  • A comparison was made of the effect of different packaging materials on storability of mixed sprout vegetables (alfalfa, broccoli, cabbage, radish, and red radish) stored at $8^{\circ}C$. They were packaged by several kinds of films that were 50 fm thickness low-density polyethylene film (PE 50), 50 fm thickness polypropylene film (PP 50), $50{\mu}m$ thickness ceramic film (CE 50), $25{\mu}m$ thickness ceramic film (CE 25), $10\sim13{\mu}m$ thickness polyethylene film (wrap), and polyethylene terephthalate box with ventilation hole (box). The fresh weight of mixed sprouts packaged with different materials decreased below to 2% except box packages that decreased around 7% compared with initial weight. The atmospheres that were developed inside the different materials during storage differed significantly. The carbon dioxide and oxygen concentration of packages were kept properly with 5% in CE 25, but the PE 50 and CE 50 treatments showed higher carbon dioxide and lower oxygen concentration. So the off-flavor of mixed sprouts was more severe in the PE 50 and CE 50 treatment. The ethylene concentration of packages showed lowest in box treatment, followed by PP 50, wrap and CE 25 treatment. The overall quality of mixed sprouts was lower in PE 50 and CE 50 than CE 25 treatment after 10 days storage, supposed to be resulted from highest ethylene concentration and lowest oxygen concentration. Conclusionally, the CE 25 film that showed below 1% fresh weight loss, 5% carbon dioxide, 5% oxygen and below 4 ppm ethylene concentration in package may be a proper packaging material for mixed sprout vegetables.

  • Six kinds of sprout vegetables were applied three and six types of non-perforated breathable propylene films (NPB film) for individual and mixed modified atmosphere (MA) package condition at $10^{\circ}C$ on this study. As a tah tasai, kohlrabi, rape, chinese cabbage, red radish, broccoli sprouts were packaged by 20,000, 60,000, and 100,000 $cc{\cdot}m^{-2}{\cdot}day{\cdot}atm$ non-perforated breathable films for seven days storage. Mixed sprout vegetables were used 20,000 cc, 40,000 cc, 60,000 cc, 80,000 cc, and 100,000 $cc{\cdot}m^{-2}{\cdot}day{\cdot}atm$ non-perforated breathable films for seven days storage. Loss rate of fresh weight, changes of carbon dioxide, oxygen, and ethylene gas concentration were measured during the storage. Visual quality and off-flavor were rated by panel tests after seven days storage. Each sprout vegetable storage with film tests had been shown under the 0.5% fresh weight loss in every packaged films, and the 20,000cc NPB film package had been suitable atmosphere condition in the carbon dioxide and oxygen gas concentration. Appearance and off-odor of sprouts packaged with 20,000cc NPB film were shown better than other films because of the proper gas movement through the film to outside during the storage. Fresh weight loss of the mixed sprout vegetables had no difference among the NPB films for seven days storage. The 20,000 cc film had been resulted in that exchange rate of carbon dioxide and oxygen was highest cause of low film permeability than sprouts respiration. But the film is not good for storage because it has been made poor value of off-order even showed high visual quality from panel test after storage. 40,000 cc and 60,000 cc non-perforated breathable films were more suitable for mixed sprout vegetable storage at $10^{\circ}C$. These result suggested that 20,000 cc NPB film was good for single packaged sprout vegetable and 40,000 cc and 60,000 cc non-perforated breathable films were good for mixed packaged sprout vegetable.

  • With the enlargement of school meals, the lunch program has played an important role in educating young students about good eating habits and food Preferences. The objective of this study was to investigate the awareness and preference of vegetables and to provide preliminary data required for framing a menu of school meals to help students maintain good food preference and eating habits with a balanced food diet. A survey was conducted from 25th October to 27th November, 2004 with 873 elementary school students (M: 474, F:399) in the 4th, 5th, or 6th grade of 6 schools in Daegu and Gyeong sang but do (Yongchon, Gumi, Pohang). Satisfaction for the school meal was rated by $52\%$ of the students and 'rice and soup' was the favorite meal type. Eating habits of students were not influenced by the employment status of their mothers. Only $11.2\%$ of students selected vegetable as their favorite food. Marsh mallow, taro stem, green bean sprouts, crown daisy and broccoli showed very low awareness and were selected as the least favorite vegetables. The most important criteria of preference were the taste and eating experience of the vegetables. The most preferred cooking method of the vegetables was tchigae which is a simple stew. Recognition of frequency for daily eating vegetables significantly affected the real intake of vegetables for everyday meals and the preference of vegetables also significantly affected the vegetable intake from the school meals. Compared to the school dietitian, mothers showed a greater frequency in being selecting as an educator of nutritional information. The above results indicated the need to improve the level of students' understanding of the importance of vegetables in the daily diet with parental education and publicity.

