Problems solved by technology

[0003] After the lotus root is dug out of the water, the storage time is only about a week, and it is very prone to problems such as browning, shrinkage, aging, and mildew, which is not conducive to the storage and transportation of the lotus root; moreover, the lotus root is the aquatic economic crop with the largest cultivation area in my country. In the season when lotus root is mature, the output of lotus root is very large, and it cannot be consumed in the production area and surrounding areas for a while; therefore, it is extremely important to solve the problem of keeping fresh lotus root

Embodiment 1

[0025] Embodiment 1: the wood wool fresh-keeping method of lotus root, general process is as follows:

[0026] S1. The newly dug lotus root is cleaned and drained, and then sterilized in high-temperature steam. The steam temperature is 150°C, and the treatment time is 25s;

[0027] S2. Immerse the lotus root in S1 in the color-protecting agent solution prepared with citric acid, phytic acid, tetrasodium diphosphate, and calcium chloride at a ratio of 5:3:5:5 for 1 min, drain and wait for packaging;

[0028] S3, soak the long and thin wood wool planed in a sodium chloride solution containing citric acid, sodium sulfite, sodium benzoate, and disodium edetate for 30 minutes and take it out;

[0029] S4, storing the lotus root to be packaged in S2 together with the soaked wood wool in S3, and storing.

Embodiment 2

[0030] Embodiment 2: the wood silk fresh-keeping method of lotus root, general process is as follows:

[0031] S1. After cleaning and draining the newly dug lotus root, soak it in a high-concentration sodium chloride solution for 15 minutes to carry out sterilization treatment;

[0032] S2. Immerse the lotus root in S1 in the color-protecting agent solution prepared with citric acid, phytic acid, tetrasodium diphosphate, and calcium chloride at a ratio of 5:3:5:5 for 10 minutes, drain and wait for packaging;

[0033] S3, soak the long and thin wood wool planed in the wood wool soaking solution containing citric acid, phytic acid, tetrasodium diphosphate, calcium chloride, sodium hypochlorite for 45min and take it out;

[0034] S4, put the lotus root to be packaged in S2 and the wood wool soaked in S3 into a plastic bag, and seal it for storage.

Embodiment 3

[0035] Embodiment 3: the wood silk fresh-keeping method of lotus root, general process is as follows:

[0036] S1. After cleaning and draining the newly dug lotus root, soak it in sodium sulfite solution for 10 minutes to carry out sterilization treatment;

[0037] S2, immerse the lotus root in S1 in the color-protecting agent solution prepared by citric acid, phytic acid, tetrasodium diphosphate, and calcium chloride in a ratio of 4:3:5:5 for 5 minutes, drain, and wait for packaging;

[0038] S3, soak the long and thin wood wool planed in a sodium chloride solution containing citric acid, sodium sulfite, sodium benzoate, and disodium edetate for 35 minutes and take it out;

[0039] S4, lay the wood wool soaked in one deck S3 earlier in the wooden box, put the lotus root to be packaged in S2 on the wood wool layer, put 3 layers, spread the wood wool soaked in S3 again on the lotus root, make the wood wool The shredded silk and lotus root are alternately stacked and stored.

Abstract

The invention provides a wood-wool preservation method of lotus roots, and relates to the technical field of vegetable preservation. The wood-wool preservation method comprises processes as follows: S1, the lotus roots which are just digged out are cleaned, drained and then sterilized; S2, the lotus roots in S1 are soaked in a color retention agent solution for 1-20 min, and the lotus roots are drained for packaging; S3, long and thin wood wool obtained by planing is soaked in a wood-wool soaking solution for 5-60 min and then taken out; S4, the to-be-packaged lotus roots in S2 are stored andpreserved with the wood wool soaked in S3 together. Compared with the prior art, the method has the beneficial effects as follows: the lotus roots can be effectively prevented from browning, air shrinkage, aging, mildewing and rotting, the freshness lifetime of the lotus roots is prolonged and reaches 6 months or longer, and storage and transportation of the lotus roots are convenient. The usage quantity of a sterilizing agent and a color retention agent is small, and original-flavor preservation of the lotus roots is realized; the wood wool is light, easily available and easily separated fromthe lotus roots.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping vegetables, in particular to a wood wool fresh-keeping method for lotus roots. Background technique [0002] Lotus root is a high-quality vegetable that integrates fruits, vegetables, and medicines. It has high nutritional value and medicinal value; the nutritional components of lotus root mainly include starch, sugar, protein, fat, and lecithin. [0003] After the lotus root is dug out of the water, the storage time is only about a week, and problems such as browning, shrinkage, aging, and mildew are prone to occur, which is not conducive to the storage and transportation of the lotus root; moreover, the lotus root is the aquatic economic crop with the largest cultivation area in my country. In the season when the lotus root is ripe, the output of the lotus root is very large, which cannot be consumed in the production area and surrounding areas for a while; therefore, it is extremely import...
