This study was performed to investigate the effect of pork on the cadmium detoxification in rats. Ninety male Sprague-Dawley strains were divided into five stoups based on cadmium treatment(0, 25, 50, 100, 250 ppm) and cadmium intoxication was observed for 8 weeks. During following 8 weeks, casein was replaced by Pork and the effect of pork was compared with casein. During intoxicating, the growth mte was lessened. Feed efficiency ratio was significantly low, as cadmium intake was high Discontinuing cadmium feeding, the body weights were relieve4 Pork-fed groups seemed to have higher body weight than casein-fed groups. During intoxication, hemoglobin and hematocrit were dependent upon cadmium intake. However, they became normal at detocification stage. Cadmium accumulation of the pour-fed group was lower than that of casein. Especially, the factors which affected the cadmium content in kidney were Cd(p<0.001) and $Cd^*pork(p<0.001)$. Metallothionein(MT) was increased with cadmium, and MT was not likely to be affected by pork. This study may provide scientific background of pork for detoxification from heavy metals such as cadmium.

To evaluate the effect of irradiation on restructured pork jerky containing paprika and Japanese apricot extracts, the quality of protein was determined in vitro based on the formation of trypsin indigestible substrate inhibitor (TIS) and the computed protein efficiency ratio (C-PER) as determined based on the protein digestibility and amino acid analysis. In addition, we compared the effects of electron beam irradiation to those of gamma irradiation. Approximately 3% of the moisture content of pork jerky was reduced in response to irradiation with 3kGy administered using an electron beam however, no additional reduction was observed in samples that were subjected to higher doses of irradiation. In addition, there were no notable differences in the crude protein and fat content of pork jerky samples that were subjected to irradiation, regardless of dose. Furthermore, the total amino acids profiles did not change in response to electron beam irradiation. However, the in vitro protein digestibility increased by 7% in response to 3kGy of electron beam irradiation and 5kGy of gamma irradiation, but no significant changes in digestibility were not observed in response to treatment with higher doses. TIS quantified as trypsin inhibitors were formed in response to irradiation using the electron beam (3kGy) and gamma rays (5kGy), although there was a slight reduction in the production of TIS inhibitors in samples irradiated with higher doses. Moreover, only samples irradiated with 10kGy (electron beam and gamma ray) showed higher TBA values than those of the control samples. Finally, the C-PERs $(2.50{\sim}2.60)$ were greater in all of the irradiated pork jerky samples than in the control samples (2.22). Taken together, these results suggest that electron beam irradiation and the incorporation of extracts (paprika and Japanese apricot) may be useful methods of improving the nutritional quality of pork jerky.

The purpose of the current study was to examine the influence of different maternal nutrition treatments during pregnancy on body weight, muscle fiber number, carcass traits, and pork quality traits of offspring. A total of 18 crossbred sows (Landrace${\times}$Yorkshire${\times}$Duroc) were randomly assigned to one of three nutritional treatment groups; control, high energy, and high protein. The control group was fed a standard diet, the high energy group was fed a diet that contained 30% increased metabolizable energy, and the high protein group was fed a diet that contained 30% increased limiting amino acids compared to the control. The sows in each group were fed equal quantities of each diet (1.9 kg/d) for the entire gestational period. A total of 36 piglets from each sow were used to evaluate changes in body weight, muscle fiber number in the longissimus dorsi muscle at birth, carcass traits, and pork quality traits. Birth weight of offspring born to sows in the high energy diet group was significantly higher compared to the high protein diet group (p<0.05). However, body weight of offspring after birth was not significantly different between the groups. Muscle fiber number for the longissimus dorsi muscle at birth was not significantly different between the groups. In addition, there were no significant differences in carcass traits or pork quality traits between offspring born to sows in the control group and those born to sows that received high energy or high protein diets during pregnancy. Based on these results, it appears that maternal nutrition treatment during pregnancy, regardless of whether it is with high energy or high protein diets, does not have a significant effect on body weight, muscle fiber number at birth, carcass traits, or pork quality traits.

Changes in the physicochemical properties of frying oil after single or repeated use in foodservice establishments were studied. The experiment was designed to simulate the practical frying practice based on a survey from the dieticians in the food service establishments. Used oils came from the single frying of mackerel and the sequential frying of 1) potato and mackerel, 2) battered pork and mackerel, and 3) potato, battered pork, and mackerel. The used oil samples were analyzed and compared with the fresh one. Oil quality parameters such as acid value, peroxide value, thiobarbituric acid value, iodine value, viscosity, and color were measured at each step of deep-fat frying. The physicochemical properties of the frying oils have been more or less affected by the frying conditions. However, the used oils resulted from the experimental trials were within the range of acceptance as indicated by the acid and peroxide values.

