Quality of wholemeal wheat bread enriched with green coffee beans

Scientific studies have revealed that bioactive components of coffee play a preventive role against various degenerative diseases. Green coffee, in particular, is characterized by its unique composition and properties. The objective of this work was to investigate the influence of green coffee (Coffea arabica) beans (GCB) addition on the quality and antioxidant properties (AA) of the wholemeal bread. For bread preparation, flour form GCB, and wholemeal wheat flour, type 2000 were used. Wholemeal wheat flour was replaced with GCB flour at 1 to 5% levels. Loaf volume, texture, color and sensory properties of bread were determined. Furthermore, total phenolic content and antioxidant activity were evaluated. The results showed that bread supplementation with GCB had little influence on the bread volume. The highest volume of bread was obtained with 3 and 4% of GCB flour. The texture properties of bread crumb (hardness, elasticity, cohesiveness and chewiness) were slightly changed as a result of the GCB addition. The lightness of bread crumb decreased with the GCB addition (average from 46.3 to 42.6). Besides, the addition of GCB significantly enriched wheat bread with hydrophilic phenolic compounds. The phenolic compounds were highly bioaccessible in vitro. Moreover, the GCB addition enhanced antiradical activity of bread

Study on the physical and antioxidant properties of gluten-free bread with brown algae

The aim of the work was to determine the influence of brown algae on the physical, antioxidant, and sensorial properties when added directly into the gluten-free bread (GFB) recipe. Algae powder was added in the amounts of 2%, 4%, 6%, 8%, and 10% of the total flour content. Compared to the control bread, a larger volume was obtained using 4% of algae. With an increased content of brown algae, significant changes were noted in the color of the breadcrumb. Favorable changes in the texture were also observed. Brown algae addition significantly increased the antioxidant activity of GFB. Most importantly, antiradical compounds from the functional products were highly bioaccessible in vitro. The results confirm the possibility of the use of brown algae powder in the production of GFB. Because of the unpleasant taste on over-addition, the acceptable GFB can be obtained by adding 2% or 4% of the algae
