Parts of celebrity chef Maggie Beer's business empire including book royalties, television appearance fees and her own Farm Shop retail outlet will be off limits to investors in the partial float of the Maggie Beer Products premium food business on the ASX.

The range of activities being quarantined under a 48 per cent buyout of the Maggie Beer Products premium food business by ASX-listed Primary Opinions has been clearly outlined in a prospectus ahead of a vote on June 24 by shareholders in the Victorian acquirer, which is switching to food manufacturing and away from operating a legal services networking hub.
