Orange juice contains a high amount of vitamin C, dietary fibre and calcium. Oranges are available year round in grocery stores, which makes it convenient to squeeze fresh juice from the fruits. Freshly squeezed orange juice only lasts for 2 to 3 days in the refrigerator. Prolong the shelf life of the orange juice by freezing it. When you want to drink or use the juice, simply place it in the refrigerator to thaw.
Run hot water over the oranges and scrub on the surface with a sponge or vegetable brush. Dry the oranges with paper towels. Disinfect utensils and surfaces with 1 tsp of chlorine bleach mixed with 1 quart of warm water.
Cut the orange in half. Remove the juice from the orange with a juicer that will not remove the oil from the rind. Sweeten the juice if you desire by adding 2 tbsp of white sugar for every quart of fresh-squeezed juice.
Pour the juice into clean, rigid freezer containers immediately. Leave 1 1/2 inches between the juice and the lid to allow for expansion. Seal the containers with tight-fitting lids.
Place the orange juice into the freezer. Label the orange juice with a date and use within 12 months for best results.
Purchase juicers specifically designed for oranges for best results. You can buy them at most speciality food or gourmet stores.
Consumption of unpasteurised orange juice by people who are susceptible to food-borne illness is not recommended. Avoid cleaning the oranges with soaps, bleach or detergents because it can contaminate the fruit. Never slice oranges on the same cutting surface as raw meats. Avoid purchasing oranges that have dull skin, soft spots, mould or bruises because they will lack in quality.
