Abstract Red dragon fruit (Hylocereus costaricensis) is a famous fruit because of its high nutritional content. Although the product diversification of red dragon fruit is quite a lot, however, this product has limited information as a syrup product. The evaporation process for making syrup at the traditional level is usually carried out at high temperatures which results in the high destruction of nutritional content and reduces the quality of syrup. The study of the evaporation process at low temperature and low pressure using a double jacket vacuum evaporator for manufacturing red dragon fruit syrup was conducted in this research in order to improve product quality. The aims of this study are to evaluate the effect of temperature process and vacuum pressure on the quality of red dragon fruit (H.costaricensis) syrup using a double jacket vacuum evaporator and to know the optimum temperature process and vacuum pressure to producing red dragon fruit sirup with higher content of vitamin C. The double jacket evaporator operates at a pressure lower than atmospheric pressure so that there were 9 treatment combinations. The result showed the temperature gave a highly significant effect, especially on vitamin C. It also gave on moisture content and reducing sugar. The temperature gave no significant effect on total sugar content. Whereas, the pressure gave a significant on moisture content, but not gave a significant on vitamin C, reducing sugar content and total sugar content. However, the best treatment for optimum vitamin C is 50 0C/-60 cmHg with 8.75 mg/100 ml.

The study was concerned with the chemical composition of two varieties hog-plum Pulp collected from Mymensingh and Barishal and developed jelly and leather. Cabinet dryer, model OV-165 (Gallen Kamp Company) was used for dehydration of two types of hog-plum pulp and leather. The fresh and dried hog-plum and hog-plum products were analyzed for their moisture, ash, vitamin-C, pH, total soluble solids and sucrose contents. The moisture content, ash, vitamin C, pH, total soluble solid (TS), reducing sugar and non-reducing sugar of Barishal hog-plum’s was 83.84% (wb), 0.81% , 33.00 mg/100g, 2.62, 8.5%, 5.02% and 1.6% respectively; Mymensingh hog-plum’s was 86.69% (wb), 0.78%, 30.90 mg/100g, 2.7, 6.5%, 4.7% and 1.3% respectively. The chemical composition of Mymensingh and Braishal hog-plum showed that Barishal hog-plum contained higher solid content, ash, Vitamin C than Mymensingh hog-plum. It was found that Barishal hog-plum had higher flesh (67.59%) than Mymensingh hog-plum (62.60%). The chemical composition of hog-plum leather was analyzed for moisture, Ash, Vitamin C, TS, Titrable acidity, total sugar and protein content. The ash and sugar content of developed leathers from Barishal and Mymensingh hog-plum was very similar but the vitamin C content for developed products was very low. It was also found developed products contained higher amount and sugar and protein. It was found that the chemical compositions of developed jelly were more or less similar to the fresh hog-plum; only the vitamin C was decreased significantly. These studies indicate that, developed products viz. lather and jelly would contain significantly higher amount of nutrients and energy then the fresh fruits. Organoleptic taste testing using 1-9 hedonic scale showed that jelly made from mechanically dried Mymensingh hog-plum was the most acceptable product and was ranked as “like very much”. Leather made from Mymensingh hog-plum (pulp+4.5% sugar+ 0.15% KMS) was the best among other samples and was ranked as “like very much”.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14598 J. Environ.

Background. Vitamin C, E, D, A, zinc are considered to be essential in preventing and treating of acute respiratory infections (ARI) including COVID-19. Methods. We reviewed published studies evaluating the potential roles of these vitamin and zinc for ARIs and COVID-19 using Medline database, medRxiv, and bibliographic references. Results. Vitamins C, D, and E did not reduce incidence of common cold in general, but vitamin C reduced by half in population with physical and environment stresses. Vitamins C and E shortened duration and reduced severity of common cold. A large-dose vitamin A had no effect on recovery from pneumonia. Zinc improved clinical deterioration and pneumonia duration in under five. The effect on preventing COVID-19 morbidity and related-death was lacking. Conclusions. Although the effects of vitamins and zinc on ARIs including COVID-19 were inconclusive, taking these for a short period during pandemic may be beneficial when there is risks of deficiency.

