  • The objective of this study was to determine the shelf-life effects and residual nitrite contents of mugwort and pine needle extracts addition in emulsified sausage during cold storage. The sausages were of five types: no mugwort and pine needle extracts added (Control), mugwort water extract added (T1), mugwort ethanol extract added (T2), pine needle water extract added (T3), and pine needle ethanol extract added (T4). Each sausage type was tested in triplicate and assigned to one of four storage periods: 0, 10, 20 and 30 days. As storage time increased, the presence of mugwort and pine needle extracts resulted in decreased pH, CIE $L^*$, and residual nitrite value, but increased TBARS (thiobarbituric acid reactive substance) values, and total plate counts (TPC). Values for pH, TBARS, residual nitrite contents and total plate counts were significantly decreased by the addition of mugwort and pine needle extracts compared to the control (P<0.05). Among all treatments, T4 was more (P<0.05) effective in delaying lipid oxidation compared to other treatment groups. In conclusion, this study demonstrates that addition of pine needle ethanol extract to emulsified sausages tended to improve antioxidant and antimicrobial effects and residual nitrite contents during storage than other treatment groups.

  • This study examined antioxidative activities and quality characteristics of noodle produced with the pine needle powder as 0.5, 1.0 and 2.0% (v/v to korean wheat powder). DPPH radical scavenging activity, reducing power, antioxidative activities, tyrosinase inhibitory activity of the solvent fraction extracts increased in a dose-dependent manner. Especially, butanol fraction showed high DPPH radical scavenging activity, reducing power, antioxidative activities and tyrosinase inhibitory activity. The weight, volume, water absorption and turbidity of cooked noodles containing pine needle powder increased as pine needle powders were higher. When the amount of pine needle powder increased, the Hunter L (lightness) and a (redness) value of cooked noodles decreased, but b (yellowness) value increased. The texture of noodle containing pine needle powder have decreased than control using only Korean wheat powder in hardness, cohesiveness, springiness, gumminess and chewiness. The results of sensory evaluation of cooked noodles containing pine needle powder indicated that the cooked noodles with 1.0% pine needle powder showed the highest value.

  • Distribution of pine needle gall midge infestations was analyzed from data collected in young Japanese red pine stands during 1992, and 1995-1996 in Kangwon-do. No significant differences in percentages of infested needle pairs were found among trees and between terminal and lateral shoots within a tree. However, the mean percentages of infested needle pairs increased significantly from the lower crown to the upper. Percentages of infested needle pairs on sample units, consisting 1 terminal and 2 lateral shoots, in the midcrown were best predictors of whole-tree percentages than were other crown levels. Therefore, a sample unit consisting of 1 terminal shoot and 2 lateral shoots per branch were fixed from the midcrown level. Number of tree and sample unit combinations needed to estimate pine needle gall midge infestations with given two levels of precision were determined.

  • Different masking materials were evaluated for their ability to ameliorate odor of model poultry manure solution by assessing their effects on sensory pleasantness and odor intensity. Results indicated extracts from Eastern red cedar leaves, Loblolly pine needles', and commercial masking agents such as pine extract and odor neutralizer were effective (p<0.05) for masking odor of model poultry manure solution by increasing (p<0.05) pleasantness (82 and 86% increases in pleasantness using red cedar and pine needle extracts, respectively) and decreasing (p<0.05) odor intensity (odor intensity reduction by 66 and 76% using red cedar pine needle extract). The most odor-active compound in Loblolly pine needle extract was ${\alpha}$-terpineol (1,573.8 ug/g) which is responsible for aroma of pine trees (piney) and effective for ameliorating agricultural odors.

  • The effects of pine needle extracts on serum and liver lipid contents were evaluated in rats. Thirty male Sprague-Dawley rats weighing 329$\pm$4 were divided into five groups and fed high fat diets for four weeks. Each group was administered with following pine needle extract: control, water ; WE-3, hot water extract(3% PN) ; WE-6, hot water extract(6% PN) ; AE-3, acetone extract(3% PN) ; AE-6, acetone extract(6% PN). Weight gains were significantly lower in WE-6 group than other groups. But there was no significant difference among other three groups. Intakes of diet and water containing the extract and the weights of liver, kidney, heart and spleen were not significantly different among the groups. The contents of serum and liver triglyceride in the WE-3 group were lower than those of control group. The contents of HDL-cholesterol in serum of the WE-3 group was significantly higher than other groups. The value of risk factor index(RFI) was determined to be low especially in case of WE-3 group. Due to pine needle extract administration, concentration of liver total lipid in WE-3 group was significantly lower than that of the control group. These results suggest that the WE-3 may reduce elevated levels of serum and liver lipid contents in rat fed high fat diet.

