    Color, phenolics, and antioxidant activity of blackberry (Rubus glaucus Benth.), blueberry (Vaccinium floribundum Kunth.), and apple wines from Ecuador
    (Wiley, 2013) Ortiz, Jacqueline; Marín Arroyo, Remedios; Noriega Domínguez, María José; Navarro Huidobro, Montserrat; Arozarena Martinicorena, Íñigo; Tecnología de Alimentos; Elikagaien Teknologia
    Seventy wines were produced in Ecuador under different processing conditions with local fruits: Andean blackberries (Rubus glaucus Benth.) and blueberries (Vaccinium floribundum Kunth.) and Golden Reinette apples. Wines were evaluated for antioxidant activity (AA) using the radical scavenging capacity (DPPH) method, total phenolic content (TPC) using the Folin–Ciocalteu method, total monomeric anthocyanins (TMAs) using the pH differential test, and color parameters using VIS-spectrophotometry. For blackberry wines, ellagitannins and anthocyanins were also analyzed using high-performance liquid chromatography with diode-array detection (HPLC-DAD). Apples wines (n=40) hadthe lowest TPC (608±86 mg/L) and AA (2.1±0.3 mM Trolox). Blueberry wines (n=12) had high TPC (1086±194 mg/L) and moderate AA (5.4±0.8 mM) but very low TMA (8±3 mg/L), with a color evolved toward yellow and blue shades. Blackberry wines (n=10) had the highest TPC (1265±91 mg/L) and AA (12±1 mM). Ellagitannins were the major phenolics (1172±115 mg/L) and correlated well with AA (r=0.88). Within anthocyanins (TMA73±16 mg/L), cyanidin-3-rutinoside (62%) and cyanidin-3-glucoside (15%) were predominant. Wines obtained by cofermentation of apples and blackberries (n=8) showed intermediate characteristics (TPC 999±83 mg/L, AA 6.2±0.7 mM, TMA 35±22 mg/L) between the blackberry and blueberry wines. The results suggest that the Andean berries,particularly R. glaucus, are suitable raw materials to produce wines with anin vitroantioxidant capacity that is comparable to red grape wines.

    Effect of modified atmosphere packaging (MAP) in the antioxidant capacity of arazá (Eugenia stipitata McVaugh), naranjilla (Solanum quitoense Lam.), and tree tomato (Solanum betaceum Cav.) fruits from Ecuador
    (Wiley, 2020) Llerena Silva, Wilma Maribel; Samaniego, Iván Rodrigo; Navarro Huidobro, Montserrat; Ortiz, Jacqueline; Angós Iturgaiz, Ignacio; Agronomía, Biotecnología y Alimentación; Agronomia, Bioteknologia eta Elikadura
    This study aimed to determine the effects of the modified atmosphere packaging (MAP) in the antioxidant capacity (AC) of arazá (Eugenia stipitata McVaugh), naranjilla (Solanum quitoense Lam.), and tree tomato (Solanum betaceum Cav.). AC was evaluated by ABTS and DPPH methods. Fruits were cold stored using three MAPs (MAP 1:2.5%2.5% O2: 5.0% CO2); (MAP 2:2.5% O2: 2.5% CO2); and (MAP 3:80% O2: 10% CO2) for 1, 4, 7, and 10 days. ABTS showed the highest AC values with respect to DPPH. Arazá fruit AC was correlated with total flavonoids content (TFC) (r >.8360) and total polyphenols content (TPC) (r >.7252). Naranjilla fruit (r >.8188) and tree tomato 2.5% O2: 2.5% CO2 (r >.7365), TPC and TFC showed significant correlations with the DPPH. When using the canonical correlation analysis, it was observed that TPC is responsible for AC of the three fruits, showing strong correlations (.9716) with DPPH. Practical applications: The present study has as practical applications to provide knowledge on the cold storage of araza Eugenia stipitata McVaugh), naranjilla (Solanum quitoense Lam.), and tree tomato (Solanum betaceum Cav.) fruits. It also describes the effect of modified atmosphere packaging (MAP) on the antioxidant capacity of the three fruits studied. This study provides knowledge about biological properties of these fruits during cold storage with modified atmosphere.
