2. The Source of Organic Carrageenan

Red Seaweeds: Organic carrageenan is primarily sourced from red seaweeds. These seaweeds are carefully harvested from their natural habitats. The choice of the right species of red seaweeds is crucial as different species can yield carrageenan with varying properties. For example, Chondrus crispus and Gigartina stellata are some of the common sources.

Sustainable Harvesting: The harvesting process of these seaweeds is carried out in a sustainable manner. This ensures that the natural ecosystems are not disrupted. Harvesters follow strict regulations to protect the marine environment and maintain the balance of the seaweed populations. For instance, they avoid over - harvesting in a particular area and monitor the growth cycles of the seaweeds.

3. The Extraction Process

Initial Cleaning: Once the seaweeds are harvested, the first step in the extraction process is thorough cleaning. This helps to remove any impurities such as sand, shells, and other debris that may be attached to the seaweeds. The cleaning process is usually carried out using clean seawater or freshwater, depending on the specific requirements of the extraction facility.

Alkaline Treatment: After cleaning, the seaweeds are subjected to an alkaline treatment. This treatment helps to break down the cell walls of the seaweeds, making it easier to extract the carrageenan. Commonly used alkalis include potassium hydroxide or sodium hydroxide. The concentration and duration of the alkaline treatment are carefully controlled to ensure optimal extraction without damaging the carrageenan structure.

Extraction with Hot Water: Following the alkaline treatment, hot water extraction is carried out. The seaweeds are immersed in hot water, which helps to dissolve the carrageenan. The temperature of the hot water is typically maintained between 70 - 90°C. This step is crucial as it determines the yield and quality of the extracted carrageenan.

Filtration and Purification: Once the carrageenan is dissolved in the hot water, the solution is filtered to remove any remaining solid particles. This filtration process can involve the use of filters with different pore sizes to ensure complete removal of impurities. After filtration, the carrageenan solution may undergo further purification steps to remove any unwanted substances such as salts or proteins.

Drying and Powder Formation: The purified carrageenan solution is then dried to obtain the powder form. This can be done using various drying methods such as spray drying or freeze - drying. Spray drying is more commonly used in industrial settings due to its efficiency. The dried carrageenan powder is then carefully packaged to protect it from moisture and other contaminants.

4. Properties of Organic Carrageenan Extraction Powder

Solubility: Organic carrageenan extraction powder has excellent solubility in water. It forms a viscous solution when dissolved in water, which is one of its key properties that make it useful in various applications. The solubility can be affected by factors such as temperature and pH. For example, at higher temperatures, it dissolves more readily.

Gel - forming Ability: One of the most notable properties of carrageenan is its gel - forming ability. It can form gels at different concentrations and in the presence of certain cations such as potassium or calcium. These gels can range from soft and elastic to firm and brittle, depending on the type of carrageenan and the conditions of gel formation.

Stability: Organic carrageenan extraction powder is relatively stable under normal storage and processing conditions. It can withstand a certain range of temperatures, pH levels, and shear forces. However, extreme conditions such as very high or very low pH values can affect its stability and functionality.
