Permintaan sayuran semakin lama semakin meningkat. Peningkatan permintaan sayuran harus diimbangi dengan produktivitas. Kangkung darat merupakan sayuran daun yang penting di kawasan Asia. Kandungan gizi kangkung cukup tinggi terutama vitamin A dan vitamin C. Saat ini teknologi plasma dapat digunakan dalam bidang pertanian. Plasma lucutan pijar korona merupakan sumber ion, elektron, dan radikal bebas. Udara bebas mengandung banyak gas yang tidak dapat  terserap langsung oleh tanaman. Radiasi plasma mampu mengionisasi gas dari udara menjadi bentuk ion yang ditembakkan dalam suatu bahan. Penelitian ini bertujuan untuk mengetahui pengaruh variasi waktu radiasi plasma terhadap viabilitas, laju perkecambahan dan laju pertumbuhan biji kangkung darat. Penelitian dilakukan di Laboratorium CPR (Center Plasma Research), Universitas Diponegoro. Rancangan penelitian yang digunakan adalah rancangan acak lengkap (RAL), dengan perlakuan perbedaan lama radiasi waktu 0, 10 menit, dan 20 menit dan pengulangan 3 kali. Parameter yang diamati viabilitas, vigor benih, dan laju perkecambahan tanaman kangkung darat. Analisis data menggunakan uji ANOVA dan uji lanjut duncan dengan taraf signifikasi 0.05. Perlakuan radiasi selama 20 menit, 10 menit dan kontrol memberikan hasil rata – rata viabilitas 87%; 73%; dan 53%, laju perkecambahan 2,1 n/hari; 2,1 n/hari; dan 2,08 n/hari  pada kangkung darat. Kata kunci : radiasi, plasma pijar korona, viabilitas, vigor benih

Latar Belakang. Anemia merupakan salah satu permasalahan gizi yang banyak terjadi di negara berkembang. Faktor gizi yang turut berkontribusi terhadap kejadian anemia diantaranya adalah kurangnya asupan zat gizi yang memengaruhi pembentukan Hemoglobin (Hb) pada penderita anemia. Tujuan. Penelitian ini bertujuan untuk mengetahui gambaran konsumsi energi, protein, zat besi, asam folat, vitamin C, vitamin A, dan seng pada subjek penderita anemia dibandingkan dengan angka kecukupan gizi (AKG) yang diduga menjadi faktor penyebab anemia. Metode. Penelitian ini menggunakan desain penelitian cross-sectional dan merupakan bagian dari penelitian “Observasi Klinik Formula Jamu Anemia” yang dilakukan pada bulan Maret-Desember 2018. Jumlah subjek sebanyak 83 orang dengan rentang usia 16-49 tahun. Data konsumsi makanan dikumpulkan dengan wawancara menggunakan food recall 24 jam dan selanjutnya dianalisis dengan program Nutrisurvey. Hasil. Hasil penelitian menunjukkan bahwa sebagian besar subjek memiliki status gizi normal. Tingkat konsumsi zat besi, asam folat, dan seng subjek kurang dari AKG, konsumsi energi dalam kategori cukup, dan konsumsi protein, vitamin A serta vitamin C lebih dari AKG. Hasil uji bivariat chi-square menunjukkan tidak ada korelasi yang bermakna antara status anemia dengan konsumsi zat gizi (p>0,05). Kesimpulan. Wanita usia subur (WUS) yang menderita anemia rata-rata memiliki tingkat konsumsi zat besi, asam folat, dan seng kurang dari AKG

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.

AbstractMaternal vitamin intake during pregnancy is crucial for pregnancy outcomes and the child's subsequent health. However, there are few valid instruments for assessing vitamin intake that address the effects of nausea and vomiting during pregnancy (NVP). This study aimed to investigate the validity of a FFQ concerning vitamin intake during early and late pregnancy with and without NVP. The participants comprised 200 Japanese pregnant women who completed the FFQ and from whom blood samples were taken in early and late pregnancy. Energy-adjusted dietary vitamin intakes (vitamin C, folate, vitamin B6, vitamin B12, vitamin A, vitamin E and vitamin D) from FFQ were compared with their blood concentrations. A subgroup of women with NVP was investigated. In early pregnancy, significant correlations between FFQ and biomarkers were observed for vitamin C (r0·27), folate (r0·18) and vitamin D (r0·26) in women with NVP and for vitamin A (r0·18), vitamin B12(r0·24) and vitamin D (r0·23) in women without NVP. No significant correlations were observed in either group for vitamins B6or E. In late pregnancy, similar significant associations were observed for vitamin C (r0·27), folate (r0·22), vitamin B6(r0·18), vitamin B12(r0·27) and vitamin A (r0·15); coefficients were higher among women without NVP. Our study demonstrates that the FFQ is a useful tool for assessing intake of several important vitamins in early and late pregnancy regardless of NVP status.

The potential of some indigenous fruits such as yellow-plum (Spondias mombin) and African Star Apple (Chrysophyllum albidum) remained largely untapped. These fruits can be processed and preserved in small-scale operations using simple techniques that could replace both expensive fruits and the lengthy operation processes usually used for jam production. Blends were produced from African Star Apple and Plum in the following proportion: 100:0%; 90:10%; 80:20%; 70:30%; 60:40% and 50:50% respectively to produce six African Star Apple and plum blends. The chemical properties and consumer acceptability of jams made from these blends were investigated using standard methods. Chemical analyses of the jam showed that vitamin A ranged between 613.09 and 686.04 (IU), sample with the highest percentage of African Star Apple had the highest value of Vitamin A; vitamin C ranged between 30.51 and 46.12 (mg/100 g); pH ranged between 4.29 and 4.58; Brix ranged between 11.00 and 14.97°Bx. There were no significant (p>0.05) differences in the sensory attributes of the samples. It was observed that Jam produced from African Star Apple and plum blend at 50:50% proportion had the highest Vitamin A and those at 90:10% proportion had the highest Vitamin C contents and all the samples were of high nutritional and health benefits.

In this study, we aimed to evaluate the effect of vitamins A, C, and E against aflatoxin B1 (AFB1) on blood cultures in relation to induction of sister chromatid exchange (SCE). The results indicated genotoxic and mutagenic damage in cultured human lymphocytes exposed to AFB1. The results showed that 5 μM concentration of AFB1 increased SCE. When vitamins A, C, and E were added to AFB1, the frequency of SCE decreased. These results suggest that vitamins A, C, and E could effectively inhibit AFB1-induced SCE, which may partially responsible for its mutagenic effect of AFB1. Besides, the protective effect of vitamins A, C, and E against AFB1 was increased in a dose-dependent manner (i.e., as the doses increased, their protective effects also increased). There was a significant decrease in the SCE frequency in AFB1-treated group compared with the groups receiving AFB1 and also vitamins A, C, and E. The most effective concentration was 100 microM vitamin C, and the lowest effective concentration was 0.5 microM vitamin A. Vitamin C has the most effective concentration of 100 μM, and vitamin A has the lowest effective concentration of 0.5 μM. The order of the decreasing effect of the SCE frequency of vitamins was as follows: vitamin C > vitamin E > vitamin A.
