Designation of origine and geographical indication of olives and olive oils in Croatia
Europsko i svjetsko tržiÅ”te prehrambenih proizvoda zasiÄeno je novim proizvodima koji meÄusobno konkuriraju kakvoÄom i cijenom. NespecifiÄni proizvodi nisu u moguÄnosti nositi se s oÅ”trom konkurencijom sliÄnih proizvoda, a potroÅ”aÄi su Äesto nesigurni u kakvoÄu onoga Å”to kupuju. Zbog toga se javila potreba za zaÅ”titom proizvoda visoke kakvoÄe i specifiÄnih karakteristika. U tu svrhu EU je 1992. godine stvorila sustave: PDO (Protected Designation of Origin odnosno Oznaka izvornosti), PGI (Protected Geographical Indication odnosno Oznaka zemljopisnog podrijetla) i TSG (Traditional Speciality Guaranteed odnosno Oznaka ātradicionalni ugledā). Od 2005. godine proizvoÄaÄima u Hrvatskoj omoguÄena je ista zaÅ”tita za proizvode koje imaju i proizvoÄaÄi u zemljama EU, Äime se podiže razina konkurentnosti domaÄe proizvodnje i prepoznatljivost domaÄih proizvoda. Cilj ovog rada bio je pojasniti moguÄnosti zaÅ”tite maslinovog ulja i stolnih maslina, te iznoÅ”enjem praktiÄnih primjera dati doprinos u bržem integriranju Hrvatske u europsko i svjetsko tržiÅ”te proizvoda od maslina.European and world market of foodstuffs is glutted with new products competing by quality and price. Non specific products are not able to deal with a sharp competition among similar products, and consumers are often uncertain about the quality of purchased goods. Therefore the EU created in 1992 three types of food quality system: PDO (Protected Designation of Origin), PGI (Protected Geographical Indication) and TSG (Traditional Speciality Guaranteed). From 2005 Croatian producers have the same possibility of protecting their products as the EU producers, raising the competitiveness and identity of domestic production and products. The aim of the present paper was to clarify the possibilities for olive oil and table oil protection, as well as to give a contribution to faster integration of Croatia in to European and world olive products market by giving practical examples
Oil content in fruits of leading autochthonous olive varieties in Istria
Sadržaj ulja u plodu masline najvažniji je Äimbenik koji odreÄuje ekonomsku vrijednost pojedine sorte i jedan od kriterija za odreÄivanje stupnja zrelosti ploda, odnosno karakterizaciju sorte. OdreÄena je koliÄina ulja u plodu vodeÄih autohtonih sorti maslina u Istri, tijekom 2004. i 2005. godine, pomoÄu Soxtec aparata. Dobiveni podaci u zasebnim godinama upuÄuju na povezanost sadržaja ulja sa sortom, no njihova varijabilnost izmeÄu dvije godine za pojedinu sortu ukazuje na znaÄajan utjecaj vanjskih Äimbenika. Dobiveni rezultati variraju izmeÄu 21 i 48% ulja u odnosu na suhu tvar ploda, Å”to ukazuje na znaÄajan ekonomski potencijal ovih sorti.The oil content in an olive fruit is the most relevant factor determining the economic value of singular variety and one of the criteria for fruit maturity degree determination, and variety characterization as well. In this paper, the olive oil content in fruits of leading autochthonous olive varieties in Istria during crop seasons 2004 and 2005, using Soxtec apparatus, was determined. The results obtained reflect mostly the influence of the variety genetic potential on the oil content, when monitored in a single year, but its variation between the two years in a single variety shows the influence of external factors. The oil content on a dry weight basis in fruits of investigated varieties ranged from 21% to 48% which shows their high economic potential

