Celiac patients need to use gluten-free products to reduce gastrointestinal problems. Barley malt is effective properties of bakery products, but these additives cannot be used in gluten-free products. Also, in this study enzymatic sorghum malt in five levels (0, 1, 2, 3, 4 and 5%) was used as natural additives in gluten-free strudel. For this purpose, moisture, specific volume, porosity, firmness (1 and 72 hours after baking) and sensory properties were evaluated. Moisture was increased by increasing of malt in the formulation. The samples containing 1, 2 and 3% of malt (especially 3%) had the highest specific volume and porosity and the lowest firmness after 1 hours baking. All of samples were softer than blank (the sample without malt). Finally, the sample containing 3 % sorghum malt had the highest score of sensory properties.

The food researchers look to offer products with low- fat because of increasing awareness about health. In this project, low-fat composite (wheat-quinoa) cup cake was produced. Plantago major L. gum and water (1.5-7.5, 3-15, 4.5-22.5 and 6 -30%) was used as a fat replacer in levels of 0, 25, 50, 75 and 100 % in wheat-quinoa cake by completely randomized design. The samples containing 1.5 and 3 % gum had the lowest specific gravity and the highest porosity. Also, the highest consistency was indicated in the sample containing 3 % gum. On the other hand, the sample containing 3 % gum had the lowest firmness in 2 hours and 1 week after baking. This sample had the coherent micro structure. Finally, the samples containing 1.5 and 3 % gum had the best overall acceptability. Therefore, it can be said that the removal of 50% of oil in cake formulation was performed successfully.

In the present study the cow meat was replaced with camel meat (0, 25, 50, 75 and 100%) in burger formulation. Principal component analysis (PCA) was performed to understand quality variables differences and similarities of thirty-five sample burgers. Score plot, represents Principal component analysis of datasets derived from evaluated variables of thirty-five samples (samples contain of 0, 25, 50, 75 and 100% camel meat). Overall, six principal component was obtained which 65.8% of the total variance was concentrated into three first PCs. Cooked L*, cooked b* shrinkage, springiness, flavor, texture, juiciness, color and overall acceptability were the variables which separated by the first PC. The PC2 is characterized by the rest of instrumental texture parameters and the third by cooked a* and fat. The evaluation of score plot shows burgers contain higher amount of camel meat (50, 75 and 100%) had the higher moisture and fat content after cooking, higher scores in flavor, texture, juiciness and overall acceptability.

In this research, the effect of kombucha on physicochemical (pH, acidity, syneresis, viscosity, vitamin C and ethanol) and overall acceptability of yogurt samples were measured during 21 days of storage at 8ºC. Thus the amounts of 5, 10 and 15 %(V/V) of concentrate of kombucha layer grown up on black tea, with yoghurt starter, were inoculated to the milk containing 2.2 % fat. Meanwhile, the yogurt starter was applied for producing control sample. Fermentation in all samples was stopped when the pH reached 4.6. The results showed that during the storage, decrease of pH and increase of acidity were minor (p<0.01), and with raising the kombucha concentration, these changes were significantly less than control sample (p<0.01); syneresis in all samples (the same as control) increased while viscosity decreased (p<0.01) and increasing of kombucha concentration was caused increase of syneresis and decrease of viscosity (p<0.01); vitamin C decreased and ethanol increased very little (p<0.01) and as the kombucha concentration increased, the quantities of vitamin C and ethanol increased (p<0.01). Raising the kombucha concentration caused reduction of overall acceptability score in samples (p<0.01); and during storage, this score decreased (p<0.01) a little in comparison with that in control sample. After production and during storage, the best physicochemical and sensory properties was observed in sample containing yogurt starter and 5% kombucha concentrate.
