315 "Earthpit pickled Chinese cabbage" on the list - Taiwei Food Additive Detection Scheme

On Consumer Day 315, black heart pickled Chinese cabbage was exposed. In order to make "black heart pickled Chinese cabbage" more appetizing, excessive food additives were added in the production process. Reasonable food additives can extend the shelf life of food and maintain its flavor, while excessive consumption of food additives can pose a threat to human health.

Food safety is crucialThe major basic livelihood issues concerning people's health cannot be taken lightly.

Taiwei Technology is willing to contribute to promoting the development of food safety and health.

The production of black heart pickled Chinese cabbage uses color fixative sodium metabisulfite, sulfur dioxide, and preservative dehydroacetic acid

Sodium metabisulfite detection

Difficulty: Sodium metabisulfite is prone to decomposition, which does not mean there is no detection method.

This method uses ion chromatography,The AS11-HC chromatographic column, hydroxide system, and isocratic elution can complete the separation and detection of SO3 and SO4 within 30 minutes. Under alkaline conditions, the tested samples of sulfite, bisulfite, and pyrosulfite all exist in the form of SO3. The separation degree of O3 and SO4 is 2.97, the correlation coefficient of SO3 standard curve is 0.999, the detection limit of SO3 is 0.05ppm, and the recovery rate is above 90%. The detection results are accurate and reliable, and the method has strong applicability.

Dehydroacetic acid detection

Difficulty: Sodium saccharin interferes with the peak of dehydroacetic acid, resulting in inaccurate detection data.

Sulfur dioxide (sulfite) detection

Difficulty: The method for detecting sulfite in food is ion chromatography, which is prone to interference and requires optimization of pre-treatment methods and separation conditions.

Note: Adding a certain amount of food additives within a certain range is explicitly stipulated and allowed by national standards, and there is no need to panic.315 exposed unreasonable phenomena such as illegal and excessive additions.

Food safety has always been a topic closely related to our lives.
