CO₂, humidity, and temperature management are critical for preserving potatoes in cold storage. IoT monitoring systems optimize conditions to:
Ensure potato quality and freshness with IoT-driven storage management for optimal CO₂ and temperature control.
Have you ever wondered how potatoes stay fresh for months in cold storage without spoiling? It might surprise you, but the secret lies not just in cold temperatures — CO₂ gas, humidity, and temperature control all play big roles in keeping potatoes in perfect condition.
In this blog, we’ll break it down in simple terms, but also include just the right amount of technical detail so you understand what’s really happening inside those giant cold storages.
After harvesting, potatoes are still alive and need to be stored carefully. Without proper storage, they will:
To prevent this, they are stored in cold storages — large rooms or warehouses with tightly controlled temperature, humidity, and air quality.
Now here’s where it gets interesting…
Even after being harvested, potatoes are still alive. They continue to “breathe” — not like humans, but through a process called respiration. In this process, potatoes take in oxygen (O₂) and release carbon dioxide (CO₂).
Simple version of potato respiration:
Glucose (from the potato) + Oxygen → Carbon Dioxide + Water + Energy
Over time, CO₂ gas starts building up in the storage room — just like how a room can get stuffy if it’s closed for too long.
There are several ways storage operators control the gas levels:
Imagine cold storage like a cozy bedroom for potatoes:
If any one of these isn’t managed properly, your potatoes are going to feel the stress — and it’ll show in their quality, which will impact business and revenue.
| Parameter | Ideal Range | Why It Matters |
| Temperature | 4°C – 10°C | Slows sprouting and microbial activity |
| Humidity | 90% – 95% | Prevents shrinkage and keeps potatoes firm |
| CO₂ Level | Less than 1–2% | Reduces sprouting but avoids internal damage |
| Oxygen Level | Around 20% (normal air) | Needed for safe potato respiration |
Storing potatoes is part science, part care. Cold storages are not just “fridges” — they’re controlled environments that work round-the-clock to maintain the right balance of temperature, humidity, and air gases like CO₂. The better these are controlled, the fresher your potatoes stay.
So next time you enjoy crispy fries or a hot potato curry, remember — there’s a bit of hidden science behind every bite!
