英文摘要	Microcrystalline cellulose (MCC), produced by the isolation of natural cellulose, is a functional fiber polymer materials. As a relatively pure cellulose degradation product, MCC has been widely used in medicine, food and cosmetic industries. The work was aimed at the extraction of MCC from Jerusalem artichoke stalk (JAS) by acid hydrolysis using hydrochloric acid. The effects of liquid- solid ratio, temperature and hydrochloric acid concentration on the yield and the degree of polymerization (DP) of MCC from JAS (JASMCC) were optimized by response surface methodology to explore the optimum preparation conditions. The JASMCC based on the optimum conditions was characterized by Scanning electron microscopy (SEM) X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) and compared with the cellulose from Jerusalem artichoke stalk (JASC) and commercial grade microcrystalline cellulose (CMCC). The results show that the optimum preparation conditions of JASMCC were as follows: the liquid-solid ratio of 14:1, hydrochloric acid concentration of 5%, the temperature of 55 degrees C and time of 85 minutes. Under the optimum conditions, the yield of JASMCC was reached to 36.96 +/- 0.08%, the cellulose content of JASMCC was 97.80 +/- 0.06%, the level-off degree of polymerization (LODP) for JASMCC was 255 +/- 2. The structural characterization showed that the microstructural properties of JASMCC are considerably different from the original JASC. The X-ray crystallinity index of JASMCC was 63.42% higher than 47.93% of JASC. FTIR spectroscopy and SEM showed that the main component of JASMCC was pure cellulose JASMCC is rod-shaped, and cellulose crystal type is type I. JAS would be potentially used as the source for the extraction of food additive MCC.