  • The removal of volatile organic compounds (VOCs) from water using KOH-activated pine tree needle leaves biochar is considered a cost effective and efficient process. In this study, pine tree needle leaves were mixed with 0, 50, 100 and 200% (KOH weight/feedstock weight) of KOH, respectively. Then, the mixture was pyrolyzed at $500^{\circ}C$ for 6 hrs. The adsorption characteristics of 10 VOCs to the biochar were tested. The results indicated that the removal efficiency of the KOH activated biochar was highest in 100% KOH-biochar. The VOC removal efficiencies of 50% and 200% KOH activated biochar were similar and the 0% KOH activated biochar showed the lowest VOC removal. The FTIR results showed that increasing the amount of KOH seemed to enhance the formation of various functional groups, such as -OH, -C=C, -O. The adsorption strength of 10 VOCs to the KOH activated biochar seemed to be increasing by the increase of the solubility of VOCs. This may suggest that the adsorption is taking place in hydrophilic sites of the biochar surface. The KOH activated pine tree needle leaves biochar can be an effective sorbent for VOCs removal in water and 100% KOH mixing seemed to provide better sorption capacity.

  • The purpose of this study was to evaluate the color image of the natural-dyed silk fabrics. The dye was extracted from pine needle by boiling pine needle with ethanol at $78^{\circ}C$ for 3hours and distilled water at $100^{\circ}C$ for 2hours. The 100% silk fabric was dyed of extract in pH 5 at $90-100^{\circ}C$ for 1 hr. As mordants used were compounds of Al, Sn, Fe, and Cr, color image of pine-needle dyed silk fabrics was classified into 5 factors (pure, gentle, sophisticate, comfortable, pastorale) and the factor pure is most important one of those. Most cheerful image in pure factor was from the fabrics dyed with ethanol extract and then, none and Cr mordanting. Dignified image was from the fabrics dyed with ethanol extract and then, Cu or Fe mordanting. In production, products dyed with ethanol extracts was preferred to those dyed with distilled water extracts. Color image and preference of the silk fabrics dyed with pine needles extracted was affected by extraction solvents and mordants.

  • Polybrominated diphenyl ethers (PBDEs) in pine needles and soil samples from rural area were analyzed in this study. Concentrations of PBDE congeners were ranged between 0.2 and 3104 pg/g DW(dry weight) in pine needles and between 2.4 and 1997 pg/g DW in soil samples. The most abundant congener both in pine needles and soil samples was BDE-209, which was related to importation and production of deca-BDE technical mixtures in Korean industry. And BDE-99, BDE-47, BDE-100 deposited in pine needles and soil samples were closely matched with the major constituents of the penta-BDE technical mixture. Those can be interpreted as an evidence that transfer of the congeners in deca-BDE and penta-BDE technical mixtures from source to pine needle and soil occurs with broadly similar efficiency. Correlation coefficient(r) of PBDE congeners deposited in pine needles and soil samples is very significant because it implies th at there has been little weathering/degradation/alteration of the congeners generated from sources during atmospheric transport or within pine needles and soil themselves.

  • This study investigated the effects of feeding mulberry leaf extracts on lipid composition in rats fed high cholesterol diets. An initial 30-person sensory evaluation of preparations containing various concentrations of mulberry leaf extract showed that a preparation containing 9% mulberry leaf extracts was the most highly preferred. In addition, subsidiary materials of pine needle extracts and mugwort extracts were added to weaken the unpleasant smell of mulberry leaf extract A preparation containing 9% mulberry leaf extract with 3% mugwort extract and 7% pine needle extract was given highest preference scores by the 30-person panel. When comparing the functional ingredients contents of the various preparations of mulberry leaf extracts, such as GABA, DNJ and flavonoids, no significant differences were found as a result of adding subsidiary materials (pine needle and mugwort extracts). Sprague-Dawley male rats weighing l00$\pm$10g were randomly assigned to one normal diet group, and to four high cholesterol diet groups containing 1% cholesterol, to elucidate the functionality of the mulberry leaf extract The four high cholesterol diet groups were classified into: a mulberry leaf extract diet group free of subsidiary materials (EB group); a mulberry extract diet group with pine needle extracts (EP group); a mulberry leaf extract diet group with mugwort extracts (EM group); and a control group (HC group). The mulberry leaf extracts were provided as drinking water; the diet and water were fed ad libitum. Hepatic cholesterol and triglyceride levels were higher, by 279% to 475%, in the high cholesterol groups compared to the normal diet groups, but were significantly lower in the three groups supplied with mulberry leaf extracts, compared with the high cholesterol control. There were no changes in functionality of the mulberry leaf extract preparations due to the addition of subsidiary materials. In conclusion, preparations of mulberry leaf extracts were shown to improve lipid metabolism in rats fed a high cholesterol diet, by reducing hepatic and plasma triglyceride and cholesterol levels. Also human palatability of the mulberry leaf preparation was improved by adding subsidiary materials such as pine needle and mugwort extracts.
