  • This study was conducted to improve sensory quality of Jokbal (Korean Pettitoes) made from frozen pig feet by addition of herbal mixture (glasswort, raspberry and Sansa powders). After adding herbal mixture, lipid oxidation (2-thiobarbituric acid values, TBARS), sensory property, and textural property were determined. Herbs were individually added into cooking soup at concentration of 6% (low concentration treatment, LCT) or 12% (high concentration treatment, HCT) of raw pig feet. Refrigerated pig feet were used as control. Thawed feet without any herbal mixture were used as freezing treatment (FT). TBARS in LCT or HCT were lower than that in FT, and showed the similar to that in Control. Addition of the herbal mixture was effective in improving the flavor and textural property of thawed feet by inhibiting lipid oxidation and protein denaturation in a dose-dependent manner.

  • This study was undertaken to investigate the producibility of processed foods utilizing 6 newly developed non-glutinous rice cultivars. First, cooked rice, cake, cookies, bread, and slender rice cake sticks were prepared with the newly developed cultivars; then their physicochemical and textural properties were evaluated. The rice samples had similar pasting temperatures and peak times, but different viscosities and other pasting properties. The textural analysis results suggested that 'Chucheong' was appropriate for cooked rice due to its low amylose content; hardness, and springiness; 'Ilphumbyeo' for rice cakes due to its high amylose content, moderate cohesiveness and adhesiveness, and low hardness; 'Ilphumbyeo' for cookies due to its high amount of protein, and low cohesiveness and adhesiveness; 'Ilphumbyeo' for bread due to its high amylose content, moderate hardness, and low consistency; and 'Ilphumbyeo' for the slender rice cake sticks due to its low hardness, moderate breakdown, paste viscosity, and setback.

  • To find the possibility in utilizing the fish meat processing by-products, protein nutritional quality and textural properties of crucian carp extraction residue (CCER, feeze dired) incorporated into cookies were investigated. Moisture, ash and protein contents in cookies were increased with the higher residue treatments, but lipid contents were similar within all levels (3%, 9% and 15%). Major constitutional amino acids were revealed as glutamic acid, proline, leucine and arginine, and the sum of those amino acids was about 50% of total amino acid contents. Cookies with residue (CCER) had higher (80.74~84.50%) in vitro protein digestibility than standard cookies (83.32%), while slightly lower trypsin indigestible substrate (TIS) contents were showed in CCER containing cookies than control. CCER treatments resulted the decreased protein nutritional quality in C-PER (computed protein efficiency ratio) value from 2.41 (standard) to 1.15 (cinnamon flavored. 9% CCER), and those C-PER of all cookies were lower than ANRC casein (2.50). Lipophilic browning was developed steadily till 60 days storage and a significant (p<0.05) changes of browning ws not noteed between 60 days and 90 days storage. Color of cookies, expressed as L, a and b value, was significantly (p<0.05) lightened with the increased CCER. Similar trends by treatments were noted for hardness. Cookies containing 9% CCER were similar to control regarding textual and sensory properties.

  • Several ingredients of kimchi including chinese cabbage, garlic, leek, big green onion, and small green onion were assayed for their chitinase activities. Kimchi with various leek contents (4, 8, 12%) were fermented at 15$^{\circ}C$ for 9 days and the chitinase (EC 3.2.1.14) activity and textural properties were determined. The chitinase activity of the ingredients was in the order of garlic>leek>small green onion>chinese cabbage>big green onion. During fermentation, the chitinase activity of kimchi juice appeared more prominent than that of kimchr tissue, however, it was decreased in all kimchi samples among which the control sample showed a remarkable drop. The activity of chitinase in kimchi tissue increased until 3rd or 5th day of fermentation and then decreased. The puncture force of all kimchi samples decreased and those of leek-added kimchi were higher than those of control. The above results suggested that the addition of leek for kimchi preparation could contribute to the improvement of textural qualities of kimchi due to chitinase activities of leek during fermentation.

  • Mesoporous carbon CMK-3s with different textural properties have been used for the adsorption of phenol to understand the necessary physicochemical properties of carbon for the efficient removal of phenol from contaminated water. The kinetic constants (both pseudo-second order and pseudo-first-order kinetics) increase with increasing pore size of carbons. The maximum adsorption capacities correlate well with micropore volume compared with surface area or total pore volume even though large pore (meso or macropore) may contribute partly to the adsorption. The pore occupancies also explain the importance of micropore for the phenol adsorption. For efficient removal of phenol, carbon adsorbents should have large micropore volume and wide pore size for high uptake and rapid adsorption, respectively.

  • Effects of storage temperature at 18oC and 5oC for 9 days and heating conditions on textural char acteristics in strong wheat flour gels were investigated using a Instron after microwave (2450MHz, 700W). Heating condition did not affect the texture property in the wheat flour gels, but the frozen storage was very effective to prevent the hardening of the samples. Hardness, adhesiveness, and gumminess in the wheat flour gels decreased in increasing moisture content from 45% to 55%, but there was little change in cohesiveness. The storage at room temperature for 2 hours resulted in increased hardness in the heated wheat flour gels. PE wrap package of the wheat flour gels prevented weight loss by 3~6% and hardening effectively. Sugar, or sugar and shotening resulted in increased hardness in loaf bread. The hardness and weight loss in loaf breads were markedly changed by the heating time with microwave. The most critical time point was around 4 minutes following the heating.

  • The texture describing terms used for the Korean staple foods, cooked rice, noodles and Kimchi, were surveryed by questionnaire. A total of 154 kinds of terms were collected from 68 answers, in which 95 words were found with definite textural meaning in Korean dictionaries. The terms were classified according to their physical properties by Szczesniak's method. The important textural properties of different types of Korean foods were pointed out by the frequency of mentioning and by the preference expressions. The representative Korean words expressing each textural property of different types of food were selected. The important textural properties for Korean were hardness, brittle-gumminess, chewiness, springiness, adhesiveness, particle size and shape, moisture content and fat content of cooked rice, chewiness, hardness, springiness, and particle size and shape of noodles, and hardness, brittle-gumminess, chewiness, springiness and particle shape and orientation of Kimchi.
