Triple Advantages of Rice Freshness Testers：Efficiency, Accuracy, Convenience

Rice will gradually age during storage, leading to loss of nutrients, deterioration of taste, and even the production of harmful substances. The traditional freshness evaluation method relies on artificial sensory evaluation, which has problems such as strong subjectivity and inconsistent standards.

The rice freshness tester, based on the industry standard LS/T 6118-2017 "Determination and Discrimination of Rice Freshness in Grain and Oil Inspection", quantifies the freshness of rice through scientific methods, providing an objective quality evaluation basis for grain procurement, storage, processing, and sales.

Working principle of a rice freshness tester

1. Fundamentals of Scientific Principles

The working principle of the rice freshness tester is based on the quantitative detection of aldehydes and ketones produced during the aging process of rice. As the storage time prolongs, the fat in rice will gradually oxidize and decompose, producing a series of aldehydes and ketones. The content of these substances is negatively correlated with the freshness of rice.

2. The instrument testing process is as follows:

Rice samples to be tested will be husked and ground into third grade rice

Take 0.5-2g of rice sample and add a special freshness tester

Perform centrifugal treatment after oscillating and mixing

Detect the color change of the mixed solution after the reaction

Analyzing the degree of color change through a precision optical system

Calculate and display the freshness value (FD value, range 0-100 points) of the sample

Key Technology Analysis

The rice freshness tester adopts multiple advanced technologies to ensure the accuracy and reliability of the test results:

Precision optical detection system: using precision rotating detection device to ensure consistency of light source and eliminate detection deviation
