Similarly, actinidin treatment increased the in vitro digestibility of meat proteins [83], and cooked meat proteins under simulated gastrointestinal digestion [138] and the produced angiotensin I-converting enzymes (ACE) inhibitory peptides [2] with less than 3 kDa fraction had the highest ACE inhibitory activity leading to potential anti-hypertension applications [139]. Here, ACE is linked to hypertensive disorder.
