Proper packaging and storage conditions are also crucial. Beans are generally packed in perforated plastic bags or ventilated crates that allow air circulation. The ideal storage environment for green beans is between 4°C to 7°C with high relative humidity (90-95%) to prevent moisture loss and wilting.

Quality Control and Grading

Quality control during and after production ensures that green beans meet the standards required by consumers and regulatory bodies. Grading is a systematic process that categorizes beans based on size, color, shape, and defects, facilitating uniformity in marketing.

Key quality parameters include:

  • Size and Length: Beans are sorted into categories such as small, medium, and large, depending on the market requirements.
  • Color: A vibrant, uniform green color indicates freshness. Any discoloration or yellowing signals overmaturity or spoilage.
  • Texture and Firmness: Beans should be crisp and firm, with no signs of wilting or softness.
  • Defect Inspection: Pods should be free from insect damage, diseases, mechanical injury, and blemishes.

These criteria help producers and distributors maintain product consistency and consumer satisfaction.

Packaging and Distribution

Packaging plays a pivotal role in protecting green beans during transportation and extending shelf life. Modern packaging techniques focus on preserving freshness and minimizing physical damage.

Common packaging materials and methods include:

  • Perforated Plastic Bags: Allow moisture regulation and air exchange.
