: Jackfruit straw is a part of jackfruit that does not experience pollination in the form of yellow fibers. Jackfruit straw has a composition consisting of 13.45% starch, 65.05% water. The potential content of jackfruit straw starch can be used as an alternative fuel, it was, bioethanol. This material can be converted to bioethanol through hydrolysis and fermentation processes. This study aimed to determine the effect of variations in the type of solvent and extraction time, used the type of solvent H2O, NaOH and NaHCO3 for starch which was then hydrolyzed and produced glucose as a raw material for making bioethanol. The initial content of jackfruit straw was carbohydrate of 11.5%, fat of 16.22% and protein of 8.38%. The first step was drying so that the jackfruit straw became powder with a moisture content <14%. Then extraction with a solvent to dissolve compounds that can interfere with the hydrolysis process such as fats and proteins. This research was conducted by extracting jackfruit straw powder into starch. Variation of the extraction process was the type of solvent (H2O, NaOH of 0.2%, and NaHCO3 of 0.2%) and the extraction time (5, 10, 15, 20, and 25 minutes) at room temperature. The results showed that the highest reducing sugar concentration of 2.16% was in the type of NaOH solvent for 25 minutes.

The study aimed to determine the characteristics of gelatin from water buffalo (Bubalus bubalis) skin pre-treated with NaOH and Ca(OH)2 at different concentrations (0.3 M, 0.5 M and 0.7 M) and extracted at 65˚C for 6 hrs and 24 hrs respectively. The gelatin obtained was evaluated for its moisture, protein and ash content, UV-vis absorption value, colour, emulsifying and foaming properties. The highest yield (20.25%) was observed for gelatin extracted by 0.5 M NaOH at 24 hrs extraction time. For alkaline pre-treatment, it was found that NaOH was more efficient than Ca(OH)2 in terms of preparing the skin for subsequent extraction process. The protein content of the extracted gelatin samples was in the range of 71.76% - 87.83%, showing that the varying processing conditions are sufficiently to recover protein from the raw material. Ash content for all samples was in agreement with USDA standard, which was below than 3%. The extracted gelatin had varying pH values which were from 5.47 to 7.02. The gelatin was colourless with ‘L’ values of more than 80, except for 0.7 M Ca(OH)2 at 24 hrs which showed slightly darker properties. The intensity of the UV-vis absorption spectrum showed that a high absorption peak was observed at 6 hrs of extraction time (230 – 250 nm) compared to 24 hrs extraction time. Emulsifying properties of buffalo gelatin increased with increasing concentrations of alkaline except for 0.7 M NaOH and 0.7 M Ca(OH)2 for both extraction time. Meanwhile, foam expansion of the gelatin extracted from the different extraction conditions was observed to have a significant difference (p < 0.05) for all samples. To our knowledge, buffalo skin has the potential to be an alternative source of gelatin in the diversified industrial application by modifying the extraction conditions in order to produce gelatin with desired quality.

Callicarpa candicans (Burm. f.) Hochr. (Callicarpa cana L.) is a medicinal plant that is distributed mainly in the tropics and subtropics of Asia and finds a wide range of uses in traditional medicine. In this study, we attempted and optimized the microwave-assisted hydro-distillation (MAHD) process to obtain essential oil from the leaves of C. candicans. In addition, the obtained oil was analyzed for volatile composition by gas chromatography–mass spectrometry (GC-MS) and assayed for bioactivity against several bacteria and cancer cell lines. To optimize the extraction process, response surface methodology (RSM) in combination with central composite design (CCD) was adopted. Experimental design and optimization were carried out with respect to three experimental factors including the ratio of water to raw material, extraction time, and microwave power. The optimal extraction conditions were obtained as follows: water to raw material ratio of 6/1 (v/w), extraction time 42 min, and microwave power 440 W. Composition determination of the obtained C. candicans essential oil indicated the presence of predominant components including caryophyllene <b-> (10.45%), cadinene <d-> (10.28%), gurjunene <a-> (8.95%), muurolene <g-> (8.92%), selinene <a-> (7.06%), selinene <b-> (5.59%), and copaene <a-> (5.40%). In comparison with the essential oils obtained via traditional hydro-distillation method, the essential oil extracted by MAHD exhibited superior anti-proliferative activity on all tested cancer cell lines. Current results imply that the MAHD is capable of recovering biologically-active natural products of greater quantity than that recovered by the conventional distillation.

The extraction processing of lycopene from watermelon was investigated in this paper. Based on single factor experiments, response surface methodology (RSM) was adopted to study the key parameters such as number of extraction, extraction temperature, extraction time in order to increase extraction rate of lycopene. A second order quadratic equation was established and the applicability of model and interaction involved factors on predicting the lycopene extracting content was verified. The results indicated that the optimum extraction conditions were hexane (containing 2% dichloromethane) as extraction solvent, ratio of solvent to raw material of 3:1 (mL/g), number of extraction of 2, extraction time of 1.9 h and extraction temperature of 29.8°C. Under these conditions the extracting content of lycopene was 14.71±0.22 mg/kg, which is well in agreement with value predicted by the model.

Cymbopogon Winterianus

The main objective of this study is to improve the mathematical modelling of Cymbopogon winterianus essential oil extraction by steam distillation proposed by Cassel and Vargas by minimum 5% error reduction. Two process variable of steam distillation which are extraction time and raw material state (dry or natural) has been optimized by using factorial experimental planning to obtain high yields of citronella essential oil from twig and leaves of lemongrass species Cymbopogon winterianus (C.winterianus). The optimal condition for maximum yield (0.942%) were found to be an extraction time, 4 hr, state, natural plant. The study of Cassel and Vargas was subsequently continued with five proposed kinetics model of the extraction process. The modelling of the extraction process is optimized by using one adjustable parameter of the model and the adequacy of the fit of the models to the experimental data are analyzed by using three statistical criteria that are correlation coefficient (r) ,the root mean square error (RMSE) and the mean relative deviation modulus (E). The result has shown that the mathematical model developed by Ana based on mass transfer fundamentals is the optimum mathematical model for the extraction of Cymbopogon winterianus essential oil by steam distillation.