The aim of our study was to analyse vegetables, potatoes and their products as sources of energy and nutrients in the average diet in Poland. Representative data of the 2016 Household Budget Survey from 36,886 households were used. This is the largest study sample in Poland, so we generalized the conclusions to the whole population using the statement ‘average diet’. We analysed three main product groups: vegetables, vegetable products, and potatoes and potatoes products, dividing them into 14 subgroups (e.g., tomatoes, cabbage, carrots, other vegetables, and mushrooms). The percentages of energy, protein, carbohydrates, total fat, nine vitamins (thiamine, riboflavin, niacin, vitamin B6, folate, vitamin C, vitamin A, vitamin D, and vitamin E), seven minerals (calcium, phosphorus, sodium, potassium, iron, magnesium and zinc), and fibre from the analysed food subgroups are presented. Additionally, the influence of household characteristics on the supply of energy and nutrients from each subgroup of vegetables, potatoes, and their products was evaluated using cluster analysis. In the analysis, R programme and Kohonen neural networks were applied. Our study showed that vegetables, potatoes, and their products provide 7.3% of daily dietary energy supply. Vegetables contribute more than 20% of the supply of six nutrients: vitamin C (51.8%), potassium (32.5%), folate (31.0%), vitamin A (30.6%), vitamin B6 (27.8%), and magnesium (20.2%), as well as fibre (31.8%). Cluster analysis distinguished three clusters that differed in nutritional supply from vegetables, potatoes, and their products. Educational level, income measured by quintile groups, village size, socio-economic characteristics, urbanization degree, and land use were the most important factors determining differences between clusters.

Tetrapleura tetraptera is widely cherished in African traditional homes because of its alleged therapeutic and nutritional properties. This present study aimed at determining the levels of vitamin A, C, E, and beta-carotene and trace element (Fe, Cu, Mn, Co, Se, and Zn) concentrations and their extractabilities in the pulp, seeds, and whole fruit (mixture of pulp and seeds) of T. tetraptera. The total trace element concentration of Fe, Cu, Co, Mn, and Zn and their extractabilities (%) were determined using flame atomic absorption spectrometer (FAAS), whereas UV-VIS spectrophotometer was used to determine selenium concentration. The trace element content (mg/kg) based on dry weight in the pulp, seeds, and whole fruit was Fe (162.00 ± 7.14, 115.00 ± 12.00, and 154.00 ± 25.20, respectively), Zn (31.60 ± 4.77, 43.40 ± 5.29, and 41.50 ± 8.97, respectively), Cu (16.10 ± 4.98, 11.90 ± 8.40, and 17.20 ± 14.50, respectively), Mn (55.30 ± 2.41, 156.00 ± 10.20, and 122.00 ± 5.29, respectively), Co (38.10 ± 6.40, 21.10 ± 7.15, and 44.00 ± 14.90, respectively), and Se (1.49 ± 0.17, 2.43 ± 0.28, and 2.97 ± 0.27 μg/g, respectively). The mineral extractabilities (%) in the pulp, seeds, and whole fruit of T. tetraptera were established to be in the order Co > Zn > Fe > Cu > Se > Mn. Also, the chromatographic method (HPLC) was used to evaluate vitamin E concentration, and vitamin C and concentration of beta-carotene were calculated from the obtained concentration of vitamin A using a conversion factor by the titrimetric method. From the results of vitamin analysis, a significant difference (p<0.05) was observed among the pulp, seeds, and whole fruit for vitamin C and E. However, no significant difference (p>0.05) was perceived among these plant parts for vitamin A and beta-carotene. This study has therefore revealed that the pulp, seeds, and whole fruit of T. tetraptera contain varying concentrations of vitamins and trace elements and has given many vital insights on which part of T. tetraptera to consume, as concentrations of these nutrients differ in the discrete parts of the fruit.
