Process for production of concentrates of chelated minerals with soybean amino acids and/or soybean protein, and related product

A process for obtaining a concentrate of chelated minerals, wherein said process comprises:

• (a) providing a reactor with a raw material containing amino acids or peptides from soybean aminogram diluted in water, in a proportion varying from 1 kilogram of soybean bran to 4 liters of the water up to 1 kilogram of the soybean bran to 7 liters of the water, with temperature between 3° and 50° C. under stirring to obtain a completely homogenized reaction mixture;
• (b) microparticulating the homogenized reaction mixture (2,500-5,000 rotations per minute) for a period ranging from 15 minutes to 2 hours, to form an emulsion;
• (c) reacting amino acids in the emulsion with metal in an aqueous solution of an alkalizing agent, adding transition metal salt or alkaline earth salt from 1.0:1.2-1.8 of divalent metal ions in relation to the amino acids, respectively, reaction occurring in an alkaline medium by addition of base or alkalizing agent in a molar concentration from 0.001 to 0.20 mole/liter of NaOH to form a reaction mixture;
• (d) dosing amylase and cellulase enzymes to the reaction mixture, which are allowed to react for 2 to 4 hours at a temperature of 40 to 60° C. and pH=4.5 to 6.5;
• (e) adding proteases to mixture obtained in the step (d), which react at pH=7.8 to 9.4 at a temperature between 5° and 70° C. for another 2 to 4 hours, until observation of reaction by analysis of degree of hydrolysis;
• and
• (f) subjecting product obtained to drying.
