Test method
Table 3 Hygiene index
NY/T 692—2003
Indicator/（mg/kg）
Randomly weigh 3kg~4kg of fruit samples from the sample for inspection. The inspection is carried out in the order of sensory inspection first and then physical and chemical inspection. Grading, net weight, tolerance, packaging, marking and labeling should be inspected when the yellow peel is purchased at the place of origin as much as possible, and the physical, chemical and hygiene items should be completed in the laboratory. 5.1 Official Tibetan Index
5.1.1 Check the fruit shape, maturity, uniformity of clusters, color, branches, mechanical damage, pests and diseases, and foreign pollution by visual inspection. 5.1.2 Check the flavor by tasting.
5.1.3 If there are two or more unqualified items on the same fruit, only the one with the greater impact on quality shall be recorded. The percentage of unqualified fruit detected shall be calculated according to the fruit weight according to formula (1) according to the item in the record sheet, and calculated to one decimal place. 5. 1.4
P= 1 ×100
Where:
P————percentage of unqualified fruit, %;
——weight of unqualified fruit, in grams (g); w is the total fruit weight, in grams (g).
5.2 Determination of single fruit mass
5.2.1 Main equipment: a balance with a sensitivity of 0.1g and a maximum weighing capacity of 2000g. 5.2.2 Method: Randomly select 10 ears from the sample, with 10 fruit samples per ear, weigh the whole fruit mass, and calculate the single fruit mass. 5.3 Determination of edible rate

6 Inspection rules
6.1 Inspection categories
6.1.1 Type inspection
K-ml-m2-m×100
Type inspection is a comprehensive assessment of the product, that is, an inspection of all the requirements specified in this standard. Type inspection should be carried out in any of the following circumstances.
a) The national quality supervision agency or the competent department of the industry puts forward the type inspection requirements; b) The difference between the results of the two sampling inspections before and after is large;)
The production environment has changed significantly due to human or natural factors. 6.1.2 Delivery inspection
Before delivery of each batch of products, the producer shall conduct delivery inspection. Delivery inspection includes sensory, grading, marking, labeling and packaging. Delivery can only be carried out after passing the inspection and attaching a certificate of conformity.
6.2 Grouping
All yellow peels of the same origin, same variety, same grade and harvested in the same batch shall be regarded as one inspection batch. 6.3 Sampling
Perform in accordance with the provisions of GB/T8855.
6.4 Determination
6.4.1 Tolerance
Based on quality, in any batch of products, except for no rotten fruit, the following tolerances are allowed for superior and first-class products:4
a) Superior: No more than 5% of the fruit is allowed to fail to meet the requirements of this grade, but must meet the requirements of the first grade; b) First grade: No more than 10% of the fruit is allowed to fail to meet the requirements of this grade, but must meet the requirements of the second grade. 6.4.2 Determination
6.4.2.1 If any one of the hygiene indicators is unqualified, the whole batch of products shall be judged as unqualified products and shall not be retested. NY/T 692—2003
6.4.2.2 If the whole batch of products does not exceed the tolerance specified in a certain grade, it shall be judged as a certain grade of products. If it exceeds, it shall be judged according to the tolerance specified in the next grade until the grade is determined. If the "second grade" exceeds the tolerance range, it shall be judged as a substandard product. 6.5 Re-inspection
In addition to 6.4.2.1, if there is any objection to the inspection result, it is allowed to re-inspect with spare samples (if conditions permit, another sample can be drawn). The re-inspection is limited to one time and the re-inspection result is the final result. 7 Packaging, marking, labeling
7.1 Packaging
Packaging should be made of new, clean, non-toxic and odorless materials, and they should be of a quality that will not cause internal and external damage. In addition to meeting the above requirements, packaging containers should also meet the requirements of air permeability and strength, and be of appropriate and consistent size to ensure the handling, stacking, storage and sale of products. The type of container can be selected according to needs and local conditions. Generally, cartons, bamboo baskets and plastic boxes can be selected. The capacity of the container should not exceed 10 kg.
7.2 Marking and labeling
7.2.1 Marking shall be carried out in accordance with GB/T191. 7.2.2 Labeling shall be carried out in accordance with GB7718.
8 Purchase, storage and transportation
8.1 Storage
8.1.1 The storage site should be clean, cool and ventilated, with a relative humidity of not less than 70%, non-toxic, odorless, pollution-free, and equipped with sunscreen and rainproof facilities. 8.1.2 The interval between the fruit harvest and the storage warehouse (cold storage, ventilated warehouse, transportation vehicle, etc.) should be no more than 12 hours as much as possible, and no more than 24 hours at most. Products should be stacked according to grade and should not be mixed with toxic, odorous items or heavy metals. If the harvested fruit is to be transported, it should be placed in a cool and ventilated place with sunscreen and rainproof facilities, and the waiting period should be shortened as much as possible. 8.2 Transportation
