  • Horse fat is known to be an effective ingredient in Asia, and the horse fat itself, which is mixed with other ingredients at the additive level, is often sold as a finished product. In this case, physical properties of the horse fat raw material are important. Many horse fats produced in Korea (Jeju) have low temperature stability, so if not stored at low temperatures, segregation may occur. In the case of Japanese horse fat, it is partially hydrogenated or is used the solid phase as the horse fat by separating the liquid phase and the solid phase that is harder and more stable than the horse fat of Jeju. In this study, the physical properties were tested to improve the temperature stability even without the partial hydrogenation process of Jeju horse fat. Various oil gelling agents were used in the study. Results confirmed that the physical properties of the hydroxystearic acid added Jeju horse fat were improved. In addition, stability evaluations at temperatures of 25 ℃, 40 ℃, 45 ℃ and flow behavior evaluations at temperatures of 25 ℃, 30 ℃, 40 ℃ were performed for Jeju horse fat with hydroxystearic acid, 100% Jeju horse fat, and 100% Japanese horse fat. Results showed that the Jeju horse fat improved in flow behavior by adding hydroxystearic acid similar to that of Japanese horse fat. In addition, when the crystal state was observed under a microscope, the thermal stability was improved by decreasing the size of the needle-type crystals with the addition of hydroxystearic acid. Jeju horse fat containing hydroxystearic acid was found to have no physical problems even when stored at room temperature for a long time.

  • Horse fat was vacuum-extracted from fatty tissues of Jeju and Halla horse meat and their physicochemical properties were compared to those of commercial lard and beef-tallow. For color, ${\Delta}E$ was found to be decreased when crystallized. Although acid values of horse fat were higher than those of lard and beef-tallow, p-anisidine and totox values were lower. The iodine value of beef-tallow was the lowest (44.61), and those of horse fat and lard were similar (57.53-57.74). Only horse fat contained ${\alpha}-tocopherol$. The contents of ${\gamma}-tocopherol$ in Jeju and Halla horse fat, lard, and beef-tallow were 7.08, 4.57, 2.13, and 1.91 mg/kg, respectively. Palmitoleic acid ($C_{16:1}$) was found in horse fat. Melting and crystallization curves of horse fat displayed two endothermic and exothermic peaks which were differentiated from lard and beef-tallow. These results indicated that horse fat demonstrates different physicochemical properties compared to lard and beef-tallow, when applied to various types of lipid products.

  • Horse meat is a low-fat and high-protein food with more essential amino acids and less fat than other meat, but the horse meat has not been popularized in Korea due to stereotypes about horse meat. In this study, a comparative analysis of horse meat and beef was conducted using electronic nose device and gas chromatography, and as a result, there was no significant difference in the scent. However, the oleic acid content of beef is significantly higher than that of horse meat(p<0.05). Therefore, the possibility of popularizing horse meat processed products in the domestic meat processing market is expected to be sufficient.

  • Horse fat was extracted from fatty horse meat at $70^{\circ}C$ under vacuum conditions. The oxidative stability of horse fat was investigated by the addition of 0, 30, 60, and 150 mg/kg of ${\alpha}$-, ${\gamma}$-, or ${\delta}$-tocopherol during storage of 14 days at $65^{\circ}C$ in the dark. Changes of tocopherol concentration and fatty acid composition, peroxide value, and 2-thiobarbituric acid (TBA) value were analyzed during storage. The levels of the added tocopherols were found to decrease during storage. Unsaturated fatty acids contents of horse fat without tocopherol decreased from 60.87% to 57.22% after 14 days. The peroxide value and TBA value increased as storage time increased. The peroxide values of horse fat after addition of 0, 30, 60, and 150 mg/kg of ${\gamma}$-tocopherol were 43.75, 25.17, 20.87, and 15.41 meq/kg, respectively, and the TBA values were 7.87, 5.64, 4.43, and 4.23 mg malonaldehyde (MA)/kg, respectively, after 14 days. At the concentration of 150 mg/kg, both ${\gamma}$- and ${\delta}$-tocopherol impeded the oxidation of horse fat during storage.

