Clarified Citrus: Centrifuge Process

STEP 1: Juice

Clarification: Step 1

Pick the best fruit you can find. When clarified, the quality of the fruit is magnified — if there are any faults, it’ll come through.

STEP 2: Measure

If you don’t have a gram scale, get one. Use it for everything. Actually, get two: one utility scale (I like the Escali A115s) and a fine gram scale able to measure 1/100th of a gram (modernistpantry.com for the win, again).  Measure the final juice weight using the big scale, write it down.

STEP 3: Add Enzymes

This is where things get different depending on what type of citrus you’re spinning. For low-acid citrus, use the following method.

Grapefruits & Oranges (or similar): you’ll need Pectinex Ultra-SPL

  • Using your recorded juice weight from Step 2, calculate 0.2% of that weight. For example, if you have 1000 grams of Orange Juice, the number you’re looking for is 2 (1000 x 0.002 = 2). This will be the amount of Pectinex needed.
  • Add 2 grams of Pectinex Ultra-SPL to the juice (as calculated above)
  • Allow to sit for 15 minutes.

For high-acid citrus, the process is a bit more complex. Be patient, it’s worth it.

Limes & Lemons: you’ll need Pectinex Ultra-SPL, Chitosan, and Kieselsol 

  • Using your recorded juice weight from Step 2, calculate 0.2% of that weight. For example, if you have 1000 grams of Orange Juice, the number you’re looking for is 2 (1000 x 0.002 = 2). This will be the amount of Pectinex Ultra-SPL, Chitosan, and Kieselsol added to the juice.
  • First Step: add 2 grams of Pectinex and 2 grams of Kieselsol. Stir. Cover and allow to sit for 15 minutes
  • Second Step: add 2 grams of Chitosan. Stir. Cover and allow to sit for 15 minutes.
  • Third Step: add 2 more grams of Kieselsol. Stir.
  • Ready to move onto the next…

STEP 4: Decant Juice Into Equal Weights

Seems simple, but you can’t mess this part up. A centrifuge requires perfect balance on all sides of the rotor, so make sure all of the bottles you decant into are equal weights. Very important!

STEP 5: Spin Juice In Centrifuge

The sexiest step. Place the jars in the centrifuge, run at 4500 rpm for 10 minutes.

STEP 6: Strain

Remove jars from centrifuge, strain through a Superbag. If you’re the curious type, try the sludge at the bottom.

Clarified Orange Juice: Pretty, huh?
