|1. (WO2018222620) METHODS FOR PRODUCING FEATHER-BASED FOOD PRODUCTS|
|Inventors:||YONEMOTO, Lucio Hiroshi
|Title:||METHODS FOR PRODUCING FEATHER-BASED FOOD PRODUCTS|
A method is provided for making food product ingredients from indigestible keratinous protein-containing material. The methods generally include adding an amount of cereal bran and/or one or more reducing sugars to the keratinous protein-containing material to provide a mixture and hydrolyzing the mixture. The methods generate fewer unpleasant odors, and food product ingredients produced by the method can similarly benefit. Antioxidants may also be added, and in such embodiments, even fewer off odors may be generated and/or palatability may be enhanced.
