Impact of Raw, Roasted and Dehulled Chickpea Flours on Technological and Nutritional Characteristics of Gluten-Free Bread

The main objective of this study was to develop a healthy rice-based gluten-free bread by using raw, roasted, or dehulled chickpea flours. All breads containing chickpea flours showed a darker crust and were characterized by an alveolar (porosity 41.5–51.4%) and soft crumb (hardness 5.5-14.1 N). Roasted chickpea flour bread exhibited the highest specific volume, the softest crumb, and the slowest staling rate. Enriching rice-based breads with the chickpea flours resulted in increased protein (from 9.72 to 12.03–13.21 g/100 g dm), ash (from 2.01 to 2.45–2.78 g/100 g dm), fat (from 1.61 to 4.58–5.86 g/100 g), and total phenolic contents (from 49.36 up to 80.52 mg GAE/100 g dm), and in reduced (~10–14% and 13.7–17%, respectively) available starch levels and rapidly digestible starch compared to rice bread. Breads with roasted chickpea flour also showed the highest in vitro protein digestibility. The results of this study indicated that the enrichment of rice-based gluten-free breads with chickpea flours improved the technological and nutritional quality of the breads differently according to the processed chickpea flour used, also allowing recovery of a waste product.

Use of chickpea flour in food production

Currently, the production of special varieties of bread and bakery products using non-traditional plant raw materials is relevant. The article presents the results of studies on the introduction of chickpea flour into the recipe of wheat bread. Chickpea is a crop that is adapted to vegetation in unfavorable soil and climatic conditions of the Volgograd region. Chickpeas are high in protein (up to 32%) and fat (8%), while the amount of carbohydrates is insignificant (up to 5%). In the laboratory, test baking of bread was carried out using the following options: wheat bread (control) and wheat-chickpea bread. Chickpea flour was added to wheat flour in the amount of 5, 10, 15 and 20%. Before baking, a study of wheat flour and mixtures of wheat flour with chickpea was carried out for the content and quality of crude gluten. The addition of chickpea flour has been found to reduce the amount of wet gluten, but not to decrease its quality group. After test baking, the volume of the bread was measured and the organoleptic characteristics were determined. It was found that the addition of chickpea flour leads to a decrease in the volume of the finished product. The bread with the addition of chickpea flour differed from the control variant in the color of the crust and crumb. The pulp was denser and finer. The taste and smell of chickpea were felt only in the variants with the addition of 15 and 20% chickpea flour. The addition of chickpea flour contributed to the enrichment of wheat bread with essential amino acids. With the consumption of 300 g of bread containing 80% wheat and 20% chickpea flour, the daily requirement of the human body for essential amino acids would be satisfied by 48.8%.

Gluten-free products from chickpea flour

The paper discusses the possibility of the expansion of the range of flour culinary products for a gluten-free diet using chickpea flour. The analysis of the chemical composition of wheat and chickpea flour, as well as the glycemic index of all components of the recipe of the developed flour culinary product is presented. The possibility of partial and complete replacement of wheat flour with chickpea flour with the addition of caraway, lemon peel and potato starch is studied. It is found that the inclusion of lemon peel in the composition of chickpea flour pancakes improves not only the organoleptic characteristics of products, but also reduces its total energy content, while expanding the range of products included in a gluten-free diet.

Determining the optimal parameters of ultra-high-frequency treatment of chickpeas for the production of gluten-free flour

