    • The present invention provides methods of extracting antioxidant compositions from olive-based starting materials, including olives, olive pulps, olive oil, and wastewater from olive oil manufacturing. One method includes the steps of extracting the olives, olive pulp or olive oil with a polar aqueous solvent to form an aqueous phase containing antioxidant components, passing the aqueous phase through a solid matrix to trap the antioxidant components on the matrix, and washing the matrix with a polar organic solvent to yield a solution of the antioxidant composition in the polar organic solvent. Another method includes the steps passing the wastewater from olive oil production containing antioxidant components through a solid matrix to trap the antioxidant components on the matrix, and washing the matrix with a polar organic solvent to yield a solution of the antioxidant composition in the polar organic solvent. The present invention also provides antioxidant compositions and methods of increasing the antioxidant activity of a product using such compositions.
    • 本发明提供从橄榄基起始材料中提取抗氧化剂组合物的方法,包括橄榄油,橄榄油,橄榄油和来自橄榄油制造的废水。 一种方法包括以极性水性溶剂萃取橄榄,橄榄浆或橄榄油以形成含有抗氧化成分的水相,使水相通过固体基质以将抗氧化成分捕获到基质上并洗涤基质 与极性有机溶剂反应,得到抗氧化剂组合物在极性有机溶剂中的溶液。 另一种方法包括使含有抗氧化成分的橄榄油生产废水通过固体基质以将抗氧化成分捕获到基体上的步骤,并用极性有机溶剂洗涤基质以产生抗氧化剂组合物在极性有机溶剂中的溶液 。 本发明还提供使用这种组合物增加产品的抗氧化活性的抗氧化剂组合物和方法。
