Abstract—Many of the compounds present in potato are important because of their beneficial effects on health, therefore, are highly desirable in the human diet. The orange and yellow colour of the tuber flesh is due to carotenoids. The aim of this research was to determine the content of total phenolic content and carotenoids in relationship with the colour of organically and conventionally cultivated potato varieties before and after period of storage. In the research 31 potato samples of 12 potato varieties were analyzed on total carotenoid, total phenolic content and colour. Obtained results show that there was significant influence on carotenoid content between different cultivation environments (p<0.05) and between varieties (p<0.05). Total phenolic content significantly varies both per variety (p<0.001) and storage conditions (p<0.001).

Index Terms—Potato variety, total phenol content, carotenoids, organic, conventional.
