Physicochemical properties of fermented and non-fermented rice bran flour and its utilization in bread making

Rice bran was subjected to natural fermentation for 4 days and investigated for its physicochemical, antioxidant, phytochemical, functional properties and mineral content. In addition, the fermented and non-fermented rice bran flours were supplemented with wheat flour in several ratios for baking bread. The proximate composition results obtained showed that fermented rice bran flour possessed protein content of 5.68%, fibre (37.8%), fat (2.97%) and carbohydrate (31.06). It was observed that the total phenol content for non-fermented rice bran flour (362.69 GAE µg/ml) was higher than fermented bran flour (359.15 GAE µg/ml). However, the ability of the samples to scavenge 1,1-di phenyl-2-picrylhydrazyl (DPPH) radical was higher in fermented flour (57.0mg/ml) than in non-fermented sample (55.0 mg/ml). The result of the qualitative analysis of the phytochemical screening revealed that only saponin was present in the rice bran flours. The mineral composition of the non-fermented and fermented rice bran flours revealed that the flours possessed magnesium (0.19%-0.18%), sodium (0.06%-0.17%), calcium (0.08%-0.13%) and potassium (0.03%-0.02%). The physical properties of bread sample at 20% rice bran flour supplementation showed that there was no significant difference between loaf volume of the wheat flour bread and non-fermented rice bran bread (360cm3) while there was significant difference in the loaf volume of fermented rice bran bread (281cm3). It was observed that the fermented rice bran bread had the highest fibre content (1.83%), followed by non-fermented rice bran bread (1.37%) and wheat flour bread (0.95%). The sensory analysis revealed that both the fermented and non-fermented rice bran breadswere scored above average in all sensory parameters although wheat flour bread was preferred.Â

Objects were observed in this study was to determine the final result of the manufacture of bread to test the texture, color, flavor, and aroma with a mixture of flour bran, the method of making the same, cooking equipment are the same, long fermentation time the same, the temperature of the oven the same and roasting the same time.

Synergistic effect of different dietary fibres in pasta on in vitro starch digestion?

Pasta is traditionally manufactured using only durum wheat semolina, but it is possible to incorporate other flours or ingredients into pasta in order to increase its nutritional value to the consumer, compared to conventional pasta. For this reason, pasta was prepared substituting durum wheat semolina with 15% of enriched dietary fibre flours (Glucagel, inulin Raftiline® HPX, inulin Raftiline® GR, psyllium and oat). Moreover, all dietary fibres (excluded Glucagel) were added in combination in order to evaluate their possible antagonistic or synergic effect on predicted glycaemic response. In general, all enriched dietary fibre pasta sample showed a significant decrease (except for pasta containing a combination of 7.5% inulin Raftiline® GR and 7.5% oat bran flour) in reducing sugars released and standardised AUC values compared to control pasta. However, this study showed that the combination of dietary fibres in pasta formulation led to an antagonistic effect on the predicted glycaemic response.

Improvement of fatty acid profile and studio of rheological and technological characteristics in breads supplemented with flaxseed, soybean, and wheat bran flours.

Functional breads constitute an interesting alternative as vehicle of new essential fatty acids sources. The aim of this study was to improve the fatty acids (FA) profile of bakery products, producing breads with low saturated fatty acid (SFA) content and with high polyunsaturated fatty acid (PUFA) content, through partial substitution of wheat flour by other ingredients (soy flour, flax flour, and wheat bran) and to analyze the effect of this change on the technological, rheological, and sensorial characteristics of breads. Flaxseed flour (FF), soybeans flour (SF), or wheat bran (WB) was used to replace 50, 100, and 150 g kg−1 of wheat flour (WF) in breads. FF or SF produced a decrease in monounsaturated and SFA and an increase of PUFA in these breads. Furthermore, breads replaced with FF presented considerable increase in the content of n3 FA, while, SF or WB contributed to rise of linoleic and oleic FA, respectively. The substitution percentage increase of FF, SF, or WB to formulation produced changes in the colour, rheological, textural, and technological characteristics of breads. This replacement resulted in improved lipid profile, being breads with 50 g kg−1 SF, the better acceptance, baking features, and enhanced fatty acid profile.

