Understanding the impact of temperature on perishable goods

Temperature has a significant impact on perishable goods. Different products have varying temperature requirements to maintain their quality and freshness. For example, fruits and vegetables are best stored at slightly above freezing temperatures, while frozen foods require much colder temperatures to remain frozen.

Exposure to higher temperatures can accelerate the growth of microorganisms, causing spoilage and reducing shelf life. On the other hand, extremely low temperatures can lead to product damage, affecting texture, taste, and overall quality. Striking the right balance is crucial to ensure that perishables remain fresh and safe for consumption.

The difference between -15°C and -18°C for transporting perishables

When it comes to transporting perishables, the choice between -15°C and -18°C depends on the specific requirements of the goods being transported. While both temperatures fall within the sub-zero range, there are slight differences in their effects on perishables.

-15°C is commonly used for perishable goods that require a consistent cold chain, but not necessarily freezing temperatures. This temperature range helps to slow down the growth of bacteria and microorganisms, preserving the freshness and nutritional value of the products. It is often used for transporting fresh produce, dairy products, and certain pharmaceuticals.

On the other hand, -18°C is typically used for goods that require freezing temperatures to remain in optimal condition. This temperature range ensures that the products are kept frozen throughout the transportation process, maintaining their texture, taste, and quality. It is often used for transporting frozen foods, ice cream, and certain medical supplies that need to be kept at ultra-low temperatures.
