Inflation rose to 4.45 per cent for the week ended on July 28 from 4.36 per cent for the previous week as essential food items as well as some manufactured products turned dearer.
The wholesale prices-based index stood at 4.72 per cent during the corresponding week previous year.
Food items like fruits and vegetables, mutton, eggs, masur and bajra moved up.
Food products in the manufactured category like coffee powder, baby food, sooji, maida and flour also turned expensive.
However, prices of some metal alloys, tobacco products, beer, sunflower and raw cotton declined.
This is the second official wholesale prices-based inflation data after the Reserve Bank tightened monetary policy to suck out Rs 16,000 crore liquidity from the system.
Data on inflation presented mixed scenario after RBI's quarterly monetary review as it had fallen in the previous week.
However, the exact effect of the monetary policy could be gauged by the data to be released next week. Data pertaining to particular week is released after 15 days.
