Abstract

Uobičajeno je prihvaćeno da zelje potječe iz zemalja sjeverne Europe i Baltičke obale te Mediteranskog područja. Varaždinsko zelje je povrtna kultura dobivena od autohtone čuvane sorte varaždinski kupus (Brassica oleracea var. capitata f. alba), upisane u sortnu listu u Republici Hrvatskoj, a koja se proizvodi na tradicionalan način, na ograničenom zemljopisnom području Varaždinske županije u sustavu kontrole izvornosti, podrijetla i kvalitete. U ovom radu je analizirano deset uzoraka varaždinskog zelja s ciljem određivanja udjela suhe tvari, vitamina C i ukupnih ugljikohidrata. Udjeli vitamina C i ugljikohidrata su određeni spektrofotometrijski. Udio suhe tvari je bio u rasponu od 6,78 ± 0,23 do 9,74 ± 0,57 %. Udio vitamina C je bio u rasponu od 48,19 ± 2,81 do 83,81 ± 0,64 mg 100 g-1 svježe tvari, a udio ukupnih ugljikohidrata u rasponu od 36,99 ± 3,01 do 59,06 ± 2,80 mg g-1 svježe tvari.

Abstract (english)

It is commonly accepted that the origin of cabbage is the north european countries and the Baltic Sea coast and the Mediterranean region. Cabbage “Varaždinsko zelje” (Brassica oleracea var. capitata f. alba) is an authentic vegetable variety of Varaždin cabbage, registered in the list of varieties of Croatia, which is in Varaždin region, produced in the traditional way under authenticity, origin and quality control. In this study ten samples of Varaždin cabbage in order to determine the content of dry matter, vitamin C and total carbohydrates. Spectrophotometric method was used for determination of contents of vitamin C and total carbohydrates. Dry matter was in range from 6,78 ± 0,23 to 9,74 ± 0,57 %. Content of vitamin C in Varaždin cabbage was in range from 48,19 ± 2,81 to 83,81 ± 0,64 mg 100 g-1 of fresh weight, and total carbohydrates were in range from 36,99 ± 3,01 to 59,06 ± 2,80 mg g-1 of fresh weight.
