The feasibility of partially substituting wheat flour with pawpaw seed (WFPS) flour in bread formulation was investigated. Matured, ripped pawpaw fruits were washed, and the seeds were collected, extracted, dried and milled. Different proportions of wheat and pawpaw seed flour with increasing level of pawpaw seed flour at 0, 2.5, 5, 7.5, 10 and 12.5 % addition in wheat were prepared. Control sample was 100 % wheat flour and its bread. The physical properties of breads and alveograph properties of dough blends were determined. Also, the mineral and anti-nutritional contents of the bread samples were determined using standard procedures. The GENSTAT Statistical Software (version 17.0) was used for data analyses. Physical properties of the bread samples significantly (p<0.05) decreased in oven spring (5.49-2.39 cm), loaf volume (1022.50-901.60 cm3) and specific volume (4.09-3.14 cm3/g) but increased in loaf weight (250.20-288.50 g) with increased pawpaw seed flour addition. Values for dough maximum pressure (91.00-109.50 mm), extensibility (80.50-54.50 mm) and baking strength (255.00-237.50 ×10-4joules/g) significantly (p<0.05) decreased while the ratio of resistance to extensibility increased (1.36-1.66) with increased seed flour addition. The result of the mineral analysis of the breads showed significant (p<0.05) increase in all the mineral parameters determined. High values were recorded in magnesium (143.00-182.50 mg/100g), calcium (252.60-342.60 mg/100g) and phosphorus (73.50-127.30 mg/100g). The anti-nutritional contents of the breads significantly (p<0.05) increased as the level of pawpaw seed flour substitution increased. Tannins, oxalate, Phytate, and Trypsin inhibitor ranged from 1.76-2.68 mg/100g, 0.06-0.28 mg/100g, 0.06-0.29 mg/100g and 1.28-9.71 TIU/100g respectively.

Aim: The aim of this study is to produce flour from different blend ratio of water yam and cowpea and determination of the physico chemical properties of the snacks produced from the flour blends. Introduction: Snacks are something consumed occasionally for pleasure rather than for nutritive purpose. They are mainly produced by wheat flour. Wheat flour, the main ingredient for production of snacks are imported and thus, the cost of importation of wheat flour eat deep into the Nigeria economy and has placed a considerable burden on the foreign exchange reserve, in the long run causes increase in wheat products. Furthermore, over consumption of wheat products leads to celiac disease associated with immunological disease of the upper intestine triggered by the ingestion of gluten containing cereals. Production of alternative flour to wheat flour can be a welcome idea. Cereal has high nutritional value and it has an appreciable protein content. Study Design: The physico chemical analysis was carried out at the biochemistry laboratory of National Root Crop Research Institute Umudike. Methodology: The water yam (Dioscorea alata) and cowpea (Vigna unguiculata) flours were prepared and they were used for water yam/ cowpea blend at different ratio of (ie 100%:0, 90:10, 80:20, 70:30, 60:40 and 50:50). The 100% water yam was the control sample. Functional properties and proximate composition of the samples were determined. Results and Discussion: According to the result generated from the sensory evaluation, it was discovered that yam/ cowpea blend in the ration of 50:50, 60:40 and 70:30 were more acceptable than the other samples. This can be related to the high content of cowpea in the samples. Conclusion: The yam /cowpea blend in the concentration of 50; 50 was more preferred than the other samples by the panelist.  As a means of nutritional balance yam fortified with cowpea can boost the protein intake of population consuming yam as its main staple.

