Rice Quality Identification Standards and the Role of Rice Appearance Quality Detectors

The appearance quality of rice is an important and intuitive indicator for assessing rice quality. It is not only the first characteristic consumers notice when purchasing but is also often closely related to the taste, nutritional value, and storage performance of the rice. Rice quality identification standards encompass multiple aspects. The LANENDE Rice Appearance Quality Detector, as an advanced testing instrument, plays a significant role in rice quality inspection. Below is a detailed elaboration on rice quality identification standards and how the Lainder detector assists in this process:

I. Rice Quality Identification Standards

Broken Rice Rate: Broken rice refers to grains shorter than 3/4 the average length of the whole rice kernels in the same batch. High-quality rice has fewer broken grains, as excessive broken rice affects the appearance and texture of cooked rice.

Chalkiness Degree: Chalkiness is a key indicator of rice quality. Rice with fewer chalky grains and smaller chalky areas is considered higher quality.

Odor: High-quality rice typically has a natural, fragrant aroma. The presence of off-odors, mustiness, sourness, or other pungent smells may indicate spoilage.

Impurities: Impurities refer to foreign matter other than rice kernels, such as bran, paddy grains, weed seeds, sand, stones, or soil. High-quality rice should be clean, free of impurities, and not contain rice grains significantly different from the batch.

Appearance and Morphology: High-quality rice grains are typically whole, plump, and uniform in color.

Taste Score Value: As determined by professional laboratory testing, high-quality rice generally has a higher taste score, indicating better palatability.

Furthermore, the Chinese National Standard GB/T 1354-2018 "Rice" classifies high-quality rice into Premium Grade 1, Premium Grade 2, and Premium Grade 3, specifying 11 evaluation indicators including broken rice, milling degree, chalkiness degree, and taste score value.

II. How the Lainder Rice Appearance Quality Detector Assists in Rice Quality Inspection

Multi-Parameter Measurement: The Lainder detector can automatically measure various parameters for each rice grain, including area, length, width, length-to-width ratio, diameter, and roundness, providing comprehensive appearance quality data.

Automated Analysis: The instrument features automated analysis functions, capable of automatically measuring and analyzing indicators such as chalkiness degree/rate, broken rice rate, small broken rice rate, head rice count, and head rice yield, significantly improving inspection efficiency.

High-Precision Measurement: Utilizing high-resolution scanner imaging, the instrument offers minimal measurement error and high reproducibility, ensuring the accuracy of test results.

Compliance with National Standards: The detection indicators of the Lainder detector correspond with those in the national standard, ensuring the compliance of the inspection results.

Intelligent Operation: The instrument possesses automatic learning and identification capabilities. It can automatically separate adhered rice grains or seeds and perform automatic classification analysis. Additionally, it features cloud platform support, allowing analysis data to be saved to the cloud for convenient access anytime, anywhere.

Versatile Applications: This instrument can be used not only for the appearance quality inspection of various types of rice (e.g., milled rice, brown rice, glutinous rice) but also for samples like black rice, demonstrating broad application prospects.

In summary, rice quality identification standards involve multiple aspects. The Lainder Rice Appearance Quality Detector, as an advanced testing instrument, plays a vital role in rice quality inspection. By using this instrument, rapid and accurate detection of rice appearance quality can be achieved, providing strong support for the control and enhancement of rice quality.
