Hello everyone, I' am working on how to detoxificate de jatropha curcas oil press seed cake, as we know we have to eliminate de curcin, my opinion is that the high crude protein level would be more interesting using for animal feed than bio fertilizar. Has anybody experience in this process.

I spoke to my senoirs in this field here Ghana with regards to this topic and they think it is possible,but a lot of research work is needed.The non-toxic veriety according to my study is best for this purpose.

Jatropha is a genus of approximately 175 succulents, shrubs and trees (some are deciduous, like Jatropha curcas L.), from the family Euphorbiaceae. Plants from the genus natively occur in Africa, North America, and the Caribbean. Originating in the Caribbean, the Jatropha was spread as a valuable hedge plant to Africa and Asia & INDIA by Portuguese traders. Some species of cultural and/or economic interest include: J. aconitifolia, leaves of this tree were boiled and eaten by the Maya. J. cuneata, stems are used for basket making in Mexico. J. curcas, also called physic nut, is used to produce the non-edible Jatropha oil, for making candles and soap, and as an ingredient in the production of biodiesel. The trees produce 1600 liters of oil per hectare. The cakes remaining after the oil is pressed out can be used for cooking, for fertilizing, and sometimes even as animal fodder, while the seed husks can be used to fuel generators. Large plantings and nurseries of this tree have been undertaken in India by women's Self Help Groups, using a system of microcredit to ease poverty among the nations semi-literate population of women. Extracts from this species have also been shown to have anti-tumor activity. The seeds can be used as a remedy for constipation, wounds can be dressed with the sap, and the leaves can be boiled to obtain a malaria and fever remedy. J. gossypifolia, also called bellyache bush, its fruits and foliage are toxic to humans and animals. It is a major weed in Australia. J. podagrica, was used to tan leather and produce a red dye in Mexico and the Southwestern United States. May also be used as a house plant. Uses According to Ochse (1980), "the young leaves may be safely eaten, steamed or stewed." They are favored for cooking with goat meat, said to counteract the peculiar smell. Though purgative, the nuts are sometimes roasted and dangerously eaten. In India, pounded leaves are applied near horses' eyes to repel flies. The oil has been used for illumination, soap, candles, adulteration of olive oil, and making Turkey red oil. Nuts can be strung on grass and burned like candlenuts (Watt and Breyer-Brandwijk, 1962). Mexicans grow the shrub as a host for the lac insect. Ashes of the burned root are used as a salt substitute (Morton, 1981). Agaceta et al. (1981) conclude that it has strong molluscicidal activity. Duke and Wain (1981) list it for homicide, piscicide, and raticide as well. The latex was strongly inhibitory to watermelon mosaic virus (Tewari and Shukla, 1982). Bark used as a fish poison (Watt and Breyer-Brandwijk, 1962). In South Sudan, the seed as well as the fruit is used as a contraceptive (List and Horhammer, 1969–1979). Sap stains linen and can be used for marking (Mitchell and Rook, 1979). Little, Woodbury, and Wadsworth (1974) list the species as a honey plant. Folk Medicine According to Hartwell, the extracts are used in folk remedies for cancer. Reported to be abortifacient, anodyne, antiseptic, cicatrizant, depurative, diuretic, emetic, hemostat, lactagogue, narcotic, purgative, rubefacient, styptic, vermifuge, and vulnerary, physic nut is a folk remedy for alopecia, anasorca, ascites, burns, carbuncles, convulsions, cough, dermatitis, diarrhea, dropsy, dysentery, dyspepsia, eczema, erysipelas, fever, gonorrhea, hernia, incontinence, inflammation, jaundice, neuralgia, paralysis, parturition, pleurisy, pneumonia, rash, rheumatism, scabies, sciatica, sores, stomachache, syphilis, tetanus, thrush, tumors, ulcers, uterosis, whitlows, yaws, and yellow fever (Duke and Wain, 1981; List and Horhammer, 1969–1979). Latex applied topically to bee and wasp stings (Watt and Breyer-Brandwijk, 1962). Mauritians massage ascitic limbs with the oil. Cameroon natives apply the leaf decoction in arthritis (Watt and Breyer-Brandwijk, 1962). Colombians drink the leaf decoction for venereal disease (Morton, 1981). Bahamans drink the decoction for heartburn. Costa Ricans poultice leaves onto erysipelas and splenosis. Guatemalans place heated leaves on the breast as a lactagogue. Cubans apply the latex to toothache. Colombians and Costa Ricans apply the latex to burns, hemorrhoids, ringworm, and ulcers. Barbadians use the leaf tea for marasmus, Panamanians for jaundice. Venezuelans take the root decoction for dysentery (Morton, 1981). Seeds are used also for dropsy, gout, paralysis, and skin ailments (Watt and Breyer-Brandwijk, 1962). Leaves are regarded as antiparasitic, applied to scabies; rubefacient for paralysis, rheumatism; also applied to hard tumors (Hartwell, 1967–1971). Latex used to dress sores and ulcers and inflamed tongues (Perry, 1980). Seed is viewed as aperient; the seed