Research on functional gluten-free sorghum muffins of different varieties

Для больных целиакией стоит проблема при составлении рациона питания, в основном это отказ от изделий, которые содержат в своем составе глютен. Перед хлебопекарными предприятиями стоит задача расширить ассортимент безглютеновых продуктов. При изготовлении продуктов, не содержащих глютен, применяют нетрадиционное сырье: к такому сырью относится сорговая мука. Зерно сорго универсально в использовании, в зависимости от сорта его используют как на пищевые цели, так и на кормовые и промышленные. Цель работы - изучение возможности применения сорговой муки из разных сортов для изготовления функциональных безглютеновых кексов. Анализ оценки качества муки и готовых изделий осуществляли органолептическим и физико-химическим способом. Исследованы показатели качества готовых изделий: пшеничной муки высшего сорта и цельносмолотой, полученной из озимой пшеницы сорта Поволжская Нива, а также цельносмолотой сорговой муки из сортов Рось, Державное, Вера и линии Л-246/17. При определении органолептических и физико-химических показателей выявлено, что цвет муки у контрольных образцов был белый и бежевый. У цельносмолотой сорговой муки в зависимости от сорта от светло-бежевого до коричневого. Влажность муки была в норме и не превышала 15 %. По данным фракционного состава белка, самое низкое содержание глютелинов оказалось у линии Л-246/17 (7,98 %), тогда как у пшеничной муки высшего сорта 31,17 %. Хлебопекарная оценка готовых изделий показала, что все кексы со слегка выпуклой формой корки, пропеченные. Объем и удельный объем кексов из цельносмолотой муки сортов Рось, Державное и линии Л-246/17 больше по сравнению с контрольным образцом из цельносмолотой муки пшеницы сорта Поволжская Нива. Проведен сравнительный анализ сортов зернового сорго для применения их в пищевой промышленности, в качестве безглютенового сырья для производства кондитерских изделий. For patients with celiac disease, there is a problem when compiling a diet, mainly it is the rejection of products that contain gluten in their composition. Bakeries are faced with the task of expanding the range of gluten-free products. In the manufacture of gluten-free products, non-traditional raw materials are used, such raw materials include sorghum flour. Sorghum grain is universal in use, depending on the variety, it is used both for food purposes, and for feed and industrial purposes. The purpose of the work is to study the possibility of using sorghum flour from different varieties for the production of functional gluten-free cupcakes. The analysis of the evaluation of the quality of flour and finished products was carried out by organoleptic and physico-chemical methods. The quality indicators of finished products were studied: wheat flour of the highest grade and whole-ground wheat obtained from winter wheat of the Volga Niva variety, as well as whole - ground sorghum flour from the Ros, Derzhavnoye, Vera varieties and the L-246/17 line. When determining the organoleptic and physico-chemical parameters, it was revealed that the color of the flour in the control samples was white and beige. For whole-ground sorghum flour, depending on the variety, from light beige to brown. The moisture content of the flour was normal and did not exceed 15 %. According to the fractional composition of the protein, the lowest content of glutelins was found in the L-246/17 line 7.98 %, while wheat flour of the highest grade - 31.17 %. The bakery evaluation of the finished products showed that all the cupcakes with a slightly convex crust shape are baked. The volume and specific volume of cupcakes made of whole-ground flour of the Ros, Derzhavnoye varieties and the L-246/17 line is higher compared to the control sample made of whole-ground wheat flour of the Volga Niva variety. A comparative analysis of varieties of grain sorghum for their use in the food industry, as gluten-free raw materials for the production of confectionery products is carried out

Development of flour confectionery products with reduced sugar content

The search for equivalent flavoring sugar substitutes of a non-sugar nature is an urgent direction in the development of the technology of flour confectionery products. In the course of research, a gingerbread recipe has been developed with a partial replacement of the prescription sugar with a 15 % solution of sucralose in glycerin, which most closely correspond to the organoleptic characteristics (taste, smell, texture) of traditional flour confectionery products. The results of the organoleptic evaluation of coded prototypes of gingerbread with the involvement of experts have shown that a decrease in sugar concentration by 25 % does not lead to a statistically significant change in organoleptic parameters in comparison with control samples. Substitution of more than 30 % sugar leads to an increase in the plasticity of the dough complicating the operation of the dosing mechanisms; at the same time, the taste of the products changes (these changes are noted during the tasting assessment); their consistency becomes denser. In the process of research, the stability of the quantitative and qualitative properties of gingerbread during storage has been proved. Experimental samples of gingerbread with 25 % reduced sugar content retain all the indicators established by GOST for their storage for 90 days without statistically significant changes. The decomposition of sucralose in the manufacture of the dough is 0.1 %, in the baking process - 2.6 %, during storage for 120 days - 6.7 % (of the loaded product). The developed recipe allows enterprises to expand the range of confectionery products with reduced sugar content.

