Description

γ-Carrageenan is a high-purity, sulfated polysaccharide extracted from specific red seaweeds, valued for its exceptional gelling, thickening, and stabilizing properties. This hydrocolloid is crucial for achieving precise texture, stability, and mouthfeel in a wide range of formulated products. It is an essential ingredient for manufacturers in the food, pharmaceutical, and personal care industries seeking reliable, plant-based functional agents. The compound is also identified by the CAS registry number 9064-57-7.

Application

• Food & Beverage: As a gelling agent in dairy desserts (flans, puddings), a stabilizer in chocolate milk and plant-based beverages, and a texture modifier in processed meats and canned pet foods.
• Pharmaceuticals: Used as a binder and disintegrant in tablet formulations, a stabilizer in suspensions and emulsions, and a base for controlled-release drug delivery systems.
• Personal Care & Cosmetics: Functions as a thickener and stabilizer in toothpastes, creams, lotions, and hydrogel-based skincare products for its smooth texture and water-binding capacity.
• Biotechnology & Microbiology: Serves as a gelling agent for solid culture media in microbiology labs, particularly useful for thermolabile components due to its low gelling temperature.
• Technical & Industrial Applications: Employed in water-based paints, adhesives, and ceramic glazes as a rheology modifier and suspension aid.

Quality Control

Our γ-Carrageenan is produced and tested to meet stringent quality standards appropriate for its target applications, including food and pharmaceutical grades. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) to ensure traceability and compliance with specifications for parameters such as viscosity, gel strength, sulfate content, and microbiological purity. We adhere to relevant frameworks including FCC (Food Chemicals Codex) and can support compliance with cGMP for pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled 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.
