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.

Abstract Marshmallow is sugar-candy with foam-like structure. Many studies have revealed the high nutritional value of bee pollen. Due to the nutritional composition of pollen, and according to nonscientific studies, dried bee pollen has been used as an additive in human diets, which provides a well-being sensation and contributes to functional and harmonious balance of the body. Sensory evaluation and market research are an important part of developing a new product. The research was aimed to clarify the situation in the Latvian market, to summarise Latvian consumer attitude on marshmallow, and to determine the sensory properties and quality of marshmallows with bee pollen. A questionnaire was developed - 900 respondents answered questions about their consumption patterns, opinions on quality indices, and possible types of marshmallow packaging. Marshmallow was enriched with three different pollen concentrations: 1.0; 1.5 and 2.5%. Sensory evaluation was carried out to estimate the optimal concentration of bee pollen that which should be added to marshmallow. Sensory evaluation of experimental marshmallow was characterised by using a 9-point hedonic scale (determination degree of liking). The obtained results showed that consumers liked the marshmallow with 1.5% bee pollen best of all.

Moringa oleifera is local plant rich in nutrients, unfortunately its utilization as a foodstuff is limited. In order to maximize the absorbtion of nutrients inside moringa, it should be made as favor food enjoyed by the people such as jelly candy. This research was conducted to evaluate organoleptic properties and nutritional value (energy and â-caroten) of jelly candy formulated with Moringa leaves powder. Using Comlpetely Randomized Design with 6 times repetition in 4 formulas which are 1 controlled formula and 3 modifi ed formulas (F1, F2, and F3), jelly candy then tested to 32untrained panels. Treatment given in this study was by adding 2%, 4%, and 6% moringa leaves powder into jelly candy formula. Data was analyzed descriptively and statistically using Kruskal Wallis and Mann Whitney test to fi nd out the difference pair. Recommended formula was chosen by counting the highest mean score of the sensory evaluationtest. The result of sensory evaluation showed that Moringa Jelly Candy was generally accepted with category “like”. However, jelly candy with lowest level of Moringa leaves powder (F1) was most acceptable in terms of color, odor, texture, and fl avor. Statistical analysis showed that the scores of color, odor, and texture were not signifi cantly different (p > 0.05) and fl avor was (p < 0.005) which means that by adding moringa leaves powder into jelly candy formula only infl uence the fl avor of jelly candy. Recommended jelly candy formula is F1 with nutritional analysis showed that per 100 g of jelly candy contains 205,8 kcal and 0.178 mcg of B -caroten.Keywords: moringa leaves powder, sensory evaluation, Moringa oleifera, jelly candy

This study was conducted to explore the possibility of substitution of wheat flour with 10%, 20%, 30%, 35% and 40% buckwheat (Fagopyrum esculentum) flour and to formulate bread with improved nutritional value along with acceptable nutritional and sensory attributes, and to compare with locally available breads. The results showed that the ash (0.80-1.21%), protein (10.11-16.23%), fat (4.88-5.85%), fiber (0.07-0.19%), energy (301-322 kcal/100g) and mineral contents were increased with the increasing content of buckwheat flour in the bread preparation. Physical characteristics were decreased with the increasing content of buckwheat flour. On sensory evaluation, bread formulated with 30% buckwheat flour was found acceptable. In comparison with locally available breads, 30% buckwheat flour substituted bread was found significantly higher in ash, protein, fiber and energy content. Based on these results, it can be concluded that bread prepared with 30% substitution of wheat flour with buckwheat flour is nutritionally superior over locally available breads. Bangladesh J. Sci.

