Green in the interior, red in the interior and in the F minor scale
Ami Ben Best
In 1894, when he was close to 60 years old, he ate Mark Twain for the first time
In his lifetime a watermelon. The enthusiasm of the American writer was so great until
He wrote: "Eating watermelon is a pleasure that has no competitors. when a person tastes
From this fruit he knows what the angels eat." Spectrum who loves you
The exaggeration, reminds that the origin of this fruit of the angels is probably in the region
ours, and watermelons in their current form were already known in ancient Egypt
Nearly 5,000 years ago. The Jewish connection to watermelon begins
Exodus from Egypt. When the Israelites walk in the desert and they don't have enough
food, they miss those good old days in Egypt: "We remembered
The fish and the zucchini and the watermelons and the hay and the onions and
The Shumim and now our souls are dry.." (Bamadbar XNUMX).
Today you can find this fruit from the pumpkin family almost everywhere
on earth The leading country in the world in watermelons is China, there
About 18 million tons of watermelon were grown last year. Lovers in Israel too
Love this wonderful fruit. According to data from the Vegetable Council, in
98 reached the local market about 164,000 tons of watermelons, when the consumption
The main one is of course in the hot months, June-July, around
50,000 tons per month.
The technology itself, looks, how to say, a little strange. the main component
In the system it is a surface with spongy rubber on which the watermelon is placed. Another component here
A metal arm to which a small wooden hammer is attached. A small press on the metal trigger
Brings the hammer down on the watermelon. A tiny microphone picks up the sound
The punch and transmits it via an electrical signal to a laptop that converts it
for digital information. A dull click of a watermelon due to an acoustic signal generator
which appears on the screen as a fading climax. After a series of
Experiments with watermelons of different sizes, it turns out that frequencies between 100 and 250
Hertz represent watermelons with sugar levels between 8 and 12 percent,
which is the right anthem. The testing process, according to the developers, lasts 12 seconds
only and good vulnerabilities.
But this number, says Spectrum, is still not perfect. A classic problem
Related to watermelon is the question of early identification: how to identify a sweet watermelon,
No early opening. Over the years, various techniques have been developed in this regard
But not one of them guarantees a hundred percent correct choice. There are these
The recommenders examine the stem and see if it is withered and not completely dry.
Others recommend sliding their fingertips over the watermelon in order to feel whether
There are tiny protrusions of tendons that indicate ripeness. But the method
The most popular is still the tapping method. According to a popular method
And this time immemorial, the skilled watermelon testers tap a rind
The watermelon and identify, or at least try to identify, what their relationship is hiding.
This non-invasive vocal technology is reaching the peak of popularity
Its at the beginning of the summer which is also the beginning of the season, when you can see a crowd then
Taps standing in the stalls of the vegetable shops and bastas and listening to the sounds
the watermelon
But even in this field, it turns out, there are developments. Just these days she announced
The University of Delaware in the USA for the development of innovative technology
To test the ripeness of the watermelon without outside intervention. The development is exciting
petition among the American breeders, and spokesman for the American National Association
The watermelons even announced that the new device may save the growers a huge fortune.
It often happens to us, he explained in a special message to the media, that trucks
Large ones loaded with watermelons, returned to us, after they were found
In a random check some white watermelons.
