Allow Me to Break the Ice – A Brief Introduction to Food Cold Chain Management

Cold chain management is gaining plenty of attention in recent months due to the specific storage and handling requirements of the COVID19-vaccines. Similarly, food cold chain management is a highly interesting field with multiple possibilities to improve operations.

First of all, one has to note that there are multiple variants of cold chain management concepts. Varying temperature ranges exists based on product requirements ranging from ultra-cold to ambient conditions. Perishable food is predominantly either stored and transported at frozen or chilled temperature ranges.

In this universe, there’s only one absolute… everything freezes!

Mr. Freeze

While the desired temperature range often can be controlled during storage and transport, loading and unloading activities are more complex. Particularly, in difficult delivery settings such as hot climate or urban settings where parking spaces are sparse, the time required to unload products can results in substantial quality impacts. This does not only affect the products which are currently unloaded, but potentially all other products on board a vehicle.

As a result, planning and decision-making tools for fresh and frozen food deliveries need to consider a wide variety of influencing factors to guarantee both food safety and quality during logistics processes. In literature, a wide variety of methods exists ranging from modelling these aspects through soft or hard time windows to implementing advanced food quality models and cross-perishability effects.

A promissing research direction to further improve cold chain management is the integration of techniques from data science and analytics. Sensor data from time temperature indicators or smart labels may allow one to predict potential problems in the cold chain early. This allows decision makers to react swiftly to related events, enabling one to reduce food waste, extend shelf life and deliver products with higher quality to the customers.

Consequently, food cold chain management offers a wide range of interesting research directions and various opportunities for businesses to improve operations. If done well, food waste and energy consumption is reduced and we all can enjoy a nice cold ice cream on a hot day.
