The perception and attitude of dietitians on processed meats with seasoning were investigated. Questionnaires were distributed to 176 dietitians at school foodservice operations in Kyungnam province. In the survey results, about half (Ed-better to give the exact number of percentage) of the dietitians answered that it is ‘necessary’ to develop processed meats with seasoning. Regarding desired product characteristics, the dietitians were asked about-reduced additive use, good hygienic quality, nutritious and healthy quality, low salt content and adequate supply of nutritional information. Over half of the dietitians-(65.5%) preferred Korean style processed meats with seasoning. The cooking types chosen as new developments for Korean processed meats with seasoning were grilled (36.2%), fried (19.8%), and roasted (18.6%). The dietitians wanted no or only a little increase in the price compared to current commercial products, 1kg (50.6%) size as the package unit and 7 days (45.1%) shelf life under refrigerated or frozen storage.(Ed-confirm the highlighted changes) A majority of the dietitians (64.2%) responded positively to buy the processed meats with seasoning if the products meet their needs.

This experiment was carried out to find out the effect of packing methods on physico-chemical properties of breast and thigh meats in chicken, which was dried by air spray chilling method. The chicken carcass was cut into breast and thigh muscles, which were either vacuum packed or atmosphere packed, and stored at -2O˚C for 1, 4, 8, 12 and 16 wk after quick freezing at -45˚C for 35 min. The pH values of atmosphere-packed breast meat and vacuum-packed breast meat after one wk of storage were higher than those of atmosphere-packed thigh meat and vacuum-packed thigh meat(P< .05). The pH values increased as storage period extended, but no significant difference was detected between two packing method(vacuum vs. atmosphere). Total moisture contents of breast meats after one wk of storage were higher than those of thigh meats. The total moisture contents decreased slowly as storage period extended, but no significant difference was detected between two packing method(vacuum vs. atmosphere). The shear force value of thigh meat was higher than that of breast meat. The shear force values of both meats decreased as storage period extended, regardless of packing method. The water soluble protein extractability of thigh meats was higher than that of breast meat, and the water soluble protein extractability of all treatments decreased until 8 wk after storage, but increased gradually after 8 wk of storage period. The salt soluble protein extractability of breast meat was higher than that of thigh meat, and the salt soluble protein extractability of all treatments decreased as storage period extended. With regard to the packing method, the vacuum packing showed higher value than that of atmosphere packing method until 8 wk of storage. Total lipid contents of atmosphere- and vacuum-packed thigh meats at 1 wk of storage were higher than those of breast meats, and the total lipid contents of all of treatments decreased as storage period extended. However, no significant difference was detected between two packing methods. The fatty acid contents of breast and thigh meats were in order of o1eic(33,5~42.4), palmitic(19.7~30.8) and linoleic acid(10.8~17.4).

Objective: The adulteration of raw beef (BMr) with dog meat (DMr) and pork (PMr) becomes a serious problem because it is associated with halal status, quality, and safety of meats. This research aimed to develop an effective authentication method to detect non-halal meats (dog meat and pork) in beef using metabolomics approach. Methods: Liquid chromatography-high resolution mass spectrometry (LC-HRMS) using untargeted approach combined with chemometrics was applied for analysis non-halal meats in BMr. Results: The untargeted metabolomics approach successfully identified various metabolites in BMr DMr, PMr, and their mixtures. The discrimination and classification between authentic BMr and those adulterated with DMr and PMr were successfully determined using partial least square-discriminant analysis (PLS-DA) with high accuracy. All BMr samples containing non-halal meats could be differentiated from authentic BMr. A number of discriminating metabolites with potential as biomarkers to discriminate BMr in the mixtures with DMr and PMr could be identified from the analysis of variable importance for projection value. Partial least square (PLS) and orthogonal PLS (OPLS) regression using discriminating metabolites showed high accuracy (R² >0.990) and high precision (both RMSEC and RMSEE <5%) in predicting the concentration of DMr and PMr present in beef indicating that the discriminating metabolites were good predictors. The developed untargeted LC-HRMS metabolomics and chemometrics successfully identified non-halal meats adulteration (DMr and PMr) in beef with high sensitivity up to 0.1% (w/w). Conclusion: A combination of LC-HRMS untargeted metabolomic and chemometrics promises to be an effective analytical technique for halal authenticity testing of meats. This method could be further standardized and proposed as a method for halal authentication of meats.

