the world of frozen foods

what is commercial frozen food?

Commercial frozen food refers to food products processed, packaged, and frozen on an industrial scale to extend shelf life, typically stored at or below 0 degrees. It includes ready-to-eat meals, pizzas, vegetables, fruits, and snacks. These items are preserved by freezing to stop microbial growth without requiring added preservatives.

Key Details About Commercial Frozen Food:

Categories: The market includes frozen entrees, vegetables, fruits, desserts, ice cream, seafood, meat, and baked goods.

Processing: Manufacturers use advanced technology like flash freezing (cryogenic) to maintain quality and texture by creating smaller ice crystals.

Storage & Sale: These products are transported and sold through cold chain logistics to supermarkets, convenience stores, and restaurants.

Popularity: Driven by convenience, these products meet the demand for quick meals and are increasingly offering gourmet or healthy options.

Market Size: The industry is massive, with global sales for frozen foods exceeding billions of dollars, driven by urban lifestyles and demand for long-lasting food.

a brief history of frozen foods

Frozen Food: The Beginning

In colder climates, freezing for preservation has been around for as long as animals have been hunted and food has been gathered. In any area that had sub-zero temperatures for even part of the year, freezing would have been used. Where temperatures were just above freezing, storage times could be prolonged and populations made use of natural caves and cool streams for this purpose.

In fact, evidence of man-made ice houses – used for refrigeration rather than freezing - in more temperate areas have been dated as early as 1780 BC, though they didn’t become popular in the UK until 1950, over 3700 years later!

First Steps

The first commercial freezing operation in the world was founded in 1861 at Darling Harbour in Sydney, Australia. This freezing works became the New South Wales Fresh Food and Ice Company and trialled shipments of frozen meat to London by 1868.

However, the venture was not a success, thanks in part to the slow freezing process, meaning the frozen food was largely tasteless and leaked a large amount of water when defrosted.

Clarence Birdseye: The Captain of Cold

From 1912 to 1926, Clarence Birdseye worked alongside the Inuit in Newfoundland, Canada, as a fur trapper. During this time, Birdseye noticed something that would revolutionize the world of frozen food and give rise to a modern industry expected to be worth $156.4 billion by 2020.

The fish caught by the Inuit fishermen would freeze almost immediately when pulled from the water in the sub-zero winter conditions. Birdseye noted that the fish retained its flavour and texture, even when it was defrosted months later.

Fast-forward to 1920 and Birdseye is experimenting with frozen peas. He found that by blanching peas immediately after picking and then fast-freezing them resulted in a frozen pea which was eye-catchingly green.

So it was that in 1929 Birdseye introduced his 'fast freezing techniques' to the American consumer and the frozen food industry was born.

1940-60s: The ready-meal revolution

During the 1940s, the volume of frozen foods available to consumers boomed. It wasn’t until the 1950s, though, that the first frozen ready meals hit the shelves in the United States.

By the 1960s, so-called convenience food was all the rage and frozen ready meals mirrored the changes taking place in society, as more and more women left the traditional housewife role and moved in to the workplace.

1970-80s: Home freezing and improved choice

In the 1970s, home freezers became far more affordable and widespread as a result. This gave rise to improved choice in frozen foods (with oven chips and pizza hitting the market). What’s more, people could now enjoy a greater range of frozen desserts, with families no longer restricted to ice cream.

1990s and beyond

With frozen foods now a regular part of almost every family’s weekly diet, the focus shifted to the nutrition of frozen food.

Since quality., nutrition and taste became the watch-words of the frozen food industry we’ve learned a lot about making really good food.

how commercial frozen foods are made

Key Steps in Production

Preparation & Pre-treatment: Ingredients are washed, peeled, cut, and often blanched (briefly boiled) to deactivate enzymes that cause spoilage.
Cooking (For Ready Meals): Meals are prepared, sometimes fully cooked, and assembled in trays. A common method involves filling trays while hot, then cooling, which helps control bacteria like Listeria.
Rapid Freezing Methods:
- Blast Freezing: Ultra-cooled air (down to or colder) is blown over food on conveyors.
- IQF (Individually Quick Frozen): Small items like berries or peas are frozen individually, preventing clumping.
- Cryogenic Freezing: Food passes through tunnels cooled by liquid nitrogen to freezing the surface instantly.
Packaging: Frozen food is sealed in airtight, moisture-proof materials to prevent dehydration and freezer burn.
Storage: The product is stored in freezers at consistently low temperatures to maintain safety and quality throughout the cold chain.

Common Techniques by Food Type

Vegetables: Usually washed, blanched, and then quickly frozen via IQF to retain crispness.

Frozen Meals: Ingredients are mixed, assembled into trays, and often blast-frozen.

Fried Foods (e.g., Fries): Potatoes are washed, cut, blanched, par-fried in oil, and then frozen.

in conclusion

Frozen dinners are pre-cooked, packaged meals designed for quick reheating, offering extreme convenience, portion control, and long-term storage. While historically high in sodium and preservatives, modern options include healthier, premium, and diverse global cuisines. Popular brands include Hungry-Man, Banquet, and new gourmet entries from celebrity chefs.

Frozen dinners, popularized by Swanson in 1953, revolutionized home dining with pre-portioned meals designed for easy, fast, and long-lasting consumption. Often high in sodium and fat, modern options offer varied nutritional quality. They are flash-frozen, locking in nutrients, making them a comparable option to home cooking in terms of nutrition, yet they frequently use preservatives to maintain stability.

While Swanson marketed the first "TV Dinner" in 1953, William L. Maxon developed the concept earlier in 1944 for air travel and the Navy.

Gerry Thomas, a salesman for Swanson, is credited with naming them "TV Dinners" because they were meant to be eaten while watching television. The original Swanson meal in 1953 consisted of turkey, cornbread dressing, gravy, peas, and sweet potatoes.
