Optimization for enhanced phytase production by Aspergillus oryzae SBS50 in submerged fermentation was investigated using Taguchi design. In first step design, starch, beef extract, magnesium sulphate, ferrous sulphate and Tween 80 were identified as significant factors affecting phytase production. These significant factors were further optimized at four different levels using a second Taguchi...

An evaluation was made into the usefulness of ferrous fumarate as an iron fortificant for an experimental chocolate drink powder targetted to children and adolescents. Organoleptically ferrous furmarate was acceptable when the chocolate drink powder was reconstituted in milk or water that was heated to less than 80 degrees. Unacceptable colour changes occurred, however, when boiling milk or wat...

Ferrous fumarate (Fersamal) and ferrous carbonate (Ferrodic) may produce false-positive results with the orthotolidine tablet tests (Occultest and Hematest) if administered to patients being investigated for alimentary bleeding. Misleading results are also likely if the benzidine test is employed as a filter-paper procedure. Ferrous sulphate, gluconate, succinate, iron and ammonium citrate, and...

Iron deficiency and related iron deficiency anaemia (IDA) are the most prevalent nutritional disorders worldwide. The standard treatment involves supplementation with solid or liquid iron supplement preparations, usually based on a ferrous salt such as ferrous sulphate, ferrous fumarate, or ferrous gluconate. In the present study, we compared iron uptake and absorption from various solid and li...

Radiolabelled tablets of slow-release iron and ferrous sulphate containing 50 mg of elemental iron were given to 28 patients, and iron absorption was studied using a whole body counter.There was no significant difference between the absorption of ferrous sulphate and that of slow-release iron in normal subjects, anaemic patients, anaemic and non-anaemic post-gastrectomy patients, or those with ...

Allergies to iron salts are seldom reported. We studied a patient with iron-defi ciency anemia who had suffered anaphylactic reactions caused by oral iron salts. An allergy study was performed using single-blind, placebo-controlled oral challenge and skin tests with various iron salts as well as excipients in commercial formulations. Oral challenges were positive for 2 of the commercial formula...

In a double-blind trial the response to treatment with Ferro-Gradume (a slow-release preparation of ferrous sulphate) has been compared in the same individuals with the response to ferrous fumarate in a single daily dose regimen using a similar dose of iron. No significant difference was found in the therapeutic response or in the incidence of side-effects between the two preparations.

Introduction: Increased iron requirements to supply the expanding blood volume of the mother and the rapidly growing fetus and placenta can cause iron deficiency anemia.Plenty of oral iron formulations are available.A comparative study was planned to find out the best oral iron supplement for improving iron deficiency anemia in pregnant females as well as to compare their tolerability, as this ...