Lower 30 Minute Serum Insulin in Healthy Sprague‐Dawley Rats Consuming Chips from Specific Barley Flour Blends

ABSTRACTConsumption of whole grains such as barley is known to inversely correlate with insulin resistance, type 2 diabetes, and other chronic diseases. However, data from randomized controlled trials in humans have not produced consistent results. Compositional differences between foods produced from different whole grains are likely to be a main reason for these discrepancies. The purpose of this study was to determine if varying barley flour composition achieved through milling influenced the postprandial glucose and insulin response. Specifically, this study aimed to test barley foods in the form of chips with very low hydration, thereby mimicking human snack foods. Fasted rats (N = 39) were randomized to one of four barley treatments, all produced from a single variety, Hordeum vulgare L. ‘CDC Fibar.’ The treatments used were straight‐grade flour (SGF), whole grain flour (WGF), bran flour with high β‐glucan (BF‐BG), bran flour with high insoluble dietary fiber, and wheat flour (WF) as the control. Blood was sampled over 120 min following treatment consumption to measure postprandial glucose and insulin concentrations. Our data showed that although there were no substantial glycemic or insulin effects following one‐time consumption of barley tortilla chips with specific compositions, those rats consuming WGF, SGF, or BF‐BG tended to have lower 30 min serum insulin concentrations compared with those rats consuming WF.

PANELS MADE FROM GIANT REED BONDED WITH NON-MODIFIED STARCHES

Panels were made from Arundo donax L. particles bonded with different non-modified starches as adhesive without chemical additives by hot-pressing at a low temperature (110 oC) and pressure (2.6 N/mm2). The experimental panels were tested for their physical and mechanical properties according to the procedures defined by the European Union (EN) Standard. The microstructure of samples was observed by scanning electron microscopy (SEM). Panels manufactured with potato starch had the highest modulus of rupture and modulus of elasticity, meeting the standard for load bearing (grade P4 for indoor use in dry ambient) (EN 312: 2003). Panels made with corn starch and wheat flour, at a 10% level and three pressing cycles met the standard for general uses (grade P1). Panel bonded with rye bran flour achieved the best internal bond strentgh. The water resistance was poor and needs to be improved.

Profiling of cereal-derived alkylresorcinols with antigungal activity against Fusarium oxysporum

Alkylresorcinols are non-isoprenoid phenolic lipids present in several commercial plants of Poaceae family. In vitro studies on alkylresorcinols have shown to possess antimutagenic, antimicrobial, cardioprotective activities among others. As part of our research on antifungal agents, a chemical characterization focused on alkylresorcinol profiling and quantification by HPLC-ESI-MS and Fast Blue RR-based colorimetric method, respectively, were performed on alkylresorcinol-enriched extracts (AEE) from wheat, corn, oats, barley and wheat bran flours. Several alkylresorcinol were identified in each product, whose common structural feature was the alkenyl side chain. Wheat bran was found to have the highest alkylresorcinol content followed by barley, wheat, oats, and maize flours. In addition, in vitro antifungal assay was performed on each AEE against Fusarium oxysporum. All AEE exhibited dose dependent antifungal activity at different levels. All data were correlated by principal component analysis (PCA). A composition-activity relationship was observed.

Chemical, Rheological, Sensorial and Functional Properties of Gelatinized Corn- Rice Bran Flour Composite Corn Flakes and Tortilla Chips

In the present research, stabilized rice bran (SRB) of an Egyptian variety was used for the preparation of corn flakes and tortilla chips with and without fortification with rich protein sources. SRB was used as 10, 20 and 30% replacements of gelatinized corn flour. Doughs of different blends were evaluated rheologically. Color quality, sensory parameters and proximate composition of the products were assessed. Results showed that the maximum and breakdown viscosity and color quality was affected by the presence of SRB. Some sensory parameters of tortilla chips and corn flakes containing RB showed decline. Percentage protein of 30% SRB corn flakes and tortilla chips that were not fortified with protein-rich sources was 10.57 and 11.2, while that of fat was 3.65 and 23.21; crude fibers were 0.775 and 0.631, and ash was 0.24 and 1.71, respectively. Fortified tortilla chips and corn flakes contain 11.5 and 13.7% protein, respectively. PRACTICAL APPLICATIONS The present research aimed at production of functional foods containing both rice bran and corn flour so as to be marketed.

