To assess the quality characteristics of black-goat meat extracts and to develop their quality index, the ingredient ratio, manufacturing process and general composition of black-goat meat extracts were investigated. A partial meat of black-goat had high protein content(20.2∼21.6%) and low lipid content (1.9∼3.3%). The crude protein contents, 3.5∼6.1%, of black-goat meat extracts had a high correlation (r=0.88, p<0.01) with black-goat meat content and the soluble solid content had a high correlation (r=0.87. p<0.01) with the subsidiary material content. Two commercial products had total bacteria of 10$^1$∼10$^2$ cfu/ ml. showing the necessity of pressure sterilization of final process.

The present research was designed to collect recipe of set up a standard recipe and analyze the nutrients of broiled black goat meat (a kind of native local foods in Busan and south province). The results of the study are summarized as follows. The recipe for goat(lamb) meat was recorded in Sanlimkyounggae and Jungbosanlimkyounggae between 1715 and 1827. The goat meat was explained as food for health, rejuvenation and recuperation Since late 1800, it has been utilized for such use. The flavor of broiled black goat meat is influenced by seasonings, fruit juice, heating treatment and cooker. And it also could be affected by the method of slaughter and the sex of the goat. There are lot of element in seasoning. Red pepper paste, garlic and ginger holdback the bad smell and make the taste better. Onion help to retain the water and improve the flavor. Starch syrup, sugar and sesame oil make the meat smoother, glossier and more tasty. The meat is usually roasted on grill over charcoal. It helps to remove or suppress the bad smell and make the taste better. Softness and scent of the meat depend largely on the way to butcher. Female goat meat tastes smoother and smells better. Fruit juice also improve the softness of the meat. Energy per 100g of the 'broiled black goat meat' is 170kcal. There are protein (23g), fat(2.4g), Ca(159mg), Fe(1.1mg) and so on. Amino acid is mainly comprised of essential amino acid such as cystine, lysine, leucine, and arginine. Fatty acid consists primarily of unsaturated fatty acid like oleic acid, linoleic acid.

This study was designed to investigate the characterization of black goat meat and bone beverage containing honey of red ginseng. The crude proteins and moisture contents of black goat meat were higher than those of pork and beef, but the crude lipid content of black goat meat was lower than that of those. The potassium content of black goat meat was lower than that of chicken, but similar to the pork and beef. The sodium content of black goat meat was lower than that of chicken, pork and beef. The result of the sensory evaluation of black goat meat and bone beverage added honey with red ginseng by 25 panels, was that the beverages added $7.5\%\;and\;8.0\%$ honey with red ginseng were better than any other beverages. Thus, the results suggest that the black goat meat bone beverage added honey with red ginseng could be one of valuable drinks.

To investigate the relationship between muscle fiber characteristics and meat quality traits by age of Korean native black goat (KNBG), four muscles (longissimus dorsi, LD; psoas major, PM; semimembranosus, SM; gluteus medius, GM) were obtained from five adult goat (AG; 18 months old) and five young goat (YG; 9 months old). PM muscle had the highest fiber number percentage (FNP) and fiber area percentage (FAP) of type I, followed by SM, GM, and LD muscles. FNP and FAP of type IIB were significantly (p<0.001) higher in AG than those in YG. YG had higher L^* values but lower b^* values than AG. The highest L^* and b^* values were observed in LD muscle (p<0.001). Age and muscle type had detrimental (p<0.001) effect on shear force and collagen content for all muscle in AG as compared to YG. YG had significantly (p<0.001) higher myofibrillar fragmentation index (MFI) than AG for all four muscles. These results suggest that muscle fiber compositions of different muscle types of KNBG depend on age, resulting in variations of meat color, MFI, collagen content, and shear force.

Objective: In this study, we evaluated the nutritional value and antioxidant activity of black goat loin (BGL) and black goat rump (BGR) meat. Methods: We evaluated the proximate compositions, collagen and mineral contents, and fatty acid compositions of BGL and BGR with respect to their nutritional value. The levels of bioactive compounds such as L-carnitine, creatine, creatinine, carnosine, and anserine were also measured. The ferric reducing antioxidant power (FRAP), 2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging, and oxygen radical absorption capacity (ORAC) were assessed to evaluate the antioxidant activity of BGL and BGR. Results: BGR showed higher collagen, Fe, Ca, P, and Na contents than did BGL (p<0.05). Notably, the Ca/P ratio was high in both BGR and BGL (1.82 and 1.54, respectively), thus satisfying the recommendation that the Ca/P ratio is between 1 and 2. BGL showed a significantly higher content of desirable fatty acids (stearic acid and total unsaturated fatty acids) than did BGR. In addition, the levels of creatine, carnosine, and anserine in BGL were higher than those in BGR (p<0.05). There was no significant difference in the antioxidant activity between BGL and BGR, as assessed by FRAP (both $15.92{\mu}mol$ Trolox equivalent [TE]/g of dry matter [DM]), ABTS (12.51 and $12.90{\mu}mol\;TE/g\;DM$, respectively), and ORAC (101.25 and $99.06{\mu}mol\;TE/g\;DM$, respectively) assays. Conclusion: This was a primary study conducted to evaluate the differences in nutritional value and antioxidant activity between loin and rump cuts of black goat meat. Our results provide fundamental knowledge that can help understand the properties of black goat meat.