This paper describes the materials and results of studying the properties of such a leguminous crop as the chickpea variety Miras 07 of Kazakhstan selection in order to obtain gluten-free flour and further process it to produce confectionery products. The research involved the ultra-high-frequency (UHF) treatment of chickpea grain to improve quality indicators and reduce anti-alimentary factors. A change in the protein fraction of chickpeas was determined under exposure to ultra-high-frequency processing. The study has proven the effectiveness of ultra-high-frequency treatment of chickpea for 180 seconds. Based on chemical analysis, it was found that the exposure to ultra-high-frequency treatment fully preserved the vitamin and mineral complex, compared with untreated chickpeas. When chickpea grain is heated for 180 seconds, up to 20 % of the starch contained in the grain passes into dextrin, which is easily absorbed by humans while the toxic substances are destroyed. The change in the protein fraction of chickpeas during ultra-high-frequency processing was determined. With ultra-high-frequency treatment of chickpea flour at 180 seconds of exposure, the protein fraction content remains unchanged at 79.8 %. The result based on the IR spectrum data indicates that ultra-high-frequency processing did not affect the protein-amino acid composition of the examined Miras 07 chickpea variety. The current study has confirmed the effectiveness of ultra-high-frequency chickpea treatment, which leads to the intensification of biochemical processes in the processed product due to the resonant absorption of energy by protein molecules and polysaccharides. Under the influence of ultra-high-frequency treatment, there is a decrease in the microbiological contamination of raw materials while the organoleptic indicators improve. According to the microbiological indicators of chickpea flour, the content of microorganisms was 1×103 CFU/g, which meets the requirements for sanitary and hygienic safety

Potential of Chickpea Flours with Different Microstructures as Multifunctional Ingredient in an Instant Soup Application

Chickpea flours are an interesting multifunctional ingredient for different food products. This study investigated the potential of differently processed chickpea flours as alternative thickening agents in an instant soup recipe, replacing potato starch. Dry instant soup powders were compared on bulk density and powder flowability, whereas prepared liquid instant soups were studied in terms of rheological behaviour (as influenced by microstructure) and volatile composition. The chickpea-flour-containing soup powders possessed similar powder flowability to a reference powder but were easier to mix and will potentially result in reduced blockages during filling. For prepared liquid instant soups, similar viscosities were reached compared to the potato starch reference soup. Nevertheless, the chickpea-flour-containing soups showed higher shear thinning behaviour due to the presence of larger particles and the shear induced breakdown of particle clusters. Flavour compounds from the soup mix interacted with chickpea flour constituents, changing their headspace concentrations. Additionally, chickpea flours introduced new volatile compounds to the soups, such as ketones, aldehydes, alcohols, and sulphur compounds, which can possibly alter the aroma and flavour. It was concluded that chickpea flours showed excellent potential as alternative thickening ingredient in instant soups, improving the protein, mineral and vitamin content, and the powder flowability of the soups, although the flavour of the soups might be affected by the changes in volatile profiles between the soups.

Improving the recipe of a confectionery product based on chickpea flour and cranberries

The results of researches of influence of gluten-free chickpea flour on quality of confectionery are presented. A systematic analysis of scientific and technical information of Ukrainian and foreign scientists and formulated a working hypothesis on the possibility of using alternative ingredients in the production of confectionery. The object and subject of research are selected: technology for the production of cupcakes; chickpeas flour, strawberries cranberries. The chemical composition of chickpea and wheat flour is characterized by the quantitative content of proteins, fats, carbohydrates, minerals, vitamins. It was found that chickpea flour can be an alternative source of protein, it contains in the vast majority necessary for the full development of the human body calcium, phosphorus, magnesium. On the basis of the performed experimental researches the recipe of cakes with use of industrial samples is developed: chickpea flour of TM "Organic-Eco-Product", cranberries dried of TM "Bakalland", chicken eggs of category C1, granulated sugar of TM "Svoi Liniya", sweet butter 72,6 % TM "Belotserkivske" and baking powder TM "Dr.Oetker". Effective technological parameters and rational ratios of prescription ingredients for creating a cake have been established. Drawings of experimental samples of cupcakes are presented and characterized. The method of scoring has shown that the use of chickpea flour in the technology of confectionery production affects the organoleptic characteristics of the quality of finished products and structural and mechanical properties of the crumb. Consumer surveys and questionnaires were conducted in the city of Dnipro in ATB and Varus supermarkets to determine the general opinion about food. Ukrainians were interviewed: "Do you pay attention to new products that appear on the market?", "How often do you buy pastries in the store?". It was found that 50% of consumers pay attention to new products and 47% buy pastries every day. It is substantiated that the use of the proposed formulation will allow to obtain a new product based on chickpea flour, which will provide people with celiac disease with quality treatment and prevention products.
