Explore our elite portfolio of high-purity biological extracts, food-grade amino acids, and enzyme solutions designed for global manufacturing compliance.
The global demand for premium collagen extracts has undergone a structural shift. Modern food, beverage, nutraceutical, and cosmeceutical developers no longer view collagen merely as an emulsifying agent or simple protein source. In the contemporary regulatory and consumer landscapes, search intent revolves around specific efficacy markers, target molecular weight distributions (Daltons), bio-availability rates, and verifiable sustainability matrixes. Global enterprises are seeking reliable B2B manufacturers and exporters capable of delivering customized animal-derived (bovine, marine, porcine) and next-generation recombinant vegan peptides via robust OEM/ODM pipelines.
For international sourcing directors and formulation scientists, the supply chain for raw ingredients requires intense vetting. Low-grade collagen peptides often suffer from organoleptic defects (strong odor, off-taste), heavy metal contamination (arsenic, lead, mercury), and irregular molecular weight profiling. Our engineering team resolves these quality bottlenecks by operating under strict GMP controls, utilizing multi-stage membrane filtration, enzyme degradation modeling, and clean room spray drying techniques.
From molecular customization to advanced delivery forms, we support your product development roadmap.
We tailor the enzymatic hydrolysis process to target precise peptide fractions (e.g., 500 Da for topical cosmetics, 2000-3000 Da for nutraceutical beverages) ensuring superior solubility and absorption rates.
Integration of synergistic compounds. We combine collagen bases with functional additives like GABA, Bromelain, and Vitamin C to manufacture clinically backed nutritional solutions.
We offer turnkey manufacturing options including Bulk Powders, Single-serve Sachets, Liquid Ampoules, Solid Drink Mixes, and standard container fillings tailored to regional target markets.
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, the company is 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.
The company is located in Xi’an, Shaanxi Province, China. Our production base covers an area of over 70,000 square meters and is equipped with six advanced plant extraction production lines, fine extraction workshops, and modern processing facilities.
We operate under strict GMP-compliant manufacturing systems, ensuring that every stage—from raw material selection and extraction to final packaging—is carefully controlled and standardized. Our facilities are supported by a modern quality inspection and testing center, enabling comprehensive monitoring of product purity, stability, and safety.
Quality Assurance & Certifications: Shaanxi Diaries Biotech maintains a rigorous quality management system that meets international standards. Most of our products are certified under globally recognized systems, including: HACCP, ISO22000, ISO9001, USDA Organic, EU Organic, Kosher, Halal, and FDA compliance.
A core focus of our research development center is optimizing the organoleptic and physical properties of our ingredients. For collagen and plant proteins, this entails addressing issues with dust generation, bulk density, wetting index, and color profile. Through advanced processing controls, we deliver high-performance powders suitable for direct blending, compression, and liquid canning.
Additionally, the incorporation of specialized botanical materials (such as Ursolic Acid and Rosemary Extract) serves as a functional matrix, offering natural antioxidant properties that extend shelf-life and enhance product performance.

Technical clarifications on ordering, molecular profiles, OEM/ODM processes, and compliance.
Our raw material supply chain includes premium bovine skin/cartilage, marine fish skin/scales, and innovative plant-based / vegan proteins (such as our high-content food grade yeast protein extracts). Each raw input undergoes rigorous traceability validation before entering the extraction tank to ensure clean origin profiles.
Yes. Utilizing state-of-the-art enzymatic hydrolysis (using targeted food-grade enzymes like bromelain or papain), we can engineer average molecular weights ranging from very low-mass peptides (<1,000 Daltons for cosmetics and rapid-absorption nutrition) to 3,000 Daltons (suited for functional beverages, solid drinks, and protein powders).
We deploy high-precision multi-stage filtration loops, involving activated carbon powder treatment, microfiltration, and specialized membrane concentration modules. This process removes trace heavy metals, volatile fatty acids, and aromatic impurities, delivering neutral-tasting powders that dissolve into completely transparent solutions.
Our 70,000 square meter plant operates under GMP compliance. Our certification matrix includes ISO9001, ISO22000, HACCP, Halal, Kosher, USDA/EU Organic, and FDA registration. This guarantees smooth clearance during global import and export custom audits.
Absolutely. Our OEM/ODM support spans across customized premixes (e.g., blending sleep aids like GABA and casein peptides, or adding antioxidants like rosemary extract to enhance stability). We also guide formulation adjustments to optimize taste, solubility, and shelf-life before scaling up to commercial runs.
For standard raw materials, shipments are processed within 7 to 15 working days. For custom OEM formulations, packaging runs, or specialized private label projects, the average turnaround is 3 to 5 weeks, depending on materials sourcing, formulation approval, and laboratory validation schedules.
Maximize formulation efficacy by combining collagen with high-purity natural additives, preservatives, and nutritional enhancers.
