This study evaluates the microbial safety of ginseng sprouts packaged in moss and a modified atmosphere (MA) film within Styrofoam boxes. Ginseng sprout samples were stored at 4℃ for seven days, and the total fungi and aerobic bacteria counts, relative humidity, and moisture content were measured at 0, 1, 3, 5, and 7 days. During the storage period, both packaging treatments caused an increase in the total fungi and aerobic bacteria counts. However, by the seventh day, the ginseng sprouts packaged in the MA film demonstrated significantly lower counts of total fungi (3.03 log CFU/g) and aerobic bacteria (7.32 log CFU/g) than those in moss (3.66 and 7.63 log CFU/g, respectively). Moss packaging alone resulted in the total fungi count reaching up to 3.36 log CFU/g, with the aerobic bacteria count consistently exceeding 7 log CFU/g, highlighting the importance of hygienic management. Moreover, no significant differences were observed in the moisture content and relative humidity between the MA-film- and moss-packaged groups throughout storage. These findings indicate that the functional MA film is a more hygienic packaging solution for ginseng sprouts than moss.

Ditylenchus destructor isolated from diseased ginseng roots was cultured on ginseng calli, fungal mycelium (Fusarium solani), carrot discs and radish sprouts. Effects of temperature, organic material and flooding on the nematode population changes were examined. D. destructor multiplied readily on the culture media except radish sprout medium, and was cultured best on the fungal culture at 2$0^{\circ}C$. Feeding of the fungal hypha and radish root hairs, molting and mating in the fungal culture medium were observed. Addition of organic materials (perilla, sesame, soybean and ginseng leaves) in soil significantly increased Aphelenchus avenae and saprophytic nematode populations, while D. destructor populations changed little and the nematode population growths were limited by the organic amendments (except sesame leaves). The nematode populations in soil including D. destructor were decreased by flooding. The results indicate that D. destructor may survive but not multiply readily in soil without host plants and that it can be effectively controlled by flooding.

Changes in weight, length, amino acids, organic acids and free sugars of soybean sprouts germinated with extract of Panax ginseng(PGE, 100∼400 ppm) were investigated. PGE increased the weight and length of soybean sprouts. Content of total amino acid in soybean sprout germinated at 100 ppm of PGE after cultivation for 3 days was the most abundant and then decreased by increasing the concentration of PGE. Content of aspartic acid was increased with culture time, but that of glutamic acid was shown to be an opposite trend. Content of total free sugar was increased by increasing culture time and not affected by concentration of PGE. Content of sucrose in control group during growth of soybean sprout was decreased, but sucrose contents in PGE groups were increased to 3 days and decreased thereafter. However, the other sugars were continuously increased for 4 days. Content of total organic acids was the most abundant in soybean sprouts germinated with 200 ppm of PGE and cultured for 3 days. Phytic acid was a major organic acid, showing the range of 45 to 60% for total organic acids. In conclusion, PGE as sprouting water of soybean was effective to increase of growth, contents of amino acids and organic acids in soybean sprouts, indicating that PGE accelerated the quality of soybean sprouts.

To determine the effects of mulching with the hulls of rice on the growth of the ginseng plant and changes of its growing environment-soil moisture content. subterranccan temperature and soil hardness- were investigated under different light intensity such as 5%, 10%, 20%, and 30% light transmittance rate(LTR). The results obtained were as follows; 1. Soil moisture content under the shading was decreased as the increase of light intensity, whereas it was increased about 1.5% in each plot of LTR by the mulching. 2. Suberranccan temperature under the shading was increased as the increase of light intensity. It was decreased on a hot day by the mulching but increased on a cold day. 3. Soil hardness was decreased by the mulching. 4. Sprouting date of the ginseng plants was acclerated for 7 days and sprout periods were shortened for f days by mulching compared to the non-mulching treatment. 5. Missing plant rate was increased severely as the increase of light intensity more Than 20% LTR In the non-mulching plots but did not severe in the mulching plots. Missing plant rate was decreased remarkably by the mulching. The degree of decrease was larger as the increase 6f light intensity. 6. Root yield was increased in the mulching plots compared to the non$.$mulching plots. The degree of increase was larger as the increase of light intensity. The highest yield was obtained at 20% LTR with mulching.

As the rural population continues to decline and aging, the improvement of agricultural productivity is becoming more important. Early prediction of crop quality can play an important role in improving agricultural productivity and profitability. Although many researches have been conducted recently to classify diseases and predict crop yield using CNN based deep learning and transfer learning technology, there are few studies which predict postharvest crop quality early in the planting stage. In this study, a early quality prediction model is proposed for sprout ginseng, which is drawing attention as a healthy functional foods. For this end, we took pictures of ginseng seedlings in the planting stage and cultivated them through hydroponic cultivation. After harvest, quality data were labeled by classifying the quality of ginseng sprout. With this data, we build early quality prediction models using several pre-trained CNN models through transfer learning technology. And we compare the prediction performance such as learning period and accuracy between each model. The results show more than 80% prediction accuracy in all proposed models, especially ResNet152V2 based model shows the highest accuracy. Through this study, it is expected that it will be able to contribute to production and profitability by automating the existing seedling screening works, which primarily rely on manpower.

