Abstract: 【Objective】 The technique of gas chromatography-ion mobility spectroscopy (GC-IMS) was used to test volatile organic compounds(VOCs) of Muscat Hamburg berry,the finding provided a scientific basis for rational application of silicon fertilization and the targeted regulation of quality Muscat Hamburg berry. 【Methods】 To explore the directional control effect of different dosage of silicone on rose fragrant fruit flavor material and conventional quality index. 【Results】 47 kinds of volatile organic compounds were detected in Muscat Hamburg berry, among which, 32 kinds were qualitatively, including 4 kinds of esters, aldehydes, alcohols and ketones. Compared with CK, when the silicon concentration was 200 times, the peak volume of butyl acetate increased by 56.28%; when 400 times, the peak volume of Methyl benzoate increased by 176.45%, and the peak volume of butyl acetate increased by 42.52% at 600 times. 2-pentylfuran, n-hexanol (dimer), n-hexanol, 3-methyl-3-buten-1-ol, ethyl acetate, ethyl propionate (dimer), 3-methylbutyl the peakvolume of aldehydes and other substances gradually decreased or even disappeared with the rising level of the silica concentration. 【Conclusion】 Its volatile organic compounds(VOCs) were similar to CK when the silicon concentration was 600 times, and the similarity was found between 400times and 200times. At 400 times Muscat Hamburg incense glucose content was the highest, which was17.04%, the total acid content was the least, 0.35%.
