Abstract
Ziziphus jujuba is a plant growing wildly in Istria (Slovenia, Croatia). It is mostly known as an ornamental plant.
Fruits are used for nutritional purposes, mostly in their fresh form or dates like dried.
In our study, the nutritional and physico-chemical properties of riped Ziziphus jujuba fruits from Istria were determined including water content, fibres, proteins, sugars, total fat, soluble solids, vitamin C, organic acids, total phenols, ash, minerals and fatty acids in seeds.
Riped Ziziphus jujuba fruits contain 42.25% water and 44.0% soluble solids.
Mesocarp contains on dry matter basis 36.5.0% glucose, 33.4% fructose and 0.22% sucrose, 83.8 mg/100 g ascorbic acid and 39.4 mg/100 g dehydro ascorbic acid.
We have also find that mesocarp contains 1.1% proteins, 0.73% total phenols and 1.7% of ash, 12.4% of insoluble and 6.7% of soluble fibres.
Jujube seeds contain 2.5% total fat.
