Fruit Harvesting Techniques

Harvesting Techniques

Maturity Indices

• Used to determine the optimal harvest time for fruits
• Examples:
  • Color: changes in skin color, e.g., bananas turn from green to yellow
  • Softening: increased softness, e.g., ripe mangoes
  • Sugar content: measurement of sugar levels, e.g., sugar cane harvest
  • Acidity: measurement of acidity levels, e.g., citrus fruits

Harvesting Methods

• Hand harvesting: manual picking, often used for delicate fruits like strawberries and grapes
• Mechanical harvesting: used for fruits like apples and oranges, using machines to shake or pull fruits from trees
• Combination harvesting: combines hand and mechanical methods, e.g., using machines to shake trees and manual labor to collect fruits

Post-Harvest Handling

• Cooling: rapid cooling to slow down metabolic processes, e.g., refrigeration or icing
• Cleaning: removal of dirt, leaves, and other debris to prevent spoilage
• Grading: sorting fruits by size, color, and quality to optimize storage and transportation
• Packaging: careful packaging to prevent damage during transportation and storage

Specialized Harvesting Techniques

• Dry harvesting: used for fruits like dates and prunes, where fruits are left on the tree to dry
• Wet harvesting: used for fruits like cranberries, where fruits are flooded and collected from the water
