“…The variance of the quadratic regression model showed that the determination coefficient (R 2 ) was 0.9309, indicating that the calculated model was able to explain 93.09% of the result in the case of AOP yield. 25 The optimum extraction conditions of AOP were as follows: liquid-solid ratio of 15.39 : 1; extraction time of 4.28 h and extraction temperature of 59.96 C. The prediction yield of AOP was estimated to be up to 5.84%. The extraction experiment was repeated three times under the optimal extraction condition (4.3 h, 60 C, and liquid-solid ratio of 15.4 : 1) to verify the reliability of the results, and the extractive rate of AOP was 5.56% (Table 5), which was very close to the predicted value.…”

“…The most important profit of RSM is reduction in the number of experimental trials. For this methodology, there are two methods are available called Central Composite Design (CCD) and Box-Behnken Design (BBD) (Liu et al 2011;Yu and Chao 2013). In this study, two different methods of RSM were used to optimize and study the effect of independent variables such as extraction time (A), extraction temperature (B) and sonication amplitude (C) for extraction of polysaccharides.…”

The aim of this study is to evaluate optimum process conditions for water soluble polysaccharides (WSP) of plant waste materials such as hazelnut skin by using response surface methodologies (RSM). Polysaccharides from hazelnut skin were extracted by means of probe type sonication system using distilled water as a solvent with several sonication time, temperature and amplitude. Response surface models were applied by both Box–Behnken Design (BBD) and Central‐Composite Design (CCD) for determining optimal condition which satisfies both maximizing polysaccharide yield and minimizing applied energy for sonication. Results showed that both BBD and CCD models represented the system with high regression coefficient (R2 > 0.95) and optimum conditions are 16.15 min, 45C, 50.29% amplitude with 0.733 desirability, 15.97 min, 45C, 47.27% amplitude with 0.712 desirability, respectively, for designs. Results of given conditions are 1.74% yield and 78.75 kJ consumption for BBD and 1.64% yield and 71.68 kJ for CCD. These results were validated by comparing experimental results at 15 min, 45C, 50% amplitude. As a consequence, it was observed that selected statistical models represent the system with a high accuracy and associating scores of each optimal condition is close enough to experimental results. Practical Applications Hazelnut skin is accepted as a waste material and there is no known application area in food industry. Although this waste can be utilized as bioactive polysaccharide source, extraction procedure requires enzymatic and chemical treatments. Sonication can be applied to extract water soluble polysaccharide from hazelnut skin and this method can be applied practically for further studies. Because during polysaccharide extraction, sonication improves uniform heat distribution and enhances mass transfer while decreasing activation energy due to the increase in particle velocity, intense mixing, cell disruption and partial hydrolysis. These effects make sonication profitable tool to obtain bioactive polysaccharides from plant waste materials. RSM is an easy way to organize experiments and optimize complex system such as extraction. On the other hand BBD design is easier and more applicable then CCD especially when the process has some concerns such as difficulties to adjust required level of parameters for CCD.

“…When the ratio of water to sample was increased from 10:1 to 25:1, the extraction yield correspondingly increased from 10.1% to 15.5% and reached the maximum as a result of the increasing in the driving force of the increasing solvent molecules. [3233] The yield of PGF indicated a descending tendency subsequently. Thus, the ratio of the water to the sample (25:1) was considered to be optimal in this experiment.…”

Background:This research is among the few that has been conducted on the feasibility of subcritical water extraction (SWE) as a rapid and efficient extraction tool for polysaccharides.Objective:The aim of the study was to extractand optimize the parameter conditions of SWE of polysaccharides from Grifola frondosa using response surface methodology.Materials and Methods:In the study, SWEwas applied to extractbioactive compounds from G. frondosa. A preliminary analysis was made on the physical properties and content determination of extracts using SWE and hot water extraction (HWE). Analysis of the sample residues and antioxidant activities of the polysaccharides extracted by SWE and HWE were then evaluated.Results:The optimal extraction conditions include: extraction temperature of 210°C, extraction time of 43.65 min and the ratio of water to raw material of 26.15:1. Under these optimal conditions, the experimental yield of the polysaccharides (25.1 ± 0.3%) corresponded with the mean value predicted by the model and two times more than the mean value obtained by the traditional HWE. The antioxidant activities of polysaccharides extracted by SWE were generally higher than those extracted by HWE. From the study, the SWE technology could be a time-saving, high yield, and bioactive technique for production of polysaccharides.