Исследовано влияние добавки микроводоросли спирулины в рецептуру хлеба из пшеничной муки, обогащенного обойной мукой из зерна ячменя сортов Гранал 32 и Нудум 95 и тритикале сорта Цекад 90, на показатели его качества. Размолотую до порошкообразного состояния спирулину в количестве 0,5 к массе муки вносили при замесе теста в три опытных образца: пшеничный хлеб, хлеб Гранал и Ясень , рецептуры которых были разработаны ранее. В качестве контрольного образца был хлеб из пшеничной муки высшего сорта без добавок. Лабораторную выпечку образцов хлеба проводили в соответствии с методикой госкомиссии по сортоиспытанию на лабораторном хлебопекарном оборудовании. В результате определения органолептических и физико-химических показателей качества готовой продукции установлено, что добавка спирулины к пшеничной муке повышает пористость мякиша хлеба и увеличивает его объем до 546 см3, что на 18 см3 больше, чем в контрольном образце. Достаточно высокий объем 494 см3 имел образец хлеба, в рецептуру которого входит ячменная мука с добавлением спирулины. Внесение спирулины в рецептуру существенно не повлияло на показатели влажности (4346) и кислотности хлеба, которые в опытных образцах соответствуют нормативам ГОСТ 2698786 на хлеб из пшеничной муки. Самую высокую общую оценку 4,2 балла по пятибалльной шкале получил образец хлеба с добавлением к пшеничной муке порошка спирулины. The effect of the addition of spirulina microalgae in the formulation of bread from wheat flour enriched with wholemeal flour from barley grain varieties Granal 32 and Nudum 95 and triticale varieties Tsekad 90, on the indicators of its quality has been studied. Spirulina ground to a powdered state in an amount of 0,5 by weight of flour was introduced when kneading the dough into the formulations of three samples: wheat bread, bread Granal and Yasen , the formulations of which were developed earlier. Bread from wheat flour of the highest grade without additives was as a control sample. Laboratory baking of bread samples was carried out in accordance with the methodology of the state Commission for variety testing on laboratory baking equipment. As a result of the determination of organoleptic and physico-chemical indicators of the quality of the finished product, it was found that the addition of spirulina to wheat flour increases the porosity of the bread crumb and increases its volume to 546 cm3, which is 18 cm3 more than in the control sample. A sample of bread, the formulation of which includes barley flour with the addition of spirulina, had a sufficiently high volume 494 cm3. Adding spirulina to the formulation did not significantly affect the moisture content (4346) and acidity of bread, which in the prototypes correspond to the standards of GOST 2698786 for bread made of wheat flour. A sample of bread with spirulina powder added to wheat flour had the highest overall score 4б2 points on a five-point scale.

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.

The nutrient composition and the acceptability of biscuit from composite flours of wheat, Bambara groundnut (Vigna subterranea), Ground bean seed (Macrotyloma) and Moringa seed (Moringa oleifera) were evaluated. Bambara groundnut (Vigna subterranea), Ground bean seed (Macrotyloma) and Moringa seed (Moringa oleifera) were dried, and processed into flour. The flour blends developed was used as a substitute for wheat flour as composite flour. The resulting mixtures were then used to produce biscuits at different ratios of wheat flour to flour blends; 100:0, 90:10, 80:20 and 70:30 level of the flour blends. The pasting properties, proximate composition, minerals, physical (spread ratio, weight, thickness and colour) and sensory properties of the composite biscuit were evaluated. The pasting properties of the flours showed that pasting temperature ranged from 68.50°C - 70.0°C and the peak viscousity range from 101.17 RVU – 207.17 RVU, while Break down (43.0 RVU) was highest in 90% wheat: 10% (Bambara- groundnut-ground bean seed- moringa seed flour) (WFF1). The protein content increased from 12.50% in the control (100% wheat flour) to a range of 14.40% - 16.19% in the biscuits; crude fibre decreased from 2.83 to 2.40 - 1.84%, ash content increased from 1.26% to a range of 1.53 - 2.01%, while carbohydrate and energy value reduced from 69.20 to 65.54 - 63.36% and 384.04 Kcal/100 g to 391.34 - 391.55 Kcal/100 g respectively. As the ratio of blends level increase, the thickness, diameter and weight increased but the spread ratio decreased. In conclusion incorporation of bambara groundnut, ground bean seed and moringa seed flour blends played important role in enhancing the nutritional properties of biscuits through improving their protein content, energy value and mineral elements especially calcium and potassium.

