The objective of this study was to analyse the role of package obtained from a natural biopolymer of Quercurs robur L incorporating natural antioxidant compounds found in roasted seeds of grapes to lipid oxidation of butter during storage. Also were determined the properties of film: solubility in water, determination of antioxidant activity and water sorption activity. Were formed two sets of butter samples packed in paper respectively in a biopolymer mixed with antioxidant. Samples were stored at a temperature of +6C for a period of fourty days. Frequently was determined the peroxide index. The values of peroxide index show the role of package obtained from starch and polyphenolics extract of roasted seeds of Vitis vinifera grapes on lipid found in butter.
