Product Description

Omega J8004 Nutrition Center Single-Gear Low Speed Masticating Juicer, White

The Omega J8004 Nutrition Center is a masticating style juicer. Sometimes referred to as a low speed juicer, the Nutrition Center processes at 80rpm, whereas most other juicers process at a speed of 1,650 to 15,000rpm. The low speed protects and maintains healthy enzymes, prevents oxidation and allows juice to be stored up to 72 hours without degradation. The GE Ultem Auger is 8x stronger than most other plastics and the powerful gear reduction is equivalent to a 2HP Motor. The dual stage juice processing system extracts the maximum amount of juice from fruits, vegetables, leafy greens, even wheatgrass! You can also use the nutrition center to turn nuts into nut butters (an all-natural peanut butter), make baby food from natural, fresh ingredients, whip up soy milk, extrude pasta, grind coffee and spices, and mince herbs and garlic. Make delicious and nutritious drinks and snacks that everyone will love. Measuring 7in wide, 15.5in deep and 8.5in tall.

5.0 out of 5 stars Identical to the J8006, better than the J8005, and a most cost-effective juicer for greens June 22, 2010

By Aaron702

Amazon Verified Purchase

UPDATE: As of March 11, 2013, the J8006 (identical, but with a chrome look), was temporarily $209 on Amazon (sold by Amazon, itself). This had always been a more expensive color. Please be sure to compare and buy strictly on price between these two models. Enjoy!

My wife and I have had this for two months of intense juicing of cabbage and occasionally broccoli. My wife had multiple stomach and duodenal ulcers from medications due to a spinal injury and we combed the internet looking for studies on the best home remedies, as prescription antacids were not healing her. We chanced across two studies on raw cabbage juice healing ulcers in a matter of weeks, so that led me to research juicers.

There are four basic types of juicers. In order of general effectiveness (least effective to most effective) on greens, they are as follows:

1. Spinning blade/centrifugal ($50-$200)
2. Single-gear masticating (like this one) ($200-$350)
3. Double-gear masticating ($425-$550)
4. Hydraulic press w/shredder ($1,000-$2,500)

We were hoping the ulcers would heal quickly and I didn't plan to invest much. In reading the reviews on the spinning blade-type extractors, they seemed a poor choice for leafy greens, but quite good for fruits and other types of vegetables. One additional caveat I found was that juice from such juicers didn't keep that long, apparently due to oxidation and heat friction. My wife grew up with such a juicer and she had always enjoyed it, but she agreed it wouldn't work well for wringing juice from a cabbage.

Next came the single-gear juicers, and these varied from steel to melamine construction to a new high-tech super-hard GE plastic.... Steel can oxidize fruit juice and melamine is a soft plastic that is most known for appearing in contaminated animal food from China, which in tests artificially appears as protein. Neither of these sounded good, but in reviewing the latest versions of the J8006/J8004 (they are identical except for the color and $40 difference), I found Omega was using GE Ultem, a plastic at least six times harder than melamine for the augur. This was a huge plus to me.

The double-gear juicers appear to get about 15% more juice out of the same amount of produce, but take quite a bit more time to clean. They are also twice the cost of single-gear juicers. This wasn't worth it to me.

Finally, the hydraulic press juicers get the most juice out, but can cost thousands of dollars. I couldn't find one under $800.

Our Experience:

I decided to get the J8004 and we went to town using it. It's been used probably 40 times so far for about 45 - 60 minutes each time. I make two quarts of cabbage juice at a time and it's refrigerated, with my wife drinking all of it within two days. At the end of the second day, if it's been kept sealed in the refrigerator, the juice tastes virtually identical to when it was juiced (just shake it up a bit because the juice settles).

Directions for the juicer say it shouldn't be used more than 30 minutes at a time. This isn't a problem, as I prepare two plates of cabbage leaves, juice them, turn off the machine, then prepare two more plates of leaves at a time.

The Omega leaves some juice in the pulp, which I now recapture by feeding the mash back through the machine. Strangely, the extra passes go very fast compared with the first one with the leaves, basically because the mash goes in the tube with absolutely no friction, and is much less volume to handle. In general, if you are juicing cabbage leaves, this is how each pass juices out if you got 600 milliliters with the first two platefuls:

1st time - 600 milliliters
2nd time - 150 ml more
3rd time - 50 ml more
4&5th time - 50 ml more total

Yes, the double-gear machines might get more each pass, but I figure that putting cabbage through three times is more than equal to putting the it through twice on a double-gear, and I save $250 for that net of one extra pass.

The unit has held up well and has never stained from all the greens touching it, so save forty dollars and get this over the silver J8006 twin (both units are superior to the J8005 because that unit, strangely numbered higher than this, uses a melamine auger and has only a 10 year warranty). The parts all rinse clean in no time, save for the two filtering portions on the cone the augur presses against. These require a brushing motion (one is included) to clean, and even then the part with the fine mesh retains some cabbage fiber. Fortunately, we put the parts in the dishwasher where anything remaining can be blasted off.

