With the continuous improvement of living standards, consumers' demands for food quality are increasing day by day. As an important component of staple food, the freshness of rice not only directly affects the taste and flavor of rice, but also relates to its nutritional value and food safety. Traditional detection methods have limitations such as low efficiency and strong subjectivity, while an innovative technology based on luminol chemiluminescence is bringing revolutionary breakthroughs to this field.

1、 The limitations and breakthroughs of traditional detection methods

For a long time, the detection of rice freshness has mainly relied on sensory evaluation and analysis of basic physical and chemical indicators. Although these methods are easy to operate, they have obvious shortcomings: sensory evaluation is easily influenced by subjective factors, and different operators may come to completely different conclusions; However, physical and chemical indicators such as moisture content and fatty acid value require complex sample pretreatment and time-consuming analysis processes, which are difficult to meet the modern grain industry's demand for rapid and accurate detection.

2、 The principle of luminol chemiluminescence method

Luminol chemiluminescence method is based on a sophisticated biochemical reaction principle. Peroxidase is an enzyme widely present in plants, and its activity undergoes regular changes with the prolonged storage time of rice. Under alkaline conditions, peroxidase can catalyze the oxidation reaction between hydrogen peroxide and luminol, generating 3-amino-phthalates in an excited state. When this excited state molecule returns to its ground state, it will release photons and produce blue light.

3、 Advantages of Luminol over Traditional Methods

Compared to traditional methods for detecting the freshness of rice, luminol chemiluminescence technology demonstrates its unique advantages. Traditional methods such as sensory evaluation suffer from strong subjectivity and poor repeatability; However, the detection of physical and chemical indicators is often complex and time-consuming, making it difficult to meet the needs of large-scale and rapid detection. Luminol chemiluminescence technology solves these pain points with its high sensitivity, fast response, and easy operation. Moreover, the equipment required for this technology is relatively simple, suitable for promotion and application in different scenarios such as grain procurement points and warehousing enterprises, and has strong practicality and economy.
