In this study, the optimization of extraction parameters (solvent, temperature, time, solvent concentration) for the maximization of polyphenol extraction was performed to produce value-added food and cosmetic additives using a byproduct of coffee extraction process (coffee residue). All of the extraction parameters evaluated in this experiment had significant effects on polyphenol extraction and the results showed the effect of NaOH concentration on the polyphenol production was most significant among tested parameters. Especially, hot water extraction using acid or base was effective rather than hot-water extraction and the addition of 0.1 mol of NaOH increased 1.5 times extraction concentration compared with hot-water extraction using distilled water. It was found that hot-water extraction with NaOH was more effective than hot-water extraction, and 36.5 mg GAE/g DM was obtained under optimum condition of $100^{\circ}C$, 2 mol of NaOH and 30 min. This result was 2.9 times higher than that of 12.5 mg GAE/g DM obtained from the hot-water extraction before optimization. Thus, coffee residue could be used for food and cosmetic industry as a high-value additive such as antioxidant.

As competition in the domestic franchise industry is more heated than ever, we examined the factors that affect the profitability of the coffee franchise industry, which has grown rapidly over the last decade, and explored what effect preparatory startup education has on the profitability of coffee franchise stores. Specifically, this study looked into whether preparatory startup education can increase store competitiveness, provide insight into store location selection, generate innovative management, and ultimately contribute to store profitability. To test these hypotheses, we employed structural equation modeling. Results showed that preparatory startup education has a significantly positive (+)effect on 1)business characteristics: taste, quality, price affordability, menu diversity, store ambiance, 2)location characteristics: suitability, and 3)innovation management: accessibility, delivery service, and SNS marketing. The factors with a significantly positive (+)effect on store profitability were taste, quality, and price affordability with regard to business characteristics, suitability in terms of location characteristics, and SNS marketing in respect to innovation management. We expect that this study will have practical implications for increasing the profitability of coffee franchise stores, which are facing excessive competition, and its findings will be useful for coffee franchise head offices as well as government when making relevant policy decisions. In addition, it is intended to deliver a message to franchise head offices, central government, and local governments that they should provide institutional support to coffee franchise stores such that delivery services can lead to substantial improvement in profitability, even when delivery costs are considered.

In this study, Korean Hallabong produced in Jeju Island and coffee were grafted to prepare coffee containing Hallabong extract and the nutritional components were analyzed. As the amount of Hallabong extract increased, the water content and total polyphenol content increased. However, the crude flour, crude protein, and total flavonoid content decreased significantly. The selenium content per 100 g was 91.28 mg in the 1% Hallabong group, and the iron content was 6.84 mg in the 3% Hallabong group. As the content of Hallabong extract in coffee increased, the L-value (brightness) and b-value (yellowness) increased, but the a-value (redness) showed a tendency to decrease. In the case of DPPH(2,2-Diphenyl-1-picrylhydrazyl) radical scavenging activity, the group containing 9% of Hallabong extract showed the highest value at 47.20 μmol/g of TEAC. In particular, the ABTS(2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonate)) and DPPH radical scavenging activity were significantly increased from coffee powder containing 6% or more of Hallabong extract(p<0.05). The caffeine content decreased as the amount of Hallabong extract added to coffee increased. Therefore, when making powder coffee with Hallabong extract added, it is recommended to set the content of Hallabong extract to 6%.

Many industrial products such as paints, ink and adhesives are composed of the ingredients of a mixture. In mixture experiments, the characteristics of quality(response) depends only on the proportions of the ingredients and does not depend on the total amount of the mixture. This article discusses the constrained mixture experimental design, the data analysis, and the optimum formulation of ingredients based on the two quality characteristics - taste and flavor. It IS shown that efficient designs can be constructed from D-optimal criterion. Special cubic models were selected as the final mixture response surfaces for both reponses. The desirability function was used for the optimization of the two responses.

Modern society is living in material affluence after the Industrial Revolution. Meanwhile, consumer needs, in conformity with product diversification, are also being diversified. Modern consumers, unlike those of the past, are trending towards individual consumption that satisfies emotion and values instead of simple goal-oriented consumption. A model case is that of Starbucks. Starbucks has grown into the global coffee franchise it is today through emotional marketing that sells an atmosphere that is unique to Starbucks, consisting of store decorations, store music, employee service, and charming coffee aromas that are identical in every store anywhere in the world. Because this method is marketing that stimulates human emotion, it is assigned to and appeals to human senses and sensitivity. In other words, the charm of emotion marketing is that it draws out consumer emotion, produces positive reactions towards products, and leads to consumption. The utilization of emotions for products or service differentiates brand image and is becoming a key method in reinforcing brand royalty. In particular, more importance is being placed on customer service to strongly impress consumers. Intangible service is becoming the best way to impress customers.

큰 잘못을 하지 않아도 주기적으로 두들겨 맞아야 직성이 풀리는 제품이 있다. 커피자판기가 바로 그것. 최근 들어서 식품자동판개기가 위생점검 후에는 큰 잘못이 없어도 언론의 뭇매를 맞는게 늘고 있다. 민주 언론사회에서 과연 있을 수 있는 일인가 할 정도로 보도는 왜곡된다. 너무 선정적이고 사실무근이어서 울화가 치밀어 오르는 것도 모자라 헛웃음까지 날 지경이다. 지난 6월 13일 서울시가 발표한 식품자판기 점검결과를 보도하는 매스컴들은 똑 같은 작태를 따른 곳들이 많다. 산업계가 그러려니 침묵하기에는 너무 억울하다. 잘못된 보도로 인해 매출은 급락하고 자판기에 대한 소비자 시선은 싸늘해지는데 참고만 있기엔 억장이 무너진다. 지난 6월 중순 서울시 식품자동판매기 점검결과에 대한 왜곡된 보도, 과연 누구의 잘못인가? 따질건 따져보다. 먼저 서울시의 식품자동판매기 점검결과 보도자료를 그대로 살펴보자. 그리고 극명하게 왜곡된 SBS 보도 내용을 살펴보자. 많은 언론들이 SBS보도 내용 같은 보도를 일삼았다.
