Do raw coffee beans need to be washed?
Do raw coffee beans really need to be washed?
Good coffee beans are bagged and transported everywhere, this method may not be very clean, and even some monks have water or mud stains on the surface.
If you carefully examine the microbes on the surface of raw beans that are invisible to the naked eye, you will find that there are about 10,000 bacteria on every gram of raw coffee beans.
However, this does not mean that raw coffee beans must be washed, because after baking, most of the dust will fall off, and the high temperature during baking can kill almost all microbes.
On the contrary, the washed raw coffee beans have two points to pay attention to. First, be careful not to soak for too long. If you soak in water for too long, many ingredients that make up the flavor of coffee will be lost; second, pay attention to moderate drying. If the drying time is too long, it is easy to breed mold. If the drying time is too short, there will be uneven drying, resulting in uneven baking. If cleaning is necessary, then I suggest washing quickly, drying moderately, and then using up the raw beans as soon as possible.
On the other hand, I have a paradoxical idea that those who sell coffee will realize that raw coffee beans are not clean. Why would you think that? Because the hygienic requirements of raw coffee beans, the sacks that pack them and roasted coffee beans are not the same. Placing roasted coffee beans next to the sacks of raw coffee beans or leaving the sacks of raw coffee beans open are common phenomena in family bakeries. Although you don't need to make the coffee beans as clean and beautiful as the exhibits, you should at least know that it is not hygienic.
In the industry, few people can treat coffee as "food"-what kind of food industry will grab what guests import with their hands? Would put food and unsanitary things together? This is a problem of consciousness, which will bring harm to everyone. The dust on raw beans or gunny bags can easily induce allergies and cause erythema on people with allergic constitution. Therefore, I think that in order to make consumers feel at ease to eat coffee, every coffee practitioner should raise the hygiene awareness of coffee beans.
