| Summary: | North Atlantic sea cucumber (Cucumaria frondosa) or orange-footed sea cucumber is a benthic marine echinoderm found in Northwest Atlantic waters. It is harvested mainly for its edible body wall and muscle bands. The aquaphyrangeal bulb or flower is considered as a secondary marketable product and internal organs including gonads, respiratory tracts and intestine are discarded as processing by-products, which generate a high volume of biological waste. However, all the body parts of the sea cucumber are rich in protein. The objective of this research was to recover the proteins from sea cucumber tissues and produce protein hydrolysates with bioactive properties associated with antioxidative and angiotensin-I-converting enzyme (ACE) inhibitory activities following a multidisciplinary approach. Proteins were isolated from the body wall, flower and internal organs of Cucumaria frondosa using a pH-shift method. Isolated proteins were evaluated for their physicochemical properties including solubility, emulsifying ... |
