Innovation in the rendering industry

Jessica Meisinger, Ph.D.

Fats and Proteins Research Foundation

• Founded in 1962

• Direct and manage a research process that results in an enhanced current usage and the development of new uses for rendered animal products

– Nutrition, biosecurity, food safety, non-feed uses, biofuel

• Completed over 575 projects

FPRF Research Funding

• Robust research program

• Two funding streams

– At-large

– ACREC

At Large

• Currently funding over $300,000 worth of research

• Currently focused on animal nutrition

• RFPs due twice a year, in April and October

• Current projects…

Replacing Fish Oil

• Jesse Trushenski, SIU

• Determine the relative requirements of LC-PUFA

• Fish meal and fish oil sources are diminishing

– Few sources of EFA

• Using rendered animal fats that are rich in SFA

– Beef tallow

– Atlantic salmon, hybrid striped bass, pompano

Phosphorus and Amino Acid Digestibility

• Hans Stein, University of Illinois

• Measure the digestibility of phosphorus and amino acids in 8 sources of meat and bone meal

– Estimate variation among sources

– Create a prediction equation AA and P concentration in MBM

Adding Value to Rendered Products in Relation to Aquaculture

• Dominique Bureau, University of Guelph

• Fine characterization of the nutritional content of rendered proteins with emphasis on minor nutrients and minerals

• Evaluate processing techniques and food additives to improve digestibility of nutrients

• Develop and evaluate high digestible nutrient density “low pollution” ingredients for use with carnivorous fish such as salmon

• Develop and evaluate lower economical value high ash animal proteins for tropical/warm water species such as Nile tilapia or shrimp

• Modify and validate an existing phosphorus digestibility model developed for salmonid fish to other fish species

Pet Food

• Greg Aldrich, KSU • Evaluation of techniques used to extend shelf-life and

methods for analysis of rendered protein meals in pet foods” • Determine the efficacy of rapid methods like SafTest relative

to conventional methods for measures of oxidation in rendered protein meal

• Determine best practices for confirming preservative application and to determine the effects of rendered protein meal particle size on the efficacy of antioxidant dispersal, coverage, and oxidative stability

• Determine the effects of various carriers and preservative systems on the stability of rendered protein meals under various environmental and handling conditions

Pet Food

• Greg Aldrich, KSU • “The impact of rendered protein meal level of

oxidation on shelf life and acceptability in extruded pet foods”

• Determine the effect of incorporating increasing levels of oxidation in rendered protein meals on markers of oxidation in extruded pet food

• Determine the effect of increasing rancid ingredients on the shelf-life and acceptability of extruded pet foods

• Use regression analysis to determine the amount of oxidation (PV) that could be allowed in a rendered protein meal without negatively affecting the shelf-life and acceptability of the finished pet food

Pet Food

• Cassandra Jones

• Asses the efficacy of chemical additives to control Salmonella recontamination in rendered by-products

ACREC Mission Statement

• ACREC seeks to advance the science and technology of animal co-products and the rendering process

• In addition, the Center works to ensure microbial safety of rendered products for animal feeds and consumer protection, promotes environmentally sound practices, develops new market opportunities for the worldwide rendering industry and provides educational opportunities in animal co-product utilization

ACREC

• First 9 projects started in 2004

• Inter-disciplinary

• Large range of projects from many departments including animal science, microbiology, engineering, chemistry

Wastewater Treatment

• Scott Husson

• Developing a wastewater treatment membrane

– Environmentally friendly

– Cost effective

Antioxidant Production

• Vladimir Reukov and Alexey Vertegal

• Producing a novel antioxidant that is both natural, effective, and cost-effective

Odor Elimination

• Daniel Whitehead and Frank Alexis

• Using nanoparticles to target and eliminate odors

• Huge practical value

Feather Meal Safety

• Joseph Thrasher

• Re-conducting a study by Johns Hopkins that found contamination in feather meal

Salmonella Reduction Using Bacteriophages

• Xiuping Jiang

• Salmonella is a concern in the rendering industry

• Bacteriophages work on the lab scale, now testing in plant as a proof of concept

Validation of Rendering as a kill-step

• Annel Greene

• Validating that Salmonella and Clostridium perfringens are killed during rendering

Renderable gloves

• Andrew Hurley

Other Recent Research

• Carbon footprint

• Lifecycle analysis for GHG emissions

• Identifying cost-effective paths for new high value products from rendered fats

• Non-feed uses of rendered product

• Novel changes in operations

Separating fat from protein

• Chris Kitchens

• Use CO2 to more effectively separate fats and proteins

Conclusions

• Active research program

• Innovation!

• Currently focused on nutrition, plant operation, environmental factors
