Our team has more than 20 people, including 2 associate professors, 1 lecturer, 16 graduate students and 1 foreign student. We have received 5 National Natural Science Foundation of China Projects, 1 National Supporting of China Project, 1Natural Science Foundation of Tianjin Project and 2 Postdoctoral Science Funds, and also published more than 40 SCI papers, obtained 5 national patents. Heads of group went to Cornell University as visiting scholars, and established better relationship with the research of plant senescence and transcriptional factors. The main researches of our group are network of postharvest metabolism of fruits and vegetables, biological technology, storage and preservation and so on. The main research contents include function of tomato transcriptional factor (NAC); metabolism pathways and regulation mechanism of sugar, organic acids and flavor components of postharvest pears; isolation and function of asparagus oligosaccharide, antioxidant mechanism of asparagus; efficacy analysis of chickpea peptides; nutrient function and storage preservation of jujube, reddening mechanism of jujube; functional components and analysis of blueberry; use of calcium chloride, pulullan polysaccharide, natamycin and composite coating technology on fresh-keeping
