  • This study was conducted to observe antioxidant enzyme activity, iron content and lipid oxidation of Korean native chickens and other poultry. The breast and thigh meat of three Korean native chicken breeds including Woorimatdak, Hyunin black and Yeonsan ogye, and three commercial poultry breeds including the broiler, White Leghorn and Pekin duck (Anasplatyrhyncos domesticus) were studied. The analyses of the antioxidant enzymes activity, iron content and lipid oxidation were performed in raw and cooked samples. The activity of catalase (CAT) in the thigh meat was higher than that of the breast meat of three Korean native chickens and the broiler, respectively. The activity of glutathione peroxidase (GPx) in the uncooked thigh meat of three Korean native chickens was higher than that of the breasts. The breast meat of Woorimatdak and Pekin duck had higher superoxide dismutase (SOD) activity than the others, while only the thigh meat of Pekin duck had the highest activity. Cooking inactivated CAT and decreased the activity of GPx and SOD. The thigh meat of Woorimatdak, White Leghorn, Yeonsan ogye and Hyunin black contained more total iron than the breast meat of those breeds. The heme-iron lost during cooking ranged from 3.2% to 14.8%. It is noted that the thigh meat had higher thiobarbituric acid reactive substances values than the breast in all chicken breeds. Though Woorimatdak showed higher antioxidant enzyme activity and lower released-iron percentage among Korean native chickens, no differences were found on lipid oxidation. We confirm that the dark meat of poultry exhibited higher antioxidant enzyme activity and contained more iron than the white meat.

  • This study examined the effect of pretreated sandfish Arctoscopus japonicus meat as a surimi complex for preparing sandfish flavored fish paste. To prepare the sandfish-flavored paste, fine chopped sandfish meat including backbone was added in a ratio of 0 to 50 wt.% to thawed Alaska pollock Theragra chalcogramma surimi to make a mixed surimi gel. To prepare the sandfish-flavored paste, the mixed surimi was ground with salt using a silent cutter, mixed with starch and stabilizers 0.2% transglutaminase and gluconolactone 0.3%, stuffed in a rectangular container, left for 3 h at $25^{\circ}C$, cooked in hot water for 30 min at $90^{\circ}C$, and finally chilled for 20 min at $4^{\circ}C$. The effects of the pretreatment of sandfish meat were investigated by analyzing the quality of the paste produced. The proximate composition of FP (fish paste containing 40% steam-cooked sandfish meat and 0.3% gluconolactone) was moisture 76.1%, crude protein 12.0%, crude fat 3.8%, carbohydrate 6.1%, and ash 2.0%. The major minerals in FP were Na (23.77 mg/L), Mg (1.46 mg/L), Zn (1.04 mg/L), and Fe (0.41 mg/L), and the major free amino acids were taurine, anserine, alanine, and glutamic acid. The monounsaturated fatty acid content of FP was 566.22 mg%, and the polyunsaturated fatty acid content was 498.43 mg%. The n-3 fatty acid content was 398.01 mg%, and C20:5n-3 (218.85 mg %) was a major component.

  • The objective of this study was to compare the quality characteristics of cultured and red sea bream. The color of dorsal muscle was different between wild and cultured red sea bream. Lipid content of the dorsal muscle was higher in cultured fish than in wild one. The contents of moisture and crude protein in cultured fish muscle were almost same as those of wild one. Sensory evaluation of raw fish meat showed that cultured fish had lower preference in appearance, taste and texture than wild one. Especially the texture of cultured raw fish meat had lower preference than wild meat. For cooked fish meat, cultured fish were harder and less juicy than wild fish. These textural differences between wild and cultured meats were confirmed by objective evaluation including the measurements of hardness, springiness, and cohesiveness. Light microscopic observation showed that cultured red sea bream had more lipid in the surface layer near epidermis than wild one. Also more lipid droplet between muscle fibers were observed in cultured red sea bream by SEM.

  • 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'.

