New lettuce discolours less rapidly | 12 Oct

Rijk Zwaan introduces a trait in its lettuce varieties that ensures that the leaves discolour pink less rapidly after cutting. The vegetable breeding company has nick-named the trait ‘KNOX’. Jan Doldersum, Manager Marketing & Business Development will tell the story of the new trait at Food Valley Expo.

KNOX extends shelf-life by about two days. Rijk Zwaan directly responds to one of the main wishes of fresh cut companies with this development. KNOX ensures you do not necessarily need low-oxygen packaging for lettuce; this allows for lower costs and more options when blending. This means getting rid of the negative smell that is characteristic of opening low-oxygen packaging.

Less waste
KNOX is also beneficial for the rest of the chain. For example, the extended shelf life gives retailers a better stock position and less waste. It is self-evident that these benefits will also lead to a better end consumer experience. The consumer can enjoy the bag of pre-packaged salad for a longer time. It is expected that KNOX will lead to higher purchasing frequency, and therefore increased consumption of lettuce.

Rijk Zwaan worked on the development of KNOX for a total of 10 years. The worldwide market leader in lettuce developed an assessment test in house in order to determine the presence of the trait, and then found it in a breeding greenhouse. The unique effect was confirmed in various laboratory tests and large scale factory trials. The property was subsequently crossed into various lettuce types as soon as possible.
