Summary:

There is a growing interest in Corema album (L.) D. Don fruits due to the unique white colour, mildly acidic lemony flavour and health-promoting properties associated with its bioactive composition. This study performs a physical–chemical characterisation of cultivated C. album fruits from a multi-origin clonal field. The field comprises ten wild populations with distinct geographical origins, grown under the same edaphoclimatic conditions. We analysed fruits CIELab colour parameters, texture profile (TPA), pH, acidity (TA, g.100 mL⁻¹), soluble solids content (SSC, %) and total phenolic content (TPC, mg CAE.100 g⁻¹). Our results showed differences between fruits physical–chemical attributes. Variation patterns in fruits SSC and hardness suggest that the differences might be related to the original geographical location of the populations. The determined TPC levels in all samples were very encouraging at a bioactive level, ranging from 185.3 to 355.6 mg CAE.100 g⁻¹. Fruits from Mira and Pego populations stood out from the ten geographical provenances. Mira fruit samples had higher sweetness and lower acidity, while the Pego ones had firmer fruits and higher phenolic content. The multi-origin clonal field allowed us to offer an interesting scientific comparative background, highlighting the large potential of these berries for introduction in the commercial market. Not only our results support the potential of white crowberry as a new crop; the detected differences also indicate a hidden capacity for small fruit market diversification.
