Results: The absorption of iron from the NaFeEDTA-containing (novel) food product was 1.7 times that from the ferrous sulfate-containing (standard) product (P = 0.015). 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).

Pearl millet minerals: effect of processing on ...

27/06/2018  Phytic acid forms complex with minerals (such as iron, zinc and calcium), and becomes insoluble at the physiological pH of the intestine. Hence it reduces the uptake of the above essential dietary minerals in the human gut. In humans, inhibition of iron, zinc and calcium absorption by phytic acid is dose-dependent (Brune et al. 1992).

In contrast, the negative effect of calcium on iron absorption has not been confirmed in long-term supplementation studies. Ascorbic acid has a strong iron absorption promoting potential and in iron deficient populations ascorbic acid supplementation improves iron status. Thus, ascorbic acid supplements or an increased intake of ascorbic acid rich foods could have important public health implications, especially in populations subsisting on a mainly plant food based diet. The effect

may therefore impose a risk of reduced iron utilisation. Calcium interactions An absorption depressing effect of calcium on iron absorption has been clearly demonstrated in single-meal studies and short-term diet intervention studies (Hallberg et al. 1991). An addition of 150 mg of calcium to bread or a hamburger meal reduced iron absorption by 50 %. The

The Impact of Food Processing on the Nutritional Quality ...

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.

23/07/2001  Traditional and microwave cooking reduced the mineral contents by 9.7–36.4% for calcium, 14.2–31% for iron and 11.1–28.9% for zinc. The dialysabilities of calcium with respect to the values for the raw products were also reduced by these cooking techniques. Industrially processed legumes had higher dialysabilities of calcium, iron and zinc than traditionally or microwave cooked legumes.

Deficiencies 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 deficiencies, their poor bioavailability from plant foods is probably the most likely ...

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% w/w), 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 ...

Nutritional Effects of Food Processing – NutritionData

Freezing, Drying, Cooking, and Reheating. Nearly every food preparation process reduces the amount of nutrients in food. In particular, processes that expose foods to high levels of heat, light, and/or oxygen cause the greatest nutrient loss. Nutrients can also be "washed out" of foods by fluids that are introduced during a cooking process.
