The crystallinity index CI was estimated quantitatively, where the CI was defined as the ratio between the crystalline area and the total area covered by the curve, consisting of crystalline area and amorphous area of the region, according to the Eq.

These results are in agreement with those of Kuakpetoon and Wang that found lower pasting temperatures for different corn starches when oxi- dized, mainly at the concentration of 5.

The oxidative reaction promoted by NaClO results in partial glycosidic bonds disruption, lowering molecular weight that is reflected by starch paste viscosity decrease. The presence of bulky carboxyl groups, if compared with hydroxyl groups, weakens the granular structure of starch and contributes to lowering the paste viscosity Kuakpetoon and Wang ; Lawal et al. When the starch pastes are cooled, the starch macromo- lecules tend to re-associate due to hydrogen bonds formed between hydroxyls and as a result, the viscosity increase.

In the case of oxidized starch, this effect is restricted due to Fig. It is tive reactant presented a different behavior.

Braz J Food Technol ; 8 Micronutrients supplied by the product, especially iron, zinc, copper, vitamin A and vitamin C, may have also contributed to body growth, since they are involved in many anabolic reactions. Moreover, supplementation with multiple nutrients is more effective than single nutrient supplementation, as shown in a meta-analysis study carried out by Ramakrishnan et al.

J Nutr ; 10 The authors reported the effects of food supplement on the growth of children and adolescents in randomized controlled studies where combined nutrients were used, including vitamin A and iron. Similarly, Chagan et al. Effect on longitudinal growth and anemia of zinc or multiple micronutrients added to vitamin A: a randomized controlled trial in children aged months.

BMC Public Health ; Hieu et al. Multi-micronutrient-fortified biscuits decreased the prevalence of anaemia and improved iron status, whereas weekly iron supplementation only improved iron status in Vietnamese school children.

Br J Nutr ; 8 The improved iron status of children in the present study was superior to the results obtained in our previous study The effect of vitamin A fortification of sugar on iron metabolism in preschool children in Guatemala. Am J Clin Nutr ; 36 1 Hematological effect of supplementing anemic children with vitamin A alone and in combination with iron.

Am J Clin Nutr ; 48 3 The study of Bloem et al. Vitamin A intervention: short-term effects of a single, oral, massive dose on iron metabolism.

Am J Clin Nutr ; 51 1 The authors suggested that vitamin A has an effect on iron mobilization from reserves for hemoglobin synthesis, which increased iron absorption. The effect of vitamin A on iron mobilization from body reserves has been confirmed more recently by Zimmermann et al.

Vitamin A supplementation in children with poor vitamin A and iron status increases erythropoietin and hemoglobin concentrations without changing total body iron. Am J Clin Nutr ; 84 3 Jimenez et al. A single dose of vitamin A improves haemoglobin concentration, retinol status and phagocytic function of neutrophils in preschool children. Br J Nutr ; 6 Dietary inadequacy is associated with anemia and suboptimal growth among preschool-aged children in Yunnan Province, China. Nutr Res ; 31 2 The current study showed no correlation between product intake and serum retinol.

Geneva: Sight and Life Press; The study conducted by Zimmermann et al. It is known that vitamin A metabolites act on the genetic regulation of erythropoietin synthesis and other hormones and cytokines involving red blood cell production According to West Junior Vitamin A is also involved in the iron regulator protein-2 IRP2 , and consequently affects gene expression of ferritin and transferrin synthesis Vitamin A deficiency aggravates iron deficiency by upregulating the expression of iron regulatory protein Nutr ; 28 3 The composition of the product with respect to other nutrients, such as zinc, copper, and vitamin C, may have contributed to improve the iron status of preschool children in the present study.

This assumption is supported by Ash et al. Randomized efficacy trial of a micronutrient-fortified beverage in primary school children in Tanzania. Am J Clin Nutr ; 77 4 The test group showed significantly higher concentrations of serum ferritin and lower prevalence of vitamin A deficiency than the control group.

Hyder et al. J Nutr ; 9 After a 6-month intervention period, the test group compared with the control showed higher weight and height gains, higher concentrations of hemoglobin, serum ferritin and retinol, and lower prevalence of iron deficiency anemia.

Those who received a weekly iron supplementation showed an intermediate prevalence of anemia 7. The presence of other nutrients may improve iron absorption and metabolism Provision of multiple rather than two or fewer micronutrients more effectively improves growth and other outcomes in micronutrient-deficient children and adults.
