Question
Chapter 9, Problem 1CT
Summary Introduction
To answer:
The chemicals and sterilization methods used for long term storage of grilled cheese sandwich without decay or molds in airtight container.
Introduction:
With the use of heat and chemicals, the microbes can be eliminated. Moreover, without any use of heat or chemicals, the microbes can be controlled or stored by the means of combination of both freezing and drying. These methods can be employed in lyophilization and desiccation. The combination of these methods is employed in long term storage.