The present pandemic situation has increased the demand for plant-based functional foods that enhancing the immunity of all aged groups against COVID-19. This factor has led to innovation in confectionery market because healthy and good quality confectionery products are lacking. In this study, an attempt has been made to develop functional candy from various combinations of banana, ginger, skim milk powder, and honey at 2-10% and evaluated its sensory, nutraceutical, functional properties and microbial stability for 60 days. Among various combinations of banana and ginger pulp, candy prepared from 96:6 w/w (banana: ginger) ratio was found better than other combinations in respect to organoleptic and nutritional quality. Ginger and skim milk powder addition increased the contents of protein (4.54%), ash (2.82%), phenolic (8.59 mgGAE/g), flavonoid (2.43 mQ/g), and antioxidant activity (36.15% DPPH activity) of functional candy. Microbial studies of functional candy revealed it could be stored up to 60 days without microbial contamination and acceptable by the consumer. The cost of functional candy was Rs.1.53 per candy, which was less than market candy. This study showed that candy manufactured from banana, ginger, skim milk powder, and honey was nutritionally and economical improved with acceptable sensory properties. Developed functional candy increases the market's revenue and enables confectionary market to develop a new candy type.

Comparative assessment of the effect of the degree of grinding of vegetables (carrots) on the yield of juices and puree

Some vegetables and fruits are indispensable for the production of a wide range of food, juice and confectionery products, because of their chemical composition and biochemical properties. One of the factors hindering their widespread use in the food industry is the insufficient study of their functional and probiotic properties in the mentioned technological areas. The mechanical properties (approximated dependence, standard deviation, and limit stresses) of the carrot varieties Nantes-5 NABA and Chantenay-2461 intended for juice production have been studied. The enzymatic hydrolysis parameters have been determined based on the parameters of the optimal effect of enzyme preparations. As a result of experimental studies, by determining the extreme loads of squeezing and crushing carrots, the power consumption for grinding carrots was determined. The structure of the carrot pulp was revealed. The highest juice out yield put was observed in the Nantes-5 NABA variety. To increase the juice yield from the pulp, maceration was applied and parameters of enzymatic hydrolysis were determined. Complex two-stage mechanical grinding allowed the production of juice with high organoleptic properties. Antioxidant activity was determined before and after the maceration of carrots. The mode and parameters of the juice production technology were corrected during the research. Ready-made pulpy juice samples were tasted and evaluated. The safety of carrot puree during storage has been verified by analytical research data.

Prospects and Constraints of Sustainable Marketing Mix Development for Poland’s High-Energy Consumer Goods

The research examined awareness, prospects and constraints of sustainable marketing mix development (SMD) from the perspective of Poland’s high-energy consumer goods (HECG), i.e., confectionery products, as an example of the Polish food industry. A questionnaire survey was designed for this purpose. The purpose of the survey questions was to evaluate selected areas of SMD; thus, a reference value ratio was proposed. An original approach to pairwise comparisons technique was applied to rank the value of each survey to provide an intensity measure for each examined area, i.e., a non-heuristic approach with verifiable accuracy and reliability. It was found that a high level of awareness among respondents exists in relation to SMD. Considering all aspects of constraints intensity for SMD, it could be concluded that SMD for Poland’s HECG is at a quite high level. However, considering all aspects of prospects intensity for SMD, this evaluation supported the conclusion that its level for Poland’s HECG is moderate only. It was also found that prices of sustainable products constitute the highest ranked determinant of SMD. Considering these research findings regarding awareness, limitations and perspectives for the development of a sustainable marketing mix in the enterprises operating in Poland’s HECG sector, it can be concluded that there are many more problems and difficulties in implementing sustainable marketing mix programs than there are prospects for the development of this concept.

Influence of gaz modified medium on the safety of flour confectionery products

С целью увеличения срока годности мучных кондитерских изделий проведены исследования влияния газовой модифицированной среды на их органолептические свойства. Изделия были упакованы в лотки из полипропилена и среднебарьерную многослойную пленку на основе полиэтилентерефталата под запайку лотков. Газовая модифицированная среда была представлена смесью углекислого газа и азота в соотношениях 20:80; 30:70; 50:50. Хранение образцов осуществлялось в течение 60 дней. Установлено, что замена воздушной среды на смесь углекислого газа и азота положительно влияла на их сохранность. Показано, что основным критерием сохранности изделий являются органолептические показатели, изменение которых происходят значительно раньше появления признаков микробиологической порчи. Использование газовой модифицированной среды при упаковывании кондитерских изделий позволило увеличить срок годности изделий в 3-6 раз. Наилучшие результаты были получены при использовании газов в соотношении 50:50. Таким образом, использование газовой модифицированной среды может рассматриваться в качестве альтернативы применению пищевых добавок для продления срока годности упакованных мучных кондитерских изделий. In order to increase the shelf life of flour confectionery products, studies have been conducted on the effect of a modified gas medium on their organoleptic properties. The products were packed in trays made of polypropylene and a medium-barrier multilayer film based on polyethylene terephthalate for sealing the trays. The gas modified medium was represented by a mixture of carbon dioxide and nitrogen in the ratios 20:80; 30:70; 50:50. The samples were stored for 60 days. It was found that the replacement of the air environment with a mixture of carbon dioxide and nitrogen positively affected their safety. It is shown that the main criterion for the safety of products are organoleptic properties, the change of which occurs much earlier than the appearance of signs of microbiological spoilage. The use of a modified gas medium in the packaging of confectionery products allowed to increase the shelf-life of products by 3-6 times. The best results were obtained when using gases in a 50:50 ratio. Thus, the application of a modified gas medium can be considered as an alternative to the use of food additives to extend the shelf-life of packaged flour confectionery products.

