How long will juice made with a juicer be good?

Q. I make my juice every morning before leaving the house. However, clean up always has to wait until I get home, and the noise bugs my wife and kids @ 5:45 in the morning. I would like to know, generally, how long fresh juice is good for.

A. probably a couple of days maximum... The reason store bought juice lasts is because of the pasteurization process...

I would say a max of 2 days in a nice cold fridge in an airtight container... but nothing longer than that


Can orange juice and vitamins help cure a productive cough?
Q. I drink lots of orange juice (with Calcium and Vitamin D) and take a vitamin every day, and I have this productive cough. Can these help me get rid of it?

Note: I do not take any OTC medicines, nor do I want to take them anyway.

A. Vitamins are good to take and orange juice is good for you, but there are no real cures for your cough(if it is from viral infection). A productive cough is not necessarily a bad thing in the short term. If it persists for more than a week go see a doc. An expectorant won't do anything for you if it is already productive. That is used to make a dry unproductive cough more watery and productive. If you are annoyed by coughing spells and can't relax the best thing to do is take a cough syrup, but you don't take those. Drink plenty of fluids to keep the cough productive, it should pass. If it doesn't or you start getting any chest pains gp see a doc.

when lemon juice is added at the beginning of cooking lentils why does it slow the cooking?
Q. why does lemon juice slow the cooking of lentils when added at the beginning? does altering the pH effect the way lentils cook on a molecular level?

A. Boiling points are largely determined by intermolecular (hydrogen bonding and hydrophobic/hydrophilic) interactions. These three functional groups all contain an electron donor (oxygen or nitrogen) with a different willingness to share its electrons and thus a different capacity to hold on to other molecules. The tighter these interactions are, the higher the boiling point will be. The citric acid in Lemon Juice, a weak carboxylic acid, decomposes below boiling point at 175°C while water boils at 100°C.

**NOTE: If you're using a small amount of lemon juice, then it probably is not really effecting the boiling point**
