  • The esterification of alcohols with acetic acid, lactic acid and citric acid was carried out in batch during the second distillation. Effect of various parameters, e.g. pH of reactant base spirit, temperature of distillation, time of distillation were studied. The parameter of distillation temperature was modified by atmospheric distillation and pressure distillation. The pressure(1.9 atm.) distillation was used in order to react and distill at high temperature. Compared with the base spirit concentration, ethyl acetate, ethyl lactate and iso-amyl acetate in esterification distillate increased by 2,890%, 6,410% and 52%, respectively. Major factors of the esterification with organic acids in distilled spirit making were molecular weight of the organic acid and pH of reactant base spirit.

  • This study was carried out to investigate physical and chemical characteristics of the distillates and residue of Athabasca oilsand bitumen obtained from Canada, using a vacuum distillation unit. The distillates and residue produced from the vacuum distillation were characterized through atomic analysis, SARA analysis, and measurement of boiling point distribution, molecular weight, and API gravity. The vacuum distillation equipment consisted of a 6-litter volume vessel, a glass-packed column, a condenser, a reflux device, a flask fer collecting distillates, and a temperature controller. The cutting of distillates was performed with four steps under the condition of full vacuum and maximum temperature of $320^{\circ}C$. The results showed that the sulfur amount and average molecular weight of the distillates were significantly reduced compared to those of oilsand bitumen. As the cutting temperature increased, the hydrogen amount decreased but the sulfur amount and average molecular weight increased in the distillates.

  • Pork cutlets containing ginseng powder 1% + ginseng distillate 1%(P1/D1), ginseng powder 2%(P2), ginseng powder 1.5% + ginseng distillate 1.5%(P1.5/D1.5) and ginseng powder 3%(P3) were manufactured and compared with the control(no ginseng powder and distillates) in meat quality, sensory evaluation and flavor intensity. The L values were significantly lower and a values were significantly higher for pork cutlets containing ginseng additives as compared to the control. The pork cutlets containing ginseng powder and distillates were higher in hardness only at the beginning stage, but no significant differences in springness, cohesiveness and chewiness among the treatments were observed during storage at -20$^{\circ}C$ for 8 weeks. Flavor analysis indicated that spathulenol, panasinsanol, neointermedol and ginsenol were responsible for ginseng flavor. The sensory panels detected most intense ginseng flavor and taste for pork cutlet which contained combination mixtures of ginseng powder 1.5% and distillate 1.5%. In conclusion, sensory panels evaluated that ginseng distillates produced intense ginseng flavor and enhanced ginseng flavor when used as mixtures with ginseng powder. Therefore, ginseng distillates can be used as a natural antioxidant and flavor enhancer in pork products.

  • To evaluate whether chaff vinegar liquor (CVL) has potential in ameliorating allergic symptoms in mice, we tested the anti-allergic activities with a DNFB (dinitrofluorobenzene)-induced allergic mouse model. The DNFB-induced allergic symptoms were reduced by 20% compared to the control by chaff vinegar liquor supplemented with Perilla frutescens var. acuta. Allergic symptoms were examined by measuring the width of epidermis swelling. The hematoxyline & eosin (H&E) staining also revealed that the chaff vinegar liquor dramatically decreased the allergic symptoms in the epidermis of the ear. These results collectively suggest that the chaff vinegar liquor supplemented with P. frutescens var. acuta has potential in ameliorating allergic symptoms, showing that the liquor could be a useful biomaterial(s) for the nutraceutical or cosmetic industries.

