Juice does stay fresh for about 24-36 hours if it is kept in cold climate, the loss of the nutrients come with time. Juice is better consumed right after you make it because the more time you take to consume it the less nutrient value it will have. You should consume the juice right away to get the full value of your juice. But for your fellow co-workers they are probably consuming it more for taste and some nutrients, it is safe for them to drink within the recommended time.
Masticating juicers have the edge because of their low-RPM processing of juices. Hi RPM juicers start the oxidation process immediately, but that doesn't mean the juice is no good within minutes.
I juice for my wife and me in the morning around 6pm. I store our lunch juice in an airtight/vacuum, stainless steel thermos. This minimized the continued oxidation, and the juice if fine a lunch. If storage duration is of the utmost importance to you, then a masticating juicer is your best choice.
You should know that juicers have evolved significantly over the last few years. There's also a lack of scientific data to prove or disprove how "potent" masticating juicers are vs other juicers. Much of the opinion out there (like mine) is opinion and very unscientific.
If you plan to consume the juice within a few hours, and store it properly, centrifugal juicers are a viable option. Your research will show that each type of juicer has significant advantages and disadvantages.
The best juice from the supermarket is worst than juice produced from the cheapest juicer.
For anyone to suggest that Centrifugal juicers are poor juicers is simply false.
There is a comparison chart at the bottom of this page.
usually inexpensive centrifugal juicers (the sort available on the high street) merely grate fruits and vegetables, leaving strings of unbroken cells. The juice from the cells that have been broken is then spun out at very high speed (6,000 to 10,000 rpm). Because the juice is flung out, it mixes with the air and so oxidises (turns brown) quickly. The pulp usually remains very moist, because the process has not extracted all the juice. Not only is this more wasteful, but the juice is paler, more watery, lower in nutrient value and often quite insipid in flavour.
I'm just beginning to juice. I have an hour commute to work and would really love to be able to take some with me for during the day. What are your thoughts on freezing the juice? I have an idea of using ice cube trays to freeze quicker and then I would be able to mix certain flavors in one glass. What nutrients are you losing when you don't drink it right away? Also, instead of juicing kale I wanted to add kale powder to my other fresh juices... Or is that a bad idea. Lol clearly I'm a beginner but id really appreciate any feedback! Thanks
Are all nutrients being lost with time? Vitamins? Phytonutrients?
It is not just a problem with loosing nutrients. There is also the problem of oxidisation.

Listen carefully to the first 90 seconds of this:
Now, how do we know Brian is telling the truth? Think about it.... When you pick fruit off the tree or vegetables out of the ground, testing has shown they lose HUGE amounts of nutrition within the first hour (enzymes, phytonutrients, hormones and even vitamins). So how can something which has been juiced magically retain the nutrients??? IT CAN'T!!! lf a picked vegetable or fruit can't retain the nutrition, there is no hope that a juice can.
People are being deceived...but all people need to do is use their common sense and it is obvious what the real truth is.
Yes, even the Norwalk juice goes bad in 15 minutes. That's way l have always said to drink it within the first 5 minutes at the very latest. Do the juicing session in small amounts and numerous sessions: juice half a cup and drink it, then juice another half a cup and drink it....that's the only way it can be done.
I know that what you are saying is the ideal but we can not always have the ideal and will just have to do the best that we can.
