We can take a step back to look at water activity and overall shelf life from a wider perspective. We use a few labeling systems in our longitudinal data set. One of those is for the round in which a coffee is cupped, an... Tag: 커피 이야기, coffee #커피 #water #물 #스페셜티 #specialty

Origins The basic observed relationship between score and Aw is slightly negative, as is that between score change and Aw. Neither is strong. Whilewe do observe lower volatilit with lower Aw coffees, it is important to g... Tag: 커피 이야기, coffee #커피 #water #물 #스페셜티 #specialty

We can also look at how water activity itself behaves over time. Here we see that there is a tendency for coffees to condense between around 0.525 and 0.5, given enough time. This specific range is likely a function of o... Tag: 커피 이야기, coffee #커피 #water #물 #스페셜티 #specialty

천안에 방문할 일 있어 검색 해보다 리무소 커피를 발견하였다. 직장 다닐땐 천안 출장이 종종 있어서 가긴 했지만 카페를 잘 가본 적이 없었다. 이유는 어떤 직장인이든 저녁에 역시 그 지역에서 술 한잔 하는게 아닌가 ㅋㅋ 어쨌든 매장 오픈 시간이 오전 12... Tag: 커피 이야기, 리무소 #커피 #에티오피아# 코스타리타 #게이샤 #

Lipid oxidation is important in green coffee because the oxidation of lipids can produce off flavors. A common compound in this category is called Trans-2-nonenal (T2N). T2N is produced by the autoxidation of linoleic ac... Tag: 커피 이야기, coffee #커피 #water #물 #스페셜티 #specialty

Finally, we come to the real question that we set out to answer way back when we started measuring water activity. Does Aw reasonably predict shelf life (storage and shipment stability)? This question itself is poorly fr... Tag: 커피 이야기, coffee #커피 #water #물 #스페셜티 #specialty

Looking at just the score change from PSS to ARR, coffees beginning above 0.610 drop an average of 1.53 points with a standard deviation of change (a of △) of 2.26 compared to 0.96 and 1.89 for those beginning below 0.5... Tag: 커피 이야기, coffee #커피 #water #물 #스페셜티 #specialty

Samples and Handling The samples used in this study come from 44 countries and include most commonly practiced processing techniques. We omit both Monsooned and decaffeinated coffees, as well as Robusta. Samples are deli... Tag: 커피 이야기

Given some background in water activity theory and specialty coffee, we can begin building a model for their interaction. One way to look at a large amount of data is to create a histogram. The one above divides nearly 2... Tag: 커피 이야기, coffee #커피 #water #물 #스페셜티 #specialty

Moisture Content: the amount of water in a system. Water Activity: the energy status of the water in a system. A coffee bean with some given moisture content can have a range of water activities. A coffee bean with some ... Tag: 커피 이야기, coffee #커피 #water #물 #스페셜티 #specialty

If we cut off coffee purchases at 12% moisture, we will cut off many Aw-related problems. The model gives an error of about 1 percent. If we pull the criterion back to 11% the problem region for Aw in specialty green cof... Tag: 커피 이야기, coffee #커피 #water #물 #스페셜티 #specialty

It is easy to see the term "browning reactions" and assume that this is in reference to what's occurring in the coffee roaster. The Maillard reaction, for example, is a type of nonenzymatic browning reaction that occurs ... Tag: 커피 이야기, specialtycoffee #browning #greencoffee #water

We set up two trials, as well as analyzed our cumulative dataset to further investigate the role of Aw in the roasting process of specialty green coffee. In one trial we took samples of various coffees from the roaster a... Tag: 커피 이야기, coffee #커피 #water #물 #스페셜티 #specialty

To further test the impact of Aw on roasting coffee we set up a small trial in which we altered the Aw of a single coffee in various ways. Methods and Materials In this trial we used four conditions: Control, Bath, Heat,... Tag: 커피 이야기, coffee #커피 #water #물 #스페셜티 #specialty
