How to process bagged leek

(1) Washing of raw materials: Wash the young seedlings (or tender tips) with flowing water to remove mud, sand and other impurities. Rubbing is not allowed. During the cleaning process, dry leaves and debris are removed.

(2) Protecting the salt green: Wash the impurity-free raw materials with 3% refined salt, 0.1% sodium sulfite solution, soak for 30 minutes, remove, rinse and drain.

(3) Alkaline treatment: soak in 1% sodium sulfite solution for 15 minutes, remove and rinse the residual lye with water.

(4) Protecting green and crisp: Protecting green and crisp is the key process technology of bag-packing. A 0.2% zinc chloride, 0.02% sodium sulfite, and 0.05% calcium chloride mixture was kept at a vacuum of 0.09 MPa for 15 minutes to protect the green.

(5) Bactericidal and antiseptic: Chlorophyll is easily destroyed during heating process, and it is green, and it loses its brittleness and softness. In order to keep bagged leek green and brittle and avoid hot factors, 0.05% sodium benzoate solution is used to soak 30 Minutes, bactericidal anti-corrosion, can be packed after draining.

(6) Vacuum packaging: Vacuum sealed and packaged with nylon/polyethylene (PA/PE) composite bag, vacuum degree 0.085-0.095 MPa. (7) Storage: After sealing, keep at 37°C and 2°C for 5-7 days. Check for no abnormalities. If any abnormal bags are found, store them at room temperature (20°C) and sell at any time.
