Every story from the desk: supply, processing, retail and the people who make the food industry run.
Most temperature excursions are not dramatic truck failures. They are short, repeated warm spells at handover points: docks, cross-docks, back rooms and store floors.
CO2, ammonia and propane are moving from niche to normal as high-GWP HFCs are phased down. Each suits different sites, and each brings its own safety and skills questions.
From single-use USB loggers to cellular trackers and warehouse sensor networks, the options for monitoring temperature have multiplied. Here is how to choose.
Both move heat out of food fast, but they serve different purposes. Choosing the right one, and sizing it properly, decides safety, texture and throughput.
RTD coffee, tea, protein drinks and cocktails all compete for the same chilled cooler doors. Refrigerated space is the scarcest and most expensive real estate in a store.
Individually quick frozen (IQF) processing keeps pieces separate and quality high. Newer freezer designs, sensors and packaging are pushing the technology further.
Refrigeration runs around the clock in a commercial kitchen. Small maintenance habits and targeted upgrades can cut energy use without risking food safety.
Fresh produce keeps breathing after harvest. Modified atmosphere packs, ethylene absorbers, antimicrobial films and freshness indicators all aim to slow that clock, but only inside a working cold chain.
Ready-to-eat foods are very popular, and the equipment that makes them is changing. Gentler processing puts more weight on chilling, hygiene and temperature control.
Online grocery has moved the end of the cold chain from the store to the doorstep. Totes, insulated liners, multi-temperature vans and delivery windows are the new control points.
Single-serve coffee kept growing after the forecasts of the early 2020s. The harder questions now are about packaging recovery, freshness and the energy cost of a cup.
Oat, soy, almond and pea drinks, yoghurts and cheeses each bring different processing problems: emulsions, heat treatment, fermentation and chilled shelf life.
Sprinkles, nonpareils, sugar pearls and decorations ride the gifting calendar. Their quality problems are mostly about humidity, heat and colour stability.
Hemp grown for CBD leaves behind large volumes of plant material. Researchers have studied whether it can safely feed livestock, and the answer depends on residues, regulation and storage.
Sugar beet seed is a high-tech, tightly controlled input. Disease, pesticide rules and post-harvest beet storage now shape demand more than acreage alone.
When a cannabis company signed with the largest US beverage alcohol distributor, it signalled how hemp and CBD products might reach mainstream shelves. Here is what such deals involve, and why logistics matter.
Peelable lids, tear notches, clamshells and resealable trays make food easier to open. The design choices also decide how well a pack survives the cold chain and how it is recycled.
The dietary supplements industry is booming on health awareness. The less visible story is how heat, humidity and handling affect potency, and which products need cold storage.
Vanilla is in ice cream, drinks, bakery and confectionery. Its supply is concentrated, labour-intensive and weather-exposed, and its value depends on careful curing and storage.
Frozen dough and par-baked products depend on additives that protect yeast, gluten and crumb through freezing. Their performance is only as good as the cold chain they travel in.
Global demand for nutrition-rich snacks keeps fruit snacks growing. Making fruit portable means controlling water, sugar and texture, and some formats need the cold chain.
Soy lecithin is one of the most common emulsifiers in food. Its grades, non-GM sourcing, allergen labelling and storage behaviour all affect how manufacturers use it.
Construction firms such as RK built suicide prevention policies after losing a colleague. Food processing and cold-store operations share many of the same risk factors, and many of the same fixes.