  • Sprout vegetable and general vegetable were obtained from radish, red cabbage, vegetable green, buckwheat and broccoli seeds. The vitamin contents had a large deviation, and the vitamin B1 contents decreased and/or was not detected according to the sprouting. This tendency occurred because of the use for growth of sprouts. The mineral contents in sprout vegetables was the highest and was 2~10 times greater than general vegetables. In the growing pathway, potassium was a large consumption nutrient and consumption of sodium was low. $\alpha$-Amylase and total enzyme activities were higher in sprout vegetable than general vegetable, which was also the case of the corresponding freeze dried powders. Sprouting was shown to increase the enzyme activities. Thus, sprout vegetables had several advantages including a rich level of nutrients and safety from agricultural pesticides.

  • The purpose of this survey was to investigate the food behavior and vegetable preferences of elementary school students in the metropolitan areas of, South Korea. Five hundred and eighty students (277 male and 303 female) studying in grades 5~6 participated in the survey. We assessed food behavior by evauating the Nutrition Quotient (NQ). Through a questionnaire, which consisted of 20 food behavior checklist items. These items were grouped under five factors: balance, diversity, moderation, practice and environment. All data were analyzed using SPSS 25.0. The average NQ score weighted using the five factors was 61.32 points. Among the five factors, moderation showed the lowest score, whereas environment showed the highest score. The average score of the vegetable preference was 3.36 points out of a total of 5 points. The vegetable preference was found to be highest for bean sprouts and followed by tomatoes, lettuce, spinach, Chinese cabbage, sesame leaf, pumpkin, carrot, radish, chives, lotus roots, onions, broccoli, sweet peppers, and eggplant. The results of vegetable preferences by NQ grade were 4.13±0.63 points for the high grade, 3.68±0.75 points for the medium-high grade, 3.41±0.82 points for the medium-low grade, and 2.94±0.78 points for the low grade. There was a significant positive correlation between NQ and vegetable preferences (r=0.477, P<0.001). If vegetables with high preference are frequently provided in school meals, it might contribute to improving overall food behavior.

  • The purpose of this study was to develop an excellent salad dressing using grape seed oil, which contains high levels of unsaturated fatty acids. First, a vinaigrette was made with grape seed oil and vinegar and divided into five portions. Then, five types of mirepoix au maigre ($M_1,M_2,M_3,M_4,M_5$) were made with apple, onion, carrot, garlic, tomato puree, and tomato ketchup by mixing in a main material vessel. The samples were then allowed to ripen for three days. The control group $M_1$ was named $GD_1$, and the experimental groups $M_2,\;M_3,\;M_4,\;and\;M_5$ were named $GD_2,\;GD_3,\;GD_4,\;and\;GD_5$. respectively. To measure receptiveness, a sensory test was conducted using a 7 point category scale. The test concentrated on flavor, taste, color, agreeability, aftertaste, and overall acceptability: the panel consisted of 15 subjects According to the results, $GD_4$ had the best flavor, color and agreeability. The samples with the most preferred taste and aftertaste were $GD_4\;and\;GD_5$. Between $GD_4\;and\;GD_5$, there were no noticeable differences in taste, aftertaste, or overall acceptability, but differences in color and agreeability did exist. Thus, $GD_4$ proved to be the most favorable product. To determine the best complementing vegetables for $GD_4$ yam($VE_1$), broccoli sprouts($VE_2$), mustard leaves($VE_3$), beet leaves($VE_4$), cucumber($VE_5$), and lettuce(VE6) were selected as samples, and a sensory test was conducted. Each vegetable has its own peculiarities. According to the results, $VE_2$ had the nicest vegetable fragrance recording the highest mean value. The vegetable with the most preferred taste, aftertaste, and agreeability were $VE_2\;and\;VE_6$. $VE_1\;and\;VE_6$ had the nicest color and contained the brightest color as well. The highest overall acceptability was awarded to $VE_2\;and\;VE_6$ and there was no remarkable difference between thorn at a level of 0.05. In conclusion, $VE_2\;and\;VE_6$ were the best complementing vegetables with grape seed oil dressing. However, to commercialize such a dressing, many follow-up studies must be conducted.

