Plant and animal proteins have been well known as sources of bioactive
peptides. Peptides might exhibit various bioactivities, including antiinflammatory,
antioxidant activities, cholesterol-lowering ability, and
blood pressure-lowering (ACE inhibitory) effects. Angiotensin-converting
enzyme (ACE) has a critical role in cardiovascular disease. The peptides
derived from food proteins are considered to be milder, safer, and easily
absorbed compared with synthetic drugs. Thus, enzyme hydrolysis peptides
from food proteins may exhibit different biological activities has been
generally accepted. Besides, peptides and proteins as antioxidants in
food are increasing due to the low costs, safety, and their inherent
nutritional and functional values. On the other hand, protein
hydrolysates with angiotensin converting enzyme inhibitory activity have shown great promise in the development of a novel therapeutics and for
functional food for preventing hypertension. With the awareness of people
on their health, more people are concerned about how to reduce the
incidence of disease, especially in antioxidation effect and decreased
blood pressure problems. Therefore, in recent years, the food contained
in the physiological active substances gradually is taken important.
Moray eels are the commercially important fish species in Taiwan. This
study was to investigate of moray eel using different enzymatic
hydrolysis the antioxidant activity and inhibition of angiotensinconverting
enzyme effect, hope new material provided as a reference for
health food.
