Lesson 1Thermal process (hot-fill, pasteurization, retorting): process schedules, heating/cooling profiles, thermal validation basicsThis lesson covers heat treatments like hot-fill, pasteurising, and retorting for zucchini. It explains schedules, heat/cool curves, cold spots, and basic checks to ensure steady safety and quality.
