Method and process for acidic recycling of protein waste

Abstract

A method for recycling protein waste and producing an edible product for animal consumption comprises grinding animal carcasses or parts thereof and thereafter acidifying the waste. The acidified waste may then be emulsified, followed by a heat shock and then fed to animals. Alternatively, a second emulsification may be employed prior to being used for animal consumption. The emulsified products may be provided to animals as a liquid, or dried to a paste prior to use.

What I claim is: 
     
         1 . A process for making a product for animal consumption, said process comprising:
 a) Grinding a protein source with a carrier to generate a ground protein/carrier product;   b) Adding acid to the ground protein/carrier product at a temperature between about 90 degrees Fahrenheit and about 120 degrees Fahrenheit to generate an acidified ground protein/carrier product;   c) Mincing and maintaining the temperature of the acidified ground protein/carrier product between about 90 degrees Fahrenheit and about 120 degrees Fahrenheit at pH between about 2.5 and about 4.0 and allowing said ground protein to mostly liquefy to form an acidic digest medium exhibiting biological stability in a sealed container for at least 21 days.   
     
     
         2 . The process of  claim 1 , further comprising:
 mixing an amount of the acidic digest medium with an additional protein source to form an acidic mixture, followed by a heat shock, and emulsification.   
     
     
         3 . The process of  claim 2  further including a drying step after emulsification.
