STUDY OF THE FACTORS INFLUENCING THE COLLECTION OF CELLULOSE FROM THE BY-PRODUCT OF OLD ASPARAGUS OFFICINALIS

Abstract

Agricultural by-products rich in cellulose, such as cotton shoots, corn stalks, bagasse and rice husks, are currently utilized in various applications, including producing food additives and extracting biological compounds. This study used by-products from asparagus roots to extract cellulose for functional food applications. The analysis revealed that the chemical composition of the asparagus root powder contained 73.7% fiber, with 67.9% insoluble fiber and 5.8% soluble fiber. The optimal reaction conditions for obtaining the highest cellulose mass involved the use of asparagus roots powder/NaOH solution, the concentration of NaOH, H₂O₂/NaOH solution ratio, temperature, and time were 1/30 g/mL, 6% (w/v), 0.9% (v/v), 80°C and 120 minutes, respectively.
