Research Project:
CHARACTERIZATION, PROCESSING AND NOVEL, NON-FEED USES FOR PROTEINACEOUS RENDERING BYPRODUCTS
Location: Fats, Oils and Animal Coproducts Research
Project Number: 1935-41440-015-00
Project Type:
Appropriated
Start Date: Dec 08, 2004
End Date: Nov 30, 2009
Objective:
(1) Separate and characterize the components: Develop methods to
separate the soft tissue fraction from the bone fraction. Characterize
meat & bone meal (MBM), and its fractions, in terms of their composition
and physical properties.
(2) Modify the functionality: Establish the range of functional
properties achievable by subjecting MBM protein to varying degrees of
hydrolysis and subsequent crosslinking.
(3) Apply in fermentation media: Develop and evaluate an MBM
hydrolysate for use in industrial fermentation as a source of amino
acids and micronutrients.
Approach:
(1) Separate soft tissue material from bone material; determine the
proximate composition and physical properties of both fractions.
Combine amino acid and mathematical analyses to determine the identity
and concentration of each of the major proteins.
(2) Evaluate methods for the controlled hydrolysis of the protein in
whole or fractionated MBM. Emphasize methods purported to inactivate
BSE prions, but likely to scale up well and be economical. Evaluate the
crosslinking of some hydrolysates. Determine several of the bulk
functional properties of the treated protein and compare with those of
other commercial proteins.
(3) Develop an economical process for production of an MBM or component
hydrolysate that matches or exceeds the desirable characteristics of
other undefined nitrogen sources for low-cost, non-pharmaceutical
industrial fermentation.
