This study was conducted to investigate the effects of saltwort, on the quality characteristics of sponge cake. In addition, we examined the commercialization potential of sponge cake containing saltwort. To accomplish this, saltwort was added to sponge cakes at concentrations of 0%, 3%, 5% and 7% and quality and sensory tests were then conducted. The 7% group had the highest water and ash content. There was no difference in the fat content between samples. The control group showed the highest protein content and the lowest specific gravity. As the content of saltwort increased, the specific gravity of the sponge cake increased. Additionally, the dough yield and loss during baking were highest, in the control group, and these values decreased as the saltwort content increased. Similarly, the volume and specific volume were highest in the control group, and these values decreased as the content of saltwort powder increased. Color measurements of the samples, revealed that the L-value decreased as the content of saltwort powder increased. Furthermore, the a-value of the saltwort powder groups was higher than that of the control group and the b-value was highest in the 7% group. There were no differences in elasticity and cohesion between samples, but chewiness and brittleness increased the content of saltwort powder increased. The results of the sensory test revealed that the color, flavor and taste scores were the highest in the 5% group. The pore size was greatest in the control group, while hardness was greatest in the 7% group, chewiness was highest in the 5% group and moistness was highest in the 5% group. Finally, the overall preference was for the 5% group.
This study was carried out to investigate the mechanical and sensory properties of Teriyaki sauce made with different boiling time(6, 8, 10 and 12 hrs). The results were as follows. As for the mechanical characteristics, moisture contents, L-value, a-value, salinity and pH decreased with increasing boiling time. On the other way, viscosity, b-value and sugar contents of Teriyaki sauce increased with increasing boiling time. From results of quantitative descriptive analysis, offensive flavor was significantly different when examining Teriyaki sauce alone, but there was no difference when the sauce was accompanied with food. The 8 hr-boiling sauce was favored most in chicken with Teriyaki sauce, and 10hr-boiling sauce was favored most in eel.
In this study, the physicochemical and sensory characteristics of low-salt Myungran jeotkal (Alaskan pollock roe) were evaluated after fermentation at $4^{\circ}C$ and $20^{\circ}C$ with or without the addition of deep sea water, salt from deep sea water, and vegetable-origin lactic acid bacteria (Lactobacillus fermentum JS, LBF). When fermented at $20^{\circ}C$, the addition of LBF to Myungran jeotkal resulted in a slow increase in lactic acid content, followed by an abrupt increase after five days of fermentation. However, when fermented at $4^{\circ}C$, the lactic acid content did not change significantly. Further, when Myungran jeotkal fermented at $4^{\circ}C$, the pH decreased as lactic acid production increased. The salinity of Myungran jeotkal fermented at $4^{\circ}C$ and $20^{\circ}C$ was 7% and was not affected by fermentation period. When fermented at $20^{\circ}C$, volatile basic nitrogen and amino nitrogen contents increased with increasing duration of fermentation. Further, volatile acid content decreased, however, the content of amino nitrogen increased after 11 days of fermentation with LBF and no salt effects were observed. When fermented at $20^{\circ}C$ for 13 days, preference (sensory evaluation) was the highest in all experimental groups after 9 days of fermentation, and then decreased as the fermentation period increased. The free amino acid content was highest (1,648.8 mg/100 g) in Myungran jeotkal when sun-dried salt and LBF were added, 2.3 times higher than in the control.
Objectives Meal and nutrition are important lifestyle factors that affect maintenance and promotion of health status and are also associated with chronic diseases. In Sasang constitutional medicine, dietary behavior according to the characteristics of Sasang constitution (SC) types is a key component in health management. The aim of this study was to evaluate the nutritional status and quality of meals according to the SC. Methods This was a cross-sectional study of 1,947 subjects surveyed in a community-based cohort called the Korean Medicine Daejeon Citizen Cohort study. Data were collected including demographic characteristics, Korea Sasang Constitutional Diagnostic Questionnaire, and nutrition quotient (NQ) for adults. We analyzed the differences in NQ grade and scores among three SC types: Taeeumin (TE), Soeumin (SE), and Soyangin (SY), by conducting chi-square and ANCOVA tests. Results The distribution of SC into TE, SE, and SY types was 43.1%, 25.2%, and 31.8%, respectively. The mean NQ score of all subjects was 53.4±8.6. There was a significant difference in the distribution of NQ grades and mean of NQ scores among SC types, including total and four sub-factors: balance, diversity, moderation, and dietary behavior. The TE type had the lowest score for the moderation factors in the crude model. The SE type showed lower NQ scores than the TE and SY types in all domains except moderation after adjusting for variables. Conclusions We found that dietary behaviors had to be distinct according to the SC types. These results elucidate why it is important to develop a customized dietary habit management program considering the SC types.
