Mangoes (Mangifera indica L.) are popular seasonal fruit in Reunion Island and are regarded as a good source of dietary antioxidants, such as ascorbic acid, carotenoids, and mangiferin, and flavonoids (Ma et al., 2011). Mango pulps contains gallic acid, chlorogenic acid, vanillic acid and protocatechuic acid and gallic acid has been described as the predominant phenolic compound (Palafox-Carlos et al., 2012). The total phenolic content is higher than the total carotenoids in mango fruit (Fratianni et al., 2020) and these phenolic compounds and antioxidants could extend health benefits to consumers (Palafox-Carlos et al., 2012). Most mangoes are eaten as whole fruit, but oversupplies and their highly perishable nature (Ntsoane et al., 2019) force it to be processed to provide consumers with longer lasting products. Fermentation was practiced as a method of food preservation worldwide for centuries. Therefore, fermentation is an effective method for preserving the fruit (Coulibaly et al., 2020) to increase its availability during the off-season. Also, lactic acid bacteria (LAB) fermentation helps to maintains safety, improves nutritional and sensorial properties of food (Fessard et al., 2017).However, spontaneous fermentation could make the fermentation process to proceed at a slow rate or total cessation of the process.Un-controlled fermentation allows the growth of microbial contaminants which produces undesirable metabolites that are hazardous to