  • Objective: This research aims to explore the nutritional and bioactive peptide properties of goat meat taken from various primal cuts, including the breast, shoulder, rib, loin, and leg, to produce these bioactive peptides during in vitro gastrointestinal (GI) digestion and absorption. Methods: The goat meat from various primal cuts was obtained from Boer goats with an average carcass weight of 30±2 kg. The meat was collected within 3 h after slaughter and was stored at -80℃ until analysis. A comprehensive assessment encompassed various aspects, including the chemical composition, cooking properties, in vitro GI digestion, bioactive characteristics, and the bioavailability of the resulting peptides. Results: The findings indicate that the loin muscles contain the highest protein and essential amino acid composition. When the meats were cooked at 70℃ for 30 min, they exhibited distinct protein compositions and quantities in the sodium dodecyl sulfate-polyacrylamide gel electrophoresis profile, suggesting they served as different protein substrates during GI digestion. Subsequent in vitro simulated GI digestion revealed that the cooked shoulder and loin underwent the most significant hydrolysis during the intestinal phase, resulting in the strongest angiotensin-converting enzyme (ACE) and dipeptidyl peptidase-IV (DPP-IV) inhibition. Following in vitro GI peptide absorption using a Caco-2 cell monolayer, the GI peptide derived from the cooked loin demonstrated greater bioavailability and a higher degree of ACE and DPP-IV inhibition than the shoulder peptide. Conclusion: This study highlights the potential of goat meat, particularly cooked loin, as a functional meat source for protein, essential amino acids, and bioactive peptides during GI digestion and absorption. These peptides promise to play a role in preventing and treating metabolic diseases due to their dual inhibitory effects on ACE and DPP-IV.

  • Background: Omega-3 long-chain (${\geq}C_{20}$) polyunsaturated fatty acids (${\omega}3$ LC-PUFA) confer important attributes to health-conscious meat consumers due to the significant role they play in brain development, prevention of coronary heart disease, obesity and hypertension. In this study, the ${\omega}3$ LC-PUFA content of raw and cooked Longissimus thoracis et lumborum (LTL) muscle from genetically divergent Australian prime lambs supplemented with dietary degummed crude canola oil (DCCO) was evaluated. Methods: Samples of LTL muscle were sourced from 24 first cross ewe and wether lambs sired by Dorset, White Suffolk and Merino rams joined to Merino dams that were assigned to supplemental regimes of degummed crude canola oil (DCCO): a control diet at 0 mL/kg DM of DCCO (DCCOC); 25 mL/kg DM of DCCO (DCCOM) and 50 mL/kg DCCO (DCCOH). Lambs were individually housed and offered 1 kg/day/head for 42 days before being slaughtered. Samples for cooked analysis were prepared to a core temperature of $70^{\circ}C$ using conductive dry-heat. Results: Within raw meats: DCCOH supplemented lambs had significantly (P < 0.05) higher concentrations of eicosapentaenoic (EPA, $20:5{\omega}3$) and EPA + docosahexaenoic (DHA, $22:6{\omega}3$) acids than those supplemented with DCCOM or DCCOC; Dorset sired lambs contained significantly (P < 0.05) more EPA and EPA + DHA than other sire breeds; diet and sire breed interactions were significant (P < 0.05) in affecting EPA and EPA + DHA concentrations. In cooked meat, ${\omega}3$ LC-PUFA concentrations in DCCOM (32 mg/100 g), DCCOH (38 mg/100 g), Dorset (36 mg/100 g), White Suffolk (32 mg/100 g), ewes (32 mg/100 g) and wethers (33 mg/100 g), all exceeded the minimum content of 30 mg/100 g of edible cooked portion of EPA + DHA for Australian defined 'source' level ${\omega}3$ LC-PUFA classification. Conclusion: These results present that combinations of dietary degummed crude canola oil, sheep genetics and culinary preparation method can be used as effective management tools to deliver nutritionally improved ${\omega}3$ LC-PUFA lamb to meat consumers.

