“…The castor bean allergen is a nontoxic and unusually stable protein that exhibits an extraordinary capacity to sensitize individuals exposed to small concentrations of the castor cake or dust from castor oil beans during the growing, harvesting and handling periods of the castor oil plant. Due to the presence of these compounds, it is necessary to detoxify the castor cake [10,15,16]. A number of physical and chemical methods for detoxifying castor seed meal have been investigated and have been reviewed by Anandan et al [15].…”

Castor oil is, as many other plant oils, a very valuable renewable resource for the chemical industry. This review article provides an overview on this specialty oil, covering its production and properties. More importantly, the preparation, properties and major application possibilities of chemical derivatives of castor oil are highlighted. Our discussion focuses on application possibilities of castor oil and its derivatives for the synthesis of renewable monomers and polymers. An overview of recent developments in this field is provided and selected examples are discussed in detail, including the preparation and characterization of castor oil-derived polyurethanes, polyesters and polyamides.

“…Ricin was not detected in the defated RSC. Barnes et al (2009) reported that the glycoprotein ricin degraded as a result of heating with sodium hydroxide. The concentration of phorbol esters in JSC was 0.93 mg/g and higher than reported by Saetae et al (2011) (0.73 mg/g).…”

Extraction of oils from castor bean (Ricinus communis L.) and Jatropha curcas L. to produce biofuel is set to increase. The produced seed cake could be applied to soil as it is nutrient rich, but might affect soil functioning. Seven soils from Chiapas, México, were amended with seed cake of both plants while CO 2 , CH 4 and N 2 O emissions and mineral N concentrations were monitored in an aerobic incubation. The concentration of phorbol esters in the J. curcas seed cake (JSC) was 0.993 mg/g while no ricin was detected in the R. communis seed cake (RSC). Application of JSC increased CO 2 emission 2.5-times, N 2 O 12.6-times and CH 4 18.4-times compared to the unamended soil, while RSC CO 2 emission 2.1-times, N 2 O 21.3-times and CH 4 2.3-times. On average, 66% of the 88 mg organic N added with JSC was mineralized and 83% of the 101 mg organic N of the RSC within 56 days. It was found that J. curcas and castor bean seed cake increased CO 2 , CH 4 and N 2 O emission and mineral N in soil, without inhibiting soil microbial activity.

“…Boiling has been effective in eliminating some antinutritive factors in seed meals (Barnes et al, 2009) as well as terpenes in leaves (Yang et al, 2007). Nevertheless, the total content of resins was still relatively high (National 'Values are means of 2 males and 2 females from 3 pens/diet (n = 12; 6/sex).…”

Nutritive value of false yam (Icacina oliviformis) tuber meal for broiler chickens

et al. 2011

False yam (Icacina oliviformis syn. Icacina senegalensis) is a drought-resistant plant in West and Central Africa that produces a large tuber with a high starch content, but it contains antinutritive factors (terpenes). The objective was to evaluate its feed value for broilers when the tuber was sun-dried (SFYTM) or boiled (BFYTM). In experiment 1, the tubers were peeled, diced, sun-dried (5 d), and milled. In experiment 2, the diced tubers were boiled (2 h), dried (8 d), and milled. Each meal was substituted for corn (Zea mays, wt/wt basis) at levels of 0, 3, 6, and 9% in a basal broiler grower diet (21% CP; 2,967 kcal/kg of ME) and fed to broiler chicks from 21 to 56 d of age, using a completely randomized design (4 treatments, 3 replicates). Each replicate had 10 chicks. Nutrient concentrations (% of DM) of SFYTM were CP (5.41), ether extract (1.60), NDF (28.61), starch (48.63), ash (2.19), and gross energy (4,067 kcal/kg of DM), and those of BFYTM were CP (6.46), ether extract (0.98), NDF (32.37), starch (43.12), ash (2.76), and gross energy (4,139 kcal/kg of DM). The contents of total resins in the meals ranged from 2.28% (BFYTM) to 3.75% (SFYTM). In experiment 1, increasing the dietary level of SFYTM linearly (P < 0.001) decreased feed intake (P < 0.001), BW gain (P = 0.004), G:F (P = 0.041), and dressed carcass yield (P = 0.011). However, in experiment 2, no differences were observed in growth performance (P > 0.05) between any of the dietary treatments. In both experiments, mortality was 2.00% or less (P > 0.05). Inclusion of each meal in the diets did not affect the health of the birds, and no adverse changes in blood hemoglobin, hematocrit, and white blood cells were observed.
