This article on fruit juice, only a few pages long, gives a bit on history of the market segment and the technology that went with it, something on health benefits, the current world situation and trends. After that is of course the bit that says how much GEA can help juice manufacturers.

Having linked to their separator, decanter and process based information, I also saw they have general information like that above and of course process information linked to other Unit Operations – so there will probably be more!

Although the article does not mention newer technologies such as radiation and pressure processing and does not expand on the science of preservation, knowing the history helps to give a wider view when one considers preservation.

The author ends by saying “Interests have shifted from preserve “because we have to”, to “preserve because we like to.”. This of course applies to the modern richer urban dweller and not poor rural communities.

Its interesting to think that if urban people still had preservation capacity the Local Food movement would be much more successful!

This is in the form of an interactive graphic presentation in which you choose your wheat variety and watch it being “planted and growing”. After the wheat has grown (the stage where I am now) you have to wait for an email to enter the next stage.

Not really a good idea if you don’t have band width and not really high tech but you always learn a bit! Lets see what the next stages offer.
You are probably better of visiting the wheat page on Wikipedia if you want quick but quite extensive background.
