Glass, metal, cardboard, paper or polyethylene packagings with bee pollen shall be packed into dry, free form foreign smells tight board boxes in accordance with GOST 13358, GOST 13360. The bottom, the side boards of boxes, and the space be
11、tween packing units shall be stuffed with a dry material free from foreign smells (wooden chips, foam plastic, cardboard) so as to prevent the packages from moving within the box. -,-,- GOST 28887-90 p. 3 1.4. Marking 1.4.1. The marking shall be stamped or printed on packages or paper labels with sm
12、udge-proof paint in accordance with GOST 14192. The labels shall be stuck to containers and packing units. 2. ACCEPTANCE 2.1. Bee pollen shall be accepted in batches. Any quantity of bee pollen that is procured in one year, uniform against all the indicators, intended for simultaneous acceptance, an
13、d provided with one quality certificate, shall be considered as a batch. The following shall be indicated in the certificate: the document number; the year when the bee pollen was gathered by bees; the designation of basic plants giving pollen and nectar; the gross and net weights; the date of manuf
14、acturing and packing; the batch number and the amount of units in the batch; test results; the number of this Standard; a stamp of the manufacturer. 2.2. Where disputes arise over the evaluation of the pollen quality, repeated sampling and a test shall be carried out. The results of re-testing shall
15、 be assigned to the entire batch. 3. TEST METHODS 3.1. Sampling methods 3.1.1. 1 % (if the batch weight is below 100 kg) or 0.5% (if the batch weight exceeds 100 kg) of bee pollen shall be taken from different packing units of a batch by a grain probe so as to examine whether the bee pollen quality
16、complies with respective requirements of the Standard. The selected bee pollen shall be quartered to obtain an average sample 100 to 200 g in weight for carrying out tests. For this purpose, the selected bee pollen shall be formed into a leveled square layer at least 3 cm thick that shall be quarter
17、ed along its diagonals. Two opposite triangles shall be removed, and the two remaining ones shall be combined, and pollen shall be stirred. This operation shall be repeated until such a quantity of crude pollen remains that corresponds to the weight of an average sample. -,-,- p. 4 GOST 28887-90 3.1
18、.2. The average bee pollen sample shall be thoroughly stirred and divided into two parts. One part of bee pollen shall be used in testing, and the other one shall be placed into a dry, clean glass jar 50 to 100 cm3 in capacity in accordance with GOST 5717, closed with a lid or a ground stopper and p
19、araffined. A label shall be stuck on the jar, and the jar shall be stored for 3 months for tests, in case disputes between the customer and the supplier should arise. 3.2. The appearance and color of bee pollen shall be determined visually in natural daylight. The smell, taste, consistency, contamin
20、ation with mildew or moth larvae shall be determined organoleptically. 3.3. The contents of crude protein, crude ash, flavonoid compounds and toxic impurities, and the oxidizability factor shall be determined if disputes arise over the evaluation of the product quality. 3.4.

22、 than 0.01 g, and laid out on a clean paper sheet. Impurities shall be picked up by tweezers and weighed with a margin of error of no more than 0.01 g. 3.4.3. Processing of the results The mass fraction of mechanical impurities (X) in percent shall be calculated using the formula , 100 1 m m X = whe
23、re m is the weight of a beebread sample, in g; m1 is the weight of mechanical impurities, in g. The arithmetic mean of results of two independent tests, the permitted divergence between which shall not exceed 0.5 %, shall be considered to be the final test result. Bee pollen shall be poured into jar
