Numerous studies are nowadays undertaken across the world laboratories on turmeric and show its excellent virtues in various fields such as medicine, pharmacology, cosmetics, and so forth. In this paper, to enlarge the domain of scientific knowledge, a kinetic and thermodynamic behavior of curcuminoid extraction from Curcuma longa L has been investigated in the dilute medium using ethanol as solvent under a magnetic stirrer. Through the KUNYIMA method, by means of the KUNYIMA first law, the global kinetic constant has been calculated at 250 rounds per minute (rpm) and the data have shown its Constance at 500 rounds per minute at the same temperature (27.5 °C). The kinetic constant can serve to build a commercial tank of production of curcuminoids using the sizing factor to endow the Democratic Republic of the Congo with its home technology of curcuminoids extraction as is hereby discussed. Extraction enthalpy and entropy have been calculated in a closed system using the Arrhenius relation. The results of enthalpy indicate that the extraction of curcuminoids is an endothermic phenomenon. This endothermic behavior of the extraction of curcuminoids in ethanol under a magnetic stirrer probably suggests the predominance of the enol form of curcumin in presence of its tautomeric ketone form. Also, the extraction of curcuminoids in ethanol is an endothermic phenomenon and this last phenomenon probably suggests its non-bioavailability. The energy promoting solubilization of curcuminoids arises from the solvent, under a magnetic stirrer, that can meet its alike with the hydroxyl group (like dissolves like). The value of the variation of entropy has evidently suggested the disturbance of the natural order after extraction. Note that KUNYIMA's second law has been hereby announced.

“…To maintain the temperature constant during the experiment, the heating skullcap has been covered of aluminium paper as heat insulating. The ambient temperature has been 22-23°C [18,19,20,21]. After a given extraction time, the cartridge is taken up to be dried in the drying oven at 50°C during 24 hours in order to remove solvent traces.…”

“…It can be recalled that KUNYIMA method in short is the reasoning leading to understand a phenomenon and to mathematize it. So, the study of extraction of oils has been mathematized for the first time by Dr. Anaclet KUNYIMA BADIBANGA, Ordinary Professor, Faculty of Sciences, University of Kinshasa (UNIKIN) through the formula (1) below [18,19].…”

Background: The very rich vegetable patrimony of Democratic Republic of Congo (DRC) demands a local abundant production of its fruits, roots and seeds by means of appropriate technology to relieve somewhat the problem of population health because indeed those fruits, seeds, roots and leaves are reputed to have very excellent virtues in various fields such as medicine, pharmacology, cosmetic products, food and so forth. Prior to this work papers have been published on Gourd seeds oil and Moringa seeds oil extractions in order to size a continuous stirrer pilot tank of extraction. KUNYIMA method has been successfully used and is still successfully used in this present article concerning sesame (Sesamum indicum L.) seeds oil extraction in dilute medium. Aim and Objective: In this paper it can be seen the reasoning leading to KUNYIMA method is relevant and can be used to size commercial tank giving thus home rational technology. Methodology: The Soxhlet extraction of oil from sesame (Sesamum indicum L.) seeds has been performed in dilute medium using petroleum ether as solvent. Results: The obtained results are satisfactory and are perfectly in agreement with the proposed model. Commercial tank construction on rational calculation is now possible. Conclusion: KUNYIMA method once more is valid and allows to calculate the sizing factor needful to determine the reactor optimal volume.

“…In our previous work [1,2,3], it was shown that gourd seeds like, pumpkin, sesame and Moringa are made up of Chemical compounds. These compounds are of particular importance in the health of the populace as recommended by several studies [4,5,6,7,8,9,10,11,12].…”

Background: Kinetic and thermodynamic studies of the extraction of oils from pumpkin seeds, sesame seeds and Moringa seeds have been carried out at temperatures of 56 and 54°C. The extraction process was found to be exothermic and the kinetic constants in the three cases determined. It was also observed that the rate of extraction was dependent on extraction time and structural organization of the seeds. The kinetic constants are expected to provide information on the structural organization (crystalline, smectic, nematic or amorphous) of the seeds generating these oils. The enthalpies and entropies of extraction were calculated and a comparison of the kinetic and thermodynamic parameters obtained in the 3 cases was made. Aim and Objective: This work was designed to extract oils from pumpkin, sesame and Moringa seeds and to determine the kinetics and thermodynnamics of the extraction process at the given temperatures using petroleum ether as solvent. Methodology: Ten grammes of seeds powder have been introduced in cellulose porous cartridge of 33 X 205 mm and all has been put in soxhlet extractor. In a 1000 mL thrice necked bahloon- flash fitted of a thermometer, 450 mL of petroleum ether (40°-60°c, ϱ=0,65 kg/L) have been introduced as solvent. The fitting out of soxhlet has been done on heating skull cap (mark thermo scientific) in fixing temperature at 56°C(or 54°C for sesame) in balloon flask during a given extraction time. To maintain the temperature constant during the experiment, the heating skull cap has been covered of aluminium paper as heat insulating. The ambient temperature has been kept at 22-23°C. After a given extraction time, the cartridge has been taken up to be dried in the drying oven at 50°C during 24 hours in order to get rid of traces of solvent. The oil-solvent mixture collected in the 1000 mL thrice necked balloon-flask is submitted to rotary evaporator to remove the solvent and the balloon flask with extracted oil is introduced in the drying oven at 105°C during 3 hours to eliminate totally all the traces of humidity. After this step the balloon flask with oil is cooled in a dessicator and weighed. The difference between the balloon flask containing oil and the empty balloon flask determines the extracted oil mass at a t time in gramme. Results: The kinetic constants, enthalpies and entropies of the extraction process of the oils from the three different seeds were calculated and compared. In all cases, the rate of oil extraction was found to be directly proportional to time of extraction and structure of the seeds. Conclusion: The kinetic and thermodynamic study of the extraction of oils from pumpkin, sesame and Moringa seeds show that the extraction was an exothermic balanced phenomenon. The energy thus released by this operation can be used to perform mechanical or electrical work. As for the kinetic constants, they are greater in an amorphous body where the entropy is greater. In such a case, the oil extracted was much more under the same temperature and pressure conditions for a given solvent. Under these conditions, the extraction was dependent not only on time, but also on the structural organization of the material generating the oil.
