  • 100% root formation in in vitro cultures was observed regardless of kind and levels of auxin used and explant source. The number of roots/explant was increased in 0.5~1.0 mg/L IAA treatment. Thicker roots were observed with the addition of 9% sucrose compared with medium containing lower sucrose concentrations. Paclobutrazol and chlormequat had no effect on tuberization of formed roots but slightly increased the number of root. In in vivo rooting, soaking of regenerated shoot cuttings to 100 mg/L IBA for 15 to 60 minutes was found effective. Treatment of 0.1% IBA rooting powder and planting in rooting medium composred of vermiculite(1) : perlite(1) gave 100% rooting and survival.

  • Energized-functional water (EFW) and powder (EFP) were manufactured by Kyungwon Institute of Life Science, Seoul, through a series of processes; tap water ultra-purification energy imprinting with catalysts in platinum columns mixing energy-imprinted water + activated zeolites + photosynthetic bacteria fermenting at $25^{\circ}C$ filtering EFW and/or EFP. A single application of EFP to soil under tree canopy before bud burst, combined with three EFW applications to soil during growth of 'Fuji' apples (Malus domestica Borkh.) resulted in a higher Ca concentrations in fruit skins and flesh, and lower Ca and N concentrations in leaves and shoot-bark tissues. EFW also stimulated the net photosynthesis of leaves and root activity. Soluble solid concentrations (SSC) and anthocyanin levels of fruits were also significantly increased at harvest, producing greater firmness and less core browning during storage at $0^{\circ}C$. However, there was no significant difference in titratable acidity of fruit juice between the EFW treatment and the controls.

  • According to the statistics of the Ministry of Environment, the amount of food waste generated in Korea is 15,903 tons, which accounts for about 30% of the daily household waste. Food waste in Korea is on the rise, and various odors, greenhouse gases, and leachate generated in the process of discharging, transporting, and processing are emerging as social problems. Accordingly, there is a need for a method for recycling food waste. Therefore, this study was carried out to establish an appropriate limiting dose by manufacturing fertilizer mixed with food waste powder and treating it on tomatoes to investigate the growth and yield of crops. The experiment was carried out with continuous cultivation in 2021 (1st year) and 2022 (2nd year), and the treatment groups were set to No Treatment (NT), Chemical Fertilizer (CF), Mixed Fertilizer (MF), and Mixed Fertilizer×2 (MF×2). As a result of the 1st year growth survey, shoot and root length did not show a significant difference between the treatment groups, and the fresh weight showed a significant difference between the MF and MF×2. As a result of the 2nd year growth survey, there was no significant difference in shoot length, root length, and dry weight between the treatment groups, and the fresh weight of the CF was significantly greater than that of the MF×2. The yield of 1st year, MF×2 increased significantly compared to other treatment groups. In the case of 2nd year, CF, and MF×2 show significantly high values compared to NT. Judging from these results, continuous cultivation using food waste powder mixed fertilizer did not have a significant effect on crop growth and yield. However, it is considered that several studies including continuous cultivation experiments are needed to accurately set the appropriate application amount and limit the application amount of the mixed fertilizer for food waste.

  • This study was conducted to investigate the effects of supplementation of Allium hookeri (AH) root powder on the gut microbiome, immunity, and health in broiler chickens fed experimental diets from d 10 to 28. A total of 60 10-day-old Ross 308 broilers were weighed and assigned to two dietary treatments with 5 birds per cage in a randomized complete block design based on body weight. The two experimental diets consisted of a control diet based on corn-soybean meal and the control diet supplemented with 0.3% AH root powder. All birds were fed ad libitum with experimental diets and water for 18 d. At 28 d, two birds near the median weight from each cage were selected for cecal content and small intestinal tissue sample collection. The addition of AH changed the gut microbiome by increasing probiotic candidate beneficial bacteria such as Enterococcaceae, Lactobacillaceae, Limosilactobacillus, Cuneatibacter, and Ruminoccoides. Regarding gut immunity, the supplementation of AH resulted in changes in intestinal immune cells, including reduced CD3+CD4+ T cells, which are a type of helper T cell, in the small intestine of birds (P=0.049). Additionally, there was a tendency to increase the expression of antioxidant function-related gene such as GPX2 (P=0.060), but no significant changes were observed in cytokines such as IL1b, IL6, and IL10. Overall, the addition of AH root powder may have positive effects on the microbiome of the chickens. This may help promote gut health in broiler chickens at the age of d 10 to 28.