oil emetic, laxative, purgative, for skin ailments. Root is used in decoction as a mouthwash for bleeding gums and toothache. Otherwise used for eczema, ringworm, and scabies (Perry, 1980; Duke and Ayensu, 1984). We received a letter from the Medicial Research Center of the University of the West Indies shortly after the death of Jamacian singer Robert Morley, "I just want you to know that this is not because of Bob Morley's illness, why I am revealing this ... my dream was: this old lady came to me in my sleep with a dish in her hands; she handed the dish to me filled with some nuts. I said to her, "What were those?" She did not answer. I said to her, "PHYSIC NUTS." She said to me, "This is the cure for cancer." We found this Jamaican dream rather interesting. Four antitumor compounds, including jatropham and jatrophone, are reported from other species of Jatropha (Duke and Ayensu, 1984). Homeopathically used for cold sweats, colic, collapse, cramps, cyanosis, diarrhea, leg cramps. Chemistry Per 100 g, the seed is reported to contain 6.6 g H2O, 18.2 g protein, 38.0 g fat, 33.5 g total carbohydrate, 15.5 g fiber, and 4.5 g ash (Duke and Atchley, 1983). Leaves, which show antileukemic activity, contain a-amyrin, b-sitosterol, stigmasterol, and campesterol, 7-keto-b-sitosterol, stigmast-5-ene-3-b, 7-a-diol, and stigmast-5-ene-3 b, 7 b-diol (Morton, 1981). Leaves contain isovitexin and vitexin. From the drug (nut?) saccharose, raffinose, stachyose, glucose, fructose, galactose, protein, and an oil, largely of oleic- and linoleic-acids (List and Horhammer, 1969–1979), curcasin, arachidic-, linoleic-, myristic-, oleic-, palmitic-, and stearic-acids are also reported (Perry, 1980). Toxicity The poisoning is irritant, with acute abdominal pain and nausea about 1/2 hour following ingestion. Diarrhea and nausea continue but are not usually serious. Depression and collapse may occur, especially in children. Two seeds are strong purgative. Four to five seed are said to have caused death, but the roasted seed is said to be nearly innocuous. Bark, fruit, leaf, root, and wood are all reported to contain HCN (Watt and Breyer-Brandwijk, 1962). Seeds contain the dangerous toxalbumin curcin, rendering them potentially fatally toxic. Description Shrub or tree to 6 m, with spreading branches and stubby twigs, with a milky or yellowish rufescent exudate. Leaves deciduous, alternate but apically crowded, ovate, acute to acuminate, basally cordate, 3 to 5-lobed in outline, 6–40 cm long, 6–35 cm broad, the petioles 2.5–7.5 cm long. Flowers several to many in greenish cymes, yellowish, bell-shaped; sepals 5, broadly deltoid. Male flowers many with 10 stamens, 5 united at the base only, 5 united into a column. Female flowers borne singly, with elliptic 3-celled, triovulate ovary with 3 spreading bifurcate stigmata. Capsules, 2.5–4 cm long, finally drying and splitting into 3 valves, all or two of which commonly have an oblong black seed, these ca 2 x 1 cm (Morton, 1977; Little et al., 1974). Germplasm Reported from the Central and South American Centers of Diversity, physic nut, or cvs thereof, is reported to tolerate Slope. There is an endemic species in Madagascars J. mahafalensis, with equal energetic promise. (2n = 22) Distribution Though native to America, the species is almost pantropical now, widely planted as a medicinal plant which soon tends to establish itself. It is listed, e.g., as a weed in Brazil, Fiji, Honduras, India, Jamaica, Panama, Puerto Rico, and Salvador (Holm et al, 1979). Ecology Ranging from Tropical Very Dry to Moist through Subtropical Thorn to Wet Forest Life Zones, physic nut is reported to tolerate annual precipitation of 4.8 to 23.8 dm (mean of 60 cases = 14.3) and annual temperature of 18.0 to 28.5°C (mean of 45 cases = 25.2). Cultivation Grows readily, from cuttings or seeds. Cuttings strike root so easily that the plant can be used as an energy-producing living fence post. Harvesting For medicinal purposes, the seeds are harvested as needed. For energy purposes, seeds might be harvested all at once, the active medicinal compounds might be extracted from the seed, before or after the oil, leaving the oil cake for biomass or manure. Energy The clear oil expressed from the seed has been used for illumination and lubricating, and more recently has been suggested for energetic purposes, one ton of nuts yielding 70 kg refined petroleum, 40 kg "gasoil leger" (light fuel oil), 40 kg regular fuel oil, 34 kg dry tar/pitch/rosin, 270 kg coke-like char, and 200 kg ammoniacal water, natural gas, creosote, etc. In a startling study, Gaydou et al. (1982) compare several possible energy species with potential to grow in Malagasy. Oil palm was considered energetically most promising. Yields and Economics According to Gaydou et al (1982), seed yields approach 6–8 MT/ha with ca 37% oil. They calculate that such yields could produce the equivalent of 2,100–2,800 liters fuel oil/ha (see table under Energy). In Madagascar, they have ca 10,000 ha of purging nut, each producing ca 24 hl oil/ha for a potential production of 240,000 hl (Gaydou, et al, 1982). Just try the best bio diesel crop Jatropha Curcas.

