Lab 4: Pasteurization and Sterilization Learning Outcomes • Explain the concept of food spoilage and shelf life. • Explain the principle of pasteurization and sterilization. • Analyze the parameters of High-Temperature-Time-Treatment (HTST) pasteurization. • Perform canning as a method of sterilization. • Identify how plastic and metal can be used as materials for packaging. Introduction: Experiment with pasteurization and sterilization Virtual Simulation Lab In the Pasteurization and Sterilization lab, you will help Adam, an organic farmer, to increase the shelf life of his peach juice. Together with Marie, a food scientist, you will learn the basics of food spoilage and shelf life by performing a series of spoilage detection experiments. Later, you will explore two types of heat treatment, pasteurization and sterilization, to eliminate the food spoilage in the peach juice. Finally, you will employ your knowledge to determine which type of packaging and heat treatment is suitable for Adam’s peach juice. Will you be able to eliminate spoilage in Adam’s peach juice? Questions: 1. Purpose: Why is food safety important?
