Purpose: The purpose of this study was to determine the quality characteristics of gluten-free frying pre-mix with insoluble dietary fiber powder (IDFP) from Chinese cabbage by-product. Methods: Frying powder mix was prepared with 0.5, 1.0, 1.5 or 2.0% IDFP. Fried powder mix only whit brown rice powder was used as a control. Spreadability, pick-up ratio and color of batter, texture, moisture and oil contents, oil absorption and sensory evaluation of fried sweet potato were determined. Results: L and a-values of batter decreased with increasing amount of IDFP, whereas b-value increased with IDFP addition. Hardness and crispiness of fried sweet potato increased with IDFP addition until 1.5%. Moisture content of fried sweet potato increased with higher IDFP addition whereas oil content and oil absorption decreased with increasing amount of IDFP. Sensory evaluation of fried sweet potato showed the best results in the 0.5% of IDFP addition group. Conclusion: Overall preference of IDFP samples was significantly higher than that of control. Based on the study, the optimal amount of IDFP for gluten-free fried powder mix was determined to be 0.5-1.5%.

The purpose of this study is to develop a method to cultivate lactic acid bacteria (LAB) as a by-product in the fermentation of kimchi through the use of Chinese cabbage leaves. A method to reduce the initial number of microorganisms using citric acid and ethanol to wash cabbage leaves was investigated. In this experiment, Chinese cabbage leaves were washed using a mixture of 3% citric acid and 7% ethanol and the washed cabbage leaves were juiced and used as a sample. The total microorganisms of kimchi cabbage juice (KCJ) was reduced from log 6.53 CFU/g to log 3.69 CFU/g by washing with citric acid and ethanol, and lactic acid bacteria from log 4.40 CFU/g to log 2.01 CFU/g. The salinity of KCJ was appropriate for the growth of lactic acid bacteria but the pH was too low. The yield of washing, juice extraction, and total were 80.82%, 79.32%, and 64.11%, respectively. KCJ made by washing with citric acid and ethanol was good for the culture broth of lactic acid bacteria.

The fermentation and quality characteristics of Cheonggukjang with Chinese cabbage, which is produced as a by-product in the kimchi industry, were investigated. Cheonggukjang was prepared with cooked soybean without Chinese cabbage (control), with 10% Chinese cabbage (A10), and with 20% Chinese cabbage (A20), respectively. The A10 and A20 pH values did not show a significant difference compared with the control during fermentation for 72 h. The total aerobes of the Cheonggukjangs reached 8.65 (control), 8.73 (A10), and 9.11 (A20) log CFU/mL after fermentation for 72 h at $37^{\circ}C$, respectively. The numbers of lactic acid bacteria were found to be 5.62 (A10) and 5.87 (A20) log CFU/mL during fermentation for 72 h at $37^{\circ}C$, but lactic acid bacteria were not detected in the control. The amino nitrogen and viscous substance contents of A10 and A20 were lower than those of the control. The total polyphenol contents and DPPH radical scavenging abilities of the tested Cheonggukjang were increased by fermentation. The increasing ratio of polyphenol and the DPPH radical scavenging ability of A10 were higher than those of the control and of A20. The sensory quality of A10 was higher than that of the control and of A20 in taste, color, and overall acceptability.

