Abstract
The invention relates to a vegetable processing method, in particular to boiled lotus roots. Newly dug lotus roots are cleaned, sliced, blanched in boiling water for 2-3 s and fished out and drained immediately, modified atmosphere packaging is adopted, and gas in modified atmosphere packaging bags is mixed gas of 65%-68% of CO2,2%-3% of O2 and 25%-40% of N2 in parts by volume. The lotus roots are blanched in the boiling water and subjected to modified atmosphere packaging, so that the lotus roots can keep higher brightness and lower browning index, the increasing speed of lignin and coarse fibers of the lotus roots during storage is delayed, lotus root aging is delayed, and the weight loss ratio and the rot index of the lotus roots are decreased.
Description
Technical field
The present invention relates to a kind of vegetable processing method is and in particular to a kind of boiled lotus root.
Background technology
Rhizoma Nelumbiniss are micro- sweet and crisp, can eat raw and also can cook, and are one of conventional meal dishes, can help digestion antidiarrheal, heat clearing away of whetting the appetite, and nourishing is supported
Property, prevent internal hemorrhage, be the first-class supping of women and children child old woman, valetudinarian and nourish good treasure, Rhizoma Nelumbinis contain abundant vitamin C
And mineral, there is drug effect, be beneficial to heart, have the effect of the pachylosiies that enhance metabolism, prevent, current boiled lotus root one
As be made of by Rhizoma Nelumbiniss salting, desalination, bleach, precook, cooling down, PH adjustment, pack, plus fresh-keeping liquid, sealing sterilize these techniques,
Processing routine is comparatively laborious, and the Rhizoma Nelumbiniss nutritive loss rate after process is higher.
Content of the invention
Comparatively laborious, the larger problem of Rhizoma Nelumbiniss nutritive loss for the existing Rhizoma Nelumbiniss boiled process of solution, the present invention provides a kind of water
Boil Rhizoma Nelumbiniss.
The technical solution used in the present invention is：A kind of boiled lotus root,
Take and newly dig Rhizoma Nelumbiniss, cut into slices after cleaning, pull out immediately after the blanching 2-3 second in boiling water and drain the water, using controlled atmospheric packing, be placed in
Preserve under 4-5 DEG C of refrigerated storage temperature, the gas in controlled atmospheric packing packaging bag is the mixed gas of CO2, O2 and N2, with volume
Number meter, the volume fraction of CO2 be 65-68%, O2 volume fraction be the volume fraction of 2%-3%, N2 be 25%-40%.
A kind of boiled lotus root of the present invention, through controlled atmospheric packing after Rhizoma Nelumbiniss boiling water blanching, the gas composition in controlled atmospheric packing can have
Effect reduces lipoxygenase (LOX), polyphenol oxidase (PPO), peroxidase (POD) and PAL in fresh Rhizoma Nelumbiniss
(PAL) activity, improves superoxide dismutase (SOD) and catalase (CAT) activity, so that Rhizoma Nelumbiniss keep higher
Brightness and relatively low browning index, delayed lignin in storage for the Rhizoma Nelumbiniss and coarse-fibred gather way, delayed Rhizoma Nelumbinis
Asthenia is old, reduces weight-loss ratio and the rotting mechanism of Rhizoma Nelumbiniss, also inhibits simultaneously Rhizoma Nelumbiniss storage period soluble solid, can
The decline of the content of soluble proteins and Vc, quality keeps preferably.
