The present invention is directed to a calcium containing vegetable protein containing composition, comprising; a calcium containing protein material containing at least 90% protein by weight, dry basis, said protein material having a dry basis degree of hydrolysis of from about 1.8% up to about 4.0%, a dry basis calcium content of from 0.10% up to about 0.6%, a dry basis density of from about 0.28 up to about 0.48 g/cc, a pH of from about 6.9 up to about 7.7, and a particle size wherein not more than 10% of the particles are retained on a 30 mesh screen. The present invention is also directed to a calcium containing vegetable protein based beverage composition, comprising; a liquid and a calcium containing hydrolyzed soy protein isolate containing at least 90% protein by weight, dry basis, said protein material having a degree of hydrolysis of from about 1.8% up to about 4.0%, a percent calcium of from about 0.15 up to about 0.60, a density of from about 0.15 up to about 0.48 grams per cubic centimeter, a pH of from about 6.9 up to about 7.7, and a particle size wherein not more than 10% of the particles are retained on a 30 mesh screen
