Instead of killing all microbes, fermentation encourages "good" bacteria (like Lactobacillus) to produce acid or alcohol, which acts as a natural preservative. Examples include sauerkraut, yogurt, and sourdough.
These methods use low temperatures to slow down chemical reactions and microbial growth without significantly altering the food's cellular structure. Г©lelmiszer tartГіsГtГЎs
While preservation extends shelf life, it must be done correctly to avoid risks like botulism, especially in home canning. Modern preservation also faces the challenge of balancing shelf life with nutritional value and the reduction of artificial chemical additives. Instead of killing all microbes
With the industrial revolution came methods that allowed for longer shelf lives and easier transport: Г©lelmiszer tartГіsГtГЎs
