To evaluate the microbiological quality of pork carcasses at different slaughtering process in large and small scale slaughtering houses, swabbing method was used to analyze microorganisms on the surface of pork belly in each process of before evisceration, after evisceration, before final wash, after final wash and in chilling. In autumn time, large scale slaughterhouse showed lower incidence of aerobic microorganisms (10²∼10³ CFU/㎠) than those of small scale slaughterhouse (10⁴∼10/sup 5/ CFU/㎠) during all processing lines. Samples from cold room of large scale slaughterhouse showed lower incidence of aerobic cells (10² CFU/㎠) than small scale slaughterhouse (10⁴ CFU/㎠). In winter and spring time, large scale slaughterhouse showed lower incidence of aerobic microorganisms than those of small scale slaughterhouse during the slaughtering process of before evisceration, after evisceration and before final wash, except spring samples from before final wash and chilling at cold room storage in spring time. After final wash, different sampling place of carcass such as belly, ham, jowl showed the different washing effect depending on the small and large scale slaughterhouse. After final wash, ham and belly had lower aerobic cell counts, but jowl had higher aerobic cell counts than each site before final wash.

The amino acid contents, physical and sensory properties for the loins of crossbred pigs (JJ90: live weight of 90∼100 kg; and JJ110: live weight of 110∼120 kg) and crossbred Jeju black pig (JB90: live weight of 90∼100 kg) were evaluated to investigate their quality. The total contents of structural amino acid, which were 18.15∼20.22% for all the samples without showing significant differences, included significant amount of glutamic acid, aspartic acid, lysine and leucine. The free amino acid content was 0.486% for JB90, which was greater than JJ90 and JJ110. Also, significant amount of taurine, serine, glycine, alanine, valine, and leucine could be observed in the free amino acid content of the samples. The redness (a/sup */) and yellowness (b/sup */) of JB90 were significantly higher titan those of JJ90 and JJ110. The water holding capacity, hardness, chewiness, juiciness and palatability of JJ110 and JB90 were higher than those of JJ90, but their difference was not significant.

The radio-sensitivity of pathogens and the effect of irradiation on microbiologican safety and mutagenicity of meat products such as seasoned and cooked beef and ham were investigated. Samples were radiation-sterilized and inoculated at 10/sup 7/ cfu/g with each of the four pathogens including Salmonella typhimurium, Escherichia coli, Staphylcoccus aureus, and Listeria ivanovii. No viable cells of pathogens were observed in the sample irradiated with 3 kGy. The D/sub 10/ value of inoculated pathogens in seasoned and cooked beef and ham were 0.24∼0.48 and 0.39∼0.45, respectively. Results of Ames test performed with non-irradiated and irradiated seasoned and cooked beef and ham were both negative at the level of 625, 1,250, 2,500, 50,000, and! 10,000 ㎍ sample/plate, respectively. Results indicate that low dose (2∼3 kGy) irradiation is effective to ensure safety for seasoned and cooked beef and ham with toxicological wholesomeness.

This study was conducted to evaluate the effects of Zizyphus vulgaris supplementation on growth performance, blood cortisol and meat quality characteristics in finishing pigs. The total of thirty-six [Duroc×Yorkshir×Landrace] pigs (91±2.11 kg average initial body weight) were used in a 30-days assay. Dietary treatments included 1) CON (basal diet), 2) T1 (basal diet for 15 days and 0.1 % Zizyphus vulgaris for 15 days) and 3) T2 (0.1 % Zizyphus vulgaris for 30 days). The ADG (Average daily gain), ADFI (Average daily feed intake) and ADG/ADFI during the feeding period were not significantly differences among the treatments (p>0.05). Backfat thickness of pigs fed CON was higher than those of T1 and T2 (p<0.05). The appearance rate of A or B carcass grade was in T1 (74%) and T2 (84%) was significantly higher than that in CON (58%) (p<0.05). Pigs fed Zizyphus vulgaris 0.1 % for 30 days tended to decrease on blood cortisol compared with pigs fed CON and T1. But, there was not significantly difference among the treatments (p>0.05). The Hunter's L/sup */ (lightness) value of loin in the pork fed CON was higher than that of loin in the pork fed T1 and T2 (p<0.05). After 7 days, the L/sup */ value of loin in the pigs fed T2 was higher increased than that of pigs fed T1 and CON (p<0.05). However, a/sup */ and b/sup */ values were not affected by dietary Zizyphus vulgaris (p>0.05). There were not found remarkable differences in sensory properties (marbling, firmness and color) among the treatments. The results from the present study suggest that Zizyphus vulgaris could be a effective feed additive to improve meat quality of pigs. However, further research is needed to investigate effects of carcass characteristics.

