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.

The objective of this study was to evaluate the nutritional, non-nutritional as well as physico-chemical characteristics of biscuits developed from the supplementation of wheat flour with different levels of whey protein concentrate (WPC). The biscuits were prepared by using composite blends of wheat flour (WF) and WPC in different combination such as 100:0 (WF), 95:5 (WWP 5%), 90:10 (WWP 10%) and 85:15 (WWP 15). Proximate analysis of control as well as treated sample showed significant rise in crude protein content, with increase in WPC supplementation. Moreover, Non-nutritional factor such as tannin content and polyphenols was found to be highest in WF sample followed by WWP (5%), WWP (10%) and WWP (15%). In addition to that, in-vitro protein digestibility (IVPD) was found to be highest in WPC and when IVPD was compared with the crude protein, a significant difference was observed. Additionally, with the increase in WPC ratio the concentration of lysine, aspartic acid and glutamic acid was improved. Moreover mineral analysis revealed that, WF had highest amount of iron 0.66 mg/100g followed by WWP (5%), WWP (10%), WWP (15%) and WPC. Moreover, spread ratio of cookies found to be significant with the increase in the levels of WPC. Sensory evaluation of the samples revealed that, WWP (15%) had highest acceptance rating followed by WWP (10%). Based upon our investigation, we found that WPC could be a good source of supplementation for the development of protein enriched biscuits to combat the problem of malnutrition.

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.