We've used it to mass-grind coffee with an included grinding option. It grinds a pound of coffee in about three minutes.

You can't go wrong with an Omega J8004 if you are juicing greens. We would definitely buy this again, but due to the incredibly long warranty, we don't expect to buy anything for over 15 years!

UPDATE: We've now used it more than 60 days on cabbage and broccoli and used it to make wonderful blueberry sorbet (using the second cone unit for grinding). Putting frozen wild blueberries into it makes a sorbet come out the end that if allowed to thaw, is a perfect cold blueberry juice. This summer we have been using it in this capacity far more than for cabbage. WONDERFUL! (NOTE: My wife's ulcers completely healed by the two month point, so we've moved on to juicing other items.)

5.0 out of 5 stars The Great Masticator: Omega 8004/8006 perfect for lazy first-time juicers like me November 22, 2010

By J. Kim VINE™ VOICE

Length: 3:59 Mins

Video review for the Omega 8004 (white version of the 8006) masticating juicer

Likes: Base has a compact 11"x8" footprint, 15-year warranty, quiet operation, ease of juice (har har), 30-second clean-up, efficient, produces a dry pulp, juice is low-foam and fantastic, multi-functional - can be used with included attachments to make nut butters, grind coffee, mince produce, and extrude pasta.

Dislikes: A little slow, narrow 1.5" feed tube, soft/juicy items like cucumbers and citrus fruits need to be pushed down to prevent jamming.

Green juice recipe in the video (sorry I presented some items out-of-frame, I'm a first-time videographer too), produces about 2 cups of juice in 5-6 minutes:

3 stalks celery
6 large romaine leaves
Big handful spinach (2 oz)
Small bunch of fresh herbs (parsley, basil, cilantro, mint, or a mixture)
1 small (2") peeled lemon, with pith, halved lengthwise
2 small (3") green apples, cored and cut into eighths
1/2 large English cucumber, quartered lengthwise
1/2-inch piece of peeled ginger

Tips: Alternate hard fruits and veggies (apple, celery) with soft (lemon, cucumber) when pushing down the tube. Best to end with a hard veggie like celery or carrot to "clean-out" the auger. I place the filter directly on top of the juice collection basket (the smaller one, closest to the base), even though the manual tells you not to use it during the juicing process.

To clean, I disassemble and soak the parts in a bowl of hot water (the prep bowl works nicely if you're using one) while I drink or bottle the juice; then give the parts a quick rinse and air dry on the dishwasher rack.

5.0 out of 5 stars An Awesome Juicer & Great Investment February 25, 2010

By T. Young

Amazon Verified Purchase

This is my first juicer and I am thrilled I made the right choice. I researched for about a month before I got my tax return and pulled the trigger, and it has turned out to be a great investment in my health. The machine is extremely durable as it has a full 15 year warranty. This is exactly the same model as the Omega J8006 that everyone loves so much (according to reviews) with the only difference being that it's white. A cosmetic difference but I'd rather keep the 40 bucks and be a little less fancy personally. Works great with everything I've thrown at it so far from wheatgrass to celery to carrots, apples, yams, pears, kiwis, zucchini, ginger, you name it. The only exception and this was an early mistake I made after I first got it and that is you don't want to juice bananas. Too mushy and just makes a mess. Extremely easy to take apart and clean though so within 5 minutes it was clean and ready to go again. Pulp comes out very dry so it is very efficient as well. All in all I think this model is probably hard to beat. Seems like it will last forever. Super easy to clean. What more could you want? 5 stars easy

5.0 out of 5 stars Why it's the Best Value Juicer on the Market!!! June 17, 2012

By Albert J. Valentino

This review is coming from someone with nearly 20 years of juicing experience that has realized tangible benefits long ago and am sold on the need to juice. However, in that time I used a centrifugal Juicer, with my most recent one of 11 years being the Waring PJE401 Juice Extractor, Quite White and Stainless Steelwhich is still going strong, and juiced about 80% carrots and about 19% apples. I recently realized, after attending my mothers funeral, 92 1/2 years old, and pondered what else can I do to stay healthy unlike all my siblings, that what was truly deficient in my regiment was greens. The more I read, especially the book Super Immunity: The Essential Nutrition Guide for Boosting Your Body's Defenses to Live Longer, Stronger, and Disease Free, the more it was obvious that since I always hated eating them and since that was not going to change, I can just juice them. I then educated myself on every juicer on the market - learning the brands, watching endless youtube videos and juice-off comparisons, and of course following that up with reading numerous customer reviews. Investing in the right juicer is a big decision and it is cheaper to get right in the beginning. So this review will share what I learned and I hope this helps you make a decision.

