Changes of pH, Meat Color, Cooking Loss, Shear Force and Sensory Evaluation on Hanwoo Meat Fed with Supplemental Fig Fermentation during Storage Period
Korean Journal for Food Science of Animal Resources, volume 22, issue 4, 2002, Pages 289~293
This study was conducted to investigate changes of pH, meat color, cooking loss, shear force and sensory evaluation on Hanwoo meat fed with supplemental fig fermentation(SFF) during storage period. A total of 10 Hanwoo bulls were subjected to one of two treatment diets (control and 10% SFF) from live weight of 400kg far 6 months. After slaughter, longissimus muscles were removed, zipper-wrapped and stored at 4
for 21 days. The pH, meat color, cooking loss, shear force and sensory evaluation of the samples were measured at 1, 3, 9, 15, 21 days of storage. There were no differences in pH, meat objective color(Hunter L, a and b) and cooking loss (%) of longissimus muscles between control and SFF treatment during storage. Shear force values of longissimus muscle from SFF treatment showed lower level in 1, 3 and 9 days and tended to decrease during storage. No differences in odor and appearance of sensory evaluation were observed between control and SFF treatment during storage. The taste induced by SFF was increased(f<0.05) at 1, 3 and 9 days of storage. These results indicate that the SFF may improve meat quality of Hanwoo during storage.
Nutritional Evaluation and Physico-Chemical Changes of Emulsified-Sausages Sold at Korean Markets during Storage at 1
Korean Journal for Food Science of Animal Resources, volume 22, issue 4, 2002, Pages 294~300
The physico-chemical properties of emulsified-sausages(wienner, frankfruter and boiled) were investigated during storage at 10
. Percentages of moisture, protein, fat, ash and carbohydrate in all treatments ranged 50.4∼53.4, 12.3∼16.0, 22.8∼26.5, 2.0∼2.9 and 6.5∼9.8%, respectively. Oleic, palmitic, linoleic and stearic acids were major fatty acids in various sausage samples. Glutamic and aspartic acids in these sausages were major. amino acids. In all treatments, sodium nitrite contents and organoleptic characteristics were decreased with increased storage time, while the mean values of volatile basic nitrogen(VBN), total bacterial count and thiobarbituric acid(TBA) were increased with increased storage time.
Identification of Korean Native Goat Meat using Amplified Fragment Length Polymorphism (AFLP) DNA Markers
Korean Journal for Food Science of Animal Resources, volume 22, issue 4, 2002, Pages 301~309
This study was carried out to develop the breed-specific DNA markers for breed identification of Korean native goat meat using amplified fragment length polymorphism (AFLP)-PCR techniques. The genomic DNAs of Korean native goat, imported black goat and four dairy goat breeds(Saanen, Alpine, Nubian and Toggenburg) were extracted from muscle tissues or blood. Genomic DNA was digested with a particular combination of two restriction enzymes with 4 base(Mse I and Taq I) and 6 base(EcoR I and Hind III) recognition sites, ligated to restriction specific adapters and amplified using the selective primer combinations. In AFLP profiles of polyacrylamide gels, the number of scorable bands produced per primer combination varied from 36 to 74, with an average of 55.5. A total of 555 bands were produced, 149(26.8%) bands of which were polymorphic. Among the ten primer combinations, two bands with 2.01 and 1.26 kb in M13/H13 primer and one band with 1.65 kb in E35/H14 primer were found to be breed-specific AFLP markers in Korean native goat when DNA bands were compared among the goat breeds. In the E35/H14 primer combination, 2.19, 2.03, 0.96 and 0.87 kb bands detected in imported black goat, 2.13 kb band in Saanen breed and 2.08 kb band in Nubian breed were observed as breed-specific bands showing differences between goat breeds, respectively. The E35/H14 primer combination produced four DNA bands distinguished between Korean native goat and Saanen breed. The is study suggested that the breed specific AFLP bands could be used as DNA markers for the identification of Korean native goat meat from imported black goat and dairy goat meats.
Effect of Feeding Mugwort Level on Pork Quality
Korean Journal for Food Science of Animal Resources, volume 22, issue 4, 2002, Pages 310~315
The effects of addition of mugwort pellet to feed pig on meat quality were investigated. Approximately 40 pigs were divided by 4 groups and different levels(0∼7%) of mugwort pellet were fed to each group up to 4 months. In the proximate composition, moisture contents were slightly higher in the T1(3%), and crude fat contents were lower (p<0.05) in the T1 and T2(5%) than any other. Hunter L and shear values in treatment group were higher than those of control, but pH was higher in the control. The tenderness and flavor of pork samples fed with mugwort pellet was higher than those of the control, when evaluated by trained sensory panels. The unsaturated fatty acid/saturated fatty acid(UFA/SFA) ratio of the control, T1, T2 and 73(7%) were 1.54, 1.65, 1.68 and 1.68. respectively(p<0.05), and treatment group had higher UFA/SFA ratio than the control.
