SummaryThe presence of betalain pigments in fruits ofOpuntia stricta, Opuntia undulata andOpuntia ficus-indica has been studied. Cultivars of deep red-purple colour, with high betacyanin content, were choosen for this investigation. The total betacyanin content was estimated spectrophotometrically E1cm1%=1120) and the results obtained indicated a higher betacyanin content inO. stricta (70 mg · 100 g−1 fresh fruit), than inO. undulata andO. ficus-indica (14–19 mg · 100 g−1 fresh fruit… CONTINUE READING
