Thank you for your continued support! This is our premium mold-free coffee.

The number of people choosing decaffeinated coffee (decaf) has significantly increased due to reasons such as "I want a coffee I can safely drink even at night" and "I want a body-friendly option with reduced caffeine stimulation."

However, among health-conscious individuals, the risk of "mycotoxins" in decaf beans is currently the most significant concern.

Based on objective data, we will explain the blind spots in the distribution unique to decaf beans, hidden behind the image that "it should be body-friendly because it doesn't contain caffeine," and the correct knowledge to prevent health problems.

Why are decaffeinated beans more prone to mold?

Behind the scenes of the coffee industry, decaffeinated green beans are known to be significantly more difficult to manage in terms of moisture than regular beans, making them the most mold-prone and high-risk beans.

The reason lies in the special process of "extracting and removing caffeine" from the raw beans before roasting.

In safe decaffeination methods currently in use (such as the water process), green beans are first soaked in a large amount of water to remove caffeine. At this stage, the beans absorb moisture to an extreme degree, so they must then be uniformly redried to their normal moisture content (around 10-12 percent) suitable for transport and storage.

This redrying process requires highly advanced technology and significant cost, so in the mass production market, drying tends to be insufficient, and it is not uncommon for beans to be shipped with residual internal moisture.

Vulnerability of Processed Green Coffee Beans Green beans subjected to caffeine extraction exhibit a characteristic of easily absorbing ambient moisture due to cell wall relaxation. It is pointed out that if strict temperature and humidity control is not maintained during distribution and storage, there is a risk of rapid proliferation of strains that produce mycotoxins such as Ochratoxin A. (From risk assessment data for imported foods by the European Food Safety Authority (EFSA))

Once decaf beans have absorbed moisture, they become more susceptible to absorbing humidity. Therefore, if condensation occurs inside containers during several months of ocean transport across the equator, they can become a hotbed for harmful mold far more easily than regular beans.

Further Blind Spots: Organic (Organically Grown) × Decaf

Many people choose "organic decaffeinated" for health reasons, but this presents an additional unique risk.

Organic green beans are strictly prohibited from using chemical preservatives or anti-mold agents (post-harvest pesticides) from cultivation to transportation and customs clearance. This means that "forcibly suppressing mold with chemicals" is not an option.

When these two conditions—decaf beans that easily absorb moisture and are prone to mold, and organic beans that cannot use preservatives—are combined, if temperature and humidity control throughout the entire distribution is not perfect, a large amount of mycotoxins can be produced at an invisible level.

Ironically, the phenomenon of organic decaf, chosen with the intention of being "body-friendly," ending up containing the most unnecessary toxins is occurring behind the scenes of today's mass production market.

"Sub-health (Minor Ailments)" Caused by Mycotoxins That Don't Disappear Even with Roasting

It is often thought that "mold and toxins will disappear if roasted at high temperatures," but this is a significant misconception.

About the Thermal Stability of Mycotoxins Mycotoxins commonly found in food, such as Ochratoxin A, are extremely heat-resistant. Global research reports that they are not completely destroyed even after the high-temperature roasting process exceeding 200 degrees Celsius and can remain in the final beverage. (From joint risk assessment data by the World Health Organization (WHO) and the European Food Safety Authority (EFSA))

Trace amounts of mycotoxins in decaf will not immediately cause severe acute poisoning. However, it is said that daily consumption can lead to the accumulation of unnecessary "noise" in the body, causing unexplained minor ailments (sub-health) such as "mental fogginess after drinking (brain fog)," "sharp stomach pain," and "body sluggishness."

In particular, individuals who consistently avoid "the four poisons (wheat, vegetable oils, dairy products, and sweets)" and follow a diet that thoroughly suppresses chronic inflammation in the body tend to be more sensitive to even slight toxins and impurities in food, as their bodies have returned to their naturally healthy state.

Summary: Choose by Thoroughly "Subtracting" Unnecessary Risks

Precisely because decaffeinated coffee is chosen to avoid caffeine stimulation and care for the body, it would be self-defeating if it contained the "noise" of mycotoxins that cause unnecessary inflammation in the body.

To choose truly safe and clean decaffeinated coffee, it is important not to judge merely by the image-based words "organic" or "decaf," but to ascertain whether substantial quality control, such as the following, is implemented:

• Is caffeine safely extracted using only natural mountain water, without any chemicals?

• Are defective beans, which pose a mold risk, thoroughly removed through hand-picking by skilled workers?

• Is "no mycotoxin detected" certified as scientific evidence by submitting each batch to public institutions, not just for differentiation?

The most crucial aspect of maintaining health in modern times is not adding good things to the body, but rather a "subtraction strategy" that thoroughly eliminates bad things.

Choose clean decaffeinated beans that are untainted by chemicals or mycotoxins. Experience for yourself a cup that truly cares for your mind and body, free from unnecessary risks.
