The study analyzed volatile compounds in KNBG meat using the longissimus dorsi muscle from 12 male goats (body weight: 25–45 kg). These animals were raised on a diet of rice straw and commercial pellets (15.15% crude protein, 68% total digestible nutrients) and slaughtered following standard procedures. Volatile compound analysis was conducted using gas chromatography–mass spectroscopy (4,000 GC–MS, Varian, Palo Alto, CA, USA) and electronic nose. Headspace volatiles were extracted with solid phase microextraction (SPME) fiber. Data represents area ratios (%) of the volatile compounds, but specific differentiation between high-pressure processed and control samples was not included in the presented area ratios. Data from Kang et al. (2013).
The study analyzed volatile compounds in KNBG rib meat from male and female goats aged 28 months, maintained at the Livestock Genetic Resources Center, Korea. Volatile compound analysis was conducted using the HERACLES II electronic nose system equipped with flame ionization detectors and capillary columns [MXT-5 (gas chromatography metal capillary column, 15 m, 0.53 mm ID, 5.00 μm) and MXT-1701 (gas chromatography metal capillary column, 30 m, 0.53 mm ID, 0.50 μm)]. Data are represented as peak areas (×103) with ±SD. Data from Kim et al. (2020a).
The study analyzed volatile compounds in KNBG loin meat from 24 goats (body weight: 48.6±1.4 kg; age: 4.8±1.2 years). The goats were divided into dietary (high-forage diet: 80:20; low-forage diet: 20:80) and castration [castrated (CA) vs. non-castrated (NCA)] treatment groups. Loin samples were collected post-slaughter after 24 hours of refrigeration at 4°C. Volatile compound analysis was conducted using the HERACLES II electronic nose system equipped with flame ionization detectors and capillary columns (MXT-5 and MXT-1701). Data are represented as peak areas (×103) with SEM. a–c Means within the same row with different superscript letters differ significantly at p<0.05. Data from Lee et al. (2023b).
