Final answer:
Boxes of juice and liquid milk that do not need refrigeration are non-perishable items. Non-perishable items have a long shelf life and do not spoil easily. They can be stored at room temperature for an extended period without the need for refrigeration.
Step-by-step explanation:
Boxes of juice and liquid milk that do not need refrigeration are non-perishable items. Non-perishable items are food items that have a long shelf life and do not spoil easily. They can be stored at room temperature for an extended period without the need for refrigeration.
Examples of non-perishable items include canned goods (vegetables, soups, beans), dry goods (pasta, rice, cereals), and packaged beverages (juices, soft drinks).
Non-perishable items are safe for consumption even without refrigeration because they undergo processes such as canning, dehydration, or pasteurization to kill or inhibit the growth of bacteria or microorganisms that cause spoilage.
