Storage and fresh-keeping methods and techniques of garlic bolts

Garlic stem, commonly known as garlic seedling in some places, is the flowering stem of bolting garlic after vernalization, and it is an important by-product of garlic production. Garlic stalk is rich in crude protein and a variety of vitamins and minerals, delicious taste, is a kind of high-quality high-grade vegetables.

(1) Storage conditions

1. The temperature is 0-0.5 ℃.

two。 Relative humidity 90% Murray 95%.

3. Gas composition: O2, 2%, 2%, 4%, 4, 4, 4, 2, 2, 6, 6, 8%.

(2) Storage methods

1. Ice cellar storage method will cut off the old roots of the selected garlic bolts, remove the leaf sheath, 1kg a bundle into a bag, each packet of 10-15kg, tie up with a rope, enter the cellar in time.

Store the ice cubes picked in winter in the cellar for spare. When storing garlic bolts, first spread two layers of ice at the bottom of the cellar and two ice cubes on the cellar wall, and then palletize the garlic bolts on the ice cubes, a layer of ice. One layer of garlic stalk palletizing, a total of 3-5 layers of garlic bolts, the middle of each layer of garlic bolts is filled with crushed ice, the top ice is covered with rice husk for thermal insulation, the thickness is about lm, and the cellar door is sealed with mud paste. The storage of garlic bolts in the cellar was judged according to the smell and color of the effluent from the bottom of the cellar.

two。 The selected garlic stalks are bundled into small handfuls in a small bag, precooled to 0 ℃ in the precooling room, and packed into polyethylene plastic film bags with a thickness of 0.06-0.08mm, each bag is 15-20kg, which is 50% of the gap in the bag. 60%. Put the plastic bag on the storage rack and maintain the temperature in the storage at 0 ±0.5 ℃. During storage, the gas composition in the bag was determined by Euclidean gas analyzer. When the oxygen content in the bag was less than 2%, open the mouth of the bag in time to release air and put in fresh air. If there is no analytical instrument, the gas composition in the bag can be adjusted by regular ventilation. The bag mouth can be opened every 10 days in the early stage of storage and ventilated every 7 days in the later stage.

3. In the silicon window controlled atmosphere storage method, the selected garlic bolts are loaded into the storage box, and a layer of plastic film is laid at the bottom of the storage. the size of the bottom film is 20-30cm larger than that of the account body, and then the storage box with garlic bolts is stacked on the bottom film, and proper gaps should be left during stacking to ensure the circulation of cold air. The specification of the big account is generally 4.1m × 3.7m × 1.4m, the silicon window area is 1.28m2, and the garlic stalk 2000kg is stored. After the garlic bolts are stacked, the account should be deducted in time, so that the bottom film and the account body are tightly sealed, compacted with fine soil, and the suitable gas composition in the account is maintained by using the air permeability of silicone rubber. Generally, the oxygen in the account is maintained at about 13% and the carbon dioxide is maintained at about 5%, so the storage effect is better.
