Abstract
Abstract This invention relates to methods of producing protein material from soybean or other vegetable materials containing protein, which protein material is useful as food. This protein material is produced by freezing a protein-containing solution, keeping it frozen for a specific time, thawing it, and then separating the protein material thus formed by filtration or centrifugation. A special feature of the process of this invention is to add a divalent salt into a protein-containing solution prior to freezing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
69 words
A METHOD OF PRODUCING SOLID PROTEIN MATERIAL WITH A SPONGY TEXTURE, WHICH COMPRISING ADDING AN EDIBLE DIVALENT SALT TO A SOLUTION F SOYBEAN PROTEIN IN SUCH AN AMOUNT THAT THE SOLUTION BECOMES TURBID WHITE WITH PROTEIN, A PART OF SAID PROTEIN BEING STILL DISSOLVED, FREEZING THE SAID SOLUTION, KEEPING THE SOLUTION FROZEN FOR FROM ABOUT ONE TO TWO DAYS, AND THEN THAWING AND RECOVERING THE RESULTANT SOLID PROTEIN MATERIAL.
Claim 2
Independent Claim
69 words
A METHOD OF PRODUCING SOLID PROTEIN MATERIAL WITH A SPONGY TEXTURE, WHICH COMPRISING ADDING AN EDIBLE DIVALENT SALT TO A SOLUTION F SOYBEAN PROTEIN IN SUCH AN AMOUNT THAT THE SOLUTION BECOMES TURBID WHITE WITH PROTEIN, A PART OF SAID PROTEIN BEING STILL DISSOLVED, FREEZING THE SAID SOLUTION, KEEPING THE SOLUTION FROZEN FOR FROM ABOUT ONE TO TWO DAYS, AND THEN THAWING AND RECOVERING THE RESULTANT SOLID PROTEIN MATERIAL.
Claim 3
Dependent Claim
29 words
A method as claimed in claim 1, wherein the amount of edible divalent salt to be added is from 0.20 to 0.30 m mol per 1 g of protein.
