Assessment of chemical composition of blackberries and mulberries from Covilhã region, Portugal

Year: 2024
Type: article
Abstract: Berries have gained popularity recently due to the health benefits associated with their bioactive compounds. This study aimed to analyze the physicochemical characteristics, color, phytochemicals content and mineral content of three common berries, two types of blackberries (Rubus fruticosus and R. ulmifolius) and one mulberry (Morus nigra), collected in the Covilhã region, Portugal. R. fruticosus presented the greatest length, weight, moisture, firmness and darker color, while R. ulmifolius showed the greatest width. On the other hand, M. nigra showed the highest ash content (2.49±0.40%). A total of 20 phenolics were identified by HPLC-DAD–ESI/MSn and quantified by HPLC-DAD. Using ICP-MS and flame atomic absorption spectrometry, 13 essential and 14 non-essential elements were quantified. Additionally, 68 volatiles were detected using HS-SPME/GC-MS. Our results show that these berries contain a high concentration of high-value bioactive compounds, significantly influencing their nutritional value, aroma and appeal to consumers.
