21세기에는 유전자조작기법을 통해 젖소가 기름기 없는 우유를 생산하고 카페인 없는 원두커피가 나온다. 또 썩는 플라스틱의 원료도 식물을 통해서 얻고 구겨지지 않는 천연섬유도 선보인다. 또 바다에는 해양목장이 들어서서 지능높은 돌고래를 훈련시켜 관리를 맡긴다. 넓은 사막엔 바닷물을 끌어 올려 농사를 지어 우리의 부족한 식량을 충당하게 되고 꽃 냄새와 꽃의 색깔도 마음대로 조정하여 밝고 풍요로운 신세계가 전개된다.

해외도입붐-. 그 물결을 타고 많은 외국기업들이 상륙했다. 크게는 자동차의 GM과 Ford, 석유의 걸프와 칼텍스등 이른바 $\ulcorner$세계기업 $\lrcorner$으로 불리우는 거상에서 가까운 일본의 이름 없는 중소기업에 이르기까지 다양하다. 이들은 해외시장개척과 현지생산의 메릿트를 찾아 줄이어 밀려닥치고 있다. 식품산업이라고 예외는 아니다. 기술제휴로 진출한 코카콜라와 펩시콜라가 시장쟁탈전을 벌이고 있고 맥스웰$\cdot$하우스$\cdot$커피의 제네럴$\cdot$푸우드(GF)도 합작투자로 상륙, 자리를 굳혔다. 이제 외국기업이라해서 아주 우리의 관심밖일 수는 없게 된 것이다. 여기 해외진출전략을 중심으로 세계식품메이커의 최근 동향을 알아본다.

집속초음파 추출법(Innovative Extraction by Focused Ultrasound, INEFU)은 기존의 추출법에 비교하여 식물세포벽으로부터 기능성 성분을 낮은 온도에서 높은 추출 효율을 얻기 위한 추출공정으로 적용하기 위하여 연구되고 있다. 본 연구에서는 그린커피빈(COFFEA ARABICA SEED)에서 Chlorogenic acid, Caffein, Caffeic acid의 기능성 성분 추출을 위해 INEFU를 적용하여 추출 효율에 미치는 요인을 평가하였다. 추출 변수의 최적화를 위해 추출 온도 및 추출 시간을 요인으로 하여 순차적인 최적화를 진행하였다. 동일한 추출조건에서 저온추출(CEM)과 INEFU를 비교하였을 때 INEFU에서 Chlorogenic acid, Caffein이 각각 2.1 와 2.2배 증가함을 확인하였다. 또한 Caffeic acid는 저온추출(CEM)에서는 추출되지 않았으나, INEFU에서는 추출되는 것으로 확인하였다. 본 연구를 통해 INEFU가 기존의 추출 공정에 비해 기능성 성분 생산에 보다 효과적임을 확인하였다.

For the purpose of obtaining microorganisms producing high fructosyl transferase, the screening test was carried out. Among more than three hundred isolates, an isolate (C23-isolate) was selected for high fructosyl transferase producer from the dirts at the coffee vendig machine. The morphological and cultural characteristics of the isolate C23 on various culture media were studied and identified as Aureobasidium pullulans var. melanigenum.

This study was performed to survey and evaluate the contents of pH, total acidity, caffeine, harmful metals (Pb, Cd) and total polyphenol in coffee extraction. In total, coffee bean. Total fifty coffee samples were analysed. A 5 g portion of roasted ground coffee samples were extracted in coffee-maker with 100 mL of distilled water and the extraction were used in all experiments. The pH range was 4.72~5.25 (mean value = 4.99). According to increase of the roasting temperature, the pH were shown a tendency to increase. The contents of total acidity was 0.72~2.25% (mean value = 1.59%). According to increase of the roasting temperature, the contents of total acidity were shown a tendency to decrease. The contents of harmful metals (Pb, Cd) in coffee extractions were determined by ICP. The average contents of Pb and Cd were 0.0112 and 0.0011 mg/kg, respectively. The contents of caffeine in coffee extractions were determined by HPLC, the range of detection was 0.51~20.28 mg/mL (mean value = 12.29 mg/mL). According to increase of the roasting temperature, the contents of caffeine were shown a tendency to increase. The contents of total polyphenol in coffee extractions were determined by spectrophotometer, the range of detection was 18.88~43.90 mg/mL (mean value = 31.94 mg/mL). According to increase of the roasting temperature, the contents of total polypenol were shown a tendency to decrease.