Leptin, the product of the obesity (ob) gene, is synthesized in adipocytes or fat cells and has been implicated in the regulation of food intake, energy balance and body composition in mammals. Therefore, the leptin gene could be a candidate gene controlling fat deposition, meat quality and carcass traits in cattle. In this study the microsatellite genotypes for leptin gene were determined and their effects on carcass traits and meat quality were estimated in Korean cattle. Six different microsatellite alleles within leptin gene were identified and gene frequencies of 173, 177, 184, 186, 190 and 192 bp alleles were 0.012, 0.308, 0.067, 0.260, 0.342 and 0.016, respectively. The microsatellite marker of the leptin gene showed a significant association with the carcass percentage (CP) and marbling score (MS). Animals with genotypes 192/192 and 177/184 had higher CP than animals with other genotypes. Animals with genotypes 184/192 and 177/184 had higher MS compared with animals with other genotypes. Thus, the results suggest that the 177, 184 and 192 bp alleles may be associated with increased carcass percentage and intramuscular fat levels. No associations were found between the microsatellite genotypes of the leptin gene and other carcass traits such as carcass weight (CW), backfat thickness (BF) and M. longissimus dorsi area (LDA). In conclusion, the microsatellite markers of the leptin gene may be useful for marker-assisted selection of carcass traits and meat quality in Korean cattle.

Korean Journal for Food Science of Animal Resources, volume 25, issue 1, 2005, Pages 32~38
Effects of supplemental charcoal powder and vitamin A on physico-chemical properties in 24 Hanwoo steers were investigated. The Hanwoo steers were randomly assigned to one of the three dietary treatments : 1) Control (commercial feed) 2) T1 (commercial feed supplemented with 2% charcoal powder and 0.2% vitamin A) 3) T2 (commercial feed with 2% charcoal powder). Crude fat content of proximate chemical composition in longissimus muscle was increased at control but moisture of control was rather lower than that of treatment groups (p<0.05). The WHC (water holding capacity) in longissimus muscle was tended to increase in control and shear force was higher in T2 (p<0.05). However, effects of diets charcoal power and vitamin A on pH were not found (p>0.05). Tenderness and flavor of sensory evaluation was improved significantly in control with peculiar and savory taste of Hanwoo being more emphasized. But Juiciness were not difference by treatments. When Hanwoo steers were fed with dietary charcoal powder and vitamin A, the palmitoleic acid and linoleic acid contents were higher compared with that of control (p<0.05), but oleic acid was higher in control than others.

Effects of persimmon peel powder on physico-chemical properties in 60 pigs was investigated. The pigs were randomly assigned to one of the four dietary treatments: 1) Control (commercial feed) 2) T1 (commercial feed supplemented with 1% persimmon peel powder) 3) T2 (commercial feed supplemented with 3% persimmon peel powder) 4) T3 (commercial feed supplemented with 5% persimmon peel powder). In proximate composition, moisture of pork from treatment groups were decreased by addition level increased than that of control but crude fat was increased (p<0.05). Crude protein and crude ash was no significantly difference. The total cholesterol, HDL-cholesterol and triglyceride of treatment groups was higher than that of control.. LDL-cholesterol of control was higher than that of treatment groups. The WHC (water holding capacity) of control was higher than treatment groups and shear value was higher in treatments group (p<0.05). pH was not significantly different between control and treatment groups. The hardness, juiciness and flavor of sensory evaluation were improved by treatments, especially in T3 (p<0.05). The meat color of treatment group showed whiter and redder than that of control owing to higher L/sup */, a/sup */ and b/sup */ value. In fatty acids, stearic acid contents of treatment groups were higher than that of control. The unsaturated fatty acid/saturated fatty acid ratio of the control, T1 T2 and T3 were 1.78, 1.71. 1.69 and 1.66, respectively and control had higher than the treatment groups. The hardness, juiciness and flavor of sensory evaluation were improved by treatments, especially in T3 (p<0.05).