The objective of this study was to address the issues associated with the solubility of the pork meat oligopeptide, while maintaining its original nutritional value and improving its digestibility. The pork meat oligopeptide was used to produce an oral liquid supplement that was contained in a 200 $m{\ell}$ can. The formulation was designed to satisfy 20% of the daily recommended nutrition intake of an adult male aged between 20 and 29. Analysis of the quality characteristics showed that this formulation was highly homogenized as an oral liquid supplement with advanced solubility. In addition, based on the viscosity, pH, color value, turbidity, and brix, the product was shown to advanced processing quality with great solubility; however, there was some concern that the taste would be deteriorated due to the bitter taste of the peptide. Thus, further studies need to be performed before this formulation can be commercialized.

The objective of this study was to investigate the effects of sodium alginate (SA) and pressurization levels on pH, water-binding and textural properties of pork muscle gels (PMG) containing salt. Ground lean pork with 1.0% NaCl and a given amount of SA (0.25, 0.5, 0.75 and 1.0%, respectively), was pressurized to 100, 200 or 300 MPa and subsequently gelled by heating. Results showed that addition of SA into pork muscle enhanced water-holding capacity (WHC) of PMG (p<0.05) as SA increased from 0.25% to 1.0%, with pH slightly increased (p>0.05). A decrease (p<0.05) was observed in all textural parameters (hardness, cohesiveness, springiness and chewiness). Pressurization had no effect on the tendency of WHC to increase or the decrease of the textural parameters. However, the effectiveness of pressurization to enhance textural properties of PMG was significant at some SA levels, especially ${\geq}200MPa$ and at ${\leq}0.75%$ SA levels. Different combinations of pressure and SA levels could bring about variation in textural properties of PMG while SA enhanced WHC of pork muscle. The multiformity of the texture will open up a wide range of technological possibilities for the manufacture of pork-based restructured low-fat products.

Purpose: This study analyzed the dietary patterns of Central Asian immigrant workers (Mongolia, Kazakhstan, Uzbekistan, and Kyrgyzstan) living in South Korea to determine the food acculturation and how their dietary practices have changed after immigration. Methods: Self-administered questionnaires were completed by 186 Central Asian immigrant workers living in South Korea. A food frequency questionnaire (FFQ) was used to obtain information on the consumption frequency of 22 food items before and after their immigration to Korea. Results: Central Asians switched to Korean meat consumption patterns, which consume mainly pork, chicken, and beef, showing a decrease in the intake of beef and lamb and an increase in that of pork. Their consumption of Namul (cooked vegetable), Kimchi, rice, and marine products increased while that of potatoes decreased during acculturation to Korean food culture. Positive changes were observed in Mongolians' eating habits. Their meat-based diet turned into a healthy one in which nutritional balance was achieved by consuming the various food groups. Negative dietary changes were also observed; intake of instant foods and coffee increased while black and green tea consumption decreased. Intake of Namul (p < 0.01), Kimchi (p < 0.01), rice (p < 0.001), ramen (p < 0.001), pork, chicken (p < 0.01), fish (p < 0.01), seafood (p < 0.001), and coffee (p < 0.001) increased significantly in the group that responded and their health improved after moving to Korea. This result suggests that health improved among those who were well settled in Korea and ate the various food groups. Conclusion: These findings can help understand the acculturation process to Korean food culture and provide a basis for developing policies to help them adjust to Korean food culture.

Objectives of this study were to investigate the acceptability of liver sausages, one of the most favorite product of meats, and to examine the applicability of pork liver in manufacturing sausages. Sausages containing different proportions of pork liver were manufactured with various processes and were tested and analysed by means of sensory evaluation. Based on th basic recipe for manufacturing sausages, fifteen recipies were proposed with different combinations of ingredients, followed by evaluations on their physicochemical and nutritional properties. Sausages manufactured with different methods (sliceable, spreadable, smoked spreadable) and different proportions of liver were also evaluated. The Findings from these experiments are summarized as follows: 1. As the percentage of the liver was increased, outer color of experimental sausages were significantly decreased. 2. The hardness, gumminess, chewiness were significantly decreased as the amount of liver increased. 3. Sausages containing 30% pork liver had best acceptability after swallowing. 4. The flavor and taste of liver in experimental sausages were significantly increased by adding liver. In summary, sausages containing 30% pork liver had best acceptability for consumption in terms of the indices measured in this study.
