Abstract:

The aim of the study was to contribute to scarce literature data on the content of selected vitamins and iodine in mare’s milk. The study focused on the content of selected lipophilic vitamins (A, E), hydrophilic vitamins B1, B2, B6) and iodine in milk samples obtained from 8 mares during 6 months of lactation. The content of micronutrients was evaluated according to the stage of lactation. Vitamins B2 and B6 were determined using ion-pair reversed phase high performance liquid chromatography with fluorescence detection, vitamin B1 by fluorescence detection by reversed-phase liquid chromatogra

The content of water-soluble vitamins was analyzed by HPLC. Both cooking and drying had a significant effect ( p<0.05) on the content of water-soluble vitamins of bulgur.

SUMMARYA study of the content of water soluble vitamins in the 12 baby milk formulae available in the UK in April 1983 showed that levels of vitamins in the individual brands were generally in excess of those declared by the manufacturer. For cows' milk based formulae the mean excess of vitamins over the declared level was 94%. Vitamin levels in prepared formulae averaged three times the minimum recommended level. The average level of B vitamins in prepared cows' milk based formulae was six times higher than in mature human milk. For the two soya based products, the levels of vitamins were gen

Abstract The article presents the results of the analysis of the content of vitamins in the meat of the African catfish Clarias gariepinus from the Clariidae family, which are widespread in the world’s industrial aquaculture. Studies have shown that African catfish meat contains water- and fat-soluble vitamins. Fat-soluble vitamins are represented by vitamins A and E. The group of water-soluble vitamins consisted of vitamins PP, C, and B vitamins (B1, B2, B5, and B6). Studies have shown that the meat of the studied fish species has a high biological value.

Abstract:

As the fourth largest staple crop in China, potatoes are a significant source of food and revenue, and provide diverse vitamins to human. However, the variation of vitamin retention in tubers after cooking were seldom evaluated. In this study, we evaluated the effects of steaming on water-soluble vitamins (vitamin B9 and vitamin C) and liposoluble vitamin (vitamin E) in tubers from eight potato cultivars grown in northern China. We found that these cultivars contained wide ranges of vitamin B9 (8.60–19.93 μg/100 g FW), vitamin C (46.67–155.44 mg/100 g FW), and vitamin E (15.34–33.82 mg/kg FW),

A reversed-phase high performance liquid chromatographic technique has been developed for the simultaneous quantitation of water soluble vitamins in 10 potent wild edible plants consumed by the tribal people of North-eastern region in India. The chromatographic separations of vitamins were assessed on Acclaim C18 column using a mobile phase of acetonitrile and aqueous trifluoro acetic acid solution with gradient elution. The experimental results exhibited that for different plants, the vitamin C content ranged between 0.15 ± 0.003 to 8.10 ± 0.03 mg/100g dry plant material (DPM). The vitamin B2

AbstractThe fat soluble vitamins, as well as n3 and n6 fatty acids (FA) are essential compounds of fish lipids and exclusively provided by the diet. Fish is sometimes eaten raw, but it is usually thermal processed before consumption. Temperature processing of fish tissue enhances its taste, inactivates pathogenic microorganisms and increases its shelf life. The fat soluble vitamins (vitamins A, D3 and E) and fatty acids are considered to be susceptible to oxidation during heating (cooking) process. The aim of the present study was to evaluate the effect of steaming (10 min at 90°C) and frying

Acerola is considered a superfruit, rich in vitamin C, phenolics, and carotenoids, and having a high antioxidant capacity. However, it is poor in oligosaccharides. Ultrasound technology can improve the bioavailability of several bioactive compounds, improving the nutritional content of several fruit juices. This work evaluated the use of ultrasound processing on acerola juice supplemented with fructooligosaccharides (FOS; 1% w/w) and its effects on the availability of vitamins, carotenoids, and phenolic content. The antioxidant capacity of the juice was correlated with its bioactive contents.

Background: Whole milk is a good source of all the nutrients, and it also contains a sufficient number of vitamins to permit regular the growth of the neonate.

In these circumstances, donkey milk can represent a good replacement for dairy cows’ milk in children affected by Cow Milk Protein Allergy (CMPA) because of its close chemical composition with human milk, mainly due to its low protein and low mineral content.
