The objective of this study was to develop butter oil with added oregano and basil plant extracts at different concentrations (0.2%, 0.4% and 0.6%) and to evaluate the chemical, physical and sensory characteristics. butter oil samples with plant extracts obtained good purchase intention for all treatments, with the addition of 0.2% basil vegetable extract being preferred. For the minimum quality parameters, all samples were within the allowable legislation. The humidity values ranged from 0.010 to 0.044 g 100 g-1 and acidity from 0.035 to 0.082 g 100 g-1; the peroxide index was 0 g 100 g-1 and the ether extract was 99.86 g 100 g-1. Thirty fatty acids were identified in the butter oil by gas chromatography. It was concluded that the development of butter oil with the addition of oregano and basil plant extracts had good sensory acceptance, meeting the minimum quality parameters throughout the analysed useful life.
