What are some disadvantages of preservation methods for example, Canning/Bottling and also Pasterisation?

Advantages are simple i just need more of an insight.

Canning: lower nutritional value due to excessive processing, quality of products (eg veg) becomes lower due to longer cooking time.

Pasteurisation: MILK: lowers vitamin content, denatures milk proteins, destroys vitamins C, B12 and B6.
Pasteurisation: CHEESE: destroys the microbes which are responsible for the coagulation and ripening of the cheese which means they have to be replaced by artificial additives.

Hope this helps