В России наблюдается повышенный интерес к продуктам питания, включающим нетрадиционное сырье. Спрос на продукты с добавкой семян конопли (Cannabis sativa L.) обусловлен их питательной ценностью и низкой аллергенностью. Исследованы химические и физико-химические показатели пшенично-конопляной муки, полученной из помольной смеси зерна яровой пшеницы сорта Радмира и семян конопли сорта Сурская в соотношении соответственно 95 : 5, 92,5 : 7,5 и 90 : 10%. В качестве контрольного образца была пшеничная мука без добавок. Размол помольных пшенично-конопляных смесей различного соотношения и зерна пшеницы проводили на мельницах лабораторного помола (МЛП-4) с нарезными (драные системы) и микрошероховатыми вальцами (размольные системы). Исследование химических и физико-химических свойств образцов пшенично-конопляной и пшеничной муки проводили на инфракрасном анализаторе SpectraStar 2500 XL. Установлено, что добавление семян конопли в помольную смесь существенно снижает выход пшенично-конопляной муки по сравнению с выходом пшеничной муки (при добавке 5–7,5% семян конопли выход снижается на 4,3–4,4%, а при добавке 10% семян конопли – на 10,6%), однако повышается содержание жира и белка во всех потоках пшенично-конопляной муки, полученной как с драных, так и с размольных систем. По сравнению с содержанием жира и белка в муке из зерна пшеницы, составившим 1,12 и 11,57% соответственно, при добавлении 5% семян конопли в помольную пшенично-конопляную зерновую смесь средневзвешенное содержание жира в пшенично-конопляной муке составило 3,76%, а содержание белка – 12,74%, при добавлении 7,5% конопли в помольную смесь средневзвешенное содержание жира в пшенично-конопляной муке составило 4,35%, а белка – 12,7%, при добавлении 10% конопли в помольную смесь средневзвешенное содержание жира в пшенично-конопляной муке составило 4,97%, а содержание белка – 12,4%. Повышение содержания жира и белка в пшенично-конопляной муке будет способствовать повышению пищевой ценности хлебобулочного изделия из нее. Increased interest in food products, including non-traditional raw materials, is observe among the population of Russia. The demand for products with the addition of hemp seeds (Cannabis sativa L.) is due to their nutritional value and low allergenicity. Chemical and physico-chemical parameters of wheat-hemp flour obtained from a grind mixture of Radmira spring wheat grain and Surskaya hemp seeds in the ratio: 95 : 5, 92,5 : 7,5 and 90 : 10%, respectively, were investigated. Wheat flour without additives was use as a control sample. Grinding of grind wheat-hemp mixtures of various ratios and wheat grains was carried out in laboratory grind mills with rifled (torn systems) and micro-roughened rollers (grinding systems). The study of chemical and physico-chemical properties of wheat-hemp and wheat flour samples was carried out on the SpectraStar 2500 XL infrared analyzer. It was found that the addition of hemp seeds to the grind mixture significantly reduces the yield of wheat-hemp flour compared with the yield of wheat flour (with the addition of 5–7,5% of hemp seeds, the yield decreases by 4,3–4.4%, and with the addition of 10% of hemp seeds – by 10,6%), however increases the fat and protein content in all streams of wheat-hemp flour obtained from both torn and grinding systems. Compared with the fat and protein content in wheat flour, which amounted to 1,12 and 11,57% respectively, when adding 5% hemp to the wheat-hemp grain mixture, the weighted average fat content in wheat-hemp flour was 3,76%, and the protein content was 12,74%, when adding 7,5% hemp to the grind mixture, the weighted average fat content in wheat-hemp flour was 4,35%, and protein – 12,7%, and when adding 10% the weighted average fat content in wheat-hemp flour in the grind mixture was 4,97%, and the protein content was 12,4%. An increase in the fat and protein content in wheat and hemp flour will contribute to an increase in the nutritional value of a bakery product made from it.

The study was carried out to demonstrate the effect of walnut flour enhancement on the physical, nutritional, and sensory quality of bread. Walnut flour was prepared by soaking, deshelling, oven drying, and sieving whole walnuts. The wheat flour was supplemented with walnut flour by 0, 20, 30, 40, and 50% of the total amount. Standard procedures were taken to estimate the proximate composition of wheat and walnut flour and bread samples. A comparison between the control and supplemented bread was made, where the physical characteristics (weight, volume, and specific volume) and sensory quality were checked. The enhanced bread, where the percentage was between 20 and 50%, appeared to have a significant increase in protein, fat, linoleic acid, and α-linolenic acid and a decrease in carbohydrate and fibre values. Increased walnut flour replacement showed that physical properties, loaf volume and specific loaf volume, have declined. The sensory attributes between the unsupplemented and supplemented bread showed major differences. As an outcome, substituting 30% walnut flour gave the best overall quality of bread acceptability.
