A student project showcased at California State University San Marcos alleged the programme unfairly portrayed villainous character as members of racial minorities.
Eric Metaxas, who also narrates the show, told PJ Media: "All vegetables are part of one race, even though they are of many colours.
"They are all descended from the same parents - the Adam and Eve of vegetables, who foolishly ate a forbidden fruit (irony?) and screwed everything up for all vegetables descended from them
"At least, I'm pretty sure that's the story."
According to student news website College Fix, the project, named 'Children in the Church', claimed bad characters in VeggieTales tend to have accents of ethnic minorities, such as Latinos.
It concluded: "When kids see the good white character triumph over the bad person of colour character, they are taught that white is right and minorities are the source of evil."

The display formed part of a 'Whiteness Forum' which critically analysed the portrayal of race in the media and public life.
Other exhibits criticised racial representation in the National Football League (NFL) and support among white women for Donald Trump.
