Researchers from Cornell University think that it is because spice plants have some important chemicals（化学物质）．These chemicals can kill bacteria（细菌）which spoil food．
"Most common spices can kill 75to 100percent of the bacteria in food，"explains one of the scientists．The bacteria grow more easily and spoil food more quickly at higher temperatures．For this reason，it is more difficult to keep food from spoiling in hot climates，
