Vice: Should You Keep Ketchup in the Fridge or Not?
Recently, a debate’s been going down online, with people divided over whether ketchup’s rightful home is in the fridge or the cupboard….
Dr. Rick Holley, a researcher studying the microbial ecology of food spoilage at the University of Manitoba, said you’d be fine if you eat ketchup stored at room temp, but voted for storing ketchup in the fridge. “From a food safety perspective, because ketchup has a low (<4.6) pH, it is acidic [and] does not need refrigeration to keep it safe,” Holley told MUNCHIES. “However, its colour is more stable at lower temperature in the dark (fridge is better).”
