Development and Characterization of High-Fiber, Gluten-Free Pasta for Celiac Disease Patients

Celiac disease (CD) is a multi-organ complex autoimmune disorder triggered by a gluten-containing diet in genetically predisposed individuals. The only effective treatment for people with CD is strict, lifelong adherence to a gluten-free diet to reduce severe disease outcomes. Therefore, this study aimed to produce high-nutrition gluten-free pasta by substituting wheat flour with lupin flour, flaxseed flour, rice flour, and corn starch. For this purpose, six gluten-free pasta treatments (T1–T6) were produced with different flour compositions. In addition, inulin, xanthan gum, beta-glucan, and Moringa leaf powder in fixed amounts were added to all treatments. For the proximate analysis, color measurements and sensory evaluation were determined for all treatments. Proximate analysis of our results showed that substituting wheat flour with composite flour blends was satisfactory for producing nutritious pasta products without affecting their quality. Compared to the control group, T6 had a significant increase in fiber (4.68 ± 0.25 vs. 1.24 ± 0.28), lipid (21.99 ± 0.38 vs. 9.32 ± 0.25), protein (13.84 ± 0.30 vs. 13.45 ± 0.51), and ash content (1.65 ± 0.07 vs. 1.28 ± 0.06) of gluten-free pasta. However, the carbohydrate content decreased compared to the control treatment (46.10 ± 0.69 vs. 60.84 ± 0.75). The color measurement evaluation found a significant difference in the lightness (L*), redness (a*), and yellowness (b*) values between the control and all gluten-free pasta treatments. The sensory evaluation of the finished gluten-free pasta treatments and control sample indicated that the quality score for overall acceptability varied widely for different treatments due to individual preferences. Our study concluded that gluten-free pasta with high nutritional value from gluten-free flour is a good alternative product for celiac patients.

Formulating low-fat beef burger with fenugreek seed gum: Impact on texture, chemistry, and sensory characteristics

SummaryCalorie-dense materials like fats and oils can be substituted with hydrocolloids, resulting in wholesome, reduced-fat, or fat-free foods that may exhibit nearly similar quality. Fenugreek seed gum (FSG), with applicable water-holding capacity (574%) and oil-holding capacity (986%) may provide essential fat-like functions. The objective of this study was to explore the impact of FSG at different concentrations (0.05%, 0.25%, and 0.5%) on the physicochemical, textural, and sensory properties of low-fat hamburgers, in comparison to their high-fat counterparts. The reduction in fat content and the inclusion of FSG resulted in a notable increase in fat retention, while there was a slight reduction in moisture retention when compared to the control group. Remarkably, the low-fat formulations containing 0.05% and 0.25% FSG displayed a significant 57% reduction in cooking shrinkage (P < 0.05). Acceptable texture-related attributes (decreased hardness, higher juiciness, and less springiness) were observed for the cooked FSG-treated patties (P < 0.05). Moreover, raw beef patties processed with a high replacement level of FSG showed the lowest yellowness (P < 0.05) with no significant changes in the L* and a* values (P > 0.05). Sensory evaluation revealed no significant difference among all the treatments, but the low-fat formulations supplemented with 0.25% FSG showed the highest score of overall acceptability.

Physicochemical and sensory evaluation of cookies from germinated maize (Zea mays)-kpaakpa (Hildegardia barteri) - blanched plantain (Musa paradisiaca) composite flour

