The purpose of this study was to determine the possibility of using a chokeberry juice concentrate as a component of osmotic solution and convection-microwave-vacuum drying applying to obtain dried pro-health-promoting strawberries. The research material was Honeoye strawberries, which were dehydrated in sucrose and sucrose with chokeberry juice concentrate addition, and then subjected to microwave-convection-vacuum or freeze-drying. Analyses were conducted to determine the influence of the applied processes on vitamin C content, total polyphenols, antioxidant activity, and sensory properties in dried fruit. Study results confirmed the possibility of using a chokeberry juice concentrate as a component of the osmotic solution, especially with regard to polyphenolics content and antioxidant activity. In addition, convection-microwave-vacuum drying was shown to be a promising technology for the production of dried strawberries, with high pro-health potential and acceptable sensory qualities.

Kowalska, Joanna,Lis, Monika,Biesaga, Magdalena Occupational Safety and Health Research Institute 2021 Safety and health at work Vol.12 No.2

Background: The article presents the results of studies performed in order to develop a new method of airborne potassium bromate(V) determination at workplaces. Methods: The method is based on a collection of the inhalable fraction of potassium bromate(V) using the IOM Sampler, then extraction of bromates with deionized water and chromatographic analysis of the obtained solution. The analysis was performed using ion chromatography with conductometric detection. The tests were performed on a Dionex IonPac®AS22 analytic column (250 × 4 mm, 6 ㎛) with AG22 precolumn (50 × 4 mm 11 ㎛). Results: The method provides for potassium bromate(V) determination within the concentration range of 0.043 ÷ 0.88 mg/m³ for an air sample of 0.72 m³ in volume, i.e., 0.1-2 times the exposure limit value as proposed in Poland. The method was validated in accordance with PN-EN 482. The obtained validation data are as follows: measuring range: 3.1-63.4 ㎍/mL, limit of detection (LOD) = 0.018 ㎍/mL and limit of quantification (LOQ) = 0.053 ㎍/mL. The developed method has been tested in the work environment, on laboratory employees having contact with potassium bromate(V). Conclusion: The analytical method allowed the determination of the inhalable fraction of airborne potassium bromate(V) at workplaces and can be used to assess occupational exposure.

Monika Chuda-Kowalska,Andrzej Garstecki 국제구조공학회 2016 Steel and Composite Structures, An International J Vol.20 No.1

Polyurethane foam with low density used in sandwich panels is examined in the paper. A series of experiments was carried out to identify mechanical parameters of the foam. Various experimental methods were used for determining the shear modulus, namely a four and three point bending tests (the most common in engineering practice), a double-lap shear test and a torsion test. The behavior of PU in axial compression and tension was also studied. The experiments revealed pronounced anisotropy of the PU foam. An orthotropic model is proposed. Limitations of application of isotropic model of PU in engineering practice is also discussed.

Diet is regarded as one of the important environmental factors triggering inflammatory bowel disease (IBD). Many IBD patients avoid numerous types of foods in fear of disease exacerbation. The aim of the study was to investigate dietary beliefs and food avoidance among pediatric patients with IBD. This questionnaire-based study was conducted in three University-affiliated children's hospitals in Poland. Data were collected from parents of children who were diagnosed with IBD. A total of 155 parents of IBD patients participated in the survey: 104 (67.1%) had a child with Crohn's disease and 51 (32.9%) with ulcerative colitis. Parents of older children and those with longer disease duration predicted diet being considered one of the causative agents of IBD, and differences were statistically significant (P = .01 and P = .04, respectively). Also, patients with a shorter history of disease rarely shared food with other family members (P = .02). In total, 61.5% of patients avoided some kind of food in fear of disease flares. In the parent's opinion, the food the children liked but avoided included fried dishes, sweets (e.g., chocolate, cookies, cakes, candies, jellies), and fast food. Due to their dietary beliefs, parents of children with IBD commonly introduced dietary restrictions for their offspring. Frequent and unjustified food avoidance may influence not only nutritional status but also general well-being of pediatric patients. Our results underscore the urgent need for IBD patients and parents of ill children to receive reliable dietary advice based on strong scientific evidence.

In traditional Korean medicine, lotus (Nelumbo nucifera Gaertn) roots have been used as an antidiabetic and an antiproliferative remedy. However, scientific publications on lotus properties are very limited. Therefore, it was decided to investigate the Korean white lotus cultivars in order to find out their bioactivity. It was found that all lotus cultivars (Inchisa, Muan, Garam, and Chungyang) possess high amounts of bioactive compounds: total phenols, between 7.95±0.8 and 4.21±0.3mg of gallic acid equivalents (GAE)/g dry weight (DW); ascorbic acid, between 15.8±1.1 and 22.3±1.7mg of ascorbic acid/g DW; and amino acids, between 15.05±0.82% and 16.62±0.90% DW. The highest contents of polyphenols (7.95±0.8mg of GAE/g DW) and the highest levels of antioxidant [by 2,2-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) and 1,1-diphenyl-2-picrylhydrazyl assays, 54.27±6.1 and 21.98±2.5μM Trolox equivalents/g DW, respectively] and antiproliferative activities on both human cancer cell lines (Calu-6 for human pulmonary carcinoma and SMU-601 for human gastric carcinoma, 59.75±3.99% and 71.21±2.79% cell viability, respectively) were found in the Chungyang cultivar. Fluorometry and Fourier transform infrared spectroscopy can be applied as rapid methods for determination of bioactive compounds, such as polyphenols. The correlation between the bioactive compounds and the antioxidant activity was high. In conclusion, all Korean white lotus cultivars are valuable medicinal foods, and in order to receive the best results a combination of lotus cultivars has to be consumed.

Exclusive Enteral Nutrition Remission Induction Treatment Influence on Transient Hypertransaminasemia in Children with Newly Onset Crohn's Disease

Agata Wasilewska,Katarzyna Ponanta-Gawron,Beata Burtan,Beata Burtan,Charissa Stephen Chandra Sagaran,Mariusz Duplaga,Kinga Kowalska-Duplaga 한국식품영양과학회 2022 Journal of medicinal food Vol.25 No.4

Pediatric Crohn's disease (CD) is commonly associated with hepatobiliary complications, including transient liver enzymes elevation (LEE). Exclusive enteral nutrition (EEN) is recommended as primary treatment in mild-to-moderate pediatric CD. Data concerning EEN and liver enzymes (LE) abnormalities are limited. The aim of this study was to assess the LEE occurrence in newly diagnosed CD pediatric patients during EEN. Retrospective analysis of 73 patients, with no previous signs of liver disease, qualified to EEN. LE were assessed at diagnosis, during EEN, after completion of the nutritional treatment, and reintroduction of free diet. Thirty-one (42%) children presented with LEE and 28 (38%) with transient LEE. The LEE cohort presented with higher percentage of protein energy (24.0% ± 29.4 IQR [interquartile range] vs. 18.6% ± 23.6 IQR, P < .05) versus nonprotein energy (fat and carbohydrates) in total energy intake (75.9% ± 29.4 IQR vs. 81.4% ± 23.6 IQR, P < .05). Also, the protein/energy ratio was higher in the LEE group compared with the group with normal LE (0.026 vs. 0.024, P = .028). At the fourth week of EEN, aspartate aminotransferase elevation correlated with higher daily protein intake (P < .018). The LEE during EEN is typically a low-grade and transient condition that may be connected to applied treatment. We hypothesize that higher protein/energy ratio during EEN may be associated with mild, temporary LEE. Careful observation with repeated measurement of LE activity may be sufficient proceeding in patients without any other symptoms of CD-associated liver disease.
