The present invention relates generally to a method of producing plant proteins for use in nutritional products that have reduced levels of phytoestrogens, manganese or nucleotides. More specifically, this invention is directed to a method of using ion exchange technology to remove phytoestrogens, manganese or nucleotides from plant proteins. This invention is also directed to the plant protein product resulting from the inventive process and to nutritional products that use the plant protein product as a source of amino nitrogen.

Plant protein for nutritional products and method of making same

The present invention relates generally to a method of isolating phytoestrogens isoflavones from plant material. More specifically, this invention is directed to a method of using ion exchange technology to isolate phytoestrogens from plant protein isolates and to the phytoestrogen so isolated.

Process for isolating phytoestrogens from plant protein

A novel process for the removal of phosphorous from mammalian milk, preferably bovine skim milk, has been developed. The process involves passage of the milk at an elevated temperature through a Type I or Type II macroporous or gel type strong base ion exchange material in the chloride or carbonate form. The weak base anion sites inherent to the ion exchange material have been neutralized. The ion exchange material can easily be regenerated.

Removal of phosphorous from mammalian milk using ion exchange

A novel process for the removal of phytate from protein using ion exchange has been developed. The process involves the upflow passage of a protein slurry at an elevated temperature through a strong base anion exchanger in the chloride form. The weak base anion sites inherent to the resin have been converted to the free base form. The anion exchange material can easily be regenerated. The process can be used on-line, yields phytate removal of greater than 90%, has high (greater than 90%) protein recovery, is cost-effective, and is environmentally friendly.
