Microemulsions prepared by using either sodium dodecyl sulfate (SDS) or trimethyltetradecylammonium bromide (TTAB) were tested with regard to the migration time, selectivity and number of theoretical plates using a set of both water-soluble and lipid-soluble vitamins. While in the separations where SDS was used as the surface-active agent for microemulsion preparation, better resolutions were o...

A reversed-phase high-performance liquid chromatographic procedure has been developed for determination of water-soluble vitamins (ascorbic acid, niacin, panthothenic acid (vitamin B5), pyridoxine (vitamin B6), thiamine (vitamin B1), folic acid, and riboflavin (vitamin B2)) in tarhana samples, a traditional Turkish cereal food. Sample-treatment entails SPE with Sep-Pak C18 (500-mg) cartridges. ...

whey contains more than half of total solids present in the original milk, which includes 20% of the proteins, most of the lactose, minerals and water soluble vitamins. in this study, selective separation of whey components by aphron flotation (separation of ultrafine particles by micro-bubbles) has been investigated. it has been shown that it is possible to recover valuable components of whey ...

Hypertension affects populations globally and is thus a public health and socio-economic problem. Macronutrient and micronutrient deficiencies are common in the general population, and may be even more prevalent in hypertensive patients. This study aimed to determine a possible association between hypertension and intake of fat-soluble vitamins A, D and E. Participants were from the cross-secti...

CONTEXT Vitamins B1 (thiamine), B3 (niacin), B6 (pyridoxine), and C (ascorbic acid) are vital for energy, carbohydrate, lipid, and amino acid metabolism and in the regulation of the cellular redox state. Some studies have associated low levels of water-soluble vitamins with metabolic syndrome and its various components. AIMS This study aims to determine the plasma concentrations of vitamins B...

Vitamins are essential for a healthy life. Compared to other nutrients, the body needs them in very small amounts. B vitamins, often known as vitamin complex, class of water-soluble vitamins with key functions cellular metabolism. Thiamine (vitamin B1), riboflavin B2), niacin B3), pantothenic acid B5), pyridoxine B6), biotin B7), folate B9), folic acid, and cobalamin B12) eight distinct that co...

The article draws attention to the fact that vitamin feed additive Introvit A+WS is an effective complex in its composition, consisting of 12 fat-and water-soluble vitamins, 18 essential and replaceable amino acids 9 macro-and microelements affect not only stability various infectious diseases, but also increase meat productivity young poultry. In recent years, industrially produced vitamins ha...

The advances made in the purification of the vitamins have provided an improved method of approach toward the study of the number, as well as nature, of the essential food factors. Because of the uncertain composition of the vitamin B complex, it is as yet very difficult to test for additional water-soluble components of the ultimate purified diet. The fat-soluble group, however, appears less c...
