【Invisible Risk】Causes and Countermeasures for Ochratoxin A, a Mold Toxin Lurking in Coffee

Thank you for your continued support.
This is Gokujo Mold-Free Coffee.

Coffee is something we consume casually every day. However, behind the scenes, there's a substance that food safety agencies worldwide are wary of: mycotoxins (mold toxins), especially "Ochratoxin A," which is prone to occurring in coffee beans.

This time, we will explain why mold toxins remain in coffee, the process by which this risk arises, and the thorough measures we take.


1. What are Mycotoxins (Mold Toxins)?

Mycotoxins are harmful metabolic substances produced when certain types of mold proliferate. Among them, "Ochratoxin A," which is a problem in coffee beans, is a very stable substance and is said to be difficult to eliminate completely even with roasting heat.

Effects on the Body

Ochratoxin A is known to pose risks such as kidney toxicity and carcinogenicity with long-term intake. While it doesn't cause a sudden decline in health, continuous "accumulation" can be a factor in damaging health, so caution is necessary.

2. Why do Mold Toxins Remain? (Timing of Occurrence)

The main reasons for mold toxins in coffee beans are "improper processing" and "improper storage."

① Problems during the processing stage

When harvested coffee cherries are dried, mold can rapidly proliferate if they get wet from rain or are placed directly on damp ground. Especially in regions where drying takes a long time or on farms with inadequate management, the risk of contamination increases at this stage.

② Humidity during storage and transportation

Coffee beans are transported by ship for a long time from the producing region to Japan. If humidity is not properly managed during this transportation or in warehouses upon arrival, even once-dried beans can reabsorb moisture, and mold can become active again.

3. Our Commitment to "Gokujo Mold-Free Coffee" to Prevent Mold Toxin Residue

We are implementing the following initiatives to thoroughly eliminate the risk of mold toxins from every cup that reaches our customers.

  • Selection of Clean Processed Beans: We only handle beans from trusted farms where humidity is low and processing management is thorough.

  • Thorough Temperature and Humidity Control: We store beans in an environment that preserves their freshness and prevents mold growth.

  • Third-Party Inspection: We don't just rely on "no visible mold"; we conduct scientific tests (mycotoxin tests) and deliver only beans that have been proven safe.


Summary: Choosing Safe Coffee Builds the Foundation for Health

To fully enjoy the wonderful flavor and health benefits of coffee, it is crucial to eliminate the risk of invisible "mold toxins."

If you want to experience the inherent power of coffee, such as "relieving fatigue" and "improving concentration," please choose tested, clean beans.
