Pineapple juice is manufactured from ripe pineapples.[1][7] To clean pineapples before juicing, a brush and spray cleaning machine is used to remove stains, imperfections and pesticide residue.[8] After cleaning, the fruit is put into a pineapple peeling and extractor machine to obtain pulps which are put into a spiral juice extractor.[8] A juice fine filter is then used to remove all solids, fiber and colloidal particles from the pineapple juice.[1][8]
