Proper skin care promotes good metabolism and the biological activity of skin, helps maintain the skin in a healthy and beautiful state when combined with nutritional nourishment. Health functional foods are being used for the purpose of enhancing efficient skin care. Health functional foods related to skin care maintain the epidermis, dermal fibroblast layer and subcutaneous tissue that form the skin. Efficient functional foods alleviate the signs of endogenous aging that come with getting older and exogenous aging caused by sunlight. Even though the field of skin care related to health functional foods has received less attention and been the subject of less research compared to functional cosmetics which are developing widely, this area of skin care that maintains and improves the layer of dermal fibroblast through the intake of food, is expected to progress with the commercialization of products in many fields when the related technical research development is galvanized and the related patents are applied for. Research into health functional foods related to skin care in Korea started rather late in comparison to other advanced countries where patents for relevant techniques have been applied for since 1990's together with research conducted on how they might be used for practical purposes. This study used the key words 'skin care, health functional food' to search for Korean patents that have been applied for at the Korean Intellectual Property Office from 1983 to 2011 using the KIPRIS database, in order to help researchers in the related fields by organizing the patented formulas for health functional foods for skin care which have gained attention recently. According to the number of registrations in each industry field, the total number of patents was 1,120 we screened the major patents among them, the field with the largest number was food foodstuff non-alcoholic beverage and preparation or treatment(A23L) with 135, then natural plant medicine & medical supplies and cosmetics(A61K) with 112, microorganisms or enzymes(C12N) with 63, heterocyclic compounds(C07D) with 44, horticulture or cultivation of sea weeds, forestry(A01G) 16 times, listed from the highest to the lowest number of applications. It has been revealed that food, foodstuff, non-alcoholic beverage and preparation or treatment(A23L) was the industry field where the most patents for health functional foods related to skin care were registered.
This research intends to research on the optimal cooking techniques by adding perilla leaves to raw noodles, in which it has various effects and functions in sterilization. The water content measured in the dough added with raw perilla leaf juice came out high as more perilla leaves were added. More freeze-dried perilla leaf powder decreased water content. The pH of the dough increased significantly as the added ingredients increased with significant differences among the samples. The chromaticity of the dough deliberately decreased in both a and b as the amount of raw perilla leaves in dough increased. The L value of raw noodles with freeze-dried perilla leaves tended to decrease as more ingredients were added. The result of the RVA analysis on the dough with raw perilla leaves showed that the gluten decreased with more raw perilla leaves added. The result of the RVA analysis on the dough with freeze-dried perilla leaf powder indicated that the initial pasting tempo tended to increase significantly with more powder added except for 5% and 7% of powder added with no significant difference. The values dropped as the freeze-dried powder was added Minimum viscosity tended to decrease definitely as more freeze-dried perilla leaf powder was added. The dough's measurement results of WRC showed that water absorbing power of both dough with raw perilla leaves and that with freeze-dried perilla leaf powder reduced significantly as more perilla leaf powder were added.
The chemical components of four muskmelons (Thankyou, Beauty, Picnic, and Symphony), according to the cultivars, were investigated during storage at $7^{\circ}C$ for 28 days. After the storage period, the Picnic cultivar indicated a weight decrease of up to 4.70% whereas the Symphony cultivar showed the best weight maintenance during storage (1.02%). The Thankyou and Symphony cultivars had higher sugar content and acidity levels than the Beauty and Picnic cultivars during storage. While the Symphony and Beauty cultivars showed high hardness at the start of their storage, their hardness decreased much during storage while the Thankyou and Picnic cultivars showed little change in hardness during storage. Further, the Thankyou cultivar not only maintained its unique muskmelon yellow color but also showed lower microorganism growth than the other cultivars. The stem water loss seen in this cultivar, however, tends to be the first thing seen by the consumers and may thus determine its merchantable quality. In addition, as the Thankyou cultivar showed the least quality change during storage, it will be useful for the development of a technology for minimizing the moisture content of a muskmelon's stem.

The purposes of this study were to investigate the current status of contracted hospital food services and to find out the difference in accordance with the number of beds in hospitals. Thirty six hospitals having more than 100beds in Seoul, Inchon and Kyungkido were the subjects of this study. Data was collected through surveys. The survey was conducted during March and April in 2002. The Questionnaires were mailed to the 36 directors of dietetic departments of the hospitals and 36 managers of contracting patient food services. Statistical analysis was completed using SPSS Win(11.0) for descriptive analysis and t-test. The results of the study are summerized as follows; Ⅰ. Hospital perspective : The range covered by contract food service was 63.3% and 36.7% in hospital food services, and medical nutrition services. The patient and employee food services were in 83.3%, and patient food services were in 6.7%. The methods selecting contractors are general, limited, selected and competitive biddings, and private contracts. The responsibility for supervision of contract food services was the dietetic department (51.7%) in most cases. Hospitals having personnel responsible for contracting affairs were in 75.9% of the cases and 24.1% did not have personnel. The biggest reason for contracting was facilitation of personnel management. The most important criteria on selecting food services contractors was the professionality of the contractor. Ⅱ. Contractor's perspective : The cost per meal in the year 2001 was composed of 1,905 won for food cost, 1,081 won for labor cost, 222 won for expenses, 114 won for VAT, 14 won for rent and 146 won for miscellaneous or controllable expense, representing 109 won loss per meal. The profit-and-loss contract cost is higher than the fee-contract cost. The ratios of food cost, labor cost and expenses are higher and the ratios of miscellaneous or controllable expense, VAT, rent and profit are lower in hospitals with more than 400 beds compared with those less than 400 beds. However, no significant differences are present between these two groups of hospitals. The actual contract period was 2.2 years upon initial contract and 1.2 years upon renewal. The initial investment cost was 53 million won and the cost of renovation and repair was 8.5 million won. Significant differences were present between two groups of hospitals. The conditions of employment and number of personnel hired by contractors for contract patient food services were significantly different according to the number of beds.