The consumer demands for quality of meats has become diverse in recent years. The present paper describes mainly the technology to improve the broiler meat quality with special reference to reducing fat contents in edible meats which is the heart of the quality constraints. Abdominal fat deposition in broilers was reduced by feeding of medium-chain triglycerides(MCT), suggesting MCT feeding is useful to produce broiler meat with low fat content. A phase feeding system to aim at improving meat quality that is mainly comprised with partial replacement of dietary protein into phase during 4∼6 weeks increased edible meat yields and reduced abdominal fat deposition and fat contents in breast and thigh meats. Whiteness of fat tissue was intensified by feeding beef tallow or lard in place of yellow grease. Feeding Phaffia yeast containing astaxanthin increased redness of breast and thigh meats and improved visual appearance of meats which may be preferential for consumers. Feeding fish oil reduced abdominal fat deposition and increased EPA and DHA contents of fat tissues. These procedures could be used for manipulation of meat quality to meet consumer demands.

Based on the theory of planned behavior, this study aims to examine the structural equation model among consumers' concerns and purchase intentions for alternative meats. Data were collected from 300 adults living in Kyeonggi Province. Results show that animal welfare, environmental concern, and health concern all have a direct and significant effect on purchase intention of alternative meat, and the mediation effect is also significant, indicating a partial mediation effect. The image of a company as caring about animal welfare and contributing to public causes can help sell alternative meats. Media publicity focusing on animal welfare for alternative meats can improve the attitudes of domestic consumers as well as their intention to purchase alternative meat products.

The purpose of this study was to examine the perceptions and attitudes held by dietitians on seasoned processed meats. The questionnaires were distributed to x (Ed- give the sample size) dietitians at business foodservice operations in Kyungnam province. According to survey, 37.5% of the dietitians answered that it is 'very necessary' to develop seasoned processed meat products. Regarding desired product characteristics, the dietitians were asked about reduced additive use, good hygienic quality, nutritious and healthy quality, low salt content and adequate supply of nutritional information. Over half of the dietitians (59.2%) preferred Korean style seasoned processed meats. The cooking types of Korean seasoned processed meats chosen as new developments were steamed (21.3%), roasted (20.6%) and pilled (18.1%), while the expected frequencies of product usage were in the order of grilled (18.8%), roasted (15.6%), and fried (14.4%). The dietitians wanted no or only little increase in the price compared to current commercial products, units packed in 1 or 3kg sizes and a shelf life under refrigerated or frozen storage of 3-7 days. A minority of the dietitians (40.6%) responded positively to buy the seasoned processed meats if the products meet their needs.

This study was carried out to obtain information about preferences of the meat food in 491 Koreans including the ones living in New Zealand. General preference for the meats was not significant differences according to sex, monthly income level, residing area, marriage status and family number. Degree of preferences for the meats which have consumed commonly such as beef, pork and chicken showed relatively a high tendency, but the meats such as goat, lamb, deer and turkey were very low in preference score. In the meats cooking style, most subjects preferred Korean style followed by Chinese and western style. The younger had a high score than the older inpreference of the processed meats. The meat foods subjects preferred were Tzeams, Kui, Tangs, cutlets and Tangsuyuks. There were not significant differences in preferences for the meats between Korean living in domestic and New Zealand. This study showed that the meat foods which theirs preference was high have had a high tendency in the intake frequency also. Preferences for the meat food was affected by intake frequency and amount of intake and nutritional knowledge, but not related to BMI, health status and monthly income level.

The objective of this study was to predict total bacteria count of pork meats by using the portable electronic nose systems developed throughout two stages of the prototypes. Total bacteria counts were measured for pork meats stored at $4^{\circ}C$ for 21days and compared with the signals of the electronic nose systems. PLS(Partial least square), PCR (Principal component regression), MLR (Multiple linear regression) models were developed for the prediction of total bacteria count of pork meats. The coefficient of determination ($R_p{^2}$) and root mean square error of prediction (RMSEP) for the models were 0.789 and 0.784 log CFU/g with the 1st system for the pork loin, 0.796 and 0.597 log CFU/g with the 2nd system for the pork belly, and 0.661 and 0.576 log CFU/g with the 2nd system for the pork loin respectively. The results show that the developed electronic system has potential to predict total bacteria count of pork meats.