Sterol, triterpen dialcohol and fatty acid profile of less- and well-known Istrian monovarietal olive oil
The aim of this study was to characterize monovarietal olive oils obtained from
two less known autochthonous cultivars (Bova and Buža puntoža) on the basis
of sterols, triterpene dialcohols and fatty acids profile for the first time, and three
monovarietal olive oils obtained from the most widespread autochthonous
cultivars (Buža, Istarska bjelica and Rosinjola) grown in Istria, Croatia.
Ī²-sitosterol, Ī-5-avenasterol and campesterol were the most abundant sterols in
all samples. Campesterol, Ī²-sitosterol and Ī-5-avenasterol most significantly
differentiated investigated oils. Bova oil had the highest amount of total sterols
(2964 Ā± 458 mg/kg). Istarska bjelica oil had a peculiar sterol composition with
exceptionally low Ī²-sitosterol (67%), high Ī-5-avenasterol (27%) and the
highest triterpene dialcohols percentages. Rosinjola and Istarska bjelica oils had
the highest monounsaturated fatty acids level, Buža oil had the highest
polyunsaturated fatty acids level, while Bova oil showed the highest level of
saturated fatty acids. Tested oils obtained from the most abundant cultivars
fulfilled all the demands of the current EU regulation required for virgin olive
oil regarding sterols, triterpene dialcohols and fatty acids, but Bova and Buža
puntoža oil slightly exceeded the upper limit for linolenic acid. Since cultivar is
the source of natural variation of sterols, triterpene dialcohols and fatty acids in
virgin olive oils, the knowledge about the content of these particular compounds
in different monovarietal oils from autochthonous cultivars is important to
determine possible disagreements with the demands of the current legislation
required for virgin olive oils, in order to anticipate possible false results
indicating adulteration

VALORISATION OF AUTOCHTHONOUS GRAPEVINE AND OLIVE VARIETIES IN ISTRIA
U sklopu veÄeg broja znanstvenih, tehnologijskih i VIP projekata odobrenih Institutu za poljoprivredu i turizam u PoreÄu provode se dugoroÄna istraživanja i aktivnosti usmjerene na oÄuvanje i valorizaciju autohtonih sorti vinove loze i maslina u lstri. To ukljuÄuje stvaranje baze podataka, terenski rad, morfoloÅ”ka mjerenja, laboratorijske, kemijske, sanitarne i genetiÄke analize te podizanje predmatiÄnih i matiÄnih nasada. Do sada je u istraživanje ukljuÄeno 16 sorata, odnosno 76 biotipa vinove loze i 64 stabla maslina. Posljednjih godina obavljen je veliki dio posla oko sakupljanja podataka, terenskog rada, obilježavanja, morfoloÅ”kih mjerenja i kemijskih analiza. Pojedine složenije laboratorijske analize su u tijeku , a pred nama su aktivnosti podizanja nasada klonskih kandidata autohtonih sorata vinove loze i maslina kao garancija trajnog oÄuvanja i moguÄnosti gospodarske valorizacije ovih sorti. NaglaÅ”avamo važnost ovih aktivnosti koje Äine osnovu dugoroÄnog razvoja vinogradarstva i maslinarstva u lstri.In the framework of several scientific, technological and VIP (Agricultural Research Council) projects in the Institute of Agriculture and Tourism a long term researches and activities aimed to preservation and valorisation of autochthonous grapevine and olive varieties in lstria are in course. This comprises a creation of database, fieldwork, morphologic measurements, chemical, sanitary and genetic laboratory analyses as well as promoter and mother plantings raising. Up today research considered 16 varieties, respectively 76 biotypes of grapevine and 64 olive trees. Last years was done a considerable job on data collection, fieldwork, labelling, morphological measurements and chemical analyses. Some complex laboratory analyses are in course and we are faced with pre-mother and mother plantation raising of clonal grapevine and olive candidates, as a guarantee for permanent preservation and possibility of economic valorisation for considered varieties. We point out the importance of these activities as a basis for long term viticulture and olive culture development in lstria

A Multidisciplinary Approach to the Characterisation of Autochthonous Istrian Olive (Olea europaea L.) Varieties
The Istrian region (Croatia) has a long olive growing and oil producing tradition as well as evident biological diversity in local olive (Olea europaea L.) germplasm. The olive oil is one of the most important typical food products in Istria. Considering the current tendency of consumers to select typical regional products, there is a need to define Istrian autochthonous olive varieties and to characterize the specificity of related oils. The aim of this study is to apply a multidisciplinary approach for that purpose. Morphological and molecular descriptions of four varieties (Buža, Buža puntoža, Istarska bjelica and Rosinjola) as well as the results of chemical analyses of their oils are reported. A total of 23 morphological traits, microsatellite profiles on 12 SSR loci, extractability index, olive oil minor compounds, colour and antioxidant activity have been determined and the results are reported in the following paper
