Plant Extracts
➢ Product Name: Blueberry Extract
➢ Latin Name: Vaccinium myrtillus L. (Bilberry) / Vaccinium corymbosum L. (Cultivated Blueberry)
➢ Plant Part Used: Dried mature fruits of Ericaceae blueberry
Manufactured from dried mature blueberry fruits through sorting-impurity removal, low-temperature water-ethanol composite extraction, macroporous resin enrichment and purification, vacuum concentration and aseptic spray-drying. It mainly retains natural active components such as anthocyanins, proanthocyanidins and phenolic acids from blueberry fruits, without artificial monomer blending or extra exogenous auxiliary materials. It possesses physiological activities including free-radical scavenging, anti-oxidation and anti-inflammation, and is a commonly-used botanical raw material for food and dietary supplement industries. Compared with ordinary blueberry fruit powder, enriched extract delivers higher concentration of active ingredients with multi-component synergistic effects, suitable for product development of anti-oxidation maintenance, eye-related formulas and sub-health conditioning.
➢ Raw Material Source: 100% extracted from blueberry fruits, free of starch, dextrin and other exogenous additives.
➢ Processing Grade: Low-temperature first-grade refined extract. High-temperature-caused anthocyanin degradation is controlled; no artificial blending. Impurities, solvent residues, heavy metals and pesticide residues meet limit requirements for food-grade raw materials.
➢ Core Indicators: Total anthocyanins (HPLC) 5%-25%, total polyphenols 15%-40%; customized specifications are available upon demand.
➢ Physical and Chemical Properties: Water-soluble fine powder. Anthocyanins are sensitive to pH value, light and temperature. Encapsulated modified grades are available for improved stability to adapt to multiple dosage forms.
➢ Applicable Dosage Forms: Tablets, capsules, solid beverages, pressed candies, compound powders and others.
➢ Storage Properties: Sealed, light-proof and moisture-proof. Store in cool and dry place, avoid light exposure and high temperature to secure anthocyanin activity.
Select blueberry fruits from high-quality producing areas with proper maturity and high intrinsic anthocyanin content to guarantee raw-material quality and activity foundation from the source.
Adopt mild extraction and resin enrichment processes to maximally protect heat-sensitive active substances including anthocyanins and proanthocyanidins, preserve natural component ratio of fruits. The synergistic effect of natural compound system outperforms single anthocyanin monomer.
Free of blending, fillers, pigments, flavors, preservatives and harmful auxiliaries. Strictly control residues and microorganisms, complying with domestic health-food raw-material regulations and overseas pharmacopoeia standards.
Physicochemical properties are obviously affected by pH value, suitable for weakly-acidic systems. Can be used alone or compounded with other botanical extracts. Encapsulated modified products expand applicable formula scope for multi-category product development.
Produced in 100,000-class GMP workshop. Tested by HPLC and UV dual-methods. Key indicators of total anthocyanins and total polyphenols are strictly controlled for uniform batch quality and full traceability.
Uniform fine powder from purplish-red to puce with natural plant color, loose, delicate and good fluidity. It has characteristic blueberry fruity aroma, free of fermented, mildewed or scorched peculiar odor. Conventional grades are water-soluble; aqueous solution color changes significantly with pH value, showing purplish-red under acidic condition and turning blue-green under alkaline condition. Encapsulated modified products improve tolerance to light and pH, mask astringent taste, and show better overall quality than ordinary blueberry fruit powder.
Multi-component synergistic effect. Anthocyanin-proanthocyanidin centered polyphenol system presents prominent anti-oxidant capacity. Anthocyanins belong to light- and heat-sensitive substances; unmodified raw materials tend to degrade and deactivate under high temperature, light and alkaline conditions. Micro-capsule encapsulation greatly enhances processing tolerance, making up for the shortcoming of poor stability of ordinary anthocyanin raw materials.
Good formulation compatibility. Conventional water-soluble grades are mainly applied in solid beverages and instant foods; high-purity grades fit for tablets and capsules; encapsulated modified products improve processing resistance and reduce activity damage induced by pH and light, suitable for pressed candies. Strongly alkaline environments shall be avoided in formulas. Compatible with most industrial-production processes to satisfy mass-production and high-end customized development.
Food-grade high-barrier light-proof packaging isolates light, oxygen and moisture to slow down anthocyanin oxidative degradation and moisture caking. Store at cool room temperature without freezing. Use up promptly after opening. Flexible packaging specifications support lab-scale R&D, pilot test and large-scale production.
Blueberry anthocyanin complex, including cyanidin, delphinidin, peonidin and other anthocyanin glycosides, together with proanthocyanidins and phenolic acids. Synergy of multiple components forms the material basis for anti-oxidation and anti-inflammatory repair.
Anthocyanin molecules contain multiple phenolic hydroxyl groups, which can directly scavenge reactive-oxygen free radicals and inhibit lipid peroxidation. They boost activities of endogenous antioxidant enzymes such as SOD and glutathione to build dual anti-oxidant barriers, alleviate cell damage caused by oxidative stress and retard cellular oxidative aging.
Modulate NF-κB signaling pathway, down-regulate expression of pro-inflammatory factors including TNF-α and IL-6, inhibit chronic low-grade inflammatory response in vivo and mitigate inflammatory damage induced by oxidative stress.
Anthocyanins protect vascular endothelial cells, maintain microvessel integrity and permeability, improve microcirculation and reduce vascular endothelial damage caused by oxidation.
Anthocyanins scavenge free radicals in ocular tissues, relieve oxidative-stress damage to eye tissues and assist in maintaining normal physiological status of eyes.
Polyphenol components act on cell membranes, mitigate free-radical attack against membrane lipids, maintain cell-membrane structural integrity and reduce cell damage induced by external oxidative stimuli.
Raw material for anti-oxidation health foods, applied in capsules, tablets, solid beverages and other dosage forms, suitable for crowds with anti-oxidation demands and eye-care concerns.
Mainstream botanical raw material for domestic and overseas dietary supplements, featured with natural anti-oxidation and eye care. Developable into tablets, capsules and compound powders targeting consumers for daily sub-health maintenance.
Widely used in pressed candies, solid beverages, meal-replacement powders and instant functional foods. Often compounded with lutein, zeaxanthin and grape-seed extract to develop functional foods for eye care and anti-oxidation.
For scientific-research institutes and enterprise new-product development. Customized raw materials with different anthocyanin contents and micro-capsule encapsulation modification are available to support high-end compound-product development for anti-oxidation and eye care.
Meets quality requirements of USP, EP and FCC. Complete test documents are available for bulk export to global markets. It is one of the widely-used anthocyanin-based botanical raw materials worldwide.
Addable into pet nutritional powders and tablets for pet anti-oxidation, auxiliary oxidative-stress relief and maintenance of pet physical health.
