FRANKFURT, Jan 23 (Reuters) - The euro zone inflation rate, excluding volatile energy and food prices, does not gauge future price pressures well, European Central Bank President Jean-Claude Trichet was quoted as saying on Sunday.

In an interview with the Wall Street Journal, Trichet said that the greatest danger right now would be to stop the reform process that started during the financial crisis, and added austerity would strengthen, not kill the recovery process in the euro zone.

"In our case, we consider that core inflation is not necessarily a good predictor for future headline inflation," Trichet told the newspaper, and added the central bank is ensuring higher energy prices do not seep into other prices.

"That being said, all central banks, in periods like this where you have inflationary threats that are coming from commodities, have to go through the hump and be very careful that there are no second-round effects. This is what we are doing."

But he added that there are no signs of second-round effects on prices yet in the 17-country bloc.

"At this stage, we do not see this. And everybody knows we would not let second-round effects materialize," he said.

Headline inflation in the euro zone jumped to 2.2 percent in December, the first time in more than two years that it topped the ECB's target of below, but close to 2 percent.

However, core inflation has remained much lower at 1.1 percent in the same month and analysts expect it to rise slowly this year, indicating domestic price pressures in the euro zone are contained.

Some analysts have speculated that the ECB may look at core as much as headline inflation when setting monetary policy, speculation Trichet may have wanted to dispel.

Trichet also said euro zone policy interest rates, currently at a record-low level of 1.0 percent, are appropriate. The ECB kept rates on hold last week, but said the euro zone faces short-term price pressures -- taken by some in financial markets as a sign it could raise rates earlier than previously thought.
