I’m foam averse. It’s a texture thing. Don’t like smoothies, yogurt, or pulp in my orange juice either. But I love the fresh juice, as long as I skim off the foam and discard it or strain it off first. Am I discarding the nutrients and therefore wasting my time juicing? You said no question is silly!
Good question, thank you for asking.
When juicing, your juicer may produce a certain amount of foam in the juice. The amount of the foam/froth depends on the type of juicer you use, and what you’re juicing. Masticating juicers (slow juicers) would produce less foam compared to centrifugal juicers (high-speed spinning). And fibrous fruits/vegetables would produce more foam compared to the less fibrous counterparts.
When a juicer or blender spins at high-speed, it captures more air that mixes with the juice, causing the juice to be “fluffed” and “frothy”.
Like you, I would often scoop out and discard the foam/froth produced when juicing before drinking. For two reasons:
- The foam/froth is mostly oxidized as it is the product of a mixture of minerals and “trapped” air bubbles. Oxidation is a result from the “dark side” of oxygen which may harm our cells in the long run.
- The foam/froth are air bubbles. Consuming them will mean consuming extra “gas” into our gastro, causing bloating and burping.
So you’re doing right by discarding the foam. You can also use a strainer to sieve out the foam and pulp if you like your juice to be smooth.
The above are just my reasons/opinion. There might be more reason(s) for or against drinking the foam with the juice, but I don’t believe you lose any nutrients by discarding.
Hope this explains!