This study has been designed to stress the thoughts that soups should be offered taking into account customer's preference aimed at leading to eventual customer's satisfaction and the importance that Korean traditional food should take the lead in shifting dining-out industry's paradigm to customer-orientation instead of product-orientation. From August 15 through August 30, 2003, the drawn-up questionnaires were handed out to 500 numbers of adults aged over 20 living in Seoul, metropolitan city of Korea and the finally collected 361 questionnaires from them have been analysed as a subject for this study. It showed that the male respondents(44%) dined out much more frequently than the female respondents(35%) and their rate of 5,000-7,000 Won for a meal was most preferred as their average expenditure at one sitting in the restaurant. When eating Korean food at home or in a restaurant, the majority(5l,3%) of them think the soups(Tang) should be served coupled with their ordered meals. Among soups using flesh and meat as a staple material, they most preferred beef & bone soup(33.2%), followed by beep rib soup(30.4%) and beef soup with seasoned red pepper(l0.8%), and among soups using fish & shell and crustacean as a staple material, most preferred were hot fish soup(20.6%), loach soup(l5.2%) and hot crab soup(11.4%). Among soups using beans as a staple material, they most preferred soybean paste stew(33.2%), uncurdled soybean curd stew(29.4%) and Dambuk stew(l5.8%). Among soups using fowls and birds as a staple material, chicken soup with ginseng(51.9%), plain chicken soup(l8.4%) and chicken soup with red pepper sauce(l2.3%) falls on the most preferred. Among soups using vegetables and seaweeds as a staple material, most preferred are sea mustard soup(25.3%), Kimchi soup(16.8%), soybean paste soup with Chinese cabbage(13.0%) and bean sprout soup(10.1%). The soups(Tang) most preferred in the morning time are those soups whose staple materials are vegetables and seaweeds, such as sea mustard soup, bean sprout soup, Kimchi soup and soybean paste soup with Chinese cabbage while the soups most preferred for the lunch time are beef & bone soup, beep rib soup, chicken soup with ginseng and beef soup with seasoned red pepper while beef soup with seasoned red pepper, beef & bone soup, soybean curd stew and Kimchi soup are most preferred soups for the dinner time. The survey showed that 41 % of the subject preferred chicken soup with ginseng for a food considered good by themselves for their health. The male respondents preferred Bosin-tang(soup of edible-dog meat) than the female counterparts did, while the female respondents preferred chicken soup with ginseng than the male counterparts did. The survey showed that when eating korean traditional food, 70% of the subject are visiting a restaurant where soups are cooked delicious while 61% of the subject think that price does not matter if only food tastes good, which is reflecting that taste of food is a decisive factor in selecting menu rather than its price is. In conclusion, you can say that taste of soup is the most important factor creating steady customer in the restaurant, taking it into account Korean people most prefer their traditional food when dining out.

Recently, the agricultural environment in Korea is rapidly changing due to the aging and decline of the agricultural population, and in order to solve these problems, it is urgently required to improve the agricultural productivity and reduce the labor force. To solve this problem, a smart farm fused with ICT technology is being proposed as an alternative. In Korea, smart farms are currently mainly used in greenhouses. In this paper, this smart farm technology is to be applied to the cultivation of sprouted ginseng. To this end, we use seedlings (about 1.0g) to grow a solid medium and bed for cultivating sprouted ginseng, a fresh ginseng that is produced in a short period of time (2~3 months) with a clean environment management technology that does not use chemical pesticides and hydroponics in a greenhouse developed. In addition, an IoT-based growth environment management system was developed to monitor the growth process of sprouted ginseng in such an environment and to control driving devices.

Background: Ginsenosides, which have various physiological activities, are known to be abundant in the leaves and roots of ginseng. Ginseng sprouts can be used as a fresh vegetable and roots, stems, and leaves of ginseng can be consumed. This study aimed to investigate the effect of carbon dioxide treatment and the modified atmosphere (MA) packaging method in suppressing quality deterioration during the distribution of ginseng sprouts. Methods and Results: Ginseng sprouts were packed using Styrofoam, barrier film + non gas treatment, barrier film + gas treatment, 15 ㎛ polyamide (PA) double film + non gas treatment, 15 ㎛ PA double film + gas treatment, 25 ㎛ PA film + non gas treatment, or 25 ㎛ PA film + gas treatment. Quality parameters including gas composition, relative humidity, chlorophyll SPAD (Soil Plant Analysis Development) value, firmness, and rate of quality loss in ginseng sprouts were monitored at the following temperatures: 20℃, and 10℃. Ginseng sprouts packaged with 25 ㎛ PA film showed loss in quality because of wilting owing to low relative humidity within the film. Chlorophyll and firmness did not differ between film and gas treatments. The time point at which the combined loss from softening and decay owing to fungal, and bacterial infection and wilt reached 20% was considered the limit of distribution. At 20℃, the packaging not included in the 20% distribution loss rate limit or up to 7 days was 15 ㎛ PA double film + gas treatment. At 10℃, the packaging not included in the 20% distribution loss rate limit for up to 18 days were barrier film + gas treatment and 15 ㎛ PA double film + gas treatment. Conclusions: The film packaging suitable for the distribution of ginseng sprouts was found to be the barrier film and PA film with low gas permeability and maintaining hygroscopicity at 95% relative humidity. To prevent the loss in quality of ginseng sprouts, gas treatment (8% of O₂ and 18% of CO₂) in the film was found to be more suitable than no gas treatment for inhibition of decay.
