The decision to increase prices, by five percent, for the first time in nearly a year is significant in a country where most food is flash or deep fried -- and will increase pressure on the already stretched budgets of the poor.
Singapore-based Wilmar International, a major edible oil supplier in China, has been permitted to raise the prices of its products by around five percent starting from August, the company said in a statement.
The rise, approved by China's powerful economic planner National Development and Reform Commission (NDRC), was the first increase since October 2010, it said.
No one at the NDRC was immediately available to comment when contacted by AFP.
Chinese business magazine Caijing said state-owned food conglomerate COFCO also received "tacit consent" to raise prices to cover soybean costs which have been rising since last year.
State media reported in December that the NDRC had asked several major edible oil companies, including Wilmar International and COFCO, to refrain from raising prices in an effort to rein in inflation -- a key bugbear for Beijing.
Authorities have been intervening directly in the commodity market, warning a number of companies not to increase prices as they crack down on hoarding and offer subsidies to the poor.
In May, the NDRC fined consumer products giant Unilever for "illegally disseminated news of price hikes" that sparked panic-buying of shampoo and detergents, but it later decided not to punish the firm, state media said.
Food prices have soared this year after severe summer floods destroyed crops in regions previously affected by drought while a shortage of pigs has driven up the cost of pork, a staple meat in the Chinese diet.
In June, the country's consumer price index (CPI) rose 6.4 percent -- the highest level in three years -- further fuelling concerns among policymakers about inflation's potential to trigger social unrest.
Prices of food, which constitutes around one-third of CPI, were up 14.4 percent from a year earlier, partially driven by a 57.1 percent jump in prices of pork.
China is scheduled to release consumer inflation data for July early next week.
