  • The effects of vegetable oils addition on the quality characteristic of pound cake were investigated. The volume of pound cake prepared by adding vegetable oils increased from 1005.8 to 1075.8 mL, compared to 752.8 mL for the control. The volume index of pound cake prepared by adding vegetable oils increased by 3.46${\sim}$3.65, compared to 2.88 for the control. The hardness and penetration of pound cake with added vegetable oils were decreased significantly compared to those of the control during storage for 72 hours. The texture of pound cake with added vegetable oils was not decreased compared to that of the control. The lightness and yellowness values of the cake increased and the redness values of the cake decreased by adding vegetable oils compared to those of the control. The sensory quality of the pound cake with added vegetable oils, as estimated by color, taste, moistness and overall acceptability, was better than that of the control.

  • To obtain basic da1a on the preparation of Cudrania tricuspidata leaves tea, the quality and anti-oxidative characteristics of dried raw leaves (RT), pan-fired leaves tea (PT) and fermented leaves tea (FT) were investigated. General characteristics of RT, PT and FT, respectively, were: moisture content 18.47, 6.23 and 8.50%; crude protein content 17.77, 20.46 and 19.13%; and carbohydrate content 54.42, 62.52 and 61.96%. The crude lipid and ash contents were in the range 0.05 - 0.07% and 9.27 -10.74% respectively; the water soluble solid content was in the order FT > PT > RT and ranged from 23.10 - 37.38%; there were no significant differences in the total polyphenol content (815.24 - 835.16 mg%). Although $L^*$ values of PT (20.94) and FT (20.85) were lower than those of RT (34.71), the $a^*$ value in PT and the $b^*$ value in FT were highest. In all ethanol extracts the reducing power, electron-donating ability and superoxide dismutase (SOD)-like activity increased in a concentration-dependent manner. Furthermore, the activity in FT was higher than in PT or RT. The total free amino-acid content was higher in FT (1429.93 mg%) than RT (1108.94 mg%) or PT (833.13 mg%). The major amino acids were L-asparagine and L-valine in RT, L-cysteine and L-glutamic acid in PT and L-proline in FT. In a sensory evaluation of PT and FT, bitter and astringent tastes were decreased relative to RT, while sweet and savory tastes, flavor, color and overall acceptability were increased. These results indicate that FT bas a higher antioxidant effect and free-amino-acid content than PT, while the sensory quality of FT is similar to that of PT.

  • The effects tea beverages (TBs) prepared from powdered green tea (Gt), oolong tea (Ot), black tea (Bt), or pure tea (Pt) with lemon, orange, grenadine etc on cadmium toxicity in rats were investigated Sensory evaluations of the TBs are better than those of each water extracted teas. Cadmium (50 ppm) was administered to experimental rats fed a basic diet, or a diet with various TBs (15% w/v), for 5 weeks. Although body weight gains, feed intakes, and fecal weights in all Cd-treated groups were lower than those in the normal control group (NC), feed efficiency ratio, urine volumes, liver weights, and kidney weights did not differ significantly between groups. The serum ALT and AST levels in the Cd-treated control group (Cd-Co) were higher than those in the NC animals. Serum ALT and AST levels in all Cd-treated rats fed TB-supplemented diets were lower than in animals of the Cd-Co group. Tibia and femur weights in Cd-Co animals were lower than those in NC rats. Tibia and femur weights in Cd-treated rats fed TB-supplemented diets were higher than those in Cd-Co animals. There were no between-group differences in tibia lengths; animals in the NC and TB-supplemented diet groups showed femur lengths longer than those of Cd-Co rats. Although the contents of crude ash and cadmium in the femurs of Cd-Co mts was markedly higher than in the femurs of NC animals, the cadmium content in femurs of Cd-Co rats was significantly lower than that in the femurs of NC animals. The changes in mineral levels caused by Cd administration were alleviated by every TB-supplemented diet tested Whereas fecal calcium excretion by Cd-Co animals was significantly higher than that of NC rats, calcium excretion by Cd-treated rats fed TB-supplemented diets was significantly lower than that of Cd-Co animals. Fecal cadmium excretion by all Cd-treated rats fed TB-supplemented diets was significantly higher than that of Cd-Co animals. In conclusion, this study provides experimental evidence that various TBs may regulate cadmium-induced organ toxicity by reducing cadmium accumulation in tissues through the mechanism of increasing the fecal excretion of cadmium.

