Question & Answer to the Presentation

Question from Mr. Rhiby Ainur Basit Hariyanto 2020.11.18 14:09:24 In the introduction of this article said that the conventional extraction method are dangerous because use dangerous organic solvents. But in the material and methods you use 300 mL of HCl, which is strong acid solution? Replies: Reply from Prof. Dr. Medyan Riza 2020.11.18 14:23:08 The advantage of MAE is time extraction and solvent requirements are relatively low compared to conventional extraction. Extraction time affects the contact between the material and the solvent, thus providing an opportunity to hydrolyze the protopectin contained in the material and will increase the yield of the pectin generated. Less HCL solvent used with the MAE method and in a low concentration Reply from Mr. Rhiby Ainur Basit Hariyanto 2020.11.18 14:34:11 Thank you so much for the explanation prof. Reply from Prof. Dr. Medyan Riza 2020.11.18 14:37:22 You are welcom, Thank you for your question Mr.Rhiby