Composite flours are recently manufactured not only to improve the desired functional properties of end products based on them but also to improve nutritional composition. This study is aimed at determining the physicochemical qualities and sensory properties of composite flour cookies. Germinated maize (Zea mays), Hildegardia barteri (“Kpaakpa”), and blanched plantain (Musa paradiciaca) flour were processed into flours and mixed into various blends using a mixture design. Cookies were produced from the composite flours using the creaming method. The physicochemical and organoleptic properties of the cookies were evaluated. The proximate results showed that increasing the level of Hildegardia barteri flour in the mixture enhanced the protein, fat, ash, and crude fiber contents of the cookies. Micronutrient results showed that iron and zinc increased with the high inclusion of Hildegardia barteri flour. The cookies’ physical properties did not significantly deviate from the control sample. The panelists’ mean score for overall acceptability ranged from 2.65 – 7.75 for all of the samples using HMP1 and HMP9 scoring the lowest. Most of the samples had sensory scores above the midpoints and were generally perceived as acceptable by the panelists. Cookies made with 33.3% of each component were most preferable as they were found to be the best in terms of overall quality. The results obtained from this study demonstrate the possible use of the Hildegardia barteri - based composite flours in bakery products up to 50 % level of substitution. This information can be used for designing food processing protocols which will target consumer requirements and overall acceptability.

Solvent retention capacity as a useful tool for quality evaluation of flours produced from Slovak bred wheat varieties

Abstract Wheat varieties (IS Danubius and MS Luneta) bred in Slovakia were assessed for their bakery potential. It was found that flour produced from IS Danubius was characterised by significantly higher level of wet and dry gluten content (30.91 and 20.53 %, respectively) and exhibited higher gluten swelling capacity (29.3 %) in comparison to commercial wheat flour that is usually available in Slovak markets. Solvent retention capacity (solvation in specific solvents) of the tested flours was also determined. The measurements showed that these parameters significantly differ from those determined for commercially available flour, whereas the flour produced from IS Danubius wheat variety had the highest lactic acid retention capacity (124.15 %). Correlation analysis indicated strong positive correlations between solvent retention capacity values and gluten characteristics. Furthermore, it was found that baked rolls prepared from IS Danubius flour showed significantly higher loaf volume compared to commercial wheat flour. This study proves lactic acid retention capacity and sucrose retention capacity as parameters enabling the prediction of gluten network quality in dough and of qualitative parameters of baked goods. From the sensory evaluation resulted that the highest score for overall acceptance was observed in IS Danubius baked rolls, which significantly differs from both MS Luneta and commercial wheat flour.

Cracker snacks have a high potential to enhance nutritional value. crackers made from corn flour fortified with different ratios of freeze-dried banana peel (FDB-peel) or freeze-dried banana pulp (FDB-pulp) or FDB-peel and FDB Pulp. FDB-peel, FDB Pulp, and crackers were analyzed for proximate analysis, vitamins, minerals, sensory evaluation, antioxidant activity, total phenol, HPLC analysis of phenolic compounds, texture analysis, storage stability of crackers, and prevention of rancidity. The highest protein, dietary fiber, and vitamin C are presented in FDB-Peel which is rich in potassium and calcium. Ferulic acid and Sinapic dominated the phenolic profile of the FDB pulp and peel. Crackers sample (F5) which contained 50 % corn flour 25 % FDB-pulp and 25 % FDB-peel showed a significant increase in dietary fiber. The sensory evaluation of F3 which contained 80 % corn flour and 20 % FDB-pulp had a high score of overall acceptability. The total phenolic and antioxidants were increased with the addition of FDB peel and pulp powder in crackers. The peroxide and acid value in crackers was low compared to the control. The FDB-pulp and FDB-peel products contain a great deal of nutritional properties and hence have potential utility for use as functional ingredients in food product development.

Evaluation of rheological, textural, and sensory characteristics of optimized vegan rice puddings prepared by various plant‐based milks