Effect of Electron Benm Irradiation on the Oxidative and Microbiological Stability of Ground Pork during Storage
Korean Journal for Food Science of Animal Resources, volume 22, issue 4, 2002, Pages 316~321
Fresh ground pork was irradiated with the electron beam, and the microbiological and oxidative stability of ground pork was examined during refrigerated and frozen storage. During both storage, with the increase in the irradiation dose from 0 to 3.0 kGy, the inhibition effect of the growth of the total aerobic bacteria and the mesophiles also increased. Psychrotrophic bacteria were not detected at all in the whole experiment. On the other hand, electron beam irradiation promoted the oxidative rancidity of ground pork during refrigerated and frozen storage. The catalytic effect of oxidation was more pronounced with the electron beam dose of 3.0 than that of 1.5 kGy. As a result, the control of lipid oxidation must be achieved to fully utilize the sterilization effect of electron beam in the ground pork.

Ground pork was packaged(purged) with modified atmosphere (n
) and irradiated with the electron beam in order to find out whether modified atmosphere packaging (MAP) inhibit the microbial growth and lipid oxidation development caused by electron beam irradiation. After packaging and irradiation, ground pork was stored at 4
for 6 days and -15
for 3 months, and periodically the microbial counts and the thiobarbituric acid reactive substances (TBARS) for the determination of lipid oxidation were measured. The inhibition of growth of total aerobic bacteria and mesophiles was confirmed when the ground pork was irradiated with the electron beam dose of 1.5 and 3.0 kGy. The N
purging alone was also effective in reducing the development of lipid oxidation of ground pork during storage at 4 and -15
. The combination of electron beam irradiation(1.5 and 3.0 kGy) with MAP (N
) was effective to inhibit the growth of total aerobic bacteria and mesophiles, and retard the lipid oxidation of ground pork during storage at 4
for 6 days and -15
for 3 months.
Physico-Chemical and Sensory Properties of Emulsified Sausages containing Mulberry and Persimmon Leaf Powder
Korean Journal for Food Science of Animal Resources, volume 22, issue 4, 2002, Pages 330~336
The purpose of this study was to investigate the effects of mulberry and persimmon leaf powder with various contents(0.04%, 0.08%) on physico-chemical and sensory properties of emulsified-sausages. There were no differences(P>0.05) in moisture and crude ash contents(%), but crude fat contents(%) of the sausages containing 0.8% persimmon leaf powder showed the highest, compared to other treatments. pH values of all treatments decreased during storage period. Sausages containing mulberry and persimmon leaf powder had more bright and yellow, but less red color than the control. Hardness values of the sausages containing 0.04% mulberry and persimmon leaf powder were higher than those of a control and other treatments. The addition of mulberry leaf powder had better flavor and overall palatability of sausages than persimmon leaf powder. However, no differences in color, flavor, tenderness and overall palatability were observed on 60 days of storage. These results indicated that the addition of mulberry and persimmon leaf powder for the manufactured of emulsified-sausages partially affected physico-chemical and sensory properties. Further research will be performed why the addition of these powders affect the product quality.
Feeding Effect of Ginseng by-product on Characteristics of Pork Carcass and Meat Quality
Korean Journal for Food Science of Animal Resources, volume 22, issue 4, 2002, Pages 337~342
This study was carried out to investigate the feeding effect of by-products such as ginseng loaves(GL) and stem (GS) which had about 8% of crude saponin on pork carcass and meat quality characteristics when they were fed for 40 days. The ginseng leaves and stem were added in feed and the pigs were slaughtered at 10, 20, 30 and 40 days. The chilled carcass weight and trimmed fat contents were higher(86.50 kg) in the pork fed for 40 days. The yields of fore legs were higher in pork fed for 10 days(P<0.05) and there was no different in the yields of the other portion cuts such as shoulder, rib, loin, belly, hind legs and tenderlons. The incidence of percentages for grade A and B decreased as the feeding periods increased up to 40 days. The backfat thickness was lowest in carcasses from pigs fed up to 20 days(P<0.05). The L values were highest in pork fed up to 30 days(50.22) and lowest(46.91) for pork fed 10 days. The incidence of PSE pork was low in pork fed for 20 days when compared to other feeding days. Cooking loss was lowest and water holding capacity(WHC) was highest in pork fed GL and GS stem, respectively. However, the analysis for accumulation contents of saponin and functionality in pork fed GL and GS is needed in the future research.

