Bitter Orange Peel Extract Powder
Overview
Bitter Orange Peel Extract Powder is derived from the dried peels of bitter oranges (Citrus aurantium), a citrus species native to Southeast Asia. The extract is valued for its rich content of bioactive compounds, including flavonoids like naringin and hesperidin, which contribute to its antioxidant and aromatic properties. Traditionally used in herbal medicine, the powder has gained industrial significance due to its versatility in food, beverage, and cosmetic formulations. It is often preferred over synthetic alternatives for its natural origin and functional benefits.
Physical and Chemical Properties
The powder typically appears as a fine, yellowish-brown substance with a characteristic citrus aroma. Its solubility in water and ethanol makes it suitable for various liquid formulations. The extract’s density ranges between 0.4-0.6 g/cm³, and it is hygroscopic, requiring careful storage to prevent clumping. Key chemical constituents include flavonoids (up to 10-15%), volatile oils (limonene being the primary component), and polyphenols. These compounds contribute to its antioxidant, anti-inflammatory, and flavor-enhancing properties, making it a multifunctional ingredient.
Main Applications
In the food and beverage industry, the powder is used as a natural flavoring agent in teas, candies, and alcoholic beverages. Its bitter yet aromatic profile complements herbal blends and craft cocktails. The cosmetic industry incorporates it into perfumes, soaps, and skincare products for its fragrance and potential skin benefits. Dietary supplements leverage its bioactive flavonoids for promoting digestive health and antioxidant support. Its GRAS status by regulatory bodies like the FDA ensures widespread acceptance in these applications.
Safety and Storage
Bitter Orange Peel Extract Powder is generally safe for consumption and topical use, though excessive inhalation of the powder should be avoided to prevent respiratory irritation. It is non-toxic and non-irritating under normal usage conditions. Storage recommendations include keeping the powder in airtight containers in a cool (below 25°C), dry environment. Exposure to moisture or direct sunlight can degrade its active compounds, reducing efficacy. Shelf life typically ranges from 2-3 years when stored properly.
B2B Procurement Guide
When sourcing Bitter Orange Peel Extract Powder, prioritize suppliers with certifications such as ISO 9001 or GMP compliance to ensure quality and traceability. Request detailed specifications, including flavonoid content (e.g., naringin percentage) and solvent residues, if applicable. Pricing varies based on purity and volume, with bulk purchases (e.g., 100+ kg) often attracting discounts. Sample testing for microbial contamination and heavy metals is advisable. Reliable suppliers provide batch-specific COAs (Certificates of Analysis) and adhere to sustainable sourcing practices.
