Seaweed may provide new source of functional ingredients

Posted On: July 22, 2011

Seaweed and other macroalgae could rival milk products as sources of functional ingredients such as heart healthy bioactive peptides, according to a new study. 

The review of almost 100 scientific studies, published in the Journal of Agricultural and Food Chemistry, reports that some seaweed proteins have the same effects as the bioactive peptides found in milk products and dairy products, and work to reduce blood pressure in a similar way to ACE inhibitor drugs.

“Due to the environment in which they grow, macroalgae produce unique and interesting biologically active compounds,” said Maria Hayes and colleagues from Teagasc Food Research Centre, Ireland and the University of London, UK.

“The variety of macroalga species and the environments in which they are found and their ease of cultivation make macroalgae a relatively untapped source of new bioactive compounds, and more efforts are needed to fully exploit their potential for use and delivery to consumers in food products,” they added.