  • Pituitary pars intermedia dysfunction (PPID), often referred to as equine Cushing's disease, is a common endocrine disorder often diagnosed in older horses. A 13-year-old 460 kg Warmblood gelding showed clinical signs suggestive of PPID, including hypertrichosis, fat redistribution, polyuria and polydipsia (PU/PD), and weight loss. Physical examination, complete blood cell count, and serum chemistry results were normal. However, dexamethasone suppression and plasma adrenocorticotropic hormone (ACTH) level tests confirmed PPID. Three months after the confirmed diagnosis, the horse was referred again with symptoms of laminitis. Radiography and venography were performed to evaluate the laminitis severity level. However, the foot condition continued to worsen, and the horse was eventually euthanized. The purpose of this case report is to describe clinical signs and diagnosis of PPID with laminitis.

  • The objective of this study was to evaluate the quality of emulsion-type sausage where part of the pork was substituted with horse meat during manufacturing. Three treatments of sausages were manufactured by replacing pork with 0, 50 and 100% horse meat. After manufacturing, sausages were vacuum-packaged and stored 4℃ for 1 day. An increase in horse meat resulted in higher moisture, protein content, and pH values, and lower fat content of sausage(P<0.05). However, no significant effects were observed on texture characteristics and sensory attributes of sausage. The horse meat sausage had higher K, Fe, Zn, Cu, saturated fatty acid contents than 0% horse meat level. Based on the results, it can be concluded that horse meat can be used as a meat replacer in the manufacture of emulsion-type sausages up to a level of 100%.

  • The objective of this study was to evaluate the effect of different ratios of horse meat and pork (horse meat: pork=0:100, 50:50, 100:0) on the quality and sensory characteristics of press hams. Press ham containing 100% horse meat had a higher moisture content (%) and lower fat content (%) than the other hams (p<0.05). The redness (hunter a value) and yellowness (hunter b value) were significantly higher in press ham containing 100% horse meat, whereas the lightness (hunter L value) was significantly lower than other hams (p<0.05). With regard to textural properties, press ham containing 100% horse meat had significantly higher springiness, but there were no significant differences among the ham products in regard to hardness, cohesiveness, gumminess and chewiness (p>0.05). The results of sensory tests showed that press ham containing 100% horse meat had significantly lower color and acceptability scores compared to other hams (p<0.05). With regard to mineral contents, Na, Fe, Mn, and Zn were significantly higher in press ham containing 100% horse meat (p<0.05).

  • To enhance the consumption of horse meat, its nutritional composition was analyzed and compared to that of white meat (i.e., chicken and duck), which consumers consider healthy. Horse meat samples used in the experiment were classified by breed and grade as follows: Jeju horse (grade $1^+$ and 1), Jeju crossbred horse (grade 1 and 2), Thoroughbred (no grade), and cuts (loin, chuck roll, and arm picnic). In an analysis of general components and cholesterol, the horse meat was confirmed as a low-fat, high-protein, and low-cholesterol food material. In an amino acid analysis, horse meat contained a higher proportion of essential amino acids than white meat. The fatty acid compositions were also analyzed. The content of linolenic acid, an essential fatty acid, was significantly higher in all horse meat groups than in Ross chicken and Pekin duck meat. The content of palmitoleic acid showed similar results. In a mineral analysis, the levels of Fe and Zn in horse meat were higher than those of white meat. The mineral content was as follows except for the leg of shite meat: K > P > Na > Mg > Ca > Zn > Fe.

  • The present work describes the effect of slaughtering age on horse carcass traits and on meat quality. Eighteen male Italian heavy draught horse (IHDH) breed foals were employed in the study. Soon after foaling they were randomly subdivided in 3 groups according to 3 age at slaughtering classes: 6 months old, 11 months old and 18 months old. Live weight, hot carcass weight and dressing percentage of each animal were recorded. After slaughtering, meat samples were collected from Longissimus Dorsi muscle between 13th and 18th thoracic vertebra of each animal and then analyzed. The right half carcass of each animal was then divided in cuts. Each one was subdivided into lean, fat and bones. Then, the classification of the lean meat in first and second quality cuts was performed according to the butchers' customs. Older animals were characterized by a lower incidence of first quality cuts (p<0.01) on carcass. Younger animals showed greater content in protein (p<0.01). Fatty acid profile showed an increasing trend of PUFA connected to the increasing of slaughtering age (p<0.05). The unsaturation index of intramuscular fatty acids was not affected by slaughtering age, confirming that horse meat, if compared to beef, is more suitable from a nutritional point of view. Season influenced reproduction, birth as well as production aspects of this species. The different slaughtering age could represent the way to produce meat of IHDH foals during the entire year without change in the qualitative standard expected by consumers.