  • Purpose: The aim of study was to determine the effects of carbohydrate, fat, protein, and fiber contents on glycemic responses in a single food item or meal. Methods: Glycemic responses were measured in 30 healthy young adults (17 males and 13 females) with various test foods, including rice, egg whites, bean sprouts, olive oil, noodles, prune, broccoli, Korean dishes, Western dishes, and salad dishes, etc. Test foods were designed to contain various carbohydrate, fat, protein, and fiber contents in single or mixed foods or dishes. After 12 hours of fasting, participants consumed test foods, and the glycemic response was measured for a subsequent 120 min (0, 15, 30, 60, 90, and 120 min). Three hundred and fifty three glycemic responses from 62 foods were collected. The incremental area under the curve (AUC) was calculated for each test food for each subject to examine glycemic responses. Statistical analysis was conducted to identify which macronutrient (carbohydrate, fat, protein and fiber) affected the AUC using a mixed model. Results: Carbohydrates (${\beta}=37.18$, p < 0.0001) significantly increased while fat (${\beta}=-32.70$, p = 0.0054) and fiber (${\beta}=-32.01$, p = 0.0486) significantly reduced the glycemic response. Conclusion: It can be concluded that the glycemic response of a meal can be modified depending on the fat and fiber contents of ingredient foods, even though carbohydrate content is maintained.

  • Sprout vegetables containing various types of polyphenols and flavonoids, are known to have anti-inflammatory, antioxidant, cholesterol-lowering, and anti-obesity activities. However, there have been few reports on the anti-diabetic efficacy of sprout vegetables. Here, we investigated the anti-diabetic effects of sprout extract obtained from buckwheat, beet, rape, broccoli, kohlrabi, red young radish, and dachai, in high fat diet (HFD) and streptozotocin (STZ)-induced type II diabetes mellitus mice. The mice were fed a HFD (60% calories as fat) for 8 weeks prior to intraperitoneal injection with STZ (75 mg/kg). The diabetic mice were divided into four groups: standard diet (STD, 10% calories fat), HFD, HFD with sprout extract (SPE) and HFD with metformin (MET). After 4 weeks, body weight gain was much lower in both SPE and MET groups than in HFD group. In contrast, there was no difference experiment groups regarding food intake ratio. The level of fasting blood glucose was significantly lower in the SPE and MET groups compared to the HFD group. Oral glucose tolerance and insulin tolerance in the SPE and MET groups were significantly ameliorated in comparison to the HFD group. The concentrations of serum total cholesterol, triglycerides, and LDL cholesterol in the SPE and MET groups were remarkably reduced in comparison to the HFD group, and HDL cholesterol concentration was higher in the SPE and MET groups than in the HFD group. Glutamate oxaloacetate transaminase and glutamate pyruvate transaminase levels were between SPE and HFD groups. The serum insulin and leptin concentrations were significantly reduced in both the SPE and MET groups compared to the HFD group. Therefore, these results indicate that sprout extract could improve insulin resistance and attenuate blood glucose level in HFD/STZ-induced type II diabetes mellitus mice. We conclude that this study may provide positive insights into sprout extract as a functional food ingredient for treatment of type II diabetes mellitus.

  • This study was performed to investigate the effects of vegetable sprout powder on serum and adipose tissue lipid metabolism in rats fed high-fat diet for 4 weeks for induction hyperlipidemic model rat. Weight-matched male Sprague-Dawley rats were assigned to five groups according to dietary fat level (10% or 20% of diet wt.) and mixture of vegetable sprout powder levels (5% or 10% 10% or 20% of diet wt.). Vegetable sprout powder was the mixture of same amounts of dried barley, broccoli, rapeseed, alfalfa, radish, mustard, buckwheat and brussels sprouts. Experimental groups were normal fat diet with 5% cellulose (NF-C), high fat diet without fiber (HF-N), high fat diet with 5% cellulose (HF-C), HF-C diet with 5% vegetable sprout powder (HF-CSL), and HF-C diet with 10% vegetable sprout powder (HF-CSH). The body weight of HF-N group increased 16% compared with the NF-C group, while it was decreased by 15% and 22% for HF-CSL group and HF-CSH group, respectively. Fat mass and fat cell size of adipose tissue were lower in HF-CSL group and HF-CSH group compared with HF-C group, and lower in HF-CSH group compared with HF-CSL group. Serum triglyceride, total cholesterol and LDL-cholesterol contents were markedly decreased by vegetable sprout powder containing diet, while the serum HDL-cholesterol and phospholipid contents were higher in vegetable sprout powder containing diet in a dose-dependent manner. Leptin and insulin levels in serum showed a decrease in HF-CSH group. Significantly increased contents of triglyceride, total cholesterol, LDL-cholesterol, leptin and insulin in the serum of HF-N group were returned to normal or even below normal levels by feeding 10% vegetable sprout powder diet. The increased activities of NADP-malate dehydrogenase (ME), glucose-6-phosphate dehydrogenase (G6PDH) and 6-phosphogluconate dehydrogenase (6PGDH) and lipoprotein lipase (LPL) in adiposetissue by HF-N group were decreased to the activity of normal fat group by feeding vegetable sprout powder in a dose-dependant manner. These results indicate that lipid metabolism in rats fed high-fat diet was suppressed by feeding vegetable sprout powder.
