introduction
Coffee bean roasting loss is caffee, which refers to the phenomenon that the weight of coffee beans decreases due to the volatilization of moisture and other components during the roasting process. This loss is inevitable for coffee producers, but some strategies can be used to reduce the loss rate. This article will explore the best strategies to reduce coffee bean roasting loss.
Understanding the baking process
Before exploring the best strategy, we need to understand the roasting process of coffee beans. Roasting is the process of heating the raw beans to a certain temperature and for a certain period of time to achieve a specific flavor and aroma. During this process, moisture and other components will gradually evaporate.
Influencing factors
There are many factors that affect the roasting loss rate of coffee beans. The first is the original moisture content. Before being processed after picking, the green beans usually contain a higher proportion of moisture. In addition, environmental humidity, processing methods, storage conditions, etc. will also affect roasting loss.
Best Strategy
To reduce your coffee bean roasting loss rate, here are some best practices:
1. Café English controls the original moisture content
After picking, coffee beans need to be processed to remove the pulp and inner membrane. The original moisture content can be adjusted by controlling the time of washing, fermentation and drying. Higher initial moisture content will result in greater volatile losses.
2. Precisely control baking temperature and time
Different coffee varieties and flavors require different roasting temperatures and times. Precise control of these two factors can reduce unnecessary volatilization and keep the internal structure of the beans stable.
3. Optimize storage conditions
Storage conditions are crucial to keeping coffee beans fresh. Humidity, temperature, oxygen exposure, etc. can accelerate the evaporation process. Using airtight packaging and placing it in a cool and dry place can slow down the evaporation rate.
4. Choose the right processing method
Different processing methods will affect the roasting loss of coffee beans. For example, the natural drying method contains more water than the water washing method, so there will be greater volatile losses during the roasting process.
in conclusion
By exploring the best strategies to reduce coffee bean roasting losses, we can help coffee producers reduce costs and improve product quality. Controlling the original moisture content, precisely controlling the roasting temperature and time, optimizing storage conditions, and choosing the right processing methods are all key steps to effectively reduce the loss rate.
