Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 5502-2008 "Inspection of grain and oil processing precision test." This standard compared with GB/T 5502-2008 main changes are as follows. --- Adjust the scope of application; --- Increasing the normative references; --- Modify the terms and definitions; --- Increase the instrument-assisted detection method and instrument detection method of the principle description; --- Added Eosin Y-methylene blue stain preparation method; --- Remove the magenta carbonate solution staining; --- Remove Sudan-Ⅲ ethanol solution staining; --- Modify the sample observation method; --- Remove the direct comparison method; --- Increased instrument-assisted detection method; --- Increased instrument detection method; --- Deleted in addition to rice other rice processing accuracy test methods. This standard proposed by the State Food Administration. This standard by the National Cereals and Oils Standardization Technical Committee (SAC/TC270) centralized. This standard was drafted. Beijing Oriental Side Technology Development Center, Hubei Province, grain and oil quality supervision and inspection center, Liaoning Province, grain and oil inspection supervisor Institute. The main drafters of this standard. Yu Suping, high rock, Shi Cuixia, Xiong Ning, Cui Guohua, Liu Fangfang, Ni Shanshan, Min Guo Chun. This standard replaces the standards previously issued as follows. --- GB/T 5502-1985, GB/T 5502-2008. Inspection of grain and oil processing precision inspection

3 Terms and definitions

GB/T 1354 defined and the following terms and definitions apply to this document. 3.1 Image acquisition imageacquisition Gather samples of the image, and the image information into the system can identify the process of information. 3.2 Image analysis imageanalysis Using mathematical methods to collect the image information to determine the process of analysis.

4 principle

Dyeing. the use of rice cortex, embryo and endosperm Eosin Y-methylene blue staining group molecules with different affinity, rice cortex, embryo and embryo Milk showed blue-green and purple. Comparative observation method. the use of stained rice samples and stained rice processing precision comparison of standard samples, through the test to determine the test The kind of processing accuracy and standard sample processing degree of compliance. Instrument-assisted detection method. stained rice samples and stained rice processing standard samples by image analysis method For comparison, according to the degree of remaining cortex and embryo on rice grain surface, the processing precision of rice is artificially determined. Instrument detection method. the use of image acquisition and image analysis to detect staining of the rice sample peel degree, the instrument automatically determine the rice Precision. ......
