The differences in thiamine and riboflavin content between the cultivars investigated were 24% and 18% respectively.
Compared with the raw material, cumulative losses of thiamine and riboflavin resulting from technological and culinary
treatment and 12 months storage were 70-82% and 48-68% respectively for treatment I, 57-78% and 39-69% for treatment
II, and 78-87% and 54-77% for treatment III. The highest thiamine and riboflavin retention of all the cultivars examined,
both in frozen and canned products, were in products from Laponia cultivar
