The aim of the work was to examine β-carotene as a synergist added in two doses to α and δ-tocopherol. As well as determine its antioxidant activity. The experiment was performed using pork lard as a triaciloglicerol substrate. It was found that tocopherol disintegration in lard depends on quantity of peroxide and it is faster as its concentration in substrate is lower and higher amount of β-carotene is added.
