“…Another possible mode of phytate loss during irradiation could be cleavage of the phytate ring itself (Ebrahimi-Mahmoudabad & Taghinejad-Roudbaneh, 2011). PE and phytate contents in the diets T0, T5 and T10 were within the permissible limit of 0.09 g/kg (Gogoi et al, 2014) and <5 g/kg phytic acid eq. (Spinelli, Houle, & Wekell, 1983), respectively, but the diets T15 and T20 contained PEs and phytate more than the permissible limit of monogastric animals including fish.…”

“…in SBM (75 kGy) reduced PEs and phytate by 97.60% and 71.35% (Diwani et al, 2011;Gogoi et al, 2014) and 93.55% (Sataki et al, 2013), respectively, whereas Taghinejad et al (2009) reported that gamma irradiation at 30 kGy completely removed phytate from full-fat soybean. Irradiation of DJKM reduces PEs in IJKM may be through the mechanism of oxidative degradation (Gogoi et al, 2014) and reduction in phytate probably due to the chemical degradation to lower the inositol phosphates and inositol by the action of free radicals produced by the irradiation (Siddhurajua et al, 2002). Another possible mode of phytate loss during irradiation could be cleavage of the phytate ring itself (Ebrahimi-Mahmoudabad & Taghinejad-Roudbaneh, 2011).…”

Defatted Jatropha kernel meal (DJKM) was irradiated through electron beam radiation at 25 kGy (IJKM). After irradiation, PEs and phytate were decreased by 36.67% and 55.27%, respectively, with slight reduction in total hydrolysed amino acids in IJKM. A 45‐day feeding trial was conducted to evaluate the utilization of irradiated Jatropha kernel meal (IJKM) in the diet of rohu (Labeo rohita) fingerlings. Five isonitrogenous (300 g/kg CP) and isoenergetic (15 MJ/kg GE) diets such as T0 (control, without IJKM), T5 (50 g/kg IJKM), T10 (100 g/kg IJKM), T15 (150 g/kg IJKM) and T20 (200 g/kg IJKM) were prepared and fed to fish of respective treatments. Fish fed diets containing T15 and T20 groups exhibited significantly lower (p < .05) weight gain, FCE, PER, ANPU, HSI, ISI, survival rate, nutrient and energy digestibility, than the other groups. Fish of higher IJKM fed groups (T15 and T20) also showed lower muscle moisture, protein, ash and higher muscle lipid content. The liver catalase and SOD activities significantly decreased in the higher IJKM fed groups. It is concluded that IJKM (irradiated by 25 kGy electron beam) can be incorporated up to 100 g/kg in carp feed with the replacement of 33% soybean meal and 28% ground nut oil cake without compromising growth performances of Labeo rohita.

Soap is the most useful things which we use our everyday life in various cleansing and cosmetics purposes. Jatropha oil is nonedible oil which has more benefits to soap making. It has also cosmetics and medicinal properties. But the presence of toxic Phorbol esters in Jatropha oil is the main constrains to use it. So it is necessary to search a more suitable method for detoxifying the Jatropha oil before the use as the main ingredient of soap production. This review implies a more suitable method for removing phorbol esters from Jatropha oil. Several parameters such as the % yield of pure Jatropha oil soap, TFM value of soap, total alkali content, free caustic alkalinity content, pH, the antimicrobial activity, and CMC value of general soap should be taken into consideration for soap from detoxified Jatropha oil.

Effect of raw, defatted and detoxified Jatropha seed cake on germination of green gram (Vigna radiata)

Large amount of Jatropha seed cake is generated every year as a by-product of Jatropha biodiesel industry. Jatropha seed cake significantly affected seed germination and root growth of Vigna radiata because of the presence of phorbol esters which are known to cause various physiological and morphological changes in the plant. Germination was not affected by the addition of 1 and 5% defatted seed cake while a decrease in germination rate was observed in soil containing 10% defatted seed cake. Addition of higher percentage of defatted Jatropha seed cake showed an inhibitory effect on the growth parameters of the green gram. Higher percentage of detoxified Jatropha seed cake did not affect the root length and very less reduction in the number of secondary roots observed. The vigor index was affected at 10% levels of all the treatments with detoxified seed cake having least effect. There was improvement in the number of leaves and leaf area compared to other two seed cakes. Raw Jatropha seed cake affected the chlorophyll a content while no significant changes were observed in chlorophyll b content at lower levels. Addition of detoxified seed cake concentrations at 1% and 5% level matched with the control in chlorophyll b content. It was observed that at 5% level of defatted seed cake, chlorophyll a content drastically reduced compared to raw and detoxified seed cake.
