Sažetak
Shallots are a perennial plant from the Alliaceae family classified within the common onion under the name Allium cepa Aggregatum group. The term shallot is also used for diploid and triploid viviparous onions known as Allium × proliferum (Moench) Schrad and Allium × cornutum Clementi ex Vis. The nutritional composition of 34 shallot accessions was analysed. Shallot accessions belonging to the A.× cornutum and and A. × proliferum groups are characterized by high dry matter content (around 25%) of which a little less than 50% is of inulin-type sugars, polysaccharides considered an excellent prebiotic with beneficial effects on human health. On the other hand, accessions belonging to the A. cepa Aggregatum group have lower dry matter content and as a result lower pungency (measured as pyruvic acid content) making them more acceptable for fresh consumption by a broader range of consumers but at the same time abundant in phenolic compounds especially in quercetin and isorhamnetin glycosides. We also observed a greater biodiversity among accessions within the A. cepa Aggregatum group in all analysed physico-chemical parameters compared to the other shallot groups. The investigated shallot accessions have excellent in vitro antioxidant capacity as well as excellent nutritional properties.