This study investigated the effect of bamboo leaf powder, added at content of 0%, 3%, 6%, 9% and 12%, on the quality and sensory characteristics of rice cake imprinted with flower pattern (Ed-there is no respecitive comparison here) The chemical composition as a whole was 3.07${\pm}$0.12% of moisture, 5.87${\pm}$0.02% of crude protein, 2.52${\pm}$0.05% of crude fat, 23.70${\pm}$0.07% of crude fiber and 7.73${\pm}$0.02% of crude ash. With increasing amount of added bamboo leaf powder, the hardness and chewiness of the cake were significantly increased(p<0.05), while the cohesiveness, springiness and adhesiveness were decreased. In chromaticity, the L-value, the indicator of brightness, was significantly decreased with increasing bamboo leaf powder content. The a-value, the indicator of redness, was significantly lower than the chlorophyll color (p<0.05). The b-value, the indicator of yellowness, was increased indirect proportion to the content. In sensory test, the sensory characteristics such as color, flavor, taste and chewiness were all stronger with increasing powder content, whereas the softness and dampness were weaker. The greatest overall satisfaction was achieved by the sample group of cake with 6% preference added powder.
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.
The objectives of this study were to analyze the physiological and antimicrobial activities of wheat germ. The fatty acid components of the wheat germ included palmitic, stearic, oleic, linoleic, and linolenic acids. Furthermore, the acid value was 8.5, the peroxide value was 7.1, the iodine value was 126.8, the saponification value was 159.7, and the refractive index was 1.547. In the unsaponifiable matter, the total phenol concentration extracted by ethanol, along with physiological activity were 2.02% and 0.45%, respectively, and the amount of flavonoids and activity were 6.89% and 6.90%, respectively. The amount of flavonoids was larger than the phenol concentration in the wheat germ. In addition, the nitritescavenging ability of the wheat germ was lower than ascorbic acid but greater than BHT and tocopherol. The peroxide value in the linoleic acid changed over 5 days, presenting as 0.67, 22.70, 44.25, 5.81, and 91.17 meq/kg, and increases were also consistently shown as time passed for the ethanol extractions and unsaponifiable. Additional data showed that antimicrobial effects could not be detected in the wheat germ concentration or method of extraction.
This study is designed to examine influences of living arrangements on psycho-social factors, health and nutritional status, dietary adequacy and meal service utility patterns of the elderly. Nutritional status was evaluated by Mini Nutritional Assessment (MNA). Three hundred and nine elderly (110 men and 199 women) who participated in meal service in the Chung-buk province were investigated. Proportion of the elderly living alone, couples only, living with spouse and family, living with family without spouse; and living with other than family were 30.7%, 25.9%, 14.2%, 24.3% and 4.9% respectively. The mean age of the elderly was 74.1 years and the elderly who are living couples only and living with spouse and family were younger than those with other living status. Living arrangements seem to be related to psycho-social factors, health and nutritional status, and dietary quality. Those who live alone and live with other than family were mostly women and they have lower socio-economic status, psycho-social, health and nutritional status and dietary patterns compared with those of the elderly who are living with spouse or family. It was found that the elderly who live a couple only and live with spouse and family had better emotional, health and nutritional index than those of the elderly who live with family without spouse, especially in case of females. Most of elderly perceived that participation of meal service programs had a positive effect on their daily life and satisfied with meals. The elderly living alone and living with other than family were more frequently using meal service but had a negative attitude about the charged meal service for better quality than the elderly with other living status. The most important reason for all the elderly to participate in meal service was to meet their friends and then to get other services. Particularly those who are living alone and living with other than family showed lack of moivation to prepare and set the meal, and for them the economic reason is also important. They also replied that the poor health and lack of other help were the most difficult problems for them to prepare meals. It would be effective to provide nutritional services that meet specific needs of the elderly according to their characteristics and living environment.
The purpose of this study is to decide the optimum amount of ginger, which draws attention as a functional food nowadays, to make ginger muffins and to serve the basic data for functional bakery products added with ginger juice. As measurement items for quality characteristics, I tested height, weight, volume, specific volume, moisture, pH, chromaticity, texture and organic functions of muffin by adding 10%, 20% and 30% ginger juice respectively comparing with general ingredients plus water amount used to make muffins. Height decreased with the amount of the addition increased, and there was no significant difference in weight. The volume and specific volume measurements of the muffins showed a lower value with the amount of the addition increased, which showed a significant difference. The moisture contents of the muffins increased with the amount of the addition increased. In the pH measurement, 0, 10, and 20% showed no significant difference while 30% showed a significant difference. Color measurement found that lightness and yellowness decreased with the amount of the addition increased, which showed a significant difference; redness showed high values, which indicated significant differences among all the samples. Texture measurement found that hardness showed significant differences among all the samples; cohesiveness showed a significant difference between the control and the treatment group; resilience/springiness increased with the amount of the addition increased. There were no significant differences in gumminess while chewiness increased with the amount of the addition increased. The sensory evaluation showed the lowest color with the amount of the addition increased; 10% addition was most preferred in flavor and taste; there was no significant difference in texture; there was no significant difference in 0, 10, 20% additions in overall acceptability. Taking the quality assessment and the sensory evaluation together, it is considered that general tastes of ginger muffins can be improved when ginger juice addition is 10% of water amount used.