AbstractNowadays, plant‐based milks are being considered as an alternative to dairy milk due to their advantages, such as sustainability, reduced allergenicity, health benefits, and lactose‐free nature. Plant‐based milks are widely used in the preparation of desserts, cheese‐like products, and beverages, among other applications. The aim of the present study was to formulate vegan rice puddings using various commercially available plant‐based milks as a sustainable alternative to dairy milk. For this aim, central composition design was applied to optimize the key processing parameters of the Thermomix®, including temperature (80–90°C), time (6–14 min), and the amount of rice flour (6–10%, w/v), using response surface methodology (RSM). According to the RSM results, the optimum conditions were found to be 90°C for 12.5 min with 6.5% rice flour, as they exhibited minimal phase separation and similar rheological and textural properties to dairy rice pudding. Soya milk pudding had the highest hardness value among the other plant‐based milk puddings, and whole fat milk, soya, oat, coconut, and cow's milks showed the best gel unity, according to the cohesiveness results. Phase separation, an important parameter for storage stability, was not observed during 7‐day storage at 4°C in all groups, except for pistachio milk rice pudding. Rheological results demonstrated that all vegan pudding samples exhibited a gel‐like structure with storage modulus (G′) exceeding loss modulus (G″) values. According to the descriptive sensory evaluation, coconut, oat, and soya milk rice puddings received the highest scores in overall acceptability. Our findings suggest that industrial plant‐based rice puddings have great potential as a novel product that meets the dietary needs of the vegan community by offering acceptable flavor and texture.

ABSTRACT This study evaluated the iron-rich Nutri bar’s effect on iron-deficient females. Iron-rich Nutri-bars made with spinach powder and chickpea flour. The physicochemical profile of the bars was measured. Socioeconomic status and anthropometric data were taken for the effectiveness of the research. This effectiveness trial included 20 girls ages 20 to 25. After that, biochemical tests, including hemoglobin, ferritin, and total iron-binding capacity (TIBC) were conducted. Results showed that the iron-rich Nutri-bars (T3, 6.60) had more moisture than other treatments. T3 protein and fiber composition was 16.90% and 4.30%. In T3, crude fat and ash content were the lowest. All the proximate analyses of incorporated spinach powder and chickpea flour indicated a significant correlation (P > .005). A jury gave treatment T3 the highest score in overall acceptability. Iron and zinc concentrations were 13.2 and 5.9 mg/100 g in T3. Post-assessment height, weight, and body mass index (BMI) indicated a very significant (P > .005) connection compared to pre-assessment (P > .005). Selected young females' hemoglobin, serum ferritin, and total iron-binding capacity were tested biochemically. After the intervention, the experimental group’s mean hemoglobin (HB) was 12.21 ± 1.14 g/dl (P > .005). Increasing patterns support the current study’s iron improvement. Serum ferritin exhibited similarly substantial outcomes. TIBC dropped when iron status increased. Conclusively, iron-rich nutri-bars supplemented with spinach leaf powder and chickpea flour increased iron status in young females.

The pace of modern life of dwellers in big cities worldwide increases the demand for fast food or ready-to-cook meals. Dal curry is a common and popular meal item in Bangladesh, but its long cooking time needs to be reduced to satisfy consumer’s needs. So, this study is aimed at developing and analyzing ready-to-cook mixed dal powder. Samples were prepared with 100% lentil (control), 25% green gram with 75% lentil (S1), 25% black gram with 75% lentil (S2), and 50% of both dal in 1 : 1 ratio with 50% lentil (S3). Compared to mixed dal powder (8 minutes), the lentil dal powder took less cooking time (7.29 minutes). Mixed dal had no significant effect ( p &gt; 0.05 ) on moisture, fat, and ash but affected on protein content. All mixed dal powder samples showed a higher protein content as well as amino acids such as alanine, aspartic acid, cysteine, glutamic acid, histidine, isoleucine, leucine, methionine, and tyrosine compared to the control. In contrast, the control showed the highest amount of arginine, glycine, lysine, proline, serine, and threonine. Control sample showed the highest loose bulk density (0.828 g/ml), tapped bulk density (0.905 g/ml), water absorption index (5.160 g/g), and water solubility index (24.410 g/100 g) than mixed samples. The color was influenced significantly by adding different pulses variety. The flowability of each sample was excellent, as Carr’s index (CI) and Hausner ratio (HR) for all samples were within 0-10% and 1.00-1.11, respectively. Although no significant differences were found, the sample with 50% lentil, 25% green gram, and 25% black gram secured the highest score in overall acceptability. Samples’ total viable count was assessed for up to 6 months, where the values were within the acceptable limit.

