“…The MAE method extraction process has many parameters, including solvent type, solvent concentration, immersion time, sample volume, sample ratio, power supply value, irradiation time, stirring time, and others. The large number of variables in the experiment if optimization is carried out conventionally will result in a large number of experimental samples [9][10][11]. To reduce the number of samples, this can be done using statistics.…”

Chlorophyll extraction using the microwave-assisted extraction (MAE) method has several advantages such as fast, cost-effective, and able to result higher chlorophyll yield than any other extraction methods. Despite its numerous advantages, MAE method still suffers from a drawback related to the excessive heat generated by high power, leading to potential damage and a degradation chlorophyll yield. This research was conducted to evaluate the optimum formulation parameters for chlorophyll extraction using the Low Power Microwave Assisted Extraction (LP-MAE) method. The chlorophyll of dried Spirulina platensis was extracted following the I-optimal design. Extraction parameters to be optimized include the solvent type, soaking time, the power of microwave irradiation, and the solid-to-solvent ratio. The response parameters to be evaluated include the yield, viscosity, and total dissolved solids (TDS). We found that the highest yield of 5045.7 μg chlorophyll/g biomass was obtained from 90% methanol extraction following 1 h of soaking, irradiation power of 40 W for 5 mins, at the ratio of 1:20 (m/v). Under this condition, we observed that the viscosity of the solution was 7.6 x 10−3 Nms−2, and the total dissolved solid was 32 ppmml−1. In conclusion, chlorophyll is very susceptible to high temperatures, can be extracted using the Low Power Microwave Assisted Extraction (LP-MAE) method.
