Sorghum (S. bicolor) collected from Dhankuta district was used for malting. Sorghum was steeped for 12 hours at Relative humidity of 70±5% and germinated at room temperature (28±3°C) with repeated change of water at interval of every 8 hours for 2, 3,4,5,6 and 7 days. The germinated samples of each day were taken for kilning at the temperature scenario of 50-55°C until moisture reaches to 23%; 70-75°C until moisture reaches to 12%; and 90-95% until moisture reaches to 3-5%. The result of enzyme activity determination showed that the sorghum germinated for 3 days has the higher enzyme activity of 27.39 units per gram dry matter. Proximate analysis of malted and unmalted flour showed significant different (p<0.05) in fat, ash, reducing sugar and crude fiber content. Likewise calcium and iron content of malted flour was significantly increased (p<0.05) than that of unmalted one with subsequent decreased (p<0.05) in their binder oxalate and phytate respectively. The sorghum of higher enzyme activity was then used to prepare the biscuit. Malted sorghum and wheat flour was blended in the following ratios: samples A; 30: 70, sample B; 50:50, sample C; 60:40, sample D; 0:100. The organolaptic test shows the significant difference (p<0.05) between these samples in terms of flavor and test. The mean sensory score was found to be higher for sample C. This suggests that the malted sorghum flour can be used for the preparation of biscuit upto 60% (w/w) of wheat flour without alteration in texture, crispiness, appearance and overall acceptability.Sunsari Technical College Journal 2015, 2(1):33-37

The objective of this work was to study the effect of replacing a selected wheat flour for defatted soy flour, pea flour and whey protein concentrate on both dough rheological characteristics and the performance and nutritional quality of bread. A mixture design was used to analyze the combination of the ingredients. The optimization process suggested that a mixture containing 88.8% of wheat flour, 8.2% of defatted soy flour, 0.0% of pea flour and 3.0% of whey protein concentrate could be a good combination to achieve the best fortified-bread nutritional quality. The fortified bread resulted in high protein concentration, with an increase in dietary fiber content and higher calcium levels compared with those of control (wheat flour 100%). Regarding protein quality, available lysine content was significantly higher, thus contributing with the essential amino acid requirement.

Supplementation of wheat flour with soy flour (full fat and defatted) at 5, 10, 15 and 20% levels was carried out to test the effect on physico-chemical, sensory, nutritional evaluation and shelf life of breads. Adding 10% of soy flour (full fat and defatted) produced breads with good baking and organoleptic characteristics. However, at 15 and 20% levels they were less acceptable. The better breads were further investigated for various nutritional parameters and shelf life. Full fat and defatted soy flour (10%) supplemented bread exhibited 13.66 and 13.81% protein, and 3.02 and 3.05 g/100 g protein total lysine contents as compared to control (wheat) bread (11.47% protein and 2.36 g/100 g protein total lysine). Other nutrients are also increased in supplemented breads as compared to wheat bread. However, for storage, defatted soy supplemented bread exhibited better shelf life than the full fat version.

Cookies are a popular confectionery product with a unique texture and taste, long shelf life and a relatively cheap price; therefore, it is a widespread snack among people of all generations. Nevertheless, cookies are usually made of wheat flour and most formulations are highly caloric and have a low fiber content. Soy flour is an excellent source of proteins, fibers, vitamins and minerals and it is being considered as a great supplement to wheat flour because it increases nutritive characteristics of the final product. By their digestibility and amino acid content, soy proteins are very similar to proteins derived from animals. They also contain many essential amino acids, which are deficient in most of the cereals. The purpose of this work was to determine the effect of soy flour on quality of cookies. Wheat flour was supplemented with 35% of soy flour (full-fat toasted, low-fat toasted, defatted lightly toasted, toasted and soy protein concentrate). The supplementation of wheat flour with soy flour had affected nutritive value and sensory characteristics of cookies.

