A process for producing whey derived products suitable for use in infant food formulas from edible cheese whey. The cheese whey is subjected to ultrafiltration to produce a protein-rich retentate and a lactose-rich permeate. The permeate is then partially demineralized as by electrodialysis, and blended with the protein-rich retentate. Also products produced by the process.

Modified whey product and process including ultrafiltration and

Superior soy protein beverages are prepared by formulation of carbohydrate, fat, or other nutritional ingredients with the liquid retentate of a soy protein ultrafiltration purification process without first recovering the soy protein by precipitation or drying of the retentate. Short-time high-temperature heat treatment of soy protein solution purified by ultrafiltration improves functional and nutritional qualities thereof.

Liquid dietary product containing soy protein membrane isolate

Soy protein isolate having a greatly reduced content of phytic acid and phytate complexes and high nutritional quality is prepared by aqueous extraction of defatted soy flakes at a pH in excess of the isoelectric value of the protein, basification of the extract to a pH in excess of pH 10.5, and removal of insolubles. The soy protein is then precipitated from the clarified extract by acidification within the isoelectric range.

Low phytate isoelectric precipitated soy protein isolate

A process is described by means of which whole soybeans are converted into a milk-like product which is bland in flavor, has functionality characteristics similar to cow's milk, and which has a substantially reduced proportion of soybean carbohydrate. The process involves a combination of blanching, wet grinding, homogenizing, centrifuging, and heat treating steps.

Soy lipid-protein concentrate

Soy protein having greatly reduced phytic acid and phytate complexes is prepared by aqueous extraction of defatted soy flakes, basification to a pH in excess of 10.1, and removal of insolubles. The clarified extract may be reduced in mineral and carbohydrates content by ultrafiltration. The purified aqueous extract may be advantageously used directly in the preparation of liquid dietary products without drying.
