Isolation and Characterization of Mitochondrial DNA from Arehicityars and Metacitrus
The Korean Journal of Food And Nutrition, volume 8, issue 4, 1995, Pages 307~317
The purity of mtDNAs isolated from Archicitrus and Metacitrus leaves was higher in percoll density gradient centrifugation than differential and sucrose density gradient centrifugation. The most clear mtDNAs were obtained from mitochondria included in the Interface band of between 21% and 45% under isomotic, low viscosity conditions in the three step discontinuous percoll density gradient centrifugation. DNase treatment to the crude mitochondrlal suspension still more increased purity of mtDNA by the effective removal of the nuclear and chloroplast DNA and mtDNAs were appeared as a single band at middle position of tube by EtBr /cscl density gradient centrifugation. Agarose gel electrophoresis of mtDNAs resolved a single, broad band containing high molecular weight DNAs In all preparation. Yield of mtDNAs was about 110 and 2 ug Per 2009 in mature and immature leaves respectively. The mtDNA fragment patterns showed by EcoR I treatment were indistinguishable with respect to nom bet and position of bands in Archicitrus and Metacitrus. In the pattern of Hind E restriction, the Metacitrus displayed the unique band between 5.0 and 4.0kb, in addition to four fragments about 5.0, 2.4, 2.15, and 2.0kb, respectively, different from Archicitrus. Also the pattern of total mtDNAs fragment by the treatment of Pst I showed that the distinguishable fragment pat tern was not appeared in Archicitrus(C. iyo Tanaka), but about 6.0, 5.5, 5.0 and 2.Bkb fragments were appeared only in Metacitrus(C. junos Sieb). Therefore it was indicated that two species in intra-subgenus were identical each other, whereas considerable difference was revealed for inter-subgenus.
Effects of Dietary Omega-3 Fatty Fish on Serum Insulin and Glucose in Normal Subjects
The Korean Journal of Food And Nutrition, volume 8, issue 4, 1995, Pages 318~324
The purpose of this study was to Investigate the response of fasting serum glucose and basal insulin to dietary omega-3 fatty fish in normal subjects. Nineteen healthy female volunteer subjects were divided into two groups, depending on fish preference test. Low ap3 fatty acid group for 7 days received a experimental Inlet containing mackeral fish 100g. Calorie intake was 1780 kcal /day. The average 4ally u-3 fatty acid consumption from fish was 3.87g /day (1.03g EPA, 2.849 DHA) . High n-3 fatty acid group was given 7.74g maine u-3 fatty acid (200g mackeral fish) consisting of 2.06g EP45.68g DHA. Calorie intake was 1815 local /day Fasting blond serum glucose, insulin levels were measured at baseline, 7days after experimental diet. In the beginning the levels of fasting serum glucose, basal insulin were not different between both groups. There were no significant changes in fasting serum glucose, insulin levels by experimental diets. These data indicate that marine ar3 fatty acid consumption have no deleterious effect on glycemic control in normal subjects.
A Study of Dried Noodles Prepared from Composite Flours Utilizing Job's Tears and Wheat Flour
The Korean Journal of Food And Nutrition, volume 8, issue 4, 1995, Pages 325~329
To investigate the Possibility of making noodle with Job's tears flour(JTV), it was mixed with wheat flour by the ratio of 60oyo. Making characteristics of noodle was studied in terms of cooking quality test, color measurement and sensory evaluation. The cooking quality of noodles with 10~40% JTF was almost same value as control in weight and volume of cooked noodle. Color difference (
E) between noodles with JFT and control was revealed appreciable value. Though noodles with 10~30% JFT was not significantly different from control in color, only noodle with 10% JFT was same as control In texture by sensory evaluation test.
Influence of Cultivar on Rice Cooking Properties
The Korean Journal of Food And Nutrition, volume 8, issue 4, 1995, Pages 330~334
A various aseptic packaged cooked rice prepared In Korean rice was developed for extending shelf-life at room temperature. Data of proximate composition showed no significant difference between cultivars except moisture of cooked rice. The optimal condition of added water content for aseptic packaged cooked rice was 1.3 times of rice while 1.5 times for cooked rice and microwave heating. Hardeness of cooked rice was decreased in order of Dongjin, Odae, Chuchung, Kyaehwa, Ilpoom. Sensory evaluation results showed that Ilpoom had a best result while Odae for storage time (7 days).
Preparation of Pronase Hydrolysate from Alaska-pollack
The Korean Journal of Food And Nutrition, volume 8, issue 4, 1995, Pages 335~343
In order to enhance the utility of alaska-pollack, the optimum conditions for the preparation of pronase hydrolysate. The optimum temperature and pH for the hydrolysis of alaska-pollack by pronase were 4
and pH 7.0. The reaction time and enzyme concentration were 4 hr and 1,000 units per g of substrate. Under the above optimum conditions alaska-pollack was hydrolysed by pronase yielding a hydrolytic degree of about 89eye. The bitterness and hyrophobicity of pronase hydrolysate were decreased with increasing reaction time. Hydrophobic amino acids(Tyr, Met, Ala, flu, Leu, and Phe) were increased for 2 hr, but fur thor hydrolysis was showed decrease of hydrophobic amino acids content. Palatable amino acids (Asp, Glu, Pro, Ser, Thr and Gly) were increased with hydrolysis time.
