PurposeThe effects of incorporation of Locusta migratoria (LM) powder at different levels (0, 1, 2, 3, 4 and 5%) on nutritional, qualitative and sensory properties of baked breads were investigated.Design/methodology/approachChemical composition, mineral elements and functional properties of wheat flour, LM powder and their binary mixture systems were determined. The breads were assayed for proximate composition, minerals, amino acids profile, physical characteristics and sensorial properties.FindingsLM powder have relatively high levels of protein (51.97% db), fat (23.15% db) and fibers (13.76% db). LM powder presented significantly (p ≤ 0.05) greater water absorption capacity (WAC), oil absorption capacity(OAC), emulsion activity (EA) and foam capacity (FC) as compared to wheat flour. Blending wheat flour with various levels of LM powder significantly (p ≤ 0.05) improved the functional properties of binary mixture systems. Protein, fat, fiber and ash contents of bread samples significantly increased with the addition of LM powder. No significant differences (p ≤ 0.05) were recorded in specific volume between control breads and those breads containing LM powder up to 2%. Breads fortified with LM powder contained higher values of essential amino acids than the limits of FAO/WHO pattern, with exception of lysine. Sensory evaluation results showed that bread samples with the addition of LM powder at levels 1–4% had high overall acceptability.Research limitations/implicationsLimitations of our study are the lack of approved and professional programs about management, collection, harvesting, processing, marketing and consumption of edible insects; therefore, these results should be generalized implications for industry. This present study, therefore, provides useful data to support public health nutrition aimed at improving the nutritional health of populations through the promotion of bakery products enriched with LM powder.Practical implicationsThe main findings of this study indicated that the addition of 1–4% of LM powder into wheat flour enhanced sensory and nutritional properties of produced breads.Originality/valueIt is concluded that the addition of LM powder improves the nutritional and sensorial properties of the produced bread when the wheat flour is substituted with 1–4% of LM powder.

A Value

The functional properties of protein isolate and major protein fractions prepared from Changbai Mountain pine nuts were investigated. Albumin, globulin, glutelin, and protein isolates were obtained after the Osborne method and alkaline dissolution and acid precipitation, and protein contents of the fractions are 48.02%, 81.93%, 83.02%, and 89.69%, respectively. For the sulfhydryl contents, albumin is the highest, and glutelin is the lowest. In a disulphide bond, the protein isolate content is the highest with a value of 28.74 μmol/g, and the glutelin content is the lowest with the value of 13.46 μmol/g. For the four kinds of proteins, the essential amino acids in percentage of total amino acids are 31.13%, 34.22%, 30.30%, and 34.54%, respectively. The pH dependent protein solubility profile reveals that the minimum solubility is at pH 5.0, which corresponds to the isoelectric point. Protein isolate has the minimum water absorption capacity with a value of 0.59 ml/g. On the other hand, albumin has the minimum oil absorption capacity with a value of 2.11 ml/g. The emulsifying activity and stability and the foaming activity and stability increased with increasing concentration of four kinds of proteins. SDS-PAGE results showed that these four kinds of proteins have different molecules.

Functional Features

Dietary fibre has a beneficial effect on human health that is manifested, among other things, in a reduced risk of obesity, diabetes or neoplasms. Its numerous functional properties render it a desirable food additive. The objective of the research study was to assess the nutritional and functional properties of a novel rapeseed protein-fibre concentrate (RPFC) developed by a NapiFeryn BioTech company. The chemical composition, including the amino acid composition, and the functional properties of RPFC were compared with those of the soy fibre (SF) and pea fibre (PF) available on the market; the purpose of the comparison was to evaluate the potential of RPFC as a novel ingredient for use in food applications. The research study showed that RPFC contained significantly more protein than SF and PF. At the same time it was found that the level of total dietary fibre in RPFC was similar to the level of this ingredient in SF. What's more, RPFC was characterized by the highest contents of ash and phytic acid. Based on the analysis results of amino acids it was proved that the level of lysine was the highest in RPFC. The RPFC was characterized by a higher content of essential amino acids than PF and a lower content thereof than SF. RPFC was distinguished by good functional features, such as emulsifying activity, emulsion stability, and water and oil absorption capacity. It was showed that RPFC had suitable features to be used as a functional food ingredient in food products.

