ABSTRAK: Padina sp. merupakan spesies rumput laut cokelat (Phaeophyta) penghasil alginat, namun kualitas alginat yang dihasilkan tergolong rendah dibandingkan alginofit lainnya. Metode ekstraksi jalur kalsium diduga dapat meningkatkan kualitas alginat sehingga penelitian ini perlu dilakukan. Tujuan penelitian ini untuk mengkaji apakah ekstraksi jalur kalsium dapat meningkatkan mutu alginat yang dihasilkan dari rumput laut Padina. Ekstraksi dilakukan dengan metode jalur kalsium konvensional dan jalur kalsium MAE (Microvawe Assisted Extraction). Metode penelitian yang digunakan adalah eksperimental laboratoris dengan 1 perlakuan (kosentrasi CaCl2) dan 3 taraf konsentrasi yaitu 0,5 M 1,0 M dan 1,5 M. Parameter kualitas yang dianalisis meliputi rendemen, kadar air, Kadar abu, viskositas, pH dan FTIR. Hasil uji two way ANOVA menunjukan terdapat signifikansi rendemen dengan nilai 0,007. Metode jalur kalsium MAE dengan konsentrasi 1,0 M CaCl2 menghasilkan kualitas terbaik dengan nilai rendemen (26,83%), kadar air (10,67%), kadar abu (21,83%), viskositas (11,42 cPs)  dan pH (6,77). Hasil analisis FTIR menunjukan ke-2 metode ekstraksi menghasilkan natrium alginat dengan adanya sidik jari guluronat dan manuronat pada bilangan gelombang 930-890 cm-1 dan 870-820 cm-1. ABSTRACT: Padina sp. is a species of brown seaweed (Phaephyta) producing alginates, but the quality of alginates produced is relatively low compared to other alginophytes. The calcium pathway extraction method is thought to improve the quality of alginates thus the reason of the research. This research aims to examine whether the calcium pathway extraction improves the quality of alginates produced from Padina. Seaweed extraction was carried out using conventional calcium pathways and MAE (Microwave Assisted Extraction) calcium pathways. The research method used was laboratory experimental with 1 treatment (CaCl2 concentration) and 3 concentration levels : 0.5 M, 1.0 M, 1.5 M. Quality parameters analyzed includes yield, moisture content, ash contetnt, viscosity, pH and FTIR. The two way ANOVA test results showed that there was a significance of yield value of 0.007. The MAE calcium pathway method with a concentration of 1.0 M CaCl2 produces the best quality with a yield value (26.83%), water content (10.67%), ash content (21.83%), viscosity (11.42 cPs) and pH (6.77). FTIR analysis results show that the two extraction methods produces sodium alginate in the presence of guluronate and manuronic fingerprints at wave numbers 930-890 cm-1 and 870-820 cm-1.

Alginate Extraction

Seaweed is one of the marine biological resources of Indonesia that has a high potential to produce alginate, however, the most appropiate method to extract the alginate of high quality is still unknown. This study was aimed to determine the effects of extraction methods on the quality of alginate from seaweed Sargassum hystrix and compared the extraction cost. Two extraction methods were used in this study including acidic and calcium method. The yield, moisture content, viscosity, pH, whiteness degree, functional group, ash content and extraction cost were evaluated. The viscosity and whiteness degree of sodium alginate from acidic method was 126.00±7.21 cPs and 75.27±0.58 cPs, respectively. Meanwhile the calcium method produced sodium alginate with viscosity 7.23±1.50 cPs and whiteness degree 68.95±0.18 cPs. The yield, moisture content, and ash content of alginate produced by acidic method were lower compare to that of produced by calcium method. Cost analysis showed the acidic method required higher cost. Nevertheless, these resultssuggest that acidic method produce alginate with better quality than the calcium method.

Clove Essential Oil

Background: Eugenol is the main constituent of clove essential oil. Past studies have found that clove oil has diverse uses in the pharmaceutical field due to its antioxidant, antibacterial and anesthetic properties. Objective: This work compares the performance of different extraction methods and factors and identifies the effect of the treatments on oil yields and eugenol content. Materials and Methods: Maceration, Hydro distillation, microwave-assisted extraction (MAE), and Soxhlet were performed. The best technique was identified according to yield and content. Further studies were conducted to examine the effects of different factors, such as solvent types (ethanol and methanol) and sample-to-solvent ratio (1:10 and 1:15). HPLC UV-Vis was utilized in the analysis of eugenol concentration. Results and Discussion: Soxhlet extraction provided the highest yield (39.98%) and eugenol content (15.83%), compared to other methods. The results observed from several Soxhlet extraction factors showed that there is no significant difference between the different factors. In the meantime, methanol 1:15 provided the greatest amount of yields (57.83%) and eugenol content (22.21%). In this regard, the higher ratio resulted in higher eugenol content. Conclusion: The results obtained are less comparable because the processing time, the working solvent, and the separation technique were carried out differently for each method. In the meantime, as there is no past study that compared the selected methods and factors, this study’s findings will contribute substantially to fill the gap in this field.

