Chapter 10 - REMOVED: Proteins extracted from brown seaweed and their potential uses as foods and nutraceuticals

Abstract

Isolation and utilisation of proteins from seaweeds have been a novel trend in the world at present due to the increasing demand for healthy non-animal proteins. The much attention of scientific community has been paid on the protein derived from seaweed Undaria pinnatifida due to their high nutritional quality and bioactivity. This article aims to provide an integrated overview on methods of extraction, isolation and purification of proteins from U. pinnatifida. Proteins’ composition, nutritional value, nutraceutical and food potentials will also be reviewed, with an interest to stimulate further research to optimise the utilisation of U. pinnatifida derived proteins. Proteins of U. pinnatifida can be extracted by conventional, as well as improved modern techniques. Potential food applications of U. pinnatifida derived proteins are nutritional component in human diet, food ingredients and additives, alternative meat and meat analogues and animal and fish feed. Excellent bioactivities possessed by proteins of U. pinnatifida enable the use of these proteins in various nutraceutical applications, including antioxidant, antihypertension, anticoagulant, anti-diabetes, antimicrobial and anti-cancer. Hence, more research works are crucial to be done in order to facilitate and promote the emerging novel foods and nutraceuticals, using proteins from seaweed U. pinnatifida.
