Preserving Strawberry Freshness: Cold Storage Best Practices
Strawberries are highly perishable due to their high water content and metabolic activity. To maximize marketability, growers and distributors must master post-harvest cooling.
-
Pre-cooling: Strawberries should be cooled to between 0°C and 2°C (32°F - 36°F) as quickly as possible after harvest. Rapid cooling significantly slows down respiration and decay.
-
Optimal Storage Conditions: Maintain a steady temperature near 0°C. Relative humidity should be kept between 90% and 95% to prevent shriveling and weight loss.
-
Atmosphere Control: Utilizing Modified Atmosphere Packaging (MAP) or Controlled Atmosphere (CA) technology helps suppress fungal growth, extending shelf life significantly.
-
Sanitation: Cold storage facilities must be sanitized regularly to prevent the spread of Botrytis cinerea, the leading cause of post-harvest rot.
