Abstract: Purpose: A large amount of wasted mushroom stems are accumulated yearly by the mushroom industry. To reduce this waste, we have proposed a fractionation method to isolate several useful coproducts using reusable solvents. Methods: Coproducts were extracted by sequential solvent extraction before producing chitin-glucan complex from Pleurotus ostreatus (oyster) mushrooms. The extracted β-glucans, polyphenols, and proteins were confirmed by 3,5-dinitrosalicylic acid (DNS), Folin-Ciocalteau, and bicinchoninic acid (BCA) assays respectively. Extracted lipids were analyzed by gas chromatography-mass spectrometry (GC–MS). The chitin-glucan complex was characterized by Fourier-transform infrared spectroscopy (FT-IR), high performance liquid chromatography (HPLC), and powder X-ray diffraction (XRD). Results: The extract yield of chitin-glucan complex was 8.3%. The crystallinity index of the extracted chitin-glucan complex was 71.2% when compared to 85% for crustacean chitin. The reduced crystallinity in mushroom chitin was due to the presence of the residual β-glucans. Conclusion: The reported fractionation method uses less solvent and provides a greener alternative to producing chitin-glucan complex when compared to the conventional methods of using a large volume of harsh chemicals harmful to the environment. Further, fractionating several coproducts while producing the chitin-glucan complex will reduce the total processing cost.

Abstract: A large amount of wasted mushroom stems are accumulated yearly by the mushroom industry. To reduce this waste, we have proposed a fractionation method to isolate several useful coproducts such as β-glucans, lipids, Vitamin D, polyphenols, and proteins before producing chitin from oyster mushrooms using reusable organic solvents. The extracted β-Glucans, polyphenols, and proteins were confirmed by 3,5-dinitrosalicylic acid (DNS), Folin-Ciocalteau, and bicinchoninic acid (BCA) assays respectively. Extracted lipids were analyzed by gas chromatography-mass spectrometry (GC-MS) and chitin was characterized by Fourier-transform infrared spectroscopy (FT-IR) and powder X-Ray diffraction (XRD). The crystallinity index of the extracted chitin was 71.2% when compared to 85% for crustacean chitin. The reduced crystallinity in mushroom chitin was due to the presence of some β-glucans. Overall, the reported fractionation method uses less solvent and provides a greener alternative to producing chitin when compared to the conventional methods of using a large quantity of harsh chemicals harmful to the environment. Further, fractionating several coproducts while producing chitin will reduce the total processing cost.

YieldReaction ConditionsOperation in experiment
In water; at 60℃; for 1h; (1) Accurately weigh 247 mg of <strong>[19387-91-8]tinidazole</strong> and 376 mg of gallic acid monohydrate in a 50 mL round bottom flaskAdd 20 mL of distilled water and install a reflux unit.(2) Stir the reaction in a water bath at 60 C for 1 hour.The solution gradually changed from a colorless solution to a pale yellow solution.liquid.(3) The reaction solution was filtered through a medium speed filter paper, and the filtrate was placed in a 50 mL beaker, and the beaker mouth was covered with a plastic wrap.Three small mouths were placed with a syringe and allowed to stand for crystallization. The pale yellow powdery solid precipitated after about 24 hours and was a <strong>[19387-91-8]tinidazole</strong>-gallic acid drug cocrystal.
