Разработаны рецептуры хлебобулочных изделий на основе сухой подсырной деминерализованной сыворотки «Вимм-билль-данн» с добавлением тонкодисперсного порошка из яичной скорлупы механохимической обработки и растительных порошков из свеклы, клюквы и моркови после инфракрасной обработки. С помощью математического моделирования путем решения задач линейного программирования подобраны оптимальные соотношения ингредиентов рецептур, представленные в виде информационной матрицы для проектирования. Усовершенствована технология приготовления новых хлебобулочных изделий: просеянную сыворотку разводят водой в соотношении 1 : 10, добавляют измельченные овсяные хлопья и замачивают на 15 мин; в полученную смесь вводят ингредиенты: подготовленные дрожжи активированные, порошок ИК-сушки из растительных ингредиентов и порошок из яичной скорлупы, размягченное сливочное масло, просеянную муку с аскорбиновой кислотой; производят замешивание теста в течение 7–8 мин при увеличенной скорости до однородной консистенции; тесто оставляют для брожения на 35 мин, разделывают на шарики массой 50 г и ставят на расстойку на 20 мин, выпекают при температуре 180–200°С в течение 20 мин. Установлено, что ускоренная механическая обработка интенсифицирует процессы приготовления теста, сокращая их продолжительность, мин: брожения с 75 до 35, расстойки с 55 до 20, выпечки от 5 до 2 по сравнению с контрольным образцом. Потребление разработанных хлебобулочных изделий удовлетворяет от 10 до 15% суточной потребности организма в β-каротине, кальции и белке. Разработанные хлебобулочные изделия соответствуют требованиям ТР ТС 021/2011 и рекомендованы в качестве функциональных продуктов детского, диетического и геронтологического питания. Bakery products on the basis of the dry demineralized whey powder Wimm-Bill-Dann with addition of fine powder of an egg shell of mechanochemical processing and vegetable powders of infrared processing from beet, a cranberry and carrots are developed. With the help of mathematical modeling by solving problems of linear programming the optimal ratio of the ingredients of the formulations presented in the form of an information matrix for the design are selected. The technology of preparation of new bakery products is improved: the sifted serum is diluted with water in a ratio of 1 : 10, the crushed oat flakes are added and soaked for 15 min; the ingredients are introduced into the resulting mixture: prepared activated yeast, IR drying powder from plant ingredients and eggshell powder, softened butter, sifted flour with ascorbic acid; kneading the dough for 7–8 min at an increased speed to a homogeneous consistency; the dough is left to ferment for 35 min, cut into balls weighing 50 g and put on proofing for 20 min and bake at 180–200°C for 20 min. It was found that accelerated machining intensifies the dough preparation processes, reducing their duration, min: fermentation from 75 to 35, proofing from 55 to 20, baking from 5 to 2 compared to the control sample. The consumption of the developed bakery products meets from 10 to 15% of the daily needs of the body in β-carotene, calcium and protein. The developed bakery products conform to requirements of TR CU 021/2011 and are recommended as functional products of baby, dietary and gerontological food.

Abstract. Introduction. Domestic food production based on the regional market characteristics can expand the range of functional foods. The research objective was to develop a new technology for desserts based on soy and pumpkin. Study objects and methods. The research featured soybeans of the “Yurna” variety and pumpkin of the “Nadezhda” variety. Soaked soybeans were mixed with mashed pumpkin and drinking water. The mass was heated and kept at 100°C for 30 min with simultaneous grinding and extraction of soluble dry matter. The soy and pumpkin liquid fraction was separated by filtration. A 2.5% aqueous solution of ascorbic acid was added to the liquid fraction at 75–80°C to coagulate protein and other substances. The soy and pumpkin coagulate had a moisture content of 75.0 ± 1%. It was mixed with sea buckthorn syrup and homogenized. The finished product was called “Nadezhda+”. The “Nezhnyi” dessert consisted of gelling solution mixed with soy and pumpkin coagulate and sea buckthorn syrup, after which the mass was homogenized. Results and discussion. The expert assessment helped to identify the most significant indicators of the sensory evaluation of the desserts, namely taste and consistency. The sensory evaluation also made it possible to define the optimal homogenization time for the mix: 60 s for “Nadezhda+” and 90 s for “Nezhnyi”. The developed desserts contained protein (5.75 and 4.70 g/100 g), phosphatides (334 and 102 mg/100 g), β-carotene (2.86 and 1.62 mg/100 g), vitamin E (28.60 and 16.00 mg/100 g) and vitamin C (35.10 and 10.60 mg/100 g), respectively. Conclusion. The content of β-carotene and vitamin E exceeded 15 % of the daily intake in one portion (100 g) of the desserts, as well as vitamin C in “Nadezhda+”. According with State Standard R 52349-2005, the new desserts could be referred to functional foods.

