regulations on the Supervision of Measurement of Quantitatively Packaged Commodities". 8.1.2.2 Hop pellets
The net content of each bag (barrel) can be determined according to the size of the bag (barrel), and it is advisable to implement it in accordance with the "Regulations on Metrology Supervision of Quantitative Packaged Goods". 8.2 Transportation
8.2.1 During transportation, it should be tightly covered with a canopy or use a closed compartment. The bottom of the closed warehouse should be padded with a certain height of impermeable material.
8.2.2 It should not be transported in the same warehouse or compartment with odorous and toxic items. 8.3 Storage
It should be stored in a dry, light-proof environment below 4°C. The bottom of the goods should be padded with a certain height of impermeable material. The height should be based on the principle of ensuring safety. Open-air storage is strictly prohibited.