Effects of Different Fermenting Agents on Proximate Composition and Sensory Evaluation of Masa - A Fermented Puff Fried Batter

Fermentation improves the shelf life, texture, taste and aroma, nutritional value and digestibility and also lowers the content of antinutrients of fermented meals. This study investigated the effect of different fermenting agents on the quality of masa. The rice grains were sorted, cleaned, washed and soaked, wet milled and fermented separately with baker’s yeast, lactic acid culture (yogourmet) and tsamiyan gaye (citric acid) respectively. The final batter was fried and package for analysis. The different fermenting agent had significant (p&lt;0.05) effect on all parameters measured. Masa fermented with lactic acid bacteria culture (LAB) had the highest value of 9.25% 0.83%, 1.01% and 18.51% for protein, crude fibre ash and fat content respectively while yeast fermented masa had higher respective value of 21.46% and 50.12% for moisture and carbohydrate content. The pH of masa sample is within the r range of 3.76-5.57 and titritable acidity of 0.05-0.17. The sensory evaluation was carried out to assess the acceptability of the masa samples. However, all masa samples were generally accepted but baker’s yeast fermented masa had higher means scores for overall acceptability (7.40). Tsamiyan gaye (citric acid) and LAB culture can be used as an alternative to baker’s yeast for preparation of masa.

Effect of Piaractus brachypomus fish protein hydrolysate on physicochemical, sensory, and storage properties of cookies

The impact of different concentrations of red-bellied pacu fish meat protein hydrolysate (RPMPH) on the physicochemical, sensory, and storage properties of cookies was studied. RPMPH was prepared from red-bellied pacu fish meat by probiotic Bacillus fermentation for 48 h. RPMPH showed 87.48% protein content with DPPH scavenging activity (71.22%), ABTS scavenging activity (90.05%), ferric reducing antioxidant power (278.13 μM TE/g), and Fe2+ chelating activity (65.46%). Cookies incorporated with RPMPH displayed a higher protein content (11.76–14.40%) and in vitro protein digestibility (65.21–96.0%) compared to control (without RPMPH) cookies (P < 0.05). The total dietary fiber content of all cookies ranged from 1.74 to 2.63 g/100 g sample. The control-cookies had a higher diameter (7.0 mm) and spread ratio (8.37%) compared to cookies incorporated with RPMPH (P < 0.05). The cookies incorporated with RPMPH exhibited a slightly higher water absorption index (6.79–7.51%), water solubility index (2.74–2.88%), and hardness (41.36–49.48 N) than the control-cookies. Color of cookies, influenced by incorporation of RPMPH. Further, the cookies incorporated with RPMPH showed slightly higher moisture and water activity compared to control-cookies throughout the storage (P < 0.05). Conversely, cookies incorporated with RPMPH displayed lower free fatty acids, peroxide values, and thiobarbituric acid substances than control-cookies (P < 0.05) throughout the storage period. The cookies with 8% RPMPH exhibited a higher score for overall acceptability and presented a better amount of essential amino acids. The present study suggested that 8% RPMPH can be incorporated into the cookie formulation, enhancing the nutritional profile and storage stability.

Influence of feed moisture content on physical and sensory properties of extruded pure mung bean starch vermicelli

SummaryThe extrusion process was studied to replace the traditional process of making mung bean vermicelli. The physical and sensory properties were studied of pure mung bean vermicelli made using a single‐screw extruder with different feed moisture contents of mung bean starch (35%, 40%, 45% or 50%). The degree of starch gelatinisation, water absorption, cooking loss and diameter of extruded vermicelli increased with increased feed moisture content. The extrusion temperature provided a more transparent vermicelli product at a higher feed moisture content. Compared with the commercial product using the traditional method, the extruded mung bean vermicelli had greater lightness (L*) and yellowness (b*) for the dried vermicelli and greater blueness (b*) for the cooked vermicelli. The tensile strength and elasticity decreased significantly with increased feed moisture content. The extruded mung bean vermicelli was ranked as ‘well satisfied’ by the panellists, especially, the vermicelli with a feed moisture content of 50%, which had the highest score in overall acceptability compared with the other conditions, including the commercial vermicelli. In conclusion, the extrusion method could be applied to produce good quality, pure mung bean vermicelli instead of the traditional method.

