  • Studies were performed to 1) investigate if ferric iron bound in complex with iron-solubilizing meat components is absorbable, 2) compare the relative iron-solubilizing capaicty of meats, and 3) investigate the physicochemical and compositional characteristics if meat meat has iron-solubilizing components . Iron-solubilizing components of beef were isolate from pH 2 HCL homogenates into dialysis bags(MWCO of 6-8K). Radiolabelled iron complexes were then generated using ferric iron and the isolated low-molecular-weight components(ILC) from undigested beef or ascrobate. The bioavailabilities of radioiron in these complexes or as ferric iron were measured as radioiron absorption into the blood one hour after injection into ligated duodenal lops of rats. Iron absorptions were ferrous -ascorbate complexes(18.8$\pm$2.2%)> ferric-ILC complexes(4.9$\pm$0.6%)>ferric iron (23.2$\pm$0.3%)(p<0.05). ILC from 0.1g of beef, pork, chicken, fish , or egg white were added to 400$\mu$g ferric iron in pH 2 HCL, the pH raised to 7,2, and soluble iron determined in the supernatant after centrifugation at 2,500g for 10 min. Iron solubilizing capabilities of ILC were pork (99.9$\pm$0.1%)>beef(93.6$\pm$3.5%)> chicken (75.8$\pm$1.8%) > fish(64.6%$\pm$3.6%)>egg white(50.9$\pm$0.9%)(p<0.05). The compositional and physico-chemical characteristics of the ILC from the above dietary protein sources were investigated.

  • Before Jin (秦) period, Oriental (Eastern) culture was established in Korea different from China. Bulgogi (babecued beef, 貊炙) and legume fermented soy were transmitted into China. Afterward, alcohol drink, rice cake and cookie, shic-hae (lactic acid fermented fish products), Kimchi (fermented vegetable) were introduced and modified for Korea. Buddhism was transmitted to Korea through China, but selective animal was used as food. Later period of Koryo Dynasty, meat-eating become common due to mongorian influence and distilled spirits was introduced by mongorian. During Chosun Dynasty, table setting of spoon and chopstick was established, due to Confucian influence, dog eating, raw fish and raw meat eating became popular and nutrition for elderly was developed, whereas tea culture declined. In recent period (under the Japanese rule) Chinese introduced chinese noodle, chinese cuisine, chinese pancake and sun-dried salt. many chinese cultivated chinese vegetables.

  • Effects of four kinds of phosphate complex on the water holding capacity (W.H.C) and protein solubility of yellow-corvenia (Pseudosciance manchurica) and hair tail (Tichurus lepturus) meat paste were investigated. The formulations of four kinds of phosphate complex employed to this experiment were made by mixing several phosphates such as sodium polyphosphate, sodium pyro-phosphate, sodium acid pyro-phosphate, potassium pyro-phosphate, sodium tetra meta-phosphate, sodium ultra meta-phosphate and sodium hexa meta-phosphate, and monoglyceride at different mixture ratios. Among the four kinds of phosphate complex, phosphate B complex which was formulated by mixing sodium poly-phosphate 50%, sodium pyrophosphate 20%, sodium tetra meta-phosphate 20%, sodium acid pyrophosphate 5% and sodium ultra meta-phosphate 5% was most effective on enhancing the W.H.C and protein solubility of yellow corvenia meat paste, and in case of hair tail meat paste, phosphate C complex which was formulated by mining sodium poly-phosphate 40%, sodium pyro-phosphate 30%, potassium pyro-phosphate 15%, sodium tetra meta-phosphate 10%, and sodium hexa meta-phosphate 5% was more effective than other phosphate complex, and their optimum addition level was 0.4% respectively in weight of fish meat paste. Texture characteristics such as hardness, cohesiveness, and springiness value of Kamaboko (fish meat paste product) were evaluated as best when 0.3% of phosphate B complex was added. The optimum cooking condition of Kamaboko to get good texture was heating for 45 mimutes at $85^{\circ}C$.

  • The sacrificial foods using at 88 villages in Andong area where the village sacrificial rituals are performed, were investigated in 1994. The finding are as follows; 1. Since the village sacrificial rituals keep ancientry, white Baeksulki without any ingredients is used as Ddock (a steamed rice cake) in 74 villages, and in 5 villages the Baeksulki was served just in Siru (a tool used to prepare Ddock). The type of meat serving in rituals has been changing from large animal to small animal and the type of light from bowl-light to candle. 2. Though the ritual observes Confucianism style, memorial address was offered in 34 villages and only in 8 villages, liquor was served 3 times and the address was offered. In 60 villages, liquor was served only once, and calling village god, bowing twice, and burning memorial address paper were performed in order. Burning paper has been meaningful in rituals. 3. Tang (a stew) was served in 21 villages, and in 18 villages even Gook (a soup) was not used. The numbers of village which do not use cooked rice and Ddock are 14, respectively. 4. Fruits are essential in rituals foods. In 63 villages, 3 kinds of fruits are served and this is contrasted with even number of fruits in Bul-Chun-Wi Rituals. 5. In 25 villages, fish and meat are not served. As meat, chicken in 19 village are served. Meat Sikhae (a fermented rice beverage) prepared with meats or fish are served in 5 villages. Slice of dried meat is served in 73 villages commonly. 6. In gender of god for village shrine, woman in 43 villages, couple in 17 villages, man in 9 villages, mountain god in 2 villages, villages tree, etc were enshrined. In 52 villages liquor is served in rituals (liquor is used in 58 villages including serving god), in 28 villages sweet liquor (Gamju) is served for god (sweet liquor is used in 46 villages), and liquor, water, or sweet liquor is just displayed on table but not served in 8 villages. Incensing is found to be not common in village ritual, only in two villages it is performed. The most appropriate rituals food is thought to be pig for mountain god. Home dishes can not be used in village ritual and spoon is not used and chopstick is prepared from wild plant. Meat and fish are used in the raw.

