“…GPC is a method of separating molecules by size through elution from a column composed of porous gels such as dextran, agarose, and polyacrylamide. This method can be utilized for extracting specific proteins and analyzing the molecular weight distribution of hydrolysates ( Jia et al, 2010 ; Lee et al, 2022 ; Ting et al, 2013 ).…”

Peptides with bioactive effects are being researched for various purposes. However, there is a lack of overall research on pork-derived peptides. In this study, we reviewed the process of obtaining bioactive peptides, available analytical methods, and the study of bioactive peptides derived from pork. Pepsin and trypsin, two representative protein digestive enzymes in the body, are hydrolyzed by other cofactors to produce peptides. Bicinchoninic acid assay, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, chromatography, and in vitro digestion simulation systems are utilized to analyze bioactive peptides for protein digestibility and molecular weight distribution. Pork-derived peptides mainly exhibit antioxidant and antihypertensive activities. The antioxidant activity of bioactive peptides increases the accessibility of amino acid residues by disrupting the three-dimensional structure of proteins, affecting free radical scavenging, reactive oxygen species inactivation, and metal ion chelating. In addition, the antihypertensive activity decreases angiotensin II production by inhibiting angiotensin converting enzyme and suppresses blood pressure by blocking the AT1 receptor. Pork-derived bioactive peptides, primarily obtained using papain and pepsin, exhibit significant antioxidant and antihypertensive activities, with most having low molecular weights below 1 kDa. This study may aid in the future development of bioactive peptides and serve as a valuable reference for pork-derived peptides.

Jeju Sasa borealis (S. borealis) is indigenous to the Halla Mountain area of Jeju Island, Republic of Korea. However, its dominance has retarded the development of other plant species and lowered biodiversity in this region. The aim of this study was to determine whether S. borealis silage (SS) supplementation affects the chemical composition and antioxidant activity in the fresh meat of Korean native goats (Capra hircus coreanae). The experiment was conducted on 12 Korean native goats at the finisher stage. The feeding groups were the Control (total mixed ration, TMR) and the Treatment (80% TMR + 20% SS). The animals were adapted for two weeks and then subjected to a six-month breeding experiment. Meat samples were excised from the neck, loin, rib, front leg, and hind leg of the slaughtered animals. The meat derived from the treatment group contained more taurine and anserine than that derived from the control group. Both groups did not significantly differ in terms of ω-6/ω-3 fatty acid ratio. The loin and front leg of the treatment group contained significantly higher vitamin E levels than those of the control group. DPPH, ABTS, and FRAP analyses disclosed that the loin and front leg had significantly higher antioxidant activity (p⟨0.05) than the other parts. Moreover, the loin and front leg cuts of the treatment group had higher antioxidant activity than those of the control group. The present study demonstrated that S. borealis supplementation could effectively improve Korean native goat meat quality.
