8. Molecular weight distribution of peptides in the fifth breast

MALDI-TOP was used to analyze the molecular weight distributions of the products obtained by degrading the five-month-old breast meat using proteolytic enzymes. MALDI-TOF analyzes the mass of peptide fragments by treating a specific enzyme with PMF (Peptide Mass Fingerprint) analysis method and uses them to perform database search. Therefore, the PMF method is mainly used to identify proteins that have completed a genomic sequence or that have been listed in the NCBI. All amino acids in the protein have an average molecular weight of 138, but the weighted average is 128, and by condensation polymerization, the protein has an average molecular weight of 110 per unit. The unit to represent this is dalton (Dalton) and 1 kD is 1000 g / mol. For example, the average molecular weight of a protein having about 500 amino acids has a molecular weight of 55000 D, i.e. 55 kD.

As shown in FIG. 5, the molecular weight distribution of the peptides of the five-chain protein hydrolyzate was analyzed. In the graph of MALDI-TOP, the X axis represents mass (m / z) and the Y axis represents the intensity of the ionized substance. Most of the peptides showed a molecular weight distribution below m / z 500 to 1,400, although some of the impurities were included. Therefore, the five amino acid hydrolyzate peptides showed about 4 to 12 amino acid bases. Most of the peptides consisted of 10 or fewer nucleotide sequences. In terms of average molecular weight, the molecular weights of the majority of peptides consisted of 5, 6, 8, and 10 amino acid residues.

2. Measurement of DPPH radical scavenging ability

All living organisms using oxygen necessarily produce free radicals during oxidative metabolism, It is an unstable ion with one or more non-covalent electrons generated during normal body metabolism. It is closely related to aging and tissue damage associated with various inflammatory reactions such as DNA damage, protein peroxide generation and lipid peroxidation .

In the antioxidant assay, DPPH radical scavenging assay is a free radical reagent with strong oxidizing power. The antioxidative activity of DPPH by the compound donates electrons to the DPPH radical by contacting the electron donor antioxidant, Lt; / RTI &gt; Since DPPH radicals have free radicals in their oxidized forms, it is known that when they come in contact with antioxidants, which are electron donors, they get electrons to be reduced, and that the greater the antioxidant effect, the greater the degree of decolorization.

As shown in FIG. 7 (A), the DPPH radical scavenging ability of the extracts of the 5th generation crest peptide was 12.3 ± 0.7% at 10, 20, 30, 40 and 50 (mg / , 20.4%, 40.4% and 50.4%, respectively, while the three year old rooster had a radical scavenging activity of 16.7 ± 2.0%, 32.4 ± 0.7%, 55.1 ± 3.6% and 59.3 ± 1.5% 0.6%, 14.5 ± 4.1%, 27.0 ± 3.3%, 50.6 ± 8.0% and 59.2 ± 4.9%, respectively. In addition, the 3 year - old hen had 6.8 ± 0.6%, 14.7 ± 0.1%, 25.9 ± 1.0%, 57.8 ± 2.5% and 76.8 ± 1.0% radical scavenging ability at concentrations of 10, 20, 30, 40 and 50 And the radical scavenging ability was increased in a concentration dependent manner.

These results indicate that the concentration of 50 ㎎ / ㎖ of 3 - year - old hen shows higher radical scavenging ability than the results of 1 - year - old and 3 - year - old rooster and is effective in product development related to aging and tissue damage.

As shown in FIG. 7 (B), the DPPH radical scavenging activity of the extract of Pseudomonas aeruginosa was measured to be 6.6 ± 3.1 at 10, 20, 30, 40, 50 (mg / , 3, 3, 5, 10, 20, 30, 40, 50 (㎎ / ㎖) showed the radical scavenging ability of 12.3 ± 0.6%, 31.4 ± 2.5%, 61.2 ± 3.1% and 76.7 ± 3.2% Radical scavenging activity was increased by 0.9%, 6.4 ± 1.3%, 12.7 ± 0.8%, 55.5 ± 3.0% and 73.7 ± 1.6%, respectively.

The results showed that there was no difference between sexes in the winged peptone extract, and the results were similar when compared with the 50 ㎎ / ㎖ concentration of 3 - year - old hen showing the highest DPPH radical scavenging ability of the breast peptide extract. In other words, the extract of winged peptides is considered to be effective in the development of products related to aging and tissue damage.

3. Measurement of ABTS radical scavenging ability

The method of measuring ABTS radical scavenging rate is based on the principle that the absorbance of cation radicals of ABTS is reduced by antioxidant. When ABTS + produced by mixing potassium persulphate with ABTS is cleared by antioxidant, . It is also useful in that both hydrophobic and hydrophilic samples can be measured.

As shown in FIG. 8 (A), the ABTS radical scavenging ability of the extracts of the 5 th row of breast muscle peptides was 27.0 ± 1.2% at 10, 20, 30, 40 and 50 (mg / , And 46.7 ± 3.5%, 49.6 ± 6.0%, 52.5 ± 1.7% and 56.5 ± 3.6%, respectively, and the 3 year old rooster showed 33.9 ± 5 at the concentration of 10, 20, 30, 40 and 50 0.9%, 48.6 ± 2.0%, 54.1 ± 5.2%, 59.6 ± 4.0% and 67.6 ± 1.1%, respectively. In addition, the 3 year - old hen had 29.0 ± 2.7%, 51.7 ± 1.9%, 51.7 ± 3.3%, 50.9 ± 1.6% and 56.2 ± 6.0% radical scavenging ability at concentrations of 10, 20, 30, 40 and 50 And the radical scavenging ability was increased in a concentration dependent manner.

These results show little difference between the gender and the expression of breast peptide extracts. When compared to DPPH radical scavenging ability, ABTS scavenging ability was higher at low concentration. In the case of radical scavenging ability, DPPH is free radical, but ABTS is cationic radical, or because phenolic substance is different in degree of binding to two substrates and different radical scavenging mechanism is active , Respectively.

As shown in FIG. 8 (B), the ABTS radical scavenging activity of the extracts of Pseudomonas aeruginosa was measured to be 37.3 ± 1.8 at the concentration of 10, 20, 30, 40, 50 (mg / The results showed that the 3 year old hen had a radical scavenging ability of 32.7% at the concentration of 10, 20, 30, 40, 50 (㎎ / ㎖), 53.5 ± 5.7%, 66.0 ± 1.6%, 64.6 ± 0.8% and 72.4 ± 0.6% The radical scavenging activity was increased by 5.7%, 54.1 ± 2.6%, 52.8 ± 2.3%, 67.2 ± 6.4% and 70.1 ± 6.1%, respectively.

The results showed that the wing peptidic extract showed little difference between genders and the results were higher than the results of DPPH radical scavenging at low concentrations, similar to that of the breast peptide extract.
