Large scale preparation, stress analysis, and storage of headspace volatile condensates from Jasminum sambac flowers

•Jasmine floral volatile condensate (FVC) was prepared on a large scale.•FVC had greatly enhanced jasmine floral character odor and similar odorant profile.•Indole, linalool, and methyl anthranilate were the most potent odorants in FVCs.•Suitable flower harvest times were decided based on flower and FVC odor similarity.•The FVC clarity and scent were better maintained at 4 °C than room temperature. In this study, a large-scale preparation of jasmine floral volatile condensate (FVC) was conducted using fresh flowers without any extraction solvent involvement. Condensate volatile profiles were compared to those of fresh flowers for their scent characteristics and ability to withstand manufacturing and storage. The FVC possessed a typical jasmine flower scent, a similar odor polygon shape and greatly enhanced odor intensity and character odorants linalool, indole, and methyl anthranilate. In late August and September in Fuzhou, China, the ratio of odor activity values for indole/linalool in FVCs was close to that of fresh flowers, indicating that these were suitable local harvest times for FVC preparation. Room temperature storage for 30 months dramatically reduced the abundance of potent odorants and FVC scent intensity, while cold temperature (4 °C) storage was able to maintain FVC clarity and scent intensity. Our findings should be helpful at improving FVC quantity, quality, and storage.
