The sprinkling of water makes you perceive products as fresh.
In order to make vegetables and products seem fresh on a shop shelf, Denmark came up with the idea to install small automatic dispensers in the stalls. Small drops look like dew and our brain perceives this as a sign of a product’s freshness. Many shops today use manual sprayers for this purpose.
One thing I'd disagree with, especially having worked in farming and selling at farmers markets: spraying produce with water keeps it from drying out. I keep lettuce in a bowl of water like a houseplant, and it stays fresh, solid, and crisp for a month, if somehow I have not eaten it. For the same reason, I drop other veggies in a bowl of water for a few hours before using them. Very often, we think veggies are spoiled, when in fact they're just dehydrated. Amazing sometimes how quickly and thoroughly they come back to life.
As a very seasoned shopper, I know I'm more fair in stating that what you've said doesn't always apply. Frankly? That's unfair information to hand down to our younger members, and I refuse to allow you to proclaim your "facts", when in fact? Different produce and foods preservations depend on their climate and methods.
Lettuce, celery,broccoli, cauliflower, and kale react very well if dehydrated and placed in a cold water bath for an hour. Carrots, tomatoes, potatoes, onions, cucumbers, all melons, and any fragile berries? No.
As a VERY well seasoned shopper and farmer, spraying water lends to the decay and molding of all vegetables depending on the temperatures at which they're stored after harvest.
ANY person reading this comment? DO NOT WASH YOUR VEGETABLES OR FRUITS UNTIL YOU'RE READY TO EAT THEM. Washing after picking adds extra moisture to the product and then they're stuffed in a package which invites mold and decay. Lastly? Organic isn't best. Be wise about your local grocer. Most importantly? ALWAYS, WASH YOUR PRODUCE IN FRESH WATER BEFORE EATING!
