Dried seaweed refers to a variety of edible seaweeds that have been collected from the ocean, dried and processed for consumption. These seaweeds are widely used in various cuisines worldwide and come in a variety of forms, including sheets, flakes, and strips. The term “sea vegetables,” or dried seaweed, refers to a variety of marine algae species that are collected, dried, and then often eaten for their high nutritional value. They come in a variety of colors – red, green, brown and black – and provide food for marine life.
Vitamins (A, C, E, and K), minerals (iodine, calcium, iron, and magnesium), antioxidants, and fiber are some of the nutrients that are high in seaweed. Dried seaweed is a versatile, high-nutrition food additive that, when included in a balanced diet, provides many health benefits in addition to giving food a unique flavor.
Seaweeds (macroalgae) are marine bioresources rich in a range of valuable ingredients that are used in food, pharmaceutical, cosmetic, and animal feed applications. They are viewed as a low-investment crop and are readily available in coastal environments. Apart from macronutrients, edible seaweeds are valued for the abundance of naturally occurring bioactive compounds like phenolics, flavonoids, and antioxidants, finding numerous applications in the food and nutraceutical industries.↗️
