A peer-reviewed study published in Sustainable Microbiology (Oxford University Press) has identified specific environmental conditions — measurable in real time — that precede fungal contamination in manufacturing and storage environments, offering a scientific basis for shifting mold management from reactive inspection to proactive prediction.
The research, conducted by YCM Mold Research Center (YCM Products Co., Ltd., Changhua, Taiwan), examined how combinations of humidity, temperature, carbon dioxide (CO₂), and particulate matter (PM10) interact to create conditions favorable to mold growth on products and manufacturing surfaces. The findings earned Best Presenter Awards at two international conferences: ICEI 2025 in Tokyo and ICBSTS 2025 in Nagoya.
The Problem: Inspection Catches Mold Too Late
Across industries from footwear and textiles to cosmetics and food-contact goods, current mold management practice depends on visual inspection — a method that only identifies contamination after it has already developed.
This creates a structural vulnerability that inspection alone cannot close: products that pass factory checks before shipment can still develop mold in transit, when sealed packaging traps humidity and reactivates residual spores that were below detection thresholds at the time of inspection. The consequences — recalls, reputational damage, financial loss — are disproportionate to the contamination event that triggered them.
What the Research Found
The YCM study moves the conversation from “how do we inspect for mold” to “what conditions make mold inevitable.” By identifying the environmental parameters that consistently precede contamination events, the research establishes a measurable, data-driven basis for early intervention.
Humidity, temperature, CO₂ levels, and PM10 particulate concentration were identified as the key variables. Their interaction — not any single factor in isolation — determines whether conditions cross into mold-risk territory. Monitoring any one parameter alone provides incomplete protection.
“Manufacturers cannot manage a risk they cannot see. Our research changes that. Environmental conditions are now measurable, trackable, and predictable well before contamination becomes visible, and that changes what manufacturers can reasonably be expected to prevent.”
David Chen, CEO, YCM Products Co., Ltd.
Why This Matters Beyond Regulated Industries
Environmental monitoring for microbial risk is already standard practice in pharmaceutical and sterile manufacturing, where regulatory frameworks mandate it. What this research highlights is that the underlying science applies equally to consumer goods sectors — footwear, apparel, logistics, toys, furniture — that operate without such mandates and have historically relied on passive protection methods.
Conventional tools such as essential oil treatments and humidity-control stickers function as last-line defenses, addressing moisture after contamination risk has already begun to accumulate. Continuous environmental monitoring operates upstream — identifying threshold conditions before product exposure becomes a contamination event.
From Research to Practice
YCM has applied these findings to SpaceAIoT, a field-deployable sensor system that tracks humidity, temperature, CO₂, and PM10 across production floors, warehouses, and shipping environments in real time, converting raw environmental data into continuous mold risk intelligence.

Frequently Asked Questions
The research identifies humidity, temperature, CO₂, and PM10 particulate matter as the key environmental parameters that interact to create conditions preceding fungal contamination in manufacturing and storage environments.
The findings are relevant to footwear, textiles, apparel, toys, furniture, cosmetics, food-contact goods, and pharmaceuticals — particularly manufacturers and logistics providers operating in tropical regions or high-humidity supply chains.
SpaceAIoT is YCM’s field-deployable environmental monitoring system that tracks humidity, temperature, CO₂, and PM10 in real time, converting them into continuous mold risk intelligence across production, storage, and shipping environments.
Traditional methods such as essential oil treatments and humidity-control stickers address moisture after contamination risk has already developed. Continuous environmental monitoring identifies risk thresholds before contamination begins, enabling preventive intervention rather than remediation.