Supplementation of soy (full fat and defatted) and barley flours to wheat flour at 51 10, 15 and 20% levels were carried out to see their effect on physico-chemical and nutritional properties of blends for bread making. The gluten content and sedimentation value of flour blends decreased and water absorption capacity increased with increase in the level of soybean and barley flour separately and in combinations to bread flour. All the blends at 20% levels were found nutritionally superior but breads prepared from them found organoleptically unacceptable. However, addition of 15% barley flour, 10% full fat soy flour, 10% defatted soy flour, 15% full fat soy flour + barley flour and 15% defatted soy flour + barley flour to wheat flour not only increased the total protein, glutelin (protein fraction), total lysine, dietary fibre and β-glucan contents of cereal-pulse blends for bread making, but could also produce a product of acceptable quality.

Исследовано влияние добавки обезжиренной соевой муки на потребительские свойства пшеничного хлеба. Выбор в качестве обогащающей добавки обезжиренной соевой муки, получаемой из высокопротеиновых шротов, обусловлен более высоким содержанием в ней белков, клетчатки и минеральных веществ по сравнению с пшеничной мукой. В исследованиях за основу взята рецептура пшеничного хлеба из обойной муки, в которую для улучшения вкуса и запаха изделия добавили измельченную лимонную цедру, молотый черный перец и тмин, контрольный образец. В опытные образцы, изготовленные по той же рецептуре, взамен 20 и 30 пшеничной муки добавляли соевую обезжиренную. В готовых образцах хлеба определяли органолептические и физико-химические показатели, пищевую ценность и аминокислотный состав белков. Установлено, что образцы хлеба с добавкой обезжиренной соевой муки имеют насыщенный сладковатый запах и вкус с оттенком внесенных добавок лимонной цедры, тмина и черного перца. По физико-химическим показателям массовой доле влаги, кислотности и пористости образцы хлеба с добавлением соевой муки практически не отличаются от контрольного образца. Образцы хлеба с добавлением 20 и 30 обезжиренной соевой муки имеют более высокую пищевую ценность, чем образец хлеба без добавки, поскольку содержат больше: белковых веществ в 1,7 и 2 раза соответственно, клетчатки на 5080, минеральных веществ на 1530 и имеют более низкое содержание крахмала: в хлебе из пшеничной муки 41,3, в образцах с добавкой 20 и 30 обезжиренной соевой муки 30,0 и 37,3 соответственно. Внесение обезжиренной соевой муки в рецептуру хлеба повышает содержание незаменимых аминокислот в составе белка. Поэтому использование продуктов переработки сои в хлебопечении может быть рассмотрено как одно из направлений улучшения потребительских свойств хлебобулочных изделий. The effect of the addition of defatted soy flour on the consumer properties of wheat bread has been investigated. The choice of defatted soy flour obtained from high-protein meal as an enriching additive is due to the higher content of proteins, fiber and minerals in comparison with wheat flour. The formulation of wheat bread from wholemeal flour is taken as a basis. Crushed lemon zest, ground black pepper and cumin were added to the recipe to improve the taste and smell of the product. In the experimental samples, in contrast to the control 20 and 30 of defatted soy flour instead of wheat flour was added. Organoleptic and physico-chemical parameters, nutritional value and amino acid composition of proteins were determined in the finished bread samples. It was found that samples of bread with the addition of defatted soy flour have a rich sweet smell and taste with a touch of additives lemon zest, cumin and black pepper. On physico-chemical indicators-the mass fraction of moisture, acidity and porosity samples of bread with the addition of soy flour practically do not differ from the control sample. Samples of bread with the addition of 20 and 30 defatted soy flour have a higher nutritional value than a sample of bread without additives, because they contain more: protein substances in 1,7 and 2 times respectively, fiber by 5080, minerals by 1530 and have a lower starch content: in bread from wheat flour 41,3, in samples with the addition of 20 and 30 defatted soy flour 30,0 and 37,3 respectively. Adding low-fat soy flour to the bread recipe increases the content of essential amino acids in the composition of its protein. Therefore, the use of soybean processing products in baking can be considered as one of the ways to improve the consumer properties of bakery products.
