Description

.Beta.-Carrageenan is a high-purity, sulfated polysaccharide derived from specific red seaweeds, valued for its exceptional gelling, thickening, and stabilizing properties. This hydrocolloid is crucial for creating specific, firm, and brittle gel textures in a wide range of industrial formulations. It is a key functional ingredient for manufacturers in the food, pharmaceutical, and personal care industries seeking reliable texture control and product stability.

Application

• Food Industry: Used as a gelling agent in dairy desserts (e.g., flans, puddings), confectionery, and water-based gels. It acts as a stabilizer and thickener in sauces, dressings, and processed meat products to improve texture and moisture retention.
• Pharmaceuticals: Employed as a gelling agent and controlled-release matrix in tablet formulations, topical gels, and sustained-release drug delivery systems.
• Personal Care & Cosmetics: Serves as a viscosity modifier and stabilizer in toothpastes, creams, lotions, and hair gels, providing a smooth, non-sticky texture.
• Biotechnology & Microbiology: Used as a gelling agent in culture media for the growth of microorganisms and plant tissues.
• Technical Applications: Functions as a binder and stabilizer in industrial products such as air freshener gels, water-based paints, and ceramic glazes.

Quality Control

Our .Beta.-Carrageenan is produced and tested to meet stringent quality standards suitable for food, pharmaceutical, and technical applications. We ensure compliance with relevant specifications, including FCC (Food Chemicals Codex) and other industry-grade requirements. A comprehensive Certificate of Analysis (COA) detailing purity, viscosity, gel strength, and microbiological parameters is provided with every batch to guarantee consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption.
