<abstract><title style='display:none'>Abstract</title>The present study is focused on the determination of optimized activity conditions of peroxidase (POD) of turnip (<italic>Brassica rapa</italic>). The enzyme is extracted from turnip with 0.5M Na2HPO4 (pH7.0). Peroxidase activity is evaluated by monitoring the oxidation of guaiacol to tetraguaiacol in the presence of hydrogen peroxide (H2O2). Before the optimization of peroxidase activity from a turnip by response surface methodology (RSM), a preliminary step is conducted for each studied parameter (pH, temperature, and NaCl concentration). Further, RSM following Box-Behnken design is used in order to refine the optimization of the conditions. Response surface analysis showed that parameter values with the highest peroxidase activity are 5.9, 29.8°C, and 1.07M for pH, temperature, and NaCl, respectively. Under these experimental conditions, peroxidase activity is found to be 4027.25U/mg. The obtained experimental value agrees with that of the calculated one, indicating the pertinence of the developed model for the optimization of peroxidase activity.</abstract>

The aim of this study is to enhance the use of <italic>Citrus limon</italic> peel by utilizing its essential oil as a natural aroma and preservative in fresh cream. The essential oil was extracted through hydrodistillation and analyzed using gas chromatography-mass spectrometry (GC-MS). The antioxidant and antimicrobial activities of the essential oil were assessed at varying concentrations prior to its incorporation into fresh cream. Subsequently, the antioxidant and sensory stabilities of the fresh cream were evaluated. The essential oils were characterized by a dominance of monoterpenes with a high limonene content (61%), oxygenated monoterpenes, sesquiterpenes and oxygenated sesquiterpenes. The essential oils effectively reduced the DPPH° radical, which was confirmed by the β-carotene bleaching assay. <italic>Debaryomyces sp. </italic>and <italic>Rhodotorula sp.</italic> showed sensitivity to the essential oils and have MICs of 0.25% and 0.5% respectively. However, <italic>Zygosaccharomyces sp1 </italic>and <italic>Zygosaccharomyces sp2</italic> were resistant. Their MICs were 1 and &gt; 4%, respectively. The TBARS test showed that fresh creams with <italic>Citrus limon</italic> essential oils were resistant to forced oxidation. Incorporation into fresh cream at 0.125 and 0.25% did not alter the flavor of the product, which did not differ from the control. From all results; we can conclude that lemon essential oil can be used as an antioxidant and aromatic agent in fresh cream.

This study aimed to quantify levels of the toxic heavy metals metalloid arsenic (As), cadmium (Cd), lead (Pb) and mercury (Hg) in commercially available noodles. Analysis was performed via the acid microwave digestion method followed by inductively coupled plasma mass spectrometry (ICP-MS). Furthermore, the potential health risks resulting from the consumption of noodles by polish consumers were evaluated using the estimated average daily intake of heavy metals (ADIHMs; µg·kg−1 bw·day−1). Additionally, to assess the potential health consequences due to noodle consumption, the total hazard quotient (THQ) and cancer risk (CR) were calculated. The average contents of Pb, As, Cd, and Hg in instant noodle samples were determined as 9.241, 8.483, 29.39, and 1.661 µg·kg−1, respectively. THQ values for heavy metal toxicity were found to be below 1, indicating that the consumer is not exposed to carcinogenic health risks associated with the analyzed metals. Additionally, the rank order of max THQ was Pb &lt; Cd &lt; As &lt; Hg, and the mean THQ was Pb &lt; Hg &lt; As &lt; Cd, while both the max and mean CR rank orders were Pb &lt; Cd &lt; As.

