Cold‐pressed Japanese quince (Chaenomeles japonica (Thunb.) Lindl. ex Spach) seed oil as a rich source of α‐tocopherol, carotenoids and phenolics: A comparison of the composition and antioxidant activity with nine other plant oils

摘要: New cold-pressed oil recovered from seeds of Japanese quince (Chaenomeles japonica (Thunb.) Lindl. ex Spach, family: Rosaceae), obtained as a by-product fruit processing, was characterized and compared with nine well-known oils. The seed had the highest amounts tocopherols, β-carotene, total phenolic compounds (726.20; 10.77 64.03 mg/kg, respectively) lowest amount chlorophyll (0.12 mg/kg) peroxide value (0.59 mEq O2/kg) to sesame, poppy, peanut, flaxseed, pumpkin, sunflower, almond, hazelnut, walnut A correlation found between contents tocochromanols, compounds, radical-scavenging capacity oils (0.94, 0.68, 0.63, respectively), also CIE a* coordinate (0.80) β-carotene b* (0.47). In oil, 13 fatty acids were identified three predominating: palmitic acid (10.07%), oleic (34.55%), linoleic (52.35%). consumer acceptance noted for hazelnut oils, while it poppy flaxseed Amygdalin not detected in oil. Practical applications: This study demonstrated that is richer source nutritional bio-components than other commercial positive results sensory evaluation absence amygdalin indicates its potential future use food. Moreover, by-products industry; therefore, utilization obtaining new, healthy products ensures environmental sustainability more effective harvested plant material.
