Whey products and a process for preparing a modified whey protein concentrate

摘要

The process for preparing a modified whey protein concentrate is disclosed, which comprises: (a) providing a whey protein solution having less than 5% total solids and a combined calcium and magnesium concentration of less than 70 mmol/kg on a dry basis and a pH of 6.0-7.5; (b) heat treating the solution obtained to greater than 70 Deg C for up to 60 minutes to denature the whey protein; (c) cooling the heated solution to 40-60 Deg C; and (d) spray drying to prepare a dried product. Also disclosed is a method for preparing a whey protein concentrate comprising: (a) providing a whey protein concentrate comprising of about 10-30% (w/w) total solids, a combined calcium and magnesium concentration of less than 70 mmol/kg, on a dry basis, and a pH of 6.5-7.5; (b) heating using a scraped surface heat exchanger (SSHE) to a temperature of greater than 70 Deg C for up to 60 minutes to denature the whey protein; (c) cooling the heated solution to 40-60 Deg C; and (d) spray drying to prepared a dried product.
