Comparison of suansun fermentation methods based on SBSE-GC-MS combined with SVM machine learning

The study highlights that natural water-sealed fermentation is the most effective method for enhancing flavor profiles, and that Weissella plays a significant role in the production of key flavor compounds, particularly p-cresol, which increased over 600 times in natural water-sealed fermentation. Direct fermentation significantly shortens the fermentation cycle, while natural water-sealed fermentation offers the best results in terms of flavor development.
