方案详情

用紫外线在300-400nm波长下照射香蕉皮,会检测到在430nm有最高峰的蓝色荧光。随着香蕉成熟度的增加,其含糖量也增高,发出的荧光强度也随之增加。所以可将此作为评价香蕉成熟度的指标之一。 研究使用日立高新F-7000荧光分光光度计,利用超高速扫描速度特点,使得光谱分析更加方便和快捷。

Measurement of Banana (3D Fluorescence Spectra) |NTRODUCTION The fluorescence of banana peel was analyzed. When the surface of the peel was irradiated by ultraviolet ray at 300-400 nm, a blue fluorescence having a peak at 430 nm was observed. There has been a report that when a bananaripens, even more intense fluorescence is observed around the sugar spots and thus, the fluorescence can be usedas an index of the ripeness. When the excitation and fluorescence wavelengths are unknown, the 3D spectrum iseffective. F-7000 fluorophotometer, with the fastest scan speed for the instrument class, allows the high-throughput KEY WORDS Bio/Medical Science/Food/Pharmaceutical, Food, Food Chemistry,Banana, 3D Fluorescence Spectrum, 3D, FL, F-7000 Fluorophotometer (FL) Sheet No.FL090014-01A SAMPLE ACCESSORY SAMPLE NAME: Banana peel Solid sample holder(P/N:650-0161) INSTRUMENT CONDITIONS INSTRUMENT : F-7000 RESPONSE : Auto FULLSCALE : 180 EX BANDPASS :5nm EM FILTER : 310 DIVISION NUMBER :1 EM BANDPASS :5nm PHOTOMULTIPLIER :R3788 SCAN SPEED : 60000 nm/min PHOTOMULTIPLIER VOL.: 400V Measurement of Banana (Excitation Spectrum) Fluorophotometer (FL) INTRODUCTION The fluoresce of banana peel was analyzed.
