Grape Seed Source Plant Introduction, Distribution, and Growing Environment

Grape seed extract is derived from the seeds of grapes (scientific name: Vitis vinifera). Below is a detailed introduction to the grape plant’s origin, distribution, and growing environment.

  1. Source Plant Introduction:
    Grapes are the fruit of the grapevine plant, belonging to the Vitaceae family and Vitis genus, and are a deciduous vine plant. Grapevines typically feature long tendrils, lobed leaves, and small, dense flowers, with mature fruits that can be round or oval in shape, available in red, purple, green, and other varieties.
  2. Distribution:
    Grapes are native to Europe but are now widely cultivated worldwide, including in regions of Europe, Asia, Africa, North America, and South America. Major cultivating countries include France, Italy, the United States, China, Spain, and Argentina.
  3. Growing Environment:
  • Climate: Grapes thrive in warm, humid climates with a high requirement for sunlight. Generally, they adapt well to warm summers and cold winters.
  • Soil: Grapes prefer loose, fertile, and well-drained soils with a relatively flexible pH requirement, typically optimal between 6.0-7.5.
  • Altitude: Grapes can grow in low to mid-altitude regions, typically ranging from 200 to 1500 meters, with varying degrees of adaptability to altitude across different varieties.

Grapevines are highly adaptable crops well-suited for warm, humid climates, with relatively flexible soil and altitude requirements. Due to their widespread distribution and adaptability, grapes hold significant economic and social value globally.

Processing and Storage of Grape Seed Extract

The processing of grape seed extract typically involves the following steps: First, harvesting and sorting the grape seeds, then grinding or crushing the seeds, followed by extracting the target components via solvent extraction or supercritical fluid extraction methods, and finally, filtering, concentrating, and drying to obtain the extract. For storage, grape seed extract should be kept in a cool, dry, well-ventilated area, avoiding direct sunlight and high temperatures, while preventing moisture and mold contamination to maintain its stability and quality.
