Preliminary characterization of morphological and sensorial profile of the fresh fig (Ficus carica L.) fruits obtained from four Croatian cultivars

Morphological and sensorial profile of fresh fruits of four Croatian fig cultivars ('Bjelica', 'Zamorcica', 'Saraguja' and 'Crnica') grown in the Istria region (Croatia) were obtained. Soluble solids, water and dry matter content in figs were also determined. Difference in soluble solids among cultivars was not detected, but 'Bjelica' had the highest water and the lowest total dry matter content. 'Crnica' and 'Zamorcica' had globose shape, different from 'Saraguja' (oblong) and 'Bjelica' (oblate). The highest weight of fruit had 'Saraguja' and 'Crnica', while the lowest 'Zamorcica'. 'Bjelica' had the largest ostiole width. 'Zamorcica' and 'Bjelica' had medium fruit cavity differentiated from other cultivars (small). All figs were easy to peel, except 'Zamorcica' fruits. During sensory analysis, appearance and texture of the exterior and interior, aroma, flavor, taste, aftertaste and ease of peeling were evaluated. Each investigated fig cultivar had characteristic appearance and flavor sensory profiles. Colors of the fruit skin and pulp were completely different among cultivars. The color of the pith was off-white in all cultivars, except in 'Bjelica' (yellow). The skin texture was similar for 'Bjelica' and 'Zamorcica' (hairy low, matte) and differed from 'Crnica' (smooth, glossy, waxy, powdery) and 'Saraguja' (smooth, matte). 'Crnica' had the highest bitterness, astringency, skin thickness and stickiness, while the lowest sweetness. 'Zamorcica' had the lowest pith firm and the highest seed crunchiness. The overall aroma intensity was high in all cultivars, except in 'Crnica' (medium). The other fruity aroma, with exception fig aroma, was different among cultivars. The position of the ostiole was open in 'Bjelica' and 'Saraguja', and closed in 'Zamorcica' and 'Crnica'. A further study regarding the level of maturity, harvesting year and locations on the sensory profiles of Croatian fig cultivars are needed.
