Overview
Flat Walnut Extract Powder is derived from the seeds of Juglans regia, commonly known as flat walnuts. This natural extract is prized for its high concentration of bioactive compounds, including polyphenols, flavonoids, and omega-3 fatty acids. It is widely used in the food, cosmetic, and pharmaceutical industries due to its nutritional and functional benefits. The extraction process typically involves solvent extraction or supercritical fluid extraction to obtain a concentrated powder form. The powder is known for its light brown color and fine texture, making it easy to incorporate into various formulations. Its versatility and health benefits have made it a popular ingredient in functional foods and dietary supplements.
Physical and Chemical Properties
Flat Walnut Extract Powder is characterized by its light brown appearance and fine particle size, which ensures good solubility in water and ethanol. The powder has a mild, nutty aroma and a slightly bitter taste, which is typical of walnut-derived products. Its density ranges from 0.5 to 0.7 g/cm³, making it a lightweight material. Chemically, the extract is rich in polyphenols and flavonoids, which contribute to its antioxidant properties. It also contains significant amounts of omega-3 fatty acids, which are beneficial for cardiovascular health. The solubility of the powder in both polar and non-polar solvents makes it suitable for a wide range of applications, from liquid formulations to solid dosage forms.
Main Applications
Flat Walnut Extract Powder is primarily used in the food industry as a natural additive to enhance the nutritional profile of products. It is commonly incorporated into energy bars, beverages, and baked goods to provide omega-3 fatty acids and antioxidants. The extract is also used in dietary supplements aimed at promoting heart health and reducing inflammation. In the cosmetics industry, the powder is valued for its skin-nourishing properties. It is often included in anti-aging creams, serums, and lotions due to its ability to combat oxidative stress and improve skin elasticity. Additionally, the pharmaceutical industry utilizes the extract in formulations designed to support cognitive function and overall wellness.
Safety and Storage
Flat Walnut Extract Powder is generally recognized as safe (GRAS) for consumption and topical use. However, individuals with nut allergies should exercise caution, as the extract may trigger allergic reactions. It is recommended to conduct a patch test before using the product in cosmetic formulations. Proper storage is essential to maintain the quality and efficacy of the powder. It should be kept in a cool, dry place away from direct sunlight and moisture. Sealed containers are preferable to prevent oxidation and contamination. The shelf life of the extract powder is typically 12-24 months when stored under optimal conditions.
B2B Procurement Guide
When procuring Flat Walnut Extract Powder, it is crucial to verify the supplier's credentials and the quality of the product. Look for suppliers who provide certificates of analysis (COA) to confirm the purity and composition of the extract. Organic certification is also important if the product is intended for use in organic formulations. Price negotiations should consider factors such as batch size, purity levels, and shipping costs. Bulk purchases often come with discounts, but it is advisable to request samples before committing to large orders. Additionally, ensure that the supplier has a reliable supply chain to avoid delays and inconsistencies in product quality.
