This study was conducted to identify sensory characteristics of soy-meat samples by trained panels and to observe the relationship between these sensory characteristics and consumer acceptability of the samples. Descriptive analysis was performed on eight samples; four types of patty style soy-meat samples (Soy-meat Patty; SP) made with a Ddukgalbi recipe (YSP, VSP, LSP, and SSP) and four types of Bulgogi style soy-meat samples (Soy-meat Bulgogi; SB) made with a Bulgogi recipe (YSB, VSB, LSB, and SSB). Seven panelists were trained, and they evaluated the appearance, odor/aroma, flavor/taste, texture/mouth feel, and after taste attributes of these samples. Forty attributes were generated by panelists, and 37 attributes were significantly different across products (p<0.05). The SB group was characterized by beef, leek, and garlic flavor as well a sweetness, denseness, slipperiness, chewiness, and pepper after taste. The SP group was characterized by roughness, particle size, rancid oil flavor, raw bean flavor, astringent, sourness, and adhesiveness. Consumer test (n=125) showed that the VSB sample had the highest scores for acceptability of appearance, flavor, texture, and overall liking. The PLSR results show that the attributes that were more positively associated with acceptance of soy-meat samples were beef taste, wetness, and chewiness, whereas the raw bean smell and rancid oil flavor attributes were negative.

The definition of meat analog refers to the replacement of the main ingredient with other than meat. It also called a meat substitute, meat alternatives, fake or mock meat, and imitation meat. The increased importance of meat analog in the current trend is due to the health awareness among consumers in their diet and for a better future environment. The factors that lead to this shift is due to low fat and calorie foods intake, flexitarians, animal disease, natural resources depletion, and to reduce greenhouse gas emission. Currently, available marketed meat analog products are plant-based meat in which the quality (i.e., texture and taste) are similar to the conventional meat. The ingredients used are mainly soy proteins with novel ingredients added, such as mycoprotein and soy leghemoglobin. However, plant-based meat is sold primarily in Western countries. Asian countries also will become a potential market in the near future due to growing interest in this product. With the current advance technology, lab-grown meat with no livestock raising or known as cultured meat will be expected to boost the food market in the future. Also, insect-based products will be promising to be the next protein resource for human food. Nevertheless, other than acceptability, cost-effective, reliable production, and consistent quality towards those products, product safety is the top priority. Therefore, the regulatory frameworks need to be developed alongside.

The purpose of this study was to survey the various kinds of cooked beef products focusing on 'Chim' (a steamed beef products) through historical literatures written from 1670 to 1945 in korea. 'Chim' was recorded 25 times in the references and could be classified to 5 groups based on major ingredients such as stomach, intestine, lean meat, tail and ribs. Among the eleven cooked products of 'Chim', 'Kalbi-chim' (a steamed ribs) was recorded most frequently and 'Sundae-chim' (sausage-like product) was the next. Though 'Kalbi-chim' has been used untill present day but 'Sundae-chim' was disappeared in the early 19th centuries. Ribs were most popular ingredient among the major ingredients such as stomach, intestines, lean meat, tail, feet and ribs. Twenty one kinds of subingredients including pheasant meat, blood clot and flour were used for 'Chim'. Decorating ingredients such as roasted sesame power, pine nut and thin-layer fried eggs and seasonings such as pepper, roasted sesame powder, tripe, garlic, soy sauce and seasonings such as pepper, roasted sesame powder, tripe, garlic, soy sauce and sesame oil were used for 'Chim'.

The objective of this study was to investigate the effects of supercritical carbon dioxide (SC-$CO_2$) treatment on meat quality and sensory evaluation of marinated pork. Meat marinated in two traditional Korean marinades, soy sauce and hot-pepper paste, and raw marinated meat were then treated with 7.4, 12.2, or 15.2 MPa $CO_2$ at $31.1^{\circ}C$for 10 min. The SC-$CO_2$ treatments had no effect on the meat pH (p>0.05) or Warner-Bratzler shear force (p>0.05). There was no significant difference (p>0.05) in the total loss (sum of treatment loss and cooking loss) between the control and SC-$CO_2$ treated samples at 15.2 MPa (soy sauce marinated pork: 21.78 vs. 18.97%; hot-pepper marinated pork: 21.61 vs. 18.01%). After the SC-$CO_2$ treatment, lighter surface colors were observed in the treatment samples compared to those of the control samples (p< 0.001). However, tasting panelists were unable to distinguish a difference in color or in overall acceptability of the control and treatment (p>0.05). In the case of soy sauce marinated pork, when SC-$CO_2$ applied at 15.2 MPa and $31.1^{\circ}C$for 10 min, treatment samples showed a tenderer meat than the control samples. Therefore, the SC-$CO_2$ treatment conditions had no adverse effects on the sensory quality characteristics of the marinated meat products.