  • In this study, the alkiline water washing condition of mackerel(Scomber japonicus) dark meat was investigated to improve processing conditions of red muscle fish meat paste heating gel. Chemical alkaline water(CWM) and electrolytic alkiline water(EWM, pH 12) were used for washing the mackerel raw meat. Washed meats were minced with 2.5% salt and heated at $90^{\circ}C$/15 min to testing texture profile analysis. Moisture of CWM and EWM was increased with both washing times(p<0.05). Crude lipids and protiens were decreased with washing times. Lightness of chemical alkaline water washed mackerel heated paste gel(CWHPG) was higher than electrolytic alkaline water washed mackerel heated paste gel(EWHPG). Redness and yellowness were more decreased than control meats. Jelly strength of CWHPG and EWHPG was not increased more than 2 times wased meat and was increased with protein decrease. Texture profile analysis, max force1 of CWHPG and EWHPG was higher hardeness than the control meat except gel strains. From these results, it could be suggested that electric alkialine water washing is also effective in advance the red meat paste heating gel process of kamaboko industry.

  • This study investigated the effects of a healthy image on the preference and intake frequency of meat and animal products. The study looked into beef, pork, chicken, sausage, mackerel, cutlass fish, croaker, tuna, squid, shrimp, clams, fish cakes, eggs, milk, yogurt, ice cream, and cheese. A total of 359 usable surveys given to elementary school students, college students, and adults were collected using a convenient sampling method. While milk had the healthiest image, sausage had the least healthy image. The respondents preferred yogurt the most and sausage the least. The intake frequency of eggs was the highest and clams the lowest. The healthy image, preference, and intake frequency for all studied foods showed significant differences across both gender and age. The relationship between healthy image and preference was significant for all foods, and a healthy image always had a positive influence on preference. The relationship of healthy image and intake frequency was significant in 14 foods except for mackerel, cutlass fish, and tuna. Also a healthy image created a positive effect on the intake frequency of 14 foods.

  • To clarify the factors influencing the physical properties of fish after heat treatments, we investigated changes in the properties of proteins in the dorsal ordinary and dark muscle of yellowtail (Seriola quinqueradiata) heated under different conditions commonly used for the purposes of food hygiene. High-temperature/short-time heating (85℃ for 90 s and 75℃ for 60 s) affected the protein solubility more than low-temperature/long-time heating (63℃ for 30 min). Sodium dodecyl sulphate-polyacrylamide gel electrophoresis and differential scanning calorimetry showed that low-temperature/long-time heating reduced the degree of actin denaturation in fish compared with that by other heating conditions. In addition, collagen solubility was enhanced with low-temperature/long-time heating. Therefore, these results suggest that differences in the degree of actin and collagen denaturation are responsible for the enhanced meat tenderness and diminished meat shrinkage, resulting from low-temperature/long-time heating.

  • This study was compared the effect of shelf-life and DHA accumulation in chicken meat from broilers fed experimental diets for two weeks($21{\sim}35$ days) of growers. Two hundred-ten male Ross broilers, 1 day of age, were randomly allocated to seven treatment groups. Experimental diets were assigned to each of the seven groups: control diet containing tallow, T1 with 1.00% fish oil, T2 with 2.00% fish oil, T3 with 2.00% fish oil, 200 ppm vitamin E and 200 ppm vitamin C, T4 with 2.00% fish oil and 200 ppm vitamin C, T5 with 2.00% fish oil and 200 ppm vitamin E, and T6 with 3.00% fish oil. The levels of DHA in chicken meat was the highest in T6, and T1 in breast muscle and thigh muscle with skin was higher than that of $T2{\sim}T5,\;T2{\sim}T5$ in raw chicken meat and wing with skin was about two-fold higher than that of T1. The contents of DHA in chicken meat according to storage days were significantly reduced to 42.30%, 49.38% and 48.51% in T1, T2 and T6, respectively, and this decrease was higher than that of T3, T4 and T5 (p<0.05). Particularly, the rate of reduction of DHA was the lowest in the T3 and T5, which were the lowest in TBARS(thiobarbituric acid reactive substances). TBARS increased in the order of T6, T2 and T1, but reduced in the order of T3, T5 and T4 according to storage days, and there was a significant difference among the treatment groups (p<0.05).

  • The effect of additional amounts of subsidiary materials on texture of fish meat paste were examined using Instron Universal Testing Machine to obtain fundamental data for steamed Alaska pollack meat paste showing good quality. The hardness revealed the good correlation with jelly strength among the six kinds of parameters of Instron texturometer. Products with higher hardness showed a better quality, but those with hardness higher than 16kg showed decreasing quality with increasing hardness. Predicting the quality of steamed Alaska pollack meat paste with various additional amounts of subsidiary materials as a function of hardness, H, the equation could be deduced as follows: H=11.56+0.54Xcs, H=12.22-0.23Xsp and H=11.65-7.13Xpp. The reasonable equations for predicting the quality of steamed Alaska pollack meat paste with various additional amounts of mixed subsidiary materials could be summarized as follows: H=11.57+0.53Xcs+0.44Xsp, H=11.97-1.83Xpp-0.17Xcs, and H=11.58+0.08Xpp-0.23Xsp.