Korean Journal for Food Science of Animal Resources, volume 22, issue 4, 2002, Pages 348~351
This study was carried out to investigate the anticancer effect of extracts from sulfur fed duck carcass. Growth inhibition of cancer cell lines was measured by MTT assay. Eleven cancer cell lines, such as Calu-3(human lung carcinoma), SK-MES-1(human lung carcinoma), HL6O(human leukemia), KB(human epidermoid of mouth carcinoma), Farrow(human melanoma), HEP-2(human larynx carcinoma), SNU-1(human stomach carcinoma), K-562 (human leukemia), WiDr(human colon carcinoma), P388(mouse leukemia) and 3LL(mouse lung carcinoma) showed the growth inhibition higher than 50%, but those, such as SF-188(human brain carcinoma), A-549(human lung carcinoma) and HEC-lB(human uterus carcinoma) showed the growth inhibition lower than 50% in the extract of sulfur fed duck carcass at the concentration of 10 mg/㎖. The sulfur fed duck carcass extract had better growth inhibition than the normal counterpart against various cancer cell lines at the concentration of 10 mg/㎖. When the effect of growth inhibition of an effluent by different concentrations of methyl alcohol(25, 50, 75 and 100%) tested on Diaion HP-20 column chromatography, an effluent by concentration of 100% methyl alcohol showed the most strong effect of growth inhibition against HEP-2(human larynx carcinoma).
Antimutagenic Effects of Extracts of Curry Powder and Its Individual Spice
Korean Journal for Food Science of Animal Resources, volume 22, issue 4, 2002, Pages 352~357
Antimutagenic effects of extracts from curry powder and its individual fourteen kinds of spices, were investigated by Ames test. The antimutagenic effects against a direct mutagen, 2-nitrofluorene(2 -NF) and two indirect mutagens, 2-anthramine(2-AT) and 2-acetamidofluorene (2-AE) in the S. typhimurium TA98 were tested. For the 2-NF, the antimutagenicity of cinnamon, fenugreek, fennel, ginger, clove, turmeric and celery seed were determined as 42, 38, 32, 28, 24, 23 and 20%, respectively. The antimutagenicity of clove against the 2-AT was the highest (116%), and followed by the order of celery seed(103%), cardamon(100%), red pepper(99%), cinnamon(92%), cumin(83%), ginger(82%), fennel(82%), coriander (71%), nutmeg(68%) and turmeric (55%). The results also showed that the antimutagenic effect of clove against the 2-AF was superior to other spices. In case of curry powder among more than 10 kinds of spices, the antimutagenenicity against the 2-AT and 2-AF showed 23% and 6%, respectively, but no effect was observed against the 2-NF.
Comparison of Physico-Chemical, Sensory and Nutritional Characteristics for Water Extract from Bull's Bones of Different Breed
Korean Journal for Food Science of Animal Resources, volume 22, issue 4, 2002, Pages 358~362
The physico-chemical, sensory and nutritional properties of water extract from bull's bones of Hanwoo, Holstein, and imported breed were investigated to provide scientific information for consumers. The turbidity, viscosity, lightness(L value) and sensory scores were highest for water extract from Hanwoo's bones among three breeds(p<0.05). Total nitrogen and calcium contents, and calories were higher for water extract from the bones of Hanwoo and Holstein than the imported one(p<0.05), but no differences in the water extract were observed between Hanwoo and Holstein. In amino acid compositions, the percentages of methionine were the highest for water extract from Hanwoo's bones. These results indicated that the water extract from the bones of Hanwoo had the most acceptable quality among three breeds.
Manufacture and Evaluation of Low-Eat Meat Products(A review)
Korean Journal for Food Science of Animal Resources, volume 22, issue 4, 2002, Pages 363~372
Reducing the fat content of processed meat products can be performed by (1) using leaner raw meat materials (2) inducing non-meat ingredients that serve to replace a portion or all of the fat, and (3) applying new ingredient combinations, technologies or processing procedures that decrease the fat and cholesterol content of meat products. Low-fat meat products were manufactured with Int replacers which were food ingredients that had the functional and sensory properties of fat without contributing fat calories, resulting in lower fat(<3%) content. Added water, non-meat proteins, carbohydrates, such as starch and hydrocolloids(gums) and vegetable oils have been used as typical fat replacers to be used in meat products. In addition, fat substitutes included structural lipids, sucrose polyester and ingredient combinations. Formulations for the manufacture of low-fat meat products in combined with new technologies have focused on the use of fat replacer combinations that contributes a minimum of calories and not detrimental to flavor, juiciness, mouthfeel or textural traits expected more traditional products. In conclusion, some combinations of fat replacements that mimics the flavor, mouthfeel and textural characteristics of fat offer potential for further development of low-fat meat products to have similar characteristics of regular-fat counterparts.
