Information on Frozen Food

A Brief History of Frozen Food

Frozen food has been around since 3,000BC, when the ancient Chinese started using ice cellars to preserve food through the cold winter months and beyond. The Romans also used to store provisions in compressed snow in insulated cellars. So, at least in principle, frozen food has been with us for a long time!

The modern frozen food industry, however, only dates back to the early 20th century when Clarence Birdseye - fur trading in Labrador, Canada in 1917 - observed how local inhabitants preserved fresh fish and meat by letting it freeze rapidly in the cold Arctic temperatures. He also discovered fish left over from a previous expedition that had been preserved by the intense cold. The locals had discovered that freezing made it possible to preserve products at the very peak of quality, while at the same time locking in all their freshness and taste.

Birdseye brought the idea back to the United States where he spent years perfecting the process we now know as quick freezing. Quick freezing is a technique where each individual food item or small groups of produce is rapidly frozen at extremely cold temperatures in order to obtain small ice crystals so that the food cells are not damaged. The rest, as they say, is history...

Facts on Frozen Food/Food Safety

Storing, defrosting and cooking frozen foods safely
Freezing is an excellent means of preserving food. This section will provide you with an introduction to on how to get the most from your frozen foods through proper storage and defrosting. For more detailed information see how to get the best from frozen food

How does freezing preserve foods?
• It's impossible for bacteria to multiply on frozen food - which makes it safer than any other form of food preservation.
• Many foods today are 'quick frozen'. This is a process, which freezes the water in the food into smaller ice crystals, minimizing cell structure damage. Quick-freezing foods and then storing them at temperatures -18°C or lower slows the natural degradation process practically to zero.
• So, make sure you store your frozen food correctly, and it will retain its colour, texture, nutritional value and taste.

Storing frozen foods
• All foods can be safely frozen, but some foods should not be frozen for quality reasons.
• Food stored consistently at -18°C or lower will remain safe indefinitely.
• Most domestic freezers should operate at temperatures -18°C or lower. As a general rule, if your freezer can't keep an ice cream block solid, its temperature is above the recommended level.
• Always refer to the on-pack 'best before' date. The manufacturer's 'best before' date is a quality indicator and is the date until which the product will remain of peak quality (when stored at -18°C or below). For storage in a 3-star or 4-star freezer manufacturers will normally recommend 'store until best before date'.
• After the 'best before' date a reduction in eating quality may become evident, whilst the product remains safe to eat.
• Try to rotate foods; putting newly purchased items at the back of the freezer so older items are used first.
• Freeze your food in appropriate containers, for example, freezer bags and airtight containers.
• Most foods obey the rule 'the colder the better'. Domestic freezers have a star rating indicating the temperature they are designed to operate at.

On the packaging of a frozen food item there is often guidance stating how long the food can be stored using freezers of a given star rating. As a list guide here are some suggested MAXIMUM storage times of frozen foods at -18°C.

The Pressing Problem of Waste

How frozen food can help
There's no doubt that food waste is a hot topic in the UK at present. At the same time, we're living through the most serious economic crisis of recent times. Both issues have an obvious link to thrifty and responsible housekeeping.

Some startling facts...
WRAP (Waste and Resources Action Plan) is a government agency dedicated to understanding the population's patterns for disposing of waste and evaluating the benefits of recycling. They've recently published some startling and persuasive facts:

• In the UK, we throw away around one third of the food we buy.
• Of that 61% or 4.1 million tonnes of food waste a year was avoidable.
• The most common reason for food being wasted is that it's left unused - 61% of the avoidable food waste or 2.5 million tonnes.
• Of this, 40% - almost one million tonnes - isn't even touched and at least a tenth - 340,000 tonnes - is still in date.
• We also cook and prepare too much, resulting in an additional 1.6 million tonnes of food waste a year.
• UK households on average pay for £420 of food every year that could have been eaten but instead is thrown away.
• Every tonne of food waste is responsible for 4.5 tonnes of CO2.
• Between us we throw away around 6.7 million tonnes of food every year - roughly one third of all the food we buy. Most of that food (61%) could have been eaten if we had planned, stored and managed it better.
• In the UK we thrown away 1,405,000 tonnes of fruit, vegetables and salad.

