Houdek – Protéger: Fermented Plant-Based Pet Food Ingredient for Gut Health, Longevity and Sustainability

Houdek is an American manufacturer of sustainable, fermented ingredients for aquaculture, livestock, and pet food diets, headquartered in Volga, South Dakota. The company’s proprietary aerobic fermentation technology removes anti-nutritional factors from plant meals while amplifying nutritional benefits—increasing digestible protein, adding prebiotics and postbiotics, and incorporating beneficial isoflavones. Protéger is Houdek’s pet food ingredient brand, specifically formulated for manufacturers, branders, and distributors seeking highly digestible plant-based protein that supports gut health, promotes longevity, and delivers an exceptional sustainability story.

Houdek – Protéger at Interzoo 2026: Presenting Next-Generation Ingredients to Pet Food Professionals

Interzoo Nuremberg, the world’s leading trade fair for the pet industry, provides Houdek – Protéger with a strategic platform to connect with pet food manufacturers, brand owners, and ingredient distributors from around the world. Located in Hall 7, Booth 7-511b, as part of the country pavilions, Houdek will present its fermentation technology and Protéger ingredient line to professionals seeking science-backed, sustainable solutions for gut health-focused pet diets. The company’s GMP+, Non-GMO, SQF, and ProTerra certifications demonstrate its commitment to quality and responsible sourcing.

The Fermentation Difference: Removing Anti-Nutritional Factors, Amplifying Nutritional Benefits

Conventional plant-based ingredients often contain anti-nutritional factors that limit digestibility and nutrient availability. Houdek’s proprietary aerobic fermentation process—using a nutritive fungus—transforms traceable, responsibly grown plant meals into superior ingredients. The process:
• Removes anti-nutritional factors found in standard plant meals
• Increases digestible protein content
• Adds prebiotics (food for beneficial gut bacteria) and postbiotics (antioxidant and immune-health benefits from bacterial processing)
• Incorporates isoflavones, particularly aglycone form, which may support gut health, metabolic energy, and healthy body composition
• Improves palatability, even for cats
There is no effective comparison between Houdek’s fermented ingredients and traditional meals, concentrates, or isolates.

Protéger: A Multifunctional Pet Food Ingredient for Specialized Diets

Protéger is a plant-based, multifunctional ingredient specifically designed for pet food diets. Key attributes include:
• Plant-based protein with nearly zero anti-nutritional factors
• Important amino acid profile
• Highly digestible for optimal nutrient absorption
• Excellent palatability (verified even with cats)
• Isoflavones (especially aglycone form) for potential health benefits
• Prebiotics for gut microbiome support
• Postbiotics for antioxidant and immune-health benefits
• May improve coat health
• Outstanding sustainability credentials
For pet food manufacturers, Protéger offers a solution to three critical industry demands: gut health formulation, clean-label ingredient sourcing, and verifiable sustainability claims.

Proven Track Record: From Lab Scale to Commercial Manufacturing

Houdek’s fermentation technology has been developed and validated over more than a decade:
• 2012: Lab-scale testing of fermentation process
• 2015: First product (ME-PRO® for aquaculture) at pilot scale
• 2019: Commercial-scale manufacturing plant opens in Volga, South Dakota
• 2021: GMP+ and Non-GMO certification
• 2022: SQF (Safe Quality Food) and ProTerra certification
• 2023: Protéger for pet food diets launched
• 2025: Full suite of ingredients for livestock and pet food diets available
This progression from research to commercial-scale production demonstrates technical capability, quality control systems, and the ability to supply international partners reliably.

Sustainability: Deeply Rooted at Houdek

Houdek’s commitment to sustainability extends beyond typical plant-based claims. The fermentation process is extraordinarily input-efficient from farm to delivered product. Houdek knows its farmers and initial processors, having designed its process to isolate and improve every benefit from plant meals. The company provides a Sustainability audit and Life Cycle Analysis (LCA) on request. Key sustainability achievements include:
• Fermentation multiplies nutritional, environmental, and commercial value of plant meals
• Traceable, responsibly grown ingredient sourcing
• GMP+ certification for feed safety management
• ProTerra certification for social responsibility and environmental sustainability
• Non-GMO options available
For European pet food companies, where sustainability claims face increasing regulatory scrutiny, Houdek’s documented credentials reduce compliance risk.

Beyond Pet Food: Houdek’s Ingredient Portfolio

Houdek serves multiple sectors with its fermentation technology:
• Aquaculture (ME-PRO®): High-protein ingredient successful in 100% inclusion in fish and shrimp diets; improves water quality; high digestibility; easily extrudable with long shelf life
• Livestock (ACCESS Starter Protein™): Available in GM and non-GM varieties; supports swine, poultry, and cattle feeds; price stability; bonus oil with low free fatty acids and high Vitamin E
• Pet Food (Protéger): As detailed above, for gut health-focused formulations
This multi-sector footprint demonstrates manufacturing scale, technical expertise, and supply chain reliability—critical factors for international B2B ingredient partnerships.
