[EN] Consumer interest in the use of natural ingredients is creating a growing trend in the food industry, leading to
research into the development of natural products such as colorants, antimicrobials and antioxidant compounds.
This work involves an extensive morphological (using physico-chemical assays), chemical (antioxidant activity
assays) and microbiological (Gram-positive and negative strains) characterization of prickly peras (Opuntia ficusindica
(OFI) var. sanguigna, gialla and Opuntia engelmannii) fruits. Through chromatographic assays, these
species have shown interesting contents of hydrophilic (sugars, organic acids and betalains) and lipophilic
(tocopherols and fatty acids) compounds. While Opuntia engelmannii exhibited higher content of betacyanins and
mucilage, OFI varieties sanguigna and gialla displayed greater organic acid content. The sanguigna variety also
showed the highest ¿-tocopherol content. All this compounds could be the responsible of enhancing the
bioactivity of this variety, which can be observed in its antimicrobial potential, tested in the studied strains too.
Results revealed that Opuntia spp. could be used as a nutraceutical and/or food additive, maintaining and
promoting health and life quality.[-]
