Bamboo Charcoal & Pyroligneous Acid
With the health trend booming, people are taking notice of “charcoal,” including bamboo charcoal and oak charcoal.
Bamboo charcoal in particular is gaining attention, as it has a quick growth rate and is kind to the environment, making it an eco-friendly product.
However, some are also questioning the quality and safety of even domestic products that may have been produced using Chinese bamboo with unknown origin or with unknown manufacturing processes using cheap imported bamboo.
At Takesumi no Sato, we’ve worked hard since it was first established to continue using persistent ingredients, fuel, and manufacturing methods without compromising the quality of the bamboo charcoal or pyroligneous acid.
Bamboo is purchased from local farmers who harvest bamboo from natural growing bamboo forests.
From a bamboo forest grown only for making original bamboo charcoal, Moso bamboo at least 4 years of age is used as our chosen ingredient. This preserves the quality required in increasing the value.
These are good quality bamboo that include plenty of minerals in its thick layers.
After the bamboo from the bamboo forest is cut and nodes are removed, it is left to dry naturally for over 3 months before undergoing a smoking process for 1 week.
By carefully smoking the bamboo, the moisture is trapped inside, which allows it to become a hard charcoal when it is burned.
Earthen furnaces are very delicate and difficult to control the temperature, but produce high quality bamboo charcoal, making it the best manufacturing method.
The burning temperature is over 800℃, so bamboo charcoal food products can be created without any tar included.
To fuel the fire, only natural firewood and bamboo are used. No gas, oils, or other chemicals are used in the process.
With consideration towards the global environment, the firewood is unused wood collected from local lumbermills.
We do not use wood coated with insect repellent or other chemicals.
To produce high quality bamboo charcoal, the carbonization temperature is very important.
Bamboo charcoal burned at a high temperature will be very hard.
It takes 10 to 14 days to heat up the inside of the kiln, then another 2 weeks to cool it down to air temperature.
The efforts of this month-long process results to our high-quality bamboo charcoal.
Quality and Safety
The powderization and inspection process are contracted out to ISO and Organic JAS certified companies to maintain proper quality control of the bamboo powder.
In addition, joint projects with Miyazaki University and The Miyazaki Prefecture Industrial Technology Center have provided analysis of bamboo charcoal and pyroligneous acid, as well as accumulated various data about the safe use. This research is used to help the farmers of Miyazaki, an agriculture and livestock prefecture, that use bamboo charcoal in their feed or fertilizer.
Also, guidance from the Miyazaki Industrial Support Foundation was received regarding proper quality control systems, as well as safety and hygiene management.
