What is Pure Bilberry Extract?

Pure Bilberry Extract is made with the fruit of Vaccinium myrtillus that has not been adulterated with any fillers or carriers, delivering a highly concentrated source of natural potency in its own pure and undiluted integrity of its active compounds. Due to its unique dark purple color, this extract contains high amounts of anthocyanins, a family of bioactive flavonoids with known antioxidant properties, as well as their role in promoting enhanced flow of blood and eyes. High-quality Nutraceuticals and functional products are just another endorsement, sold in a different formula from diluted or combined formulations, which retain an abundance of fruit-derived polyphenols. Since it is soluble in both water and alcohol, it can easily be incorporated into capsule, powder, or liquid-based products. Designed to meet high-quality requirements and meet manufacturers who give preference to traceability and purity, the extract is consistent with the modern trend towards clinically proven plant-derived products.

History

Bilberry (Vaccinium myrtillus) is a plant with a long European history as a medicine that has been picked in countries, including Scandinavia. According to historical records, people have used bilberries since the Middle Ages; people have eaten them not only for consumption but also for promoting digestive health and healthy circulation. Research on the bilberry buzzed thereafter in the 20th century with accounts of World War II pilots, who were said to have used bilberry jam and found better night vision-experiments progressed to micro-level investigation of its anthocyanin content. These substances have been tested with regard to their impact on capillary health and antioxidant function, leading to the creation of consistent extraction formulations. Bilberry Anthocyanins are still important in modern and traditional medicine because of their age-old health use, first and then evidenced by current scientific inquiry.

Process

1. Raw Material Selection and Cleaning

So as to keep up purity, nothing but the best bilberry fruits are purchased and heavily cleaned to remove all foreign matter and impurities. The extensive cleaning leaves room for maintaining the extraction environment in a clean manner and limiting the chances of contaminating the extract by bringing in contaminants.

2. Crushing and Pulping

With mechanical crushing of the berries, the parts of the cell walls are broken, which releases the juice and pulp. This makes the plant matrix more susceptible to the action of the solvent in the subsequent phase.

3. Solvent Extraction

The formulation of water and ethanol in equal proportions is used as a solvent for the efficient isolation of anthocyanins and polyphenols from the fruit material. Extraction is carried out under certain temperatures and time points to achieve maximum yield with protection of key bioactive compounds.

4. Filtration

When extraction is finished, filtration is conducted to remove solid plant parts from the liquid extract. This procedure ensures the fact that the extract is not cloudy and free from superfluous fibers, inscrutable elements.

5. Concentration

Filtered liquid is subject to vacuum concentration for reducing the solvent concentration and increasing the overall potency of the extract. It is of central importance in producing reliable anthocyanin concentrations in extracts, reliable and consistent.

6. Purification (Optional)

To increase the standardization of several extracts, purification procedures consisting of membrane filtration or resin adsorption enhance anthocyanin concentration and eliminate sugars or non-essential constituents.

7. Drying

Pretreatment of the concentrated Bilberry Fruit Extract by either spray drying or vacuum drying results in a stable and manageable powder. The drying process is optimized such that the specified particle size and needs for solubility in the final product are met.

8. Standardization and Quality Testing

The powder is standardized to a defined percent of anthocyanins, for example, 25%, and quarantine checked for purity, moisture, heavy metals, and microbial contaminants prior to packing.

9. Packaging

Moisture-resistant, food-grade containers with nitrogen or in a low oxygen atmosphere are used to package the extract, therefore keeping it safe from light, air, and humidity in storage and transit.
