MONTPELIER, Vt. — A new Log Cabin syrup looks like the real thing that’s made in Vermont, right down to its packaging in a plastic jug with an “all natural” label.

But Vermont officials argue that Log Cabin All Natural Syrup contains unnatural ingredients — including caramel color and xanthan (ZAN’-than) gum — plus a mere 4 percent maple.

They want the U.S. Food and Drug Administration to investigate whether Log Cabin Syrup, a division of Pinnacle Foods LLC, is violating FDA labeling laws.

Vermont Congressman Peter Welch says the syrup “dilutes the value of one of Vermont’s finest products.”

Pinnacle Foods spokeswoman Michelle Weese says the company believes the new syrup complies with all FDA regulations. The FDA says it doesn’t have a definition for “natural.”