PREDICTION OF THE SAFETY OF GLAZED CONFECTIONERY PRODUCTS BY THE CONTENT OF LIPOLYTIC MICROORGANISMS

Гидролиз жиров лауринового типа, вызываемый липолитическими ферментами, может придавать глазированным кондитерским изделиям при хранении неприятный «мыльный» привкус, связанный с накоплением свободной лауриновой кислоты. Активность липазы в кондитерских изделиях может существенно изменяться в процессе хранения при микробиологической контаминации, поскольку микроорганизмы – бактерии, плесневые грибы и дрожжи являются активными продуцентами липаз. Проведен мониторинг качества глазурей, изготовленных на основе жиров лауринового типа, различных кондитерских изделий (кондитерских плиток; образцов глазури различных наименований, полученных от производителя, глазури, отделенной от мучных кондитерских изделий и корпусов конфет типа пралине, помадные, сбивные (всего 45 образцов)), в результате которого установлено, что содержание КМАФАнМ во всех образцах глазури составило не более 105 КОЕ/г продукта, дрожжей – менее 50 КОЕ/г, плесеней – 50–100 КОЕ/г. Для исследования влияния микробиологической обсемененности на изменение кислотности кондитерского изделия в процессе хранения были изготовлены модельные образцы глазури с высоким содержанием лауриновой кислоты и долей общего сухого остатка какао 15, 25 и 28%, инокулированные тест-культурами Subtilis Bacillus КВ2-1 и Aerophilus Bacillus 6-1 в количестве 10, 102, 103 и 104 КОЕ/г. На основе математической обработки экспериментальных данных построены графики зависимости кислотности от доли общего сухого остатка какао и обсемененности модельных образцов при хранении в течение 12 мес. Выявлена математическая зависимость, представленная в виде квадратичной функции, позволяющая прогнозировать сохранность глазированных кондитерских изделий. Экстремум функции показывает период хранения глазури, характеризующийся наибольшей скоростью образования свободных жирных кислот. Установлено, что при увеличении микробиологической обсемененности, а также при снижении массовой доли общего сухого остатка какао в какаосодержащем полуфабрикате период хранения, характеризующийся наибольшей скоростью образования свободных жирных кислот, сокращается. На основе полученных закономерностей возможно прогнозирование изменений органолептических показателей глазированных кондитерских изделий, а также кондитерских плиток и фигурных изделий, содержащих жиры лауринового типа, в процессе хранения. The hydrolysis of lauric-type fats caused by lipolytic enzymes can give glazed confectionery products an unpleasant «soapy» taste associated with the accumulation of free lauric acid during their storage. The activity of lipase in confectionery products can significantly change during storage during microbiological contamination, since microorganisms – bacteria, mold fungi and yeast are active lipase producers. Monitoring of the quality of glazes made on the basis of laurine-type fats, various confectionery products (confectionery tiles; glaze samples of various names received from the manufacturer, glaze separated from flour confectionery products and sweets with praline, fondant, whipped cases (45 samples in total)) conducted. According to its results, it was found that the content of CMAFAnM in all glaze samples was no more than 105 CFU/g of the product, yeast – less than 50 CFU/g, molds – 50–100 CFU/g. To study the effect of microbiological contamination on the change in the acidity of the confectionery product during storage, model glaze samples with a high content of lauric acid and a share of the total cocoa solids of 15, 25 and 28%, innoculated with test cultures of Subtilis Bacillus KV2-1 and Aerophilus Bacillus 6-1 in the amount of 10, 102, 103 and 104 CFU/g, were made. On the basis of mathematical processing of experimental data, graphs of the dependence of acidity on the proportion of the total cocoa solids and the contamination of model samples during storage for 12 months were constructed. A mathematical dependence, presented in the form of a quadratic function, which allows predicting the safety of glazed confectionery products, has been identified. The extremum of the function shows the storage period of the glaze, characterized by the highest rate of formation of free fatty acids. It was found that with an increase in microbiological contamination, as well as with a decrease in the mass fraction of the total cocoa solids in the cocoa-containing semi-finished product, the storage period characterized by the highest rate of formation of free fatty acids is reduced. On the basis of the obtained regularities, the prediction of changes in the organoleptic parameters of glazed confectionery products, as well as confectionery tiles and figured products containing lauric-type fats, during storage can be carried out.
