Handle products with multiple origins for ingredients and places of transformation
The origin: I would add some button with an "extended info" label on it to show fields to enter the origin of the ingredients and the manufacturer and/or packer separately. Nowdays, we have many products with a spanish (in my case) brand and company, but with the main product(s) coming from China, Perú, Brasil... the results of the Globalization. So, many people that look for consuming more local products and reduce the ecological footprint would like to know ingredient's origin and manufacturer/packer origin. Also, in most Fair Trade products, you have a very detailled info about the origin of the different ingredients like sugar, cocoa or coffee, and it would be nice if we can included in the product information. Probably the better way to include all of this is have a table (like in the nutritional section) to include Ingredient 1, Ingredient 2, Manufacturer, Packer and so on. (suggestion by Javichu)

This is a very interesting suggestion. One one hand I’m trying to keep the product form as simple as possible, so that products can be added as quickly and effortlessly as possible. And on the other hand, more information is better.
Maybe we could try to offer an alternate representation of the list of ingredients, in a table as you suggest. The table view would be constructed from the plain text data, and contributors could add extra information like origin, whether the ingredient is organic, from fair trade etc. or not.
It’s not as easy as it sounds though, as sometimes the ingredients list contain sub-ingredients etc. so the table might not always work.
