1980 "Sampling Method for Fresh Fruits and Vegetables". This standard applies to the sampling of fresh fruits and vegetables. In some cases, it can be implemented according to the sampling method specified in the signed contract. 2 Reference Standards
GB8854-88 Name of Vegetables
GB5009.1-85 General Rules for Food Hygiene Inspection Methods (Physical and Chemical Parts) 3 Explanation of Terms for Sampling Procedures
3.1 Contract Goods: Goods shipped or received at one time, the quantity of which is based on the specified contract or freight list. It can consist of one or more batches of goods.
3.2 Batch goods: goods with a certain quantity, the quality must be uniform (same variety or type, same maturity, same packaging, etc.). It belongs to a batch of contract goods, and can be used to evaluate the quality of contract goods. 3.3 Spot inspection goods: a small amount of goods taken from a location in the batch of goods. Multiple spot inspection goods should be sampled from different locations in the batch of goods.
3.4 Mixed sample: if conditions permit, samples are taken from a specific batch, mixed, and mixed to obtain a mixed sample. 3.5 Reduced sample: a sample representative of the batch of goods is obtained by reducing the mixed sample. 3.6 Laboratory sample: a laboratory sample is obtained from a reduced sample. 4 General requirements for sampling
4.1 Sampling should be carried out after consensus between the trading parties, or by personnel sent by government testing agencies. 4.2 The inspected goods should be confirmed before sampling. 4.3 The sampling tools and containers should be kept clean, dry, and free of odor. The sampling process should not be polluted by rain, dust, and other environmental factors. 4.4 Regardless of whether the collected samples are for routine on-site identification or sent to the laboratory for quality identification, random sampling is generally required. In some special cases, for example, in order to identify other varieties or any type of mixture, selective sampling is allowed. Before sampling, the purpose of sampling must be clear, that is, the nature of sample identification must be clarified. 4.5 The collected cargo samples should be able to fully represent all the characteristics of the batch of goods. The damaged parts (boxes, bags) are removed from the samples, and samples of damaged and undamaged parts are collected separately. 4.6 After the sampling is completed, the sampling report must be filled out immediately. 5 Sampling method
5.1 Sampling preparation for bulk goods
Batch goods sampling requires timely, and each batch of goods must be sampled separately. If damage occurs during transportation, the damaged parts (boxes, bags, etc.) must be isolated and a separate sample taken from the intact parts. Similarly, if the goods are considered uneven, the normal parts should be separated and sampled from each batch for identification unless otherwise agreed by the trading parties. 5.2 Sampling preparation for random inspection of goods
Random sampling of random inspection goods should be carried out from different locations of the batch of goods. 5.2.1 Packaged products
In the case of packaged products (wooden boxes, cartons, bags, etc.), random sampling shall be carried out in accordance with Table 1. Table 1 Number of samples of goods for random inspection
Number of similar goods in bulk
101~300
301~500
501~1000
5.2.2 Bulk products
Number of samples of goods for random inspection
15 (minimum)
According to the total amount, at least 5 samples of goods for random inspection shall be taken for each batch of goods. In the case of large individual vegetables or fruits (greater than 2kg/piece), the random inspection goods shall consist of at least 5 individuals. The sampling quantity of random inspection goods shall be sampled according to Table 2. Table 2 Sampling quantity of random inspection goods
Weight of bulk goods (kg) or number of pieces
201~500
501～1000
1001~5000
5.3 Preparation of reduced samples
Mix, reduce, prepare reduced samples, total weight of random inspection goods (kg) or total number of pieces
100 (minimum)
For mixed samples or reduced samples, sampling and inspection should be carried out on site. In order to avoid changes in the inspected properties, the inspection work should be completed as soon as possible after sampling.
5.4 Number of laboratory samples
The number of laboratory samples should be in accordance with the contract requirements, or three times the number of samples required for the inspection items. One for inspection, one for re-inspection, and one for reference. The minimum sampling quantity is shown in Table 3. 109
GB 8855---88

Packaging and handling of laboratory samples
6.1 Packaging
Laboratory samples that cannot be tested on site should be packaged and sealed to ensure the integrity of the samples. 6.2 Marking
Sampling quantity
5 individuals
10 individuals
Samples sent to the laboratory for testing must be well marked. The markings should be clear and firm. The label content should include the following items: a.
Product name, type, variety, quality grade; name of the consignor;
Sampling location,
Sampling time;
Identification mark or batch number (bulk goods or samples must have shipping records, vehicle numbers, and shipping warehouses); sampling report number;
Name and signature of the sampler;
Required inspection items:
Sample receiving unit, name of the sampler.
Shipping and storage
Packaged samples must ensure that the products do not deteriorate and be transported to the destination for inspection as soon as possible. Sampling report
The numbered sampling report should be attached to the sample packaging container or transported with the sample. The sampling report should include the following items: a.
Product name, type, variety, quality grade; consignee;
Delivery address, unit;
Shipping address, unit, consignor's name, consignment date; Goods storage location, continuous storage time, conditions, transportation method (vehicle type, number); required sampling date and time;
Sampling date and time;
Climate conditions at the time of sampling (such as temperature, etc.); i.
