This study was conducted to evaluate meat quality traits, proximate composition, fatty acid profile and sensory attributes of pork produced under free-range and semi-intensive pig rearing systems. Longissimus dorsi muscles from pork carcasses were taken just after the slaughtering of finishing pigs reared under semi-intensive and free-range systems to test the meat quality parameters (pH, color, water holding capacity, and cooking loss), proximate composition (moisture, protein, fat, and ash) and fatty acid profile. Furthermore, the organoleptic properties were evaluated using 30 untrained panelists. The results revealed that the system of rearing did not affect (p > 0.05) the proximate composition, water holding capacity, color, pH and cooking loss of pork along with the fatty acid composition except for vaccenic acid (p < 0.05). The monounsaturated fatty acid (MUFA) content was affected (p < 0.05) by the rearing system while no effects were observed on the unsaturated fatty acid: saturated fatty acid ratio and omega-six to omega-three fatty acids ratios (p > 0.05). No difference was observed (p > 0.05) concerning the sensory attributes although pork obtained from the free-range system had the highest scores. In conclusion, the system of rearing did not show a significant effect on the meat quality parameters, composition and sensory attributes of pork obtained from cross-bred pigs.

Edible insects are gaining popularity as a potential future food source because of their high protein content and efficient use of space. Black soldier fly larvae (BSFL) are noteworthy because they can be used as feed for various animals including reptiles, dogs, fish, chickens, and pigs. However, if the edible insect industry is to advance, we should use automation to reduce labor and increase production. Consequently, there is a growing demand for sensing technologies that can automate the evaluation of insect quality. This study used short-wave infrared (SWIR) hyperspectral imaging to predict the proximate composition of dried BSFL, including moisture, crude protein, crude fat, crude fiber, and crude ash content. The larvae were dried at various temperatures and times, and images were captured using an SWIR camera. A partial least-squares regression (PLSR) model was developed to predict the proximate content. The SWIR-based hyperspectral camera accurately predicted the proximate composition of BSFL from the best preprocessing model; moisture, crude protein, crude fat, crude fiber, and crude ash content were predicted with high accuracy, with R² values of 0.89 or more, and root mean square error of prediction values were within 2%. Among preprocessing methods, mean normalization and max normalization methods were effective in proximate prediction models. Therefore, SWIR-based hyperspectral cameras can be used to create automated quality management systems for BSFL.

This study was performed to provide basic data of Saekso 2 corn kernels. Proximate composition, free sugars, fatty acids and anthocyanin content of Saekso 2 corn kernels were analyzed. Proximate composition of dried Saekso 2 corn kernels were represented 8.84% moisture, 1.44% crude ash, 5.46% crude lipid, 10.31% crude protein. Free sugars composition by HPLC/ELSD showed that sucrose (1.00%), glucose (0.63%), maltose (0.52%), fructose (0.44%) were present. The composition of fatty acids in Saekso 2 corn kernels was analyzed by GC/FID. 11 species of fatty acids were analyzed in Saekso 2 corn kernels. The ratio of saturated fatty acids and unsaturated fatty acids 16.09 : 83.91. Content of linoleic acid was the highest in fatty acids. The total anthocyanin content in Saekso 2 corn kernels was 0.24% by UV/Vis. Anthocyanin components separated and quantified using HPLC/MS/MS. Cyanidin 3-O-glucoside chloride (C-3-G), pelargonidin 3-O-glucoside chloride (Pg-3-G) and peonidin 3-O-glucoside chloride (Pn-3-G) of anthocyanin were analyzed in Saekso 2 corn kernels.

Chemical components of Panax (P) species were compared. p. species used were Korean white ginseng, Korean, Chinese and Japanese red ginseng (P ginseng), American and Canadian ginseng (P. quinquefolium) , and sanchl ginseng (P. notoginseng). No significant difference in the proximate contents was observed among P. species. Ash, crude lipld and total sugar contents in root of P. notoginseng were found to be relatively lower than those of P. ginseng and P. quinquefolium, but the contents of crude protein and crude fiber were similar among those ginsengs. Mineral nutrient con tents showed a little difference among ginseng species. Total nitrogen contents were slightly higher in P. ginseng than P. quinquefolium and P. notoginseng and Fe and Cu were lower in Chinese and Japanese red ginsengs. Kinds and compositions of amino acids were similar but contents of amino acids were different among ginseng species. Total amino acid contents were 76.3∼83.9 mg/g in P. ginseng 53.8∼60.4 mg/g in p. quinquefolium and 54.9 mg/g in P notoginseng. Free sugar contents were lower in P. notoginseng than P. ginseng or P. quinquefolium. Sucrose accounted for 90∼92% of total free sugar contents with relatively high content in white ginsengs, while sucrose and maltose were 32-36% and 55∼60%, respectively, in red ginseng.

