Color sells. Consistency keeps it selling. For formulators, distributors and private-label brands, anthocyanin-rich berry ingredients are judged twice: first on the appearance of the powder, then on the analytical certificate behind it. Xi'an Longze Biotechnology Co., Ltd. has built its business around that second judgment since 2009. The company develops, produces and sells natural active ingredients, with a portfolio centered on anthocyanidins and a clear focus on export-ready quality documentation.
The product photography tells the story plainly. Whole black currants, blueberries and cranberries sit beside glass dishes of deep purple-black, magenta-red and dark maroon powders. The color is not decoration. It is the first signal of raw material quality, extraction discipline and batch control. Buyers who need that signal to repeat from container to container should look closely at the specification range and the paperwork behind each lot.
A focused portfolio for anthocyanin formulations
Organic Acai Berry Powder (Euterpe oleracea Mart.) is produced from the fruit and milled to 80 mesh. It is organic certified, food grade, free from artificial colors and flavorings, and selected for excellent water solubility. The powder presents as a purple-red fine powder and carries a 24-month shelf life when sealed in a cool, dry, dark place.
Bilberry Extract (Vaccinium myrtillus L.) is standardized from 1% to 25% anthocyanidins by UV and 1% to 36% anthocyanins by HPLC. The extract is positioned as a high-activity anthocyanin material for eye-care and anti-aging skincare concepts, with customizable content for buyers who need a tighter specification.
Blueberry Extract (Vaccinium corymbosum L.) offers a wider analytical menu: 1% to 25% anthocyanidins by UV, 1% to 40% anthocyanins by HPLC, 1% to 20% pterostilbene by HPLC and 1% to 50% proanthocyanidins by UV. This flexibility lets a formulator choose the marker that fits the finished product story rather than forcing the formula around a single standard.
Cranberry Extract (Vaccinium macrocarpon L.) is built around proanthocyanidins, with 1% to 25% anthocyanidins by UV, 1% to 60% PAC by UV and 1% to 25% PAC by DMAC/BL-DMAC, alongside quinic acid and total acid. The material is suited to products positioned around urinary tract care, antioxidant support and daily wellness.
Black Currant Extract (Ribes nigrum L.) carries 1% to 25% anthocyanidins by UV, 1% to 35% anthocyanins by HPLC, 1% to 40% polyphenols by UV and 1% to 60% proanthocyanidins by UV. The combination of anthocyanins and multipotent polyphenols gives product developers room to work across eye health, skin condition and metabolic wellness categories.
Black Elderberry Extract (Sambucus nigra L.) is standardized to 1% to 25% anthocyanidins by UV, 1% to 25% anthocyanins by HPLC and 1% to 30% polyphenols by UV. It is a natural fit for immune-support positioning, particularly in capsules, gummies, powders and functional beverages.
All six ingredients are milled to 80 mesh and carry a 24-month shelf life under sealed, cool, dry and light-protected storage. Specifications are customizable on request, which matters for buyers who need to match an existing label claim or develop a new formula.
Quality systems built for export markets
Longze selects raw materials with origin in mind: organic acai berries from the Amazon basin, wild high-altitude bilberry from Europe, North American cranberries, and black currant and elderberry from cold, high-altitude growing regions. Low-temperature extraction is used to retain natural active compounds, with batch content held to a stable range.
Pesticide residues, heavy metals and microbiological indicators are controlled against EU and US food export standards. Every batch can be supported with a COA quality inspection report and SGS third-party test data, with traceability through the production chain. The company operates two cGMP-compliant production plants and maintains an organic raw material planting base and processing base in Jilin Province, China. Independent R&D and QC centers support closed-loop quality control from incoming raw material to finished powder.
The factory holds certifications including ISO9001, ISO22000, FSSC22000, HACCP, HALAL, KOSHER and organic certification. SGS and Eurofins third-party reports are available to support compliant export to global markets. For buyers who need to verify a supplier before placing a first order, that documentation set is often the deciding factor.
Applications across five sectors
The range is used across food and beverage, dietary supplements, cosmetics and personal care, pharmaceuticals and animal nutrition. In beverages and powdered drinks, the water-soluble powders deliver color and anthocyanin content without artificial colors. In supplements, standardized extracts support capsules, tablets, sachets and gummies. In cosmetics, the same anthocyanin-rich materials fit serums, masks and antioxidant skincare concepts. Pharmaceutical and animal nutrition buyers use the extracts as functional raw materials with defined marker compounds.
Market demand continues to move toward clean-label color, recognizable fruit sources and transparent testing. Berry anthocyanins sit at the intersection of those trends. They give formulators a plant-based story, a measurable active marker and a visual identity that consumers associate with real fruit. The commercial opportunity is strongest when the ingredient specification, the finished product claim and the certificate of analysis all say the same thing.
Packaging, lead time and export support
Sample packaging is available in 10 g, 50 g and 100 g sterile independent packs. Commercial packaging uses 1 kg food-grade vacuum foil bags. Bulk orders ship in 25 kg thickened standard fiber drums. Custom logos, labels, outer packaging and specifications are available for private-label programs.
Orders are typically dispatched within 1 to 3 working days. International express, air freight and sea freight are supported, including FCL and LCL. Export documents including MSDS, COA and commodity inspection certificates are provided to keep customs clearance moving and delivery predictable.
OEM and ODM from specification to shelf
Longze offers one-stop OEM and ODM services for fruit and vegetable powders, anthocyanin content, compound formulas, color, particle size and solubility. Powder packaging, private labeling and formula customization are handled under one roof. Buyers can start with a sample, confirm the analytical target, then scale to commercial production without changing suppliers between the sample and the shipment.
Core cooperation terms include free product samples, full export documents, professional pre-sales consultation and after-sales technical support. Factory-direct supply removes intermediary cost and supports long-term stable supply for distributors and brand owners.
Start with a sample and a specification
If you are sourcing anthocyanin-rich berry ingredients for a new product launch, a private-label range or a distribution portfolio, the fastest next step is a sample and a specification conversation. Tell us the fruit, the marker compound, the target percentage, the application and the packaging format. We will match the specification and send the supporting documentation with the sample.
