Sumario:The effects of organic farming on antioxidant activity, CIE L*a*b* color, carotenoids composition, minerals contents, vitamin C and sensory quality of Orogrande mandarin juices were studied. Independent of the farming type, mandarin juices can be considered as good source of some important nutrients, such as potassium and antioxidant chemicals, for example, b-cryptoxanthin. Organic farming of mandarins resulted in juices with higher antioxidant activity, total carotenoids concentrations, minerals (Ca, K and Fe) contents, vitamin C content, more appealing and intense orange color and better sensory quality. For instance, organic Orogrande juice contained significantly (p<0.001) higher total carotenoids content (22.7±0.3 mg/L) than conventional juice (15.7±0.4 mg/L); a similar pattern was observed for the antioxidant activity, with values being 0.076±0.004 and 0.053±0.003mM Trolox m/L in organic and convectional juices, respectively. A trained panel stated that organic Orogrande juices had higher intensities of orange color, fresh mandarin and floral aromas than conventional juices.
