Abstract
Abstract Vegetable protein containing foods, food products and/or feeds may be fortified with amino acids according to a process which includes tempering the foods, food products and/or feeds in an alkaline catalyst containing solution having a pH in the range from about 8.0-14 in the presence of the amino acids and at temperatures ranging from room temperature up to about 300*F. By this process, the food, food product and/or feed can be fortified with 0.05 - 25 percent of its weight of amino acids.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
88 words
A PROCDSS FOR FORTIFYING VEGETABLE PORTEIN FOOD PRODUCTS FOR HUMAN AND ANIMAL CONSUMPTION WITH AMINO ACIDS COMPRISING THE STEPS OF: A TEMPERING SAID PRODUCTS IN AN AQUEOUS SOLVENT HAVING A PH IN THE RANGE FROM ABOUT 8 TO 14 FOR A TIME SUFFICIENT TO ACHIEVE THE DESIRED AMINO ACID FORTIFICATION, SAID SOLVENT CONTAINING AN ALKALINE CATALYST AND FROM 0.05 TO 20 PERCENT BY WEIGHT OF SAID AMINO ACID BASED UPON TO WEIGHT OF THE UNTEMPERED PRODUCT, AND B. DRYING SAID TEMPERED PRODUCT TO REDUCE THE MOISTURE LEVEL THEREOF.
Claim 2
Dependent Claim
88 words
A PROCDSS FOR FORTIFYING VEGETABLE PORTEIN FOOD PRODUCTS FOR HUMAN AND ANIMAL CONSUMPTION WITH AMINO ACIDS COMPRISING THE STEPS OF: A TEMPERING SAID PRODUCTS IN AN AQUEOUS SOLVENT HAVING A PH IN THE RANGE FROM ABOUT 8 TO 14 FOR A TIME SUFFICIENT TO ACHIEVE THE DESIRED AMINO ACID FORTIFICATION, SAID SOLVENT CONTAINING AN ALKALINE CATALYST AND FROM 0.05 TO 20 PERCENT BY WEIGHT OF SAID AMINO ACID BASED UPON TO WEIGHT OF THE UNTEMPERED PRODUCT, AND B. DRYING SAID TEMPERED PRODUCT TO REDUCE THE MOISTURE LEVEL THEREOF.
