Alginate Extraction

<p class="Mabstract">A microwave hydrothermal treatment was used for the chemical production of lactic acid from alginate extracted from the brown seaweed <em>Padina Durvillaei</em>, collected in the coastal area of Ecuador. The microwave hydrothermal treatment was studied through a response surface methodology based on the Box-Behnken design, using temperature, reaction time, and catalyst concentration as the manipulated variables and the yield as a response factor. The characterization of alginate was performed by Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA). The lactic acid produced was quantified using Gas Chromatography - Ion Mobility Spectrometry (GC-IMS). The results show that temperature and catalyst concentration played the most critical roles in alginate extraction and lactic acid production. The optimal experimental conditions for alginate extraction from brown seaweed were: temperature = 92.91°C, time = 110.81 min and catalyst (Na<sub>2</sub>CO<sub>3</sub>) concentration = 2.60%, with a yield = 29.19%. Although the experimental evidence indicates a positive influence of microwaves' use on the production of lactic acid from alginate through hydrothermal treatment, a new study considering temperatures above 220°C and reaction times below 60 min should be developed.</p>

Perturbation Plot

This paper discusses the effects of two main parameters (pressure and temperature) in supercritical carbon dioxideextraction of Sargassum sp. through response surface methodology (RSM). Perturbation plot shown significant effects of all process parameters on the yield of extract. An experimental design software was designated to achieve optimization on the process situations pertaining maximum extraction yield. The optimal conditions perceived were at pressure of 4500 psi and temperature of 65°C. The highest yield of extract achieved was 2.7 mg-extract/g-dried sample under the optimum conditions. The yield of extract was then further analysed via Gas Chromatography Mass Spectrometry (GCMS) and it was found that Sargassum sp. contains sterols, pentadecanoic acid, 14-methyl ester, 9-Hexadecenoic acid, methyl ester and phytol which are the constituents of bioactive compounds and antimicrobial properties.
