Meet Open Heart Cos
In terms of popularity, cos lettuce is the fastest-growing lettuce variety worldwide. This type of lettuce, known in the USA and Australia as 'Romaine,' boasts several favourable traits, such as a crispy, sweet flavour and an appealing colour transition from yellow to green. However, cos lettuce is also susceptible to tip burn and tends to turn pink quickly after cutting. With Open Heart Cos, Rijk Zwaan offers a solution to these issues.
Discover the benefits of Open Heart Cos
Solid rib
No pinking through the rib = better looks and shelf life – better quality
Machine harvestable
The leaves of Open Heart Cos can easily be harvested mechanically
Open headed, healthy heads
Solid rib advantages
Open Heart Cos is specially developed for fresh-cut companies. The main rib is solid which eliminates pinking when it is cut. The vein is also thinner/ less prominent, meaning that it fits better on sandwiches, and large chunks of vein no longer make their way into bagged salads. Open Heart Cos – Specially for Fresh Cut
During growth, the heads stay open longer, making this specific cos lettuce, known as ‘Romaine’ in countries like the USA and Australia, less susceptible to tip burn on the inner leaves – hence the nickname Open Heart Cos. Furthermore, the openness of the head means that it easily separates into loose leaves after cutting, making it suitable for mechanical harvesting.
A single head yields numerous uniformly sized leaves with an attractive green colour. Over eighty percent of the leaves from each head are usable, which minimizes waste.
The leaves are precisely the right size and shape for fresh-cut companies: long and all the same narrow width, resulting in uniformly cut lettuce for the perfect Caesar salad.
