Detoxification of jatropha kernel meal to utilize it as aqua‐feed

Abstract: BACKGROUND Jatropha is an oilseed crop with high kernel oil (55–58%) and protein (26–29%) contents, which makes it a good source of biodiesel and animal/aqua‐feed. However, the presence of anti‐nutritional toxins, such as phorbol esters, lectins, trypsin inhibitor, phytate, and saponins, restricts its use as feed. This paper describes chemical, ultraviolet (UV) radiation, and biological treatments for detoxification of jatropha kernel meal. Raw, defatted, and one‐time and two‐times mechanically expressed oil s… Show more

“…From the presented results, it is also clear that phytic acid and saponins cannot be eliminated by heat treatments. Saponins are particularly heat-stable, and their biological activity cannot be diminished by typical cooking heat treatments [21,27,33]. The efficiency of heat treatments in the phorbol esters' concentrations (Table 1) is quite variable and most heat treatments show low levels of reduction on its concentrations, with studies demonstrating that roasting and other cooking treatments did not significantly affect phorbol esters' levels [19,20].…”

“…However, the second method does not apply to oilseeds with high oil content. When the oil extraction process is performed at a low temperature, the solvent extraction method has another advantage because it gives better quality of produced oil [ 6 ].…”

“…There are varieties of Jatropha curcas known by their origins, for instance from Nicaragua (Cape Verde and Nicaragua), Nigeria (Ife), and Mexico (Papantla) [ 5 ]. However, the different varieties contain different levels of bioactive compounds, as affected by both genotypes and geophysical conditions [ 6 ]. Makkar et al [ 5 ] categorized the Jatropha curcas plant as toxic and non-toxic genotypes, where the seeds of the toxic varieties contain phorbol esters, while the non-toxic varieties do not.…”
