Pineapple juice extraction typically involves selecting ripe fruits, followed by washing, peeling, and core removal. The flesh is then chopped into manageable pieces and subjected to mechanical pressing or centrifugation to extract the juice, which undergoes filtration to remove pulp and fibers. In industrial settings, processes may include enzymatic treatments, clarification steps, and sterilization (e.g., pasteurization or HPP) to ensure safety and stability, culminating in aseptic packaging for distribution.