  • This study was performed to examine the cytotoxic effects of the distilled pine-needle extracts against several cancer cell lines. First, cell lines including mice leukemic cancer cell line (L1210), sarcoma 180 and human monocyte-like cancer cells (U937) were tested using XTT methods in uitro. Pine-needle extracts were prepared by pressing the pine needles and distilling it at below 98$^{\circ}C$ and then added to the growth medium in a final dilution of 10, 20, and 40 times. Growth of three kinds of cancer cells was significantly inhibited by more than 50% with the addition of the extracts. Fifty six to seventy six % of inhibition was shown with the 40 times dilution of the extracts. Greater inhibition was achieved with the 20 times dilution (81~90%) and the 10 times dilution (77~89%) of the extracts. Next, other human cancer cell lines including 3 kinds of breast cancer cell lines (T47D, MDA-MB-231 and MW7A) and one hepatoma cell line (SNU-354) were tested with the 20 times dilution of the extract. T47D and MDA-MB-231 cell lines showed lower inhibition (12%) with the addition of the extract. However, MH7A and SNU-354 cell lines showed 64% and 72% inhibition with the extract, respectively. These results suggest that the distilled pine-needle extracts have strong cytotoxic effect on certain cancer cell lines and the intensity of the effect may vary depending on the process of the pine needle.

  • Purpose: The effects of water extract and distillate from the mixture of black goat meat and medicinal herb on MG-63 osteoblast proliferation and mouse bone marrow derived osteoclast formation were investigated. Methods: Proximate composition, volatile basic nitrogen (VBN), mineral content, free amino acid composition and free fatty acid composition in black goat meat were determined. Water extract and distillate were prepared with three groups; goat meat only (BG-E, BG-D), six herbs added group (BG-E6, BG-D6), and eight herbs added group (BG-E8, BG-D8). Osteoblast proliferation, mineralization and calcium uptake activity of MG-63 cells were measured and tartrate resistant acid phosphatase activity of osteoclasts was analyzed. Results: Black goat meat had remarkably low fat and high level of calcium. Glutamic acid was the most abundant amino acid. Herbs added extract groups (BG-E6 and BG-E8) showed increased MG-63 cell proliferation in a concentration dependent manner, while all the distillates did not show the effect. All extracts and distillates showed significantly increased osteoblast mineralization depending on the concentration. In particular, herb added extract, BG-E6, increased 170.3% of control and the distillate of BG-D and BG-D6 increased up to 168.5% and 159.8%, respectively. Calcium uptake activities of all water extracts showed remarkable increase of BG-E6 and BG-E8 up to 615.5% and 628.1% of control, respectively. Ditillates had no effect except BG-D6. All water extracts significantly reduced the activity of tartrate-resistant acid phosphatase (TRAP) in osteoclasts derived from mouse bone marrow. Conclusion: Combination of black goat meat and medicinal herb increased the MG-63 cell proliferation and effectively inhibited osteoclast differentiation in both water extracts and distillate of them, which implies that they could be used as potent functional food materials for bone health.

  • This study was performed to determine the antioxidative, antimutagenic, and anticancer effects of vaporized liquid of water-boiled pine needle(VLP) using DPPH free radical donating method, Ames test, and cytotoxicity. VLP showed the highest electron donating activities $(18.4\;{\mu}L)$. The inhibition rate of VLP $(200\;{\mu}L/plate)$ in the Salmonella. typhimurium TA100 strain showed $45.9\%$ inhibition against the mutagenesis induced by MNNG. In addition, the suppression of with same concentration of VLP in the S. typhimurium TA100 strains showed $85.5\%$ inhibition against 4NQO, respectively. The suppressions under the same condition against Trp-P-1 in the TA98 and TA100 strains were $91.0\%$ and $62.1\%$, respectively. The cytotoxic effects of VLP against the cell lines with human lung carcinoma (A549), human hepatocellular carcinoma (HepG2) , human gastric carcinoma (AGS), human breast adenocarcinoma (MCF-7) and human cervical adenocarcinoma (HeLa) were inhibited with increase of the VLP concentration. The treatment of $50\;{\mu}L/well$ VLP showed strong cytotoxicities of $78.7\%,\;90.3\%,\;90.8\%,\;62.3\%$ and $93.7\%$ against A549, HepG2, AGS, MCF-7 and HeLa, respectively.
