How Independent Lab Science Validates the Efficiency of BEfresh®
Fresh produce spoilage is largely driven by ethylene gas—a natural plant hormone that accelerates ripening, softening, and decay. At BEfresh Solutions, our products are designed to tackle this problem at its source by removing ethylene from the environment, helping fruits and vegetables stay fresh longer.
To validate the science behind ethylene‑removal technology, BEfresh commissioned an independent laboratory study conducted by Cambridge Refrigeration Technology (CRT) in the United Kingdom. While the study evaluated a pellet‑based ethylene filter, the results directly support the same core technology and chemical mechanism used in BEfresh sachets and solutions today.
This blog explains how the study connects to BEfresh products—and why it matters for real‑world freshness.
The CRT study specifically tested potassium permanganate (KMnO₄)–based ethylene‑absorbing material, the same proven chemistry that underpins BEfresh technology.

What the Independent Study Tested
CRT evaluated three critical performance factors that directly relate to BEfresh product efficiency:
- Ethylene adsorption capacity – how much ethylene the material can remove
- Material durability – whether the active material holds up under pressure
- Moisture and packaging performance – how the system performs in humid environments
These factors mirror the real‑world conditions BEfresh products are designed for: refrigeration, produce storage, and daily handling.
Ethylene Adsorption: Proof of Effectiveness
In the study, ethylene‑absorbing material was placed in sealed chambers with a known amount of ethylene gas. After exposure, CRT measured how much ethylene remained using a gas chromatograph.
The results showed an average ethylene adsorption capacity of 4.94 liters per kilogram of material.

How this relates to BEfresh
This measurement confirms that ethylene‑absorbing materials actively and measurably remove ethylene gas—the exact function BEfresh sachets perform inside produce drawers, storage bins, and packaging.
In simple terms: if ethylene is removed, ripening slows. This scientific result supports BEfresh’s real‑world benefits of extended shelf life, reduced spoilage, and less food waste.
Durability Matters: Material Strength Testing
CRT also tested the crush strength of the ethylene‑absorbing material to understand how it performs under physical stress. The material demonstrated an average crush strength of 5.64 kg, indicating strong resistance to breakage.

Why this matters for BEfresh users
BEfresh products are used in environments where movement, stacking, and handling are unavoidable. Durable ethylene‑absorbing materials ensure:
- Consistent performance over time
- No breakdown during normal use
- Reliable freshness protection throughout the product’s lifespan
Moisture Resistance: Performance in Real Conditions
Produce storage environments are naturally humid. To simulate this, CRT conducted a drip test, exposing the product to controlled water flow and measuring how long it took for moisture to pass through the packaging.
The test showed that moisture took over 14 minutes to pass through the system.

What this means for BEfresh
This test validates an important principle behind BEfresh product design: ethylene‑absorbing solutions must work effectively without leaking or failing in humid conditions.
For consumers, this means confidence that BEfresh products are:
- Safe to use around fresh produce
- Designed for refrigerator and cold‑chain environments
-
Built to protect both food quality and storage spaces
What the Results Mean for BEfresh Efficiency
Although the CRT study evaluated a pellet‑based format, the science, chemistry, and performance metrics directly apply to BEfresh products. The study confirms that:
- Ethylene‑absorbing materials measurably remove ethylene gas
- Durable materials maintain effectiveness during use
- Proper packaging design supports performance in humid environments
Together, these findings reinforce why BEfresh products consistently help produce last longer, look better, and taste fresher.
Science‑Backed Freshness You Can Trust
At BEfresh Solutions, reducing food waste starts with proven science. Independent laboratory validation gives our customers, partners, and retailers confidence that BEfresh technology is built on real data—not just claims.
By addressing ethylene at the source, BEfresh helps households and businesses get more time, more value, and less waste from fresh produce.
