How to get the white stuff off mandarin oranges

5 min read

According to studies, the white stuff on mandarins is called pith and is packed with fiber and antioxidants. If the bitter taste or fibrous texture isn't for you, there are several simple methods for how to get the white stuff off mandarin oranges, from quick kitchen tricks to more advanced culinary techniques.

Quick Summary

This guide provides practical techniques for removing the bitter, fibrous pith from mandarin oranges. It covers manual scraping with tools, quick boiling to loosen fibers, and using pectic enzyme for a professional finish. Instructions are included for achieving perfectly clean, sweet segments.

Key Points

  • Pith is Safe and Healthy: The white stuff on mandarins is called pith and is edible, providing a good source of fiber and flavonoids.

  • Boil Briefly for Easy Peeling: A quick 10-second dip in boiling water loosens the pith, making it simple to scrape away with a knife.

  • Scrub with a Brush: For a simple, manual approach, soak segments in warm water and use a vegetable brush to scrub off the stringy bits.

  • Enzymes for Perfection: Pectic enzyme can be used to dissolve pith completely for a professional, perfectly clean finish, ideal for larger batches.

  • Scrape with a Spoon: A spoon or fingernail can be used for precise, manual scraping to remove stubborn pith from individual segments.

  • Don't Waste the Pith: If you're canning, the pith is high in natural pectin and can be used to help thicken jams and marmalades.

The white, spongy material clinging to mandarin segments, known as pith or albedo, can have a bitter taste that many people prefer to avoid. While completely edible and rich in nutrients, including fiber and flavonoids, its texture can be off-putting. Fortunately, several methods can be employed to achieve perfectly clean, sweet-tasting segments. The right approach depends on how many oranges you're preparing and your desired level of perfection.

Quick and Easy Methods for a Few Mandarins

For a small handful of mandarins, a simple, low-tech approach is often all you need. These methods require minimal prep and are ideal for a snack or small-scale recipe preparation.

The Warm Water and Scrub Technique

One of the simplest ways to loosen stubborn pith is by using warm water and a brush.

  • Prep: Peel your mandarin orange and separate it into individual segments.
  • Submerge: Place the segments in a bowl of warm, but not boiling, water. Let them soak for a few minutes. The warm water helps to relax the pith fibers.
  • Scrub Gently: Use a moderately stiff-bristled vegetable brush or a clean, soft toothbrush to gently scrub the white, stringy bits off each segment.
  • Rinse and Dry: Rinse the clean segments with cool water and pat them dry with a paper towel before enjoying.

The Spoon or Fingernail Scraping Method

If you prefer to work dry, your own tools can be quite effective.

  • Peel: First, peel the mandarin, leaving as little pith as possible on the segments.
  • Scrape: Using the edge of a spoon or your fingernail, gently scrape away the remaining white pith from the surface of each segment.
  • Separate: As you break apart the orange, continue to remove any remaining stringy veins.

Advanced and Professional Techniques

For those who need to prepare a larger quantity of oranges or want restaurant-quality, perfectly clean segments, more advanced techniques are available.

The Boiling Water Method

This method uses heat to quickly loosen the peel and pith from the fruit.

  • Boil: Bring a pot of water to a boil. Carefully place the whole, unpeeled mandarin into the boiling water using a heat-safe spoon.
  • Time it: Leave the orange in the water for no more than ten seconds. This is just enough to loosen the pith without cooking the fruit.
  • Cool and Score: Remove the orange and let it cool. Once cool enough to handle, use a paring knife to make four vertical slices in the peel.
  • Peel and Clean: The peel and most of the pith should now come off easily in four large sections. Scrape off any remaining pieces with your fingernail or the knife.

The Pectic Enzyme Method

For professional-level, pith-free citrus, a food-grade enzyme called pectinase can dissolve the pith without damaging the fruit segments.

  • Segment: Peel and separate the mandarin into individual segments.
  • Soak: Add the segments to a bowl with water and a small amount of powdered pectinase. The amount needed will vary depending on the product, so always follow the manufacturer's instructions.
  • Wait: Allow the segments to soak for a few hours. The enzyme will break down the pectin in the pith, causing it to become mushy and dissolve.
  • Rinse: After the time has passed, gently rub the segments and rinse them thoroughly to wash away the softened pith.

Comparison of Mandarin Pith Removal Methods

Feature Quick Scraping Warm Water & Scrub Boiling Water Method Pectic Enzyme
Time Required Very Fast Fast Moderate Long (requires soaking)
Equipment Spoon or fingernail Bowl, brush Pot, stove Bowl, pectinase
End Result Good, but can be uneven Very good, effective for most pith Excellent, very clean segments Professional-grade perfection
Scale Best for single fruits Good for a few fruits Good for a few to a batch Best for batch preparation
Pith Removal Manual, may miss some spots Manual, very thorough Heat-assisted, generally thorough Chemical-assisted, dissolves all pith
Fruit Integrity High High Good, with careful timing High
Flavor Impact None None None None (after rinsing)

Conclusion: Your Pith-Free Mandarin Awaits

Removing the white pith from mandarin oranges can transform a standard snack into a perfectly smooth and sweet culinary treat. Whether you opt for the quick manual scrape or the more advanced pectinase method, the right technique depends on your needs. For everyday enjoyment, the warm water or scraping techniques are perfect, while the boiling water method offers a fast track to cleaner segments for multiple fruits. For the absolute best, pith-free result, the enzyme method is unbeatable, though it requires more time. Don't let the pith stand in the way of a delicious mandarin; choose the method that works best for you and enjoy the pure, unadulterated flavor of the fruit.

Yes, the white stuff, or pith, is completely safe to eat and is actually quite healthy. It is rich in fiber, antioxidants, and flavonoids.

What is the white stuff on mandarins called?

The white, spongy material on mandarin oranges is called pith, also known as albedo. The stringy bits are also part of the pith.

Why is the pith on my mandarin so bitter?

The pith naturally contains compounds that contribute to its slightly bitter flavor profile. The level of bitterness can vary between individual fruits.

Does boiling the mandarin affect its flavor?

Boiling the mandarin for a very short period (less than 10 seconds) is not long enough to affect the internal flavor of the fruit. It only works to loosen the peel and pith.

Can I use a pectic enzyme if I don't have a specialized product?

For most home cooks, the simpler methods like warm water or boiling are sufficient. Pectinase is a specialized product typically used for large-scale canning or professional cooking.

How can I make the pith come off easier when peeling by hand?

One simple trick is to roll the mandarin on a hard surface with a little pressure before peeling. This can help loosen the skin and pith from the fruit.

What can I do with the removed pith?

While most people discard the pith, it can be used for culinary purposes. The pith is high in pectin and can be used to make jams and marmalades, where its bitterness is balanced by sugar.

Can I use this technique on other citrus fruits?

Yes, these methods can be adapted for other citrus fruits like navel oranges or tangerines, though the time and scrubbing required may vary depending on the thickness of the pith.
