Aloe is an attractive potential food source because it has functional uses. It has been widely used as a well-being food and drink. The antioxidant activity was estimated by measuring DPPH free radical scavenging activity. We investigated the quality characteristics of cookies prepared by adding various concentrations of aloe powder (0%, 1%, 3%, 5%, all w/w) as a substitute for flour. In this study, the DPPH free radical scavenging activity, moisture content, and hardness of cookies significantly increased with increasing aloe powder, while the pH, spread factor and L and b values slightly decreased. Sensory evaluation scores in terms of texture were shown to be very similar statistically, but color, flavor, taste, and overall acceptability scores were lower than the control. As a result of this study, the quality of cookies with the addition of 1% aloe powder were the most suitable in terms of taste, flavor, texture, and sensory properties.

The purpose of this study was to analyze the satisfaction level on hospital foods in elderly and middle aged patients. The subjects were selected among the patients treated in the Inha University hospital during July of 1999. One hundred thirty five elderly patients aged over sixty(68 men, 67 women) and sixty five patients aged in forties(35 men, 30 women) were surveyed through questionnaires in terms of satisfaction level on hospital foods and the food preferences. Satisfaction on general taste, saltiness, serving temperature, appearance, texture and variety of hospital foods was not significantly different according to age. However, elderly men showed significantly higher satisfaction level than elderly women in terms of general taste of hospital foods(p<0.01). The preferences of cooking method for meat, fish, vegetable and the preferred kinds of kimchi and milk & milk products were not significantly different between the two age groups. However, elderly women significantly preferred sauted meat to broiled meat compared to elderly men(p<0.05).

In this study, cod bone were used as the main ingredient of a stock that can be eaten with Korean dried noodles. The stock was produced with heating for 30, 40, 50, 60, or 70 minutes using high-pressure extraction methods. Moisture content, chromaticity, pH, sugar content, salinity, mineral contents, quantitative analysis, and overall acceptance were studied to determine the optimal heating time. In our result, S1 the showed highest water contents 98.10%, while S5 showed the lowest moisture content (97.47%). There were no significant difference in pH between samples, while salinity and sugar content increased with increases in heating time. In terms of mineral contents, sodium and potassium showed proportional difference with increases in heating time, however, magnesium, calcium, and iron did not change. The results from a quantitative analysis test showed that transparency, fishy smell, delicate flavor, savory flavor, salt taste, and umami taste became stronger with increases in heating time increase. From the above results, the overall taste of the stock increases with increases in high-pressure heating time. Specifically, S4 high-pressure heating scored the highest on appearance, flavor, taste, after-taste, and overall acceptance. Thus, 60 minutes of high-pressure heating time is most desirable when producing stock with cod bones as a main ingredient.

This study was conducted to determine the optimum amount of dried Alaska Pollock Therage chalcogramma roe (D-AP-R) for preparing garlic gochujang with D-AP-R. We investigated the optimal preparation of garlic gochujang with D-AP-R by proximate composition, taste, color, and odor measurements and sensory evaluation. The moisture, ash contents and water activity of garlic gochujang with D-AP-R decreased as the amount of D-AP-R increased, whereas other components, such as crude protein and lipid contents, taste value, yellowness of Hunter color, and odor intensity, increased as D-AP-R increased. According to the sensory evaluation results, garlic gochujangs with 10 and 15% D-AP-R were superior to garlic gochujang without D-AP-R (control) in terms of taste and overall acceptance but inferior in terms of fish odor. However, there was no difference in the sensual color of garlic gochujang with versus without D-AP-R. These results suggest that high quality garlic gochujang can be prepared by adding 10% D-AP-R. The total amino acid content of garlic gochujang with 10% D-AP-R was 11.81 mg/100 g, which was higher than that of the control (9.05 mg/100 g). The cholesterol content of garlic gochujang with 10% D-AP-R was 16.1 mg/100 g, which is below the acceptable daily cholesterol intake (300 mg/day).

