3.2. Antioxidant activity, total phenols, b-carotene and inorganic
cation content of raw carrots and jams
The antioxidant activity, total phenols, b-carotene and potassium
content of raw carrots and jams are shown in Fig. 2. Common
method caused a reduction in antioxidant activity in all jams (from
36% in purple jam to 92% in commercial jam) compared to rawroots
(Fig. 2A). By contrast, mild method did not affect antioxidant
