Is orange juice 100% orange?

What is orange juice?

Orange juice is a liquid extract made by squeezing fresh oranges. It is commonly consumed as a beverage at breakfast or can be used as an ingredient in various recipes. Freshly squeezed orange juice contains the juice vesicles and pulp from the orange fruit. Many commercial orange juices undergo processing steps like pasteurization and the addition of food additives to extend shelf life and enhance certain qualities.

Is store-bought orange juice 100% orange?

Most store-bought orange juices labeled as “100% orange juice” do contain 100% orange juice, though many also contain added ingredients. According to the FDA, for a product to be labeled as “100% juice,” it must contain 100% juice and cannot contain added sugars, colors, flavors or other non-juice ingredients. However, 100% orange juice products can still contain authorized additives including:

  • Vitamin C
  • Calcium citrate
  • Ascorbic acid
  • Potassium citrate

They may also be processed in various ways during manufacturing such as pasteurization to extend shelf life. So while 100% orange juice does need to contain 100% orange juice, there can be minor differences between fresh squeezed and store-bought varieties.

What ingredients are commonly added to orange juice?

Some of the most common non-juice ingredients added to orange juice include:

  • Sugar – Added to offset the natural tartness and acidity of orange juice.
  • Preservatives – Such as potassium sorbate to extend shelf life.
  • Flavors – Natural and artificial orange flavors are sometimes added.
  • Acids – Citric acid is often added to enhance tartness.
  • Thickeners – Like guar gum or cellulose to modify mouthfeel.
  • Vitamin C – Ascorbic acid is added as a nutrient.
  • Calcium – Calcium citrate is commonly added.
  • Coloring – Carotenes can be added to modify color.

So while 100% orange juice contains no added sugars or non-juice solids, other additives may be included. Always check the ingredient list for specifics.

Are different types of oranges used?

There are several main varieties of oranges used to make commercial orange juice:

  • Valencia – Thin-skinned, seedless oranges that are sweet and juicy.
  • Navel – Seedless oranges with a distinct navel shape at the bottom.
  • Hamlin – Smaller oranges grown early in the citrus season.
  • Pineapple – Sweet oranges with a slight pineapple flavor.
  • Blood oranges – Oranges with a bright red flesh and distinct berry-like flavor.

Most commercial orange juice consists of a blend of these orange varieties. Valencia and navel oranges are commonly used for their characteristic orange flavor. Hamlin oranges are valued for their early ripening. Specialty juices may feature a single variety like blood oranges.

Does orange juice contain fruit solids?

Yes, orange juice can contain varying amounts of solids and pulp from the orange fruit. There are a few main types:

  • Pulp-Free Orange Juice – Has all solids and pulp filtered out for a clear, pourable juice.
  • Some-Pulp Orange Juice – Contains a small amount of pulp and solids.
  • Low-Pulp Orange Juice – Contains a moderate amount of pulp and solids.
  • Orange Juice with Pulp – Contains the full amount of pulp and solids from the orange.

So while all orange juice requires 100% juice, the amount of remaining pulp and solids can vary depending on processing and consumer preferences. The presence of solids provides more texture and a fresh-squeezed taste.

How is orange juice processed and preserved?

Common processing and preservation methods used for store-bought orange juice include:

  • Pasteurization – Heat is applied to destroy microbes and enzymes that can cause spoilage.
  • Deaeration – Dissolved air is removed to prevent oxidation.
  • Chilling – Juice is chilled after pasteurization to extend shelf life.
  • Canning – Juice is hot-filled into sterile containers before sealing.
  • Freezing – Juice concentrate can be frozen for storage.
  • Preservatives – Potassium sorbate, sodium benzoate and other preservatives are added.

Proper processing is important to maintain quality and safety while also giving orange juice an adequate shelf life of 1-2 months refrigerated.

Is homemade orange juice better?

Homemade orange juice has some advantages over store-bought varieties:

  • Fresher taste – Not processed long before drinking.
  • No additives – No added sugars, preservatives, etc.
  • Customizable – Can adjust pulp level and ingredients to taste.
  • More nutrients – Less nutrient degradation from processing and storage.

However, there are some drawbacks to homemade orange juice as well:

  • Short shelf life – Only lasts 1-2 days versus weeks for store-bought.
  • Inconsistent quality – Depends on orange variety and juicing method.
  • Time consuming – Requires washing, peeling, juicing oranges.

So while fresh homemade orange juice can taste great, it may be less convenient and accessible than grabbing a carton from the store.

How long does orange juice last?

The shelf life of orange juice depends on the packaging and storage:

  • From concentrate – 10-12 months frozen, 1 week refrigerated after reconstituting
  • Not from concentrate – 2-3 weeks refrigerated, 6-8 months frozen
  • Homemade – 1-2 days refrigerated

Orange juice tends to last longer when stored frozen compared to refrigerated. Signs of spoiled orange juice include mold growth, off odors, and sour taste. Maintaining chilled storage temperatures helps extend the shelf life.

Should orange juice be refrigerated?

Yes, both store-bought and homemade orange juice should be refrigerated to maintain quality and extend shelf life. The cold temperatures help slow the growth of bacteria and prevent spoilage. For best quality, orange juice should be kept chilled at 34–40°F (1–4°C) once opened.

Refrigerating orange juice is especially important for products that lack preservatives. The vitamin C content in orange juice can also degrade more rapidly when left at room temperature for prolonged periods.

Can orange juice be frozen?

Orange juice can be frozen, either as ready-to-drink juice or as frozen concentrate. To freeze orange juice:

  • Pour freshly squeezed orange juice into freezer-safe containers, leaving 1⁄2 inch headspace.
  • Seal containers and label with date.
  • Freeze for up to 6-8 months.

To thaw:

  • Transfer container to refrigerator and thaw overnight before use.
  • Stir or shake well before drinking to redistribute settled pulp.

Freezing is a great way to stock up on fresh orange juice and extend its shelf life. Thawed orange juice may have some flavor loss but remains safe to drink.

Can you make orange juice concentrate at home?

Yes, it’s possible to make orange juice concentrate at home with just a few simple steps:

  1. Squeeze fresh oranges to make juice, collecting pulp and solids.
  2. Pour juice into a saucepan and bring to a gentle simmer.
  3. Allow juice to reduce, stirring frequently, until about 1/3 of original volume.
  4. Remove from heat and pour into freezer containers.
  5. Seal, label, and freeze for up to 1 year.

To reconstitute:

  • Thaw frozen concentrate in refrigerator overnight.
  • Dilute 3 parts water to 1 part concentrate.
  • Add more water for weaker flavor or less water for stronger flavor.

Homemade concentrate allows enjoying fresh orange juice year-round. However, the concentrate may have a subtly different flavor from commercial versions.


While store-bought orange juice labeled as “100% orange juice” must contain 100% juice, many varieties also contain authorized additives and undergo processing for quality and safety. Homemade orange juice has a fresher, natural taste but also requires more effort and has a shorter shelf life. Ultimately, the convenience and consistent quality of refrigerated carton orange juice makes it a pantry staple for many, though homemade juice can also be a delicious fresh-squeezed treat. Properly refrigerating and freezing orange juice helps maintain its quality and nutritional value.
