Advanced Search Abstract Bioactive peptides BP are organic substances formed by amino acids joined by covalent bonds known as amide or peptide bonds. Although some BP exist free in its natural source, the vast majority of known BP are encrypted in the structure of the parent proteins and are released mainly by enzymatic processes. Some BP have been prepared by chemical synthesis. BP play a significant role in human health by affecting the digestive, endocrine, cardiovascular, immune, and nervous systems. BP are considered the new generation of biologically active regulators; they can prevent oxidation and microbial degradation in foods and also improve the treatment of various diseases and disorders, thus increasing the quality of life.

In vivo, encrypted peptides can be liberated during gastrointestinal GI digestion by enzymes such as trypsin or by microbial enzymes. In vitro, BP can also be released during food processing or ripening by microbial enzymes e. Lactobacillus helveticus Gobbetti et al. BP have been identified and isolated from animal and vegetal sources and are abundantly present in protein hydrolysates and fermented dairy products. Currently, BP and nutraceutical proteins are being developed to improve human health by preventing or alleviating medical conditions such as coronary heart disease, stroke, hypertension, cancer, obesity, diabetes, and osteoporosis Gilani et al.

Peptides from animal sources Peptides derived from animal proteins have been attributed to different health effects Bhat et al.

Although blood disposal is a severe problem for meat processors, serum albumin, the main blood protein has received little attention. In a recent study, serum albumin was hydrolyzed using different concentrations of trypsin and the peptide sequences in the hydrolysates presented the following activities: angiotensin-converting enzyme ACE inhibition antihypertensive activity , DPP-IV inhibition glucose regulation , and antioxidation Arrutia et al.

Blood obtained from the slaughterhouse is part of the meat production food chain that has not been fully exploited. Haemoglobin fragments can have a profound physiological function. Degradation step coupled with excretion afforded shorter peptides from red blood cells. Both the primary and the secondary proteolysis products were subjected to further stepwise C- and N-terminal chain shortening, giving rise to families of closely related peptides that are found in animal tissue extracts Ivanov et al.

Peptides from vegetal sources Two excellent works on BP from vegetal sources have been recently published Malaguti et al. BP produced during in vitro GI digestion of soybean seeds and soy milk have been investigated Singh et al.

The analysis was performed on extracted protein samples from soybean seeds and milk or directly on untreated soy milk. The results indicated that soybean proteins experimented degradation during GI digestion generating a large number of BP, some with established activity, and some with predicted antimicrobial activity. Endogenous proteases were also used to investigate the presence of peptides Singh et al. Peptides found in soy milk samples could be formed during food processing Capriotti et al.

Soy hydrolysate and the soy-fermented foods, natto and tempeh, were digested with a variety of endoproteases such as pronase, trypsin, Glu C protease, plasma proteases, and kidney membrane proteases to generate oligopeptides, most likely derived from glycinin, a soy protein.

Digestion of natto with pronase provided a peptide with ACE inhibitory activity and a peptide with surface active properties. Likewise, hydrolysis of natto with kidney membrane produced a peptide with ACE inhibitory activity, and a peptide with anti-thrombotic activity which resembles hirutonin, a previously described synthetic thrombin inhibitor Gibbs et al.

Cereal grains that have been used in human diets for a long time such as wheat, barley, rice, rye, oat, millet, sorghum, and corn, are a rich source of BP Malaguti et al. Scientific evidence has shown the health benefits of consuming whole grains for preventing diseases such as diabetes, cancer, and cardiovascular diseases.

Wheat and oat showed the presence of ACE inhibitory peptides and dipeptidyl peptidase inhibitor, as well as peptides with anti-thrombotic, antioxidant, hypotensive, and opioid activities. On the other hand, wheat and rice have proteins with peptidic sequences showing anticancer activity. Wheat and barley showed the greatest diversity and abundance of peptides with potential biological activity among the cereal proteins Malaguti et al.

Further research is required to establish the mechanism to release the active peptides sequences from cereal grains.

They can be formed from the N-terminal amino acid residues of a linear peptide or protein and have been identified in various foods, particularly in roasted coffee, cocoa, roasted malt, chicken essence, and fermented foods such as beer, distillation residue of awamori, and aged sake.

DKPs can also be found in whey protein hydrolysates, and some beverages—therefore DKPs have been considered as a functional component. It has been reported that some DKPs found in the distillation residue of awamori show antioxidant activity Kumar et al. Cyclo -Phe-Phe present in chicken essence acted as a dual inhibitor of the serotonin transporter and acetylcholinesterase. On the other hand, cyclo -His-Pro displayed effects such as food intake inhibition and body weight reduction in rats, therefore it might influence human biological regulation Yamamoto et al.
