Summary The fermented vegetable is a long-history food, and the addition of probiotics in recent years has pushed it in a novel direction. This study explored the impact of a Direct-vat set starter (DVS), comprising Lactiplantibacillus plantarum MC14 and Leuconostoc mesenteroides , on pickled radish (PR). The addition of DVS triggered a rapid reduction in pH and titratable acidity, leading to lowered nitrite levels and increased viable count. Textural analysis showed that DVS increased the springiness and chewiness of PR by about 55.07% and 25.73%, respectively. Organic acid analysis unveiled eight compounds. The addition of probiotics did not significantly affect the antioxidant properties but was able to significantly enhance the XO inhibitory activity of PR. DVS decreased undesirable flavor compounds such as isothiocyanates and sulfides, while elevating esters, aldehydes, and acids. Our results suggested that DVS is a promising starter culture that can enhance the texture and flavor of fermented vegetables.
