Physicochemical And Functional Properties

The consumer demand is increasing for composite flour based bakery products like biscuits. The incorporation of brown rice flour can be justified in composite flour based biscuits as it has beneficial nutraceutical properties and its gluten-free nature can play important role in preventing celiac problem. The physicochemical and functional properties of brown rice and wheat flour were studied and biscuits were prepared with the incorporation of brown rice flour in 0, 5, 10, 15 and 20 % with the wheat flour to assess the quality and acceptability of the biscuits. The water absorption capacity of brown rice flour was lower than that of wheat flour (p?0.05), whereas oil absorption and foaming capacity of brown rice flour were significantly higher than that of wheat flour (p ?0.05). The brown rice flour had higher least gelation concentration (30.66%) as compared with wheat flour (20.33%). As the concentration of brown rice flour was increased, spread ratio of biscuits decreased. The biscuits containing 5, 10 and 15% brown rice flour indicated that addition of increasing level of brown rice flour had higher ash, fat, moisture and crude fiber contents, while protein and total carbohydrate contents found lower in the biscuits. Statistical analysis of biscuits containing various amount of brown rice flour (0, 5, 10, 15 and 20% brown rice flour) showed that control biscuits (0% brown rice flour) secured the highest score for color, flavor, texture and overall acceptability, which is followed by biscuits containing 10, 5,15 and 20% brown rice flour.

Aims: The aim of the study was to evaluate the physicochemical, sensory and functional properties of coconut flour (CF), coconut wheat composite flour (CWCF) and Cake produced from CF and CWCF. Methodology: Flour was prepared from matured ripe coconut fruit (CF). It was then blend with wheat flour (WF) into coconut wheat composite flour (CWCF) to produce cake. The CF and CWCF were subjected to proximate composition and functional properties analyses. Also, the physical properties, proximate composition and the sensory attributes of the cakes produced from CF and CWCF were determined. Results: The moisture content of CF and CWCF ranged from 4.5 to 9.04 g/100 g, the ash content of CF and CWCF ranged from 4.10 to 6.41 g/100 g and the dietary fiber content of CF was 11.16 g/100 g. CWCF exhibited a higher (87.1± 0.6) water absorption capacity and packed bulk density (0.79 ± 0.3 g/ mL). In this study, the cake volumes increased significantly (P < 0.05) in wheat flour (WF) as compared to CWCF and CF. The specific cake volume observed ranged from 1.48 to 2.01 mL/g. The blend of 50% coconut and 50% wheat flour increased significantly (P < 0.05) the moisture content of the CWCF cakes. The total carbohydrate content of the cakes varied from 20.40 ± 0.02 g/ 100 g to 63.05±0.14 g/ 100 g. Fat, ash and crude fiber and minerals (Ca, K, P Zn, Mg and Fe) increased in CWCF cakes. The sensory analysis conducted showed that there was a significant difference (P < 0.05) between CF cakes, WF cakes and CWCF cakes in the sensory qualities of appearance, texture, flavour and overall acceptability. In terms of appearance, the panelists scored coconut cake highest, but was significantly different (P < 0.05) from coconut wheat cake and wheat one. The least liked sample in terms of texture was wheat one. Conclusion: The present study underscored the potential application of coconut flour in the production of cake and possibly other bakery products.

Activation Conditions

Grain activation is a natural processing technique that can be used to produce modified flours without chemical modification. Functional characteristics of brown rice flour as influenced by grain activation time and temperatures were investigated. Germination temperatures at 25 ℃, 30 ℃ and 35 ℃ and time for 12, 24, 36 and 48 h significantly influenced the functional properties of flour with modification of starch, protein and high enzymatic activity. Significant decrease in the bulk density, water absorption and swelling power of brown rice flour was observed in comparison to non-germinated flour. Gel consistency and oil absorption capacity of brown rice flour increased as the grain activation time and temperature were increased. Native flour had lowest emulsion and foaming properties, while increase in grain activation time and temperature enhanced the emulsifying and foaming properties of flour. Paste clarity of native flour was 54% which was reduced to 25.17%; however, increase in germination time and temperature increased the % synersis values of germinated flour. Native flour had least gelation concentration of 12% which increased to 25% after 48 h of germination at 35 ℃. Overall, germination can be used as a natural way to modify the functional properties of brown rice flours for their utilization in variety food products.

