Aluminium phosphate was purchased without any approval of the concerned department.
It has been attributed to increased charge repulsion between P ions and surface negative charges, to increased concentration of solution hydroxyl ions, leading to competition with P ions for sorption sites (Eze and Loganathan 1990), and to enhanced solubilisation of the amorphous aluminium phosphate (White and Taylor 1977).
As for the use of nitrites/nitrates, sulphites and sodium aluminium phosphate, Denmark asserted that the Directive failed to meet the health requirements to which the country attaches key importance in the provisions for food additive.
In recent years, the problem had been somewhat addressed by the introduction of a new breed of baking powder which utilizes the slower reaction characteristics of sodium aluminium phosphate. For the first time, users were able to enjoy the benefits of long 'bench' times for a made-up mix, without fear of losing a substantial proportion of the available carbon dioxide release intended for that all-important 'rise' in the oven.
However, there has been a great deal of adverse comment in the media (including television current affairs programmes) suggesting that sodium aluminium phosphate together with other aluminium-based ingredient chemicals, none of which have EEC 'E' number approval, could be linked to various medical complaints.
Microorganisms solubilize the insoluble forms of phosphates like tricalcium, iron, and aluminium phosphates into available forms.
Senegal has reserves of 100m tons of calcium phosphates, 70m tons of aluminium phosphates and 330m tons of iron ore.
