This study was conducted to effectively supplement vitamin D and increase the consumption of ear mushroom based on the investigation of the quality characteristics of cookies containing ear mushroom supplemented with vitamin D. Cookies were made of 0%, 1%, 3%, and 5% ear mushroom powder treated by ultraviolet B. Increased addition of ear mushroom powder led to a decrease in the bulk density of the dough as well as a spread factor, color value, and hardness of the cookies. There was no significant difference in the loss rate, but the water content of the dough and cookies was increased. The total polyphenol content of cookies added with 1~5% ear mushroom powder was higher than that of the 0%. The DPPH free radical scavenging activity of cookies added with 5% ear mushroom powder (23.8%) was 2 times higher than that of the 0% (10.9%). The vitamin D2 content of cookies added with 5% ear mushroom powder (835.5 ㎍/100 g D.W.) was 44 times higher than that of the 0% (19.0 ㎍/100 g D.W.). Consequently, ear mushroom powder is considered to be suitable for the production of functional cookies because of high values of antioxidant activity and vitamin D2 content.

This case focuses on WE CAN Cookies, a social enterprise in South Korea that was founded in 2001 with the support of the Korean Roman Catholic Church. WE CAN Cookies specializes in the making of high quality organic cookies. As a nonprofit organization that uses a labor force of mostly mentally disabled workers, the company faces many challenges that normal companies do not experience. The company had to initially overcome the social prejudice that the handicapped cannot make good cookies. Despite the religious background and social agenda of the company, it started making inroads as a cookie-making business only after its managers, including the nuns who run it began adopting modern management philosophies and practices. The WE CAN Cookies case illustrates three main marketing-related concepts: One, WE CAN Cookies is a good example of how social enterprises face a broader spectrum of challenges when compared to conventional profit-seeking enterprises. Two, WE CAN Cookies demonstrates that social enterprises need flexibility in formulating their business strategies. Even though WE CAN Cookies is subject to many constraints, as a social enterprise it can also take advantage of new opportunities for obtaining support from the government and from the private sector. Three, WE CAN Cookies shows that these types of operations need to create greater balance in their social and business competencies to ensure the long term viability. Social enterprises are certified by governments with the stated goal of improving the lives and the wellbeing of special interest group. As important as achieving these objectives are, social enterprises also must additionally be able to build their operational capabilities not only in manufacturing but also in functions such as marketing.

The purpose of this study was to find out the information on nutrition labeling and how many calories and nutrients the high school students consumed for 1 day from cookies. A total of 74 male and female high school students in Suwon were surveyed and 56 cookies that they consumed were examined. Background data were collected by questionnaire, cookie intake by 24-hr recall, and the calories and nutrients content in cookies and the amount of intake by nutrition information on the wrapping paper of cookie. The statistical analysis for the data was done by SPSS 12.0. Energy contents in 1 serving size of cookie were $90{\sim}315\;kcal$, average of 170 kcal. The protein contents were $0{\sim}7\;g$, fat $2{\sim}20\;g$, cholesterol $0{\sim}55\;mg$, and sodium $30{\sim}390\;mg$ in 1 serving size of cookie. Most of the cookies(80%) examined contained no trans fat at all, which is desirable. Among the types of cookies, snacks contained higher quantities of calories and sodium, the pie contained more sugar and cholesterol, and the biscuit had more trans fat. One fourth of the cookies examined belonged to 'high calorie, low nutritious food' according to the criteria proposed by The Ministry for Health, Welfare and Family Affairs. Thus the excessive intake of cookies might result in nutritional imbalance. There were large differences in calorie intake among students, from zero who did not intake any cookies at all to maximum 818 kcal/day, an average of 75 kcal/day. When the students who did not intake cookies were excluded, energy 205 kcal. fat 10 g, sodium 177 mg were consumed from the cookie for a 1 day on average.

This study was conducted to investigate the effects of adding gochujang addition to cookie dough on the quality characteristics of cookies. Cookies were prepared by replacing 0% 5%, 10%, 15% and 20% flour with gochujang. The gochujang pH, total soluble solid and salinity were $4.84{\pm}0.02$, $63.33{\pm}4.19%$ and $7.63{\pm}009%$, respectively. The moisture content in gochujang was $40.10{\pm}0.10%$, and the color values of gochujang was were as L-value $24.46{\pm}0.06$, a-value $10.18{\pm}0.13$, and b-value $7.44{\pm}0.10$. The pH values of cookies decreased according to the addition of gochujang. The values of density and loss rate in cookies were not-significantly different among the samples. Spread factor and moisture content of cookies increased with amounts of added gochujang. The salinity and total soluble solid content of cookies with gochujang were significantly higher than those of the control. L-value was significantly reduced, and a-value and b-value increased by adding gochujang. Total phenolic content and DPPH free radical scavenging activities were increased according to the amount of gochujang. For sensory evaluation, gochujang added cookies were more preferred in terms of color, softness and overall preference. Overall, these results indicate that adding 10% gochujang is desirable for making gochujang cookies.

Traditionally, the persimmon Gojongsi (Diospyros kaki Thunb) is peeled to make dried persimmons and the skins are thrown away. In this study, the quality characteristics of cookies containing persimmon peel powder were tested for recycling of the persimmon peels. The amounts of persimmon peel powder added to the cookies were about 0, 5, 7, 9 and 11%. The densities of the cookies of the control group and the persimmon peel powder containing experimental group were 1.25 and 1.25~1.37 respectively. The pH was 6.02 for the control group and 5.95~6.01 for the experimental group. Significant differences in the moisture content were observed between groups at 3.34 and 2.16~3.31 for the control and experimental groups, respectively (p<0.05). The spreadabilities and loss rates of the cookies increased with increasing amounts of persimmon peel powder (p<0.05). In contrast, the loss rates and leavening rate of the cookies decreased significantly with decreasing amounts of persimmon peel powder (p<0.05). The lightness of the cookies showed significant decrease (p<0.05), while the redness and yellowness increased with increasing amounts of persimmon peel powder. The hardness (kg) of the control group was 0.847 while that of the experimental group was 0.904~1.110. In the QDA, the results of sensory characteristic analysis showed that the experimental group earned 11% higher scores for color, flavor, taste, and bitterness, 7% higher for appearance and 9% higher for after taste. The consumer acceptance test revealed the experimental group to have a 7% more positive evaluation for color, favor, taste and texture than the control group. On the grounds of the experiment above, the optimal mixture ratio from the sensory test was found to be 7% persimmon peel powder in the cookies.
