The purpose of this study was to investigate Tteokbokki tteok that has properties of five different rice cultivars (Haiami, Samkwang, Goami, Saegyejinmi and, Seolgaeng). The moisture and crude protein contents of rice were 14.13-17.78% and 4.43-7.68%, respectively. The crude lipid and crude ash of rice were 0.45-1.84% and 0.37-0.85%, respectively. The water binding capacity of Goami cultivar was higher than that of other rice flours. Asa the soaking time increased, water absorption was the highest in the Goami cultivar (45.30%). Using a rapid visco analyzer (RVA), the initial pasting temperature of Goami cultivar was the highest; further, the peak viscosities of Samkwang cultivar and Saegyejinmi cultivar were higher than of those of other rice flours. The hardness of the Tteokbokki tteok was the highest the in the Goami cultivar (7,293.08 g); conversely, the Saegyejinmi cultivar had the lowest value (2,502.08 g). In the sensory evaluation of Tteokbokki tteok, the color, texture, and overall acceptability were the highest in the Saegyejinmi cultivar, the appearance was highest in the Samkwang cultivar, and the flavor was the highest in the Seolgaeng cultivar. Lastly, the Goami cultivar yielded the lowest values in the sensory evaluation, except for appearance and color.
This study produced hot-air-dried perilla leaf to add Korea's popular perilla leaf to fresh noodles to examine their value as food and get the best fresh noodle recipe by adding 0%, 3%. 6%, 9%, and 12% of perilla leaf to flour. The moisture content of the dough was highest at 34.41% for the control group with 0% perilla leaf, whereas the pH was lowest at 5.59 for the dough with 12% perilla leaf. As a result of WRC analysis of the dough, moisture absorption increased with greater perilla leaf content. The moisture content of fresh noodles was lowest for the control group with 0% perilla leaf, whereas the pH was highest for the control group. The L, a, and b values of the dough were highest for the group with 0% perilla leaf powder. Hardness and cohesiveness were lowest for the 0% group and springiness tended to decrease with increased amounts of hot air-dried perilla leaf. The number of microorganisms decreased significantly with greater perilla leaf content on the third and fourth days. As a result of the sensory test, the 6% dough showed the highest scores for all items including appearance, flavor, color, taste, and texture. Overall acceptability was also highest at 7.20 for the 6% dough and lowest at 3.27 for the 12% dough. Based on the above results, when producing fresh noodles by adding hot-air-dried perilla leaf powder, inhibition of microorganisms improved with greater perilla leaf content for longer storage, but the sensory properties were best when 6% perilla leaf content was added.

Background and Purpose : By preventing diseases caused by exogenous evil, disorder of internal organs, and seven modes of emotions and adapting to mother nature when the mind is unsettled, and keeping the body and mind relaxed diseases can be avoided, but there can be unpredicted situations caused accidentally by stroke. Currently the general prescription is regulating the flow of vital energy including drugs eliminating blood stasis. Even though the stroke is resulted from diseases caused by exogenous evil, by observing the patient's physical appearance, essence of life, vital energy, and mental faculties which are believed to be the functions of the heart to clear the upper body and invigorate the functions of the spleen and stomach and purge with drugs of warm nature is a closer approach than simply prescribing vital energy regulating drugs with eliminating blood stasis to the main purpose of treatment. Methods : 1) The subject of the study are 2 cases of patients who have visited the private hospital of the person who is announcing the results of the study. These patients have been given a diagnosis of edema or cystoma caused by bursitis in the knee joint through perception or medical examination and were waiting for operational application. 2) Sources related to stroke from Dong Eui Bo Gwam(東醫寶鑑) were used as the general standard of Korean Traditional Medicine, and to promote the understanding the original text and the translation has been given. 3) By observing the whole body such as the patient's usual physical appearance, essence of life, vital energy, and mental faculties which are believed to be the functions of the heart, or partly using the "Yin is even and well while Yang is firm" theory of "Plain Questions" as the background to present the results of the clinical study. Results and Conclusion : Generally the prescriptions from the first volume of Dong Eui Bo Gwam(東醫寶鑑) are mostly drugs eliminating stagnated blood including extravasated blood and the blood moving sluggishly in circulation or congested in a viscus, alleviating pain, invigorating blood circulation. Also prescriptions for bone fracture or fracture of bones and sinews are mostly to eradicate blood stasis with drastic drugs or coaptation drugs added to drugs eliminating stagnated blood including extravasated blood and the blood moving sluggishly in circulation or congested in a viscus, alleviating pain, invigorating vital energy, possessing warm properties for the Xue system.