This study was carried out to get the informations on microbes and protein extractability through comparing the quality attributes of Hanwoo fed in Korea, Hanwoo fed in Japan and Japanese Wagyu. The fresh beefs were stored at 4±l℃ for 13 days. In microbiological test, the total plate counts were higher in rump than in other beef portion as loin, chuck (p<0.000l). The number of psychrotrobes in the rump were maintained high levels (p>0.0001) for storage period, whereas the loin from Hanwoo fed in Korea, Hanwoo fed in Japan and Wagyu were lowest levels. The number of E. coli were no significantly different among the samples. In lactic acid bacteria, the loin form 3 grade Hanwoo (K3) had highest levels (p<0.0001). Comparing to the protein extractability, water soluble proteins were high in chuck (p<0.001). In the case of loin, water soluble proteins of K3 (3 grade Hanwoo) and Wagyu were high as 3.010 mg/g and 2.977 mg/g, respectively (p<0.001). Salt soluble protein of K1 (1 grade Hanwoo) was high as 7.437 mg/g (p<0.0001).

This study was performed to investigate physicochemical and textural characteristics, and antimicrobial effect for Listeria monocytogenes (LM) in low-fat functional sausages (LFFS) containing sodium lactate (SL) and potassium lactate (PL) during storage at 4℃ for 10 weeks. The LFFS treatments included CTL (Low-fat sausage control), TRT1 (SL 3.3%), TRT2 (SL 2.2% + PL 1.1%), TRT3 (SL 1.1% + PL 2.2%), TRT4 (PL 3.3%). Proximate composition for LFFS were 73.9∼75.2% moisture, 1∼2% fat and 15.5∼15.9% protein, and pH values ranged from 5.8 to 6.5. Expressible moisture (EM, %) and vacuum purge (VP, %) ranged from 22.9 to 33.0 and from 2.7 to 5.3, respectively. EM of CTL, TRT1 and TRT2 increased with increased storage time, however, no differences in VP were observed during storage time. Hunter color values (L, a, b) were not affected by the addition of SL and PL, and storage time (p>0.05). Most textural properties of LFFS were not affected by the addition of SL and PL, except for few cases, but those of CTL tended to increase with increased storage time. The addition of SL and PL into LFFS, alone or in combination, inhibited the microbial growth of inoculated LM during refrigerated storage, resulting in longer shelf-life than the control.

Antioxidant films are one active packaging technology that can extend food shelf-life through preventing lipid oxidation, stabilizing color, maintaining sensory properties and delaying microbial growth in foods. Because raw, fresh and minimal processed foods are more perishable during storage or under display conditions than further processed foods, they rapidly lose their original quality. Foods are susceptible to physical, chemical, and biochemical hazards to which packaging films can be effective barriers. Although films incorporated natural (tocopherols, flavonoids and phenolic acids) or synthetic antioxidants (BHT, BHA, TBHQ, propyl gallate) have been extensively tested to improve quality and safety of various foods, food applications require addressing issues such as physical properties, chemical action, cost, and legal approval. Increased interest in natural antioxidants as substitutes for synthetic antioxidants has triggered research on use of the new natural antioxidants in films and coatings. Use of new components (phytochemicals) as film additives can improve food quality and human health. The biosynthesis of plant phenolics can potentially be optimized by active coatings on harvested fruits and vegetables. These coatings can trigger the plants natural proline-linked pentose phosphate pathway to increase the phenolic contents and maintain overall plant tissue quality. This alternate metabolic pathway has been proposed by Dr. K. Shetty and is supported by numerous studies. A new generation of active food films will not only preserve the food, but increase food's nutritional quality by optimizing raw food biochemical production of phytochemicals.

