“…The central composite design (CCD) of RSM is an experimental design method that statistically analyzes the response surface produced independently or by the interaction of two independent variables affecting the responses. The CCD has the advantage of effectively estimating curvature using the center point and multiple axial points to predict the optimal conditions [ 28 , 29 , 30 ]. In this study, CCD was applied to predict the optimal UAE conditions to maximize the responses, including the RSA, TIA, and CIA, of S. thunbergii extract.…”

Sargassum thunbergii has been traditionally used as an edible and medicinal material in oriental countries. However, the skin-whitening and anti-wrinkling effects of S. thunbergii have not yet been investigated. This study was conducted to establish optimal extraction conditions for the production of bioactive compounds with antioxidant activity as well as skin-whitening and anti-wrinkle effects using ultrasound-assisted extraction (UAE) in S. thunbergii. The extraction time (5.30~18.7 min), extraction temperature (22.4~79.6 °C), and ethanol concentration (0.0~99.5%), which are the main variables of the UAE, were optimized using a central composite design. Quadratic regression equations were derived based on experimental data and showed a high coefficient of determination (R2 > 0.85), demonstrating suitability for prediction. The optimal UAE condition for maximizing all dependent variables, including radical scavenging activity (RSA), tyrosinase inhibitory activity (TIA), and collagenase inhibitory activity (CIA), was identified as an extraction time of 12.0 min, an extraction temperature of 65.2 °C, and ethanol of 53.5%. Under these conditions, the RSA, TIA, and CIA of S. thunbergii extract were 86.5%, 88.3%, and 91.4%, respectively. We also confirmed S. thunbergii extract had inhibitory effects on the mRNA expression of tyrosinase-related protein-1, matrix metalloproteinase-1, and matrix metalloproteinase-9, which are the main genes of melanin synthesis and collagen hydrolysis. Liquid chromatography-tandem mass spectrometry was used to identify the main phenolic compounds in S. thunbergii extract, and caffeic acid was identified as a major peak, demonstrating that high value-added ingredients with skin-whitening and anti-wrinkling effects can be produced from S. thunbergii and used for developing cosmetic materials.

“…Selecting the conditions that can provide the optimal clearance of suspended material by bivalves is an important step in developing effective biofiltration systems. Response Surface Methodology (RSM) is a statistical technique that can be used for designing experiments, building models, evaluating the effects of several factors and searching for optimum conditions for desirable responses (Jeong et al, ). Using RSM, the interactions and relative importance of different parameters can be evaluated using a limited number of planned experiments (Wang and Liu, ).…”

The substantial filtration capacity of freshwater mussels makes them attractive tools for environmental management. In this study, we applied a central composite design to estimate independent variables and establish optimal conditions of filtration rate and faeces production that enhance filtration of suspended organic matter by the freshwater mussel Sinanodonta woodiana. The results indicated that statistical design methodology offers an efficient and feasible approach for identifying optimal conditions for high filtration and low faeces production, using just a small number (30) of individuals. The proposed model equation takes into account the quantitative effect of variables and also the influence of interactions among variables on mussel filtration rate. Under the optimal experimental conditions (mussel size, 13.0 ± 0.2 cm; flow rate, 17.5 L/h), the experimental filtration rate of 4.47 ± 1.82 L/mussel/h showed a degree of correspondence with the predicted value of 8.4 L/mussel/h, which verified the practicability of this optimum strategy. Our findings contribute to our understanding of the context‐specific ecosystem engineering provided by mussels in natural systems, and also provides a framework for optimizing conditions for the applied use of mussels as biological filters.
