What's the most important factor when choosing a juicer? For some, it's ease of use. For others, it's speed. Clear juice also consistently ranks as one of the most important factors when juicing. Juice clarity is determined by the amount of pulp in the juice, foaming, and oxidation. Let's take a look at some ways to minimize foaming.
The higher the rpm of the juicer, the more air is mixed into the juice. This is what creates foam.
Some juicers include a strainer which fits on top of the juice container. For example, the Sana 707 includes a large glass juice bowl with a custom fit stainless steel strainer. This will filter out all the foam.
If your juicer doesn't include a strainer, you can always pour the juice through a large hand-held strainer when pouring it into a glass. A smaller strainer can be used to scoop out much of the foam without losing too much juice.
Apples sometimes can make a lot of foam, and sometimes not. It depends on the variety of apple, and the type of juicer.

Single auger juicers have the lowest amount of foam from pineapples. Both centrifugal juicers and twin gear juicers create very significant amounts of foam with pineapple. A strainer is essential, as sometimes there can be a ratio of two parts foam to one part juice! With an Angel juicer, it is very helpful to use the optional pusher with the silicon seal ring, as otherwise the foam will travel up the feeding tube and can be messy.

There's no getting around it: spinach creates the most foam of any commonly-juiced fruit or vegetable. Regardless of the juicer, there will be significant foaming. A coarse strainer can be very useful to separate the foam from the juice.

Centrifugals are not recommended for any leafy greens, as the result is almost always a very large amount of foamy pulp with minimal juice extraction.
