It’s important to understand this because the chapter is over how diabetes could have been helpful to us many millions of years ago.. The use of low temperatures to preserve foods is based on the fact that the activities of microorganisms can be slowed at temperatures above freezing and generally stopped at subfreezing temperatures..

Freezing preserves foods by preventing harmful bacteria from growing. If frozen correctly, foods will keep most of their nutrients, color, texture and flavor. Hints for freezing.
