Can corn oil testing** be done? What are the corn oil testing items and standards? How much does corn oil heavy metal testing cost? How long does it take for a corn oil test report to come out? Foshan Huajin's third-party material testing laboratory can provide all kinds of corn oil testing services, including quality testing, composition testing, acid number, heavy metals, microorganisms, pesticide residue testing, RoHS testing, etc. As a third-party testing center, the institution has CMA, CNAS certification and testing qualifications, complete testing equipment, scientific and reliable data, and can issue a nationally recognized corn oil test report within 5-10 working days.
Corn oil, also known as corn oil and corn germ oil, is an oil extracted from corn germ. The fat content of corn germ is between 17% and 45%, which accounts for more than 80% of the total fat content of corn. The fatty acids in corn oil are characterized by an unsaturated fatty acid content of up to 80 to 85 percent. Corn oil is a cooking oil that is widely used in food cooking and industrial production, but it is known that some corn oil may have quality problems, so it is necessary to conduct routine inspection of corn oil. This article will introduce the methods of routine corn oil testing, as well as the testing of this service**.
First, the method of routine inspection of corn oil:
1.Appearance inspection: Appearance inspection is the first step of corn oil inspection, which mainly checks whether the corn oil is dirty, turbid, stratification, suspended solids or precipitation.
2.Odor detection: Odor testing is the second step of corn oil inspection, which mainly checks whether corn oil has peculiar smell, sour odor, mildew smell, rotten smell, etc.
3.Ion detection: Ion detection is mainly to detect the presence of copper, iron, potassium, sodium and other elements in corn oil. Any above par levels of any of these elements indicate the presence of certain contaminants in corn oil.
4.Acid value test: Acidity test can determine whether corn oil is sour or not. It can measure the amount of free acid in the oil. It must be used in conjunction with the total ester content determined by elemental analysis in order to assess the total stability of the oils and fats.
5.Peroxide value detection: Peroxide value detection can determine whether corn oil has been colored. This is a simple and convenient method for identifying the decomposition activity of the double-bond-peroxide group in the oil in question and the content of the decomposition products caused by excessive oxidation. Peroxides are considered indicators of specific lipid mass ratios based on their effect on oil quality.
6.Impurity and adulteration testing: Impurity and adulteration testing can detect whether corn oil has been adulterated with other oils, such as safflower oil or soybean oil, and whether there are impurities, such as pesticide residues or other environmental pollutants.
The above is the method of routine inspection of corn oil, through these tests, you can judge whether the quality of corn oil meets the standard.
2. What items are tested for corn oil:
Corn oil testing items include: odor, taste, transparency, color, moisture and volatiles, sensory testing, pesticide residue testing, heavy metal testing, additive testing, nutrition label testing, density testing, impurity testing, moisture testing, transparency testing, acid value testing, peroxide value testing, microbial testing, insoluble impurities, acid value, soap content, smoke point, freezing test, heating test, fatty acid composition, solvent residue, aflatoxin B1, benzo(a)pyrene, lead, total arsenic, TBHQ, BHA, BHT, dimethoate, bethion, diquat, livicarin, chlordane, flupimeethoxalin and high-efficiency flupyrethoxalin, etc.
3. How much can I do a corn oil test:
Depending on the testing method and the situation of the laboratory, the ** of corn oil test will also be different. Usually the corn oil test in the laboratory is about 500 yuan to 1000 yuan, and the specific ** also needs to be decided according to the specific situation and the charging standards of different laboratories.
4. Conclusion: In the case of modern food safety receiving more and more attention, it has become very important to check the quality of corn oil. Through routine corn oil inspection, the quality of corn oil can be effectively tested and our health can be guaranteed. At the same time, consumers need to be careful to choose formal laboratories to prevent counterfeit and shoddy services.
Corn oil testing and inspection process:
1. Fill in the application form: contact Huajin testing staff to confirm the testing standards and projects, and sign the power of attorney.
2. Arrange to send samples: send the samples by express or directly to our laboratory.
3. Product testing: After payment, the laboratory arranges testing and issues a draft report.
4. Confirm the draft report and issue a formal report.
5. Report bill delivery service, as well as report interpretation and after-sales service.
The above is the relevant introduction of Huajin Testing on corn oil testing services, more about corn oil testing costs, standards, projects, cycles and other issues can be consulted by ** engineer or call for consultation. (Test The testing cycle, method and steps are subject to the engineer, if the sample is special, you can communicate with the engineer about the particularity of the sample, and the institution can design a reasonable testing and analysis plan for you to save your time).