Some useful tips...
Here are some tips on how you can make a difference.

• Keep your grocery shop regular (eg. once a fortnight) and buy in bulk
Frozen food can help here. Buy perishables daily but only to supplement the core meals that come from frozen. Cook two or three extra portions of any one recipe at the beginning of the period and then immediately freeze the extras.
• Plan your meals in advance
Sticking to a plan stops you coming home from the supermarket with a load of food, but no real idea of what you are going to cook. Planning won't just cut back on waste - it will save you a lot of time and money as well!
• Plan your shopping list
Having planned your meals, this is the next logical step. Make a list and stick to it! The facts above are telling in this respect - 340,000 tonnes of food every year that is completely edible, yet never makes its final destination.
By planning in advance what you're going to eat, you can buy frozen food and know what it is that you're going to cook three or four days away. Contrary to popular belief, there's a huge range of frozen foods that cover nearly every food range. The chances of getting bored with the same thing are pretty low!
• Use and understand your freezer

You really can buy almost anything in frozen form - from herbs through to meat, bread through to cakes or fish. Correct care and maintaining your freezer will become your most useful tool in the fight against waste.

• Make sure you get your portion control correct
By only cooking what you need straight from the freezer, you will get your portion control more accurate. Also, remember that world food prices are going up. The more we waste, the faster they will rise. So work out what you eat in terms of weight, and make a note for future reference. Eventually it will become second nature!

• Use your leftovers - don't throw them away
The freezer and Tupperware are the two best things that ever happened to waste management. Make the most of both of them, and you'll always have a freezer full of frozen uncooked food and frozen leftovers ready for reheating!

• Don't shop hungry
Feeling hungry will tempt you into buying a whole load of stuff you don't really need or want! By shopping soon after you've eaten, you will become a lot more discerning with your grocery shop.

• Think of ways to cut down on packaging
It's not just food that we waste... the packaging it comes in is now also proving to be a massive burden. Major supermarkets have recently been told by the government that they must look at ways to reduce packaging. By thinking green and considering the frozen alternatives, you will naturally reduce the amount of packaging waste that you generate.

Frozen food makes it easy
In most cases, cutting back on waste isn't much more than common sense! It certainly needn't take up too much time or effort. Just apply some of the basic rules above, and make sure that you plan ahead when you're shopping for food. You'll make a difference in the long run and you'll start saving yourself money straightaway!

Frozen food - whether you buy it frozen, fresh or chilled - will help you here. Not only can its quality and convenience make shopping, and cooking, a whole lot easier, it will also help you cut down on a lot of the unnecessary wastage that our modern lives generate.

Top Environmental Aspects of Frozen Foods

Reduces food wastage
Frozen food helps reduce food wastage, as you only take out what you need and save the rest for another day! UK consumers throw away about 1/3 of the food they buy, so there is great scope for improvement. WRAP states that if people stopped wasting food which could have been eaten, it would have the same impact on carbon emissions as taking 1 in 5 cars off UK roads.

http://www.lovefoodhatewaste.com/about_food_waste

Reduces individual carbon footprint
By buying frozen food with its longer shelf life you could make fewer trips to the supermarket by car. Doing so would reduce your individual carbon footprint.

Energy savings
Your freezer uses less energy if it is kept stocked up. Also by placing the freezer as far away from the cooker/fridge as possible will help to make it run more optimally, as keeping it close increases energy usage. It is even better to have a separate chest freezer in the garage or a separate room. For more information on understanding your freezer click here.

All nature’s crops can be harvested and used
In times of abundant supply freezing crop, such as peas, can ensure the entire crop is available for sale. Sometimes excess fresh cops need to be ploughed back into the field or left to rot simply because of its short life.

Sustainability
The vast majority of frozen seafood companies use sustainable fisheries to source their products; by buying frozen you contribute to making seafood more sustainable.

Due to its longer shelf life, frozen food potentially requires fewer deliveries to supermarkets; hence frozen food may have fewer trucks on UK roads.

Why buy frozen fish?

Fish and seafood begins to decline in quality immediately after catching, so freezing as soon as possible retains quality and seals in freshness.
