Definitions
- the invention consists in the production of bioactive egg products derived from egg white proteins. These give rise, after an enzymatic treatment, to peptides with inhibitory activity of the angiotensin converting enzyme (TECA activity) in vitro and / or antihypertensive and / or antioxidant activity, which can be applied in the food and pharmaceutical industry.
- TECA activity angiotensin converting enzyme
- Bioactive peptides correspond to fragments that are inactive within the precursor protein, but which can be released by hydrolysis in vivo or in vitro and, in this way, exert different physiological functions in the body. Since its discovery, in 1979, peptides have been described food protein derivatives with different biological activities: antihypertensive, antithrombotic, opioid, antioxidant, immunomodulant, etc.
- bioactive peptides those that exert antihypertensive activity through the regulation of the renin-angiotensin system (T. Takano, Milk derived peptides and hypertension reduction, International Dairy Journal, 1998, 8: 375-381).
- the high incidence of coronary diseases in the population is notorious, and the treatment of hypertension is one of the most used strategies to reduce the risk of cardiovascular diseases.
- the mechanism of action of these peptides has been explained by the inhibition of the angiotensin-converting enzyme (RCT), which catalyzes the formation of angiotensin IL an octapeptide with a potent vasoconstrictor activity and, in addition, inactivates bradykinin, which produces vasodilation.
- RCT angiotensin-converting enzyme
- TECA Different peptides with ACE inhibitory activity
- WO01 / 85984 Enzymatic treatment of whey proteins for the production of antihypertensive peptides, the resulting produets and treatment of hypertension in mammals
- caseins US6514941, Method of preparing a casein hydrolysate enriched in anti-hypertensive peptides
- Another group of bioactive peptides of great importance is that of peptides with anti-oxidant activity.
- Aging and various pathologies are related to the oxidation of cellular components, such as lipids, proteins or DNA, so the inclusion of antioxidants in the diet has a preventive character.
- these compounds can prevent the oxidation of fats, avoiding the appearance of unpleasant flavors in food.
- Yoshikawa Isolation and characterization of ovokmin, a bradykinin Bl agonist peptide derived from ovoalbumin, Peptides, 1995, 16: 785-790
- ovokinin an isolated octapeptide of an ovalbumin hydrolyzate with pepsin (FRADHPFL)
- FRADHPFL ovalbumin hydrolyzate with pepsin
- Ovokinin had antihypertensive activity when administered orally to spontaneously hypertensive rats (SHR) at doses of 100 mg kg (H. Fujita, R. Sasaki and M.
- Yoshikawa Potentiation of the antihypertensive activity of orally administerrd ovokinin, a vasorelaxing peptide derived from ovalbumin, by emulsification in egg phosphatidyl-choline, Bioscience Biotechnology and Biochemistry, 1995, 59: 2344-2345).
- Yoshikawa A novel anti-hypertensive peptide derived from ovalbumin induces nitric oxide-mediated vasorelaxation in an isolated SUR mesenteric artery, FEBS Letters, 1999, 452: 181-184), purified from a ovalbumin hydrolyzate with chymotrypsin, a hexapeptide corresponding to fragment 2-7 of ovokinin (RADHPF, ovokinin (2-7)) that exerted a potent vasodilator action in SHR at a dose of 10 mg / kg. Subsequently, ovokinin analogs (2-7) were synthesized in order to increase their antihypertensive activity.
- ovokinin analogs (2-7) were synthesized in order to increase their antihypertensive activity.
- RPFHPF and RPLKPW showed 10 and 100 times more activity than ovokinin (2-7) after oral administration to SHRs (minimum effective doses of 1 and 0J mg / kg), which was attributed to a higher Resistance to digestive tract proteases (N. Matoba, Y. Yamada, H. Usui, R. Nakagiri and M. Yoshikawa, Designing potent derivatives of ovokinin (2-7), an anti-hypertensive peptide derived from ovalbumin, Bioscience Biotechnology and Biochemistry, 2001, 65: 736-739 and Y. Yamada, N. Matoba, H. Usui and K.
- bioactive peptides consumed as part of the diet are capable of producing metabolic or physiological effects, useful in health maintenance.
- the production of bioactive peptides from egg white proteins would allow new uses to be found in the chicken egg, beyond its classic nutritional value, including the production of medicinal and nutraceutical bioproducts. This would contribute to the development of healthy, safe and high quality foods, contributing to the use and revaluation of egg products.
- the present invention consists in the production of egg products containing bioactive peptides with JJECA activity in vitro and / or antihypertensive activity and / or antioxidant activity, by enzymatic hydrolysis of egg proteins.
- Bioactive peptides are produced by hydrolysis of one or more proteins, peptides or fragments thereof, which contain the amino acid sequence of said bioactive peptides (preferably containing ovalbumin), using enzymes (preferably pepsin) and hydrolysis conditions that allow the breakdown of the protein chain in the right places for its release. They can also be obtained by chemical or enzymatic synthesis or by recombinant methods etc.
- Such peptides can be consumed as such, or from crude hydrolysates, low molecular weight concentrates or other active subfractions obtained by size separation methods or chromatographic methods.
- hydrolysates In addition to being part of food products, such hydrolysates, their fractions or peptides could also be part of pharmaceutical products. Thus, they could help in the treatment and prevention of diseases, particularly in the control of blood pressure.
- the invention extends the applications of egg proteins, contributing to their utilization and revaluation.
- the invention provides a method for producing bioactive peptides from egg white proteins.
- Said bioactive peptides are those identified with the amino acid sequences shown in the SEQ. ID. No. 1, SEQ. ID. No. 2, SEQ. ID. No. 3, SEQ. ID. No. 4, SEQ. ID. No. 5, SEQ. JO. No. 6, SEQ. ID.
