Overview
Hesperidin is a bioflavonoid predominantly found in citrus fruits, particularly in the peels of oranges and lemons. It is classified as a flavanone glycoside, composed of the aglycone hesperetin and the disaccharide rutinose. Hesperidin is widely recognized for its potential health benefits, including antioxidant, anti-inflammatory, and cardiovascular protective effects. In industrial contexts, hesperidin is extracted from citrus byproducts, making it a sustainable ingredient for pharmaceuticals and nutraceuticals. Its role in enhancing capillary strength and reducing inflammation has led to its inclusion in dietary supplements and functional foods.
Physical and Chemical Properties
Hesperidin appears as a pale yellow to white crystalline powder with a slight bitter taste. It is thermally stable but decomposes at temperatures above 250°C. The compound is sparingly soluble in water but dissolves well in organic solvents like DMSO and ethanol. Its molecular structure includes multiple hydroxyl groups, contributing to its antioxidant activity. Hesperidin’s solubility and stability profiles are critical for formulation in pharmaceuticals and food products, often requiring encapsulation or derivatization to improve bioavailability.
Main Applications
Hesperidin is primarily used in the pharmaceutical industry for its vasoprotective and anti-inflammatory properties. It is a key ingredient in supplements targeting venous insufficiency, hemorrhoids, and chronic venous disease. Additionally, hesperidin is incorporated into skincare products for its antioxidant effects. In the food industry, hesperidin serves as a natural additive to enhance the nutritional profile of beverages and functional foods. Its ability to scavenge free radicals makes it valuable in preserving product quality and extending shelf life.
Safety and Storage
Hesperidin is generally considered safe for consumption, with no significant toxicity reported at typical dosages. However, prolonged exposure to dust during handling may cause respiratory irritation. Proper personal protective equipment (PPE) such as gloves and masks is recommended. Storage conditions are crucial to maintain hesperidin’s stability. It should be kept in airtight containers, protected from light and moisture, at temperatures below 25°C. Bulk quantities require climate-controlled environments to prevent degradation.
B2B Procurement Guide
When procuring hesperidin, prioritize suppliers with certifications such as ISO, GMP, or USP to ensure quality and traceability. Key specifications include purity (typically 90-98%), heavy metal content, and microbiological limits. Pricing varies based on purity and market demand, with bulk purchases often attracting discounts. Request samples for lab testing to verify consistency across batches. For international shipments, confirm compliance with regional regulations like FDA or EFSA standards.