This study was conducted to determine the effects of MgSO₄ supplement on meat quality and serum stress hormones concentrations in late finishing pigs. Sixty castrated Landrace pigs (average weight±S.D., 106.5±8.9 kg) were assigned to a control diet (without MgSO₄ supplement) and diet with MgSO₄(10 g/kg diet) supplemented. Pigs had free access to diets and water during five-day feeding period. At the end of feeding experiment, pigs were fasted for 16 hours and transported to commercial slaughter plant (30-minute transportation distance). After 2-hour lairage time, pigs were slaughtered, and blood samples were collected at bleeding procedure of slaughter. Pigs fed the diet with MgSO₄ supplement had higher (p<0.05) serum magnesium concentrations than those in pigs fed a control diet. Serum adrenaline, noradrenaline and cortisol concentrations determined at slaughter were not significantly different between dietary groups. Carcass temperature, pH at 24h post- slaughter, drip loss and color characteristics were not influenced (p>0.05) by short-term supplement of MgSO₄. Pigs fed the diet supplemented with MgSO₄ diet had lower PSE incidence (23.3%) compared to pigs fed the control diet (33%). These results indicate that short-term supplement of dietary MgSO₄ in late finishing pigs may not be beneficial in improving pork quality, and further study needs to assess feeding regime of magnesium supplement.

This study was carry out to investigate the quality characteristics of Korean native black ground pork compared with modern genotype ground pork during refrigerated storage. Korean native black pig and modern genotype pig were slaughtered at 75 kg and 105 kg of live weight, and for 240 days and 210 days of feeding periods, respectively. The ground lean pork (M. semimembranosus) was stored for 9 days at 4℃. The crude fat and crude protein contents were significantly (p<0.05) higher in Korean native black pork. The pH value after 5 days of storage was significantly (p<0.05) lower in Korean native black pork than in modern genotype pork. WHC of Korean native black pork was significantly (p<0.05) higher than that of modern genotype pork over time. The Korean native black pork maintained black reddish color because it had lower CIE L/sup */ value and higher CIE a/sup */ value than the modern genotype pork. CIE L/sup */, b/sup */, C/sup */ and h/sup O/ values decreased as storage time increased. TBARS (thiobarbituric acid reactive substance), POV (peroxide value) and FOX (ferrous oxidation xylenol orange) tended to increase as storage time increased in all of the groups, in particular, those values increased more rapidly in Korean native black pork. Total saturated fatty acid and stearic acid contents had significantly higher in Korean native black pork (p<0.05).

Purge & Trap method was applied to perform more simple and rapid detection for analysis of volatile flavor compounds in milk. Maximal sampling of 30 mL milk for glass flask sparger was treated by He gas purging for 2 hours. Reported major volatile compounds were detected by GC-MS after 2 hours absorption and desorbed from Purge & Trap equipped with Tenax trap. Volatile flavor compounds were analyzed by Purge & Trap and GC-MS to investigate the changes of flavor components in milk between raw and deodorized milk. Fourteen volatile compounds including acetaldehyde, ethanol, 2-propanone, dimethyl sulfide, isobutanal, 3-methyl 2-butanone, 2-butanone, 3-methyl butanal, pentanal, 3-hydroxy-2-butanone, methyl disulfide, hexanal, and 2 others were detected. Six compounds such as ethanol, dimethyl sulfide, pentanal, 3-hydroxy-2-butanone, and methyl disulfide were completely eliminated after deodorization treatment. Four compounds such as 3-methyl 2-butanone, 2-butanone, 3-methyl butanal, and an unknown compound 81 (M/sup +/) were also decreased after raw milk was deodorized. The other four compounds such as acetaldehyde, 2-propanone, hexanal, and an unknown compound (M/sup +/) were not decreased.