Effect of Enzymatic Extraction Treatment on Physicochemical Properties, Microstructure and Nutrient Composition of Tartary Buckwheat Bran: A New Source of Antioxidant Dietary Fiber

The effect of enzymatic treatment with amylase and cellulase on Tartary Buckwheat (F. tataricum Gaertn) bran dietary fiber was evaluated by studying its chemical composition, physicochemical property and microstructure. Tartary buckwheat bran flour, obtained from residues of tartary buckwheat processing exhibited high contents of dietary fiber (44.2±0.3%), starch (31.94±0.27%), lipid (5.18±0.14%) and total ash (2.91±0.04%), and a low level of crude protein (3.12±0.11%). The contents of hemicellulose, cellulose and klason lignin were 23.80±0.21%, 17.48±0.25% and 4.06±0.21%, respectively. Total polyphenols and total flavonoids contents were 13.32mg GAE/g and 37.43mg RE/g, respectively. The water holding capacity (WHC) and swelling capacity (SC) were 2.22±0.07 g/g and 2.33±0.10 mL/g. After the extraction process with amylase, the dietary fiber, total polyphenols, total flavonoids contents of crude enzymatic extract were increased to 83.5±0.27%, 27.61 mg GAE/g, 52.14 mg RE/g, respectively. Its WHC and SC also grew up to 2.38±0.12 g/g and 4.67±0.09 mL/g, while the starch content was decreased significantly. The crude enzymatic extract from tartary buckwheat bran was modified by cellulase. After the modification treatment, the increasing proportion of soluble dietary fiber (SDF) against total dietary fiber (TDF) was detected, and its WHC and SC also grew up to 2.58±0.11 g/g and 5.13±0.12 mL/g respectively. By Small angle X-ray scattering (SAXS) analysis, it was also learned that the size of DF particles were decreased, which had a positive correlation with WHC and SC. The SEM photos showed that the modification processing increased the surface area of DF.

Role of carbohydrases on the release of reducing sugar, total phenolics and on antioxidant properties of oat bran

Aqueous solutions of medium oat bran flour were treated with four carbohydrases viscozyme, celluclast, alpha-amylase, and amyloglucosidase, and then extracted with equal volume of methanol. The resulting extracts were examined for their reducing sugar content, total phenolic content (TPC), oxygen radical scavenging absorbance capacity (ORAC), hydroxyl radical scavenging effect, superoxide scavenging activity, and ferrous ion chelating potential. The amount of reducing sugar increased form 2.0% in the control sample to 21.4% in the sample treated with four fungal beta-glucanase units/g of bran. The increase in reducing sugar was also associated with subsequent increase of other extractable compounds. The total phenolic content as measured by Folin–Ciocalteu’s method ranged from 0.50 to 4.80mg of gallic acid equivalents/g of bran, whereas the ORAC values were 14.4–25.4μM of Trolox equivalents/g of bran. All the samples treated with carbohydrases had higher TPC content and higher ORAC values than the control sample (no enzyme treatment). In the hydroxyl radical scavenging assay, except for the alpha-amylase treated sample, all other samples demonstrated a greater inhibition power than the control. These results indicated that pre-treatment of oat bran with cell wall degrading enzymes (i.e. carbohydrases) is a way to increase the amount of extracted phenols as well as the antioxidant properties of oat bran samples.

Properties of Arabinoxylans from Wheat Bran, Shorts and Flour

Arabinoxylans were prepared from bran, shorts and flour, three wheat milling fractions. The yields of bran arabinoxylan (WBAX), shorts arabinoxylan ( WSAX) and flour arabinoxylan ( WFAX) were 8.99%, 7.28% and 1.12% respectively. Sugar composition analysis showed that WFAX contained less non-cellulosic sugars ( 75.56%) compared with WFAX and WSAX. WBAX had the lowest Ara/Xyl ratio compared with WSAX and WFAX. HPSEC analysis showed that WFAX had higher molecular weight compared with WBAX and WSAX, and WBAX had the lowest molecular weight. WBAX, WSAX and WFAX in water solution had higher molecular weight than in 0.5mol/L NaOH and 1.0mol/L NaOH. In 1.0 mol/L NaOH solution, arabinoxylans had the lowest molecular weight compared that in 0.5 mol/L NaOH and distilled water. From the recovery of WBAX, WSAX and WFAX in different solvents, it showed that 1.0N NaOH had good dissolved effect for arabinoxylans, and water heating treatment ( 80°C 2hr, then stirring overnight at room temperature) had poor dissolved properties compared with 0.5 mol/L NaOH and 1.0 mol/L NaOH ( 25°C,2hr)

Effect of blend levels on composite wheat doughs performance made from yam and cassava native starches and bread quality

