Publication number: 20230271109Abstract: The present disclosure discloses a method for accurately separating and identifying an oxidized triglyceride in frying oil, and belongs to the technical field of detection. In the present disclosure, the structure of the oxidized triglyceride (ox-TG) in the frying oil is identified by mass spectrometry first. It is found that after frying is conducted for 24 h, the ox-TG mainly includes epoxy ox-TG, hydroxyl ox-TG, and aldehyde ox-TG. Thus, the three types of ox-TG are selected as a template molecule to synthesize a surface molecularly imprinted polymer (SMIPs). Then, a polymer completely matched with the ox-TG template molecule in action site and spatial configuration is synthesized, and the specific ox-TG can be separated by using the SMIPs. According to the present disclosure, OXTG-SMIPs prepared by a molecular imprinting technology has good specificity, stability, and affinity, and accurate separation of the ox-TG in the frying oil can be achieved.Type: ApplicationFiled: April 17, 2023Publication date: August 31, 2023Inventors: Yuanfa Liu, Xinyu Cao, Yongjiang Xu, Liyang Yuan, Yanpeng Du, Zhaojun Zheng

Patent number: 11733230Abstract: The disclosure discloses a method for quickly and accurately analyzing polyphenol content in rapeseed oil, and belongs to the field of analysis of natural compounds. The separation method of the disclosure uses acetonitrile-water as an extractant to extract polyphenols from the rapeseed oil, and cooperates with a C18 adsorbent for purification, and then performs separation and purification. Compared with the traditional liquid-liquid extraction and solid-phase extraction, the method has an average recovery rate of polyphenols in the rapeseed oil of 81.31% to 102.95%, and RSDs of 0.86% to 8.03%, and has higher accuracy and precision. The method of the disclosure not only uses less organic reagents and causes less environmental pollution, but also reduces matrix interference and improves purification efficiency through optimization of the adsorbent.Type: GrantFiled: December 31, 2020Date of Patent: August 22, 2023Assignee: JIANGNAN UNIVERSITYInventors: Yuanfa Liu, Junge Song, Yongjiang Xu, Zhaojun Zheng, Chen Cao, Yinghong Zhai

Patent number: 11319565Abstract: The disclosure discloses a method for preparing a lipoamino acid compound based on deep eutectic solvents, and belongs to the field of organic synthesis. The preparation method of the disclosure uses a fatty acid and an amino acid as substrates, uses a deep eutectic solvent as a medium, and directly and efficiently prepares a single-chain lipoamino acid surfactant under the catalysis of lipase CALB. Alternatively, Amano lipase M is used as a catalyst to efficiently catalyze the reaction of an amino acid containing a plurality of amino groups with a fatty acid to prepare a Gemini amino acid. The method of the disclosure does not need to undergo protection and deprotection of the amino acid, and does not involve commonly used fatty acid chlorides. Compared with the traditional chemical synthesis methods, the disclosure has the advantages of greenness, safety, high selectivity, high yield, etc., and has very important potential application value.Type: GrantFiled: December 31, 2020Date of Patent: May 3, 2022Assignee: Jiangnan UniversityInventors: Yuanfa Liu, Binbin Nian, Chen Cao, Zhaojun Zheng, Yongjiang Xu, Yinghong Zhai