We investigated fermentation characteristics and the amount of exopolysaccharide (EPS) produced, and the correlation between EPS and rheological properties in stirred yogurt fermented with Streptococcus thermophilus St-Body 1. The changes of pH and lactic acid concentrations of yogurt showed different patterns according to fermentation temperatures. About 20 to 40% of lactose was utilized during 6 hrs incubation. The higher number of lactic acid bacteria was obtained at 31℃ incubation temperature rather than other incubation temperatures. The higher amount of EPS was produced at 12 hr or 24 hr rather than other incubation period at the same fermentation temperatures. The viscosity continuously increased during the fermentation period, however the syneresis of yogurt was shown the lowest value at 37℃ for 30 hrs incubation. In physical properties, the hardness and adhesiveness increased continuously with decreasing cohesiveness and elasticity as incubation process was extended. The stirred yogurt fermented with S. thermophilus St-Body 1 at 37℃ for 24 hr resulted in the highest score at each sensory evaluation category.

This study was carried out to determine the storage, cryotolerance, heat and drying resistance, when Lactobacillus acidophilus CT 01 isolated from preweaned piglet feces growing at suboptimal temperature. L. acidophilus CT 01 suboptimal temperature incubated for 48 hours had the slowest growth rate at 22℃ but the highest viable cell number after 36 hours at 22℃, with 1.3×10/sup 9/ CFU/mL. In case of 4 and 20℃ storage, the suboptimal temperature incubated groups had a viability higher than the control (p<0.01). The cryotolerance of suboptimal temperature incubated L. acidophilus CT 01 was a higher than the control (p<0.01). When L. acidophilus CT 01 was heat treated at 60℃ for 15 minutes and 30 minutes, the suboptimal temperature incubated L. acidophilus CT 01 at 22℃ had a viability higher more than the control (p<0.01). L. acidophilus CT 01 incubated suboptimal temperature was inoculated by 30% to the carrier, and dried at 50℃ for 12 hours had the highest viability in the suboptimal temperature incubated L. acidophilus CT 01 at 28℃.

Korean Journal for Food Science of Animal Resources, volume 25, issue 1, 2005, Pages 98~102
The purpose of this study was to demonstrate biochemical properties of lactoferrin (Lf) obtained from the colostrum of Korea native cow. The molecular weight of the purified Korean native cow's Lf (K-Lf) was 81kDa, the isoelectric point was 9, and the content of iron was 0.56 mg/g, which is indicated that iron saturation of the lactoferrin was 40.6%. Amino acid composition and a-helix content were different K-Lf from bovine Lf (B-Lf). Immunological cross reactivity was observed between K-Lf and B-Lf but not between K-Lf and human Lf (H-Lf) by immunodiffusion test and Western blot analysis. Out results indicate that structure of K-Lf is different from that of B-Lf although K-Lf and B-Lf were immunologically cross-reactive.

During the 1970s, concern arose that cured meats contained high levels of residual nitrite and preformed nitrosamines. Therefore, the search for alternatives and alternative approaches to the use of nitrite have been still continued, however no complete alternative for nitrite has yet been identified. Recently, it was publicized in Korea that nitrite-containing meat products would be detrimental to health, about which consumers have been seriously concerned. Therefore, this study was carried out to inform the consumer of the safety status of nitrite and thereby to lead proper consumption of meat products. For assessing the safety of nitrite, data regarding the regulation for use, metabolism in human body, and dietary intake amounts of nitrite were collected and analyzed. The mean intake level of nitrite for Korean per capita was recently reported to be not more than 1% of ADI set by JECFA. On the contrary, a calculation indicated that the daily nitrite intake per capita from saliva by ingestion of vegetables in Korea would be about 300-fold higher than that from cured meats. In consideration of the low consumption amount of meat products per capita of Korean, that is, at least one fifth, compared to European and American, there is no particular reason to concern about the impairment of health by nitrite intake from meat products for Korean. However, any effort for the reduction of residual nitrite content in cured meats should be given with an idea to minimize the intake of nitrite even from the minor source.
