TL;DR: How can I pack my food so that it isn't an odor nuisance in my backpack, in a lightweight manner if animals are no issue.
In a month I will be going on a 14-day trekking trip, completely self-sustaining. That of course implies carrying a lot of food, which smells.
I do not plan to carry any strong smelling cheese but nevertheless I'm already annoyed by the smell of my backpack (and everything in it) after a day-hike if I carried any food which does have even the slightest odor.
The food in question now is stuff like salami, milk powder, beef jerky, etc.
I don't want to avoid such food because they're a great source of calories but if literally everything I will wear, use and sleep in smells like salami I surely will go crazy.
I already tried zip-lock freezer bags and vacuum bags for clothes but they both let the odor spread through the backpack.
Any recommendations are welcome but please be sure that they are available internationally, as I'm located in Germany.