The Impact

The study aimed to evaluate the effects of process parameters (time and raw material weight (RMW)) of conventional (boiling for 10–45 min) and microwave-assisted (2–8 min) aqueous extraction on the color quality (i.e., lightness (L*), chroma (C*), and hue (H°) of anthocyanin –based colorants of red and Inubi sweet potato (Ipomoea batatas L.) leaves. Using response surface methodology, it was found that RMW and boiling time (BT) and microwave time (MT) generally had a significant (p < 0.05) effect on the color quality of the extract from both extraction methods. The effects were found to vary depending on the extraction method and variety of the leaves used. Both extraction methods produced a brown to brick-red extract from the Inubi variety that turned red-violet to pink when acidified. The red sweet potato leaves produced a deep violet colored extract that also turned red-violet when acidified. It is recommended that the anthocyanin content of the extracts be measured to validate the impact of the methods on the active agent. Nevertheless, the outcomes in this study may serve as baseline data for further studies on the potential of sweet potato leaf colorants (SPLC) as a colorant with functional properties.

Consumers are becoming more mindful of their well-being. Increasing awareness of the many beneficial properties of peppermint essential oil (EO) has significantly increased product sales in recent years. Hydrodistillation (HD), a proven conventional method, and a possible alternative in the form of microwave-assisted hydrodistillation (MWHD) have been used to isolate peppermint EO. Standard Soxhlet and alternatively supercritical fluid (SFE), microwave-assisted, and ultrasound-assisted extraction separated the lipid extracts. The distillations employed various power settings, and the EO yield varied from 0.15 to 0.80%. The estimated environmental impact in terms of electricity consumption and CO2 emissions suggested that MWHD is an energy efficient way to reduce CO2 emissions. Different extraction methods and solvent properties affected the lipid extract yield, which ranged from 2.55 to 5.36%. According to the corresponding values of statistical parameters, empiric mathematical models were successfully applied to model the kinetics of MWHD and SFE processes.

Abstract This paper describes a comparative study of 2 extraction methods, pressurized liquid extraction (PLE) and microwave-assisted extraction (MAE), for the determination of organochlorine pesticides (OCPs) in fish muscle samples. In both cases, samples were extracted with hexaneacetone (50 + 50), and the extracts were purified by solid-phase extraction using a carbon cartridge as the adsorbent. Pesticides were eluted with hexaneethyl acetate (80 + 20) and determined by gas chromatography with electron-capture detection. Both methods demonstrated good linearity over the range studied (0.0050.100 g/mL). Detection limits ranged from 0.029 to 0.295 mg/kg for PLE and from 0.003 to 0.054 mg/kg for MAE. For most of the pesticides, analytical recoveries with both methods were between 80 and 120, and the relative standard deviations were &lt;10. The proposed methods were shown to be powerful techniques for the extraction of OCPs from fish muscle samples. Although good recovery rates were obtained with both extraction methods, MAE provided advantages with regard to sample handling, cost, analysis time, and solvent consumption. Acceptable validation parameters were obtained although MAE was shown to be more sensitive than PLE.

The bread-making quality of forty commercial winter wheat samples, grown in the western region of the CzechRepublic, and their flours (white flours with ash content of about 0.5%) prepared in a commercial mill was studied. Standard analytical methods (ash and protein content, wet gluten), amylolytic activity measurement (falling number), rheological investigation (alveograph, gluten index), sedimentation test and laboratory baking test were used for characterization of wheats and flours. In addition NIR method was used to calculate ash, wet gluten, sedimentation value and protein content. Statistically significant correlations were found practically between all tested quality parameters of wheat and corresponding flour samples. However, the strongest correlation (r = 0.69&ndash;0.70) significant at 0.01 level exists between specific bread volume and protein and wet gluten content, determined both by standard or by NIR methods.&nbsp;
