Abstract
This article presents an analysis of the impact of blanching and Ginkgo biloba extract (GBE) on the volatile organic compounds (VOCs) in Cantonese bacon using gas chromatography-ion mobility spectrometry (GC-IMS). The study aims to investigate how different processing techniques influence the composition of volatile compounds in meat products, thereby contributing to the understanding of flavour release patterns.The experiment involved dividing pork belly into six groups: conventional (C), heat treatment (H, 50 °C, 15 s), high-temperature treatment (S, 80 °C, 5 s), conventional treatment with GBE (CG, 0.5% GBE), heat composite treatment with GBE (HG, 50 °C, 15 s, 0.5% GBE), and high-temperature heat composite treatment with GBE (SG, 80 °C, 15 s, 0.5% GBE). The researchers identified a total of 36 compounds in the GC-IMS spectrum. The results showed that the ethanol content decreased in the H group samples after blanching treatment, while it increased in the S group samples. The CG, H, HG, and SG groups exhibited more significant changes compared to the C group. The H group had the highest number of VOCs among all the groups. Additionally, the flavour of the H, CG, and HG group products was notably enhanced.In conclusion, GC-IMS allows for real-time visual analysis of VOCs, and both blanching treatment and the addition of GBE significantly affect the composition of VOCs in the samples.
