Objective To employ macroporous resin for deodorization of kelp pulp.Methods The effects of macroporous resin type, deodorization temperature, and deodorization time on the deodorization of kelp pulp are explored through single-factor experiments, with the results of headspace-solid-phase microextraction/gas chromatography-mass spectrometry (HS-SPME/GC-MS) as an indicator. An electronic nose is used to analyze the differences in flavor of kelp pulp before and after the deodorization with macroporous resin.Results The optimal deodorization process for kelp pulp is deodorization with 7.3% AB-macroporous resin at 51 ℃ for 2 h. At these conditions, the removal rates of alcohols, aldehydes, and ketones in kelp pulp reach 44.98%, 47.1%, and 30.31%, respectively, and that of fishy substances reaches 51.6%. The electronic nose detection results show a significant difference in flavor of kelp pulp before and after the deodorization with macroporous resin.Conclusion AB-8 macroporous resin could effectively remove fishy substances and significantly improve the flavor of kelp pulp.