Try thinking it as a fuel - Not as animal feed or fertilizer – Check out the calorie content 5,000 +. More value. Peter

5,000 a significant caloric value equivalent to lowgrade coal, making jatropha business economically viable. Could you show me any reference/website link describing caloric analysis of seed cake, many thanks. Rus

I'm working with Jatropha curcas for biofuel with a group in Costa Rica. We are trying to look upon the press cake as the principal product in an effort to conteract the expense of hand harvesting the fruit. The use of the press cake as a fuel or fertilizer seems to be very wasteful. It represents a reservoir of energy and fixed nitrogen in the form of proteins. It would far more profitable to use it as animal feed then put the manure in biodigesters to get energy. The problem is the double toxin systems, curcin and the phorbol esters.

 

The non-toxic variety is very hard to get seeds of other than going to Mexico and finding them. This variety originated near Veracruz and is mostly planted in Quintana Roo Provence. There the seeds are roasted and sold as food for people.

 

I don't think that there is a completely non-toxic variety. I think that there is a variety that has very low levels of one of the two toxins and that the other toxin is destroyed by heating, but I can't find out which is which.

 

My work must be limited to the standard plants. Curcin is a protein and as such is subject to being destroyed in various ways. The press cake can probably be made non-toxic by being used as a fermentation feed stock to produce ethanol. But then its value as animal feed is greatly reduced. I would also like to use it to make silage since that too is a fermentation process but that preserves much of the original protein content. The question is if the silage process would eliminate toxicity.

 

Oh yes, the use of press cake for animal feed necessitates the dehulling of the seed before pressing for the oil. This also increases the oil yield per expresser load and reduces wear and tear on the equipment.

Hallo Hannah,

lucky to find you! I´m looking to find J.C.growers in Filipinas, cause a friend of mine who is a great expert in engine conversion to svo has moved there and is interested to make a contact and perhaps work together.

If you are interested, drop me a line.

Saludos

Hallo Peter,

not everybody agrees with you.

Followiing K.Becker from Hohenheim University, detoxified seed will add between 325 and 375 $/ha of value to the cultivation- they are working at high speed on the techniques of detoxication in their labs.

Good morning (my side) Hannah,

I never got this mail.

If anyone can help you with varieties it´s Reinhard Henning of bagani  www.jatropha system. de

There are many crosslinks on that site.

If you don´t find any help there, I could try it with a pereson in Argentina, but he is also very busy.

Luck!

hola rolf,

i wonder where that email got to - i sent it thru the "contact by email " option. .  will give it another try.

anyway , i wrote to ask about possible working/business arrangements your friend might have in mind.  i also mentioned that i have several friends who have also just started on jathropa curcas farming.

yesterday, a biodiesel law has  been signed  here in the philippines requiring  motor vehicles to use biodiesel so interest in jathropa propagation has  become even higher here

thank you so much for the  website tip/help

Hola Hannah,

se sigue hablando algo de español en las Filipinas ?

I talked to my friend , but he is too busy at present and couldn´t handle any more.

I´m shure he can help you with converting engines to SVO. Look, I do not at all believe in biodiesel for some regions and reasons.

After all I´ve seen, it´s much easier and less costly to use svo with the right filtering/refinement proceedure.

More so in warm countries.

But I could see whether a joint busynes between us could work out. We need vegoil and we are buying it from wholesellers who control the market.  We would much more prefer to buy it directly from loyal producers and share the profit.We offer substancial help to people/cooperatives/organizations that are able to produce a certain output of oil.Try this mail : energiesnaturals@gmx.de

and tell me more about your plans.

hasta luego 

Rolf
