This research aimed to investigate effects of dough improvers (trehalose; TR, sucrose ester; SE and hydroxylpropylmethylcellulose; HPMC) on microstructural, textural, rheological and baking properties of frozen dough with virgin coconut oil using central composite design (CCD). Frozen dough containing dough improvers had higher values of all properties compared to frozen dough without dough imp...

Purpose: Vitamin D, a fat-soluble secosteroid, has a significant role in bone metabolism and helps calcium absorption in the body. Since vitamin D concentration is altered in fortified foods and dietary supplements, the actual amount of vitamin D may differ from the label value. Methods: In this study, the concentrations of vitamin D2 and D3 of fortified bread sample were analytically determine...

The consequences of addition of 1 % (w/w) glutenin of selected commercial wheat varieties, differing in their quantitative and qualitative gluten profile, to the base flour were investigated. The study was accomplished by employing an advanced 4 g bowl of MicrodoughLab (MDL). The elementary torque-time functions such as peak resistance,dough development time, dough stability, softening and ener...

Cereal Chem. 70(l):77-80 Soft white wheat flours from varied growing conditions were analyzed However, when the correction for protein content was not taken into for selected variables of gluten and components of flour lipid to identify account, total protein was shown to be negatively correlated with cookie those that are associated with baking quality as measured by cookie diameter. Among the...

Glycerol is the main compatible solute in yeast Saccharomyces cerevisiae. When faced with osmotic stress, for example during semi-solid state bread dough fermentation, yeast cells produce and accumulate glycerol in order to prevent dehydration by balancing the intracellular osmolarity with that of the environment. However, increased glycerol production also results in decreased CO2 production, ...

barbari is a traditional flat leavened iranian bread and one of the most popular breads consumed in iran and some other countries in the middle east. barbari stales very fast and its shelf life is very short. therefore, addition of bread improvers and anti-staling agents, such as hydrocolloids, is a suitable method for extending the shelf life of the bread. in the present study, the effect of v...

Cell-surface engineering (Ueda et al., 2000) has been applied to develop a novel technique to visualize yeast in bread dough. Enhanced green fluorescent protein (EGFP) was bonded to the surface of yeast cells, and 0.5% EGFP yeasts were mixed into the dough samples at four different mixing stages. The samples were placed on a cryostat at -30 degrees C and sliced at 10 microm. The sliced samples ...

The entire USDA-ARS maintained collection of 650 accessions of proso millet (Panicum miliaceum L.) was evaluated for the presence of accessions with waxy (amylose-free) endosperm starch. Six accessions, five of which derived from mainland China, were identified. Segregation ratios for waxy endosperm were evaluated in F2 and F3 populations derived from crosses between two waxy accessions, PI 436...