Antioxidant capacity, total phenolic content, colour, sugar, volatiles, ascorbic acid and carotenoid (β-carotene and lycopene) contents of differently coloured and shaped tomato cultivars (cvs) grown in the Eastern Mediterranean region, Turkey were determined, along with a sensory evaluation. Tomato cultivars of two different types (cherry and beefsteak) and four different colours (red, yellow, orange and brown) were analysed. All plants were simultaneously grown in the same field and subjected to identical horticultural practices to minimise the effects of environmental conditions and to maximise those related to genotype. The red cherry cultivar had the highest lycopene content, while the orange beefsteak cultivar had the highest β-carotene content. The highest antioxidant capacity, total phenolic content and hardness scores were found in cherry-type tomatoes, except the yellow one. The red cherry cultivar had the highest sugar content. Red and brown cherry cultivars were also significant in terms of their high carotenoid and sugar contents, along with a high antioxidant activity. The brown cherry cultivar had the highest total phenol content. The highest quantities of 2-hexenal, 3-hexen-1-ol, and 6-methyl-5-hepten-2-one were detected in red cultivars. The brown cherry cultivar had the highest sweetness, typical aroma and hardness scores, while the yellow beefsteak cultivars the lowest sweetness typical aroma scores. In terms of sensory parameters, red and brown cultivars scored higher than yellow and orange ones.   ********* In press - Online First.

This study covers the evolution of color parameters (L*, a*, b*) of passion fruit juice from 2 different seasons (winter and summer) and its relation with carotenoid content and also the sensory evaluation of juices. Three different harvests were made during the two seasons, every 15-20 days. Soluble solids/acidity ratio was used as a maturity index. Winter maturity index was 3.5 and summer index was 6.6: The carotenoids content for winter fruit was higher than that for summer fruit (2.6 and 1.7 mg β-carotene/100ml respectively). Color differences between harvest seasons were observed; a* value for winter juices was higher than for summer juices (7.4 and 4.3 respectively). Furthermore, an increment of a* value was observed in the winter harvest rising from 5.0 to 10.3. A color difference was also detected through the sensory evaluation; the judges ranked the third harvest from winter with the highest degree. This sample had the highest carotenoid content (3.2 mg β-carotene/100 ml).

Yam (Dioscorea spp.) is a tuberous plant of high energy and nutritional value, with great importance for the industry and as a food because of its composition. With the purpose of developing bakery products and determining its acceptability, cake, biscuit, pasta, pancake, bread, and pizza were prepared with 0 to 20% of starch in substitution for wheat flour. Yam starch was obtained when arriving at the industry in Caapiranga-AM, the flagship yam processing town in the region. Sensory evaluation was carried out by a target audience of 50 individuals, using a hedonic scale. For the statistical analysis, the Tukey’s test was used, and it was found that in the overall analysis, the best treatments were the control (no yam starch) and the one with 5% of yam starch. The production of these byproducts is viable, adding value to yam and delivering a product with better quality to consumers.

Quality and nutritional data were obtained for potatoes, carrots, and beets initially and after the raw product was stored for 6 months. Yields of peeled vegetables during 6 months of storage stayed constant for beets but decreased for potatoes and carrots. Proximate analyses for all vegetables remained constant over the storage period with the exception of carbohydrates which decreased slightly. Vitamin C content decreased in all crops while β-carotene in carrots and riboflavin content in beets remained the same over the test period. The nutrient values of products canned immediately or canned after the raw product was stored for 6 months were considered similar. Sensory evaluation results indicate that storage of beets before canning caused changes in flavor and texture characteristics. Storage of carrots before canning had no measurable effect on sensory quality. Sensory evaluation results and Hunter color reflectance values indicated a color change toward yellow, and preference for a white-fleshed potato.

Natural sweeteners, such as agave syrup, might be a healthy alternative to sucrose used in sweet bakery products linked to obesity. We evaluated the effect of sucrose replacement by agave syrup on rheological and microstructural properties of muffin batter and on physical and sensorial properties of the baked product. Muffins were formulated by replacing 25%, 50%, 75%, and 100% of sucrose by agave syrup (AS) and partially hydrolyzed agave syrup (PHAS), and by adding xanthan gum and doubled quantities of leavening agents. Rheological and microstructural properties of batter during baking were analyzed over the range of 25–100 °C. In the muffins, the structure, texture, color, and sensory acceptance were studied. The combination of agave syrup with xanthan gum and doubled quantities of leavening agents affected (p < 0.05) rheological and microstructural properties of the batters and textural properties of the low-sucrose muffins compared to the controls. The increase in agave syrup levels resulted in a darker crumb and crust. Sensory evaluation showed that AS-75 and PHAS-75 were the best alternatives to the control samples. Our results suggest a plausible substitution of up to 75% of sucrose by agave syrup in preparation of muffins, with physical and sensorial characteristics similar to those of their sucrose-containing counterparts.

Gluten, a visco elastic protein present in the wheat causes damage to the small intestine and as a result the microvilli of the small intestine gets atrophed. This situation leads to abdominal discomfort and malaborption of many vital vitamins. This condition is called as Gluten Sensitivity or Celiac Disease, following a gluten free diet is most suitable treatment. Gluten free cereals can be used in diet, but they can’t replace wheat in bakery products. The present study was conducted to develop gluten free cookies with quinoa, a nutrient dense pseudocereal. Three different types of cookies using two different types of quinoa flour were prepared. Sensory evaluation and nutritive value of the cookies revealed that Quinoa cookies have excellent sensory attributes and also they are high in nutritive value. Among all cookies made corn flake cookies (C1) cookies are much more appreciated than cinnamon cookies (C2) and salt cookies (C3).
