  • To prevent the denaturation of ficin(EC 3.4.22.3) that is a proteolytic enzyme in fig(Ficus carica L.), fig conserve was heated to 55oC. The fig conserve was added as a tenderizer to native Korean cattle beef(KCB), dairy cattle beef(DCB), castrated dairy cattle beef(CDCB), and imported beef(IB). The composition of free amino acids, hydroxyproline content, shear force, cooking loss, morphological changes and sensory evaluation were then investigated to observe the effect of tenderizing beef with fig conserve. Free amino acids and cooking loss of treated beef were higher than those of control, whereas hydroxyproline and shear force were lower. Glutamine in treated beef decreased relatively but asparagine increased. Hydroxyproline was found, in increasing order of abundance, in DCB, CDCB, IB and KCB. By portion, loin was higher than tenderloin in free amino acids, hydroxyproline and shear force but was lower in cooking loss. Observation with a light microgram revealed a surprising loss of muscle fiber in treated beef. In sensory evaluation of uncooked beef, the control was redder than the treated beef(p<0.01~p<0.05). Treatment with fig conserve increased the juiciness of both cooked CDCB and IB(p<0.001) and decreased their hardness(p<0.01~p<0.001).

  • This review addresses the role of fat in beef palatability and healthfulness. Particular emphasis is placed on the content of oleic acid in beef, and how this increases with time when cattle are fed a grain-based diet. Oleic acid decreases the melting point of lipids from beef, increasing the perception of juiciness and improving beef flavor. Clinical trials have demonstrated that ground beef containing elevated oleic acid increases, or at the least has no negative effects on the concentration of HDL cholesterol. The amount of fat in published ground beef intervention trials greatly exceeds the amount of fat in equivalent portions of beef from U.S. domestic or Korean Hanwoo cattle. Thus, we conclude 1) Beef cattle should be raised under production conditions that increase the concentration of oleic acid in their edible tissues (i.e., by grain feeding over extended periods of time); and 2) The amount of fat consumed in a typical portion of beef will not increase risk factors for cardiovascular disease.

  • This study examines how consumer attitudes toward food origin and health concerns influence beef purchasing behavior. Using data from the Korea Rural Economic Institute's food consumption behavior survey, we analyzed the frequency of purchasing domestic and imported beef. Results indicate that when not distinguishing between domestic and imported beef, perceptions of lower origin quality and higher health concerns are associated with an increase in purchasing frequency. However, such influences are statistically insignificant for imported beef. Further analysis reveals that for consumers exclusively purchasing domestic beef, these factors do not significantly impact purchasing frequency, while for consumers simultaneously purchasing both domestic and imported beef, these factors do significantly impact purchasing frequency.

  • The objective of this study was to examine the effect of hot-boning and soy sauce as a curing agent on the processing properties of beef jerky. Beef jerky was prepared under the following four treatment conditions; Beef jerky with cold-boned beef and salt solution, beef jerky with cold-boned beef and soy sauce solution, beef jerky with hot-boned beef and salt solution, and beef jerky with hot-boned beef and soy sauce solution. Cured meat and jerky containing hot-boned beef had a significantly higher pH, water holding capacity (WHC), moisture content, Myofibrillar fragmentation index (MFI), processing yields, tenderness, and sensorial scores than samples containing cold-boned beef (p<0.05). Regardless of the raw materials, the jerky containing soy sauce had a significantly lower pH, WHC, moisture content, salt content, TBA, CIE $L^*$ and $b^*-$ values, and significantly higher MFI, mechanical tenderness, and sensorial scores (p<0.05). Based on these findings, we concluded that the use of hot-boned meat and soy sauce was the most effective boning method and curing agent during beef jerky processing.

  • This study examined the usage, perception and willingness to use beef traceability. The data were collected from 255 housewives in Busan and Gyeongnam region through a self-administered questionnaire. Frequency, Cronbach's ${\alpha}$, t test, one-way ANOVA, Duncan's multiple range test, Pearson's correlation analysis, and multiple regression analysis were conducted by SPSS Windows V.20.0. Only twelve percent of the respondents experienced to use beef traceability. Most respondents checked it by kiosk or bar code reader in a store. On the other hand, eighty-eight percent did not use beef traceability. The reasons for not usage of it were "Do not know beef traceability very well", "Do not know how to use beef traceability", and "Information from packing or counters is reliable" in order. In the level of perception of beef traceability, safety assurance was highest, followed by information quality, usefulness, and information accessibility. The percentage of correct answers of knowledge about beef traceability was not high. The multiple regression analysis showed that employment status, knowledge about beef traceability, information quality, information accessibility, and usefulness were significant factors to affect the willingness using beef traceability.

