2. All fruits and vegetables should be juiced raw.
3. Small seeded fruit, such as watermelon and pears, may be juiced with their seeds with the exception of papaya and apple seeds. Orange and grapefruit seeds might impart a bitter taste to your juice. Remove the large pits from fruits like peaches and nectarines, etc.
4. Peel all fruits and vegetables that are not organically grown because the peel is where most of the chemical residues can be found. While most skins of organically grown fruits and vegetables may be left on, with the exception of waxed produce, the skins of pineapples, kiwis, oranges, grapefruits and papaya should be removed.
5. Choose fresh ripe produce. Rubbery vegetables, bruised fruit, wilted greens and over or under-ripe fruits will produce juices that are neither tasty nor healthful.
6. Cut the fruits or vegetables into pieces that will fit into the mouth of your juice machine. Turn the juice machine on and push the pieces through the mouth of the juicer. As you juice, pulp will collect in a large receptacle. If you don’t clean the pulp out right away, it will develop a sour odor and tiny gnats and fruit flies may appear after 8 to 10 hours.
7. It is best to drink freshly made juices within one day.
