60Co-γ射线辐照对椪柑皮品质的影响

TS255; 为探究不同剂量60Co-γ射线辐照对椪柑皮品质的影响,采用紫外-可见分光光度计、高效液相色谱仪等对椪柑皮主要功能成分进行测定.同时,利用顶空固相微萃取结合气相色谱-质谱仪对其挥发性物质成分进行定性定量分析.结果表明:辐照对椪柑皮的主要功能成分产生影响,一定辐照剂量处理能够增加总酚、总黄酮、川陈皮素与橘皮素含量,降低橙皮苷、没食子酸和阿魏酸含量,但对咖啡酸和绿原酸影响不显著;辐照处理对椪柑皮香气成分影响显著,烯烃类香气物质占比、种类及含量减少,相反,醇类、酚酸类及醛酮类香气物质增加,辐照处理后椪柑皮新增51种香气物质,气味活性值显示芳樟醇、柠檬烯和正辛醛是辐照椪柑皮的关键香气物质....

Abstract_FL To investigate the effect of different doses of 60Co-γ ray irradiation on the quality of ponkan peels,the major functional components of irradiated ponkan peels were determined by ultraviolet-visible(UV-Vis)spectrophotometry and high performance liquid chromatography(HPLC).The volatile components were analyzed qualitatively and quantitatively using headspace-solid phase microextraction-gas chromatography-mass spectrometry(HS-SPME-GC-MS).The results showed that irradiation affected the major functional constituents of ponkan peels.Treatment with a certain dose of irradiation increased the contents of total phenol,total flavonoid,nobiletin and tangeretin while decreasing the contents of hesperidin,gallic acid and ferulic acid,but had no significant effect on caffeic acid or chlorogenic acid.The irradiation treatment had a significant effect on the aroma constituents of ponkan peels,resulting in a decrease in the percentage,type and content of olefinic substances and an increase in the contents of alcohols,phenolic acids and aldehydes and ketones.Totally 51 new aroma substances were formed after irradiation treatment,and the odor activity value(OAV)showed that linalool,limonene and n-octanal were the key aroma substances of irradiated ponkan peels,indicating that 60Co-γ ray treatment accelerated the aging of ponkan peels.In addition,principal component analysis(PCA)showed that the quality of ponkan peels varied with different irradiation doses,the highest overall evaluation score being observed for ponkan peels irradiated at 4 kGy.This study provides a reference for accelerating the aging of Pericarpium Citri Reticulatae as well as a basis for the development and utilization of Pericarpium Citri Reticulatae products.
