Abstract
Cilj ovog diplomskog rada je bio ispitati utjecaj dodatka različitih emulgatora na svojstva krem-proizvoda bez šećera s dodatkom kakaove ljuske i zaslađivača. Krem-proizvod je proizveden u kugličnom mlinu pri temperaturi od 50 °C s 3 kg kuglica te 60 okretaja po minuti. Krem-proizvodi su imali različite omjere kakaove ljuske i ksilitola (~50:50, ~40:60, ~30:70, ~20:80, ~10:90, 0:100) i stevije kao zamjenu za šećer. Nakon proizvodnje krem-proizvoda ispitivala su se sljedeća svojstva: boja, koloidna stabilnost, tekstura, aktivitet vode, specifični volumen i prividna gustoća. Dodatkom kakaove ljuske je došlo do znatne promjene boje, no kako se smanjivao udio kakaove ljuske, a povećavao udio ksilitola uzorci su bili sve svjetliji. Koloidna stabilnost se povećavala kod uzoraka koji su sadržavali PGPR i citrem. Aktivitet vode se povećavao dodatkom PGPR-a i citrema i smanjenjem udjela kakaove ljuske. Dodatkom kakaove ljuske se povećavala čvrstoća i otpor smicanju, ali dodatkom PGPR ili citrema mazivost je bila poboljšana.
Abstract (english)
The aim of this thesis was to examine the effect of the addition of various emulsifiers on the properties of sweet spreads with added cocoa shell and sweeteners. Sweet spreads were produced in a ball mill at a temperature of 50 °C with 3 kg of ball and with 60 revolutions per minute. Sweet spreads had different ratios of cocoa shell and xylitol (~50:50, ~40:60, ~30:70, ~20:80, ~10:90, 0:100) and stevia as a substitute for sugar. After the production of the sweet spreads, the following properties were examined: color, colloidal stability, texture, water activity, specific volumes and apparent density. Addition of cocoa shells caused significant color changes, but as the cocoa shell content decreased and the xylitol content increased the samples were lighter. Colloidal stability was increased in samples containing PGPR and citrem. Water activity was increased by addition of PGPR and citrem and by a decrease in cocoa shell content. Addition of cocoa shell increased firmness and shear strength, but addition of PGPR or citrem improved spreadability.
