Walk a supermarket aisle today, and you’re witnessing a once-in-a-generation shift.
Major retailers are beginning to remove synthetic dyes and other additives from everyday foods, replacing them with simpler, natural ingredients.
The net effect could be significant: fresher, less shelf-stable products require more refrigeration at every step of the supply chain. Whether it is “Make America Healthy Again” or simply the convergence of policy and changing consumer demand, the push for fewer synthetics and more natural alternatives is reshaping how food is made, shipped, and stored.
To replace petroleum-derived dyes, food scientists are turning to botanicals and fruit and vegetable extracts. Natural color systems, often based on anthocyanins and other plant pigments, are top-of-mind in reformulation and, while innovation is improving shelf stability, these ingredients are more sensitive to heat, light and time than their synthetic predecessors. That sensitivity drives manufacturers to re-engineer handling processes, increasing the need for temperature-controlled environments.
When natural colors are incorporated into concentrates or blends, they tend to be handled chilled or frozen, thawed within strict temperature ranges, and kept cold after opening — all of which favors larger, denser refrigerated staging and storage in plants and distribution centers. A typical natural-color beverage concentrate from a global foodservice brand, for example, specifies thawing at 32–40°F and continuous refrigeration after opening.
Natural inputs, from fruit- and vegetable-based colors to enzyme systems and protein fortifiers, arrive as chilled or frozen concentrates handled cold after opening. This shifts plant-level and regional distribution center space from ambient to cold or controlled-cool environments, elevating demand for dock positions that maintain temperature integrity.
Natural systems can also be more sensitive to temperature, light and pH. In response, manufacturers are building in buffers for shelf life and transport conditions, further increasing reliance on cold storage for quality assurance across the network.
At the same time that natural food preferences are changing, pharmaceutical cold chain demand is on the rise. GLP-1 medications like Ozempic are experiencing phenomenal growth and are changing the healthcare logistics landscape due to their refrigeration requirements. GLP-1s and biologics require cold chain validation from fill-finish to last-mile. Distributors are expanding refrigerated square footage and automation—investments that bleed into markets such as New Jersey and Pennsylvania, which have deep pharma workforces and infrastructure. As a result, leading distributors are pouring capital into capacity to manage a pipeline where roughly half of new drugs will require some form of temperature control.
Pharmaceutical and food cold chains are expanding in parallel, and in some markets they are converging in mixed-use, cGMP-capable facilities.
Structural drivers intact
After a historic development burst over the past five years, U.S. cold storage vacancy ticked up to its highest level in two decades as speculative projects delivered into softer food inventories. This is a snapshot of the current environment, however. Underneath, the long-term structural drivers are intact. Online grocery adoption, menu and meal-kit growth, domestic food production upgrades — and now, policy-driven shifts — all funnel toward a bigger, smarter cold chain.
Nowhere is this clearer than in New Jersey and the Greater Philadelphia region, where the nation’s largest refrigerated port complex anchors a dense consumer base. On the ground, vacancy in true Class-A cold storage is basically near zero, even as some older space remains on the market.
South Jersey alone totals about 10.6 million square feet across 51 buildings, with only a handful of spaces available. New product is being developed in Northeast Philly and along the Delaware River, and a new cold facility is slated to deliver in 2027. This is a replacement-cycle story as much as a growth story, given the age of most cold storage stocks. The average U.S. cold building is roughly 40 years old, and refrigeration systems age out much faster than typical warehouses, according to a 2023 analysis by Newmark.
For developers, that means future-proofing by designing for precision and resilience. Cold storage isn’t a “dry box with chillers,” but rather multiple temperature zones, heavy power with redundancy, vapor-tight envelopes, insulated slabs to prevent frost heave, specialized racking, and life-safety systems, all married to tenant processes that can’t be interrupted by outages.
It also means planning for the realities of today’s ingredients and therapies: more perishables, more variability, stricter dwell-time standards, and pharma-grade handling, with a migration toward newer, better-specified assets built for both food and pharma.
Parts of the country are digesting space following aggressive construction over the past few years. But in the Northeast corridor, with close proximity to ports and population, cold storage buildings are getting leased, and the MAHA-era restructuring underway in America’s pantries is only going to deepen the need for controlled environments. In the Northeast and nationally, there is fundamental long-term strength. Policy, population, and pharma are combining to drive a new cold chain.
