The need to maintain the correct environment for food and medicine

Food grade warehouses serve as an invaluable link in the food supply chain. Between the fields of the farmer, the processor, the retailer, and finally the consumer. Specialized food storage facilities must undergo rigorous evaluation and adhere to precise guidelines. In addition, when food is also stored in restaurants and our homes, monitoring and controlling correct environmental conditions not only maintains the “Use-By” dates but provides confidence spoilt food does not affect our health. When selecting “Food Storage” from the user app, The Butterfly is automatically set up to notify you when the correct environmental conditions are out of the limit -providing comprehensive protection for food storage. 


Types of food-grade warehouses

There are several types of food-grade warehouses. Some of the most common include:


Cold or frozen storage – Storage at a minimum of 0° F (-17°C)

Chilled or refrigerated storage – Storage between 34° to 39°F (1-3°C)

Dry storage – Storage between 50° and 70° F (10-20°C)


The Butterfly's wide temperature range and industrial sensors satisfies environmental monitoring in all these ranges


Monitor 24/7, Notify and record historical data

Humidity, light, air quality, and dew points all also need to be controlled. For example, Humidity affects food storage negatively if the humidity levels are too high. Dry food that is exposed to moisture can grow bacteria and molds, spoiling food and causing illness. Moisture (Dew Point) also contributes to the disintegration of paper packaging, as well as causing rust on metal containers.


High temperatures and humidity can accelerate the spoilage of food products. Humidity levels in dry storage areas should not exceed 50% Relative Humidity (RH).


Food storage facilities are required to have health plans. The Butterfly in conjunction with ConsciousPro, not only time tags all measurements but also provides audit reports, notifications, and alarms, ensuring plans are well monitored. Even when there is a power outage, the Butterfly continues operating.


Light is the least understood enemy of food storage. Exposure to light can cause foods to spoil faster. Both natural and artificial light can cause photodegradation, according to the Department of Food Science and Human Nutrition at Clemson University. Exposure to sunlight, fluorescent light, or incandescent light can cause photodegradation. Dry food should never be stored in direct sunlight.


Sunlight degrades both the nutritional value and quality of food. This is especially the case for dry food items that are high in fat-soluble vitamins.


For home applications, like pantries or cupboards used for storing dry food, it's critical to monitor the environment. Food life cycle dates (“use-by”) are considerably reduced if the correct environmental conditions are not maintained. According to the Food and Drug Administration (FDA), proper home

food storage helps maintain safety as well as food quality by keeping flavor, color, texture, and nutrients in food. The Butterfly default settings are set up for proper dry food storage, and a guideline for how best to store different types of foods can be found at