An experimental study on the automation of the coffee roasting process was conducted. For this study, a temperature sensor, controllers, and motors were added to a manually operated coffee roaster. The temperature, time, and exhausting damper control were selected as the control parameters. The thermocouple measurements were severely influenced by the thermocouple size and location of the roaster. As a result, the standard thermocouple size and location of the roaster were experimentally set to show a similar trend of temperature change by using a previously installed thermometer. A standard roasting process was chosen through repeated roasting experiments and the advice of a roasting expert. The automation of the roasting process was successfully executed using temperature criteria, such as the bean input and first and second crack occurrence, and by controlling the exhausting damper opening time. The control parameters and roaster skills can be used for similar types of roasters for process automation.

자판기 생산업체가 없어 전량을 수입에 의존하고 있는 러시아 모스크바를 중심으로 자판기 설치가 대중화되고 있어, 향후 최고의 비즈니스 아이템으로 부상하고 있다. 러시아에서 다수를 차지하는 자판기 정류로는 커피자판기와 캔자판기로 95% 이상이 모스크바에 집중돼 있는 것으로 나타났는데, 모스크바의 경우 자판기 설치대수는 유럽의 5%에 불과하며, 자판기 1대가 약 1,600명꼴로 보급이 되어 있는 반면, 유럽은 1대당 평균 134명 꼴로 보급되어 있는 것으로 나타나 향후 전망이 매우 밝은 것으로 예상된다. 전문가들에 의견에 따르면 러시아 자판기 시장 잠재력은 매우 커 향후 5년간 자판기 판매 금액만 연간 1억 4000만달러, 자판기를 통한 음료수 판매액은 연간 10억달러에 달할 것으로 전망하고 있다. 한편 러시아에 수입괴고 있는 자판기 대수에 대한 정확한 수치는 나와 있지 않지만, 수입통계 및 전문가들의 의견을 고려해 볼 때 모스크바에만 약 5000대의 자판기가 설치돼 있는 것으로 추정된다. 그러나 이들 자판기중 30%는 코카콜라가 제공하고, 10%는 네슬레사, 그리고 펩시콜라, TetraPak사 등이 공급한 것으로 나타나 일반적인 자판기 시장의 확대 여지는 큰 것으로 분석되고 있다.

This article describes the application of discrete event simulation in a process industry (coffee manufacturing) as a daily production-scheduling tool. A large number of end products (around 300), sporadic demand, and limited shelf life of coffee (90 days) make it difficult to generate feasible production schedules manually. To solve this problem an integrated system was developed incorporating discrete event simulation methodology into scheduling process. The integrated system is comprised of two components: a scheduling program and a simulation model. The scheduling program is used to generate daily schedules for roasting, grinding, and packing coffee. The simulation model uses the generated schedules to simulate the production of coffee and regenerates a modified production schedule. In this paper, each of the components will be described in detail, evaluated in terms of performance factors, and validated with a set of real production data. Although this article focuses on a specific system, we will share our experiences and intuitions gained and encourage other process industries to develop simulation-based scheduling tools.

In this study, recycled aggregates crushed from waste concrete were sorted into three groups, 10-13 mm, 13-20 mm, and 20-25 mm. They were treated in different ways and then their crushability was evaluated for each treatment. Coffee waste was used for reducing their pH level. The pH of recycled aggregate was almost 11, regardless of aggregate sizes. The pH of coffee waste was nearly 5 and 10, 30, or 50 g of coffee waste was mixed with 1000 ml of distilled water and recycled aggregates. The lowest pH was about 6.2 when 50 g of coffee waste was mixed. Aggregates were treated with microwave or soaked for 1 day in vinegar (pH = 2) for neutralization reaction. Microwave treated and neutralized aggregates showed 3.3% and 6.2% higher crushing values compared to non-treated one, respectively. Neutralized treatment was more effective for crushing. In crushing tests, a sample height of 120 mm was tried, which gave 6.3% higher crushing value. A four stepped loading with each 100 kN gave 7.1% higher crushing value, compared to standard 100 mm height and 400 kN continuous loading.
