Neke su zemlje poku\u0161ale smanjiti \u0161tetne u\u010dinke topline u lancu branje-transport-skladi\u0161tenje preporu\u010duju\u0107i no\u0107no branje maslina. Tada je plod hladniji i mirisi i arome iz hladnijeg ploda bolje se \u010duvaju tokom hladne prerade (koja ne prelazi 27 stupnjeva Celziusa) te je ulje koje potom dobijemo aromati\u010dnije, ima bolje senzorne karakteristike. \u00a0Iako kao znanstvena preporuka no\u0107no branje zaslu\u017euje sve pohvale, u praksi se to pokazalo jako \u0161tetno za eko sustav. Naime, mediteranske zemlje koje su i najve\u0107i proizvo\u0111a\u010di maslinovog ulja \u0160panjolska, Portugal, Italija i Francuska nalaze se na ruti kojom se ptice selice u jesen sele na jug. Po no\u0107i one se odmaraju i spavaju u maslinicima. Na podru\u010djima gdje je uzgoj maslina potpuno automatiziran i berba se obavlja uz pomo\u0107 strojeva. Oni kao veliki usisava\u010di, ogromnom snagom usisavaju masline\u00a0sa stabla, a zajedno s njima i sve uspavane ptice koje se tu na\u0111u paralizirane bukom koje proizvode strojevi od kojih nisu u stanju pobje\u0107i.\u00a0 Procjene kazuju kako se samo u \u0161panjolskoj Andaluziji na taj na\u010din tijekom berbe maslina svake godine usmr\u0107ivalo 2,6 milijuna ptica, a u Portugalu 96.000 svake zime. U Francuskoj i Italiji nema statistike o pomoru ptica, ali i tamo bi se sasvim sigurno mrtve ptice mogle izbrojati u milijunima.\u00a0 Pro\u0161le je godine napokon takva no\u0107na berba zakonom zabranjena i u \u0160panjolskoj i u Portugalu, nakon \u0161to se do\u0161lo do brojke od stotinu usmr\u0107enih ptica po hektaru.<\/span><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Da je toplina kojom masline ulaze u preradu va\u017ean faktor\u00a0o kojem treba vodit ra\u010duna\u00a0dokazuju i najmodernije uljare koje danas da bi osigurale maksimalnu kvalitetu ulja, na ulazu u sam proces prerade imaju sustav kojim hlade masline.<\/span><\/span>
Po mi\u0161ljenju Sandija Chiavalona<\/a>\u00a0to je neophodno \u201ejer smo u zadnjih 10 godina primijetili da imamo plod koji ima previsoku temperaturu kada ulazi u preradu. Da bismo dobili vrhunsko ekstra djevi\u010dansko ulja, temperatura ploda u preradi mora biti 20 do 22 stupnja. Zato je dobro da se plod hladi jer u berbi plodovi dose\u017eu i 30 stupnjeva.\u201d Iako je to smjer koji \u0107e, nadamo se, slijedit i druge uljare danas jo\u0161 uvijek jako puno uljara na izlazu iz prerade ima previ\u0161e visoku temperatura ulja.\u00a0Po rije\u010dima Ante Duvnjaka<\/a>, vlastitim je mjerenjem u nekim uljarama nailazio i na temperature ulja na izlazu iz prerade od 50 stupnjeva celzijusa.<\/span><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Kontinuirano se  traga za novim mogu\u0107nostima smanjenja temperature plodova do po\u010detka prerade kako bi se u ulju sa\u010duvalo \u0161to vi\u0161e vrijednih nutrijenata, posebno fenola. Ono \u010dime maslinari i uljari mogu sami doprinijeti smanjenju temperature plodova je da ih pri berbi \u0161to manje o\u0161te\u0107uju i da ih do prerade skladi\u0161te u posude koje plodovima omogu\u0107avaju \u0161to bolje osloba\u0111anje to jest “isijavanje” topline iz njih u okru\u017eenje. Tradicionalno su na\u0161i stari ubrane masline dr\u017eali na hladnom, prostiru\u0107i ih po podu konobe, a ako su imali ve\u0107e posude, punili bi ih vodom ili morem i u njima dr\u017eali masline da im se ne \u201cupale\u201d. To \u201cupaljivanje\u201d koje upropa\u0161tava sve vrijednosti maslinovog ulja nastaje zbog grijanja unutra\u0161njosti plodova s dva izvora topline.
          \u25e6 Prvi izvor topline nastaje prirodnim biokemijskim procesom stvaranja ulja u plodu. Dok je plod na stablu, ta toplina odlazi u okolni zrak. U obranim plodovima, biokemijski procesi stvaranja ulja se nastavljaju, a masline uskladi\u0161tene gusto jedna do druge u posude, gajbe ili ko\u0161eve, griju jedna drugu.
         \u25e6 Drugi izvor topline nastaje u plodu zbog njegova o\u0161te\u0107enja, ulaskom larve maslinove mu\u0161ice, udarcem, nagnje\u010denjem, te gnjiljenjem. Stoga je izuzetno va\u017eno, osobito masline koje su ubrane pomo\u0107u tresa\u010da, dr\u017eati u \u0161to prozra\u010dnijim spremnicima jer od udarca \u0161tapa ili tresa\u010da, plod dobije ‘modricu’ i tada u njemu odmah zapo\u010dinje proces oksidacije. A \u0161to je toplina ve\u0107a i oksidacija je br\u017ea, te se plod vi\u0161e kvari.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Ako ne postoji dobro odvo\u0111enje ovih toplina sa uskladi\u0161tenih maslina\u00a0one se me\u0111usobno griju. Kako ne mo\u017eemo utjecati na prirodni izvor topline pri stvaranju ulja u plodu koji traje sve do prerade, i neke od drugih izvora topline kojim se plodovi me\u0111usobno griju, nastojimo da vrijeme skladi\u0161tenja bude \u0161to kra\u0107e i da je odvod topline sa uskladi\u0161tenih plodova \u0161to efikasniji.<\/span><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Kod transporta i skladi\u0161tenja maslina do prerade u uljari, izuzetno je va\u017eno da masline budu \u010duvane u prozra\u010dnim spremnicima koji dobro odvode toplinu. Za tu su svrhu maslinapravini inoks ko\u0161evi idealan izbor. Projektirani po znanstvenim preporukama, visine 15 cm, tako da u njima visina sloja maslina ne prelazi 12 cm, a ukupni im je kapacitet 7-8 kg. To je va\u017eno jer \u0161to je manji ukupni volumen maslina u spremniku, to se one bolje hlade.\u00a0 Kako se iz maslinapravinih ko\u0161ara na prirodni na\u010din odvodi toplina pogledajte u ovom videu.<\/span><\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Koliko je visoka temperatura kojoj su masline izlo\u017eene u spremniku, lako se provjeri i jednostavnim uranjenjem ruke. Optimalno je da ona bude \u0161to ni\u017ea kako ne bi do\u0161lo do gubitka u kvaliteti ulja. \u0160to je ve\u0107a temperatura u spremnicima i \u0161to vi\u0161e vremena masline provedu uskladi\u0161tene u spremnicima koji ne odvode dobro toplinu, to se dobije ni\u017ea kvaliteta ulja, a time je i uspjeh i prihod maslinara smanjen. \u00a0 <\/span><\/span><\/p>
