Superior, incompletely five-celled, stigma sessile; staminal bundles reduced to allabnlackia few free, ca. After decolonization in Africa, the research efforts to discover new, alternative oilseeds continued. Flowering occurs during a large part of the year, in particular from January to September.
Only comments or links that are felt to be directly relevant to a plant will be included. The oil yield obtained from solvent extraction was higher than from the manual expression Allanblackia floribunda Home x 89 – 6k – png spellwell.

In addition, the demand for oils and fats from alternative plant sources has floribunea increased, driven by several factors including: Leaves opposite, simple and entire; stipules absent; petiole c.
The FAO had already identified Allanblackia as a crop of high potential interest indue to the potential for the seed oil which was listed as a non-edible oil at that time to become a profitable and sustainable raw material, the development of which could benefit rural communities [ 29 ].
For oil extraction, the seeds are dried well before they are taken to the buying centres, where trained personnel check the moisture content and weight, after which the seeds are ready for storage in gunny bags.
Fat high in stearic acid favorably affects blood lipids and factor VII coagulant activity in comparison with fats high in palmitic acid or high myristic and lauric acids. Although no phytochemical investigations of A.
The male flowers of A. The Scramble for Africa. To extract the seeds, fruits are crushed between florbiunda hands and seeds are rubbed clean. The quality parameters, namely the acid index, iodine index, and refractive index values, were similar for these two oils, although the former two parameters were higher for A.
Allanblackia Oil: Phytochemistry and Use as a Functional Food
The fruits are eaten by wild pigs and porcupines, which may distribute the seeds. Only when oil derived from the correct plant species floribundx plant part unadulterated is used can the product be deemed safe for human consumption and assessed as to whether it has the chemical constituency that it claims.

Triglyceride components consisted mostly of 2-oleostearin The seeds contain a fat that is solid at ambient temperatures. Selection criteria include seed and fruit size and abundance, and tree size and structure. In addition, more recent studies on seed germination and propagation, sex determination of individuals, population biology, and genetic diversity for selected species in specific geographic locations have been carried out [ alllanblackia34 ].
Allanblackia comprises about 10 species, and is restricted to tropical Africa. In Nigeria it is used in construction of local houses. The wood is locally used, but is of secondary importance. Growth and development Under natural conditions, trees start flowering after about 12 years.
