The aim of the present study was to evaluate Raman spectroscopy in determining changes that occur structure gluten proteins induced during bread dough mixing. spectra were measured directly within dough. Three particular phases mixing studied: under-mixing, optimum and over-mixing. A thiol blocking reagent, Tris(2-carboxyethyl)phosphine (TCEP) then used reduce disulphide bonds confirm important...

Rheology of the solid and melted cheese depends upon their functional properties. Farinograph is used for quality determination of wheat flour dough. Determination of the rheological properties of dough and dough like food materials from Farinograph is easy while study of cheese characteristics is very difficult and complicated. The present study is therefore designed for the possibility of qua...

Hybridization study of two Saccharomyces cerevisiae baker’s yeast strains isolated in Thailand, IFRPD 6080 and IFRPD 6081, was carried out. Rare-mating technique has been employed with haploid and diploid mating strains of Japanese baker’s yeast. Polyploid (triploid and tetraploid) hybrids produced from rare-mating were selected and induced for sporulation. Screening of segregants obtained from...

A three-dimensional (3-D) bio-imaging technique was developed for visualizing and quantifying the 3-D distribution of yeast in frozen bread dough samples in accordance with the progress of the mixing process of the samples, applying cell-surface engineering to the surfaces of the yeast cells. The fluorescent yeast was recognized as bright spots at the wavelength of 520 nm. Frozen dough samples ...

Whole-grain bakery products and cereals are valuable sources of dietary fiber, vitamins, and trace elements. However, the presence of phytate, could decreases mineral bioavailability due to its chelating properties. In this study, the effect of fermentation and baking on the phytate content of different bakery products was measured by HPLC; the mineral availability in bakery products during pro...

Investigations were conducted on the level of the overall proteolytic activity in flour fractions as well as fine and bruise bran, obtained from four varieties of wheat (‘Zyta’, ‘Pegassus’, ‘Sukces’, ‘Tonacja’), subjected to pre-harvest sprouting. Moreover, an analysis was conducted on the effect of pre-harvest sprouting on the functional properties of flour, determining the physical properties...

With the aim of improving nutritional profile and antioxidant capacity of gluten-free cookies, blueberry pomace, byproduct of juice production, was processed into a new food ingredient by drying and grinding and used for a gluten-free cookie formulation. Since the quality of a baked product is highly influenced by the baking conditions, the objective of this work was to optimize the baking time...

The aim of this research was to study the effect of fortified pan bread with Lupine flour (5, 10 and 15 %) on the chemical, rheological and nutritional properties. Lupine flour showed higher levels of crude protein, ash, crude fat and fiber than the wheat flour. Conversely, wheat flour showed higher contents in carbohydrates. Rheological studies of dough showed clear differences between wheat f...

High-molecular-weight glutenin subunits (HMW-GS) composition was analyzed by sodium-dodecyl-sulfatpolyacrilamid-gel electrophoresis (SDS-PAGE), while the quantitative determination of total HMW-GS was obtained by reversed phasehigh performance liquid chromatography (RP-HPLC). Considering HMW-GS composition, the most frequent subunits at Glu-A1 locus were N, at Glu-B1 locus 7+9 and at Glu-D1 loc...

A 20-year-old woman developed anaphylaxis after eating pizza on 4 different occasions in 2 restaurants. Both restaurants made their pizza dough with a mixture of wheat and buckwheat flours. A prick-to-prick test with buckwheat flour was positive. Skin prick tests and specific immunoglobulin E responses to soybean and peanut were weakly positive while the response to buckwheat was negative. We r...