  • Extent of reduction in protein digestibility by Godulbaegi(lxeris sonchifolia H.) kimchi powder appeared to be related to the kimchi weight-to-protein weight ratio, the kind of protein sources, part of plants and fementation period. In vitro digestibilities of protein were significantly(p<0.05) reduced as the freeze dried kimchi powder weight-to-protein ration increased from 0.5 : 1.0 to 1.0 : 1.0 for all Godulbaegi samples and protein sources. Overall digestibility of protein sources in the presence of kimchi powder, the reduction ranked in the following order : soybean>casein>beef>squid. Lower(p<0.005) reduction occurred for each protein source when raw plant was exchanged for kimchi products. Some greater reduction of digestibility was noted in young plants and leaf samples than ripe or root samples. Trypsin inhibitor, which expressed as soybena trypsin inhibitor, was inversely related(r=0.8437) to in vitro protein digestibility of casein in the presence of Godulbaegi kimchi powder. More than three times of total polyphenols contained in leaves than in roots. Young leaves had 30% more total polyphenols(37.64mg/g sample) than that in ripe ones. Soaking in 5% NaCl solution for 24 hrs was markedly reduced in total polyphenols as 73% for leaves and 33% for roots. Remarkable reduction in total polyphenols was not checked during fermentation followed after soaking. Trypsin inhibitor content correlated well(r=0.8873) with total polyphenols in all of Godulbaegi samples.

  • This study was conducted to investigate the quality characteristics and antioxidant activity of Kochujang following the addition of deodeok (Condonopsis lanceolata) powder. To accomplish this, 1%, 3% and 5% deodeok powder was added to Kochujang and the samples were then incubated at $30^{\circ}C$. during which time the general ingredients, water content, acidity, salinity, reducing sugar content, amino-nitrogen content and DPPH were analyzed at intervals of about two weeks. The water crude protein, crude fat and ash content were 3.61%, 8.44%, 4.62% and 8.85%, respectively. The initial acidity was 3.23~3.97%, and this increased to 4.39~44.86%. highlight please clarify this, I cannot infer your intended meaning; however, this can likely be deleted. The salinity was 7.42~7.73%, and 5% with deodeok powder producing the lowest content and showing a tendency to decrease during the storage period. The early amino-nitrogen content was 274.0~333.1%, with higher nitrogen contents being associated with large amounts of deodeok powder. The amino-nitrogen content during the storage period increased to the 4th week, then decreased. Additionally, the a value decreased sharply during the 4-week storage period. Addition of large amount of deodeok powder significantly improved the free radical scavenging activity. The free radical scavenging activity of 1%, 3% and 5% deodeok powder was higher than that of Kochujang throughout the maturation period. Overall, the results of this study indicate that there is the potential to develop functional foods by the addition of deodeok.

  • A batch experiment was conducted to evaluate the removal capacity of welsh onion(Allium fistulosum L.), shallot (Allium ascalonicum L.), garlic (Allium sativum L.) roots as an adsorbent for Ni and Pb in aqueous solution. One gram of the dried Allium root powder was reacted in 100ml of solution containing 10mg of each heavy metal and effects of metal concentration, pH, temperature, and size of adsorbent on the removal efficiency were evaluated. The results were as follows ; The amount of adsorption of heavy metal ions were higher with the smaller particles size of adsorbent. Garlic root was high adsorption capacity of Pb, especially. The higher concentration of heavy metal solution was, the more amount of adsorption of heavy metals was. The adsorption ratio was differed from a kind of heavy metal. As the temperature increased, the amount of adsorption of Ni and Pb by shallot and welsh onion were decreased. The amount of adsorption of Ni was high under alkali conditions but the amount of adsorption of Pb was high under neutral and acidity condition.
