The sea offers a great source of plant derived proteins. Lab Manager reported, there are plant-based alternative protein options which have emerged from the sea. Three alternative protein sources which many people have not heard about are algae-derived proteins, super seaweeds, and duckweed.
Algae-derived proteins are a diverse group of photosyntehetic organisms which are primarily aquatic. They contain chlorophyll and generate oxygen. As a matter of fact about half of the photosynthesis which happens on Earth is from algae. Algae are nutrient dense with varied amounts of vitamins C, E, A, folate, calcium, iron, iodine, omega-3 fatty acids, carbohydrates, protein, and many other nutrients. The protein content of algae ranges from 50 percent to 70 percent.
Red seaweed generally has the highest protein content of all seaweeds. The red species nori has been found to contain the greatest amount of protein with 100 grams of nori containing as much as 50 grams of protein. The amino acid profile of nori is similar to that of beans or peas. Nori also has a significant amount of omega-3 fatty acid and is a very good source of vitamin B12. Sushi rolls are commonly wrapped in nori. Nori is also sprinkled into soups and noodle dishes.
Duckweed is the smallest flowering plant which has been found in the world. It has a protein contents of up to 45 percent. This ranks among the highest protein levels seen in the plant kingdom. People in Vietnam, Laos, Thailand, and parts of Africa have been eating various types of duckweeds for centuries.
The Institute of Food Technologies reports as the demand for protein increases more alternatives are needed to satisfy the protein needs of people. The consumption of protein sources which are not derived from animals and which are free of known allergens are becoming more common. It is projected they will constitute 50 percent of the market for alternative protein by 2054. The expanding market for tasty and nutritious plant based proteins from the sea is interesting. However to maintain a good source for this growing source of protein for people we must move aggressively to clean up the environment and preserve our seas.
