Manufacture and quality of iron-fortified yogurt.
Yogurts (nonfat and low fat) were manufactured and fortified with 10, 20, and 40 mg of iron/kg of yogurt. Growth of starter culture bacteria and nonstarter culture bacteria as well as lipid oxidation of the yogurts were monitored over 30 d of storage at 4 degrees C. Sensory characteristics of the yogurts were determined during that time by a trained panel of judges, and consumer panels were use...
متن کاملPurification of Floodwater by Electrolysis
An adequate supply of pure water is absolutely essential to human existence. During floods, water is available in adequate quantity, but the quality is often not suitable for drinking or cooking purposes. The goal of the study was to develop an easier, cheaper and faster technique of water purification. Oxygen ions are well known for their high reactivity. An attempt has been made to use oxygen...
متن کاملUsing Taguchi Method to Optimize Recovery of Bismuth by Electrolysis
This paper presents a methodology, based on the taguchi parameter design approach, for the optimization of process parameters for bismuth recovery from aqueous solutions. The process parameters considered are [Bi3+], [NaCl], temperature, and cathodic current density. In addition, cell voltage and current efficiency as two responses have been considered. An orthogonal array L9, the signal-to-noi...
متن کاملAnomalous Heavy Atomic Masses Produced by Electrolysis
By applying to electrolysis cathodes a technique that produces essentially only oxides that are volatile at room temperature, spectroscopically determined masses between 222 and 351 are found that cannot be ascribed to known compounds. In particular the masses found between 231 and 240 AMU cannot be ascribed to random signals but do correspond to CO2 the carbon of which is a neutron-rich nuclid...
متن کاملHydrogen Production by Alkaline Water Electrolysis
Water electrolysis is one of the simplest methods used for hydrogen production. It has the advantage of being able to produce hydrogen using only renewable energy. To expand the use of water electrolysis, it is mandatory to reduce energy consumption, cost, and maintenance of current electrolyzers, and, on the other hand, to increase their efficiency, durability, and safety. In this study, moder...