The proximate, fatty acid and total amino acid compositions of striped jewfish Stereolepis doederleini muscle were studied. The proximate composition was: 76.4% moisture, 19.4% protein, 2.92% lipid, and 1.19% ash. The predominant total lipid fatty acids were 16:0 (18.7%), 18:1n-9 (16.5%), 22:6n-3 (16.0%), 16:1n-7 (8.53%), 20:5n-3 (7.97%) and 18:0 (5.34%). Glutamic acid (17.4%), lysine (10.6%), aspartic acid (10.4%) and leucine (8.27%) were the predominant amino acids in striped jewfish muscle. These food components of striped jewfish were similar to those of costal and reef dwelling fishes such as black rockfish, black sea bream and rock trout, which are common sliced raw fish in Korea. Therefore, these results suggest that striped jewfish may represent a new aquaculture fish species.

The effect of pan frying method was evaluated for proximate composition of selected fish species Pampus argenteus, Lethrinus nebulosus and Acanthopagarus arabicus which were determined by standard procedures. Proximate compositions found in the frying fillets were different to the raw fish samples. The moisture content seems to decrease in all fried samples. The reason of moisture loss at the time of frying produced is excessive protein amount in fried fish as compare to raw fish. Protein content seemed to increase in Pampus argentus > Lethrinus nebulosus and >Acanthopagrus arabicus in their particular fried form. The outcomes shown that protein content was in the ranges of 14.83-25.07 g/100g in fried samples, while the fat content was between 3.76-9.77 g/100 g. The energy content was the highest in the fried fish Lethrinus nebulosus (236 kcal/100 g), Pampus argentus (161 kcal/100 g) and Acanthopagrus arabicus (135 kcal/100 g). The information achieved in this study would be very important to fish consumers, processors and nutritionists to academically increase their awareness regarding the nutrients contents in selected fish species.

This study was conducted to investigate the relationship between lactational capacity and intakes of energy and energy-yielding nutrients. Food consumption, intakes of carbohydrate, protein, fat and energy and quantity and proximate composition of milk of 11 lactating Korean mothers were determined at 1, 2 and 3 months postpartum longitudinally. Food consumption was estimated using a 24-hour recall method ; intakes of energy and energy-yielding nutrients were calculated according to the Food Composition Table. Daily milk production was estimated using a 72-hour test-weighing method ; protein, fat, lactose and energy concentrations were analyzed. Average intakes of energy and protein were 1974$\pm$386㎉/day and 67.0$\pm$12.3㎉/day, these were 73% and 74% of the Korean Recommended Allowances, respectively. Average milk yield was 720.1$\pm$123.3ml/day containing energy 59.6$\pm$9.5㎉/dl, protein 1.1$\pm$0.1g/dl, fat 2.7$\pm$0.8g/dl, and lactose 6.3$\pm$0.3g/dl. No relationship existed between the intakes of carbohydrate, protein, fat and energy and the quantity and proximate composition of the milk. However, the intakes of energy, carbohydrate and vegetable protein were inversely related to the concentrations of energy and lactose in the milk. This result indicates that lactational capacity may be affected by the other factors excluding intakes of energy and energy-yielding nutrients and a high intake of energy may not guarantee optimal lactational capacity.

This experiment was carried out to investigate the changes in pH, proximate composition, pH, VBN, TBA, minerals, and fatty acid of venison extracts, from three slaughtered deers with 180~210 kg live weight (♀, Elk deer, 28~30 months of age) at 4$^{\circ}C$. Proximate composition was not affected by storage periods. The pH, VBN, and TBA ranged from 4.60~4.62, 13.52~15.75 mg%, and 0.20~0/81mg/kg. respectively. The pH, VBN, and TBA gradually increased during storage period (p<0.050. Among minerals, K, P, Na, Mg, and Ca were major mineral contents and the Ca, mg, Na contents significantly decreased (p<0.05) according to the storage period. The major fatty acid found in venison extracts were oleic acid, palmitic acid, stearic acid, linoleic acid. Oleic acid, linolenic acid, and arachidonic acid decreased during storage, but palmitic acid, heptadeanonic acid, and stearic acid increased during the storage. U/S (unsalturated fatty acid/saturated fatty acid) ratio tended to decrease during the storage.
