Oily mesocarp

Peculiarities of TAG Biosynthesis in Plants with Oily Mesocarp... 

At the same time, as it was mentioned above, there are some plants (oil palm, avocado, olive, sea buckthorn, durian, and others), in which a significant amount of oil is contained not only in the seeds, but also in the juicy non-seed parts of the fruit arillus, pericarp, hypantium, mesocarp, etc., TAG of which are not used by the plant itself as a source of organic matter and energy. Such plants are called as plants with oily mesocarp (POM). With regard to TAG composition, these juicy non-seed parts of many POM fruits contains highly saturated oil with predominance of Cie FAs, palmitic and hexadecenoic (or Ci8 i FAs, as a rule, oleic but in some cases noticeable concentrations of its positional isomer, c 5-vaccenic acid, also occur) [42-46, 79], while the seeds of the same fruits accumulate TAG rich in polyunsaturated Cis FAs, linoleic and a-linolenic [42, 80]. 

Palm oil is the pulp oil extracted promptly after harvesting from the fleshy mesocarp of the oil palm fruit using continuous screw presses. The liquid coming from the press is a mixture of oil, water and non-oily solids (NOS). After separation from sludge in a setthng tank, clarification, purification and vacuum drying, crude pahn oil (CPO) is yielded from the press liquid.
