|Title:||Assessment of the functional properties of protein extracted from the brown seaweed Himanthalia elongata (Linnaeus) S. F. Gray||Authors:||García-Vaquero, Marco; López-Alonso, Marta; Hayes, Maria||Permanent link:||http://hdl.handle.net/10197/8228||Date:||2016||Online since:||2017-06-29T01:00:11Z||Abstract:||A protein extract from the brown seaweed Himanthalia elongata (Linnaeus) S. F. Gray was prepared and its functional properties, colour and amino acid composition were assessed for its potential future use by the food industry. The total content of amino acids was determined as 54.02 ± 0.46 g amino acids/kg dry weight, with high levels of the essential amino acids lysine and methionine. SDS-PAGE showed 5 protein bands with molecular weights of 71.6, 53.7, 43.3, 36.4 and 27.1 kDa. The water holding capacity and oil holding capacity were determined as 10.27 ± 0.09 g H2O/g and 8.1 ± 0.07 g oil/g respectively. Foaming activity and stability were higher at alkaline pH values. The emulsifying capacity and stability of the extract varied depending on the pH and oil used. These results demonstrate the potential use of Himanthalia elongata protein extract in the food industry.||Funding Details:||NutraMara – Marine functional foods research initiative||Type of material:||Journal Article||Publisher:||Elsevier||Journal:||Food Research International||Volume:||99||Issue:||Part 3||Start page:||971||End page:||978||Copyright (published version):||2016 Elsevier||Keywords:||Macroalgae; Functional properties; Foaming properties; Emulsifying properties; WHC; OHC; Colour; Color; Seaweed; Himanthalia elongata; Protein extract; Amino acid analysis; Tris-tricine SDS-PAGE; Techno-functional properties||DOI:||10.1016/j.foodres.2016.06.023||Language:||en||Status of Item:||Peer reviewed||This item is made available under a Creative Commons License:||https://creativecommons.org/licenses/by-nc-nd/3.0/ie/|
