What are the items of food additive testing and where can it be done?

Food additives testing items.

In the "National Food Safety Standard for the Use of Food Additives" (GB 2760-2014), food additives refer to synthetic or natural substances added to food for the purpose of improving food quality, color, aroma and taste, as well as for the needs of preservative, preservation and processing technology. Food flavors, basic substances in gum-based confectionery, and processing aids for the food industry are also included. At present, there are more than 20 categories and nearly 1,000 kinds of food additives, and it can be said that the food industry is inseparable from food additives.

However, improper or excessive addition of food additives occurs from time to time, and non-edible substances are added, which seriously affects food safety.

In real production and use, people often confuse food additives with non-edible substances, and think that adding non-edible substances to food is also a problem of food additives, but this is not the same thing.

The testing of food additives generally needs to test the following aspects:

1.Preservative testing: mainly testing commonly used preservatives in food, such as sulfonate, nitrite, benzoic acid, potassium sorbate, etc.

2.Pigment testing: detection of artificial colors commonly used in food, such as dyes, pigments and dry pigments.

3.Acidulant testing: Detect acidulant components in food, such as citric acid, succinic acid, single starch sugar, etc.

4.Sweetener testing: Detect sweetener components in food, such as erythritol, aspartame, saccharin, sucrose, etc.

5.Flavoring agent testing: testing of commonly used flavoring agents in food, such as chicken essence, monosodium glutamate, soy sauce, Hong Kong soy sauce, etc.

6.Leavening agent testing: testing of leavening agents commonly used in food, such as gelatin, protein, baking powder, etc.

7.Tranquilizer testing: Detect stabilizer components in food, such as gelatin, ink, bird egg white, sodium carboxymethyl starch, etc.

8.Antioxidant testing: Detect antioxidant components in food, such as vitamin C, vitamin E, polyphenols, etc.

To sum up, the detection of additives in food involves different kinds of additives, and the detection methods are diverse. In addition, different countries and regions have different requirements for the amount of additives used, the type of use and the restrictions, etc., which need to be tested according to the food hygiene standards and regulations of the specific region.

The testing of food additives will generally be determined according to the food variety, and the product standards implemented by the food will have the amount of food additives that should be added, and then the amount of food additives will be tested according to the variety.

Food additive testing can not be done by itself, and it is necessary to go to the statutory third-party testing agency Guolian Quality Inspection for testing. The testing of food additives has a good effect on maintaining the qualification of food additives.

Generally, food additive testing can only be detected in the testing agency or the Quality Supervision Bureau, whether it is within the safety range, the country has unified norms and standards, you just need to find the testing agency to explain the situation.

If you go to a specialized testing institution, the general testing fee is about 1,000.

A rapid estimation method for aluminium content in foods containing aluminium baking powder.

If the baking powder packaging is marked with the amount of additives, if the customer uses the amount of aluminum in accordance with the marked amount of additives, not only the customer shall be liable, but also as a seller and manufacturer should bear the corresponding legal responsibility, in accordance with the national standard "compound leavening agent", the aluminum content of baking powder needs to be marked, so the customer uses the aluminum baking powder to cause the aluminum exceeding the responsibility only to bear their own, and the food and chemical stores, manufacturers are not related.

Generally, the aluminum content marked on the packaging bag containing aluminum baking powder is between, and the customer can multiply the actual amount used by the aluminum content marked on the packaging bag, which is generally the actual content of aluminum in food after multiplying by 100.

For example, if the aluminum content of baking powder is 4 and the actual amount added by the customer is 2, then the aluminum content in the food is about 800ppm, and the calculation formula is: 4 2 100 800ppm.

Food additives are chemical compounds or natural substances added to food to improve the color, aroma, taste and other qualities of food, as well as for the needs of preservative and processing technology.

Substances added to food for technical purposes in the manufacture, processing, adjustment, handling, packaging, transportation, and storage of food. Food additives, as auxiliary ingredients, can directly or indirectly become food ingredients, but cannot affect the characteristics of food, and are substances that do not contain contaminants and do not aim to improve food nutrition.

Quality Inspection Institute Quality Supervision Institute: Every province and municipality has, you can contact directly, these institutions are specialized in testing 2Food and Drug Administration:

Not all food additives can be measured, only some of them can be measured. 3.Third-party testing organization:

There are several testing institutions in China, and the production enterprises are still known, and they can contact them by themselves. 4.Foreign-funded testing institutions:

The advantage is that the content of the test is relatively extensive, and the disadvantage is that it is more expensive, so it is not recommended to choose.

Every province and municipality has it, just contact it directly, and these institutions are specialized in testingFood and Drug Administration: Not all food additives can be tested, only some can be measured.

3.Third-party testing institutions: There are several testing institutions in China, which are still known to Hushan production enterprises, and they can contact them by themselves.

4.Foreign defense of Chinese-funded testing institutions: the advantage is that the content of the test is more widely imitated, and the disadvantage is that it is more expensive, so it is not recommended to choose.

Pro, the content of food inspection is very rich, including the analysis of the nutritional composition of food products, the analysis of contaminants in food, the analysis of food auxiliary materials and food distress or additives, food sensory identification, etc

Hello dear, there are many kinds of detection methods for food additives, including the following: 1High Performance Liquid Chromatography (HPLC):

This method is currently one of the most widely used food additive detection methods, and its filial piety principle is to use high pressure to separate the compounds in the sample, and then detect the specific additive components through the detector. 2.Gas Chromatography (GC):

This method can be used to detect more volatile additives, such as fragrances, esters, etc. The principle of this method is to separate the compounds in the sample using a gaseous carrier gas and then detect the corresponding additive components by the detector. 3.

Mass spectrometry (MS): Mass spectrometry is a highly sensitive, highly selective detection method for the detection of very small samples and trace components. The principle of this method is to ionize the compound molecules in the sample and then use a mass spectrometer to measure the mass-to-charge ratio of the ions.

4.Infrared spectroscopy (FTIR): This method utilizes different absorption peaks to identify different components in a sample and is suitable for the detection of powder and solid samples.

In addition, there are a variety of detection methods such as electrochemical, radioisotope, fluorescence, etc., and the selection of the appropriate detection method depends on the specific sample properties and additive composition. Hope it helps.
