Problems solved by technology

[0004] The purpose of the present invention is to solve the problems that traditional sulfite detection methods require certain instruments and equipment and cannot realize rapid detection, and the existing liquid sulfite rapid detection kits are inconvenient in detection operation, easy to deteriorate during transportation, storage or use. The problem is to provide a tablet for rapid detection of sulfite in food, which can be directly applied to food extracts to achieve rapid semi-quantitative or qualitative detection of sulfite content. It is easy to operate, can quickly dissolve and react with sulfite , the formation of colored substances is convenient for visual inspection, it is not easy to deteriorate during transportation, storage or use, it is easy to store, has a long shelf life, low production cost, and can be produced on a large scale

Abstract

The invention discloses a quick detection troche for sulfite in food, aiming to solve the problems that the traditional sulfite detection method can not quickly detect because of requiring certain instrument equipment and the existing quick detection kit for liquid sulfite is inconvenient to detect, transport and store and has big possibility of deteriorating. The detection troche is composed of 9.7-19% of detection agent, 15-30% of adhesive, 42-60% of thinner, 1-4% of lubricant and 2-5% of disintegrating agent. The quick detection troche can be directly applied for quickly detecting sulfite content in the food extracting solution semiquantitatively or qualitatively, has the advantages of small possibility of deterioration in the process of transportation, storage or utilization, long quality guarantee period and low product cost, and is simple in operation and easy to store, can be quickly dissolved to react with sulfite, generates colorful substance which is easy for visual inspection and can be produced in a large scale.

Description

Technical field [0001] The invention relates to the field of fast detection of food safety, in particular to a fast detection tablet for sulfite in food. Background technique [0002] Sulfite is widely used in various processed or ready-to-eat foods because of its bleaching, decolorizing, anti-corrosion, preservation, and anti-oxidation effects. Most countries allow sulfite to be used as food additives in food. In the food industry, the main addition forms of sulfites are sodium bisulfite, sodium sulfite, sodium hyposulfite and sodium metabisulfite. These substances are present in the food as free or combined sulfite ions after interacting with the ingredients in the food. In addition, sulfur is also used as a bleaching fumigant in some food processing, leaving some free sulfur dioxide in the food. Since the 1980s, the safety of sulfite has attracted more and more attention. It is now generally believed that excessive intake of sulfite in the human body will have a damaging eff...
