According to theresearchersfocused onthe roleof bread in thenational economyandtheuse ofnaturaladditivesto reducestalingrateand improvethe quantitative and qualitativeproperties ofstrategic products, So The aim of thisstudy was to investigatethe effect ofdifferent levels ofwatermelon(0, 1, 2, 4, 8 and 16%) on dough farinographypropertiesandmoisture content, specific volume, porosity andfirmness of semi volume Barbari bread. Inthis study, Image J software was used for porosity measurement. The resultsshowed thatwith the increasing ofwatermelonin the bread formulation, water absorption anddegree of softening increased butthe amount of dough stability decreased. While the mostdoughdevelopment timewas observedinsamples containing2% water melon. Also theresultsshowed thatthemelon water as a natural additive canincreases the amountof moisture content,porosity andspecific volumeanddecreased firmnessoftexture. So the highest moisture, specific volume andporosity were observed in ofthesamplescontainedrespectively16, 4and8% water melon. It should be notedthatsamples containing4% water melonhadthe lowestfirmness.

  Quality and shelf life of bread as a main diet has the great importance on health and the national economy. So the aim of this study was to investigate the effect of water, melon water, oil, cow milk and soy milk as a glazing component of baguettes on the moisture content, specific volume, texture, crust color and overall acceptance of final product. In this study, Image J software was used for crust color measurement. Based on results, the samples have melon water, cow's milk and soy milk glaze had the highest moisture content. However, the samples containing water and water melon glaze had the highest specific volume. The results clearly showed that the samples were coating by water and melon water had the lowest firmness respectively in 2 and 72hr after baking. This indicates that melon water as a coating agent is better for preserving moisture and to retard the staling. In addition the highest amount of L* value and a* value and overall acceptance score in organoleptic evaluation were observed in the two samples coating by melon water and cow's milk. In general we can say that glazing is one of the techniques that are simple, low-cost addition to being a great role in maintaining and even improving the quantity and quality of bread. Also according to the results of this study, melon water, with its unique function as a new glaze in bakery industry is introduced.