The general composition like moisture content, and the physical and sensory characteristics of the steamed rice cake added with powder of roots of balloonflowers were as follows. The moisture content in the roots was 4.13${\pm}$0.01%, crude protein 9.24${\pm}$0.11%, crude fat 3.07${\pm}$0.04%, crude fiber 33.82${\pm}$0.01%, and crude ash 8.16${\pm}$0.02%. The moisture content of the cake was decreased with increase of the root’s powder added. In physical characteristic, the hardness of the cake was increased with increase of the powder. The control cake was the highest in the cohesiveness. The springiness tended to be increased with increase of the powder. The gumminess was higher with increase of the powder, being 530.33% in the control and 284.44% in the sample with 12.0% powder added. The adhesiveness was decreased with increase of the powder. The color change was significantly decreased with increase of the powder. With increase of the powder, the value a was decreased, while the value b showed to be increased. In a sensory test, the favorite degree to color, flavor, bitter taste, moistness, soft-ness and overall acceptability was measured to get the follow result. To color, the lot with 6% of the balloonflower powder added showed the highest accept-ability with the same highest result also to flavor and bitter taste. The moistness and the softness were revealed as the highest at the control, and the chewiness was also highest at the lot with 3% of the powder added. The overall acceptability was highest as 5.75 at the lot with 6% of the powder added, coming out to be higher in order of the 3% added-lot, the control, the 9%-lot and the 12%-lot.

Low-fat, precooked high quality Wanjajun was prepared by treating natural antioxidant herbs and hydrocolloids for quantity production of cook/chill system in foodservice. The proposed Wanjajun was formulated under the consideration of flavor and fat level. Wanjajun was prepared with hydrocolloid such as sodium alginate, car-boxymethyl cellulose (CMC), carrageenan and xanthan gum. Cooking yield, fat retention and water holding capacity of Wanjajun containing hydrocolloidal gums were higher than those of control. L-value of raw product was low in comparison with cooked product, but a-value was higher than that of other cooked product. Colors of raw and cooked products were not different among five kinds of products. pH value of cooked product was higher than that of raw product pH range of cooked products revealed to 6.10~6.23. There was no considerable change in pH value during storage. The coliform group and Staphylococus aureus were not detected during storage. Total bacteria1 counts were close to microbial guidelines for safe condition. Hardness, springness, cohesiveness, gumminess and brittleness of low-fat products were generally lower than those of control product. Hardness, gumminess and brittleness of reheated products were higher than those of preheated products. Flavor, tenderness, juiciness and overall quality were not different between precooked and reheated products. Textural characteristics of products were superior in the order of sodium alginate, xanthan gum, CMC, carrageenan and control product.
To meet the needs of Muslim consumers, sausages were prepared using Halal-certified chicken thighs and different amounts of biji powder (0, 20, 30, 40, and 50%), and then the properties of the sausages were compared. As the biji powder levels increased, both the moisture content and the pH of the sausages significantly decreased, whereas their fiber content increased. As the biji powder levels increased, the free radical scavenging effect (DPPH, ABTS) and water holding capacity also increased, and the textural properties also improved. When Muslim consumers evaluated the sensory attributes of the sausages prepared in this experiment and those currently on the market, the ones prepared in this experiment were preferred over the market products. Based on the above results, chicken sausage for Muslim consumers could be successfully produced, and their overall quality and antioxidant effects could be improved by the addition of biji powder (up to 30%).
