Premium-grade raw materials and natural processing formulations for global industries.
Analyzing the regulatory and chemical changes driving the global botanical colorings sector.
The global food, beverage, and cosmetic sectors are undergoing an unprecedented transition. Regulatory bans on synthetic colorants—such as Titanium Dioxide (E171) in the European Union and increasing scrutiny on artificial azo dyes (e.g., Red 40, Yellow 5) by health authorities worldwide—have accelerated the demand for natural alternatives.
Modern consumer behavior, heavily influenced by "clean-label" transparency, demands products colored solely with natural, plant-based materials. This paradigm shift requires industrial processors to replace stable synthetics with sensitive natural molecules like anthocyanins, carotenoids, and chlorophylls without compromising product shelf-life, visual vibrancy, or flavor profiles.
A premier high-tech enterprise specializing in the R&D, production, and global export of botanical extracts.
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.
Our core product offerings include: Plant extract powders, standardized herbal extracts, fruit and vegetable powders, botanical raw materials, and customized functional ingredient solutions. We also provide professional OEM/ODM services, formulation support, and private label manufacturing.
How we engineer nature's pigment molecules to survive demanding industrial processes.
Using low-temperature solvent-free methods to extract pigment molecules without causing thermal degradation, preserving the biological structure of anthocyanins, carotenoids, and chlorophyllins.
Coating pigment particles with food-grade carrier matrices (such as modified starches, gum arabic, or maltodextrin). This shields active color molecules from acidic beverage environments and thermal pasteurization.
Incorporate plant-derived polyphenols and ascorbic acid isomers to scavenge free radicals, improving UV resistance and shelf-life stability in retail product packaging.
A look inside our 70,000 square meter GMP-compliant facility in Xi'an, China.
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.
Providing optimized formulations across target food, beverage, and personal care categories.
RTD beverages require water-soluble natural colors that resist sediment formation and acid fade. For functional juices and energy drinks, we recommend microencapsulated carotenoids and acid-stable anthocyanins that remain vibrant at pH levels down to 2.8.
Extrusions and baking processes expose formulations to heat up to 180°C. Our heat-stabilized natural shades resist browning and color shift under thermal stress, providing bright hues for gummies, frostings, and snack foods.
In personal care, natural pigments must meet stringent microbiological requirements and remain skin-friendly. Our oil-dispersible botanical extracts provide clean and safe coloring options for lipsticks, balms, and emulsions.
Supporting global distribution with clean traceability, safety testing, and third-party 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:
Our in-house analytical lab validates batch consistency using advanced instrumentation:
Pioneering clean-label ingredients and extraction technologies for global industries.
By modeling the degradation pathways of specific botanical dyes under varied heat, light, and pH environments, our database helps us formulate protective barrier matrices tailored to individual beverage and food applications.
In addition to direct agricultural extraction, we are exploring precision fermentation using non-GMO microorganisms to produce red, blue, and yellow food-grade pigments, helping reduce water usage and carbon footprints.
Answering technical, regulatory, and application questions for procurement officers and R&D managers.
We resolve heat-sensitivity by using microencapsulation with food-grade carrier matrices (such as gum arabic or customized maltodextrins) and incorporating organic polyphenolic antioxidants. This method allows pigments to survive pasteurization processes up to 120°C–140°C without visible color loss.
Every batch of botanical material undergoes Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to detect heavy metals like Lead, Arsenic, Cadmium, and Mercury down to parts-per-billion (ppb) levels. Pesticide residues are screened using GC-MS and LC-MS/MS, conforming to strict EU and US FDA safety limits.
Yes. Through our custom OEM/ODM services, customers can send target samples. We use spectrophotometer analyses (CIE L*a*b* color space values) to match your requested hue, stability requirements, and solubility profiles using only clean-label plant extracts.
Our facility is located in Shaanxi Province, China, near rich botanical farming areas. We maintain contracted growing bases for key agricultural inputs, establishing vertical raw material control. Combined with automated extraction lines and standardized processing procedures, we minimize seasonal batch variations.
Yes. Our plant-derived colorants are completely vegan and non-GMO. We do not use chemical solvents or carriers derived from common allergens like gluten, soy, dairy, or nuts during our manufacturing process, assisting clients with clean, allergen-free product labeling.
