Seaweed is highly regarded as a valuable gift from the sea, renowned for its abundant nutritional properties that are beneficial for our overall well-being. In the market, there are three main varieties of seaweed that are frequently mentioned: fresh seaweed, dried seaweed, and seaweed extract. In this article, we will explore the distinctive characteristics that set each type apart from one another.

What are the Benefits of Fresh Seaweed?

Fresh seaweed is a seaweed that is freshly harvested and immediately placed in a separate tank filled with seawater to promote healing of the cuts. Subsequently, it is carefully stored in a sealed container to maintain its freshness and preserve its quality. It is advisable to consume the fresh seaweed within a period of 3-5 days from the harvesting date to ensure optimal taste and freshness.

Along with the traditional refrigeration method, a freezing technique is now available to preserve fresh seaweed for a period of 3 – 4 weeks. However, it should be noted that this method may cause a slight decrease in the seaweed’s initial freshness.

The current market price for fresh seaweed typically ranges between 200,000 and 300,000 VND per kilogram.

Understanding Dried Seaweed and Seaweed Extracts

In reality, dried seaweed and seaweed extract are essentially the same. Dried seaweed is produced from fresh seaweed that is harvested and then subjected to a drying or water extraction process. This serves to decrease the water content within the seaweed and enhance its shelf life.

After processing, dried seaweed can be stored in saltwater packs weighing approximately 100g or 200g. Alternatively, it can be preserved in vacuum packaging, allowing for a shelf life of up to 6-8 months when stored in the refrigerator.

Dried seaweed retains its taste and nutritional value without significant alteration. To rehydrate it, simply soak the seaweed in water, restoring its freshness and crispiness.

The current market price of dried seaweed ranges from 500,000 to 600,000 VND per kilogram.
