Commercial and village processing

The commercial processing of fats and oil requires expensive and sophisticated equipment. At the village level, some of the basic steps in oil 

The literature contains only a few examples of the types of procedures used or required for oil processing of tropical fruits and fruit by-products. Moringa peregrina locally called Yassar in Saudi Arabia contains seeds that have been used as a source of oil. At the village level, the oil is extracted by boiling the seeds with water and collecting the oil from the surface. The extracted oil is called Al-Yassar (Somali et al., 1984). 

Okra seed can be ground in a home grinder and the ground seed can be sieved on a simple screen to partially separate the hull from the kernel. The resulting meal had about 33% protein and about the same percentage of oil. This okra seed meal can be used in baked products where it subtitutes for part of the flour and part of the oil. Pilot plant studies for the commercial processing of okra seed have also been investigated. 

Fairly efficient separation of the hard hull and the kernels was achieved with cracking rollers set to 0.38 mm followed by screening on 16-mesh sieves. Various low-boiling aliphatic hydrocarbons were found to be effective in solvent extraction. The flavors of both the deodorized and hydrogenated products were good. Hydraulic extraction of okra seeds produced a much darker oil than that produced by solvent extraction (Telek and Martin, 1981).
