"I've had over 40 pizzas in the last 30 days, and it's not the same pizza," Schnatter told WDRB. "It's not the same product. It just doesn't taste as good."
The company's slogan is "Better ingredients. Better pizza."
Schnatter, resigned as chairman in 2018 after admitting to using a racial slur during a company conference call about diversity training.
He had stepped down as CEO in 2017 amid controversial comments he made regarding NFL players kneeling in protest to social injustices.
Schnatter told WDRB he used a racial epithet to make a point about racism.
"This is all a farce. Nothing sells like the truth, and the truth, sooner or later, all comes out," Schnatter told WDRB. "Stay tuned. The day of reckoning will come. The record will be straight."
