| Abstract | The valorisation of Reutealis trisperma seed for the production of non-edible oil and protein was investigated. Reutealis trisperma fruits contain approximately 60-61 wt%, d.b. mesocarp, 26-28 wt%, d.b. endosperm and 13 wt%, d.b. endocarp. The endosperm of ripe Reutealis trisperma fruit contains about 54-59 wt%, d.b. non-edible oil whereas the mesocarp contains only 3-9 wt%, d.b. oil. The cake obtained after the extraction of oil from the endosperm was mixed with the endocarp (20 wt% cake and 80 wt% endocarp) and used as feed (50 mg/larva/d) for the cultivation of Hermetia illucens larvae in a rearing container. The feed contains 39.2 wt%, d.b. hemicellulose, 10.9 wt%, d.b. cellulose and 29.9 wt%, d.b. lignin and 0.2 wt%, d.b. ash. The protein content of the feed was 19.1 wt%, d.b. A prepupal dry weight of approximately 50 mg/larvae was obtained after 12 d of treatment with an estimated productivity of 10.2 kgprepupae/m 3 container.d. The estimated efficiency of black solider fly larvae in converting digested food was 21.6% with an assimilation efficiency of 27.7%. The prepupae of Hermetia illucens contains approximately 37.6 wt%, d.b. protein and 33.2 wt%, d.b. fat. As such indicates that the remaining biomass from Reutealis trisperma seed after the oil extraction has the potential to be used as feed for the production of protein-rich biomass. |
