Abstract   BACKGROUND: The distribution of bioactive compounds within a fruit is not homogenous. A better understanding of the developmental profile of the taste-related and bioactive compounds within different fruit tissues will be useful. OBJECTIVE: The aim of this study was to characterise the evolution of the taste-related and bioactive compounds in the internal and external tissues during stages of ripening strawberry fruits. METHODS: Taste-related compounds were analysed using refractometric and titrational methods. Phenolics was analysed using LC-MS. HPLC-UV was used to identify and quantify the levels of individual compounds. Antioxidant capacity and anthocyanins were determined photometrically. RESULTS: The perception of the taste could be attributed to the internal tissues. Regarding the bioactive compound contents, polyphenol compounds were present from the initial stage of fruit development. Among them, pelargonidin derivatives contributed to the antioxidant capacity only after the fruit had reached the 50%-red stage. They first accumulated in the external tissues and only later accumulated in the internal tissues. Ellagitannins were initially present in both tissues suggesting their antioxidant capacity contribution throughout the fruit ripening stages. CONCLUSIONS: This study demonstrated significant differences in the accumulation processes of bioactive compounds in the internal and the external layers of strawberry fruits.
