Technology in Food Production

Over the coming weeks I am going to write a series of posts about technology and food production. Food is a topic that I have been interested in from a sociological perspective for several years, and I have a few topics that I would like to address, from GM, to regulation, sustainability and organic alternatives.

Technology plays a huge part in food production. If we just think about GM products, transport issues, industrial farming techniques and globalization in generic terms, it becomes immediately apparent that this sector is the largest in the world. According to these statistics agriculture accounts for between 14 and 24% of all global emissions of CO2, and 19 to 29% of total greenhouse pollutant emissions. An interesting point here is that in the so-called developed countries post-farm emissions are very high, so in the UK for example 50% of these emissions are produced after the food has left the farm, presumably through processing and transport techniques.

But it seems to me that processing is where the money is. According to Forbes, Pepsi for example made almost $45 billion in 2009 and Nestle’ made $110 billion, and these profits only refer to US sales. This year the sector is one of the very few that is still growing.

If you look at vegetables though they make less money. Dole is the largest producer of fruits and vegetables in the world, but in the same year made only $6.8 billion, leading me to conclude that the profit is in the processing and not in the actual foodstuffs themselves.

And this leads on to the question of what goes into these products. The answer is, largely, genetically modified (GM) organisms.

Genetic Modification

Genetic Modification

Yes if we look at the statistics that the US Department of Agriculture publish, we find the following:

93% of soybeans grown in the USA are GM

90% of all corn produced in the US is GM

95% of US sugar beat is GM

40% of all cropland in the US is used for Monsanto (the largest GM seed producer) production

40% of all global GM crops are produced in the US

35% of all the corn grown in the world is GM

81% of all the soybeans grown in the world are GM

I take some of my information from here, the Organic Consumers Association website and the rest from US government sources.

So as you can see it is big business. It is estimated that 70% of all the foods in our supermarkets contains GM organisms. 16.5 million people work in the industry in the US and it accounts for more than 10% of GDP.

And it is not just plants, there is a request for FDA approval for GM salmon. It grows at twice the speed of regular salmon.

The GM salmon, produced by AquaBounty Technologies contains a gene from a Chinook salmon that produces a growth hormone, and a genetic “on-switch” from an ocean pout (an eel-like fish) that keeps the growth hormone pumping out year round. The company state that GM salmon will consume 25 percent less feed, half of which can be plant protein.

Oh and in the US none of this is labeled, although currently 64 other countries do require labeling.

GM organisms have been found in many countries that do not allow their production however, Mexico comes to mind as the closest example to the USA. Seeds have blown across the borders from the US, over the mountains, across the seas, possibly even from Brazil and Argentina and landed and grown. Not to mention imports of contaminated produce. Read the scientific report here.

Corn is socially extremely important in Mexico, its cultivation all started there, and this contamination has caused some serious soul searching. In a related issue GM companies are currently trying to get permission for huge plantations in Mexico, as this Reuters article explains. We await the court’s decision.

For now I stop here, I think that is enough food for thought for this week (groan). Next week I shall delve once more into the murky waters of the global food industry however, and who knows what we might find. Comments please below.

Barcoding – a history and the future

Many youngsters these days are not aware of how recent barcoding technology actually is. In the 1970’s a mere forty odd years ago, it would have been a rarity to see a barcode – anywhere.

Before the barcode, retail was not nearly as efficient as it currently is. Often, till assistants would have to memorise the price of every product in the shop, or products would be individually priced. Furthermore, it was almost impossible to keep tabs on stock levels in real time.

Barcodes revolutionised industry.

Barcoding in retail

Now when you pick an item and take it to the till, a barcode is scanned. The till is linked to a central database where all the barcodes for that shop (or even the entire shop chain) are stored. Information on the price of the product, the stock of the product and usually a description and or image of the product, is all stored in relation to the barcode. Upon scanning, the price is retrieved from the database and one unit is deducted form the shops stock list.

Barcoding makes it easy to increase prices and to reorder stock, that way if something has high demand and is selling fast, more orders can (sometimes electronically) placed and the store can consider raising the price.

Barcoding in car production

Barcodes are also used in many other areas, one example being car production. In car production, each car will be given a barcode. That barcode will often contain information such as the type of car that is to be made, how the car is to be styled, what colour the car is to be pained etc.

Parts that have been made for that car will often also be associated with the same barcode, to ensure that every bit gets to the right car.

The classic barcode is the one with lots of vertical lines, each of different thickness. Below is an example of a classic barcode.

A Random Classic BarcodeDespite the classic barcodes uses, many people believe that the future of barcoding lies with QR codes.

QR Codes

QR codes are like barcodes in that they are all unique, however the image itself can actually store some information. QR codes are common in Japan, however they are slowly making their way westward, and and not uncommon in Europe now.

If you go to your fridge or a cupboard and pick up half a dozen items, the chances are at least one of them will have a QR code. I found one on some cheese the other day 🙂

QR Code‘ stands for ‘Quick Response Code‘ as they can quickly retrieve information, just by decoding the pixels in the QR code/image.

QR Codes are basically a code (durr) containing some form of information, be it text, a URL, etc. When you run the image through a QR decoder, it will work out what data is stored in the image.

Confused? Okay, let me give you an example. Below is a QR code image. If run the image through a smart phone QR decoder or an online QR decoder, you should find that it contains the information ‘www.TechnologyBloggers.org’. Why not try it out?

Technology Bloggers QR Code

When decoded this QR Code says 'www.TechnologyBloggers.org'


That information is stored in the actual image, and there is no need for you to connect to a database. That is why many people believe that they are the future of barcoding, as a barcode stores no actual data in the lines, just a reference to a counterpart on a database.

QR codes could store the name of a product and the price on that actual barcode image – although to deduct stock, they would need to be linked into the stock database.

In many countries, QR codes are being used in advertisements, and in some places, that are being used as the actual advert. This is to try and encourage people to decode the image and find out what it means.

So what do you think, are QR codes the future of barcoding? Could they both coexist, or will one emerge on top? What is your opinion of QR codes?

Over to you 🙂