The aim of this study was to compare selected physicochemical properties, the fatty acid profile, and the content of vitamins A and E in plain yogurt (Y) made from cow’s (YC), goat’s (YG), and sheep’s milk (YS), and to monitor changes in these parameters within the shelf life of the analyzed products. The products were supplied by three manufacturers. Each group consisted of yogurts from three different batches, and each batch was represented by two products. The quality of the first product was analyzed in the middle of shelf life, and the quality of the second product was analyzed at the end of shelf life (E, last day). The products were stored at a temperature of 4○C until analysis. An analysis performed at date M demonstrated that YC had the highest (p ≤ 0.05) values of yellowness (b*) and titratable acidity, and the lowest (p ≤ 0.05) content of vitamins A and E; YG had the highest (p ≤ 0.05) values of redness (a*) and the lowest (p ≤ 0.05) value of b*; YS had the highest (p ≤ 0.05) values of lightness (L*) and pH, the highest (p ≤ 0.05) content of vitamins A and E, and the lowest (p ≤ 0.05) values of a* and titratable acidity. YC and YS were characterized by higher (p ≤ 0.05) values of chroma (C*) than YG. YC and YG were characterized by higher (p ≤ 0.05) values of UFA/SFA, MUFA/SFA, DFA/OFA, and n-6/n-3 PUFA ratios, compared with YS. The n-6/n-3 PUFA ratio was also higher (p ≤ 0.05) in YG than in YC. In comparison with YC, YG and YS had higher (p ≤ 0.05) values of the PUFA/SFA ratio and EFA concentrations, and the highest (p ≤ 0.05) values were noted in YS. Measurements conducted at date E revealed a decrease (p ≤ 0.05) in the value of a* and vitamin E content in YC, an increase in the value of L* in YG, and an increase in the value of a*, a decrease in the values of b*, C* and pH, and a decrease in vitamin E content in YS. Titratable acidity increased (p ≤ 0.05) in all types of Y. Changes in the nutritional value of fat (a decrease in the values of UFA/SFA, MUFA/SFA, and PUFA/SFA ratios, a decrease in EFA concentrations, and an increase in the n-6/n-3 PUFA ratio) were significant (p ≤ 0.05) only in YC. The results of the study indicate that YG was characterized by the highest stability, and YC was characterized by the lowest stability during storage.

The objective of this study was to compare the effects of extrusion cooking and roasting on the nutritional composition of the blend obtained from rice, soybean, millet and corn flours. Two different flour compositions with different proportions of ingredients were prepared. Roasting process was conducted at 160°C for a duration of 30 minutes, whereas extrusion cooking was performed at 129°C for approximately 5 minutes. Chemical analysis was carried out on all four samples. The findings revealed that the moisture and carbohydrate content in the extrusion-cooked samples (A and B) were higher than in the roasted samples (A’ and B’). In contrast, crude fat content, crude fiber content, and ash contents were higher in roasted samples (A’ and B’) compared to extrusion-cooked samples (A and B). The protein content of samples A, A’, B and B’ was found to be 10.67%, 8.47%, 14.64% and 9.18%, respectively. This proven protein content is higher in extruded composite flours (A and B). Additionally, calcium and iron contents were higher in the roasted samples, with sample B’ having the highest calcium and iron contents. Tannin content and phytic acid content was also higher in the roasted samples, with sample B’ having the highest tannin and phytic acid content. In conclusion, extrusion cooking increased nutritional content while reducing anti-nutritional components in the composite flour, suggesting its potential as a preferred processing method to maintain nutritional quality.

Wheat grain has health-promoting properties that are related to the content of phenolic acids in its composition, among which ferulic acid, syringic acid, p-coumaric acid and vanillic acid predominate acting as potent natural antioxidants. The study evaluated the phenolic acid (PA) content and grain yield of hybrid wheat genotypes (Hyland, Hywin) compared to the common variety (Patras), grown under an integrated system at two nitrogen rates of 60 (N60) and 120 (N120) kg·ha−1, under varying hydrothermal conditions during three growing seasons. The effects of genotype, cultivar and the interaction of cultivar and hydrothermal conditions on the phenolic acid profile, except for synapic acid, phydroxybenzoic acid and salicylic acid, and grain yield were confirmed in favour of the hybrid cultivars. The concentration of total phenolic acids (TPAs) and ferulic acid in the grain of the hybrid cultivar Hyland was higher and, in addition, greater yield stability of this cultivar under varying hydrothermal conditions was shown in the analysed years of the study. The grain of the common variety Patras was characterised by advanced content of p-hydroxybenzoic acid, and that of the hybrid variety Hywin by p-coumaric, caffeic and syringic acids. Higher TPAs content and lower grain yield of the varieties were observed in the 2018/2019 drought season. Higher nitrogen fertilisation (N120) compared to N60 significantly increased TPAs content and grain yield of Hyland and Hywin hybrid varieties. Fertilisation with N120 compared to N60 increased TPAs content by 4.2% and promoted higher concentrations of ferulic and syringic acids in the wheat cultivars tested.

