Flour mixture of rice flour, corn and cassava starch in the production of gluten-free white bread

The aim of this work was to determine the quality characteristics (physical and chemical), total phenols (TPC), and antioxidant activity (DPPH Radical Scavenging method) of pomegranate whole fruit bagasse (PWB) incorporated bread. The pomegranate whole fruit bagasse powders were incorporated into yeast leavened bread at 5 g and 15 g levels (flour basis). The results showed that the mineral content varied and the antioxidant potential of breads was significantly improved. The highest increase in antioxidant potential was measured in the breads made with 15 g w/w PWB.

The growth of lactic acid bacteria during liquid-state fermentation of buckwheat fl our and changes in pH during the process were analyzed. Eight strains of Lactobacillus were selected as the most active strains used to obtain new fermented fl ours. Physical properties of buckwheat water biscuits formulated from these fermented fl ours were studied.The hardness of freshly prepared biscuits was affected by the lactic acid bacteria applied, with its highest value noted for the water biscuits made of buckwheat fl our fermented by L. plantarum IB. Signifi cantly greater differences in hardness values of water biscuits were noted after 24 h storage. Moreover, water biscuits made of the fermented fl ours were lighter and had a higher browning index as compared to the control biscuits prepared from unfermented buckwheat fl our. The obtained results demonstrate the feasibility of selecting lactic acid bacteria for the fermentation of buckwheat fl our focusing on some physical properties of the water biscuits.

In this study, the effects of 18 different additive formulas constituted with xanthan and hydroxypropylmethylcellulose (HPMC) gums (hydrocolloids) were examined in the manufacture of corn starch based gluten-free bread. The additives used as alone or in combinations in the bread manufacture. It was also added with mono-and diglyceride based gel preparations and diacetyl tartaric acid esters of mono-and diglycerides for improving glutenfree bread characteristics. The volumes and softness of the breads have been measured as maximum when HPMC was used alone in increasing order from 1 to 2%. While HPMC gum improved the volume and softness of bread more than Xanthan gum, Xanthan gum improved the grain structure of crumb more than HPMC. In general, these hydrocolloids gave a good quality of bread in terms of moisture content, grain structure and Neumann baking coefficient values, when they were used with combinations rather than being used individually. Addition of surfactant to all combinations always enhanced the grain structure of bread. In contrast, it either worsened or did not change the volume and softness of the bread.