As part of this functional food covenant, the world is searching for new healthy food products with ample quantities of bioactive components such as fibre, mineral elements, essential amino acids, and phenols. Since CHIA seeds powder has both nutritious and pharmaceutical  properties, integrating it into pan bread  may be  beneficial  to  human  health. The sensorial parameters of pan bread enriched with CSP, amino acids composition, and proximate  compositions  of the pan bread were investigated in this study by partially replacing  wheat  flour (WF) with  CHIA  seeds  powder  (CSP) at  levels  of  3  percent, 6  percent, 9 percent, and 12 percent. The addition of CSP to pan bread  improved  the mineral content of the bread. With  only  a minor depreciation in bread  quality, CSP could  partially replace  WF  72 percent extraction in pan bread, increasing its nutritional value in terms of  fibre, essential amino acids, and minerals. Sensorial evaluation revealed that pan bread supplemented with up to 12% CSP was acceptable to the panelists, with notable differences in crumb texture, appearance, crust color, crumb grain, taste, odor, and overall acceptability as compared to pan  bread   control. When compared  to  pan bread  without  CSP, the CSP  mixture  increased the mineral  content, essential  amino  acid  content, and nutritional   properties.

Composite Bread

PurposeSoaked–dehulled moth bean seed (SDMBS) powder was incorporated into wheat flour and the paper aims to investigate its effects on the nutritional and quality properties of composite bread.Design/methodology/approachDifferent ratios of SDMBS powder (0%–12.5%) were mixed into wheat flour to prepare composite bread. Proximate composition, mineral content and functional properties of SDMBS powder and wheat flour were studied. The composite bread samples were assayed for proximate composition, mineral nutrients, amino acid composition, physical characteristics as well as sensorial properties.FindingsProtein and ash contents of SDMBS powder were found to be 2.15 and 5.69 fold higher than wheat flour. Water absorption capacity (WAC), oil absorption capacity (OAC), (FC) and emulsion activity (EA) values of SDMBS powder were also 1.63, 1.78, 4.43 and 1.58 times higher than wheat flour, respectively. The inclusion of different levels of SDMBS powder into wheat flour significantly (p = 0.05) increased the functional properties of composite flours. Bread samples fortified with SDMBS powder exhibited higher values of essential amino acids than the recommendations of World Health Organization/Food and Agriculture Organization/United Nations University (2007). The bread samples containing 10% and 12.5% of SDMBS powder provided 39.23% and 41.15% of the recommended lysine level, respectively. The addition of a higher proportion of SDMBS powder into wheat flour gradually increased the protein and ash contents of the bread samples. Control sample without SDMBS powder (0%) and samples fortified containing 2.5% and 5% of SDMBS powder received the highest scores of overall acceptance, whereas the bread sample with the highest SDMBS powder (12.5%) content received the lowest scores.Research limitations/implicationsThe main findings of the current investigation indicated that the addition of 2.5–5% of SDMBS powder into wheat flour enhanced the nutritional and quality characteristics of wheat bread.Originality/valueSDMBS powder could be incorporated into refined wheat bread to achieve functional bread with significantly higher protein content.

The aim of the work was to optimize the process of obtaining multicomponent protein compositions with high biological value and higher functional properties than the original vegetable protein products. Was realized studies to obtain biocomposites on the base of pea protein-oat protein and pea protein-rice protein. Developed composites were enriched with all limited amino acids. For each of the essential amino acids, the amino acid score was 100% and higher. Protein products used in these compositions are not in major allergen list, which allows to use these compositions in allergen-free products and specialized nutrition. To determine biosynthesis parameters for compositions from pea protein and various protein concentrates with the use of transglutaminase enzyme, was studied effect of concentration and exposition time on the amount of amino nitrogen released during the reaction. Decreasing of amino nitrogen in the medium indicated the occurrence of a protein synthesis reaction with the formation of new covalent bonds. Were determined optimal parameters of reaction: the hydromodule, the exposure time, the concentration of EP of the preparation, were obtained mathematical models. Studies on the functional properties of composites, the physicochemical properties of the proteins that make up their composition, and structural features will make it possible to determine the uses in the manufacture of food products based on their ability to bind fat, water, form foam, gels, and etc.

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.