Physicochemical Characteristics, Antioxidant Properties and Consumer Acceptance of Greek Yogurt Fortified with Apple Pomace Syrup.

Despite having high polyphenolic phytochemicals and functional components, apple pomace (AP) is often discarded in landfills, leading to pollution. The study aimed to find a sustainable application for AP in Greek yogurt fortified with AP syrup (APS). Physicochemical characteristics and antioxidant properties were analyzed for APS (APS0.00, APS1.25, APS2.50, APS3.75, APS5.00). As the AP content in the syrup increased, moisture content, titratable acidity, and viscosity significantly increased (p < 0.05). The total polyphenols and flavonoid content of APS increased with increasing AP content. In Greek yogurt fortified with APS (APY), reducing sugar content (0.55 mg/mL to 0.71 mg/mL) significantly increased with fermentation time and AP content, whereas pH level (6.85 to 4.28) decreased. The antioxidant activities by DPPH radical scavenging activity, ABTS radical scavenging activity, ferric reducing antioxidant power, and reducing power were also significantly increased with the AP content and fermentation time. In the consumer acceptance test of APY, APY1.25 had significantly high scores in overall acceptance, taste acceptance, and aftertaste acceptance with purchase intent (p < 0.05). The Greek yogurt fortified with APS as functional food had improved antioxidant properties and consumer acceptance, suggesting the possibility of developing sustainable AP products.

Quality Evaluation of Noodles Produced From Blends of Wheat, Unripe Banana and Cowpea Flours

The work determined the quality of noodles produced from wheat, unripe banana and cowpea flour blends. Flour blends were produced from wheat, cowpea and unripe banana flour at the ratios of 100:0:0, 80:10:10, 70:10:20, 60:10:30, 50:10:40 (wheat: unripe banana: cowpea). Noodles were prepared from the flour blends and evaluated for the chemical composition, color, cooking characteristics and sensory properties. Noodles from 100% wheat flour served as control. The cowpea flour contained higher amount of protein while the unripe banana flour and wheat flour had higher levels of carbohydrate than the cowpea flour. The wheat flour had higher sodium, calcium, magnesium and phosphorous contents than the other flours, which were closely followed by those of the unripe banana flour. The moisture contents of the noodles varied from 9.15-11.25%. The ash contents of the noodles ranged between 1.03 and 1.80%.The crude fiber, fat and carbohydrate contents of the noodles increased with the level of cowpea flour in the noodles. The energy contents of the noodles ranged from 383.39-422.31Kcal/100g. The cooking time decreased from 10.50 min in wheat flour noodles to 7.50 min in the noodle containing 40% cowpea flour. However, the cooking loss and weight increased as the amount of cowpea flour in the noodles increased. The wheat flour noodles were rated higher for color, taste and overall acceptability but not for flavor and mouthfeel. The score for overall acceptability of the wheat flour noodle was 8.60 while those of the composite flour noodles containing 10 and 20% cowpea flour were 8.15 respectively on 9-point Hedonic scale. It is concluded that noodles could be produced from 70% wheat, 20% cowpea and 10% unripe banana flour blends without affecting the qualities of the noodles.

