  • Pork belly meat is one of the most preferred food items for many Korean people. The odorants released from cooking of pork belly meat were measured by three kinds of cooking methods (Charcoal-grill (C), Electric Pan (E), and Gas burner-pan (G)). A total of 16 target compounds including carbonyl compounds, volatile organic compounds, and poly aromatic hydrocarbon were selected and analyzed for comparative purposes. Their emission concentrations were quantified using HPLC-UV, GC-MS, GC-TOF-MS, etc. The gas samples collected by Charcoal-grill cooking showed generally enhanced concentrations of most target compounds among all three kinds of cooking methods. In Charcoal-grill, concentration of benzene, formaldehyde and pyrene went up to 543, 516, and 402 ppb, respectively. It the results are compared in terms of the sum of odor intensity, the highest value (4.25) was also seen from Charcoal-grill. The results of this study confirm that the significantly reduced emission of harmful pollutants can be attained, it pork belly meat is cooked by the Gas or electric pan instead of Charcoal-grill.

  • This experiment was carried out to investigate characteristics of pork quality according to various producing district. The results of whole component analysis of pork according to diverse producing district were showed high level of fat content in Jeju island-belly and shoulder loin than other pork samples. And saturated fatty acid contents of Jeju island-belly and shoulder loin of pork were showed 46.6 and 41.6%, respectively, and unsaturated fatty acid contents of Jeju island-belly and shoulder loin of pork were showed 50.3 and 58.4%, respectively. Chungbuk-pork was relatively showed high level of cholesterol content than other pork samples. On the other hand, cholesterol contents of Jeju island-belly and shoulder loin of pork were showed 565.6 and 507.6 ${\mu}g/g$, respectively. Skatole contents of Jeju island-belly and shoulder loin of pork were showed low level(0.013 and 0.065 ${\mu}g/g$) than other pork samples. This results mean that Jeju island-belly and shoulder loin of pork have less order than other pork samples. The chewiness of texture that consumers feel the biggest difference in palatability of meat showed significantly high level(376.5 g) in Jeju island-belly of pork(p<0.05). This result represent that Jeju island-belly of pork have the best sense of the texture than other pork samples. $L^*$(lightness) value of ground pork was generally showed high value in belly than shoulder-loin of pork. However, $a^*$(redness) value of ground pork showed high value in shoulder-loin than belly of pork. And there was no significant difference in $b^*$(yellowness) value among the samples(p>0.05). The results of sensory test(taste, flavor, texture and palatability) from pork according to various producing district showed good flavor and palatability in Jeju island-belly of pork but there was no significant difference among the samples(p>0.05).

  • This study was carried out to some properties and curring effect of drip obtained from frozen-thawed park loin ham belly and imported belly by thawing process at 4$^{\circ}C$. Moisture content and pH value of drips were 88.05~90.85% and 5,72~6.05 and do not show significant differences between each samples. Protein contents were 11.07, 8.85, 8,76 and8,13% in the drips from domestic pork loin, ham, belly and imported belly, respectively. Approximately 99% of the drip were constituted with moisture and protein in any part of domestic pork and imported belly. Glutamic acid proline glycine, alanine and lysine were the predominant amino acid in the drips. Curing process of the drip by nitrite increased the pH value and total amino acid content. The residual nitrite decreased during the period of curing and total plate counts in drip with nitrite did not reach 1$\times$105CFU/g until 7 days.

  • This study was performed to determine the meat quality characteristics of pork loin and belly from 3 different three-way crossbred pigs: Yorkshire ${\times}$ Landrace ${\times}$ Duroc (YLD), Yorkshire ${\times}$ Chester White ${\times}$ Yorkshire (YCY), and Yorkshire ${\times}$ Berkshire ${\times}$ Duroc (YBD). Each of the twenty crossed pigs were randomly selected with their live weights at the range of 110-120 kg. After being slaughtered and cooled at $0^{\circ}C$ for 24 h in a chilling room, the parts of loin and belly on the left side of the cooled carcasses were cut and prepared for analysis. The intramuscular fat contents of the loins from YLD were higher than those of the other crossbreds (p<0.05), and the YCY bellies had the highest moisture contents (p<0.05). Water holding capacity (WHC) of the loins from YCY were higher than the other crossbreds (p<0.05). Shear force values of the YBD loins were higher than the others (p<0.05). The TBARS values of YCY loins were significantly lower than the others at 0 d, but the difference disappeared after 14 d of storage. Sensory scores of YLD were ranked higher than the YCY or YBD in both the loins and bellies (p<0.05). The relatively high sensory values of YLD crossbred pork could be explained by the better WHC, the low shear forces, and the higher fat contents. The results indicated that the meat qualities could be altered by three-way crossbreeding.

  • The physicochemical characteristics and oxidative stability of wet-aged and dry-aged pork cuts were investigated at different aging periods (1, 7, 14 and 21 d). Samples were assigned into four groups in terms of shoulder blade-wet aging (SW), shoulder blade-dry aging (SD), belly-wet aging (BW), and belly-dry aging (BD). SD showed significantly higher pH at 21 d of aging than the other samples. Wet-aged cuts had significantly higher released water (RW) %, lightness ($L^*$) and shear force compared to the dry-aged meats. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis showed greater degradation of proteins for dry-aged cuts than the wet-aged cuts. At the end of aging, wet-aged cuts showed significantly lower thiobarbituric acid-reactive substances (TBARS) value than the dry-aged samples, indicating higher oxidative stability for wet-aged pork cuts. However, dry-aging led to higher degradation of proteins resulting in increased water-holding capacity (WHC) and decreased shear force value.

