Embodiment

[0021] A fresh-keeping method for fresh-cut lotus root, comprising the following steps:

[0022] Use the "3735" type lotus root, and select fresh lotus roots with white flesh, thick joints, no damage, and the same size. Pre-cool at 4°C for 24 hours, soak in clean water after pre-cooling, and gently scrub with a soft cloth to clean the sludge on the surface of the lotus root. Then cut off the lotus root by section, cut off the lotus root joint, peel off the lotus root skin, rinse off the residual sludge in the hole of the lotus root, and then cut into lotus root slices with a thickness of about 5mm.

[0023] Submerge the cut lotus root slices in the compound preservative for 10 minutes, take them out and dry them in the air until there is no obvious water stain on the surface of the lotus root slices. Then pack it in a box and store it at 4°C for refrigeration.

[0024] Taking 8 days of cold storage as an example, after the fresh-cut lotus root was treated with konjac polysac...

Abstract

The invention relates to a coating preservative method for fresh-cut lotus roots, particularly to a method for processing and preserving fresh-cut lotus roots by using a composite preservative prepared from three natural resource substances, and belongs to the technical field of fruit and vegetable preservation. The coating preservative method comprises the following steps: pre-cooling lotus roots without mechanical damage, washing, slicing, soaking in the composite preservative prepared from three natural resource substances konjac glucomannan, xanthan gum and phytic acid for 10 minutes, taking out, drying in air, boxing, and refrigerating at a temperature of 4 DEG C. As the fresh-cut lotus roots are preserved by using the composite preservative with konjac glucomannan and xanthan gum and phytic acid together, the color of the fresh-cut lotus roots in the preservation period can be effectively maintained, the breath strength of the fresh-cut lotus roots is effectively inhibited, the consumption velocity of nutrient substances is reduced, and aging can be delayed. In addition, the coating preservative method has the advantages of environment protection, low cost, simplicity and convenience, high operability and the like.
