Cheese supplementation with five species of edible seaweeds Effect on proteolysis, lipolysis and volatile compounds
The effect on the biochemical characteristics of Ibérico semi-hard cheese supplemented with Himanthalia elongata (HE), Laminaria ochroleuca (LO), Porphyra umbilicalis (PU), Ulva lactuca (UL) or Undaria pinnatifida (UP) seaweeds was investigated. Addition of 1% dehydrated seaweed to curd increased total free amino acids in LO cheese and decreased them in HE and UP cheeses at 60 days with respect to control cheese. Lipolysis was markedly enhanced in UL cheese, which showed on day 60 a 6.0-fold higher concentration of total free fatty acids than control cheese. Seventy-six volatile compounds were detected in cheeses with seaweeds and 54 in control cheese. Aldehydes and alcohols reached higher levels in the control cheese, esters and ketones in PU cheese, acids and sulphur compounds in UL cheese, hydrocarbons in HE and PU cheeses, and furans in HE and UP cheeses.
