ABSTRACT
One of the challenges which the society faces in 21st century is that of being able to feed a rising world population, and algae are a possibility to relieve the problem. Their fast growth and easiness of adapting to the environment can allow the production, at great scale, of some important compounds from the nutritional viewpoint, and substances with bioactivity that help with the prevention of certain diseases. It is described that some unique characteristics that algae present differentiate them from other living organisms and could be the basis of a revolution in feeding in future. 282A useful classification of algae with regard to food is provided. Phenolic constituents of nine edible algal products are clustered by principal component analyses (PCAs) of content and algae cluster analyses (CAs), which agree, Samples group into four classes. Compositional PCA and algae CA allow classifying them and concur. The first PCA axis explains 31%, the first two, 56%, the first three, 74% variance, etc. Different algae behavior depends on 4-hydroxybenzoic acid, etc. Undaria pinnatifida wakame (W)-instant is closer to Chlorella 280pyrenoidosa than to U. pinnatifida W. Porphyra tenera is closer to Laminaria japonica than to Palmaria palmata. Algal products are functional foods rich in polyphenols, antioxidants, and bioactives. A hypothesis stated that antagonisms and synergisms exist between phenolics expecting more antagonisms than synergies.
