How to store lotus root? Four practical methods shared

Edible Gardening 0 views
1. Sand storage method: Choose a spot with high terrain, sheltered from wind and rain, spread a layer of fine sand on the ground. The fine sand should have a moisture level such that it forms a ball when squeezed by hand and crumbles when released. Dig drainage ditches around the perimeter. Place a layer of lotus root, then a layer of fine sand, alternating sand and lotus root in this way, stacking 5~6 layers, and cover the top with wet sand about 10 cm thick. This method generally allows storage for about 60 days. Alternatively, you can build a burial pit indoors enclosed by bricks or wooden boards, spread a 5 cm thick layer of wet sand in the pit, arrange the dug-up lotus roots with mud in order, then stack layer by layer, one layer of lotus root and one layer of wet sand, stacking 5~6 layers, and on top

2. Salt water storage method: Place the pretreated lotus root in a non-iron container, arrange in order, and submerge in 10%~15% salt water. Because salt is difficult to penetrate into the lotus root tissue, it can both preserve and inhibit enzyme activity. After storage, the flavor is no different from fresh. This method is simple, easy, and effective, allowing storage for more than half a year. The salt water can also be reused.

3. Plastic film storage method: This method only requires covering the surface of the lotus root with plastic film, and it can be stored for about 1 month. Its advantages are large storage capacity and easy operation, and it can prevent the lotus root from drying out. The disadvantages are a short storage period and relatively large losses.

4. Vacuum preservation method

(1) Color protection. Separate the treated lotus root at the joints, remove the lotus root nodes at both ends, and scrape off the skin of the lotus root. Soak the peeled lotus root in 0.8%~1.5% salt water until the lotus root becomes slightly soft.

(2) Dehydration. The lotus root has multiple holes, and during soaking in salt water, a relatively large amount of water remains in these holes. A dehydrator is needed to remove the water to prevent water droplets from appearing inside the packaging bag during storage.

(3) Packaging and vacuum sealing. Choose food-grade plastic bags with strong gas barrier properties for packaging, and vacuum seal them.

(4) Storage. For storage, choose a cool environment as much as possible and avoid direct sunlight. The suitable storage temperature is 5°C, and at this temperature it can be stored for 3~4 months.
