The purpose of this study was to optimum formulation conditions for the preparation of retort pouched marsh snail Senisulcospira livertina soup with curled mallow Malva verticillata and optimized the sterilization process. Samples were prepared according to the central composite rotatable design (CCRD) by encrypting the amounts of marsh snail broth, boiled marsh snail and blanched curled mallow, which are the main ingredients of retort pouched marsh snail soup with curled mallow. Raw marsh snail was sorted by size of 4-5 level, and then marsh snail was washed and removed sediment in a water tank for 3 min, then boiled at 100℃ for 10 min, and then directly separated by hand to prepared a boiled marsh snail. The marsh snail cube is prepared by combining blanched at 100℃ for 10 sec curled mallow (27 g) and green onion (20 g) with boiled marsh snail (27 g) and soybean paste (10 g). The marsh snail cube was placed with marsh snail broth (416 g) in a retort pouch film. Subsequently, sterilization (118.0℃, 25 min; F₀ value, 12 min) and cooling were performed using a steam retort.

In September 2017, vein clearing and yellowing symptoms resembling those caused by viruses were observed on leaves of Malva verticillata in Chungnam, Korea. Nucleic acids were extracted from leaves of five symptomatic plants and tested by reverse transcription polymerase chain reaction using four virus specific primer pairs including malva vein clearing virus (MVCV). Amplicons of the expected size (600 bp) were obtained from total RNA of all samples using the MVCV-specific primers. To confirm the presence of MVCV in symptomatic plants, the DNA fragments from three samples were purified, and directly sequenced. BLAST analysis revealed that it shared the highest nucleotide identity (99%) with a MVCV isolate from tomato (Mexico). The virus isolates obtained from the third re-inoculated Chenopodium was designated as Cm1-5. Tissue from Cm1, Cm3, and Cm5 isolates was mechanically sap inoculated into 23 indicator plants. Cm3 isolate induced chlorotic local and mosaic symptoms in Althaea rosea. Phylogenetic analysis based on coat protein gene of 19 MVCV isolates from 6 different countries and plant species, did not correlated with either the geographical origin of the isolates, or pathogenicity. To our knowledge, this study first reports the natural occurrence of MVCV on M. verticillata in Korea and characterization of three Korean isolates of MVCV.

This study examine the relationship between the intake of food conformable to each Sasang constitution and the recognition of irregular symptoms of health condition. The study subjects were 362 university students nationwide, classified by heir Sasang constitution. In terms of the intakes of conformable food and the symptom recognition, the number of multiple subjective symptoms tended to rise as the Soeum type digested the conformable food. As for the kinds of food, the Soyang type showed a significant positive correlation between the intake of cucumber namul and the symptoms of eyes and skin, but a negative correlation between the intake of Chongak Kimchi and the symptoms of the digestive system The Soeum type showed a significant positive correlation between multiple subjective symptoms and the intake of Gatkimchi, fernbrake namul, naeng-i soup, naeng-i namul, Korean leek Kimchi, crown daisy namul, and curled mallow soup, a significant positive correlation between the symptom recognition of the respiratory system and the intake of fried flatfish, and chicken gomtang but a negative correlation between the symptom recognition of the eye and skin and the intake of boiled eel. The Taeum type presented the a sigmificant positive correlation between multiple subjective symptoms and the intake of spaghetti, a positive correlation between the symptoms of the respiratory system and the intake of tuna salad, a positive correlation between the symptoms of the eye and skin and the intake of mafa tofu, spaghetti, and tuna salad, a negative correlation between the symptoms of the mouth and anus and the intake of codfish jiri, and a negative correlation between the symptoms of the respiratory system and the intake of tuna salad.

This study aimed to determine the changes in the vitamin B₅ content of raw and cooked vegetables. The nineteen vegetables were subjected to different cooking methods, viz. blanching, boiling, pan-broiling, and steaming. Vitamin B₅ was quantified by reversed-phase high-performance liquid chromatography (HPLC) using photodiode-array (PDA) detection (200 nm). The standard reference materials (SRM) were used to validate the accuracy of vitamin B₅ measurement method used in this study. The cooking yields ranged from 82.63 to 107.62% and decreased in most of the vegetables except bitter melon, curled mallow, and eggplant. The raw kabocha squash, Danhobak, had the highest vitamin B₅ content (0.671 mg/100 g) among the samples. All cooked vegetables showed lower vitamin B₅ content compared to the raw samples. The true retention ranged from 0% (crown daisy, blanching) to 84.49% (kabocha squash, steaming). These results indicate that vitamin B₅ is degraded after cooking. Pan-broiling and steaming are better cooking methods than the others for retaining vitamin B₅. The true retention of vitamin B₅ in the samples markedly depends on the cooking method and food matrix. These results can be used as important basic data for nutritional evaluation of meals.

Current study aimed to evaluate elementary school children's perception and eating attitude towards vegetables and analyze environmental factors influencing it. Survey was conducted among elementary school students and their parents in Gangwon district, 410 subjects each(Total 742, 391 students, 351 parents). The results are as follows. Both the children(64.3%) and the parents(84.9%) showed high concern over health. 46.6% of children and 52.4% of parents admitted unbalanced eating behavior, and commonly avoided foods were mostly vegetables such as mushroom, carrot, garlic, sweet pepper-green, welsh onion, kimchi, pumpkin, or beans. Unbalanced eating habit was significantly related to health consideration in choosing what to eat(p<0.01) and interest in health(p<0.05). 70.9% of children with unbalanced eating habit showed intention for correction, and those with high interest in health had stronger intention (p<0.01). Regarding children's perception of 20 kinds of vegetables frequently used in school lunch, swiss chard leaf beet, amaranthus magistratus, and curled mallow were rarely heard of or hardly eaten before. Korean chinese cabbage, radish(62.7%), cucumber(62.1%), perilla leaves(60.4%), lettuce(58.1%), and spinach(54.5%) were among the most frequently eaten. Survey result on children's preference for the vegetables shows lettuce, cucumber, Korean chinese cabbage, perilla leaves, spinach, and radish were highly preferred and stem of garlic, crown daisy, sweet pepper-green, pepper, and curled mallow were the least preferred. There was a significant positive correlation(p<0.01, p<0.001) between children's and their parent's preference for each vegetables, implying that children's preference towards vegetables is greatly influenced by their parent's choice. Children showed negative attitude towards vegetables with strong flavor and tended to avoid vegetables that they remember as not tasty. This suggest that strong flavor and negative prior experience is what determines children's attitude in vegetable consumption. Many children said they try to eat vegetables even if they haven't had it before, and this tendency was significantly correlated with the degree of interest in health(p<0.05) and the degree of consideration of health in choosing what to eat(p<0.001).