The purpose of this study was to determine the most desirable mixture ratio of Maesil (Prunus Mume) concentrate torice flour for the preparation of Sulgidduk. The five different levels of Maesil (Prunus Mume) concentrate were 0%, 4%,8%, 12%, and 16% and were stored over 3 days. The results of this study were as follows. First, the water activity of Sulgidduk was significantly increased upon addition of Maesil(Prunus Mume) concentrate to rice flour. However, in terms of mechanical texture characteristics, the hardness of Sulgidduk was decreased, Maesil(Prunus Mume) concentrate was added to Sulgidduk. The control was $764.58{\pm}5.3\;g/cm^2$. Each amounts of added Maesil(Prunus Mume) concentrate to rice flour (4%, 8%, 12%, and 16%) resulted in hardness levels of $633.44{\pm}13.0\;g/cm^2$, $617.64{\pm}16.2\;g/cm^2$, $585.31{\pm}27.5\;g/cm^2$, and $350.98{\pm}10.2\;g/cm^2$, respectively. In addition, both gumminess and cohesiveness of Sulgidduk increased with increasing amounts of added Maesil (Prunus Mume) concentrate to rice flour. Regarding the color value of Sulgidduk, with added Maesil(Prunus Mume) concentrate the L-value decreased, while both a-and b-value increased. In the sensory evaluation, surface color, taste, and flavor were improved with increasing amounts of Maesil(Prunus Mume) concentrate, whereas texture decreased. Based on sensory evaluation, Maesil (Prunus Mume) concentrate resulted in intensified color, taste, and flavor of Sulgidduk. Consequently, 4% to 8% Maesil (Prunus Mume) concentrate to rice flour was determined to the best formula for improving Sulgidduk in terms of sensory qualities such as moistness, color, taste, flavor and so on.

The purpose of this study was to investigate the inpatients' perception of therapeutic-diets and of explanation about those diets provided by hospitals and satisfaction on therapeutic-diets at hospitals in Busan. The subjects consisted of 155 inpatients at five hospitals, which all had over 400 beds. The research was performed through the interviewing process using questionnaires. Seventy five percent of patients had received an explanation for their therapeutic-diet and 57.4% of respondents were given a manual that explained the reason for the therapeutic-diet. The professionals who explained the therapeutic-diet was 61.7% dietitians and 25.6% doctors. 59.4% of the patients considered the dietitian to be suitable for explaining the diet and 25.6% patients believed the doctor to be suitable for explaining the diet. In terms of the patients' perception of the therapeutic-diet explanation, 74.5% of the patients understood very well, 78.9% of them perceived this explanation as very important, and 67.5% of them were satisfied. On a scale of 5.00 for therapeutic-diet satisfaction, the average scores were 2.95 for meal characteristics and 3.06 for service characteristics. The items that scored low in therapeutic-diet satisfaction were taste, seasoning and appearance of meals, provision of selective menu and consideration of personal preference. In terms of the perception of understanding the therapeutic-diet, patients who were provided a manual and an explanation gave high scores to 'taste', 'variety of diet', 'meeting opportunity with dietitians', and 'prompt dealing with meal complications'. There was a significant (p<0.05) positive correlation between satisfaction for the explanation of the therapeutic-diet and the degree of perceived benefits of the explanation to the nutrition-management and the satisfaction on the therapeutic-diet satisfaction. Therefore, the results of this study suggest that hospitals should increase support for explaining the therapeutic-diet by dietitians and develop menus based on the patients' preference and the taste of the meal.

