Jul 23, 2001 Legumes are a good source of calcium, iron and zinc, but are also a source of phytates and dietary fibre components that can negatively affect the bioavailability of these minerals. To estimate the latter, an in vitro dialysis method can be applied that gives the dialysability of a mineral as an estimate of its availability for absorption.
Calcium impregnation is used as a pretreatment in the processing of papaya in syrup. The effect of process temperature 30 and 45 C, calcium source calcium gluconate and calcium lactate, calcium concentration 0.5 and 1.5 ww, and pH 4.2 and 6 were studied. The mineral source affected significantly the calcium uptake and the fruit firmness, and therefore, the product quality maximum ...
Deciencies of micronutrients, especially minerals such as iron, zinc, and calcium, are widespread in developing countries such as China, and this area is a cause for concern. Although many factors including inadequate dietary intake of these micronutri-ents are responsible for the onset of iron and zinc deciencies,
It is against this background that this research was conducted to determine the effect of some processing methods on the antinutrients soluble and total oxalates, toxic substances cyanide and nitrate and some micronutrients which include vitamin C, -carotene provitamin A and mineral elements Fe, Mg, Zn, Na and K in Hibiscus sabdariffa ...
Mar 01, 2004 The present work evaluates the effect of lime concentration 0, 1.2, 2.4, and 3.6 and cooking times 45, 60, and 75 min on phytic acid retention of whole maize, its endosperm, and germ, as well as on the content of calcium, iron, and zinc on the same samples.
Feb 04, 2004 The present work evaluates the effect of lime concentration 0, 1.2, 2.4, and 3.6 and cooking times 45, 60, and 75 min on phytic acid retention of whole maize, its endosperm, and germ, as well as on the content of calcium, iron, and zinc on the same samples.
Micronutrients play an important role in increasing legume yield through their effect on the plant itself, nitrogen fixing symbiotic process and effective use of major and secondary nutrients. Among micronutrients, cobalt, boron, molybdenum and zinc are essential for the growth of Rhizobium Corresponding authors e-mail drdhar20012gmail.com
Jan 31, 2013 Every year more than 20 million infants are born with low birth weight worldwide. About 3.6 million infants die during the neonatal period. More than one third of child deaths are thought to be attributable to maternal and child under nutrition. To systematically review the effect of supplementing various combinations and types of micronutrients on the course and outcomes of pregnancy.
Dec 15, 2016 It is clear that processing left positive effect on percent ionizable iron. It might be due to release of iron from the protein-iron-phytate complex during roasting. Heating may have a direct effect on protein matrix through denaturation, and this may result in a different proteolytic pattern with release of peptides with altered iron-binding ...
Most of the vitamins are also lost in the process. There is a 90 percent loss in vitamin B1,75 percent in B2 and less than 50 percent of the niacin is retained. Papa seca, vitamins the best. There is an increase in the iron, calcium and phosphorus content in all the preparations Table 6.3 because of the increased concentration of the product.
Nearly every food preparation process reduces the amount of nutrients in food. In particular, processes that expose foods to high levels of heat, light, andor oxygen cause the greatest nutrient loss. Nutrients can also be washed out of foods by fluids that are introduced during a cooking process.
Apr 29, 2021 The micronutrients magnesium, zinc, calcium, iron, and niacin are discussed most extensively. In short, it appears that both types of stress affect magnesium and zinc negatively and also have an effect on calcium and iron. Physical but not emotional stress resulted in elevated excretion of niacin metabolites, which was supported by only one study.
Apr 09, 2021 Iron transporters are present in the cecum and right colon, and, in the presence of prebiotics that promote growth of bacteria to produce propionate, iron absorption increases . Luminal minerals, including calcium, iron, and other micronutrients, may also have microbiome-modulating effects as well . As discussed, bacteria present different ...
Jun 27, 2018 To enhance iron and zinc bioaccessibility in pearl millet, a proper understanding of the effect of various processing technologies on the reduction of inhibitory factors is required. The above strategy could help in addressing the issue of micronutrient deficiency to a great extent.
Effect of a micronutrient fortificant mixture and 2 amounts of calcium on iron and zinc absorption from a processed food supplement. Concepcion Mendoza, Janet M. Peerson, Kenneth H. Brown, Bo L nnerdal. Endocrinology, Diabetes, and Metabolism Research output Contribution to journal
Dec 10, 2013 In addition to these macro and micronutrients, plantbased foods contain significant levels of phytate, which inhibits absorption of minerals, especially iron, calcium, and zinc. 6 Maize contains 49 gkg of phytate, depending on the variety 7, 8 and also contains about 5

Jul 01, 2017 Various processing methods like cooking and blanching reduce the levels of some of these harmful and antinutrient substances in vegetables 4, 5. Little is known about the effect of processing on the mineral composition of species like M. oleifera, H. canabinum, S. nigrum, C. maxima and V. calvoana.
The bioavailability of key minerals such as iron, zinc and calcium is known to be significantly affected by the fiber, phytic acid, and tannin content of foods. Concentrations of these constituents are altered by various processing methods including milling, fermentation, germination sprouting, extrusion, and thermal processing.
There was no significant effect of dietary calcium on iron absorption. Zinc absorption was not associated with the form of zinc consumed, but higher dietary calcium was marginally associated with lower zinc absorption P 0.071.
Studies on human subjects have shown that calcium Ca can inhibit iron Fe absorption, regardless of whether it is given as Ca salts or in dairy products. This has caused concern as increased Ca intake commonly is recommended for children and women, the same populations that
Household processing such as heat treatment, sprouting, fermentation and malting have been evidenced to enhance the bioavailability of iron and -carotene from plant foods. Food acidulants amchur and lime are also shown to enhance the bioavailability of
