Drying is one of the oldest ways to preserve food there is, going back thousands of years. It’s simple, safe and helps keep the colour, aroma and flavour of our ingredients for longer.
Not only does drying keep flavour locked in, it’s also a great alternative to using preservatives. Which makes a lot of sense – nothing is added when drying our vegetables and only the water is taken away.
The whole idea of drying a product is that you remove the water so you don’t need preservatives.
When harvesting tomatoes, Knorr farmers will let them go thirsty for a week or so first - this increases their sweetness and reduces the amount of water that needs to be taken out. We measure the sweetness of our tomatoes with something called a Brix test – and the higher the number, the sweeter they are.
