Definitions
- the present invention relates to a process for obtaining a peptide hydrolyzate from slaughterhouse blood proteins and a peptide hydrolyzate obtained by such a process.
- peptide hydrolysates derived from hemoglobin have been demonstrated. These include opioid, antihypertensive, analgesic, bradykinin potentiating, hematopoietic, coronary-constrictor, bacterial growth stimulating, lipid-lowering activities (Nedjar-Arroume, et al., 2008. Peptides, 29, 969-977).
- peptide hydrolysates derived from blood could potentially be used in many fields, for example in the food, as a preservative, or therapeutic or nutraceutical, as an alternative to antibiotics, especially in animal nutrition, but also as active substances intended to destroy, repel or render harmless the pests, to prevent their action or to combat them in agriculture.
- the nucleic acids likely to be obtained from poultry blood can find applications in pharmacy, in cosmetics, in nutrition and in the field of diagnostics.
- the methods for obtaining peptide blood hydrolysates of the state of the art involve, after blood collection, a separation step of the plasma and the cruor.
- the cruor which is almost exclusively composed of hemoglobin, is preserved and the hemoglobin it contains is then subjected to enzymatic digestion using an enzyme, for example porcine pepsin.

- This characteristic of the process contributes to the eco-responsibility characteristic since it uses the totality of the raw material. It makes it possible to obtain a hydrolyzate enriched with peptides not only derived from hemoglobin but also from plasma proteins.
- anticoagulant such as citrate or sodium phosphate, makes this raw material homogeneous and also prevents the loss of material by coagulation phenomena.
- the enzymatic hydrolysis step is carried out at ambient temperature at an acidic pH, preferably between 3 and 4, so as to preserve the homogeneous medium, without precipitation of the heme, with complete hydrolysis of the proteins and chains. alpha and beta hemoglobin without loss of peptides.
- Stopping the hydrolysis is done in an alkaline medium by adding base to a basic pH, preferably between 8.5 and 10, in order to irreversibly inactivate the enzyme and to maintain a homogeneous medium.
- the bleaching step does not involve organic solvents, membranes, adsorbents, bleaches, high pressure treatments, or other complex intermediate step that can reduce the yield of peptides.
- This step is carried out in a simple and effective manner, by lowering the pH to an acidic value, preferably between 4 and 5. During this step, 100% of the theme is precipitated and all the peptides obtained at the end of the hydrolysis is preserved.
- the separation of the products of the hydrolysis is carried out by a physical separation method of the type known to those skilled in the art.
- the peptide hydrolyzate fraction obtained at the end of the process contains more than 99.9% peptides and less than 0.1% heme.
- the fraction enriched in peptides is directly recoverable. It can be advantageously neutralized, demineralised, concentrated, dried at low temperature and / or lyophilized if necessary.
- the whole blood is blood of porcine, bovine, ovine, equine, rabbit or avian origin, poultry, or a mixture, preferably bovine or porcine blood.
- this mixture is for example composed of 70% of bovine blood and 30% of pig blood.
- the enzyme used during the enzymatic hydrolysis step is an active proteolytic enzyme at acidic pH, preferably porcine pepsin.
- porcine pepsin EC 3.4.23.1 (classification according to the Enzyme Commission).
- the enzymatic hydrolysis reaction is carried out according to an enzyme / substrate ratio (E / S) of between 1/10 and 1/1000.
- the method comprises, prior to the enzymatic hydrolysis, a blood dilution step, so as to obtain a solution which contains between 1 and 12% by weight of hemoglobin.
- this dilution is carried out using water.
- the pH adjustments to acid values are carried out using hydrochloric acid, phosphoric acid or sulfuric acid mixture.
- the adjustment of the pH to a basic value is, for its part, carried out using hydroxide or sodium carbonate, calcium hydroxide, ammonium hydroxide or a mixture of said compounds.
- the method is carried out on blood rich in nucleic acids such as poultry blood and comprises, after stopping the hydrolysis reaction and before the bleaching of the hydrolysis product, a step of separating the nucleic acids from the remainder of the hydrolysis product and recovering this fraction.
- the separation of the nucleic acids from the rest of the product of the hydrolysis is carried out by a physical separation method of the type known to those skilled in the art, for example by centrifugation.
- the fraction obtained at the end of the process contains more than 93% of nucleic acids.
