Abstract
AbstractBackgroundJabuticaba is a tasty Brazilian fruit that can be used in vinegar production. This study aimed to determine the phenolic, volatile, and sensory profiles; antioxidant activity; and chemical characteristics of vinegars produced with fruits, with and without the peel, of Myrciaria cauliflora (Mart.) O.Berg and Myrciaria jaboticaba (Vell.) Berg.ResultsFourteen phenolic compounds were identified and quantified, classified between phenolic acids and flavonoids, with emphasis on 3,4‐dihydroxybenzoic acid, chlorogenic acid, and sinapic acid. The highest antioxidant activity was found in M. jaboticaba vinegar, made with unpeeled fruits. For volatile compounds, 21 esters, 7 alcohols, 5 terpenes, 1 ketone, and 1 vinylarene were identified. Sensory analysis showed similarities in terms of taste and differences in terms of odor between Jabuticaba vinegars and commercial vinegars. The mineral content demonstrates the nutritional potential of vinegars in terms of macro and micronutrients, with a predominance of potassium and calcium. Phenolic compounds, acetic acid, and esters were the main chemical groups identified. Vinegars, in general, showed differences concerning the presence and absence of peels.ConclusionVinegars produced with different varieties of Jabuticabas can be a promising alternative for obtaining beverages with important compounds for human health, promoting local production, and adding value to regional products.
