Problems solved by technology

[0003] Leeks are widely planted in my country, but because the water content of leeks is as high as about 85%, it is difficult to store them. Generally, they can turn yellow and rot in 2 to 3 days, and lose their edible value, causing great economic losses. Therefore, a kind of leek is needed. How to keep leeks fresh

Embodiment 1

[0017] A method for keeping fresh leek includes the following steps:

[0018] (1) Removal of leeks: Choose fresh leeks, remove soil and rotten leaves, and do not wash with water to reduce the growth of bacteria, and get rid of leeks;

[0019] (2) Leek drying: spread out the impurity-removing leeks, place them on a grid rack, with a thickness of 0.8~1.2cm, and place them in a drying room in the dark, at a temperature of 22°C, a humidity of 61%, and a wind speed of 3.7m / s. Dry until the water content of the leeks is 61~63%, reduce the respiration of the leeks, retain more nutrients, and get dried leeks;

[0020] (3) Leek humidification: spray 3% sucrose solution on the dried leeks, and the spray amount is 12ml / kg based on the weight of the leeks, to inhibit the damage of microorganisms and the respiration of leeks to chlorophyll, and to keep the leeks bright and green. ;

[0021] (4) Leek packaging: Pack the humidified leeks in a fresh-keeping bag, keep the oxygen content in the fresh-...

Embodiment 2

[0024] A method for keeping fresh leek includes the following steps:

[0025] (1) Removal of leeks: Choose fresh leeks, remove the soil and rotten leaves, and do not wash with water to reduce the growth of miscellaneous bacteria, and get rid of leeks;

[0026] (2) Leek drying: spread out the impurity-removing leeks, put them on a grid rack, with a thickness of 0.8~1.2cm, and place them in a drying room in the dark, with a temperature of 23°C, a humidity of 62%, and a wind speed of 3.8m / s. Drying until the water content of the leeks is 61~63%, reducing the respiration of the leeks, retaining more nutrients, and getting dried leeks;

[0027] (3) Leek humidification: spray 4% sucrose solution on the dried leeks, the spraying amount is 13ml / kg based on the weight of the leeks, to inhibit the damage of microorganisms and leeks respiration to the chlorophyll, and to keep the leeks bright and green, you must humidify the leeks ;

[0028] (4) Leek packaging: Pack the humidified leeks in a fr...

Embodiment 3

[0031] A method for keeping fresh leek includes the following steps:

[0032] (1) Removal of leeks: Choose fresh leeks, remove soil and rotten leaves, and do not wash with water to reduce the growth of bacteria, and get rid of leeks;

[0033] (2) Leek drying: spread out the impurity-removing leeks, put them on a grid, with a thickness of 0.8~1.2cm, and place them in a drying room in the dark, at a temperature of 24°C, a humidity of 63%, and a wind speed of 3.9m / s. Dried until the water content of the leeks is 63%, which reduces the respiration of the leeks and retains more nutrients to obtain dried leeks;

[0034] (3) Leek humidification: spray dry leeks with a 5% mass fraction of sucrose solution, the spraying amount is 14ml / kg based on the weight of the leeks, to inhibit the damage of microbes and the respiration of leeks to chlorophyll, and to keep the leeks bright green. ;

[0035] (4) Leek packaging: Pack the humidified leeks in a fresh-keeping bag, keep the oxygen content in th...

Abstract

The invention mainly relate to the technical field of plantation, and discloses a leek fresh-keeping method. The method comprises the following steps: removing impurities from leek, drying the leek, humidifying the leek, and packaging the leek. The method is simple, prolongs the fresh-keeping life of the leek to 35-40 d, allows the serviceability rate of leek stored for 40 d to be 86.3%, and saves the economy cost by 14.7%; impurities are removed from the leek to remove most impurities and delayed leaves; water sprinkling is prevented, and drying is carried out, so breathing of the leek is reduced, and many nutrient components are reserved; sprinkling of a small amount of a sucrose solution inhibits damages of breathing of microbes and the leek to chlorophylls, and keeps the leek fresh and green; and the humidified leek is placed in a storage chamber, so breathing of the microbes and the leek is inhibited, many nutrient components are reserved, and the fresh-keeping time of the leek is prolonged.

Description

Technical field [0001] The present invention mainly relates to the field of planting technology, in particular to a method for keeping fresh-keeping leeks. Background technique [0002] Leek is also known as Fengben, Stallium stalactite, Longevity Leek, Aphrodisiac, etc. It has a special strong smell and is rich in volatile oil, sulfide, protein, fat, sugar, dietary fiber, vitamins and mineral elements, etc., which can enhance resistance. Antibacterial and anti-inflammatory, nourishing kidney and strengthening yang, nourishing liver and stomach, dissipating blood stasis and promoting blood circulation, moistening intestines and laxative, improving vision [0003] Leeks are widely grown in my country, but because the water content of leeks is as high as about 85%, it is difficult to store them. Generally, they can turn yellow and rot within 2 to 3 days, and lose their edible value and cause great economic losses. Therefore, a kind of How to keep leeks fresh. Summary of the inventio...
