Overview
Red Guava Extract is derived from the pulp or whole fruit of Psidium guajava, a tropical plant prized for its nutritional and therapeutic properties. The extract is concentrated through methods like water or ethanol extraction, preserving its bioactive compounds such as flavonoids, tannins, and ascorbic acid. It is increasingly popular in nutraceuticals and cosmetics due to its natural origin and multifunctional benefits. Unlike synthetic additives, red guava extract offers a clean-label solution for manufacturers seeking antioxidant or skin-enhancing ingredients. Its vibrant red color, derived from natural pigments like lycopene, also makes it a preferred choice for coloring applications in food and beverages.
Physical and Chemical Properties
Red Guava Extract typically exhibits a pH range of 3.5-5.0 in solution, reflecting its acidic nature from vitamin C and organic acids. The powder form has a fine, homogeneous texture with a characteristic fruity aroma, while liquid concentrates may vary in viscosity based on concentration. Key bioactive components include quercetin (a flavonoid with anti-inflammatory effects) and ellagic acid (a polyphenol with demonstrated anticancer properties). The extract’s antioxidant capacity is often measured via ORAC (Oxygen Radical Absorbance Capacity) values, which can exceed 30,000 µmol TE/g for high-quality extracts.
Main Applications
In the food industry, red guava extract is used to fortify juices, yogurts, and energy bars, leveraging its vitamin C content and natural sweetness. It also serves as a preservative due to its antimicrobial properties against pathogens like E. coli. The cosmetic industry values the extract for its ability to inhibit melanin production, making it a key ingredient in brightening serums and anti-aging creams. Studies suggest topical application can reduce UV-induced skin damage by up to 40% when formulated at 1-5% concentration.
Safety and Storage
Red Guava Extract is non-toxic and generally safe for consumption or topical use. However, industrial users should conduct patch tests for cosmetic formulations to rule out rare allergic reactions. Prolonged exposure to high humidity may cause clumping in powder forms, reducing shelf life. For bulk storage, airtight containers with desiccants are recommended. Liquid extracts should avoid freezing to prevent precipitation. Shelf life typically ranges from 18-24 months when stored properly, though potency of active compounds may degrade over time.
B2B Procurement Guide
When sourcing red guava extract, prioritize suppliers who provide transparent documentation, including Certificates of Analysis (COA) for active compound levels (e.g., polyphenol content ≥15%) and heavy metal testing. Organic certification (e.g., USDA, EU) ensures compliance with pesticide-free standards. For cost efficiency, consider blended formulations (e.g., combined with acerola extract) to achieve synergistic effects. MOQs (Minimum Order Quantities) for bulk purchases typically start at 25 kg, with price breaks at 100 kg. Sample testing for solubility and stability in your specific application is strongly advised.
