In summary, the present work successfully prepared the regenerative gels through the delignification of Miscanthus sinensis based on peracetic acid treatment. Accordingly, the inner porous structure and physiochemical properties of as-prepared regenerative gels were analyzed. Most importantly, the reduction efficiency of PAHs was investigated by analyzing the components of adsorbent smoke from the process of smoking regenerative gels, which is really significant for practical smoked meats processing engineering. The porous surface and inner complicated fibrous porous structure were confirmed by morphology analysis on regenerative gels. In addition, the nitrogen adsorption isotherms of porous regenerative gels were measured and mixing state of type I and IV was obtained according to IUPAC standard to demonstrate the presence of micro-/macro-pores. 123.83 m2/g is the maximum average diameter for surface area and total volume of regenerative NaOH/Urea gels. Therefore, regenerative NaOH/Urea gels showed excellent porous property compared to the other solvents. It was found that the crystalline structure of cellulose I in regenerative gels was transformed to that of cellulose II through the FT-IR and X-ray analysis. And thermogravitimetric analysis on regenerative gels demonstrated the variation trend of weight reduction due to the thermal property. Here, 4 kinds of standard PAHs reagents (benz[a]anthracene, benz[e]acephenanthrylene, benzo[k]fluoranthene,triphenylene) were used. On the basis of GC/MS analysis, retention time of around 23 min for components of benz[a]anthracene, benz[e]acephenanthrylene, and benzo[k]fluoranthene was spent for detection. And triphenylene at retention time of 23 min was detected and confirmed. Moreover, for the benz[e]acephenanthrylene (BAP), benzo[k]fluoranthene (BbF), the component of PAHs was detected as well. When the LiBr,NaOH/Urea as solvent was used for preparing gels and the meats was processed by smoking, the types of detected components was various depending on the smoking temperature and time. Under specific condition, GC/MS analysis was conducted after recycling smoke components represented by dichloromethane. Smoke components were highly determined by different smoking conditions and the difference can be acquired by the means of burning lignin with methoxy-, propenyl-, vanillin, ethanone, and benzene and oxidation/depolymerization. Under the high temperature smoking condition, carbohydrate-based D-glucose was detected. The PAHs generated from smoking was not found. According to the results on PAHs content caused from smoking meats process using developed PAHs adsorbent, the total content in the case of NaOH/Urea beads, LiBr beads treatments decreased compared to the control and maximum adsorption property was shown in LiBr beads. For NaOH/Urea beads, B(a)P showed maximum adsorptivity while minimum was exhibited in B(a)A and CRY. Therefore, by utilizing Miscanthus sinensis cellulose, NaOH/Urea and LiBr can be the adsorbent for removing PAHs generated from smoking meats process based on regenerative gels.
