Right, you had a question. The estate of Astrid Lindgren has registered the "Pippi Longstocking" trademark in the U.S. for audio-visual goods and printed matter as well as for games, educational services, and for clothing. A year before the latter registration issued, the trademarks for Pippi Wear (t-shirts) and Pippi Tails (hair bows) were registered by a California enterprise that doesn't appear to have any official connection with the Swedish author (yet conjures up the Pippi character in their advertising -- P.S. Beware the Cyndi Lauper audio).
Pippi and food trademarks.Ennyway, we're not sure what's up with all that and we're hesitant to presume anything about the various uses. Most importantly, there is no indication that either the Swedish trademark owners or the California owners are planning to expand into food products and as far as we can tell, nobody is using Pippi as a federally registered trademark for food products. Therefore, we don't see any reason why you shouldn't proceed with the registration (though there is no such thing as a "guaranteed" registration). And yes, you are wise to avoid any references to the literary character in your advertising and packaging.
