  • An analysis of changes in herbal tea composition according to the difference in processing conditions showed slightly reduced crude protein content and increased, moisture, crude fat and solid elution rate after treatment using the ash puffing process compared to roasting. Benzopyrene content was significantly reduced to 0.18 ppb from 0.51 ppb. This result indicated that, the $B({\alpha})P$ content differed depending on the processing condition and raw materials. Generation of food $B({\alpha})P$ is mainly include the thermal decomposition of food cooking, when the processing which is a main component of food carbohydrate, protein, fat reason despite severe heat treatment as a whole is to be detected even though the $B({\alpha})P$ in this way is considered to be. The taste, aroma and color did not show a large difference, but the strong bitters taste decreased.

  • Lycium barbarum extract has a high potential to be developed as a health functional food due to the various health-promoting effects of Lycium barbarum. This study analyzed changes in nutritional and functional components depending on the extraction solvent (purified water and a mixture of purified water and alcohol) and the condition of the sample. The nutritional components (carbohydrates, protein, fat, ash), organic acids, amino acids, total phenolic compounds, and total flavonoids of the extract produced during the extraction process were analyzed. The nutritional composition and functional substances of the extracts showed some differences depending on the type of solvent and the condition of the sample. The amounts of crude protein (7.61%), crude fat (1.63%), carbohydrate (90.22%), and ash (0.54%) of dried Lycium barbarum extract using purified water as a solvent were similar to those of the powder sample extract. The highest content of citric acid was 4.31 mg/mL, similar to the case of acetic acid, when the powder sample used a mixture of purified water and alcohol as a solvent. The highest amino acid content was 357.39 mg/mL when the powder sample was mixed with purified water and alcohol as a solvent. The total amount of phenolic compounds was 686.16 g/L when the powder sample was extracted with a mixture of purified water and alcohol as a solvent. The highest total flavonoid content was 111.32 g/L when the powder sample was extracted with a mixture of purified water and alcohol as a solvent.

  • The experiment was conducted to investigate the physico-chemical characteristics of vacuum and aerobically packed meat from Elk deer weighing 170 $\pm$ 10kg of 28 to 30 months old, chilled at 4$^{\circ}C$for 10days. The moisture content, crude protein, crude fat and crude ash in deer loin were 74.46%, 22.11%, 1.27% and 1.13%: the leg parts had 75.47%, 22.68%, 1.58% and 1.27%, respectively. The decrease in moisture content was greater in aerobic packaging than in vacuum packaging. The lysine content of loin and leg parts were 2,380mg% and 2,270mg% and the glutamate content of loin and leg parts were 4,145mg% and 3,987.5mg% respectively. On the whole, the loin contained more amino acids than leg part. Of the mineral contents, phosphorus, potassium and sodium were present in large amounts and mineral content was decreased with longer chilling period. The leg parts contained more potassium, sodium, phosphorus, zinc, magnesium and calcium than loin parts. In conclusion, vacuum packaging is considered more advantageous in preventing meat color change and microbial deterioration for consumers interest.

The purpose of this study was to investigate the chemical composition of Mongolian sea-buckthorn fruits. In terms of proximate composition, crude fat content was the highest, whereas its crude ash content was the lowest. In organic acid contents, malic acid content ($6.30{\pm}0.005$ mg/g) was the highest. Free sugars were composed of sucrose, xylose, glucose and mannitol. Vitamin C and carotenoid content were 320 mg/100 g and 715.25 mg/100 g, respectively. The major fatty acids were palmitic (C16:0), palmitoleic (C16:1), caprylic (C8:0) and linoleic (C18:2) acid.

Crude fat of the BFH was lower, but crude protein and crude ash of the BFH were significantly higher than those of the BF and the BI. Among the minerals, Ca, p, Mg, Fe, Cu, Zn content of the BFH were significantly higher than the content in the BF and the BI. The minerals, Pb, Cd and As were not detected in ostrich and herb medicine extracts. From the sensory test of ostrich and herb medicine, the preferences were in the fellowing order; ostrich bone with flesh meat with herb medicine (BFH), ostrich bone with flesh meat (BF), and ostrich bone with internal organs (BI) in extracts.

  • In this study, Jeolpyon(imprinted with flow patterns) was prepared with different amount of added Astragalus membranaceu extracts(0%, 3%, 6%, 9% and l2%)and then the quality and sensory characteristic effects were examined. All togather the chemical composition of the samples was as follows: $53.l2{\pm}0.04%$ of moisture, $l4.43{\pm}0.05$ crude protein, $7.6l{\pm}0.11%$ crude fat, and $21.35{\pm}0.09%$ crude ash. Hardness and cohesiveness significantly increased(p <0.001), and springiness, chewiness and adhesiveness decreased, with increasing amounts of Astragalus membranaceus extract. In the chromaticity analysis, the L-value(brightness)significantly decreased with increasing Astragalus membranaceus extract content, and the b-value(yellowness) increased in direct proportion to the extract content. Finally, in the sensory evaluation, the Jeolpyon containing 9.0% extract received the highest overall preference scores.

  • Purpose: This study was aimed to compare the nutritional content of the life stages of Tenebrio molitor. Methods: Nutritional element analysis comprised 12 minerals, 18 amino acids, 4 vitamins, and 12 fatty acids in larval, pupal, and adult stages. Nutritional element content was expressed as a percentage of 100 g of sample and determined in raw and freeze-dried samples to assess the food value of the insect. Results: Moisture, crude protein, and crude fat contents in raw samples were 63.5%, 23.19%, and 3.96%, respectively. Moisture content was significantly higher in the adult stage than in larval and pupal stages, whereas crude fat and crude ash contents were lower. Mineral composition of the mealworm showed K, P, and Mg in decreasing order of content, with no differences among life stages. Total amino acid content increased from adult, pupal to larval stages, in order with each stage's growth, without difference in amino acid composition. Seventy-six to 78% of total fatty acid corresponded to unsaturated fatty acids, with oleic acid as the most abundant. In addition, fatty acid content was high in the adult stage, and clear differences were observed between life stages. Finally, vitamins B1 and B3 showed similar content between life stages, whereas vitamin B2 showed a higher content the adult than larval and pupal stages. A higher folate content was observed in pupal and adult stages than in the larval stage. Although freeze-dried samples showed a higher nutritional content than raw samples, both samples were similar in composition and content between life stages, suggesting the suitability of freeze-dried samples for use as food materials. Conclusion: These results may provide a basis for more diversified industrial applications of the Tenebrio molitor.