It is possible to use pallet for forwarding as chinese cabbages and radishes are general large-scale trading items at the agricultural wholesale market though, however, most of these are forwarded as it have packed in net bags or in P·E bags. Thus, it is still hard for palletizing. The type of packing the product in the net bag makes it difficult for palletizing. It is not a stable shape enough and easily collapsed for pallet loading. Because of this collapsibility, the corrugated cardboard box is being used to enhance forwarding efficiency, but the existing corrugated cardboard box could be crushed easily by moist what is from the agricultural product's property and it also could be squashed by the mass of the loaded box layers on itself. In contrary, the functional waterproof corrugated cardboard box is not collapsed through palletizing and it is efficient for product management with it's ventilation function in respond to pre-cooling effect. Furthermore, because it has various functional shapes as the open type, the partition type and so on, it is effective for maintaining freshness of the product and standardizing the distribution of agricultural product. It is well-known that it is possible to introduce this box to cargo-works of agricultural product. Consequently, the recognition of main distributors about the pallet distribution of the chinese cabbage and the radish was apprehended in this study for activating mechanization of loading and unloading. The survey was conducted to the main distributors such as the forwarder, the auction dealer and the commission merchant with Garak-dong wholesale market as the center. The appropriate packing materials and problems of the existing method for loading and unloading were derived through the survey. Especially, it was focused on analyzing the difference of recognition between the subject groups for the way of using waterproof cardboard corrugated box to deal with the difficult product for packing in normal corrugated box because of the box's absorption of moist from the agricultural product like a chinese cabbage and a radish. Total In the cases of the forwarders and the commission merchants, the net was highly responded as 45%, 74% from each groups for the best packing material for mechanization of distribution and the waterproof corrugated cardboard box was responded as 20%, 22% from each groups as much preferable than multi-stage wooden box. However, for the radish, the waterproof corrugated cardboard box was the best material as 56%, and the auction trader group supported it for 80%. So, the using the waterproof corrugated cardboard box for mechanization of distribution was negative for the chinese cabbage, but it was positive for the radish. The average was 2.42, the standard deviation was 1.24. The negative response(about 55%) was prevailing more than positive response(about 23%). It could be analyzed that even there was the positive recognition for using the waterproof corrugated cardboard box for the radish though the preference for low price of net bag in the chinese cabbage forwarding procedure. Still now, it seems that is a burden for using the waterproof corrugated cardboard box with high price. In the analysis on the recognition differences about using the waterproof corrugated cardboard box for the chinese cabbages and the radish between the forwarders and the commission merchants, generally the negative recognition was prevailing, but the forwarders(2.696) were more positive for using the waterproof corrugated cardboard box than the commission merchants(2.145).

Many cloning vectors in which cDNAs can be inserted to the sense orientation have been developed. Uni-ZAP XR vector (Stratagene) should contain clones that are oriented to sense direction with respect to T3 RNA polymerase primer. Unexpectedly, large portions of cDNAs in Chinese cabbage cDNA library showed unusual insertions, antisense orientation and a hybrid of two different clones. Using two clones, 4H03 and 53-B10, derived from different cDNA libraries, we proposed and demonstrated the possibility of unusual-construct formation by in vitro translation and northern blot analysis. The 4H03 clone was inserted with inverse direction, and its transcript and translation product could be produced by T7 RNA polymerase, indicating that this clone is definitely inserted into inverse orientation. The 53-B10 that contains two independent genes was turned out to be a hybrid in which two genes are inserted to opposite direction each other. All unusual constructs might be due to the presence of small fragments of DNA, like adapter. However, the mechanism underlined the formation of unusual constructs is still remain to be solved.

This study was conducted to investigate the effect of homogenized kimchi product (HKP) on dough characteristics and quality of bread. Fermented homogenized Chinese cabbage kimchi product was added 0.10, 20 and 30% to wheat flour. The pH of dough decreased with an increase in the amounts of HKP, which showed at PH 4.9 for the dough added 30% HKP. Fermentation time of the dough was reduced as much as 9~23 minutes as compared with the control products. Loaf volume index of the bread prepared by adding 10 ~30% HKP increased also by 12.7 ~ 19.0%. Hardness, cohesiveness, springiness and gumminess of the bread added with 30% HKP were lower than those of the control. The gas forming cell of the bread added with 30% HKP were good and regular. Crust and internal color of the bread with more HKP had tendency to redness. Sensory quality of the kimchi-bread estimated by shape, flavor and overall quality was better than that of control product, especially the kimchi-bread qualify at addition of 30% HKP was best.

This study was conducted to evaluate the properties of mixtures of mixed organic fertilizer (MOF) and various organic sources such as livestock manure compost (LMC), dried compost of poultry manure (CPM), dried food waste powder (FWP) and amino acid by-product fertilizer (ABF) and their influences on growth of lettuce and Chinese cabbage. The content of N, P2O5 and K2O of mixture of MOF, LMC and FWP (MLF) was 3.6~3.9%, 2.1~2.2% and 1.3~1.4%, respectively. Lettuce dry weight of MLF3 treatment blending with MOF (60%), LMC (10%) and FWP (30%) was increased by about 29% than that of MOF. The content of N, P2O5 and K2O of mixture of MOF, CPM, FWP and ABF (MCFA) was 4.5~4.7%, 1.7~1.9% and 1.3~1.4%, respectively. Compared to MOF, growth factors of lettuce and Chinese cabbage in the MCFA treatments were not significantly deferent. These results indicated that MLFs and MCFAs, the mixtures of respectively organic sources and MOF, could be applied as orgnic fertilizer in the cultivation of lettuce and Chinese cabbage, and were expected that LMC and ABF might be used as another sources of organic fertilizer.
