Abstract
[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.
