Note: If the sample is darker in color after saponification, 50 ml of distilled water can be added before titration. The amount of water added for the blank test is the same. 2.7 Determination of arsenic (As) content
2.7.1 Instrumentation
According to the instrumentation diagram of the "Arsenic Salt Test Method" of the 1985 edition of the Chinese Pharmacopoeia 2.7.2 Reagents and solutions
Hydrochloric acid (GB622: 1:1 solution;
Magnesium oxide (HGB3114)
Magnesium nitrate (HG31077): 10% solution;
Potassium iodide (GB1271): 15% solution;
Stannofluoride (GB6.38): 40% solution, prepared according to GB603 "Chemical reagent preparation and product preparation method"; non-metallic zinc (HGB3073),
Lead acetate cotton: prepared according to GB603,
Mercuric bromide test paper: prepared according to GB603,
Arsenic standard solution (1mL contains 0.001mg arsenic): prepared according to GB602 "Chemical reagent impurity standard solution preparation method" and diluted 100 times.
2.7.3 Operation procedure
Weigh 1g of sample (accurate to 0.1g), place it in 50mL porcelain evaporator III, add 1g of magnesium oxide and 5raL of magnesium nitrate solution (take the same amount of magnesium oxide and magnesium nitrate solution as blank at the same time). After evaporating on a water bath, heat with a low fire to carbonize, and then burn at 500-600℃ until the ash is completely reduced. Cool, add a small amount of water, and then add hydrochloric acid solution to neutralize and dissolve the residue, add water to a total volume of 23mL, transfer to a conical flask, add 5mL hydrochloric acid, 5mL potassium iodide solution and 5 drops of stannous chloride solution, shake and let stand at room temperature for 10min, then add 2g of arsenic-free metal zinc, immediately install the glass tube with lead acetate cotton and mercuric bromide test paper, and place it in the dark at 25-30℃ for 1h. The color of the mercuric bromide test paper shall not be darker than the standard. The standard is 2ml of arsenic standard solution and the sample are treated in the same way at the same time. 2.8 Determination of heavy metal content (in terms of Pb) 2.8.1 Reagents and solutions
Glacial acetic acid (GB 675): 1N solution,
Saturated hydrogen sulfide water: see GB603, (prepare immediately before use), b.
Lead standard solution (1mL contains 0.01mg lead), see GB602, dilute 10 times after preparation. 2.8.2 Operating procedures
Take 1g of sample (accurate to 0.1g) and add 1mL sulfuric acid to moisten it, slowly burn until sulfuric acid vapor is completely removed, burn at 500-550℃ until it is completely ash, cool, add 2mL hydrochloric acid and 5mL water, evaporate to dryness in a boiling water bath, add 15mL water and 2mL acetic acid solution, dissolve with slight heat, transfer to a 50mL sodium colorimetric tube, add water to 25mL, add 10mL saturated hydrogen sulfide aqueous solution, shake well, and let it stand for 10min to produce color, which shall not be darker than the standard.
The standard is to take 1mL of standard lead solution and perform the same operation as the sample. 3 Inspection rules
3.1 Ginger oil (distilled) should be inspected by the technical inspection department of the manufacturer. The manufacturer should ensure that all products shipped out of the factory meet the requirements of this standard. Each batch of products shipped out of the factory should be accompanied by a quality certificate, including: manufacturer's name, product name, production date, batch number, net weight, product quality certificate that meets this standard and standard number. 3.2 The acceptance unit has the right to inspect whether the quality of the received products meets the requirements of this standard in accordance with the provisions of this standard. Each batch number 101
shall be inspected once, and no batch number shall be inspected separately. GB8318-87
3.3 Take two samples from each batch of packaging units with less than 100 units, and three samples from each batch with more than 100 units. When opening the package for sampling, check the appearance to see if there is no moisture or impurities, then shake it to mix it thoroughly, and then use a glass sampling tube to absorb 25-35mL of the sample. The total amount of the sample shall not be less than 60mL, inject it into the mixer and mix it evenly, and then put it into two clean, dry, brown glass bottles with frosted stoppers. The bottles are marked with: manufacturer name, product name, batch number, quantity and sampling date. One bottle is for inspection, and the other bottle is kept for future reference. 3.4 If one of the indicators in the acceptance results does not meet the requirements of this standard, the manufacturer can re-examine the samples from twice the amount of packaging together with the manufacturer. If the re-examination results still show unqualified indicators, the batch of products cannot be accepted. 3.5 When the supply and demand parties have objections to the product quality, they can resolve them by agreement or invite a third party to arbitrate. 4.1 Ginger oil (distilled) should be packed in tin or aluminum barrels. The outside of the barrel should be marked with: food additive product name, manufacturer name, trademark, batch number, net weight, tare weight, production date and this standard number. If the ordering unit has special requirements, it can make a separate agreement with the manufacturer. 4.2 Ginger oil (distilled) should be stored in a cool and dry warehouse, and must not be piled in the open air. It should be protected from the sun and rain during transportation. 4.3 If the specified transportation conditions are met, the packaging is intact and unsealed, the shelf life of ginger oil (distilled) is six months. Additional remarks:
This standard is proposed by the Ministry of Light Industry and the Ministry of Health of the People's Republic of China. This standard is under the jurisdiction of the Spice Industry Science Research Institute of the Ministry of Light Industry and the Food Hygiene Supervision and Inspection Institute of the Ministry of Health. This standard is drafted by the Spice Industry Science Research Institute of the Ministry of Light Industry and the Zhejiang Provincial Health and Epidemic Prevention Station. ::: This standard is formulated with reference to the EOA13 (American Essential Oil Association) standard. , the legal unit of specific gravity is changed to relative density: the determination method still adopts QB796 "Specific gravity determination method of spices standard test method".