First, know this, 1) the best juicer is the one you use regularly - if it is difficult or too time-consuming to use or clean or too be big to fit in a prominent place in your kitchen the honeymoon will be short.... 2) A cheap juicer will cost the most - because it is either inefficient with the yield, or it will break quickly, this is the lifespan of the juicer so calculate this investment in cost/year. A $69 juicer that lasts a year costs $69/yr. A $300 juicer with a 15 year warranty cost $20/year. The cadillac of home juicers is the Super Angel, $1000 and extracts 10 - 25% more juice than other juicers in the $200-$1000 range. How much will you juice helps to calculate how long a 20% higher produce bill for a $300 juicer will recoup your investment. If you juice only once in a while, the higher investment will never pay for itself. But, if you juice 2x day, or for several people, it could be within 3 years of so before the more expensive juicer actually pays for itself. That $69 juicer will likely yield 40-50% the of the Super Angel juicer, or perhaps a 25% for most other, so if you will be juicing a lot, that $69 juicer will cost the most. The above cost analysis was for all those people on the fence about price. My 11 year old $200 Waring, which is still working, cost me under $20 year, while my first $69 juicer, and my second, $99 juicer, never had their second anniversary.

What is does well: Leafy Greens, Wheatgrass, Celery, Carrots. Also, apples. Like almost all masticating juicers, soft fruits are not their thing, they do better in centrifugal juicers or smoothies. Centrifugal juicers just do not leafy greens well at all, period. Masticating juicers like this squeeze the life, I mean juice, out to the cells. These are the best way to get nutrients from greens since we are not cows with four stomachs designed to break down the cellulose walls to extract the nutrients, humans don't do this well so the need to chew their greens many, many times to break it down before swallowing. Few of us do that, we often ignore the parsley with comes with a meal, even though ounce for ounce it is the most nutritious thing on the plate. And the few times someone like me does put it in my mouth I chew lightly and swallow since it is not a pleasant taste. Leafy greens and wheatgrass do very well.

Cleanup:
Do not underestimate cleanup as a factor in your selection. Some juicers take in excess of 10 minutes to properly clean. Perhaps not a big deal if you make a large batch for two days but if you make a glass to drink fresh twice a day then cleanup time is serious consideration. Cleanup time on a juicer is mostly related to the size of the screen which needs to be cleaned right a way with a brush so else the holes get clogged and the process becomes less efficient. The Omega model has a short screen and only a few parts and once you master a workflow for cleanup is literally less than 2 minutes, probably the shortest time for any juicer on the market. A Greenstar Elite juicer, for $500 is a great double auger juicer, and cleanup is between 5 -10 minutes, closer to 10 minutes due tough to clean edges and the Super Angel takes less time.

Comparisons to Omega 8004/8006:

The Omega 8004/8006 models has the best warranty in the business, 15 years. The more expensive Omega Vert 350 is only 10 years.

Omega 8004 is white and the 8006 is chrome covered plastic for $40 more - (I actually purchased the 8004 and used the savings towards 40 pounds of inorganic carrots). That is the only difference!!!

Omega VRT350 Heavy Duty Dual-Stage Vertical Single Auger Low Speed Juicer costs about $379 and is seemingly faster to use and has bigger opening so cutting up to smaller sizes is slightly less work. However, it is known for stalling on carrots, clogging on stringy celery, and having plenty of pulp in the juice - see reviews. The Omega 8004/6 includes a pulp screen to fit over the juice bowl, the Vert does not. Compared to the Omega 8000 series, based on video juicer-offs, it has a lower yield and much higher foam for wheatgrass and greens like kale. Also, cleanup is about 2x longer so the faster feed may be compensated by the longer cleanup depending on how much you are juicing at one time.

Champion Juicer
Doesn't do wheatgrass or leafy greens well unless you buy a separate $75 attachment increasing the overall cost. Even with that, the yields are lower than the Omega and the net price would be more.

Centrifugal Juices:
These `noisy juicers' excel at speed/faster juice times and do soft fruits and things like carrots better in terms of quantity. But, since the blades wiz by so quickly they oxidize the juice - this is evidenced in the foam. As a result these juices have a shorter shelf life. Which is not a problem if you drink your juice right of way. But, that's not all, this can harm the enzymes. In my own juice-off for carrots with my Waring juicer, the Warning had a 3% higher yield, but the juice had over twice the foam and but more importantly the taste was noticeably more watery than the richer tasting masticated juice - yes, this was the same batch of carrots. So quality of juice is not as good, but total time is significantly less - lower quality is always better than anything you buy in the store so if you are in a rush each morning and only can make time to drop a whole apple and a handful of carrots down the shoot, get a centrifugal juicer. A better juicer that is not used is a useless juicer.

