Description

Rubusoside is a high-intensity, natural sweetener and steviol glycoside isolated from the leaves of *Rubus suavissimus* (Chinese sweet tea). This compound is valued for its clean, sweet taste profile, which is approximately 100-200 times sweeter than sucrose, and its potential health benefits as a non-caloric sweetening agent. It is primarily sought after by manufacturers in the food & beverage, nutraceutical, and pharmaceutical industries for developing sugar-reduced and functional products.

Application

• Food & Beverage: Used as a natural, high-intensity sweetener in beverages, dairy products, confectionery, and baked goods to reduce sugar and calorie content.
• Dietary Supplements & Nutraceuticals: Incorporated into weight management formulations, vitamin blends, and health supplements as a non-caloric sweetening component.
• Pharmaceuticals: Employed as a taste-masking agent or excipient in syrups, chewable tablets, and oral suspensions to improve palatability.
• Functional Foods: Applied in products targeting blood sugar management and oral health due to its potential bioactive properties.
• Cosmetics & Oral Care: Utilized in toothpaste, mouthwash, and lip care products for its sweetening effect without promoting dental caries.
• Research & Development: Serves as a reference standard or key intermediate in biochemical and food science research for studying sweet taste receptors and natural product chemistry.

Quality Control

Our Rubusoside is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications for food and nutraceutical applications. A Certificate of Analysis (COA) detailing purity, heavy metals, residual solvents, and microbiological parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent moisture absorption and potential degradation.
