Pioneering clean-label functional bases and high-purity extraction materials for food, beverage, and life sciences.
The global food, beverage, nutraceutical, and cosmetic industries are undergoing a massive transition driven by the Clean Label Movement. As synthetic petroleum-derived dyes face increasing regulatory scrutiny (such as restrictions on azo dyes in the European Union and the state-level bans on artificial colors in the United States), consumer behavior has shifted irreversibly toward natural, plant-derived alternatives. However, shifting from synthetic molecules (like FD&C Red 40 or Yellow 5) to natural botanical complexes presents significant processing, stability, and formulation challenges.
At Shaanxi Diaries Biotech Co., Ltd., based in the botanical powerhouse province of Shaanxi, China, we operate as a premium Custom OEM/ODM manufacturer specializing in high-performance plant-based color solutions and functional active botanical extracts. We help global brands bridge the gap between regulatory clean-label compliance and physical product excellence by delivering tailored, heat-stable, pH-resilient, and oxidation-resistant natural color solutions.
According to industry intelligence, the global plant-based colors market is projected to grow at a compound annual growth rate (CAGR) of over 7.8% through 2032. The primary catalyst is the shift in global health policies and consumers’ desire for products that offer "Information Gain"—where ingredients not only serve a technological purpose (coloring) but also provide secondary biological benefits, such as antioxidant properties.
"True innovation in modern food science lies in turning a technological challenge—like stabilizing a sensitive red anthocyanin or a yellow carotenoid—into a nutritional advantage. When plant-based colorants preserve their inherent polyphenolic or antioxidant properties, they transform simple aesthetics into functional health benefits."
For global procurement directors, this transition demands more than just sourcing bulk powders. It requires navigating complex chemical matrices:
Leveraging smart infrastructure, automated extraction loops, and geographic resource access to guarantee reliable supply chains.
Our facility utilizes dual and multi-effect falling film evaporation machinery to process concentration steps at lower temperatures, preserving the integrity of biological pigment compounds.
Operating under comprehensive ISO22000, ISO9001, HACCP, USDA Organic, and Halal systems, each batch undergoes strict HPLC verification for standardization and safety.
We customize powder sizes, solubility factors (water or oil dispersibility), carrier choices (maltodextrin, gum arabic), and active concentration percentages to fit precise product pipelines.
Our production base in Xi’an, Shaanxi Province, China covers over 70,000 square meters and is equipped with six advanced plant extraction production lines, fine extraction workshops, and modern processing facilities. The company operates 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.

| Pigment Class | Botanical Source | Primary Hue | pH Stability Range | Thermal Limits | Recommended Applications |
|---|---|---|---|---|---|
| Anthocyanins | Sweet Potato, Sorghum Red, Elderberry | Red to Deep Purple | pH 2.0 - 4.5 | Up to 85°C (HTST) | Beverages, Yogurts, Fruit Preparations |
| Carotenoids | Carrot, Marigold, Tomato | Yellow, Orange, Pink-Red | pH 3.0 - 8.0 | Up to 120°C | Plant-based Meats, Confectionery, Margarine |
| Chlorophyllins | Alfalfa, Spinach, Nettle | Bright Green | pH 6.0 - 9.0 | Up to 100°C | Functional Beverages, Cosmetics, Hard Candies |
| Betalains | Red Beetroot | Magenta-Red | pH 3.5 - 7.0 | Below 75°C (Low Heat) | Ice Cream, Powders, Chilled Prepared Foods |
For food and cosmetics formulators, plant-based colors must perform predictably across various processing conditions. In acidic, dairy-based applications like yogurts, plant extracts must retain their aesthetic appeal without curdling proteins or shifting in hue. Our food-grade concentrates, such as natural yogurt flavor complexes and sorghum red extracts, are standardized to prevent off-flavor development and color degradation.
In active health supplements, consumers expect both functional active ingredients (like PQQ, Vitamin D3/K2, or Fisetin) and clean-label aesthetics. Standardizing botanical materials for capsules, softgels, and powdered blends requires reliable raw material suppliers who can ensure purity, prevent heavy-metal contamination, and maintain uniform bulk density.
Shaanxi Diaries Biotech Co., Ltd. operates under strict quality management systems that meet global standards. We provide batch-specific documentation, including Certificate of Analysis (CoA), pesticide residue profiles, allergen statements, and non-GMO declarations. Most of our products are certified under globally recognized quality systems, including:
With strong quality control procedures and continuous improvement practices, we are dedicated to delivering consistent, traceable, and premium-grade ingredients to our global partners. By combining advanced biotechnology with natural resources, Shaanxi Diaries Biotech Co., Ltd. strives to become a trusted global supplier of plant-based ingredients and a long-term partner in the health and wellness industry.
Technical insight on procurement, solubility, stability, and formulation of plant-based colorants.
Thermal stability is managed through advanced formulation adjustments. We utilize natural plant-derived carriers like gum arabic and customized maltodextrin to microencapsulate sensitive molecules (such as anthocyanins and betalains). This protects them from rapid thermal breakdown during processing steps like pasteurization or UHT treatment.
Yes, plant-based alternatives can replace synthetics, though color matching requires scientific profiling. For example, our food-grade sorghum red and purple sweet potato extracts can replace Red 40 in specific pH environments, while marigold and beta-carotene can replicate Yellow 5 and 6. Our laboratory team works closely with clients to match their color profile targets.
Under standard storage conditions (cool, dry environment, protected from light), our powder-form plant extract materials have a shelf life of 24 months. Liquid concentrates typically have a shelf life of 12 months when refrigerated.
Yes. Our processing lines are designed to handle 100% plant-based inputs. We maintain Kosher and Halal compliance certificates for our primary plant extracts and functional powder lines, allowing global buyers to meet diverse cultural and dietary requirements.
Standard OEM/ODM orders for custom botanical colorants begin at 100kg to 500kg, depending on the botanical raw material and processing requirements. For standardized catalog items, lower minimums may apply. Please contact our procurement team for specific details.
Natural agricultural raw materials naturally vary based on soil, weather, and harvest timing. We address this variation by blending raw extract batches to standard color value parameters, measured using UV-Vis spectrophotometers and HPLC analysis, ensuring consistent color values and tinting strength.
Highly concentrated pigments can carry trace flavors from their plant sources. We utilize deodorization processes and membrane filtration technologies to remove undesirable flavor compounds while concentrating the pigments, minimizing impact on the final product's flavor profile.
We operate a complete traceability program from raw material sourcing to packaging. We document every step from seed selection and harvesting to extraction and shipping, verifying organic integrity through USDA and EU organic certification audits.