The paper considers how gluten-free flours, in particular, those made from coconuts and brown rice, can be used in  the  technology of gluten-free chocolate muffins in order to expand the  range of special purpose products. Studies by domestic and foreign authors dedicated to using different flour types in today’s gluten-free technologies have been analysed. It has been proved that wheat  flour  can be fully replaced with gluten-free flour mixtures in the recipe of chocolate muffins. Analysis of the chemical composition of  coconut flour has shown its higher fat content, compared with wheat flour, and twice as much protein and dietary fibre (18%). Coconut flour exceeds wheat flour not only in the main macronutrients, but also in the content of the main minerals. Brown rice flour, too, contains more fats and vitamins of the B-group than wheat flour does, and is a source of sodium, magnesium, phosphorus, silicon, and sulphur. It contains up to 80% of starch and, like coconut flour, is gluten-free. Replacing wheat flour in the classical muffin recipe with mixtures of coconut and brown rice flours in the ratios 30:70, 40:60, and 50:50 reduces the moisture content and density of the dough. The moisture content in the finished muffins, too, is lower by 0.7, 1.2, and 1.5% respectively. It has been confirmed that if the gluten-free flour mixture contains over 50% of coconut flour, it reduces the specific volume of resulting muffins and worsens their quality parameters. The Harrington method was used to estimate the comprehensive quality index of the chocolate muffins. This has shown that full substitution of wheat flour for a mixture of gluten- free flours in the ratio 40:60 (coconut flour:brown rice flour) allows achieving the best-balanced sensory characteristics. Gluten-free muffins have a pleasant brown colour of the crust, their crumb is quite soft, homogeneous, and porous, with a balanced taste and an aroma of cocoa combined with light coconut notes.

This study evaluated some quality attributes of pancakes from peeled and unpeeled sweetpotato flours and cassava starch. Cassava starch was substituted up to 30% of the total composite flour. The proximate composition, colour, carotenoid and functional properties of the different flour blends were determined. The flour blends were processed into pancakes and the proximate composition and sensory acceptability of the pancakes were determined. Data obtained were subjected to analysis of variance. The result showed that they were significant differences (p<0.05) in the functional properties of the flour blends. Bulk density, Water absorption capacity, Oil absorption capacity, swelling capacity ranged from 0.70 to 0.78 g/ml, 1.87 to 2.30 g/ml, 1.02 to 1.40 g/ml and 5.18% to 6.66%  respectively. There were significant differences (p<0.05) in the proximate composition of the pancake samples. The values ranged from 42.76 to 45.53%, 2.13 to 3.98%, 9.06 to 10.34%, 5.01 to 7.18%, 3.75 to 6.01% and 29.19 to 35.33% for moisture, ash, fat, protein, crude fibre and carbohydrate contents, respectively. Pancake produced from 100:0 peeled and unpeeled sweetpotato flour had the highest score for overall acceptability which can compare favorably, with pancakes from wheat flour which is the control sample. In conclusion, sweetpotato flour blended with cassava starch at different ratio gave good proximate and functional properties which resulted in pancakes of good quality attributes.

Roasting temperature and time are important parameters in the process of roasted germinated brown rice flour (RGBRF), which cause the loss of bioactive ingredients and sensory value of the product. During roasting and storage, fat oxidation is also one of the problems that reduce the quality of RGBRF. In order to complete the RGBRF process, experiments using different temperature and time as 160oC, 200oC, 240oC for 10 to 30 mins were done to find the best roasting conditions. To limit the oxidation of fat during the processing and preserving RGBRF, ergothioneine (ERG) extract from enoki mushroom were supplemented at 3%, 5%, 7% and 10% (w/w) before roasted, the product was then ground and put into two types of packaging (PA and aluminum), vacuum seamed and stored at room temperature for 8 weeks were carried out. The results showed that germinated brown rice (GBR) which supplemented 3% of the extract before roasted at 200oC for 30 mins showed the best quality in term of sensory value, γ-aminobutyric acid (GABA) content and helped to limit fat oxidation as well as maintained stable quality after 8 weeks of storage in PA and aluminum packaging. In addition, the results from in vitro of starch resistance and in vivo of sugar absorption capacity in rats showed that RGBRF did not significantly change the GI index as well as the ability to absorb sugar compared to unroasted product. The results indicated that RGBRF should be used as a nutritious food with the ability to supplement bioactive compounds to the people at risk of lifestyle diseases.

In order to produce dough with a lower gluten content, more enriched with the rice components and satisfactory rheological properties, the rheological properties, energetic value and cake baking properties of wheat and white or brown rice flour in shares from 3 to 30% (w/w) were investigated in this paper. The water absorption in wheat-rice flour mixtures was less and decreased to 53.5 % and 54.0 % along with the increase of the white and the brown rice flour share, respectively, than in wheat flour, where it was 58.8%, In the dough made from rice flour a gluten network had thinner filaments, about 2 and 1 ?m in width for white and brown rice flour, respectively, compared to those in the dough from wheat flour only, where it was about 7 ?m. The dough from rice flour had almost twice as higher gelatinization maximum as the gelatinization maximum of the wheat flour only. The energetic values of the dough from rice flour were smaller than the energetic value of the wheat flour, for only 1.32%. Based on Cluster analysis, the white or brown rice flour share of 20% was pointed out.
