| الوصف: | U radu je ispitana proizvodnja tekućih koncentrata proteina sirutke pomoću ultrafiltracije, toplinske denaturacije i homogenizacije, te ultrafiltriranog permeata, koncentriranog reverznom osmozom. Proizvedeni su fermentirani napici inokulacijom kefirnih zrnaca (svježih i odmrznutih) i/ili komercijalnih probiotičkih kultura u tekuće koncentrate proteina sirutke i u koncentrirane ultrafiltrirane permeate, te uzgojem na 25 °C tijekom 24 sata. Ocjenjena su i uspoređena fizikalno-kemijska svojstva dobivenih napitaka, i to: pH-vrijednost, titracijska kiselost i viskoznost, te udjeli čvrste tvari, pepela, masnoća i proteina. Broj živih stanica mikroorganizama određen je neposredno nakon inokulacije (0 h), tijekom fermentacije (nakon 12 i 24 h) i tijekom skladištenja u hladnjaku (nakon 48, 168 i 336 h). Fermentirani su napici imali zadovoljavajuća fizikalno-kemijska i senzorska svojstva, a sadržavali su više od 7 log CFU/mL laktokoka i laktobacila, te 6 log CFU/mL kvasaca nakon 14 dana skladištenja, što je u skladu sa standardima međunarodnih organizacija, kao što su Europska agencija za sigurnost hrane (engl. European Food Safety Authority, EFSA) i američka Agencija za hranu i lijekove (engl. Food and Drug Administration, FDA). Zaključeno je da se frakcioniranjem sirutke i postupcima razvijenim u ovom radu mogu proizvesti novi funkcionalni napici. ; This work focuses on the production of liquid whey protein concentrates by ultrafiltration followed by thermal denaturation and homogenization of the ultrafiltrated concentrate, as well as on the production of ultrafiltrated permeates concentrated by reverse osmosis. Kefir grains (fresh and thawed) and/or commercial probiotic bacteria were inoculated in both liquid whey protein concentrates and concentrated ultrafiltrated permeates and grown at 25 °C for 24 h for the manufacture of fermented drinks. The physicochemical characterization (pH, titratable acidity, viscosity, and content of total solids, ash, fat and proteins) of the obtained drinks was then assessed and ... |
