data about the rate of nutrient decay in fruit/vegetable juice [closed]

This is a related question to Do centrifugal juicers destroy vitamins through friction?

Is there any quantitative data about the rate of vitamin & nutrient decay in fruit/vegetable juice?

We just bought a centrifugal juicer, and I want to make an educated decision about whether to use the juicer as needed (maximizing nutrient content but increasing cleanup effort) or to produce fruit/vegetable juice 6/12/18 hrs ahead of time (reducing cleanup effort but perhaps reducing nutrient content).

I decided to look into this question out of personal curiosity and here is what I found:

Some nutrients will naturally decay over time - mainly due to oxidation, but also on their own. The lifespan of most vitamins I looked up was at least a few days, so if you are making your juice ~18 hours ahead of time I doubt you'll lose much (if any) nutritional value.

According to this article: http://www.ultimatecitrus.com/vitaminc.html

When fresh citrus is stored at 38°F for 12 weeks, there was no loss of vitamin C, but when stored at high temperatures, the loss was great.

Vitamin A, B6, K also last for a very long time before decaying. Only a few have a low half-life, eg. B3 with a half-life of 20-45 mins, but your body can produce that on its own.

Based on that, it doesn't seem like you have anything to lose by making the juice in advance and storing it. If you were leaving the juice to sit in the fridge for weeks at a time then I'd say you might lose a tiny bit of nutrients (also the juice would go bad :-P).

A good tip is to minimize the exposure to oxygen by using either a sealable container or a jug with a lid that closes, and keep your juice in the fridge and the loss of nutrients is sure to be minimal even after the length of time that you plan to store it for.

How quickly do vegetables lose their nutrients?

Most produce loses 30 percent of nutrients three days after harvest.

How quickly does fresh juice lose nutrients?

Drink Your It Within 72 Hours (3 Days) Again, fresh juice loses nutrients quickly (which is why store-bought juices have even less nutritional value). That's why nutritionists recommend you drink your fresh juice within 24 to 48 hours or, at most, 72 hours.

Do vegetables lose nutrients when juiced?

Studies show that people who put their favorite fruits and vegetables in a juicing machine actually lose nutrients in the process. Juice extracted from fruits and vegetables will contain vitamins, minerals and other plant nutrients. But when you \u201cjuice\u201d some of the healthy fiber is lost.

How does juicing affect the nutritional content of the fruits vegetables involved?

Juicing extracts the juice from fresh fruits or vegetables. The liquid contains most of the vitamins, minerals and plant chemicals (phytonutrients) found in the fruit. However, whole fruits and vegetables also have healthy fiber, which is lost during most juicing.
