The aim of this study was to examine the sensory properties of dietary cookies produced with addition of different dietary fiber sources (inulin and ligofructose, oat flakes, mixture of oat flakes and wholemeal flour, wholemeal flour and mixture of wholemeal flour and carob flour), and to measure instrumentally color changes of cookies upper and lower surfaces, after storage at temperatures of 18-20°C for 180 days. Addition of inulin and oligfructose was determined to be the fiber source with the highest impact on sensory properties. Storage for 180 days expressed the highest influence on texture properties of dietary cookies regardless of applied dietary fiber source. Color differences calculated from measured color properties (psychometric light, L*, psychometric tone, a*, and psychometric chrome, b*) between products including different fiber sources were noticeable to extremely noticeable among products, with the most expressed difference registered for products containing carob flour
The aim of this work was to compare the nutritional characteristics of wheat bread with the bread produced of wheat flour supplemented with quinoa and buckwheat seeds. Bread making properties of these blends were analyzed in order to investigate their ability to make moulded bread. Quinoa (Chenopodium quinoa Will.) and buckwheat seeds were grown in the vicinity of Belgrade, Serbia. The addition of pseudocereal seeds (at levels of 30% and 40%) and a selected technological process, which included hydrothermal preparation of supplements, resulted with a valuable effect on nutritive value of breads. In comparison with the wheat bread that was used as control sample, the protein increase of 2% and the increase of crude fiber content at around 0.5% in 30% supplemented breads were registered. Furthermore, the incorporation of both seeds mixture at the level of 40%, increased the content of protein for 2.5% and fiber content for 0.4%. In regard to the starch, fat, and ash contents there were no major differences. The investigated breads were nutritionally superior to the wheat bread. Chemical composition of the selected seeds was also investigated. The results showed that the blends containing either 30% or 40% of selected seeds expressed high potential for the production of molded breads, as new baking products with enhanced nutritional composition. The applied technological procedure was modified in such way that for all blended combination of supplements it changed rheological properties of dough. Furthermore, it resulted in a good volume of breads with excellent sensory properties of aroma-odor and taste
Plum kernels of the “Čačanska rodna” variety, by-products from plum brandy production, were collected before and after fermentation and distillation, and used for cold-pressed oil production. Fatty acid and tocopherol contents were determined by capillary GC and HPLC, while the oxidation stability of the resulting cold-pressed oils was tested by the Rancimat method. The results showed that oleic fatty acid was dominant in the oil samples with a content of 56.6 to 61.8%, regardless of the plum kernels’ origin. The fermentation and distillation processes had a pronounced effect on the tocopherol content and oxidative stability of the resulting kernel oils. Tocopherol contents were 61.8 mg·100g-1, 87.4 mg·100g-1, 79.6 mg·100g-1 of oil, while the induction periods were 38.7, 44.4 and 33.6 hours for samples before fermentation, after fermentation and distillation, respectively. Based on the results, it could be concluded that the fermentation process increased the content of tocopherols in kernel oil whereas the high temperature during the distillation process adversely affected the tocopherol content and oxidative stability of the obtained kernel oil.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
