Abstract
Zadatak ovog rada bio je ispitati utjecaj različitih udjela proteina sirutke na kvalitetu kruha bez glutena na bazi rižinog brašna i kukuruznog škroba. Protein sirutke dodavan je u tri različite koncentracije: 5 %, 10 % i 15 % u odnosu na ukupnu masu brašna i škroba. Probna pečenja su provedena u laboratorijskim uvjetima kao i ispitivanja kvalitativnih svojstava kruha bez glutena. Uzorcima kruha se odredio omjer visine i širine te specifični volumen. Uzorci su podvrgnuti analizi teksture (TPA), a za određivanje poroznosti koristila se metoda računalne analize slike. Provedena je i senzorska ocjena svojstava uzoraka kruha bez glutena. Rezultati istraživanja pokazuju da dodatak proteina sirutke ima pozitivan utjecaj na svojstva bezglutenskog kruha i to boljoj teksturi, senzorskoj prihvatljivosti i povećanju specifičnog volumena. Dodatak proteina sirutke doprinosi ukupnoj kvaliteti kruha bez glutena. Pozitivan utjecaj očituje se i u omjeru visine i širine, što može rezultirati mekanijim i kompaktnijom sredinom proizvoda. Okus i ukupna senzorska ocjena bezglutenskog kruha najbolje je ocijenjena za uzorke s dodatkom 5 % proteina sirutke.
Abstract (english)
The aim of this study was to investigate the influence of different proportions of whey protein on the quality of gluten-free bread based on rice flour and corn starch. Whey protein was added in three different concentrations: 5%, 10% and 15% in relation to the total mass of flour and starch. The baking tests were carried out under laboratory conditions, as were the tests on the qualitative properties of the gluten-free bread. Bread samples were used to determine the ratio of height to width and the specific volume. The samples were subjected to a texture analysis (TPA) and the porosity was determined using computer image analysis. Sensory evaluation of the properties of the gluten-free bread samples was also carried out. The research results show that the addition of whey protein has a positive effect on the properties of gluten-free bread, namely a better texture, sensory acceptability and an increase in specific volume. The addition of whey protein contributes to the overall quality of gluten-free bread. The positive influence also manifests itself in the height-to-width ratio, which can result in a softer and more compact the product. The taste and overall sensory evaluation of gluten-free bread was best in samples with 5% whey protein added.