  • We investigated blueberry wine made using traditional yeast (Saccharomyces cerevisiae M-5) and Saccharomyces cerevisiae Fermivin which is widely used in wine manufacturing, and measured its fermentative characteristics and antioxidant activity. S. cerevisiae M-5 is a traditional yeast isolated from domestically grown Black raspberry (Rubus occidentalis). Both S. cerevisiae M-5 and Fermivin were inoculated into blueberry juice (BBJ) up to $1{\times}10^9CFU/kg$, followed by incubation at $25^{\circ}C$ for 39 days. Final fermentation products of blueberry fermented with S. cerevisiae M-5 (BBM) presented 13.10% alcohol, $8.42^{\circ}Bx$ of sugar, and 1.183% acidity, and final fermentation products of blueberry fermented with Fermivin (BBF) presented 14.20% alcohol, $8.2^{\circ}Bx$ of sugar, and 1.153% acidity. The contents of total polyphenol and flavonoid compounds of BBM were higher than those of BBF and BBJ. DPPH and ABTS radical scavenging activities and reducing power of BBM were higher than those of BBF. The sensory evaluation revealed that BBM showed excellent flavor, taste, and overall acceptability compared with BBF. Based on these results, the possibility of industrial utilization of S. cerevisiae M-5 as traditional yeast was confirmed by sensory evaluation and antioxidant activity. Fermentation rate of S. cerevisiae M-5 was similar to Fermivin, which is used in the food industry.

  • This study was conducted to investigate the effects of domestic clay minerals on feed efficiency, meat quantity, meat quality and economic traits in 24 head of Hanwoo steers(166.1kg in body weight) for 540 days from six to 24 months in age. Feeding trial was conducted with 4 treatment(six heads/treatment) which were T1(Control), T2(Control+Kaolinite), T3(Control+Bentonite), T4(Control+Illite). The results obtained are summarized as follows; The range of average daily gains were 0.682 to 0.713, 0.669 to 0.714, 0.690 to 0.840 and 0.699 to 0.756kg in growing, fattening, finishing and over-all period, respectively, and the gains were high in T1 for growing and fattening period but in clay mineral groups for finishing and over-all period, especially it was high in Illite and Bentonite groups. Concentrates and TDN intakes per unit of kg gains were lower in clay mineral groups than in control and was lower especially in Bentonite groups. In carcass characteristics, dressed carcass and fresh meat and retailed cut percent were not apparently difference by treatments, and yield index was 69.3, 68.9, 68.8 and 68.6 in T3, T2, T4 and T1, respectively. Marbling scores were 5.1, 4.6, 4.4 and 3.3 in T3, T2, T4 and T1, respectively, and the range of shear force by treatment was from 3.51 to 6.02kg/cm2. and were improved with significant difference(P<0.05) in clay mineral groups than in control. Also in palatability traits, panel test scores of juiciness, tenderness and flavor were improved in clay mineral feeding groups, especially the flavor was improved with highly significant difference(P<0.01) in clay mineral groups than in control. In total fatty acid contents, the rate of SFA(saturated fatty acid) in longissimus muscle of beef was higher in the order of T2, T3, T1 and T4 while the rate of MUFA(monounsaturated fatty acid) was high in the order of T4, T3, T1 and T2. The content of oleic acid which is major influential factor at the flavor of beef was higher in Illite groups than in any other groups. In composition of amino acids in longissimus muscles of beef, the rate of essential amino acids was high in the order of T1, T2, T3 and T4. and the rate of amino acids in clay mineral groups was smaller than in control.In chemical component in Gom-Tang(soup of bone) made by Hanwoo steer’s leg-bone, the ranges of crude protein, ether extract, and crude ash was 0.81 to 1.24, 0.17 to 0.35 and 0.07 to 0.09%, respectively. In mineral composition, the ranges of Ca, P, Na and Mg was 14.01 to 15.77, 11.45 to 16.40, 37.92 to 49.99 and 0.26 to 0.46ppm, respectively. Chemical composition were not apparently different but mineral composition was increased in clay mineral groups than in control. Income by treatments was 967,096 to 1,524,055 Won per head for 540 days and income of clay mineral groups in comparison with control’s increased by 23.7 to 57.6 percent, and especially it was higher in bentonite and(or) Illite groups than others. According to the above results it may be concluded that clay mineral to growing-fattening Hanwoo steers can be improved the meat quantity, meat quality and income. Especially the effect of bentonite and illite is large and can be recommended for usage to improve animal performance as feed additives of growing-fattening Hanwoo steers.

