Using banana peel extract as an antioxidant in freshly squeezed orange juices and juices from concentrate was evaluated. Free radical scavenging capacity increased by adding banana peel extracts to both types of orange juice. In addition, remarkable increases in antioxidant capacity using 2,2'-azino-bis-(3-ethylbenzothiazoline)-6-sulfonic acid (ABTS) radical were observed when equal or greater than 5 mg of banana peel extract per ml of freshly squeezed juice was added. No clear effects were observed in the capacity to inhibit lipid peroxidation. Adding 5 mg banana peel extract per ml of orange juice did not substantially modify the physicochemical and sensory characteristics of either type of juice. However, undesirable changes in the sensory characteristics (in-mouth sensations and colour) were detected when equal or greater than 10 mg banana peel extract per ml of orange juice was added. These results confirm that banana peel is a promising natural additive that increases the capacity to scavenge free radicals of orange juice with acceptable sensory and physicochemical characteristics for the consumer.

<p style="text-align: justify;">Red wine produced from Listán Negro and Negramoll grapes from the Canary Islands (Spain) was firstly aged in new American and French (Allier) oak barrels in order to measure composition and sensory changes during 21 months. Aging resulted in an increase in titratable and volatile acidity and a decrease in ethanol concentration with a greater evaporation in the American oak samples. Initially, there was also an increase in color density due to the polymerization of anthocyanins. Extraction of total phenols was greater in the French barrels.</p>

<p style="text-align: justify;">This note presents the analysis of seventy-one red wines of the same vintage (90) from twenty different private wineries in the Tacoronte-Acentejo region, located on the northern slope of the island of Tenerife. This region has a basically Mediterranean climate, tempered by the mild, damp trade winds, and a volcanic soil, very rich in minerals and highly fertile.</p>