Background: Unani System of Medicine (USM) has its origin to Greece. To ensure and develop the quality, authenticity of Unani drugs, standardization on modern analytical parameter is essential requirement for drugs. Objectives: The aimed of the present study was to develop a standard profile of "Qurṣ-e-Mafasil" by systematic study through authenticated ingredients, pharmacognostic identification followed by physicochemical, TLC, HPTLC fingerprinting analysis as per standard protocol. Material and Methods: In this study three batches of "Qurṣ-e-Mafasil" QM were prepared by standard method as per UPI had been followed by organoleptic properties of formulation such as appearance, color, odor, taste. Powder Microscopy and physicochemical studies were carried out such as Uniformity of weight, Friability, Disintegration time, hardness, LOD, ash vales and extractive values in like aqueous, alcohol & hexane. Further qualitative tests such as Thin-Layer Chromatography (TLC), and High-Performance Thin Layer Chromatography (HPTLC) studies were also carried out to develop fingerprint pattern of the alcoholic solvent extract of QM. Phytochemical screening was carried out in different solvent extracts such as alcoholic, aqueous and chloroform extracts to detect the presence phytoconstituents in the formulation QM. Heavy metals, Microbial Load Contamination and pesticidal residues were also determined. Results: Qurṣ-e-Mafasil showed tablet-like appearance, light brown colour, mild pungent odour and acrid taste. Uniformity of weight (mg), friability (rpm), and hardness (kg/cm) and disintegration time was ranged between (500 to 503), (0.0340 to 0.038), (8.40 to 8.67) and (4-5 minutes) respectively for the three batches. Loss in weight on drying at 105℃ was ranged between (8.3425 to 8.7346). Extracted values were calculated in distilled water ranged between (30.9091 to 31.4358), hexane (1.1419 to 1.4281), and alcohol (3.3352 to 3.3962).

The objective of this paper was to examine the oxygen requriement of rice seeds when the seeds were germinating under the water. The trial was carried out in the laboratory with the different water temperature (25$^{\circ}C$, 17$^{\circ}C$) in the Crop Experiment Station, Suwon. The tested varieties were 6 in japonica and 6 in indica (I) ${\times}$ japonica (J). In the 25$^{\circ}C$ water temperature rice seeds absorbed more dissolved oxygen (DO) and germinating duration was shorter than in the 17$^{\circ}C$ water temperature. DO uptake of japonica rice seeds was faster than that of indica ${\times}$ japonica rice seeds, and the germinating ratio of japonica rice seeds was higher than that of I${\times}$J rice seeds in the water. DO requirements of germinating rice seeds in the water were average 82.4 ${\mu}$g per seed up to coleoptile appearance and average 123.6 ${\mu}$g per seed up to appearance of radicle in the japonica varieties, but I${\times}$J varieties were 96.9 ${\mu}$g and 145.1 ${\mu}$g respectively. Especially when the rice seeds were germinated in the water, length of coleoptile and radicle of japonica rice were significantly longer than those of I${\times}$J rice varieties.
The aim of this study was to examine the effect of packaging on the quality maintenance of paprika (Capsicum annuum L. cv. Sirocco) stored at three different temperatures. Paprika was either unpacked (control) or packed with individual PP (propylene) film and stored at 10℃ and 20℃ for 30 days. Quality characteristics such as weight loss and appearance were examined. Paprika packed with PP film at 10℃ showed fewer quality changes compared to unpacked paprika stored at the other temperatures. Commercial properties tended to decrease rapidly during storage at 20℃ with unpacked paprika. The degree of fresh weight loss was significantly lower in packed paprika at 10℃ compared to unpacked paprika stored at other temperatures. It was found that general appearance, soluble solids content, and hardness were complexly affected by storage temperature and PP film packaging. A storage temperature of 10℃ was effective in maintaining freshness, and paprika packed in PP film maintained greater freshness than unpacked paprika. Our results showed that packaging is necessary to preserve the freshness and improve the marketability of paprika in the domestic market.