Rhubarb (<italic>Rheum rhaponticum</italic> L.) is a valuable source of active components responsible for laxative, antibacterial, diuretic, anti-inflammatory and anti-cancer properties. On the other hand, ozone being an allotropic form of oxygen, due to its potential is a powerful antimicrobial agent. Treatment of rhubarb petioles with gaseous ozone, especially at a concentration of 50 ppm, for 30 minutes had a positive result on the microbiological stability and quality of the finished material. Sensory evaluation of prepared beers enriched without ozonated and ozonated rhubarb pulp showed that wheat beer with the addition of ozonated (50 ppm) rhubarb pulp was characterized by a balanced aroma and taste. The physico-chemical analysis of wheat beers demonstrated that the increasing concentration of ozone had an impact on, among others, increased the degree of final real attenuation (by 21.97%), decreased pH (by 18.43%) and energy value (by 36.30%), but had a negative impact on the content of ethyl alcohol (by 17.32%) compared to the control beer. Among the analyzed beers enriched with rhubarb, the beer product with the addition of ozonated (50 ppm) rhubarb was the most microbiologically stable. The research shows that wheat beers enriched with fragmented rhubarb can be a new trend to expand the range of wheat beers, and the use of gaseous ozone, especially at a concentration of 50 ppm for 30 minutes, can be a trend to extend the microbiological stability of beers, especially craft beers.

Rhubarb (<italic>Rheum rhaponticum</italic> L.) is a vegetable that, despite many health-promoting properties, contains large amounts of oxalic acid, which has a negative impact on human health. Treatment of rhubarb petioles with gaseous ozone is one way to improve their quality by changing their chemical properties. As part of the research, an analysis of the mechanical and chemical properties of rhubarb petioles was performed. The analyzes showed that the applied doses of ozone of 10 ppm during 1, 3 and 5 minutes lowered the concentration of oxalic acid during 5 days of tests performed after the ozonation treatment. The most favorable effect on the reduction of oxalic acid, amounting to 36%, was caused by gaseous ozone at a concentration of 10 ppm during 5 minutes compared to the control. In addition, it was noted that on the 1st and 3rd day after using ozone gas, the antioxidant activity of the tested raw material increased significantly. Also on the same days of testing, the total amount of polyphenols increased as a result of the use of ozone fumigation. The largest increase in the total amount of polyphenols, amounting to 12%, was observed for a dose of 10 ppm 5 minutes on the 1st day after the ozonation treatment compared to the control variant. In turn, no positive effect of the ozonation process on the content of vitamin C and the value of destructive force during three-point bending of rhubarb leaf petioles was noted.

Modification of the Intensity of Compounds Biosynthesis in the Petioles of Rhubarb (<italic>Rheum rhaponticum</italic> L.) Induced by the Ozonation Process

<abstract><title style='display:none'>Abstract</title> The quality of cereals is very important for both human and animal nutrition. Fusarium mycotoxins include a great number of compounds. Trichothecenes, zearalenone (ZEN) and fumonisins are the major Fusarium mycotoxins occurring in cereal grains, animal feeds and forages. Conditions that predispose to mycotoxin production by Fusarium species include humidity, temperature, aeration and substrate type. Even if a great number of fungal metabolites have been designated as mycotoxins, a small number are known to have significant animal/human health and economic significance. For this, the world-wide impact of mycotoxins on human and animal health is likely underestimated and the future in this area is to identify additional specific biomarkers and group of biomarkers that can be used to establish the exposition of human and animals to individual mycotoxins.</abstract>

<abstract><title style='display:none'>Abstract</title>The objective of the present study was to standardise the duration and temperatures of the conventional oven drying methods for best physical and sensory characteristics of dried tomato. The experiment consisted of two factor factorial design (3*2) with three levels of drying temperature (70°C, 80°C and 90°C) and two levels of drying duration (7 and 8 hours) with three replications. An improved and high yielding variety (Cochoro) of tomato released in 2007 for processing and widely grown in <italic>Ziwai</italic> (Maki), Ethiopia was used. Prior to drying, individual tomato fruits were washed and sliced into uniform thickness (8mm); then, the slices were placed on to the drying trays in a single layer to facilitate uniform drying in hot air oven set at predetermined temperatures per the respective treatments. Data were collected on different physical and sensory attributes and analysed using SAS software (version 9.2). The results showed that titratable acidity, total soluble solids and water absorption capacity were significantly (p≤0.001) increased due to the interaction of degree of temperature and duration of oven drying. In contrast, pH and water activity decreased as the drying temperature and duration increased. Drying at 70°C for 7 hours produced dried tomatoes with the highest sensorial acceptability and physical attributes while higher temperatures (80, 90°C) and longer duration (9 hours) significantly detract the quality of dried tomato. Hence, it is possible to add value and preserve tomatoes through oven drying at the right temperature and optimum duration.</abstract>
