Edible oil GC fingerprint identification technology, is put forward under the premise of the initiative which is the requirement of the rapid development of China's modern economy as well as people lives'urgent need to protect the physical health of oil consumers.1. Research objectives(1) to research appraisal of detection technology of edible oil by gas chromatographic fingerprint, to set up a natural animal and plant oil fatty acid GC fingerprinting patterns and to offer methods for the edible oil's quality control and quality safety identification.(2) to research detection technology and application of edible oil by gas chromatographic fingerprint, to explore favorable analytic conditions and the impact of the main factors mediating detection of edible oils and fats by gas chromatography.(3) to research analysis method of edible oils and fats in the GC fingerprint, to adopt the application of edible oils and fats GC fingerprint identification security, to understand the importance of research on the oil gas chromatographic fingerprint detection technology.2. Research contentsEdible oil GC fingerprint identification technology is a very practical subject, the main contents are:(1) the study of edible oil extraction process and the methods of its fingerprint's establishment for the characteristics of standardized edible oil;(2) the analysis of the edible oil GC fingerprint;(3) the correlative study of the edible oil fingerprint;(4) the popularization and application of quality control for edible oil GC fingerprint technology.3.Reseach methodologyIn the study of the topic, adopt many methods combined, such as:sampling, statistics, survey, tracking, experience summary, etc. These methods also combine with listing and graphic representation to achieve the research goal effectively.4. Research results(1) It has identified and standardized the procedures of the characteristics of extract(2) It has obtained the fingerprint of the general extract of standardized samples;(3) It has completed the analysis of fingerprint;(4) It has obtained the composition information of general extract and ingredients of various fatty acid;(5) It has completed a correlative study of GC fingerprint for common standard of cooking oil, edible oil rancidity, adulteration of edible oil and illegal cooking oil as well as other oil;(6) It has proposed the establishment of chromatographic fingerprint library and the standard database model;4. Research conclusions (1)The findings established the procedures and methods of oil features extractive and GC fingerprint detection technology could be applied to deal with large quantities of edible oil samples.(2) The findings indicated that GC fingerprint detection technology could be adopted in instant quality inspection and the quality and quantity judgments of edible oil could depend on GC fingerprint detection technology.(3) The findings showed that GC fingerprint detection technology had a higher degree of reappearance and recurrence, which meant detection technology with a higher degree of reliability. This finding was very practical and the study of oil gas chromatographic fingerprint identification technology must have a far-reaching and significant importance.
