Low foam production: The foam that accumulates on top of your juice is a good indicator of how much air has been whipped into your juice by the machine, and more air exposure equals more oxidation. Oxidation is a controversial topic. As Harold McGee explains in On Food and Cooking: The Science and Lore of the Kitchen, “Because juicing mixes together the contents of living cells, including active enzymes and various reactive and oxygen-sensitive substances, fresh juices are unstable and change rapidly.” So the prevailing theory among juicers is that if less oxygen is whipped into a juice, the valuable nutrients and enzymes remain more intact. But as Kohler told us, there’s not much peer-reviewed research on how or if oxidation affects the nutrient contents of your juice. “It’s all manufacturers’ data for the most part,” he said, “which I take with a grain of salt.” That said, we still prioritized machines that produced less foam, because at the very least, oxidation can cause your green juice to turn brown, and may lead to some muddy, off flavors.
Celery will juice just fine, but for greens I use one of those slow juicers, the vertical version. The celery, raspberry, strawberry and things like kiwi come out better on slow juicers. It appears that “one size fits all” idea is only good for T-shirts, so considering one can get slow masticating juicers for much less then they used to cost there is no reason not to have one as well, so you can make nectar out of spinach and celery – it does taste weird but it is quite nutrition.
If you’re a serious juicer who needs to cut down on prep time but doesn’t want to cut down on the quality of your juice, the SKG New Generation Wide Chute Juicer might be your perfect match. The feed tube is 3 inches wide which means that you don’t have to always chop up your produce for juicing. The low 60rpm speed ensures you get a high juice yield, minimum amount of pulp, no heat build up, and no foaming.
This machine does come with a 1000 mL pitcher, which means it could hold roughly three 12-ounce sodas. Fresh juice does not keep for long, so you typically wouldn’t make lots of it in advance; however, if you are making juice for your family or for the next day or two, it is nice not to have to stop and empty the pulp. You can get through a lot of produce before you need to pause.
The two most popular types of juicers are centrifugal juicers and masticating juicers. These different types of juicers utilize very different approaches in how they grind up fruits and vegetables. Both have advantages and disadvantages distinct to their design, and both have groups that feel one particular type of juicer is the best juicer. Before you proceed much further in looking for the best juicer possible, you should strongly consider your own personal juicing needs. For example, if you’re only ever going to be juicing lemons and oranges, you’ll likely be best served by buying a citrus juicer. If, on the other hand, you plan on juicing loads of Organic Wheat Grass, you’ll likely be best served by focusing your search on masticating juicers.
The VSJ843 makes almost-pulp-free juices, certainly the smoothest juice I’ve ever produced in a home kitchen. And it has a high yield, too. It made slightly less carrot-apple juice than the Tribest, yielding 15.15 ounces, putting it near the middle of the pack among machines we tested in 2015. But it had the second highest green juice yields of any juicer we tested, producing 12 ounces of kale-apple juice.

Equipped with a 1000-watt powerful motor, this easy-to-use juice extractor makes it exceptionally convenient to enjoy fresh, healthy fruit and vegetable juice from the comfort of home. The unit's large 3-inch feeding chute can accommodate whole apples, pears, and other large-size fruits and vegetables (extra-large items may need to be cut into smaller pieces first).
And the Tribest Slowstar doesn’t just juice. It also comes with a “homogenizing” mincer attachment that grinds without extracting liquid—useful for making sorbets, nut butters, and more. I haven’t used the machine for anything other than making juice, so I can’t attest to its food-chopping and frozen-fruit-sorbet-making abilities, but you can see it in action in this DiscountJuicers.com video. The separate bowl attachment fits onto the base, using the auger to pulverize the food and push it through a large chute without a screen.

Hamilton Beach is a reputable brand that offers quality appliances at affordable prices. And its 67650A Juice Extractor is no exception. This extremely affordable centrifugal juicer is easy to assemble and use, even for beginners. The stainless steel micromesh strainer basket ensures that the pulp gets separated from the juice. And the extra wide feed chute enables you to cut down on your chopping time.
