Edible seaweed Edible seaweed Edible seaweed, or sea vegetables, are algae that can be eaten and used in the preparation of food. They typically contain high amounts of fiber. They may belong to one of several groups of multicellular algae: the red algae, green algae, and brown algae. Seaweeds are also harvested or cultivated for the extraction of polysaccharides such as alginate, agar and carrageenan, gelatinous substances collectively known as hydrocolloids or phycocolloids. Hydrocolloids have attained commercial significance, especially in food production as food additives. The food industry exploits the gelling, water-retention, emulsifying and other physical properties of these hydrocolloids. Most edible
Edible algae vaccine and provided oral vaccination in mice, but was hindered by low vaccine antigen expression levels. Proteins expressed inside the chloroplast of algae (the most common site of genetic engineering and protein production) do not undergo glycosylation, a form of posttranslational modification. Glycosylation of proteins that are not naturally modified like the malaria vaccine candidate pfs25 can occur in common expression systems like yeast. Edible algae vaccine Edible algae based vaccination is a vaccination strategy under preliminary research to combine a genetically engineered sub-unit vaccine and an immunologic adjuvant into "Chlamydomonas reinhardtii" microalgae. Microalgae can be freeze-dried and administered orally. While