  • The diagnosis in Oriental medicine is done by inspection, auscultation and olfaction, interrogation, four diagnostics of pulse feeling and palpation, and various system of identification like identification according to Qi(vital energy), Xue and body fluids, identification according to fair principles, identification according to principles of Wei, Qi, Ying and Xue, identification according to Sanjiao(the triple heater), identification according to four type physical constitution. Sometimes, symptoms and diagnosis techniques according to symptoms is selectively applied for the diagnosis. Among them the pulse feeling and palpation diagnosis technique using the sense of finger and palm of the hand is divided into feeling of pulse and palpation and pressing maneuver. Pressing maneuver is a diagnosis technique pressing and rubbing the affected part in order to attain data of identification including inside and outside condition of the body with regard to the nature, condition and relative seriousness of disease. There are palpation of the skin, palpation the hand and foot, palpation the chest and the abdomen, palpation shu points in pressing maneuver. The diagnosis of the Back Shu points is a technique to examine the change of disease condition from pressure ache, spontaneous ache, tension, relaxation, solidification revealed through channels and collaterals. I investigates starting disease and an attack of disease of twelve pulse and pulse condition through the study relative to the substance and technique of pressing maneuver, and adjusts diagnosis techniques of a region for acupuncture and matters to be attended. The conclusions are as follows. 1. The Shu or stream points in which pathogenic factors go are important to medical treatment of dormant diseases like bowels disease, cold symptom complex and insufficiency symptom complex. 2. Disease classified by system is diagnosed by the condition of process part like pro-trusion, cave-in, tension, relaxation, pressure ache through palpating the Shu or stream points, that is pressing upward or downward left and right sides of the backbone process by hands. 3. In real clinic pressing maneuver of one's back side is very important to patient's diagnosis treatment. Thus, pressing maneuver of one's back side have to be done without omission. 4. Diagnosis must be accomplished through the perception about the diversity of diagnosis technique of bowels disease, the exact knowledge about pressing maneuver of one's back side for enlargement of treatment range and rising of treatment rate, and pressing maneuver of the Shu or the stream points.

  • Pork cutlet is a favorite deep fat fried food item among Korean children, and an excellent protein-containing food, and as well as a simple and economical cuisine. However, the frying process adds a significant amount of calories. We added MC (Methylcellulose) and HPMC (Hydroxypropyl Methylcellulose) to the batter in an effort to reduce oil uptake in prepared pork cutlets. After additions of MC and HPMC at concentrations of 0.5, 1, and 1.5% respectively, we assessed the viscosity of batter, color after frying, the increases in moisture retention and oil uptake, and sensory characteristics, comparing each quality. The viscosity of batter with 0.5% HPMC added (w/w) was similar to that of the controls, but the viscosity of all the batter with added MC was so much higher that it was difficult to use the batter for coating at the same temperature, leading to a failure even to prepare a sample. After frying, the batter with added HPMC provided significantly less oil uptake and more moisture retention than the batter to which MC was added. Additionally, with regard to color and sensory characteristics, the pork cutlet with 0.5% added HPMC was superior to the other samples. According to these results, we concluded that when cellulose derivatives are added in order to reduce oil uptake and to raise the moisture retention of the batter of pork cutlet, HPMC is more useful in this regard than MC. Additionally, the batter with 0.5% HPMC added appears to be the best of the tested choices, for three reasons: first, the viscosity of the batter is similar to that of the controls; second, the taste is not greasy after frying as the result of the reduced oil uptake and higher moisture retention; and third, the sensory characteristics of this sample, such as, color, crispiness, and hardness were the best among samples.
