Abalone is a marine gastropod that is an important fishery and food industrial resource, massively maricultured in Asia, Africa, Australia, and America. Marine by-products from boiled abalone, normally discarded as industrial waste in manufacturing plants, were fractionated and concentrated using an ultrafiltration membrane system (˂ 1 kDa). In this study, the antioxidant and angiotensin I converting enzyme (ACE) inhibition effects of the boiled abalone by-products (BABs) were investigated. BABs have high antioxidant activities against free radicals (1,1-diphenyl-2-pycryl-hydrazyl (DPPH), hydroxyl, peroxyl, and superoxide radicals), reactive oxygen species (ROS) stress, and DNA damage in H 2 O 2 -treated RAW 264.7 macrophages. The structure of the purified peptide was identified to be ATPGDEG (MW 752 Da), and the ACE inhibition pattern of the peptide was found to be noncompetitive. In addition, the peptide exhibited an antihypertensive effect according to time-course measurement after oral administration to spontaneously hypertensive rats (SHR). BABs from this genus may be potential candidates for the development of unique natural substances for further industrial applications as functional foods and pharmaceuticals. [ABSTRACT FROM AUTHOR]
