One form of common wheat with yellow coloured grain, two forms of emmer wheat, and two forms of barley with hulless grain were used for the preparation of bread with enhanced nutritional quality. The following mill products were prepared from the cereal grains: wholemeal flour, break flour, barley grits, and break bran. The contents of thiamin, niacin, pyridoxine, total polyphenols, and total dietary fiber were studied in these raw materials and bread samples. Further, in the bread samples, the antioxidant activity was assessed and sensory evaluation was performed. As a result, the utilisation of the non-traditional forms of cereals improved nutrient contents of bread while maintaining very good sensory characterising and processing quality.

This study compares the content of basic nutrients (proteins, fats, digestible carbohydrates, dietary fiber and ash), steviol glycosides, selected antioxidants (vitamin C, total polyphenols) and antioxidant activity in dried leaves of Stevia rebaudiana Bertoni cultivated in Poland, Paraguay and Brazil and available in the direct sale. The basic chemical composition was determined by standard AOAC (Association of Official Analytical Chemists) methods. Content of steviol glycosides was determined by the UHPLC-UV chromatographic method. Total polyphenols content was expressed as gallic acid equivalent (GAE) and catechins equivalent (CE). Antioxidant activity was measured as ABTS●+ free radical scavenging activity. Dried leaves of S. rebaudiana grown in Poland had significantly higher contents of dietary fiber, and lower protein and ash content, compared to those derived from Paraguay and Brazil. The former had, however, considerably higher contents of total steviol glycosides, stevioside and rebaudioside D, compared to the remaining two plants. In the Paraguay-derived dried leaves, the content of rebaudioside A, C, E and rubusoside was found to be significantly lower. Dried leaves of S. rebaudiana Bertoni, cultivated in Poland, contained substantially more vitamin C and a similar content of total polyphenols, compared to those from Brazil and Paraguay. The examined material from Brazil and Paraguay plantations showed similar antioxidant activity, while that obtained from Polish cultivation was characterized by a significantly lower value of this parameter.

Beet Pulp

Sugar beet pulp (SBP) is a by-product of the sugar industry in which the dietary fiber content ranges from 73% to 80%. Compared to cereal fibers mainly used in biscuit production, sugar beet fibers are gluten free and have a perfect ratio of 2/3 insoluble fiber. In this work, sugar beet pulp was extruded with corn grits (ratios of corn grits to sugar beet pulp in extrudates were 85:15, 70:30, and 55:45), and the obtained sugar beet pulp extrudates (SBPEs) were used for improving the nutritional quality of cookies. The wheat flour in cookies was replaced with SBPEs in the amount of 5, 10, and 15%. The influence of three factors (the percentage of sugar beet pulp in the SBPEs, the size of the SBPE particles, and the percentage of wheat flour substituted with SBPEs) and their interactions on the nutritional quality of cookies, as well as their physical and sensory characteristics are examined using the Box–Behnken experimental design. The addition of extruded sugar beet pulp (SBPEs) significantly increased the amount of total dietary fiber and mineral matter of cookies. On the whole, the addition of SBPEs increased cookie hardness, but the hardness decreased with an increase in extrudate particle size. Sensory characteristics (except for the taste) were the most influenced by extrudate particle size.

The potential of wheat bran (WB) addition as a prebiotic source were demonstrated using yogurt with probiotics (Lactobacillus acidophilus and Bifidobacterium lactis). Yogurts (with 4% WB) were significantly (P < 0.05) different in total bacterial counts (9.1 log CFU/mL), and total titratable acidity % (TTA, 1.4%) compared to controls during 28 days cold storage (4°C). Additionally, WB-total dietary fiber contents and their bound phenolic profiles were investigated as well as the antioxidant activity of WB-water extractable polysaccharides (WEP) was studied. HPLC analysis of alkaline hydrolyzed DF fractions showed that insoluble DF had higher phenolic acids (84.2%) content than soluble DF (15.8%). Also, crude-WEP showed stronger antioxidant activity compared to purified-WEP with an ORAC of 71.88 and 52.48 µmol TE/g, respectively. Here we demonstrate WB has potentials as a source of prebiotics, which may have the potentials for functional foods and nutraceutical applications.

