Abstract: Typha latifolia L.,as an aquatic vegetable, has an extremely high postharvest water content ( > 5 % ). Conventional frezing leads tocellaricecrystal damage,resulting in asoft texture and lossofcommercial value paper thawing. This study innovatively proposes afreshnessand crispness preservationtreatment method basedonthe synergistic efect of dehydration by an oil-phase medium and emulsified encapsulation.Thecore processofthis method is as folows.Clean Typha latifolia L. is briefly immersedinsoyeanoilat130~160 C to remove partofthefree water; tentransferrd tolardat3045 ΔC containing glycerylmonostearate (2~4g/kg)for immersion,forminga water-in-oil emulsified protectivesystem; subsequentlyvacuumpackaged and subjected to a hot-water activation treatment at (90±5)cC ; finally,rapidly cooled and stored frozen at (-10±2)C Experimentalresultsshow that Typha latifoliaL. processedbythis technique,after6monthsoffrozenstorage andsubsequent cooking uponthawing, exhibits no significant diference incrisp and tender texture compared to fresh samples,with he retention rate of major nutrients exceeding 85% . This paper systematically elucidates the mechanism of regulating water state andinhibitingicecystalgrowthtroughoilpretreament,providinganefectiveandindustrializablnewtechnolgialpathway for the long-term frezing preservation of high-moisture fruits and vegetables.