The effects of refined wheat flour substitution with two native starches from yam tuber and cassava root, and two commercial products, a specialty starch, C*Actistar and a wheat bran flour, at 10%, 20%, 30%, 40% and 60% dry basis, on the rheological properties of dough and bread characteristics, have been examined. In general, during the mixing phase, the substitution of white wheat flour for starch or wheat bran flour had a tendency to modify the flour strength from strong to weak, depending on the nature of the added fraction and the level of substitution. Yam starch and wheat bran flour weakened dough strength to a lesser extent in comparison with cassava starch, and by far, the resistant starch, C*Actistar. In addition, differences in dough expansion appeared among the botanical origins of composite dough and the blend proportions, during the fermentation phase. White wheat flour substitution for yam starch up to 30% or cassava starch up to 20% led to kinetics expansions of resulted doughs close to that of the control, while those of doughs containing C*Actistar starch or wheat bran flour were significantly slower than that of the control, whatever the level of substitution. The baking phase showed that yam starch enriched breads from 10% to 40% of substitution and cassava starch enriched breads from 10% to 30% of substitution gave as bulky loaves as the refined wheat bread. Beyond these concentrations, the resulting breads were less voluminous. Hedonic tests revealed that, 30% yam starch substitution and 20% added cassava starch led to composite breads which met consumer satisfaction on all attributes, as the control.

Determination of zearalenone in botanical dietary supplements, soybeans, grains, and grain products by immunoaffinity column cleanup and liquid chromatography: single-laboratory validation.

The accuracy, repeatability, and reproducibility characteristics of a method for measuring levels of zearalenone (ZON) in botanical root products, soybeans, grains, and grain products were determined by an AOAC single-laboratory validation procedure. Replicates of 10 test portions of each powdered root product (black cohosh, ginger, ginseng), brown rice flour, brown rice grain, oat flour, rice bran, soybeans, and wheat flour at each spiking level (ZON at 0, 50, 100, and 200 microg/kg) were analyzed on 3 separate days. Test samples were extracted with methanol-water (75 + 25, v/v). The extracts were centrifuged or filtered, diluted with phosphate-buffered saline (PBS) containing 0.5% Tween 20, and filtered; the filtrates were applied to an immunoaffinity column containing antibodies specific for ZON. After the column was washed with methanol-PBS (15 + 85, v/v) containing 0.5% Tween 20 and then with water, the toxin was eluted from the column with methanol, and the eluate was diluted with water. The eluate containing the toxin was then subjected to RPLC with fluorescence detection. All commodities that were found to contain ZON at < 10 microg/kg were used for the recovery study. The average within-day and between-days recoveries of ZON added at levels of 50-200 microg/kg ranged from 82 to 88% and from 81 to 84%, respectively, for all test commodities. The total average of within- and between-day SD and RSDr values for all test commodities ranged from 2.5 to 7.3 microg/kg and from 4.6 to 6.2%, respectively. HorRat values were <1.3 for all matrixes examined. The tested method was found to be acceptable for the matrixes examined.

Supplementation of biscuit using rice bran and soybean flour.

The cost of animal protein is increasing every day, thus making it unavailable for most people in developing countries. This unavailability has resulted into looking for other alternatives protein sources. Gradual shift away from fiber in diets calls for development of recipes, formulae and products that would restore the levels of dietary fiber. Snack foods such as biscuits and crackers offer several important advantages including; wide consumption, relatively long shelf life, good eating quality, highly palatable and acceptable in most countries. These characteristics make protein rich biscuits attractive for the research work. Wheat, soybean and rice bran flour blends were used for the formulation of biscuits in these ratios; (100% wheat flour), (70% wheat, 20% soybean, 10% rice bran flours), (50% wheat, 30% soybean, 20% rice bran flours), (30% wheat, 40% soybean, 30% rice bran flours), (10% wheat, 50% soybean, 40% rice bran flours). Width, thickness, spread ratio, sensory attributes (colour, texture, taste, odour and general acceptance), and proximate compositions (protein, fiber content, fat, ash and moisture content) of the formulations were analysed using AOAC standard methods. Widths of the biscuit samples ranged between 36.75 - 43.3 mm. Increase in width were noticed with increase in level of substitution. Similar trend was recorded on spread ratio. However, biscuit thickness decreased with increase in level of substitution. At p ≤ 0.05, most preferred composite sample (wheat 70%, soybean 20%, rice bran 10%) showed no significance difference with control (100% wheat) in general preference of sensory ratings. Sample E (10 % wheat, 50% soybean, 40 % rice bran) was the least generally preferred sample. Proximate compositions of best-rated composite flour biscuit were protein (16.28 ± 0.41%), fiber (1.90 ± 0.17%), fat (12.13 ± 0.67%) and moisture (4.37 ± 0.18%). It is possible to produce biscuit from composite of wheat, full fat soybean and stabilized rice bran from parboiled rice flours. Adoption of this technology of biscuit manufacture will result in production of better protein and fiber enriched biscuit to the ever-increasing number of consumers.

