“…In contrast, The USA Food and Drug Administration approved simmondin as safe for human use and animal feed [17]. From the bright side, [18] reported that elimination of anti-nutritional factors in jojoba seed meal could be done by different methods, including solvent extraction, heat, chemical treatment and microbial fermentation. Jojoba meal, as a by-product of jojoba seeds, is a promising feedstuff after being detoxified [19].…”

Abstract:The study aimed to investigate the effect of replacing soybean meal (SBM) by treated, either by heat (HJM) or by boiling (BJM), Jojoba meal (JM), to eliminate the negative effects of antinutritional factors, at 10, 20 and 30% replacing levels in diets of sea bream (Sparus aurata)) fingerlings on growth performance, nutrient utilization, body biochemical composition, middle intestine morphology and measuring of some hematological parameters of sea bream. Results indicated an enhancement in growth and feed utilization for all fish groups fed boiled followed by heated jojoba meal at 20% inclusion level compared to the control and other tested fish groups. Results of fish biochemical analyses indicate significant increase in crude protein contents in fish fed 10 and 20% HJM and 20% BJM. The present results also showed obvious increment in lipid contents as the level of JM inclusion level increase. Serum total protein, albumin and globulin levels indicated no negative effects when soybean meal was partially replaced by jojoba meal. Also, results indicate pronounced gradual decrease in serum cholesterol levels coincided with an increase in triglyceride. Middle intestine morphology examination showed significant variations in thickness of muscularis layer, villi length and width and also number of goblet cells.

“…The meal (seed plant material after removing of the oil) is rich in protein 29-30% in addition to a group of cyanogenic glycosides (cyanomethylenecyclohexyl glycosides), simmondsin and its derivatives; simmondsin-2 -ferulate, demethylsimmondsin, didemethysimmondsin, 4,5-didemthyl-4-O-␣-d-glucopyranosylsimmonsin (Elliger et al, 1974;Van Boven et al, 2000Lein et al, 2002;Bellirou et al, 2005). These toxicants could be removed (Verbiscar et al, 1980) and the meal could be used as livestock feed ingredient (Abbott et al, 1999).…”

When defatted jojoba meal is used as animal food, it causes food-intake reduction and growth retardation. Detoxification procedures by chemical, microbiological, and solvent extraction methods are reported by several authors. Here we report a successful detoxification of jojoba meal using enzymes. We establish reaction conditions that yield new meal which has the same nutritional qualities in proteins as the original meal. The enzymatic reaction gives rise to one major compound to which the structure of an amide is assigned on the basis of IR, 1H and 13C NMR spectra. The effect of the resulting jojoba meal on the food intake in rats is checked. In contrast, the detoxified meal containing the amide derivatives shows no toxicological activity since rats receiving oral administration of the obtained meal show normal growth. Thus, it is expected that this meal could be used as an animal feed ingredient.
