Product Introduction
Marine gum, commonly known as carrageenan, is a polysaccharide extracted from red seaweed. It functions as a thickening agent, stabilizer, and gelling agent in various food applications. The primary sources of carrageenan are several species of red algae, including Chondrus crispus, Euchema cottonii, and Euchema spinosum [1]. Carrageenan is widely utilized in the food industry, due to its ability to form gels at room temperature, and its compatibility with proteins [2].
Production Process
The production of carrageenan involves several steps. First, the red seaweed is harvested, cleaned, and then processed. The seaweed undergoes extraction in hot water, after which the seaweed cellulose is removed by filtration. The carrageenan is then recovered from the solution through precipitation with alcohol or potassium chloride. The resulting carrageenan is dried, milled, and standardized to meet specific quality requirements [3].
Product Efficacy and Function
Carrageenan functions primarily as a thickening, stabilizing, and gelling agent. It is effective in preventing the separation of ingredients in food products, enhancing texture, and controlling viscosity. Carrageenan's ability to form thermo-reversible gels makes it valuable in products where melting and re-setting are desired [4]. It also interacts with proteins, such as casein in milk, to improve the suspension and stability of dairy products [5].
Product Application Scenarios
Carrageenan sees application across a wide range of food products. It is commonly used in dairy products like ice cream, yogurt, and chocolate milk to improve texture and prevent whey separation [6]. In processed meats, carrageenan enhances binding and reduces syneresis. It is also found in non-dairy milk alternatives, jellies, sauces, and desserts where it contributes to the desired consistency and mouthfeel [7].
Packaging and Storage
Carrageenan is typically packaged in multi-layer paper bags or cardboard boxes with polyethylene liners to protect it from moisture and contamination. The product should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources to maintain its quality and prevent degradation. Under proper storage conditions, carrageenan has a shelf life of up to 24 months [8].
