Abstract
U ovom diplomskom radu analiziran je utjecaj različitih udjela proteina bjelanjka jajeta na svojstva bezglutenskog kruha od rižinog brašna i kukuruznog škroba. Ispitivane su tri koncentracije bjelanjka jajeta (5 %, 10 % i 15 %) u odnosu na ukupnu masu brašna i škroba. Za potrebe istraživanja, provedena su probna pečenja u laboratorijskim uvjetima, a kvalitativna svojstva kruha bez glutena ispitana su kroz analizu omjera visine i širine, specifičnog volumena, teksturalnog profila, i poroznosti uzoraka analizirane računalnom analizom slike. Rezultati istraživanja ukazuju na pozitivan utjecaj dodatka bjelanjka jajeta na svojstva bezglutenskog kruha, uključujući povećanje specifičnog volumena, promjene u omjeru visine i širine, promjene u boji, teksturi i senzorskoj prihvatljivosti. Zbog činjenice da su u uzorcima kruha bez glutena s 15% bjelanjka jajeta senzorski ocjenjivači primijetili preintezivan miris i okus koji podsjeća na jaja, najbolje ocjene dobili su uzorci s dodatkom 10 % bjelanjka jajeta. Može se zaključiti da dodatak bjelanjka jajeta poboljšava kvalitetu kruha bez glutena te doprinosi njegovoj senzorskoj prihvatljivosti. Ovi rezultati imaju potencijalnu primjenu u razvoju bezglutenskih proizvoda visoke kvalitete s poboljšanim nutritivnim svojstvima.
Abstract (english)
This master's research examined the influence of different proportions of egg albumin on the properties of gluten-free bread made from rice flour and cornstarch. Three concentrations of egg albumin (5%, 10%, and 15%) were investigated relative to the total mass of flour and starch. For the purposes of the study, test baking was conducted under laboratory conditions, and the qualitative characteristics of gluten-free bread were assessed through the analysis of height-to-width ratio, specific volume, textural profile, and porosity using computer image analysis. The research results indicate a positive impact of egg albumen protein addition on the properties of gluten-free bread, including increased specific volume, changes in height-to-width ratio, alterations in colour, texture, and sensory acceptability. As the sensory testers found too intense odour and taste reminiscent of eggs in the samples of gluten-free bread with 15% albumin, the samples with the addition of 10% albumin received the highest scores. It can be concluded that the addition of egg white improves the quality of gluten-free bread and contributes to its sensory acceptance. These findings have potential applications in the development of high-quality gluten-free products with improved nutritional properties.
