Mould Toxins Detected in 40% of Regular Coffee? MHLW Survey Data and an Unexpected Pitfall After Opening

I'm Kamei, the owner of Mold-Free Coffee.

1. Introduction

Shocking data, impossible for coffee lovers to overlook, has been revealed in a research report by the Ministry of Health, Labour and Welfare. Specifically, a certain mold toxin was detected in 40% of the regular coffee we drink daily.

On the other hand, if instant coffee, which showed 0% in the survey, seems safe, a unique risk is actually hidden "after opening." We will explain the reality of mold toxins and the knowledge needed to drink coffee safely to the very last drop.

2. The Reality of "Regular Coffee and Mold Toxins" Revealed by the Ministry of Health, Labour and Welfare Survey

In the 2020 "Survey on the Contamination Status of Mold Toxins (Health and Labour Sciences Research Grant)," commercially available coffee was also subjected to rigorous testing.

As a result, the following figures were shown for regular coffee:

Survey item: BEA (beauvericin = mycotoxin) mold toxin
Positive rate for regular coffee: 40.0%
Positive rate for instant coffee: 0%

The fact that mold toxins were detected in 4 out of 10 samples of regular coffee highlights the importance of quality control at the raw bean stage.

3. Caution! Instant Coffee is Dangerous "After Opening"

Although instant coffee showed a "0% positive rate" in the survey data, this refers only to "unopened products." In reality, instant coffee has a unique risk after opening.

Instant coffee is porous (has tiny holes) to make it easily soluble in water, and it is characterized by its high hygroscopicity.

Using a wet spoon
Forgetting to close the lid
Condensation due to temperature changes

If instant coffee absorbs moisture due to these factors, it can cause mold to grow inside the jar. Even if there are no mold toxins during manufacturing, there is a possibility of mold risk later depending on storage conditions at home.

4. "Coffee Selection and Storage Methods" to Minimize the Risk of Mold Toxins

To ensure the safety of the coffee you drink daily, keep the following points in mind:

Regular coffee: Purchase from a trustworthy shop that conducts mold toxin inspections and strict quality control at the raw bean stage.
Instant coffee: After opening, completely block out moisture and consume as quickly as possible. Be careful of condensation caused by taking it in and out of the refrigerator.

5. Conclusion

This official survey data highlighted the difficulty of quality control in regular coffee. At the same time, even with instant coffee, risks arise depending on how it's handled after opening.

Having the discernment to choose "mold-free coffee" and paying attention to storage after it reaches your hands. Both of these are essential for a healthy coffee life.

安心して飲める

バターコーヒーを12年飲んでいます。信頼できる知り合いのメーカーのコーヒーを飲んでいましたが、コーヒーの値段の高騰のため、購入をやめました。
極上カビなしコーヒーを高いけど、一度は飲んでみたいと飲みました。頭も体調、すこぶるいいです。トイレの回数も減りました。定期購入を自分へのプレゼント🎁しました。ありがとうございます。

体質じゃなかった!カビだった!

私は、これまでコーヒーを飲んだ後で起きる倦怠感と低血糖症状に悩まされていました。
何度もコーヒー断ちもしましたが、大好きなので出されると、つい飲んでしまい、また飲み始めたりを繰返し、最近は薄めにして回数や時間を調整しながらにしていました。過去には膵臓の精密検診もしましたが原因分からずで、私はコーヒーの合わない特別な体質なんだと諦めていました。ところが、カビ無しコーヒーを飲んでみると、低血糖症状出無くなり身体が軽い!ビックリです!今は普通の濃さで美味しいコーヒーを飲める幸せを味わっています♡

それからもう一つ、カビ無しコーヒーを飲み始めて、これまでコーヒーを飲んだ後に必ず起こっていたトイレに行きたいが無いのに驚きましたが、2ヶ月経った頃のこと、私は尿蛋白が検診の度に＋1か良くて±だったので、定期的に自分で試験紙を使って検診していましたが、なんと20年ぶりにマイナスになり、今もそれが続いています!ビックリです。私は看護師ですが、自分は将来的に膵臓か腎臓に関わる病気に可能性があると心配でしたので、食事には気を配ってきましたが、コーヒーを替えただけで、その両方の心配から一揆に解放された。身体の不調の原因が、まさかカビだったなんて⋯怖
カビで不調が現れる人、現れない人様々だし、現れたとしても症状は人それぞれでしょうが、健康を考えるならカビは避けるが良いでね。
素晴らしい商品です。出会えたことを心から感謝申し上げます♡これからもずっと定期購入続けます。

後味スッキリ！！

カビなしコーヒーを、SNSで初めて知り毎日飲んでるので興味があり注文してみました。
雑味がなく、とてもスッキリしていて飲みやすくて感動しました！！
また注文します。

柔らかい口当たり

カフェインレスはこれまで意識したことがなかったですが、飲むタイミングで寝られなくなることがあり今回購入してみました。
もっと物足りないかと思いましたが、カフェインが入っていなくてもコクがあり、満足できるお味でした。カフェインレスな分、口当たりがソフトに感じました。
これで夜中にコーヒーが飲みたくなっても安心です。
