Plant Source, Distribution, and Growth Environment of Leek Seed Extract

Leek seeds (scientific name: Allium tuberosum Rottler ex Spreng.), also known as garlic chives, chives, and scallions, are the seeds of the perennial leek plant, belonging to the onion family (Alliaceae). Below is an introduction to the plant source, distribution, and growth environment of leek seeds.

  1. Plant Source:
    Leek seeds are obtained from the leek plant, which is a common perennial herb. Its stem is cylindrical and hollow, the leaves are flat and grow in clusters, and its flowers are white or pale purple with a distinctive garlic aroma. The leek plant is mainly consumed for its stem and leaves, while leek seeds are its mature seeds.
  2. Distribution:
    The leek plant originated in China and is widely distributed across various regions of the country, including Northeast, North China, Northwest, East China, and Southwest regions. Additionally, leeks have been cultivated and introduced to several other countries and regions, such as Japan, South Korea, and Russia.
  3. Growth Environment:
    The leek plant thrives in mild and humid environments, usually growing best in sunny areas with well-drained soil. They are highly adaptable and can grow in high-altitude mountainous regions as well as low-altitude plains. The leek plant does not have strict soil requirements, preferring loose, fertile, and well-drained soils, with some tolerance for saline-alkaline conditions.

When cultivating leek plants, sowing or transplantation is typically done in spring or autumn. During the growing period, proper fertilization and watering are needed while also focusing on pest and disease control to ensure healthy growth and yield. Leek seeds are generally harvested after the plants mature, and the seeds collected and processed can be used for consumption, medicinal purposes, and other applications.

In summary, leek seeds are a common plant seed derived from the leek plant, widely distributed with strong adaptability to growth environments. They are an important crop and a common ingredient in daily life.

Processing and Storage of Leek Seed Extract

The processing of leek seed extract typically includes the following steps: first, cleaning and removing impurities, washing the harvested leek seeds to eliminate surface dirt and residues; then drying the seeds to reduce moisture content and enhance stability; next is crushing and extraction, where the dried leek seeds are ground and then extracted using a suitable solvent to obtain leek seed extract; finally, filtration, concentration, and drying are carried out on the resulting liquid to filter and concentrate, ultimately yielding leek seed extract powder.

For the storage of leek seed extract, it is generally recommended to take the following measures: store the extract in a dry, cool, and ventilated environment, avoiding direct sunlight and high temperatures; choose well-sealed containers to prevent moisture and oxygen ingress; regularly check the condition of the extract to ensure it is free of odors and moisture; avoid prolonged exposure to air to maintain quality and stability. Proper processing and storage methods can effectively preserve the quality and efficacy of leek seed extract and extend its shelf life.