The aim of this study was to evaluate the quality and health-promoting constituents of several variants of kimchi obtained from Chinese cabbage, kohlrabi, white radish, and cucumbers. The level of dry matter, total soluble solids, ash, total acidity, pH, dietary fiber, and vitamins C, B1, and B2, as well as total polyphenols (TP) and antioxidant activity AA (ABTS, DPPH) in kimchi, were determined. In addition, color parameters were determined ( L ∗ , a ∗ , b ∗ , C ∗ , and h o ). Kimchi with the highest proportion of Chinese cabbage (63%) had the highest levels of dry matter (11.01 g), ash (2.57 g), and vitamins: C, B1, and B2 (51 mg, 52 μg, and 242 μg, respectively), expressed per 100 g of fresh weight. In addition, this product showed the highest total AA of 132.3 μmol Tx/g (ABTS) and 49.7 μmol Tx/g (DPPH) due to its high level of TP (194 mg/100 g). Cucumber-derived kimchi (85%) also had a high content of TP (147 mg/100 g) and high AA of 88.7 μmol Tx/g (ABTS) and 36.3 μmol Tx/g (DPPH). Additionally, stuffed kimchi from kohlrabi (88%) had the highest amounts of total dietary fiber, 3.65 g/100 g fresh weight. In all products, red ( a ∗ ) and yellow ( b ∗ ) were the dominant colors, with values of L ∗ ranging between 32.63 and 53.16. In general, our studies have shown that depending on the raw materials used, kimchi is a good source of dietary fiber but also vitamins and polyphenols.

Dry sheet food products or nori-like products can be produced from the mixture of Gelidium sp. and Ulva lactuca seaweeds, which is called geluring. Making geluring involves heat application that may influence the chemical composition of the product. The goal of this study was to evaluate the chemical characteristics of geluring by measuring proximate composition; dietary fiber, total phenolic, and flavonoid contents; and antioxidant activity(by DPPH analysis)of geluring and compare the values to those of the raw materials. Three types of geluring were prepared following commercial nori preparation procedures with some modifications: P1 (unseasoned), P2 (seasoned), and P3 (seasoned and roasted).The proximate composition of geluring products and raw materials differed significantly(P<0.05). Geluring fiber contents were not significantly different (P>0.05) among P1 (29.19±0.26%), P2 (29.42±0.66%), and P3 (29.83±0.11%), but these values differed significantly (P<0.05) from those of the raw materials. The total phenolic content, flavonoid content, and DPPH activity of P2geluringwere 1.38 mg GAE/g, 1.11 mg QE/g, and 61.23%, respectively, which were significantly (P<0.05) higher than those of P1 and P3 but lower than those of the raw materials. These results suggest that geluring processing might negatively impact the chemical composition of the products, but they still have high antioxidant activity and dietary fiber content and thus have potential for utilization as a functional food product.

Introduction. All over the world, natural medicine uses species of the genus Melilotus due to their anti-inflammatory, anti-rheumatic, analgesic, spasmolytic, astringent, diuretic and anticoagulant effects. In the Polish Pharmacopoeia, only the yellow melilot herb (Meliloti herba) has a monograph. Aim. The research was aimed at a comparative analysis of the content of the sum of polyphenolic compounds, including the sum of flavonoids and phenolic acids, and antioxidant activity in water extracts of M. officinalis and M. alba herb and root. Material and methods. The research was carried out for two species of Melilotus officinalis and M. alba. The raw material was herb and melilot root, collected during flowering period from natural sites. In aqueous extracts from raw materials, the following methods were determined by colorimetric methods: the sum of polyphenolic compounds using the Folin-Ciocalteu reagent, the sum of phenolic acids using the Arnov reagent, the sum of flavonoids using the Christ-Müller method and the antioxidant activity using the 2,2-diphenyl-1-picryl-radical hydrazyl (DPPH). Results. Meliloti alba herb has a much higher content of polyphenols, including phenolic acids and flavonoids than M. officinalis. In the yellow sweet clover the sum of polyphenols in the samples ranged from 2.101 to 2.438%, while in the white sweet clover from 2.765 to 3.540%. The content of phenolic acids in the samples of yellow sweet clover herb was 0.617-0.766%, and in the samples of white sweet clover herb was 0.646-0.900%. The content of flavonoids in the samples of yellow sweet clover herb ranged from 0.748 to 0.975%, and in the case of white sweet clover herb it was at the level of 0.801-1.192%. The samples of the commercial yellow sweet clover herb had the lowest content of phenolic compounds; the sum of polyphenols was 1.579%, phenolic acids 0.361%, and flavonoids 0.441%. The determined content of total polyphenols in the roots of both melilot species was low and amounted to 0.450% in MORA1 and 0.362% in MARA2. Despite the lower content of polyphenolic compounds (2.438%), the yellow melilot showed higher antioxidant activity (IC50 = 4.35 mg/ml) compared to the white melilot herb (IC50 = 5.31) with a higher content of polyphenols (3.010%). Conclusions. A higher content of the sum of polyphenols as well as phenolic acids and flavonoids was found in the white melilot. In both the yellow and white sweet clover herb extract, significantly more polyphenolic compounds were determined compared to the content in their root extract.