Blends of pork meat (20%), defatted soy flour (25%), and corn starch (48.61~53.71%) were prepared with or without additional non-meat ingredients, i.e., onion powder (1%), alone or in combination with carrot powder (1.5%) or extract (1.5%), or defatted oat flour (5%). All blends were formulated for 22.78% moisture, with water added where necessary. They were extruded using a laboratory single-screw extruder at 16$0^{\circ}C$ profess temperature and 170 rpm screw speed. The additional ingredients generally decreased product expansion and increased bulk density and shear force. When the product with no additional ingredient and the product with onion powder were evaluated by trained sensory panelists, \"grain complex\" was the most intense flavor note for both. With 1 % onion powder in feed, a distinct \"onion\" flavor note was detectable in extrudates. All the products may be considered \"healthful\" based on nutrient profiles.t; based on nutrient profiles.

Chicken beef pork meats and isolated soy protein (ISP) were heated at 10$0^{\circ}C$ for 30min and then heat-resistant proteins were fractionated to examine cross-resistant protein from chicken meat but not with beef pork or ISP. Dot blotting using the polyclonal antibody showed that the sen-sitivity for detecting chicken meat was 1$\mu$m and antibody-antigen reaction was dose-dependant. Results of dot blotting analysis to compare the amount of chicken meat present in arket meat products(Kentucky Frank sausage;chicken meat 46.52% and pork 24.92% vs Bulgogi Ham;chicken meat 28.89% and turkey 31.44%)showed that the significant differences between two meat products in terms of chicken meat concentrations. Dose-dependant dot-blotting reaction was also observed in chicken meat samples with various dilution.

To produce expanded, minimally hard extrudates from blends of raw pork meat (20%), defatted soy flour (25%), and corn starch using a single-screw extruder, various combinations of feed moisture, process temperature, and screw speed were evaluated. First series of extrusion runs were conducted according to a central composite rotatable design/response surface methodology (RSM). Upon assessing the full model for each response, insignificant terms were eliminated to determine final response surface models. Screw speed within the range evaluated was found to have no significant effect on expansion ratio (ER) or shear force (SF) of extrudates. Since examinations of the response surfaces and their generated grids of predicted values indicated that maximum ER and minimum SF were likely to be attained with a moisture-temperature combination outside the RSM experimental range, the second series of extrusion runs were conducted with several selected combinations of moisture and temperature to determine a practical optimum extrusion condition. The combination of 22.78% feed moisture, 16$0^{\circ}C$ process temperature, and 170 rpm screw speed was chosen as such a condition, and used in the final extrusion. The final product required less force to break than did commercial pretzel sticks.

본 실험은 가공한 육제품에 첨가된 대두단백질(soy protein)을 정량하기 위한 면역분석(Immunoassay)법의 개발을 목적으로 실시하였다. Isolated soy protein(ISP)의 whole buffer extract(WBE) 분획을 SDS 처리 후 토끼에 주사하여 생산된 항혈청의 항체역가를 indirect ELISA법으로 조사하였을 시 1 : 10,000 이상에서도 반응을 나타내었다. 시료의 처리시 SDS의 최종농도가 0.03% 이상에서는 항원-항체 반응이 심각하게 저지되었으나, 0.02% 이하에서는 거의 영향을 미치지 않았다. 본 실험에 사용한 항체는 SDS로 변성된 항원(대두단백질)은 물론 SDS를 투석으로 제거한 재생항원(renatured antigen)과도 반응하였으나 그 정도는 변성항원에 비하여 약간 낮았다. 검정곡선(calibration curve)을 indirect competitive ELISA 법으로 작성하였을 시 ISP를 100 ng/100 ml까지 측정할 수 있는 감도(sensitivity)를 얻었다.

The level of fat and salt can affect the product quality and storage stability of processed meats. Additionally, consumers' demands require dietary guidelines for developing low-fat/salt functional foods. Microbial transglutaminase (MTGase), which enhances textural properties by catalyzing protein-protein cross-linkages, was introduced to develop healthier lowfat/salt meat products. The potential possibilities of low-fat/salt processed meats were reviewed under optimal conditions for functional ingredients from several previous studies. The addition of non-meat protein (e.g. sodium caseinate and soy protein isolates), hydrocolloids (e. g. konjac flour, carrageenan, and alginates), and MTGase alone or in combination with other functional ingredients improved textural and sensory properties similar to those of regularly processed meats. When MTGase was combined with hydrocolloids (konjac flour or sodium alginate) or other functional ingredients, gelling properties of meat protein were improved even at a low salt level. Based on these reviews, functional ingredients combined with new processing technologies could be incorporated into processed meats to improve the functionality of various low-fat/salt meat products.
