Head Lettuce

Head Lettuce is one of the leafy vegetables and is also known as green salad.  The Greeks and Romans appreciated this salad due to the slightly calming effect of the white milky sap in its leaves. 

Besides green, there are also red lettuces. The red colour depends on the variety.  When there is a particularly intense colour, it is also a sign that the salad was exposed to strong light over a long period. Red coloration is caused by anthocyanin.  Anthocyanin-rich lettuces have tenderer and finer leaves than green varieties. There is also a difference between head lettuces raised outdoors or in greenhouses. Greenhouse head lettuce is usually larger and weighs considerably more. Furthermore, lack of light in winter prevents typical lettuce head formation inside greenhouses. This is why this type of salad is not suitable for long storage. Since lettuce is very sensitive to ethylene, store it separately from fruit.
