Insoluble citrus fiber for animal feed and dietary supplement applications
Upcycled insoluble citrus fiber processed through nitrate removal, drying, and particle size reduction for use in poultry feed formulations and dietary supplements. Includes chemical characterization, safety testing, and functional validation across animal models.
Overview
This solution transforms insoluble citrus residue into a value-added ingredient suitable for animal feed and dietary supplements. The material shares a lignocellulosic profile similar to oat and rice bran, positioning it as a functional fiber source. By applying minimal processing, the approach preserves the inherent properties of the residue while meeting safety and regulatory requirements. The research supports two parallel application tracks: a chicken feed formulation study and a dietary supplement evaluation, both backed by rigorous chemical and biological characterization.
Technical specifications
Processing workflow:
- Nitrate removal to meet regulatory standards for non-toxic effluent, potentially carried out in biological reactors
- Drying and particle size reduction to produce a usable ingredient form
- Chemical identity profiling, including lignocellulosic and proximate analyses
- Microbiological quality assessment and heavy metal screening
- Stability testing to confirm shelf-life and functional integrity
Validation studies:
- Chicken feeding trials to evaluate nutritional performance
- Rodent studies measuring intestinal transit to confirm prebiotic potential
- Zebrafish toxicity assays to verify functional safety
Technology readiness level
The technology is at an early-to-mid development stage. Initial processing steps and characterization are planned or underway, with future validation encompassing nitrate removal optimization, comprehensive material characterization, and biological testing across multiple animal models. A final report consolidating all findings will document readiness for potential scale-up and commercialization. Cooperation agreements and institutional partnerships are being established to support progression toward market entry.
About EMBRAPA
Embrapa is Brazil’s national agricultural research enterprise under the Ministry of Agriculture, combining basic and applied R&D with large-scale field operations across dozens of research centers and experimental farms nationwide. Industry engages through regional hubs that co-locate laboratories with test plots and demonstration farms, enabling joint trials, cultivar evaluation, and validation in production environments. Dedicated technology transfer units structure licensing, germplasm access, and sponsored research, while extension interfaces translate results to producers through training and digital advisory tools. Research is supported by Brazilian federal appropriations, complemented by competitive funding from national science and innovation agencies and international partners.
