The increasing demand for biofuel, which is derived from biomass — usually plants — has taken a bite out of supplies of crops and other farm products worldwide. The redirection of crops from mouths to fuel tanks is reflected in the rise of prices of ordinary food items in Japan.
For the first time in 17 years, Q.P. Corp., Japan's biggest mayonnaise maker, will raise the price of its main product by about 10 percent, starting with Friday's shipment.
"It's because the price of the ingredients, mainly rapeseed and soybeans, rose," said Shunsuke Horiike, spokesman for Q.P., citing stronger demand in China. But he also blamed the price hike on biomass fuel.
