### Qualitative Analysis of VOCs in Kiwiberry Cultivars  
The cv Geneva used in this study had fruit with green flesh and skin, while the fruit of cv Weiki was characterized by green flesh and a red blush. The tested cvs showed significant variation in the profile of the volatile organic compounds (VOCs). A total of 39 and 68 volatile organic compounds (VOCs) were detected in all the tested (untreated and HHP-treated) samples of cvs Geneva and Weiki, respectively (Tables 1 and 2). Most of the VOCs were linked with their aroma notes. Therefore, aroma descriptors for identified compounds were collected from the online databases perobase.com and pubchem.com (accessed on 1 August 2022). \begin{table}
