Explore our highly integrated core products range—from advanced industrial machinery to functional botanical materials and micro-organism cultures.
The global wellness economy is undergoing a massive shift towards semantic health definitions. B2B buyers and product formulators no longer prioritize isolated chemical structures in isolation; instead, they seek the natural synergy of the Whole Plant Matrix. This entourage effect—where secondary metabolites, trace minerals, and natural fibers work in unison—delivers superior biological availability, physiological tolerance, and formulation stability.
As a premier Custom OEM Whole Plant Ingredients Manufacturer & Factory, Shaanxi Diaries Biotech Co., Ltd. addresses this paradigm by preserving the complete chemical fingerprint of the botanical source. Traditional isolation procedures often discard beneficial co-factors, which can lead to rapid oxidation or reduced consumer absorption. By utilizing comprehensive botanical profiles, we generate raw materials that offer real, documented "Information Gain" to functional food makers, cosmetic formulators, and pharmaceutical houses alike.
Shaanxi Diaries Biotech Co., Ltd. is a modern high-tech enterprise specializing in the research and development, production, and global distribution of plant extracts, natural raw materials, and functional ingredients for the health, food, and cosmetic industries.
With strong technical expertise and advanced manufacturing capabilities, we are committed to providing high-quality, safe, and effective natural solutions to customers worldwide. Our products are widely used in dietary supplements, functional foods and beverages, cosmetics, personal care products, animal nutrition, and agricultural applications.
Over the years, Shaanxi Diaries Biotech has built long-term partnerships with more than 5,000 companies across over 80 countries and regions, earning a strong reputation for reliability, consistency, and innovation in the natural ingredients industry.
Our primary portfolio covers high-purity plant extract powders, standardized herbal extracts, biological fruit and vegetable concentrates, organic dietary raw materials, and customized active compounds tailored to demanding customer specifications. We also offer specialized B2B OEM/ODM services, formulation engineering, and premium private label packaging options.
Our production base covers an area of over 70,000 square meters in Xi’an, Shaanxi Province, China. Equipped with six advanced plant extraction production lines and state-of-the-art testing complexes, we ensure full lifecycle control of our botanical extraction operations.
We continuously integrate next-generation manufacturing systems to achieve higher extraction efficacy while preserving bio-activity.
By employing pressurized hot water as an extraction solvent, we bypass the need for volatile organic compounds (VOCs). This preserves the structure of thermal-sensitive botanicals and aligns with clean-label, eco-friendly certifications globally.
Using target enzymes to breakdown plant cell walls increases raw ingredient yields and bioavailability. This increases functional content (like oligopeptides and SOD enzymes) without thermal damage.
Utilizing nanofiltration to concentrate active molecules at ambient temperatures, followed by low-temperature freeze-drying. This keeps delicate probiotic strains (like Bacillus Coagulans) highly active and stable.
Enclosing volatile plant molecules in protective maltodextrin and peptide matrices. This shields active components from gastric acid, improving final product performance and extending shelf-life.
How our strategically situated base in Xi’an ensures cost efficiency, batch consistency, and uninterrupted global B2B delivery.
Our primary factory is based in Xi’an, Shaanxi Province, China, adjacent to the Qinling Mountains. Known as the "Natural Herb Library" of China, this location provides direct, traceable access to hundreds of wild and cultivated plant species. Sourcing botanicals close to our facility minimizes long-distance shipping emissions, preserves raw plant freshness, and mitigates raw-material price volatility.
Additionally, the region’s established industrial infrastructure provides deep manufacturing benefits. The concentration of chemical engineers, agricultural experts, and advanced machinery manufacturers in Shaanxi allows Shaanxi Diaries Biotech to maintain high process optimization levels. Through automated packaging systems, high-efficiency boilers, and integrated material mixing, our throughput remains optimized even during periods of high global demand.
By linking localized agricultural co-ops directly to our GMP-certified extraction setups, we cut out intermediaries. This integrated approach allows us to deliver high-specification materials like fish collagen, Tremella extracts, and customized electrolytes with shorter lead times and robust analytical certification.
Optimizing whole plant formulations to meet distinct regional and industrial standards.
Global brand owners must satisfy complex regional food safety laws, including FSMA in the United States and Novel Food regulations in the European Union. Shaanxi Diaries Biotech Co., Ltd. addresses these regulatory requirements with transparent batch testing, complete raw material traceability, and third-party laboratory verification.
Our quality testing center monitors every run for key parameters, including active compound content (via HPLC/UV-Vis), heavy metal thresholds (via ICP-MS), residual pesticide levels, and microbiological counts. This ensures every shipment meets both national standards and our customers' specifications.
