In the pharmaceutical chemical factories, bilberry extract's transformation process from raw materials to finished products contains fine technology and diverse application potential. From the blueberry fruit rich in active ingredients to the extract with specific medicinal value, every step has been scientifically designed and strictly controlled.
The preparation of bilberry extract takes ripe blueberry fruit as the starting material. In the chemical factories' preparation process, firstly, the fruit needs to be pretreated, and then the impurities are removed and crushed to increase the dissolution area of effective components. Commonly used extraction methods include solvent extraction and supercritical fluid extraction. In the solvent extraction method, ethanol has become the preferred solvent because of its high safety and strong solubility in anthocyanins. By controlling temperature, time, and material-liquid ratio, the effective components can be fully extracted. Supercritical fluid extraction (SFE) is a green and efficient extraction method, which takes carbon dioxide as the medium and is carried out at low temperature and high pressure. It can retain the activity of heat-sensitive components to the greatest extent and has no solvent residue, but the equipment cost is high.
The crude chemical factory's product contains a lot of impurities and needs to be purified. Macroporous adsorption resin is a commonly used purification material. Its porous structure can selectively adsorb target components such as anthocyanins, and impurities can be separated by a suitable eluent, thus improving the purity of the extract. Membrane separation technology has also been gradually applied to the purification of bilberry extract. Macromolecular impurities are intercepted by filter membranes with different pore sizes to realize the separation and concentration of effective components. After concentration, drying, and other steps, the powdery bilberry extract finished product is finally obtained, and the anthocyanin content in the finished product is usually strictly detected as a key quality index.
In chemical factories and pharmaceutical applications, bilberry extract has attracted much attention because of its rich antioxidant components. Its capsules, tablets, and other preparations are widely used in the field of ophthalmology health care, which can help improve retinal microcirculation and relieve asthenopia. In the research and development of cardiovascular drugs, bilberry extract's antioxidant and anti-inflammatory properties can be used to develop drugs to reduce vascular oxidative stress and prevent atherosclerosis; In addition, it also has broad prospects in the field of health care products, and can be added to oral liquid, soft candy and other products to meet consumers' demand for natural antioxidants.
With the continuous optimization of the extraction process and the in-depth study of its active components, the application boundary of bilberry extract in pharmaceutical chemical factories will continue to expand.
