A laboratory scale no-time frozen dough procedure that approximates Romanian commercial practice has beendeveloped and used to study the effects of ingredients and processing conditions on the bread quality of a straightgrade wheat flour during prolonged storage (2 days to 26 weeks). All treatments (baking absorption level, mixingenergy input, mixer type, fermentation and intermediate proof times, removal of oxidant and/or doughstrengthening conditioners and partial freeze-thaw cycles) had significant effects (P<0.05) upon bread quality (loafvolume and/or bread score). In general, these effects were more pronounced with extended frozen storage time.High baking absorption, undermixing, bulk fermentation (> 1 h) and removal of oxidant and/or surfactants hadthe most dramatic effects. Addition of a very strong flour at 30% to strengthen the wheat flour had no significanteffect (P>0.05) upon bread quality under optimum conditions.

The effects of the addition of 0–3.0 wt% α-cyclodextrin (α-CD) and γ-cyclodextrin (γ-CD) on the quality of wheat flour as well as the texture and the aging of prebaked bread were evaluated. The addition of α-CD and γ-CD increased the ability of wheat flour to absorb water and shortened the times of dough formation and stabilization. Amylase activity slightly increased after using 2.0 and 3.0 wt% of α-CD and γ-CD, respectively. Moreover, the addition of α-CD and γ-CD increased the fermentation height and gas retention ability of dough. Dough samples containing 2.0 wt% α-CD and 3.0 wt% γ-CD showed the highest fermentation heights and gas retention volumes, respectively. Dough gas production increased with the addition of γ-CD. Gas production by dough samples containing more than 2.0 wt% α-CD exceeded that by samples in the control group. The results of the texture crumb of bread and specific volume tests revealed that the addition of 2.0 wt% α-CD and 3.0 wt% γ-CD reduced bread hardness and increased bread elasticity, resilience, and specific volume. The optimal α-CD and γ-CD contents were identified as 2.0 wt% and 3.0 wt%, respectively. The addition of 2.0 wt% α-CD and 3.0 wt% γ-CD delayed the aging of prebaked bread and reduced the hardness of prebaked bread during different weeks of storage, which may be due to decreasing the melting enthalpy of starch crystals. This work elucidated the mechanisms underlying the effects of CD addition on prebaked bread quality.

Fermentation Parameters

Amaranth flour from germinated (GA) and non-germinated (A) seeds (0%-C, 5%, 15%, 25%) were mixed with wheat flour for breadmaking. Fermentation parameters of dough (time-tf, maximum volume-Vmax) were obtained. Specific volume (Vsp) of breads, crust color, texture and relaxation of crumb were analyzed. A high amount of germinated amaranth flour decreased Vmax and increased tf, obtaining breads with low Vsp and darkness crust. A firmed and chewy crumb, although with a more aerated structure (high area occupied by alveoli) was obtained. The GA25 bread presented the softer crumb. The elastic modulus-E1 of crumb increased and the relaxation time-T1 decreased with higher amounts of amaranth flour, suggesting the formation of a more structured crumb; mainly in the case of non-germinated amaranth flour. Wheat flour resisted the inclusion of 25% of germinated amaranth seeds (GA25) without substantial changes in bread quality.

The study of the effect of the modified atmosphere packaging on quality of the bread was done after replacing wheat flour with amaranth flour in replacement of wheat flour for 0, 5, 10 and 15% by weight. The bread was stored for one, three and seven days in the ATM, 100% N2 and 30% CO2. The study proved the 30% CO2 modified atmosphere to be the optimal storage condition. It allowed to preserve volume, water content and contributed at least to increase in hardness of bread, which with the addition of amaranth flour decreased. The colour of bread during storage was characterised by the increase in L* parameter and decrease in a* and b*. For the decreased storage time, the effect was opposite. The replacement by 5% of amaranth flour increased the polyphenol content and did not affect bread quality.

Vital Wheat Gluten

Purpose The purpose of this paper is to evaluate the viscoelastic quality of commercial vital wheat glutens from different origins (A and B) through simple tests, and correlate these results with dough rheological parameters measured using more complex equipment (farinograph and extensograph) and with bread quality characteristics (specific volume and crumb firmness) obtained from wheat flour fortified with 7 g/100 g of vital gluten. Design/methodology/approach For the evaluation of vital gluten quality, two commercial vital wheat gluten named A and B were used. The simple tests performed with these samples were wet and dry gluten contents and index gluten, extensbility test and expansion test. The Pearson correlation was performed among data from dough rheological tests (farinograph and extensograph) and bread quality parameters (specific volume (SV) and crumb firmness) obtained from the fortification of wheat flour with 7 g/100 g of VGA or VGB (previous work, data not shown). Findings The simple tests showed differences in the viscoelastic properties of vital gluten A and B; vital gluten A presented higher elasticity and lower extensibility than vital gluten B, and the gluten ball of sample A presented higher SV. By correlation analysis, it was verified that the simple tests studied may be useful to assess the baking performance of commercial vital gluten when this product is added to wheat flour for its fortification. Furthermore, the results indicate the need for more information on vital wheat gluten proteins for its commercialisation and use. Originality/value This work is very important, not just for the scientific community, but also for the bakery industry, that requires more information about vital wheat gluten before its use in bread making. As there are great differences in the protein quality of commercial vital wheat glutens and their functionality, the study was developed to solve this problem.