  • The objective of this experiment was to compare tile effect of feeding the commercial feeds (control) or fermented food waste feeds (FEWF) on consumer's acceptability and preference of pork belly. The bellies from carcasses of gilts and barrows were used. The consumers evaluated raw meat for color, freshness, fat amount (5=too much fat; 1= not enough fat), fat acceptability and overall acceptability on 5-point stale (5=most desirable; 3=moderate; 1=least desirable) and grilled belly for flavor, taste, texture, juiciness and overall acceptability on 5-point scale (5=most desirable; 3=moderate: 1=least desirable). Raw belly of control had higher scores in color than belly fed FFWF. However, there were no differences between treatments for freshness, fat contents, acceptability of fat contents and overall acceptability (p>0.05). There were no differences in any sensory trait between control and FFWF belly after cooking (p>0.05). Mean scores for preference or overall-liking of raw and cooked belly also were not significantly different between two groups (p>0.05). This results mean that feeding FFWF to pork didn't change the sensory Properties of belly meat.

  • Pork belly meat and mackerel are popular meals in Korea. Although a lot of people enjoy cooking these food, there have been some reports that generated organic particles during cooking could be thereas on of lung cancer of nonsmoking housewives. In addition, some experiments show that carcinogens may be included in meat and fishes which we eat usually. For this reason, particle size and concentration in formation during cooking are necessary to figure out the relationship between particles and the diseases. Thus, we identify number concentrations and size distributions of generated nano aerosol in cooking with respect to time, hood operation, and distance between cooking and measurement locations. The maximum concentrations of nano aerosol(diameter sizes are between 10 to 700nm)are decreased after the cooking from $8{\times}10^6{\sharp}/cm^3$ to zeroth order in pork belly meat cooking, and from $3.5{\times}{\times}10^6{\sharp}/cm^3$ to zeroth order in mackerel cooking respectively. When it comes to hood operation during cooking, the detected concentrations of generated aerosols are decreased as in taking flow rate of the hood increases. In cooking pork belly meat, the reduced amount of concentration is about $3{\times}10^6{\sharp}/cm^3$ compared to no hood operation, when hood in taking flow rate is $610m^3/hr$ In mackerel cooking, reduced concentration is $6{\times}10^5{\sharp}/cm^3$ in the same condition. Also, Naphthalene and Fluorene, which are known as polycyclic aromatic hydrocarbons (PAHs), are detected in the generated aerosols during cooking.

  • This study was conducted to assess meat quality and sensory properties of pork bellies from immunocastrated males (IC) compared to meat from surgically castrated males (SC), intact males (IM), and females (FE). Pork bellies from IC had significantly higher pH values than meat from either SC or FE. Pork bellies from IC showed lower CIE $L^*$ values than those from SC, but were redder (higher CIE $a^*$ values) than meat from SC or FE. However, no differences in visual color were observed between pork bellies from IC and SC pigs using National Pork Producer Council scales. Water holding capacity was higher in SC and FE than that in IC. IC showed no significant difference in cooking loss and shear force values compared with those of SC. Both SC and IC had improved fat content when compared to that in IM, and IC meat showed a similar fat content to that of FE. Pork bellies from IC showed higher ratings for all visual evaluation traits than those of SC and were the same as meat from FE. Boar odor was not significantly different among the treatments. IC was rated similar to SC for taste, tenderness, and overall acceptability.

  • This study was conducted to determine the meat quality characteristics of pork belly from 3 different two-way crossbreeds of Yorkshire${\times}$Landrace (YL), Yorkshire${\times}$Berkshire (YB), and Yorkshire${\times}$Chester White (YC), which were domesticated for Korean consumers. Twenty pigs from each crossbreed (total n=60) were randomly selected when they reached the 110-120 kg range of market weight, slaughtered, and cooled at $0^{\circ}C$ for 24 h. The pork bellies on the left side of the cooled carcasses were then sampled and analyzed. The pH of pork bellies was the lowest in YC among the crossbreds. There was no significant difference in fat content by crossbred, but YB bellies had the lowest moisture content (p<0.05). The cooking loss of YB bellies was lower than those of others (p<0.05). The TBARS values in YB was significantly higher than those of the others at 14 d. YL bellies had a higher percentage of stearic acid, oleic acid, and MUFA than the other breeds, while YB and YC had a higher percentage of myristic acid, linoleic acid, linolenic acid, and n-6 fatty acids than the YB (p<0.05). PUFA content and P/S were significantly higher in YC compared with YL. Except for arginine, the concentrations of most free amino acids were higher in YB bellies than in others, (p<0.05). Sensory evaluation scores of bellies were higher for YC than for other breeds (p<0.05).

  • The effects of dietary conjugated linoleic aicd on pork quality was investigated using sixty four pigs. CLA was synthesized by alkaline isomerization method with corn oil. Pigs were devided into 4 treatment groups(16 pigs/group) arid subjected to one of four treatment diets(0, 0.1, 0.2, and 0.3% CLA diets) for 2 weeks before slaughter. Pork loin and belly were collected from the animals(105∼110kg body weight) slaughtering at the commercial slaughter house. Pork loin and belly meat were aerobic packaged and then stored during 2. 5. 8. 11 and 13 days at 4$\^{C}$ refrigerator. Samples were analysed for meat color, texture and sensory characteristics. There were no diference in meat color(L*, a*, b*), texture and sensory property among control and CLA treatment (s), and no changes as the storage period passed. This results mean that feeding CLA to pork doesn't change the meat color and texture of the pork what consumers consider when they buy some meat. Especially, feeding CLA to pork didn't transform sensory property of the pork. We considered these result as no problem in the pig fed with CLA.
