In this study, the influence of walnut flour in biscuit production was studied. Biscuits were made from blends of whole wheat with walnut flours and were assessed for quality attributes and storability. Walnut was blended with whole-wheat thus: B (2%:98%); C (4%:96%); D (6%:94%); E (8%:92%) and F (10%:90%), while plain whole wheat flour served as control (Sample A). The biscuits were baked in the oven operated at 1800C for 20-30 minutes, cooled, packaged, stored for eight weeks, and analysed for physicochemical, microbial and sensory properties using standard methods. The results revealed that the proximate composition of the samples during storage were as follows: protein, moisture, ash, crude-fat, crude-fibre and carbohydrate values ranged thus: (9.30-14.26%), (10.28-12.06%), (2.20-2.92%), (13.24-16.66%), (0.69-1.17%) and (53.60-61.47%) respectively, with better nutrient stability in the treated samples when compared to the control. The colour varied with increasing substitution, while the essential amino acids were higher in the walnut-supplemented samples. The microbial load of the control was higher than those of the treated samples, due to high antioxidant activity of walnut. Sensory evaluation revealed that biscuit sample having 2% walnut flour was most preferred. Keywords: Whole wheat flour; walnut; proximate composition; antioxidant properties; shelf life.

The demand for food products with functional attributes is on the increase worldwide. The present study was aimed at evaluating the effect of supplementing whole wheat flour with 0, 10, 20, 30, 40 and 50% whole green plantain flour on pasting properties of the flour blends, proximate composition, minerals and sensory characteristics of crackers made from the blends. The 100% whole wheat flour served as the control sample. The result showed that the peak viscosity (PV), trough viscosity (TV), breakdown viscosity (BDV), final viscosity (FV) and setback viscosity (SBV) were significantly affected by the level of plantain flour substitution. The 20% plantain flour substitution level recorded the minimum PV (264.00RVU), TV (248.00RVU), FV (531.00RVU) and SBV (263.00RVU) while the 50% plantain flour substituted blend recorded the highest PV (362.00RVU), TV (328.00RVU) and FV (603.00RVU). The control sample recorded the highest SBV (312.00RVU) and least BDV (3.00RVU). The peak times for all the blended samples were the same (7 min) while the time for the control sample was 5 min. There was insignificant difference (P>0.05) in the pasting temperature which ranged from 91.30 – 92.80oC. The crude protein, fat and calcium contents progressively decreased while the ash, crude fibre, carbohydrate, K, Mg, Fe and Zn contents in the prepared crackers progressively increased with increase in the proportion of plantain flour substitution. Cracker prepared from the blend of 80% whole wheat and 20% whole green plantain flours was the most preferred by the sensory evaluation panellists in terms of taste, texture and overall acceptability. It is evident from the study that acceptable crackers of enhanced nutritive value could be produced from blend of 80% whole wheat and 20% whole green plantain flours. The use of flour from unpeeled plantain as ingredient in cracker production would eliminate waste generation and its associated environmental problems.

Background. Extensive milling processes have deprived wheat flour from essential nutrients. Objective of the current study was to assess the nutritive quality of commercial wheat flour (soft flour/SF) through analyses of proximate composition and functional properties as well as quantification of benzoyl peroxide (BP; added as bleaching agent in the SF). Methods. Test samples included commercial soft flour samples purchased from the local supplier from different flour mills (with additives) and a control sample without additives was prepared by grinding the seeds harvested from wheat crop grown in the experimental field of University of Agriculture, Faisalabad, under optimized field conditions without any fertilizer and insecticide. Benzoyl peroxide and Benzoic Acid quantification was performed through High Performance Liquid Chromatography Results. Results when compared with the whole wheat flour (WF; never received additives) indicated that SF had lesser fiber, protein and ash contents, whereas, higher damaged starch, fat, gluten and bulk density. A parallel experiment under selected conditions (temperature, time and solute concentration) showed dissociation of BP into BA soon after the exposure. Observed BA range (13.77 mg/g after 16hrs) in SF and exposure level assessment (44.3±1.36 mg/kg/BW) showed higher intake of BA on the consumption of SF. Results revealed superiority of WF over SF in nutritive qualities as well as free of toxicants such as BA.

Purpose The study aims to design metabolic syndrome (MetS) ingredient mix with optimum amino acid makeup using key foods with reported functional properties and study the efficacy of this mix to alleviate the symptoms of MetS among adult men and women with MetS. Design/methodology/approach In total, 25 MetS-specific ingredient mixes that included wheat flour, common legumes, fenugreek and flaxseeds were formulated by correcting their amino acid score. The suitability of these mixes was tested for the preparation of chapati (an unleavened Indian bread). Owing to its highest lysine content, the ingredient mix of whole wheat flour, oat flour, soybean, flaxseeds and fenugreek seeds was selected for the 12-week supplementation trial among patients with MetS. Findings The sensory scores of chapatis made using nine ingredient mixes was comparable with those of chapati made from whole wheat flour (control). The test chapatis had a significantly (p = 0.05) higher protein, ash, fibre and fat content, and lysine was also higher (591-1,006 mg/100 g) than the control chapatis (314 mg). Positive and significant changes in the anthropometry, body composition, fasting blood glucose levels, blood pressure and lipid profile of the patients with MS was seen after consumption of the selected ingredient mix. Originality/value Keeping in view the traditional vegetarian Indian meals which usually take care of including foods from different sources to improve their protein quality, the concern for providing protein quality to prevent metabolic abnormalities is significant for a large lacto-vegetarian population in India which depends on plant foods for obtaining essential amino acids. Obtaining optimum protein quality from meals along with maintaining a physically active lifestyle may help people have the appropriate fat to lean mass proportion which may have a protective role against MetS.