The purpose of this study was to investigate the quality characteristics of sponge cake with broccoli (Brassica oleracea var. italica Plenck) powder. Broccoli powder was mixed with wheat flour at various ratio (3, 5, 7, 9%, w/w) for physical and sensory evaluations. The specific gravity of bread dough increased with added broccoli powder. The moisture of the sponge cakes with added broccoli powder was higher than that of control. In the crumb color values, lightness (L) and redness (a) decreased upon broccoli powder addition, whereas yellowness (b) significantly increased (p<0.05). In the texture analysis hardness, cohesiveness, springiness and gumminess were reduced by addition of broccoli powder. When we evaluated the sensory characteristics of five subareas (color, flavor, texture, taste, and overall acceptability), 7% broccoli sponge cake showed the highest sensory properties except for flavor (p<0.05). Therefore, the results suggested that 7% broccoli sponge cake could be helpful in improving physical quality and taste.

Objectives: This study was performed to identify the current barriers of obesity management for children using Community Child Care Centers and their caregivers (parents and teachers working in the Centers). Further, this study explored the possibility of utilizing a mobile phone application for tailored obesity prevention and management programs to overcome the current difficulties associated with children's obesity management. Methods: The qualitative data were collected through in-depth interviews with 20 obese and overweight children or children who wanted to participate in this study using Community Child Care Centers, 12 teachers working at the Centers, and a focus group interview with five parents of children using the Centers. Data were analyzed with a thematic approach categorizing themes and sub-themes based on the transcripts. Results: The current barriers of obesity management of obese and overweight children using Community Child Care Centers were lack of self-directed motivation regarding obesity management (chronic obesity-induced lifestyles and reduced self-confidence due to stigma) and lack of support from households and Community Child Care Centers (latchkey child, inconsistency in dietary guidance between the Center and household, repetitive pressure to eat, and absence of regular nutrition education). Mobile phone applications may have potential to overcome the current barriers by providing handy and interesting obesity management based on visual media (real-time tracking of lifestyles using behavior records and social support using gamification), environmental support (supplementation of parental care and network-based education between the Community Child Care Center and household), and individualized intervention (encouragement of tailored and gradual changes in eating habits and tailored goal setting). It is predicted that the real-time mobile phone program will provide information for improving nutritional knowledge and behavioral skills as well as lead to sustainable children's coping strategies regarding obesity management. In addition, it is expected that environmental factors may be improved by network-based education between the Community Child Care Centers and households using the characteristics of mobile phones, which are free from space and time constraints. Conclusions: The tailored education program for children using Community Child Care Centers based on mobile phones may prevent and reduce childhood obesity by overcoming the current barriers of obesity management for children, providing environmental and individualized support to promote healthy lifestyles and quality of life in the future.
This study was conducted to evaluate the effect of various types of functional brown rice milk porridge, which has been popular as a fast yet nutritional food, to promote rice consumption and to examine the best ratio and recipe. Each sample contained 10, 20, 30, and 40% brown rice compared to non-glutinous rice and sweet rice and were applied to mechanical and sensory tests. The moisture content of both non-glutinous rice and sweet rice porridges increased with increasing brown rice content. The viscosity of non-glutinous rice milk porridge decreased as with increasing brown rice content, whereas the viscosity of sweet rice milk porridge increased with increasing brown rice content. The pH was highest for BRT0 at 6.74 and lowest for BGT0, which is sweet rice porridge with brown rice, at 6.27. The sweetness decreased significantly for both sweet rice and non-glutinous rice porridges with the increase in brown rice content. The brightness of weet rice and non-glutinous rice porridges with brown rice increased significantly (p<0.001) with the increase in brown rice content, while the redness and yellowness of the color increased significantly (p<0.001) with increasing in brown rice content. As a result of analyzing the preference in the milk porridge containing brown rice, BRT30, which is non-glutinous rice milk porridge with brown rice, was most preferred at 5.8 in terms of color, while BRT30 was most preferred at 6.2 in terms of fragrance. All samples containing brown rice powder were highly preferred in terms of taste and the overall preference of sweet rice milk porridge was highest for BRT30 (5.8). The overall preference was highest for BGT30 at 6.1 and the preference was generally higher for the experiment groups prepared with sweet rice as opposed to those prepared with non-glutinous rice. Also, the scores for the sensory test were higher when brown rice was added. Therefore, it was concluded that the milk porridge could quickly and easily be prepared with brown rice instead of non-glutinous rice or sweet rice.
