Maleic hydrazide testing: maleic hydrazide, humus and other fruit and vegetable preservatives testing

2025-08-23


With the improvement of living standards, consumers' demand for fresh fruits and vegetables is growing day by day. In order to prolong the shelf life of fruits and vegetables and maintain their good commercial properties, preservatives have been widely used in the production and circulation of fruits and vegetables. However, if the preservatives are used improperly or the residues exceed the standard, they may pose a potential threat to human health. Among them, maleic hydrazide and pyrexine are two common chemicals in fruit and vegetable preservation, and their effective detection is an important part of ensuring food safety.

Maleic hydrazide is often used as a plant growth regulator and preservative, especially in the storage and preservation of high-starch vegetables such as potatoes and root vegetables such as onions. It can effectively inhibit the germination of tubers, bulbs, etc., and prolong the preservation time. Pylorum is a broad-spectrum fungicide. It is mainly used to control fungal diseases such as botrytis cinerea in the preservation of fruits and vegetables, thereby reducing rot and maintaining the quality of fruits and vegetables. These two substances can play a positive role under the premise of reasonable use, but once the residue exceeds the national standard, long-term intake may have adverse effects on human health. Therefore, the detection of the residue of maleic hydrazide and pylorum in fruits and vegetables is crucial.

The detection of preservatives such as maleic hydrazide and putrefaction in fruits and vegetables is a necessary measure to ensure food safety and protect public health. Through scientific and accurate testing, unqualified products can be detected and controlled in time to enter the market, and food safety risks can be effectively prevented. At the same time, it also helps to standardize the behavior of fruit and vegetable production, processing and operation enterprises, and promote the healthy and sustainable development of the fruit and vegetable industry.

In terms of detection technology, there are currently a variety of detection methods for preservatives such as maleic hydrazide and putrefaction, including instrumental analysis methods such as high-performance liquid chromatography, gas chromatography-mass spectrometry, and rapid detection methods. Instrumental analysis has the advantages of high accuracy and good sensitivity, but it is usually complicated and time-consuming, and requires professional laboratories and personnel. Rapid detection methods, such as colloidal gold immunochromatography, are easy to operate, fast and efficient, and relatively low cost. They play an increasingly important role in grassroots supervision, enterprise self-inspection, and on-site rapid screening, which can meet the needs of rapid preliminary screening of large quantities of samples. As a professional food safety rapid detection reagent manufacturer, Wuhan Yupinyan Bio is committed to providing reliable solutions for the detection of fruit and vegetable preservative residues. The relevant rapid detection reagents developed and produced by the company are designed to help users achieve rapid qualitative or quantitative detection of maleic hydrazide, humorimide and other targets, and provide strong technical support for food safety supervision.

To sum up, preservatives such as maleic hydrazide and humorimide play an important role in the preservation of fruits and vegetables, but strict control of their residues is an important part of food safety work. Through the use of appropriate detection methods, such as the use of rapid detection reagents provided by Wuhan Yupinyan Biology and other enterprises, the efficient monitoring of these preservative residues can be realized, so as to better protect the "safety on the tip of the tongue" of consumers and promote the green and healthy development of the fruit and vegetable industry.
