Do espresso beans expire?
The espresso coffee bean is from roasted from the arabica species that contains 60% fat soluble lipids responsible for the essential coffee aromatic oil. The aroma of the espresso bean on shelf preservation undergoes a slow chemical change like all coffees. Oxidation occurs and the bean/grounds will stale.

Why do grocery store owners spray their fresh vegetables with water?
The reason they do this is because of the plant's turgor pressure, which is the pressure of the cell's contents against its cell wall, determined by the water content from omosis. If there is more solute in the plant than in its surrounding environment than you have a hypotonic solution where water diffuses into the cell to achieve equilibrium. Thus by routinely spraying the vegetables with water it keeps up their turgor pressure and keeps them nice and crisp for us to eat.
Asked in Coffee, Food Storage and Preservation
Does coffee expire?
Yes, it goes bad. Coffee is a time sensitive product that will oxidize and go stale. Several things will accelerate the process. Direct light, heat, refrigeration and air to name a few. Keep your coffee sealed in an airtight container, and in a dark, cool place. -- There are ways to age coffee. It's becoming more popular among the gourmet set. About.com has a good guide on aged coffee. http://coffeetea.about.com/od/advancedcoffee/fl/Aging-Coffee.htm
Asked in Cheeses, Food Storage and Preservation, Feta
How do you make brine for feta cheese?
Store in brine: Feta is traditionally sold in a brine solution (heavily salted water). It can be refrigerated, covered with the brine, for a long time. As the amount of brine decreases, add more. To make brine you mix one pound of kosher salt with 1 gallon of water. The salt may not dissolve completely; that is normal. If the feta is too salty, take the piece you want to use and soak it in a mixture of 1/2 water and 1/2 fresh milk for an hour. also you can alter the flavor of the feta by adding milk with the brine. I usually do this to make the feta smoother and creamier. But I worry about the milk spoiling so after about a week I change the mixture. I also replace the brine mixture every 4-6 weeks. Most Greeks don't, but I worry about contamination.

What is fish salting?
From the Preparedness Blog Network: How To Salt Fish. I recently came across a cookbook from the 1850s. That cookbook is very interesting covering all types of pioneer cooking. One of the articles covers the preserving of shad, a type of fresh water fish. The recipe used for shad can be used for any fish. The following recipe is taken directly from the cookbook. "Clean the shad nicely, place them in layers with back down, and laid open so as the inside of the fish may be up. Sprinkle each fish plentifully with ground salt, and let them stand twenty four hours. This draws out all the blood. Wipe them all dry with clean napkins. Place them in layers in a clean tub, with the backs down as before. For one hundred shad take half a lb. saltpetre, and 2 pounds of brown sugar. Strew plenty of rock salt over them with the saltpetre and sugar, there is no danger of putting on too much salt as they will only absorb a certain quantity." As you can see, this is a very simple recipe. You will notice this recipe uses quite a bit of salt, I strongly recommend that everybody store at least 100 pounds of salt, if you intend to do any food preserving. Saltpeter or saltpetre is commonly known as potassium nitrate.

How do you get the Titanium Dioxide Out of M and M's?
I kinda made this question, then answered it... Because I thought that it would be beneficial to those whom it may concern. Anyway: Get roughly 20 M&M's, any color, but make sure that they are the normal ones. EG: Not the "Crunchy" ones or the "Peanut" ones. Place the m&ms into a container. Then pour water into it, until the M&M's are submerged, and wait until all of the color and white stuff has come off. Give the container a good swirl to speed it up. Then take the m&m's out - eat them if you want, they taste fine - then put the remaining liquid into a nice untouched place that won't get knocked or bumped. Over 1-2 days, all the titanium dioxide will sink to the bottom. Then pour out the liquid on top. Add in some more water, swirl it around and pour that out too.(We're trying to get out all of the impurities)Add in some more water, just a few drops, and, Using a paint brush wipe down the bottom of the container. And there you have it, titanium dioxide, mixed with water, but it is still titanium dioxide. You can then go and make a solar panel from this If you want to make a solar panel then just search up "Titanium Dioxide Solar Panel"
How long will cat food stay good without refrigeration?
If it is wet cat food, then it will last for around three hours at the most, although personally wet cat food should not really be left out that long. Dry food can be left out most of the day, but even this can become stale if left out too long. It is always best to throw away old kibble and replace with fresh every day.

Does coffee stay fresher in the refrigerator?
No. When you chill coffee you condense the moisture in the air in the bag, and draw the condensation out of the beans/grounds. As you warm the beans/grounds they will not reabsorb all the moisture. The flavor will stale, and when subjected to hot water the acid and oils will be released in concentration giving the coffee an overdone flavor.
