Abstract
According to reports from the World Health Organization (WHO), hypertension is considered the most common cardiovascular risk factor, affecting 25 to 30% of the world's population. One of the primary causes of hypertension is angiotensin-converting enzyme-I (ACE), which plays a crucial role in regulating blood pressure through the modulation of the renin-angiotensin-aldosterone system. Consequently, there is a wide range of drugs available that can inhibit ACE. However, these drugs can cause adverse side effects such as cough, headache, skin rash, altered taste, angioedema, nausea, and allergic reactions. For this reason, there is considerable interest in obtaining ACE inhibitors from natural sources that reduce side effects and dependence on drugs. Specifically, bioactive peptides present in enzymatic protein hydrolysates have shown anti-hypertensive properties by inhibiting ACE, making them a promising alternative in the prevention and treatment of hypertension. The objective of this study was to evaluate the ACE inhibitory activity (in vitro) of enzymatic hydrolysates obtained from cocoa bean proteins (albumin and globulin), with the purpose of considering them as a natural source of potential anti-hypertensive agents. The results demonstrated that the enzymatic treatment (with alcalase) of albumin and globulin from cocoa beans is a viable bioprocess for producing hydrolysates with ACE inhibitory activity. In particular, hydrolysates and peptide fractions (< 3000 Da) with greater ACE inhibitory capacity were generated from globulin, making them a suitable choice for designing functional foods.
