The Five Stages of the Cold Chain The Five Stages of the Cold Chain: Stage 1: Cooling and Chilling ( Industrial Application) Pre ‐ cooling, chilling, freezing at source. ( Some HAT countries losses 40% of its fresh fruits and vegetable produce because of the break ‐ down of the Food Chain .) Advantages: Retains Nutritional value of product, add several Days to self life, reduces food losses and improves quality and food safety.
