Crop preservation refers to the methods used to maintain the quality and viability of crops after harvest. This process is essential for reducing spoilage and ensuring that food remains safe and nutritious for consumption. Techniques include refrigeration, drying, canning, and the use of preservatives, which help extend the shelf life of fruits, vegetables, and grains. Additionally, crop preservation plays a vital role in food security by minimizing waste and ensuring a steady supply of food throughout the year. Organizations like the Food and Agriculture Organization (FAO) promote sustainable practices to enhance crop preservation, benefiting both farmers and consumers globally.
