Following General Mills acquisition of macaroni and cheese maker Annie's for over $800 million, or more than four times revenue, expect a smorgasboard of deals in the natural and organic space. Not only will food giants be looking to buy growth by picking up companies in the fast growing segment, but private equity firms are also seeking to invest. Among publicly traded companies, industry sources have cited WhiteWave,, parent of brands such as Silk almond milk and Horizon organic milk, as the most attractive target despite its own hefty valuation. A number of privately held companies have popped up on the auction block, with a deal announcement expected within the next few weeks for Mankato, Minn.-based kettle corn maker Angie's Boomchickapop. Other candidates up for grabs are Dallas-based Talenti Gelato and Bellvue, Colo.-based Noosa Yoghurt.