This study examined the dietitians 'perception and usage of processed meat products in institute foodservices. Out of 368 questionnaires collected from the subjects in school and business foodservices, 341 were chosen for statistical analysis after 27 were excluded for improper responses. According to the results, dietitian perceived the processed meat products food positively in terms of 'convenience'(3.94) and 'taste'(3.30), but negatively in terms of 'package'(275) and'additive'(2.01). In the frequency of usage, they used 'Ham'(2.51) the most frequently, followed in order by 'Wanja'(2.17), 'Dongas'(1.99), 'Tangsuyook'(1.82), 'Hamburg Steak'(1.71), 'Dduckgalbi'(1.59), 'Bacon'(1.50), 'Luncheon meat'(1.39), and 'Smoked meat'(1.30). The perception of processed meat products was more different according to institutes than dietitian. For dietitian, the frequency of usage was different according to their age and career, while for institute, it differed according to the type of management and the cycle of menu. Also dietitian placed the most importance on 'taste and preference'($90.1\%$) in buying and 'balance of nutrition'($72.0\%$) in cooking processed meat products (Ed- there is no respective comparison here). Finally, in the correlation analysis between perception and usage of processed meat products, the taste had positive correlation with 'Hamburg steak', 'Tangsuyook', and 'Dongas', the additive had positive correlation with 'Tangsuyook', and convenience had negative correlation with 'Tangsuyook' Based on the results of this study, the Processed meat products should be researched, developed, and supplied, with consideration for institution foodseuices.

This paper examines the dining tendencies of Koreans toward meat dishes and their related factors, with 301 people residing in Korea as subjects. We questioned this population on their restaurant choices, eating habits, preferences and a dislike with respect to method of cooking. All age groups, with the exception of 50~60 year-olds, were found to consume meat dishes in specialized restaurants. The selection factor for restaurants varied, depending on the age group: affordable cost was the most important factor for whom under 20 year-old. Whereas 20-40 year-old people considered taste and ambience the most for choosing restaurant. The 50-60 year-old people found to seek for convenient restaurant. In terms of the most preferred parts of beef, 20-30 year-old people preferred tenderloin (42.3%) while 40-60 year-old people preferred sirloin (45.6% and 41.2% each). All the other age groups preferred ribs the most (It was also found that) men preferred the rib parts and women preferred tenderloin. With respect to pork, all age groups preferred pork belly, with the highest response rate in the under 20 age group. When consuming meat dishes, 91.0% of respondents pointed to roasting as the most frequent preparation method, the reason being good taste was deemed the highest number of responses. In a survey on preference for stewed meats, 74.8% of the sample pool was found to prefer stew dishes but 24.9% of respondents provided negative answers, the reason for dislike was found to be poor taste for women, and both a long preparation time and poor taste for men. In fact, regardless of marital status, a high number of responses were given for poor taste as the reason for disliking stew dishes. Based on the examined factors for inconveniences in preparing meat dishes, the most common inconvenience factor was the odor of meat left on clothes after the dining experience, followed by the smoke generated in roasting meat, and the safety risk involved with changing the grill. In terms of stir fry preparation, the negative thoughts were due to the splashing of food and spices while cooking, followed by the meat odor left on clothes after dining experience, and the sanitation level of the cooking containers. For deep frying the sanitation level of cooking containers was the biggest reason for dislike, followed by splashing of food when preparing. Lastly, it was indicated that the problem of steaming method was a difficulty of judging the portion, on the top of this, people found that the sanitation level of cooking container and a long preparation time were also the problem of this cooking method.

This study was conducted to figure out the nutritional nature of seafoods categorized according to the medicinal effects and the usages introduced in Lim-Won-Sib-Rheuk.-Ji, one of the well-known encyclopedias published during the Chosun Dynasty. They were compared with those introduced in other cooking books in order to find out how they were used in the diet of real-life. The seafoods of the book were first categorized into the fish 20, the mollusk 5, the crustacea 4, and the shellfish 7, and reptile according to the biological taxonomy, and then each one was reviewed in terms of the taste and the food-nature. Generally, the fishes had the sweet taste; the crustacea and the shellfish the salty or sour in addition to the sweet taste; none of them were bitter or hot. Most of them had the mild nature; seven of them were regarded as warm; four as cool; one as cold from the standpoint of the traditional medicine. The food-nature of seafoods was closely related with the medicinal effects on the human body. These seafoods were characteristically used in daily dietary life as well as the medical applications; used as the side-dishes rather than the main-dishes. The cooking methods of boiling, steaming, and baking were preferred to drying and stewing. The preservation methods favored were the fermentation, drying and salting. These cooking and preservation methods were believed to reflect the nature of the seafoods to manifest the medicinal effects.
