  • Purpose: The objective of this study is to evaluate the effect of cultivation conditions on the growth and glucosinolate content of Chinese cabbage and kale. Methods: Chinese cabbage and kale were grown in three different cultivation conditions, including a plant factory, greenhouse, and open field. Samples were collected at two harvesting times (10 d and 20 d after transplanting the seedlings). Nine growth parameters (plant height, plant width, number of leaves, petiole diameter, SPAD readout, leaf length, leaf width, stem diameter, and plant weight) were measured immediately after harvesting, and the samples were freeze-dried and stored until the glucosinolate content was analyzed. Mean values of the growth parameters and glucosinolate contents were evaluated using Duncan's multiple range tests. Results: The results indicated that the plant parameters of the Chinese cabbage and kale were greater for plants grown in the plant factory and greenhouse. The plant height, width, and weight showed significant differences in the Duncan's multiple range tests at a 5% level. The plant factory also produced greater contents of most of the glucosinolates. Conclusions: Three different cultivation conditions significantly affected the growth and glucosinolate contents of Chinese cabbage and kale. Further study is necessary to investigate other functional components and different vegetable varieties.

  • This study compared and analyzed the consumption and amount of red pepper used in Baechu Kimchi (cabbage Kimchi) especially the amounts used in Kimchi recipes with respect to the passage of time from the 1930s to the 2010s. In this analysis, 78 recipes for cabbage Kimchi were taken from books, daily newspapers and magazines from 1930 to 2014 and collected for comparison. The result of the study showed that the consumption and inclusion of dried red pepper powder in cabbage Kimchi increased. The average consumption of red pepper in the 1930s was 5.75 g, and the number went up to 8.83 g in the 1940s, to 13.8 g in the 1950s, and to 20.25 g in the 1960s. The amount dramatically increased from 1970 to 1980 (53.37 g) and kept rising until 2010 (71.26 g). The average consumption of red pepper in cabbage Kimchi in the 2010s is about 12 times that of the 1930s.

  • Dried cabbage, spinach, carrot, mugwort and yam were irradiated at 1, 5 and 10 kGy using a $^{60}Co$ irradiator at room temperature. Effects of irradiation dose and storage time on irradiated dried vegetables were investigated through electron spin resonance (ESR) spectroscopy. Strong positive correlation coefficients ($R^{2}=0.9698-0.9915$) were obtained between irradiation dose and corresponding ESR signal intensity. ESR signal of mugwort was most stable at 9 weeks storage, followed by carrot, yam, and spinach, whereas that ESR signal of cabbage was not distinguishable.

  • A pot experiment was conducted to study the effect of urea and ammonium nitrate on the use of soil born potassium and the yield of chinese cabbage (Brassica pekinensis, Var. Heungnong, Seoul). Results obtained are shown as follows; 1. In comparison with urea, ammonium nitrate lowered soil pH and promoted the utility of soil born potash by chinese cabbage which resulted in the increase of the yield at no potash applied cultivation. 2. Ammonium nitrate seemed to be more effective than urea on the growth of the edible part of chinese cabbage (inner leaves of cabbage) and the effect was much promoted by the addition of potash. 3. The greater the yield of edible part of cabbage, the lower the N/K ratio of dry mater. The highest yield was obtained at N/K ratio of 1.4 in 1.2-1.3 m.e/g K range of the dried cabbage.

  • BACKGROUND/OBJECTIVES: We investigated total 26 ingredients of Saengshik which will be commercially produced as an anti-diabetic dietary supplement. SUBJECTS/METHODS: Thirteen vegetables, nine cereals, three legumes and one seed were extracted with aqueous ethanol for 2 h at $60^{\circ}C$, and evaluated for their inhibitory effects against ${\alpha}$-amylase and ${\alpha}$-glucosidase and for total phenolic and flavonoid contents. RESULTS: All ingredients inhibited ${\alpha}$-amylase activity except cabbage. Strong inhibitory activity of ${\alpha}$-amylase was observed in leek, black rice, angelica and barley compared with acarbose as a positive control. Stronger inhibition of ${\alpha}$-glucosidase activity was found in small water dropwort, radish leaves, sorghum and cabbage than acarbose. All Saengshik ingredients suppressed ${\alpha}$-glucosidase activity in the range of 0.3-60.5%. Most ingredients contained total phenols which were in the range of 1.2-229.4 mg gallic acid equivalent/g dried extract. But, total phenolic contents were not observed in carrot, pumpkin and radish. All ingredients contained flavonoid in the range of 11.6-380.7 mg catechin equivalent/g dried extract. CONCLUSIONS: Our results demonstrate that Saengshik containing these ingredients would be an effective dietary supplement for diabetes.