STUDY ON THE EFFECTIVENESS OF ADDING SOME PLANT EXTRACTS WITH BHT ON MEAT QUALITY OF LAMB PATTIES DURING CHILLING STORAGE

This experiment was aimed to evaluate and compare the effects of adding natural extracts (clove, Mentha and thyme) with synthetic BHT on some physiochemical, microbial, and sensory characteristics of lamb patties stored at 4 Cº for 12 days. Results indicated that there’s a steady rise (P&lt;0.01) in oxidative rancidity, microbial and pH with the increasing time of storage. Also, a significant (P&lt;0.01) reduction in TBA, microbial and pH was observed in patties treated with clove, thyme, mentha and BHT as compared with untreated samples. It was found that adding natural extracts is more effective in inhibiting microbial count than did BHT. The highest score of overall acceptability was noticed in patties blended with thyme and mentha, and the lowest was recorded in control samples

Bio-Converted Spirulina for Nutraceutical Chewing Candy Formulations Rich in L-Glutamic and Gamma-Aminobutyric Acids

This study aimed at evaluating changes of microalgae Spirulina during its fermentation with Lactiplantibacillus plantarum No. 122 strain, and further at incorporating Spirulina bio-converted for nutraceuticals rich in L-glutamic (L-Glu) and gamma-aminobutyric acids (GABA) into sucrose-free chewing candy (gummy) preparations. Fermented Spirulina had higher b* (yellowness) coordinates than untreated (non-fermented), and fermentation duration (24 and 48 h) had a statistically significant effect on colour coordinates. The highest contents of L-glutamic and gamma-aminobutyric acids (4062 and 228.6 mg/kg, respectively) were found in 24 and 48 h-fermented Spirulina, respectively. Fermentation increased the content of saturated fatty acids and omega-3 in Spirulina, while monounsaturated fatty acids and omega-6 were reduced. The addition of fermented Spirulina (FSp) significantly affected hardness, decreased lightness and yellowness, and increased the greenness of chewing candies. All chewing candy samples (with xylitol) prepared with 3 and 5 g of FSp and 0.2 µL of Citrus paradise essential oil received the highest scores for overall acceptability, and the highest intensity (0.052) of emotion "happy" was elicited by the sample group containing xylitol, agar, ascorbic acid, 3 g of FSp, and 0.1 µL of Mentha spicata essential oil. As an outcome of this research, one may conclude that fermented Spirulina has significant potential as an innovative ingredient in the production of healthier sucrose-free nutraceutical chewing candies.

Production of Biscuit Mixed with Date Powder

Dates (Pheonix dactylifera L.) are high in essential nutrients and have potential health benefits whilst biscuits form the most popular snacks among all ages from children until the elderly in Malaysia. Hence, it is worth developing biscuits mixed with date powder which are easy and light to carry around, tasty, ready and easy to be consumed. The main objective of this study is to develop the best formulation for biscuit mixed with date powder (DP). DP was used at 10%, 20%, 30%, 40% and 50% replacement levels of sugar for the production of biscuits. Biscuit made from 100% sugar was used as control. Results of hedonic sensory test showed that F3 biscuit with incorporation of 30% DP had the highest mean score for overall acceptance of 7.20, thus placing F3 biscuit as the best formulation. Addition of DP more than 30% showed a significant difference (p &lt; 0.05) on the sensory quality of the biscuits. Therefore, the addition of date powder should not exceed 30%. The physical analysis revealed that F3 biscuit had a darker and more red colour than the control besides having a softer texture. Meanwhile, proximate analysis showed that F3 biscuits contained 3.60% moisture, 0.84% ash, 0.30% crude fiber, 7.57% protein, 21.90% fat, 65.80% carbohydrate and energy value of 491.13 kcal. The addition of DP significantly increased the moisture, ash and crube fiber content (p &lt;0.05) in the biscuits but showed no significant decrease (p&gt; 0.05) for the protein content than the control. Microbiological tests proved that total microbial count of F3 biscuits which stored for six weeks is less than the maximum count as stated in the literature. In conclusion, DP has the potential to be used as a sweetener and for fibre enrichment purpose in biscuit production.