A Novel Medium for the Enhanced Production of Cyclosporin A byTolypocladium inflatum MTCC 557 Using Solid State Fermentation

Cyclosporin A (CyA) produced by Tolypocladium inflatum is a promising drug owing to its immunosuppressive and antifungal activities. From an industrial point of view, the necessity to obtain a suitable and economic medium for higher production of CyA was the aim of this work. The present study evaluated the effect of different fermentation parameters in solid state fermentation, such as selection of solid substrate, hydrolysis of substrates, initial moisture content, supplementation of salts, additional carbon, and nitrogen sources, as well as the inoculum age and size, on production of CyA by Tolypocladium inflatum MTCC 557. The fermentation was carried out at 25+/-2 degrees for 9 days. A combination of hydrolyzed wheat bran flour and coconut oil cake (1:1) at 70% initial moisture content supported a maximum production of 3,872+/-156 mg CyA/kg substrate as compared with 792+/-33 mg/kg substrate before optimization. Furthermore, supplementation of salts, glycerol (1%w/w), and ammonium sulfate (1%w/w) increased the production of CyA to 5,454+75 mg/kg substrate. Inoculation of 5 g of solid substrate with 6 ml of 72-h-old seed culture resulted in a maximum production of 6,480+95 mg CyA/kg substrate.

Simultaneous saccharification and fermentation of wheat bran flour into ethanol using coculture of amylotic Aspergillus niger and thermotolerant Kluyveromyces marxianus

Studies on simultaneous saccharification and fermentation (SSF) of wheat bran flour, a grain milling residue as the substrate using coculture method were carried out with strains of starch digesting Aspergillus niger and nonstarch digesting and sugar fermenting Kluyveromyces marxianus in batch fermentation. Experiments based on central composite design (CCD) were conducted to maximize the glucose yield and to study the effects of substrate concentration, pH, temperature, and enzyme concentration on percentage conversion of wheat bran flour starch to glucose by treatment with fungal α-amylase and the above parameters were optimized using response surface methodology (RSM). The optimum values of substrate concentration, pH, temperature, and enzyme concentration were found to be 200 g/L, 5.5, 65°C and 7.5 IU, respectively, in the starch saccharification step. The effects of pH, temperature and substrate concentration on ethanol concentration, biomass and reducing sugar concentration were also investigated. The optimum temperature and pH were found to be 30°C and 5.5, respectively. The wheat bran flour solution equivalent to 6% (w/V) initial starch concentration gave the highest ethanol concentration of 23.1 g/L after 48 h of fermentation at optimum conditions of pH and temperature. The growth kinetics was modeled using Monod model and Logistic model and product formation kinetics using Leudeking-Piret model. Simultaneous saccharificiation and fermentation of liquefied wheat bran starch to bioethanol was studied using coculture of amylolytic fungus A. niger and nonamylolytic sugar fermenting K. marxianus.

Effects of treated and untreated bran in dough dynamic rheology

Grains of the wheat variety Tajan were milled into straight-run flour and bran. Proximate analysis, farinograph experiments and rheological characteristics were conducted. Two types of bran (hydrothermal treated and untreated) at three levels (0%, 5%, 10%) were added to the parent flour. Proximate analysis and farinograph experiments of these flours were conducted. The effects of adding treated and untreated bran in linear (strain=0.1%) and non-linear limits (strain=1%, 5%, 10%) have been determined by dynamic oscillatory tests. Results show that, in the linear limit, the G′ value for the untreated bran sample is very close to parent flour while the G′ value of treated bran flour is lower than that of parent flour. The same changes occur in G″ values. In the non-linear limit, the G′ values for both treated and untreated bran samples were higher than parent flour while the G″ value for untreated bran samples had no significant difference from the parent flour. Tge loss tangent for untreated bran flour in the non-linear limit was higher than that of the parent flour, while for treated bran flour it is lower than parent flour. It can be concluded that untreated bran weakens the gluten matrix. On the other hand, adding treated bran, to some extent, strengthens the protein matrix.