Composite flours are used for bakery products to improve the nutritional value and reduce the reliance on wheat importation. The present study was aimed at assessing the effect of supplementing whole wheat flour with acha and red kidney bean flours on the physical properties, proximate composition, mineral and sensory characteristics of biscuits made from the blends. Blend ratios used were 100:00:00 (T1, control sample), 75:25:00 (T2), 75:00:25 (T3) and 50:25:25 (T4) (whole wheat: acha: kidney bean flour). The result showed that all the parameters varied with the composition of flours in the blends. The biscuit weight, diameter, thickness and spread ratio ranged from 16.32 to 19.08g, 4.02 to 4.40cm, 0.69 to 0.78cm and 5.33 to 6.38 respectively. Incorporation of kidney bean flour in the blends led to the reduction in spread ratio of the biscuit. The protein, fat, ash, crude fibre and carbohydrate contents in the biscuits ranged from 11.73 to 15.20%, 16.34 to 17.95%, 1.52%, to 1.73%, 1.65 to 1.80% and 63.36 to 68.70% respectively. Samples T3 and T4 with kidney bean flour incorporation had higher protein, dietary fibre and lower carbohydrate contents than samples T1 and T2 with no kidney bean flour incorporation. The calcium, potassium, magnesium, iron and zinc contents ranged from 36.14 – 45.72mg/100g, 105.40 – 128.72mg/100g, 29.60 – 46.81mg/100g, 3.89 – 5.12mg/100g and 2.01 –3.51mg/100g respectively. Incorporation of kidney bean flour enhanced the calcium, magnesium and iron contents in the biscuits. Sensory mean score values showed that samples T3 and T4 were the most preferred samples in terms of overall acceptability as their values were not significantly (p>0.05) difference from each other. It is evident from the study that acceptable biscuits of improved nutritional value and high dietary fibre content could be produced from whole wheat flour supplemented with acha and kidney beans flours. This will increase the utilization of these locally grown crops and reduce wheat importation into the country. The high fibre biscuit will also possess several health benefits.

The present study was aimed at utilizing soursop flour for the production of chin-chin. Soursop (SS) was processed to flour. Chin-chin was prepared from blends of wheat and soursop flours using 90:10, 80:20, 70:30, 60:40, 50:50 of wheat flour to soursop flour (SSF), and 100% wheat flour as control. Proximate and sensory analysis of the chin-chin was determined using standard methods. The samples were also stored for 3 weeks and evaluated at weekly intervals for total bacterial and fungal counts. Proximate composition of the chin-chin revealed a significant (p<0.05) increase in ash (0.42-0.96%), fat (33.31-39.29%), crude protein (5.32-7.94% protein), crude fibre (0.95-1.12%), and moisture content (4.85-7.65%) with a decrease in carbohydrate content (55.14-42.94%) as substitution of soursop flour increased. Energy content decreased as substitution of soursop flour increased, but beyond 30%, level, the energy content was observed to increase significantly. Substitution of soursop flour with wheat flour at the level of 10% compared favorably with the control sample suggesting that acceptable chin-chin could be produced at SSF substitution of up to 10%. The samples presented adequate microbiological conditions after storage of 3 weeks with counts ranging from 5.20×103-7.00×104cfu/g and 4.00×104-6.00×104cfu/g, for total bacterial and fungal counts, respectively. The study therefore showed that soursop can be utilized for the development of chin-chin with improved nutritional value over 100% wheat flour thereby serving as a nutritious household food which will help address the problem of protein-energy malnutrition.

Two types of buckwheat flour - non-treated (NBF) and autoclaved (TBF) were used for the enrichment of whole wheat tagliatelle (control sample) at the level of 10-30% and the produced tagliatelle samples (dry and cooked) were examined in terms of mineral and phytic acid (PA) content. Both NBF and TBF possessed significantly higher (p < 0.05) content of all investigated minerals compared to whole wheat flour (WWF), but significantly lower (p < 0.05) PA content. Cooked NBF-containing tagliatelle possessed significantly higher (p < 0.05) content of Mg, Zn, Mn and Fe compared to the cooked control sample, while mineral content of cooked TBF-containing tagliatelle samples was not significantly different from the control. Autoclaving significantly reduced (p < 0.05) PA content of cooked TBF-containing tagliatelle samples compared to cooked NBF-containing tagliatelle samples and the control sample. The mineral bioavailability defined through molar ratio of mineral to phytate was slightly improved in buckwheat-containing tagliatelle samples, but it still remains at low level. Regarding all results, the enrichment of whole wheat tagliatelle with NBF at higher levels of substitution (20-30%) resulted in significant increase in mineral content and bioavailability.