  • This study investigated data on beef dietary consumption during the Joseon Dynasty Period, including "the Annals of the Joseon Dynasty", "the Diaries of the Royal Secretariat", and "Ilsongnok". Beef stands for superstitions as well as respect, broad-mindedness, exquisite culinary taste, and is a symbol of taste. In the historic record, we found two extremely opposite trends; specifically, Ugeum (牛禁, forbidding beef consumption and indulgence in beef). On the one hand, believing that they were the rudimentary foundation to Korea's agriculture, Joseon authorities tried to protect cows and bulls as valuable agricultural assets. Meanwhile, there were several officially sanctioned beef consumption events in the Joseon period. These included Jesu (祭需, food for ancestral rites), Daejup (待接, servings), Hasa (下賜, bestowment), and Hogue (犒饋, comforting soldiers with culinary methods). These included offerings to the departed spirits, servings, bestowment, and comforting soldiers with culinary methods. Especially in Joseon's Yeonhang (燕行) Journals, we can see different beef distributions and preferences between Japan and China. Furthermore, The Annals of the Joseon Dynasty even addressed the general issue of beef treatment; special methods for beef processing, beef distribution, tool materials, and prices of beef.

  • Thoughts on beef consumption and Korean beef were surveyed through questionnaire, with 150 housewives living in Seoul and its metropolitan area as subjects. The reasons for buying Korean beef were revealed as taste/quality(56.5%) and sanitation/safety(27.8%). The places of purchase were meat shops(42.3%), department stores, discount stores or super stores(28.1%), and agricultural cooperative stores or livestock cooperative stores(19.9%). The average purchase amount of Korean beef was 0.84 kg and the price was 22 USD(20,944 Won; 1 USD = 950 Won), and 61.7% of consumers thought the price of Korean beef was expensive. The major reason for buying imported beef was indicated as low price(78.0%) and the purchase locations were discount stores, department stores(39.4%) and meat shops (31.1%). When the subjects were surveyed on brands of Korean beef 73.3% had heard of branded beef but only 48% had purchased it. The reasons for buying branded beef were revealed as taste(40.0%) and sanitation(25.2%). When subjects were asked to compare branded beef with general Korean beef, 51.1% gave an answer of 'Very good/Good' for taste and quality, 'Similar' was 22.4% and 'No difference' was 29.9%, suggesting that the trust for branded beef was not strong yet. The important factors for buying branded beef were indicated as quality/taste(54.9%) and sanitation/safety(38.9%) and subjects were willing to pay up to 18.0% more for branded beef compared to the price of general Korean beef.

  • This various factors that affect beef consumption behavior between different types of beef such as Hanwoo, Australian, American, and domestic Yukwoo. Previous studies usually used almost ideal demand system (AIDS) model to show the degree of substitution between meats especially domestic and foreign beef. This a real expenditure each individual and to explain what factors affect consumers especially focusing on various beef. Hence, previous studies used shares and prices as key variableshowever, this study use various socio-demographic variables, consumption tendency, satisfaction and importance for beef consumption, purchasing usage and part, etc. This study a seemingly unrelated regression (SUR) model to enhance efficiency of estimates because error terms of four beef consumption equations are correlated. For, an on-line survey was performed Aug. 5 - 14, and we obtained 979 effective samples. The results show that high income group (more than 700 mil. won per month) purchases more beef than other groups. The origin of orders is Hanwoo, Yukwoo, Australian beef, and American beef. A family who member purchases more Yukwoo than other groups. foreign affects beef consumption regardless of its origin. Individuals who think origin and taste prefer Hanwoo. However, individuals who think price prefer Australian beef.

  • The purpose of this study is to determine potential associations among consumer preference for American beef, consumers' involvement in selection of desired beef, and their intentions to purchase beef. In order to meet the above purpose, this study surveyed the visitors who shopped at 2 big discount stores selected in each of 3 metropolitan cities(Seoul, Daejeon and Daegu) from July 11 to 13, 2008. Total 278 sheets of the questionnaire were collected and used for final data analysis. As a result, it was found that the consumers responded most sensitively to the safety of food when buying beef but didn't care much about the amount of fat and beef brand. In terms of imported beef, it was found that Australian beef was considered reliable by consumers, and their preference for Korean beef was positively correlated with that for Australian beef. In addition, in regard to the attributes of beef selection, it was found that low involvement group had higher intentions to purchase American beef than high involvement group. In order to determine the potential effects of consumers' involvement in the attributes of beef selection on their intentions to purchase American beef, this study conducted data analysis in control of consumer preference for American beef. As a result, it was found that consumers' involvement in the attributes of beef selection had significant effects on their intentions to buy American beef. And sex was found to be one of the demographic characteristics associated with involvement in the attributes of beef selection, particularly associated with low involvement. Depending on sex, it was found that women had lower preference for American beef than men.