This study assessed the effects of non-stunning (NS) and head-only electrical stunning (HOES) slaughtering condition on meat quality traits of longissimus lumborum (LL) muscle from Korean black goat (KBG). Ten KBGs (18 months) were assigned into two groups and exposed to either NS or HOES treatments. Blood loss (BL) % was measured after exsanguination, and meat quality traits including muscle pH, meat color measurements (CIE $L^*$, $a^*$, $b^*$, Chroma, and hue angle), water-holding capacity (WHC), Warner-Bratzler shear force (WBSF), and sarcomere length were measured at 24 h postmortem. Results indicated that NS and HOES had no significant difference on BL %, the rate of pH decline, meat color properties, and WHC (p>0.05). It has only a small effect on WBSF and sarcomere length values, but the difference was marginal. These results suggested that meat quality of LL muscle from goat might not be affected by slaughter methods because neither NS nor HOES did result in poor quality of meat.

This study examined the effects of different wet-aging times on the physicochemical characteristics and microbial profile of longissimus lumborum (LL) and biceps femoris (BF) muscles from Korean native black goat (KNBG) meat. The water holding capacity (WHC), pH, cooking loss, shear force, meat color, free amino acid, total bacteria, and coliform count of KNGB meat were analyzed at 0, 5, 10, and 15 days of wet-aging at 4℃ under vacuum packaging. The results showed that different wet-aging times led to significant pH variations between the muscles throughout the aging period. The wet-aging time did not affect the WHC and cooking loss in meat from the LL muscle. In the BF muscle, however, meat wet-aged for five days had a significantly higher WHC and less cooking loss than meat aged for 0, 10, and 15 days. The meat from the LL muscle wet-aged for five days produced tenderer meat (low shear force value) than the unaged meat (p < 0.05). Moreover, the color was similar in the LL muscle regardless of the number of aging days. In the BF muscle, the redness (a*) was higher in the meat wet-aged for 15 days compared to that aged for 0, 5, and 10 days (p < 0.05). Regardless of the muscles, an increase in wet-aging time led to an increase in the total free amino acids contents in both muscles (p < 0.05). On the other hand, the tasty/bitter amino acid ratio was significantly higher for five days of wet-aged meat than 10 and 15 days of aging from the BF muscle. In addition, regardless of the muscles, the total bacteria and coliform counts were significantly lower for five days of wet-aged meat than 10 and 15 days of aging (p < 0.05). Therefore, chevon wet-aged for five days is an optimal aging period under vacuum packaging that fortifies meat quality with a minimal microbial negative defect.

The aim of this study was to determine meat quality characteristics and fatty acid composition of Korean native black goats (KNBG) finished on intensive feeding of alfalfa (ALF) and conventional feeding of commercial concentrate pellets (CCP) with low-energy common grasses. Ten KNBG (12 months old) were divided into two groups and subjected to either ALF or CCP treatments. The goats were slaughtered after 6 months of feeding with experimental diets to investigate meat quality characteristics and fatty acid compositions of longissimus lumborum muscle. There were no significant differences in proximate chemical composition, collagen, or myoglobin content between ALF and CCP groups of goats. Meat color, water-holding capacity, or tenderness was not significantly different between the two groups either. However, proportions of monounsaturated fatty acids and polyunsaturated fatty acids were significantly (p<0.05) different between the two groups. The proportion of oleic acid was significantly (p<0.05) higher in ALF goat whereas proportion of linoleic and arachidonic acids were significantly (p<0.05) higher in CCP goat. Results suggest that KNBG finished with intensive feeding of alfalfa could produce goat meat with desirable fatty acids for human diets.

The supplementation effects of sea tangle powders were determined for the meat quality in Korean native black goats. A total 90 castrated male black goats at 3-month age were divided into 3 dietary treatment groups: control (basal diet + mineral block), T1 (0.3% sea tangle feeding with the basal diet), T2 (0.9% sea tangle feeding with the basal diet). At 9-months feeding, 10 goats per treatment group were slaughtered, and the longissimus dorsi muscle samples were vacuum-packed, and subsequently analyzed for physicochemical evaluations. Analysis revealed decrease in the shear force and TBARS values of meat in the sea tangle dietary groups (p < 0.05). The T2 group exhibited increased levels of unsaturated fatty acids such as C16:1, C18:1, C18:2, and C20:4 (p < 0.05). The content of free amino acids with desirable taste such as aspartic acid, glutamic acid, glycine, histidine, and serine were higher in T2, whereas alanine content was higher in both sea tangle dietary groups, as compared to control (p < 0.05). These data indicate that feeding dietary sea tangle as an alternative mineral source results in an improvement in the physicochemical profiles of goat meat.

Speries-related meat flavors were investigated for red meats (bovine, porcine, caprine, and ovine). Volatile branched-chain fatty acids (VBCFAs) including 2-methylbutanoic, 3-methylbutanoic, 4-methylpentanoic, 2-ethylhexanoic, 4-methylhexanoic, 4-methyloctanoic, 6-methyloctanoic, 4-ethyloctanoic, 4-methylnonanoic, and 2-ethyldecanoic acids were identified in the meats from cow (bovine), pig (porcine), goats (caprine ; American white goat and Korean black goat), and lamb (ovine). Beef flavor of bovine meat was characterized by the basic meaty flavor, lacking in goaty and muttony flavor impacts due to low or absent in 4-methyl.octanoic and 4-ethyloctanoic acids. Porcine meat contained the least number of VBCFAs among sample species tested, and 3-methylbutanoic acid contributed to the unclean sweaty odor of pork. Caprine meat from Korean black and American white goats lacked in short VBCFAs (C5, C6, and C7) and contained 4-methyloctanoic and 4-ethyloctanoic acids contributing to the characteristic goaty flavor of caprine meat. Caprine meat flavor was distinctively characterized by 4-ethyloctanoic acid, while 4-methyloctanoic acid provides sweaty-muttony flavor to ovine meat. Although kinds of VBCFAs are same in two different varieties of caprine meats, meat sample from Korean black goat had stronger goaty odor and contained higher concentration of 4-ethyloctanoic acid than the meat sample from American white goat did.