Double Auger models:
This is a single auger masticating juicer, and there are also double auger juicers and the two best models are the Green Star Elite Jumbo Twin Gear Juice Extractor (GSE-5000) and Super Angel All Stainless Steel Twin Gear Juicer- 5500. Double auger juicers feed leafy greens and wheatgrass in very well - they will literally pull them in between the two augers. This is great but with harder things like carrots, you will need to push down unlike a single auger which will go in easily and be broken-up during the initial feed. The Greenstar model will also produce a lower yield and more foam with wheatgrass and leafy greens but will do better in terms of yield with carrots, apples, celery and cucumbers. So the omega 8004/6 is better at just leafy greens but you will likely juice other things as well so the Greenstar will net a higher overall yield. The longer screens on these models add to the cleanup time. The Super Angel is by far the most efficient juicer for just about everything and cleanup to faster than the Greenstar. It costs 2x more, has a 10 year warranty, but the screen only has a 1 year warranty and costs $190 for a replacement - something to consider. The screen on the omega is covered for 15 years and if you step on it and break it, the replacement cost is only $26.

Norwalk Juicer:
This is the Rolls Royce of juicers and possibly the best juicer in the world and will juice anything that can be juiced via a two step process that first triturates (break apart) the produce and then presses out the juice in a hydraulic press. This is the juicer recommended for the Gerson diet since it has the best quality and quantity. It costs $2,500!!! Good choice for big families, especially if you want to save on baby food, but not as great if juicing for one - as I am.

Frozen Banana Berry Smoothies:
The Omega has attachments for pasta, baby food, spaghetti, and a blank screen. I have used the blank to make frozen banana and berry smoothies. These are great and better than ice cream. I personally add a few whole nuts and coffee beans so they get ground up to make a great treat with a caffeine buzz. Smoothest if you run it through twice.

Tips for use:
Invest in a good sharp knife. The extra cutting for the small 1 1/2" opening is only seconds if you have the right knife. I use the Victorinox 40570 Cutlery 6-Inch Chef's Knife, Black Fibrox Handle for all my needs.

Start and end with a carrot - if you are using carrots. All masticating juicers require some back-pressure at the end and the harder pulp of carrots is perfect - softer apples are less ideal. I also end with a carrot to push out any slush.

Wheatgrass: start with a carrot piece to built up pressure else lose a few precious drops and the initial squeeze, then run the wheatgrass through and grab the pulp and drop it in the hopper a second time for a second press - this will yield another 10-20%.

Alternate your produce as you juice, do a carrot, a few leafs, celery, then a carrot... Instead of doing all your carrots, then all the apples...

Don't force it too fast, push it in slowly, it's not a Breville.

Celery leafs are bitter, consider cutting them off before juicing

Clean immediately, I clean mine before I drink or finish my juice - easy since cleaning is very fast and easy with this design.

Greens are strong tasting and can have a fast and potent detox effect - headaches, runs to the bathroom. Start by make your dark greens about 25% by volume and have a base of something like celery, cucumber, carrots and apples. Carrots and apples help to sweeten the bitterness of some leafy greens like kale. Any headaches and sudden bowel movements will go away with time as you body detoxes and adjusts - those problems are the reason why you should juice, not why you shouldn't!!!

Apples, pears and lemons/limes can be mixed with vegetable juice. Other fruits should not be mixed - something to due with digestion efficiency, sweet vs alkaline.

Do not juice the skins of orange or grapefruit - they are slightly toxic. Lemons are okay

Juicing is great breakfast since `breakfast means to break the fast' of not eating during your nights sleep. With an empty stomach juice gets absorbed best without taxing your body.

I hope the above helps you see I think it is the best value juicer for most people. Decide your priorities and pick the one that is best. This is a long term investment in yourself, try not to be cheap and ideally buy from a place you can return if what you get is not for you. I love mine and use it twice a day.

Juicing is a simple way to get essential pro-life nutrient dense foods efficiently into your body - nutrients are already digested saving your body the work. Very important if you don't eat a lots of veggies, especially greens, like me. This is lifestyle choice to protect, prevent and heal your body so the best juicer for you will be the one you will use daily. This model is easy to use, and one the fastest and easiest to clean - under 2 minutes. Slower than centrifugal juicers but the quality takes time, especially with the dark greens. If you owned a million dollar race horse how would you feed it? An ounce of prevention is worth pounds of toxic medicine.

As a side note, in the past few months of using using this model, about twice day, with plenty of greens like wheatgrass (growing my own on my balcony), kale, collards, parsley...mixed with mostly carrots, and also apple and celery, my enlarged prostate problem as disappeared!!! So glad I made a move to a masticating juicer to get those well needed greens in my body. Read more ›
