Two key themes were once again in evidence on our pages this week: the importance of securing the supply chain in a world where commodities are becoming more hotly contested and the task of leveraging areas of growth in developed and developing markets.

Following rumours that chocolate giant Ferrero had made further strides in its endeavour to sure-up hazelnut supply, just-food was able to confirm that the group is "in discussions" over the potential acquisition of Turkish firm Oltan Gida.

The difficulties of expanding in mature markets were highlighted by our in-depth look at the challenges online retailing presents to food manufacturers and an analysis of Unilever's sale of Slim.Fast - a big fish in the shrinking pond that is diet foods.

While expanding in mature markets is a demanding task, this is not to say growing in emerging market is a cake-walk - as recent developments in Russia and India highlight. Nevertheless, food majors continued to push on in growth markets - from Fonterra's tie up with Abbott in China to a detailed evaluation of why food giants are lining up to invest in Egypt. Here are the highlights on just-food:
