Fuel from renewable sources has been an excellent alternative to mineral diesel fuel, either as a substitute or an additive, after the transformation process of oil into biodiesel. Jatropha (Jatropha curcas L.) is considered a good option since it produces high-quality oil. The aim of this study was to evaluate the quality parameters of samples of physic nut oil processed at different temperatures, as well as to characterize the byproduct press (seed and cake). For this purpose, we evaluated several properties of the oil including acid index, saponification, peroxides, humidity, index of impurities insoluble in ether, ash content, relative density, refractive index, Kreis reaction, color, and mineral content. We also evaluated several properties of the grains and press cake including humidity, ash content, protein content, lipids, fibers, carbohydrates, and minerals. A completely randomized design was used to achieve the results, with three extraction temperatures (70°C, 90°C, and 110°C). Descriptive analysis, normality, analysis of variance, and Tukey's means comparison test were employed at a 5% significance level. Pearson's linear correlation coefficient was also applied. The extraction temperature of 90°C resulted in significant changes in the physical-chemical properties of the oil and press cake.

“…Vidal et al (2017) stated that the extrusion process improves significantly the apparent and dry matter digestibility coefficients, raw energy and essential and non-essential amino acids of the wheat-based diet in the Nile tilapia. Flora et al (2023) demonstrated that feeding the Nile tilapia with diets containing extruded jatropha leads to final weight gain. Also, , in a similar study, demonstrated that the extrusion process improves the nutritional values for Salvelinus malma, being able to substitute up to 50% of extruded soybean without affecting growth of organisms.…”

Background: Jackfruit seeds have been studied in the pharmaceutical industry, one way of exploiting the potential of this ingredient could be as a protein source in the elaboration of fish food. Jackfruit seeds were subjected to different processes to obtain meals to be added to the diet of Nile tilapia (Oreochromis niloticus). The effects of this addition on growth, elimination of antinutritional factors, and repercussion on the health of tilapia was evaluated. Method: For the bioassay of the productive yield, three experimental diets were prepared, consisting of a control diet of fishmeal and four treatments: raw jackfruit seeds (RJS), hulled jackfruit seeds (HJS), extruded jackfruit seeds (EJS) and hulled and extruded jackfruit seeds (HEJS). For the growth study, 1600-L experimental units were used. Three replicates per treatment were used, initial weight of tilapias was of 1.8±0.2 g. At the end of the feeding study, a blood sample was taken from the caudal vein, using a hypodermic syringe and EDTA as anticoagulant for the hematology (hemoglobin/hematocrit). Results: Significant differences among treatments using jackfruit seeds, subjected to hulling and extrusion (CEJS) processes, were observed in weight gain (24.3±1.1 g), whereas blood parameters, the red blood cells (RBC) count and the hematocrit (Hct) were significantly higher in the jackfruit seeds subjected to only one treatment (39.8±6.49) respect to the control diet (27.4±3.18). Regarding the MCH and MCHC variables, lower values were observed with the diets using EDJS, showing a significant diminution in the RBC concentration (13.2±2.5) compared to the control diet (19.3±4.65). The processes used for the jackfruit seeds allowed formulating diets with a higher protein quality, which resulted in an increment in weight gain, without observing any effect on the health indicators and nutritional status of fish.

“…After this level, animals showed a lower average daily weight gain, average daily feed intake, and feed conversion ratio. More recently, Flora et al [91] in a feeding trial using tilapia reported that JSC treated with chemical and extrusion techniques when included at levels up to 12% in the total diet reduced the growth performances of fish and high mortality rates were detected. In this study, the concentration of phorbol esters in the treated cake attained 0.023 mg/g and it reached 2.76 mg/kg of diet at the highest inclusion level.…”

Jatropha seed cake (JSC) derived from Jatropha curcas seeds is a by-product of biodiesel production and, due to its high protein content, has been considered as a potential animal feed ingredient. However, the presence of toxic compounds such as phorbol esters and other anti-nutritional factors limits its use in animal feeding. Several detoxification approaches have been used to tackle these constraints and this review aims to summarize the recent advances in JSC treatment aiming to enhance its potential as an animal feedstuff. The review first provides an overview of the structure and composition of phorbol esters and other anti-nutritional compounds, discussing its toxic effects on different animal species. It then explores several detoxification methodologies giving special emphasis to its effects on the nutritional composition of JSC and on the use of the treated substrate as a feed ingredient in fish, poultry, pigs, and ruminants, highlighting their growth performance, nutrient utilization, and animal health issues. Overall, the review concludes that these treatments hold great potential for the detoxification and utilization of JSC as an animal feed ingredient. However, further research is needed to optimize the treatment conditions, evaluate the economic feasibility, and assess the long-term effects of treated JSC on animal health and product quality.