The objective of this study was to investigate the effect of nitrite substitution of sausage with purple sweet potato by examining the quality characteristics of sausage. Four sausage samples were prepared as follows: F1 (0.15% sodium nitrite), F2 (0.2% pigment), F3 (0.2% pigment and 5% powder), and F4 (0.2% pigment and 10% powder). A substitution of sodium nitrite with 0.2% purple sweet potato pigment reduced redness while increased yellowness. However, the addition of 5% purple sweet potato powder to 0.2% purple sweet potato pigment increased redness while reduced yellowness, which was similar to those of sausage with 0.15% addition of sodium nitrite. Further, color change increased as the content of purple sweet potato increased. As the amount of purple sweet potato increased, the contents of Ca, K, and Mg increased but hardness, gumminess, and chewiness decreased. In the sensory evaluation, the addition of purple sweet potato did not influence on appearance, color, or flavor. However, the addition of 10% purple sweet potato decreased the taste and texture of sausage. Correlation coefficients between overall acceptability, texture, appearance, color, taste, and flavor were 0.901, 0.895, 0.877, 0.844, and 0.688, respectively. Therefore, proper content of purple sweet potato powder and purple sweet potato pigment were determined to be 5% and 0.2%, respectively, for the substitution of sodium nitrite.
In this study, frying mix was prepared containing 0.5, 1.0, 1.5 or 2.0% brown rice fiber(BRF). The samples along with a control were then compared regarding their quality characteristics, including pasting properties, spreadability, pick-up ratio, color, textural characteristics, moisture and oil contents, and sensory qualities, all to determine the optimal ratio of BRF. For the pasting properties of frying mix, the control group was evidenced by a significantly higher peak viscosity, through viscosity, and final viscosity than that observed in the BRF samples. Breakdown was the highest at the 1.0% addition level, and time to peak viscosity and pasting temperature were maximal with the 0.5% addition. There was no significant difference in setback among the experiments. Spreadability and pick-up ratio of frying batter were not significantly different among the samples. As the BRF content increased, the lightness, greenness decreased, whereas yellowness increased. The BRF samples presented significantly higher hardness of fried batter than the control group and there was no significant difference in crispiness among the samples. Moisture content of fried sweet potato decreased with increasing BRF and oil content was the maximum on the control group. In the sensory evaluation, appearance, color, flavor, savory taste, yellowishness, coating thickness, off-flavor, and oiliness were not significantly different among the fried sweet potato samples. Bindingness, crispiness, and chewiness were highest in the control samples but minimal at a addition level of 2.0%. The control group evidenced significantly higher overall acceptability than were observed in the BRF samples. In conclusion, the results demonstrated that 0.5~1.0% BRF may prove quite useful as a additive for frying mix in the preparation of fried sweet potato and may provide favorable textural and functional properties.

This study investigated the properties of rice snack puffed in a microwave oven after drying its dough according to Baekjinju soaking time and additional soybean milk. The optimum conditions for the non-fried rice snack using Baekjinju wetted flour were determined through the design of an experiment using response surface methodology. The independent variables were the Baekjinju soaking time and the additional soybean milk, and the dependent variables were the weight, volume, density, expansibility, Hunter's color value, hardness, and sensory properties. The quadratic model was chosen for the weight, density, expansibility, b value, and hardness. The two-factor interaction model was chosen for the volume, flavor, appearance, and overall preference. The linear model was chosen for the L value, taste, and texture. The weight was increased to longer than 11.26 days with the increase in the rice soaking. The volume, expansibility, L value, and b value increased with the increase in the rice soaking time and in the additional soybean milk ratio. However, the density was decreased was in reverse. The hardness increased most, with the rice soaking time rising from 5.28 to 8.53 days and the soybean milk additional ratio increasing from 5.34 to 20.26%. The sensory properties improved as rice soaking time decreased, and the soybean milk additional ratio was revered. As for the desirability, the optimal formulation of the dough of non-fried rice snack was achieved by mixing 200 g of Baekjinju flour with a 0.69 days rice soaking time and a 26.67% soybean milk of rice ratio according to weight.
Consumers have become very conscious about their nutrition and well being due to changes in their socio-economic lifestyle and rapid urbanization. Therefore, development of technology for production of low cost and functional meat products is urgently required. One such approach is innovative restructuring technology in which binding of meat pieces still remains the main challenge and extension of product is generally associated with poor binding and texture. Thus, the present study was envisaged as an attempt to solve this problem by the incorporation of flaxseed flour (FF) as bind enhancing agent. The FF was used at three different levels viz., 0.5%, 1%, and 1.5% to replace lean meat in pre-standardized restructured mutton chops formulation. The products were subjected to analysis for physico-chemical, sensory and textural properties. Cooking yield, moisture percentage and fat percentage increased with increase in the level of incorporation of FF, however, protein percent and pH decreased with increase in the level of incorporation. Shear force value of product incorporated with 1.5% FF was significantly higher (p<0.01) than control and product containing 0.5% FF level. Among the sensory attributes, product with 1% flaxseed flour showed significantly higher values (p<0.05) for general appearance, binding, texture and overall acceptability. Hardness showed significant increasing (p<0.01) values with increasing levels of incorporation of flaxseed flour, however all other parameters of texture profile analysis showed a decreasing trend. On the basis of sensory scores and physico-chemical properties, the optimum incorporation level of FF was adjudged as 1%. Products incorporated with optimum level of flaxseed flour (1%) were also assessed for water activity and microbiological quality during the storage period of 15 days. It was found that the extended restructured product could be safely stored under refrigeration ($4^{\circ}C{\pm}1^{\circ}C$) in low density polyethylene (LDPE) pouches for 15 days without marked deterioration in sensory and microbiological quality. Thus, it was concluded that flaxseed flour can be used as a good bind enhancing agent in extended restructured meat products at an economic cost.