  • Effects of freeze-drying time on the microbiological, sensory, and other characteristics of freeze-dried kimchi were investigated to optimize freeze-drying time for kimchi. Quality attributes of freeze-dried kimchi, including number of lactic acid bacteria (LAB), pH, sensory properties, brittleness, rehydration property, moisture content, and microstructure of Chinese cabbage were observed for 24, 48 and 72 h, respectively. Number of LAB and pH of the kimchi freeze-dried for 24 h were significantly changed in comparison with those of the kimchi not freeze-dried. However, further freeze-drying did not change markedly number of LAB and pH. Overall acceptability of the sample freeze-dried for 48 of 72 h was better than that of the sample freeze-dried for 24 h. As freeze-drying time increased, brittleness of the dried sample increased, and rehydration property was improved while dried weight and moisture content of the sample decreased. In conclusion, the sample freeze-dried for 48 h was better than the sample freeze-dried for 24 or 72 h, based on sensory properties and other characteristics.

  • In order to study on the riboflavin content of common foods for Korean and the rates of destruction of riboflavin during cooking 26 kinds of the foods were selected and 3 kinds of menu were cooked by standardized method. For each food item and menu riboflavin content was measured by AOAC method. The experimental values of 13 kinds of food such as rice oak mushroom carrot squarsh tangle dried large anchovy apple(Fuji) dried laver ramyun pork soybean curd fried soybean curd and danmugi were almost consistent with food compo-sition values. Whereas those of 12 kinds of foods such as cabbage onion potato kimchi beef sausage dried medium anchovy hair tail soybean paste and egg were considerably different from food composition table values, up to now Alaskan pollack maize loaf bread hamburger bread etc have not been analyzed in food composition table, The rates of retention of riboflavin in menu 1, 2, and 3 cooked by standardized method were 24% 69% 46% respectively. The overally retention rate was in inverse proportion to the time of sunlight exposure during cooking.

  • 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.

  • In order to investigate the stimulatory effect(hormesis) of low dose gamma-radiation on the seeding growth of old seeds with respect to antioxidant defense systems, various doses of gamma radiation to the 5-year-old dried seeds of Chinese cabbage (Brassica campestris L. cv Sulin eockaei). Compared to the new, 1-year- old seeds, old seeds irradiated by low does gamma radiation in the range of 1-2 Gy showed vigor growth as revealed by statistically significant increases both in the germination rates and the leaf size and fresh weight. Further, seedlings grown from seeds treated by low dose gamma radiation showed higher peroxidase and catalase activities than non-treated seedlings. These results suggest that the antioxidant defense systems could be closely related to the stimulatory effects of low dose radiation.

  • Indolo[3,2-b]carbazole(ICZ) is a potent Ah receptor agonist with biological activities similar in several respects to those of the potent environmental toxin, TCDD. ICZ is produced during the oilgomerization of indole-3-carbinol(I3C), a breakdown product of the glucobrassicin present in food plants of the Brassica genus. In the present study we examined ICZ levels in tissues and excreta of rats treated with I3C or dietary cabbage of established glucobrasicin content, and in feces of conventional and germfree rats fed on a basal diet, and of humans. We also examined the levels of cytochrome P4501A1 induction, as determined by the ethoxyresorufin ο-deethylase assay, in tissues of animals that received cabbage-supplemented diets, or which were treated with purified I3C or ICZ. Our findings indicated that incorporation of either homogenized or whole freeze-dried cabbage in the feed led to large increases(16-60 fold) in the levels of ICZ in the feces and lower gastrointestinal tract of rats. We observed that whereas ICZ is readily detectable at about the same levels(2.00$\pm$0.50 ppb) in the feces of conventional rats fed on a purified diet and in human feces, levels of ICZ in the feces of germfree animals fed on the basal diet were at the limits of detection(0.40$\pm$0.20 ppb), indication that gut bacteria are important for the production of ICZ from essential dietary constituents in the basal diet. We showed that in contrast to the near 7000-fold difference in CYP1A1 inducing potencies of ICZ and TCDD in cells in culture, their inducing potencies differ by only about an order of magnitude in rats. Nonetheless, the levels of ICZ remaining in livers twenty hours after I3C treatment appear too low to account for the induced activity. This result indicates that ICZ may be rapidly cleared from the liver or that substances other than, or in addition to, ICZ be responsible for the enzyme-inducing activity of orally administered I3C or its precursors.