Recipes and technologies for the production of bakery products with rice processing products based on the composition of flour composite mixtures to increase their nutritional value have been developed. Samples of rice flour and flour, corn flour and wheat flour of general-purpose type M55-23 of domestic producers were studied. The control sample is a recipe for bread made from general-purpose wheat flour. The prototypes consisted of composite mixtures (CM): I CM – general-purpose wheat flour and rice flour in a ratio of 90 : 10; II CM – general-purpose wheat flour, rice flour, corn flour and grain rice processing products in a ratio of 50 : 20 : 20 : 10. The target improver is apple pectin. The maximum specific volume of samples of tin bread of adding 0,3% pectin in a mixture with table salt with subsequent dissolution of the resulting composition in water, cm3/100 g was defined: control – 289; with I CM – 285; with II CM – 280. The nutritional value of proteins was 8,12; 8,55; 9,12 g/100 g in the samples of bread control, «Luchik», «Maniya», respectively. Vitamin content, mg/100 g: B1 – 0,31; 1,36; 1,46; B2 – 0,26; 1,32; 1,52; PP – 0,47; 3,55; 4,02 inthe control bread samples, «Luchik», «Maniya», respectively. It was found that the introduction of CM based on rice grain processing products into the recipes of wheat bread «Luchik» and «Maniya» increases the protein content by 6 and 12%, fat by 2–2,5 times, respectively, compared to the control. Adding grain rice processing products, rice flour and corn flour to the recipe of bakery products was increased the content of K and P in 100 g of the finished product by 3–3,5 times, Mg and Fe by 4–4,5 and 6–6,5 times, respectively, vitamins B1 and B2 by 4,5–5,5 times, respectively, vitamin PP by 8 times, which was increased the nutritional value of minerals by 2 times, and vitamins by 7 times compared to the control. The energy value of new products increased by an average of 18% compared to the control. It was found that when using 250 g of bread «Luchik» on based the I CM, the degree of satisfaction of the body in protein for men and women of the III activity group aged 30–39 years and children aged 14–18 years was 26,8% of the daily requirement; in minerals – 15,7; 16,7 and 18,9%, respectively. When using 250 gof bread «Maniya» on based II CM, the degree of satisfaction in protein was 25,6; 30,8 and 28,5% of the daily requirement, respectively.

AbstractRheological properties of doughs prepared from wheat flour with buckwheat and quinoa flour addition (2.5 mass %, 5.0 mass %, 7.5 mass %, and 10 mass %) were investigated using a farinograph and compared with those of standard dough (without addition of pseudocereals). The following characteristics were determined: water absorption capacity, water consumption, dough growth time, level of dough softening, dough stability, mechanical resistance, and dough elasticity. Dough stability showed a linear decrease with the increasing content of pseudocereals. Doughs containing quinoa flour were more stable than those with buckwheat flour addition. Dough growth time was reduced with increasing amounts of buckwheat flour but it was not affected in the case of quinoa flour addition. From the comparison of the studied characteristics it can be concluded that an addition of lower amounts of quinoa (up to 5.0 mass %) to wheat flour will not significantly impair rheological properties of the dough but provides for enhanced nutritional value of the prepared bakery products.

Legume flours, due to their phenol and fibre content, are ideal ingredients for improving the nutritional value of bakery products. In this study, artichoke stem powder (ASP) was used to substitute 0%, 2.5%, 5%, 7.5% and 10% of wheat flour for making breads. Proximate composition of wheat flour and ASP were determined. Bread qualities and total phenols content were analyzed and compared with those of wheat bread. Results show that ASP contained 10.37% moisture, 10.28% ash, 11.53% protein, 0.86% fat, 51.29% fibre and 1350 mg EAG/100g d.m. ASP addition considerably modified the bread quality: altered appearance and texture, darker crumb and more intense odour were observed. From the sensory evaluation, tastes of bread with higher content of ASP (7.5 and 10%) were the most acceptable for assessors. Total phenol contents of breads significantly increased with the addition of ASP. Therefore ASP may be considered as valuable ingredients for industrial manufacture of functional foods.

AbstractIn this study, the potential of the substitution of the conventional preservative potassium sorbate by fermented wheat flour as an alternative was analysed. The organic acid content and antibacterial activity of preservatives and the macronutrient characterisation were tested, as was the sensory evaluation of biscuits with added conventional and alternative preservatives. The results show that the fermented wheat flour contains secondary fermentation metabolites (e.g. acetic, lactic and pyruvic acids). Both fermented wheat flour and potassium sorbate have antibacterial effects against Staphylococcus aureus, Bacillus cereus and Bacillus subtilis. The sensory evaluation demonstrated that fermented wheat flour in the recommended concentration range had no impact on sensory quality. Therefore, fermented wheat flour represents a potential substitution for conventional potassium in bakery products.
