Established in 2018, Shaanxi Bieyouth Biotech Co., Ltd. has grown into a leading global supplier of premium animal and plant extracts, advanced cosmetics raw materials, food additives, and active pharmaceutical ingredients (APIs). Our state-of-the-art manufacturing infrastructure features GMP-certified clean rooms and dual standardized production lines.
As a gold-standard producer, we specialize in high-activity bio-catalysts, notably Papain Enzyme. By leveraging green chemistry and modern extraction methods, we assist global enterprises in securing reliable, high-yield proteolytic enzymes that meet both budget targets and strict global safety requirements.
From our headquarters in China's botanical extraction hub, we export to partners in the United States, the United Kingdom, Canada, Russia, Australia, and beyond. We combine source-factory pricing with custom OEM/ODM packaging to deliver tailored, market-ready solutions.
Papain is a powerful sulfhydryl protease extracted from the green fruit of the papaya plant (Carica papaya). Known for its high thermal stability and activity across a wide pH range, it is an essential tool in modern biotechnology. Today's global industry is shifting toward high-purity, standardized bio-catalysts to replace synthetic chemical alternatives.
Industrial sectors like meat processing, craft brewing, digestive supplements, and gentle skincare are increasingly turning to natural enzymes. Plant-derived proteolytic enzymes like papain offer a cleaner, more sustainable alternative to synthetic chemical processing.
Regulatory bodies like the FDA, EFSA, and EMA demand strict control over heavy metals, microbiological loads, and solvent residues. Suppliers must offer reliable batch-to-batch consistency and complete trace documents (CoA, Allergen Statements, GMO declarations).
Agricultural fluctuations in papaya production can lead to price changes and raw material shortages. Strategic B2B buyers prioritize source factories with strong raw material networks, high-volume production limits, and stable pricing models.
Our pharmaceutical and food-grade Papain Enzyme is engineered to perform across diverse industrial environments. We customize enzyme activity levels (from 100,000 U/g to over 2,000,000 U/g) to match your specific production requirements.
Used as a natural meat tenderizer by breaking down tough collagen fibers. In beer brewing, it prevents chill haze by hydrolyzing haze-forming proteins during cold stabilization without affecting foam stability.
Acting as a gentle enzymatic exfoliator, papain selectively breaks down dead skin cells in the outer layers. This promotes smoother skin texture, minimizes dark spots, and helps keep skin clear and refreshed.
Incorporated into digestive enzyme formulations to support protein digestion and ease gastrointestinal discomfort. It remains highly active in both acidic and alkaline environments.
Added to livestock and aquaculture feeds to improve protein digestibility, increase nutrient absorption rates, lower feed conversion ratios, and support early growth phases.
Shaanxi Bieyouth Biotech Co., Ltd. provides customized manufacturing services that streamline the journey from raw materials to store-ready packaging.
Detailed consultation to define enzyme activity specs, physical form (powder/liquid), packaging design, and regulatory compliance targets.
Our lab formulates samples tailored to your target specifications, ensuring optimal solubility, stability, and enzyme performance.
Prototypes undergo evaluation, including activity essays and stability profiling. Production begins once you approve the samples.
Mass production runs in our certified GMP facility, utilizing strict quality controls and full batch tracking before final dispatch.
Our formulation team regularly customizes a variety of active materials, including:
Since our launch, Shaanxi Bieyouth Biotech has advanced raw material purity, expanded our research facilities, and established strong international trade relationships.
Participated in the Shanghai International Cosmetics, Personal Care and Home Care Raw Materials Exhibition, showcasing our latest active ingredients and custom enzyme formulations.
Obtained registration and certification from the US Food and Drug Administration (FDA) in August, strengthening our position as a trusted supplier for North American and European markets.
Expanded our global B2B operations and established a new biology research center. This facility is dedicated to studying cosmetic raw materials and plant-based active ingredients, and was recognized on the local government's key development list in 2022.
Awarded the honorary titles of "Integrity Enterprise" and "Quality Assured Enterprise" for our commitment to honest trade practices and rigorous quality control standards.
Our skilled technical, sales, and logistical specialists are dedicated to supporting your B2B purchasing needs, from initial formulation through final customs clearance.
