Abstract

Proso i rogač su prirodne sirovine koje mogu poboljšati nutritivnu vrijednost te tehnološka svojstava bezglutenskog kruha. Kisela frementacija smjese brašna rogača, prosa i posija prosa prije dodatka u zamjes za pripremu bezglutenskog kruha dodatno može unaprijediti trajnost bezglutenskog kruha. Cilj ovog rada bio je ispitati utjecaj dodatka smjese brašna rogača, prosa i prosenih posija te utjecaj kisele fermentacije iste smjese na kvalitetu bezglutenskog tankog kruha. Kvaliteta kruha određena je mjerenjem fizikalnih svojstava kruha s naglaskom na teksturu kruha tijekom 72 sata. Kruh obogaćen rogačem i prosom te kruh s dodatkom kiselog tijesta pokazali su manju tvrdoću i žvakljivost sredine kruha u odnosu na kontrolni kruh. Kohezivnost i elastičnost sredine kruha smanjile su se kroz vrijeme za sve uzorke. Dodatak kiselog tijesta u bezglutenski kruh uzrokuje manje izražene promjene parametara teksture kroz vrijeme u usporedbi s ostalim uzorcima.

Abstract (english)

Millet and carob are natural raw materials that can improve the nutritional value and technological properties of gluten-free bread. Acidic fermentation of the mixture of carob flour, millet flour and millet bran can additionally improve the shelf life of gluten-free bread. The aim of this thesis was to examine the influence of the addition of a mixture of carob and millet and the effect of acid fermentation of the same mixture on the quality of gluten-free flat bread. Quality was determined by measuring the physical properties of bread with an emphasis on the texture of the bread during 72 hours. Bread enriched with carob and millet and sourdough bread showed a decrease of bread crumb hardness and chewiness in comparison to the control bread. Cohesiveness and elasticity of the bread crumb decreased over time for all samples. The addition of sourdough to gluten-free bread causes less pronounced changes in texture parameters over time compared to other samples.
