The best way to keep fresh food from spoiling on a backpacking trip is to wrap the perishables in plain brown paper bags or kraft paper. This allows air to circulate and kill the anaerobic bacteria responsible for the spoilage. Never wrap in plastic wrap, foil or zip locks, which should be reserved for dry foodstuffs. Be sure the veggies or meat is dry before wrapping. The paper can be used for scrubbing pots or starting fires after its role as packaging is finished.