  • The objective of this study was to determine the effects of short-term presalting on pink color and pigment characteristics in ground chicken breasts after cooking. Four salt levels (0%, 1%, 2%, and 3%) were presalted and stored for 0 and 3 d prior to cooking. Cooking yield was increased as salt level was increased. However, no significant differences in pH values or oxidation reduction potential (ORP) of cooked chicken breasts were observed. Cooked products with more than 2% of salt level had less redder (lower CIE $a^*$ value) on day 3 than on those on day 0. As salt level was increased to 2%, myoglobin was denatured greatly. Myoglobin denaturation was leveled off when samples had 3% of salt. With increasing salt levels, residual nitrite contents were increased while nitrosyl hemochrome contents were decreased. These results demonstrate that salt addition to a level of more than 2% to ground meat may reduce the redness of cooked products and that presalting storage longer than 3 d should be employed to develop a natural pink color of ground chicken products when less than 1% salt is added to ground chicken meat.

  • The most abundant Orthoptera in Mexico is a small grasshopper (Sphenarium purpurascens) which is considered a food source with increased nutritional value due to its high protein content. Insect proteins have gained relevance because of their high potential as gelling, texturing, and extender agents in the food industry. The objective of this study was to evaluate the effect of substituting meat with a soluble protein extract from grasshopper obtained by alkalisation or alkalisation-piezoelectric ultrasound, on the techno-functional, physicochemical, and sensory characteristics of cooked meat models (sausages). The soluble protein was extracted in NaHCO3 pH 8 and a piezoelectric ultrasound 5-mm sonotrode at 20 kHz with 99% amplitude. Different formulations with meat substitution: 0%, 5%, 10%, and 15% were prepared and characterised for their rheological behaviour, emulsion stability, weight loss by cooking, total protein content, colour, and texture. Sensory evaluation was conducted with consumers using a test involving check-all-that-apply and overall liking. The alkalisation-piezoelectric ultrasound method improved the solubility and the techno-functional properties of the soluble grasshopper protein when applied in sausages at maximum levels of 10% meat substitution. The sensory evaluation indicated that the formulation with 5% meat substitution exhibited the same acceptability as the control sample. Given these results, the soluble protein treated with alkalisation and piezoelectric ultrasound could be used as an extender in meat products.

  • The present study investigated Bul-Chun-Wi Sacrificial Ritual (sacrificial service which has been handed down from generation to generation to worship the family ancestors in the period of $1400{\sim}1800$) and foods for the sacrificial service among fourteen head families in Andong area. The findings are as follows; 1. In Bul-Chun-Wi Sacrificial Rituals, family shrine has been maintained in good shape, and the table, dishes, and foods used in the rituals have not been changed so much until these days. 2. While vegetable soup is widely used as soup, one family uses the seaweed soup, the other soup mixed with meat, fish, and vegetable. Specially soybean-powdered soup, which is the distinguishable food in Andong area, has been used. 3. As a basic Ddock, mainly Si-Ru-Ddock(a steamed rice cake), piled up to 13-15 stacks, is used. Additional 7-9 kinds of Ddock are placed on top of the basic Ddock. 4. For grilled-meat food(Geuck), eight families use the raw meat, and one family uses the half-cooked meat. Recently, five families have used the cooked meat. Mostly used ones are meat-Geuck, fish-Geuck, chicken-Geuck, and the Geuck are not served one by one. Instead the Geuck are stacked in one dish designed for Geuck in order of meats from poultry, animal, fish, and shell. As the sub-dishes for rice, raw and cooked Geuck are used. 5. The number of stew (Tang) are 3 to 6 and 5 stews is the most popular. Commonly used stews are meat stew, fish stew, chicken stew, vegetable stew, blood stew, and organs stew. For the vegetable stew, buckwheat gel can be used. 6. As the fruit, chinese date, pear, nut and dried persimmons are the basic ones. The even number of 6 or 8 colorful fruits are used, while the odd number of 7 or 9 colorful fruits are used in three head families. 7. As Sik-Hae which is a drink and made from fermented rice, rice Sik-Hae or fish Sik-Hae has been necessarily used. 8. As raw meat dish, the liver of cow or meat is used. As a wrapping materials, the reticulum of a ruminant, green seaweed or thinly fried egg can be used.
