    (Springer US, 2018) Idir, Lamia; Zouhir, Cherrared; Amir, Youcef
    Opuntia ficus indica fruits have been associated with health effects, due to their protective actions against oxidation. Nevertheless, few studies about processing of Opuntia fruits are available’; therefore, we studied the pulp characteristics and processing of a local variety, for producing beverage nectars. The pulp had an average pH of 5.64, 13.47 °Brix, with total sugars (106 g L−1), K (1180 mg L−1), 503.3 µg L−1 of β carotene, 120 mg L−1 of total phenolic compounds, 4.9 mg and 46.9 mg L−1 respectively for betacyanins and betaxanthins and 243.4 mg L−1 of vitamin C. The formulated nectars with 35% of pulp (N35) and 45% of pulp (N45) had respectively 14 and 15 °Brix. Minor components represent 1109 and 1112 mg L−1 of K for N35 and N45 respectively, β carotene (318.6 µg and 362.8 µg L−1), and vitamin C 227 and 231 mg L−1. We confirmed the stability and acceptability of these beverages after a month of storage, after stability and panel tests. Therefore, we suggest that the pulp processing can be used as a new form of agro industrial utilization of this underutilized fruit
