Modern consumers are moving beyond simple "regularity." Insoluble fiber is now recognized for its role in the gut-brain axis, blood sugar modulation, and as a critical structural component in plant-based meat analogs. OEM factories are seeing a 40% increase in demand for multi-functional fiber blends.
Traceability is paramount. Global procurement teams now prioritize "Farm-to-Factory" transparency. Insoluble fiber derived from upcycled agricultural side-streams (like fruit peels or grain husks) is gaining significant market share due to its low carbon footprint.
The "gritty" texture of traditional insoluble fiber is a thing of the past. Technical routes now involve ultra-fine milling and enzymatic modification to improve mouthfeel in beverages and dairy alternatives, allowing for higher fiber loading without compromising sensory profiles.
Benefiting from the solid foundation provided by its parent company, Xi'an Tianben Bioengineering Co., Ltd., Botanical Cube Inc. focuses on researching, developing, producing and selling healthy natural ingredients. With more than two decades of industry experience, it has become a leader in the field, specializing in providing high-quality plant extracts and customized solutions to global customers.
Our operations are supported by three companies - Xi'an Tianben Bioengineering Co., Ltd., Botanical Cube Inc. and Shaanxi Tianben Kangyuan Biotechnology Co., Ltd. - which together operate 3 production bases covering more than 100 acres and process more than 3,000 tons of plant raw materials each year.

We provide a comprehensive technical roadmap for insoluble fiber powder development:
Navigating international regulations is our specialty. Our factory provides full support for:
Our first factory was established in 2012 in Sanyuan City, Xi'an, four years after our company was founded. These early efforts laid a strong foundation for our future growth, shaping the high standards of excellence that we uphold today.
Powder collection, crushing and sieving, mixing and drying processes are all performed in a Class 100,000 cleanroom environment. Our operators strictly follow hygiene protocols and wear sterile gowns, masks and gloves to maintain product purity and safety, thus ensuring that we provide our customers with high quality standards and reliable ingredients.





Q: What is the primary difference between soluble and insoluble fiber for OEM applications?
A: Insoluble fiber does not dissolve in water and remains relatively intact as it moves through the digestive tract. In OEM formulations, it provides structural bulk, supports "satiety" claims, and improves bowel transit time, whereas soluble fiber is primarily used for its prebiotic and gel-forming properties.
Q: How does mesh size affect the quality of insoluble fiber powder?
A: Mesh size is critical for the "Information Gain" in product development. A coarser mesh (60-80) is ideal for baked goods to provide crunch, while a micronized mesh (200+) is essential for "smooth" fiber-enriched beverages where grit must be minimized.
Q: Can your factory handle "Clean Label" requirements?
A: Yes. Our Sanyuan factory uses purely physical extraction methods (milling, air-classification) without chemical solvents, meeting the strictest global definitions of "Clean Label" and "Natural."
Q: What are the storage requirements for bulk fiber powder?
A: Insoluble fiber is highly stable but hygroscopic. We recommend storage in a cool, dry place (<25°C, <60% RH) in sealed containers. Our packaging includes moisture-barrier liners to ensure a 2-year shelf life.
As we look toward 2030, the OEM insoluble fiber powder landscape is shifting toward "Precision Nutrition." Our R&D department is currently piloting Fermentation-Derived Fibers and AI-Optimized Particle Morphology to create the next generation of digestive health ingredients. These innovations will allow brands to claim higher fiber content with zero impact on flavor profiles.
By partnering with a factory that understands both the Macro-Industry Trends and the Micro-Technical Challenges, global brands can secure a competitive advantage through information gain and superior product performance.
