The parameters assessed were total phenols, antioxidant
activity, b-carotene, potassium content, color and sensory evaluation. Mild method caused lower color
differences than common method, when comparing the jams to raw carrots. Antioxidant activity, total
phenols and potassium content loss were also lower in mild method. Both methods improved b-carotene
retention in jams. Following sensory analysis, products obtained by mild method showed the best scores
for taste and overall acceptability, with the highest scores being registered for purple jam. In particular,
high correlations between antioxidant activity, total phenols and purple products (both raw products and
jams) were emphasized by principal component analysis. In conclusion, the mild method described in
this paper helps to preserve the overall quality of perishable vegetables, such as local carrots
