Abstract

Vrsta indijanska banana (Asimina triloba L.), još uvijek nekima nepoznata voćna vrsta, nova je voćarska kultura u uzgoju u Republici Hrvatskoj stoga na svega nekoliko lokacija postoje manje plantaţe ove vrste. Indijanska banana podrijetlom je iz Sjeverne Amerike gdje raste samoniklo. Za konzumaciju koriste se plodovi, a koji se odlikuju velikom energetskom vrijednošću, a sadrţe i znatne količine različitih vitamina, minerala i ostalih fitokemikalija vaţnih za ljudsko zdravlje. Cilj ovog rada bio je utvrditi nutritivni potencijal, sadrţaj bioaktivnih spojeva i antiokidacijski kapacitet plodova vrste Asimina triloba L. s različitih lokacija uzgoja na području Republike Hrvatske. Svi analizirani plodovi indijanske banane odlikuju se visokim sadrţajem suhe tvari (prosječene vrijednosti neovisno o lokaciji 23,76%) kao i visokim vrijednostima topljive suhe tvari, prosječne vrijednosti 20,11%. Prema analiziranim fizikalno-kemijskim parametrima plodovi indijanske banane mogu se smatrati nutritivno vrijednom sirovinom. TakoĎer, prema analiziranim bioaktivnim spojevima, plodovi ove vrste odlikuju se visokim sadrţajem vitamina C (prosječno 35,69 mg/100 svjeţe tvari), ukupnih fenola (prosječno 224,02 mg GAE/100 g svjeţe tvari) i β- karotena (prosječno 95,62 μg/100 g svjeţe tvari), a time i visokim vrijednostima antioksidacijskog kapaciteta (prosječno 2412,92 μmol TE/L). Valja naglasiti kako se plodovi indijanske banane značajno razlikuju u analiziranim fizikalno-kemijskim parametrima kako i u sastavu bioaktivih spojeva s obzirom na lokaciju uzgoja, a čime se moţe zaključiti kako abitoski čimbenici, odnosno specifični pedoklimatski uvjeti različitih dijelova Hrvatske značajno utječu sa nutritivni sastav plodova indijanske banane. TakoĎer, temeljem svih provedenih analiza nutritivnog sastava, moţe se zaključiti kako su sve istraţivane lokacije (kontinentalna i primorska Hrvatska) pogodne za uzgoj ove voćne vrste.

Abstract (english)

The paw-paw (Asimina triloba L.), a fruit species still unknown to some, is a new fruit species grown in the Republic of Croatia, so that there are small plantations of this species in only a few places. Paw-paw is native to North America, where it grows wild. The fruit used for consumption is characterized by high energy value and contains significant amounts of various vitamins, minerals and other phytochemicals important for human health. The aim of this study was to determine the nutritional potential, bioactive compounds content and antioxidant capacity of the fruits of the species Asimina triloba L. from different growing areas in the Republic of Croatia. All analyzed paw-paw fruits are characterized by high content of dry matter (average values regardless of location 23.76%) and high value of soluble solids (average value 20.11%). According to the analyzed physicochemical parameters, the fruits of paw-paw can be considered as a nutritionally valuable raw material. Also, according to the analyzed bioactive compounds, the fruits of this species are characterized by a high content of vitamin C (average 35.69 mg/100 g fresh weight), total phenols (average 224.02 mg GAE/100 g fresh weight) and β-carotene (average 95.62 μg/100 g fresh weight), and thus high values of antioxidant capacity (average 2412.92 μmol TE/L). It should be emphasized that papaya fruits differ significantly in the analyzed physicochemical parameters and in the content of bioactive compounds, taking into account the location of cultivation, which leads to the conclusion that abiotic factors or specific pedoclimatic conditions in different parts of Croatia significantly influence the nutritional composition of paw-paw fruits. On the basis of all the nutrient composition analyzes carried out, it can also be concluded that all the locations studied (continental and Croatian coastal areas) are suitable for growing this fruit species.
