Production Process

The production of agar agar is a multi-step process that begins with harvesting red seaweed. The seaweed is typically collected from coastal regions, where it grows abundantly. Once harvested, the seaweed is washed thoroughly to remove any impurities, such as sand and debris. Next, it undergoes a boiling process, where the seaweed is submerged in large vats of boiling water. This step is crucial as it extracts the agar from the seaweed's cell walls. The hot mixture is then filtered to remove any solid remnants of the seaweed, leaving behind a clear, viscous liquid. This liquid is then cooled, allowing it to form a gel. The gel is cut into strips or flakes and then dehydrated, either through sun-drying or using specialized drying equipment. The dried agar is then milled into a powder or processed into flakes or strips, depending on the desired form. Throughout the production process, quality control measures are implemented to ensure the agar agar meets the required standards for purity, gel strength, and clarity. This meticulous process results in a versatile product that is widely used in food, microbiology, and various other applications.
