The newly released Cognitive Cooking with Chef Watson includes 65 recipes, developed with the help of
what's billed as"the world#s first cognitive cooking system, "is the result of a three-year collaboration between IBM Research and chefs at the Institute of culinary education (ICE).
Starting out as a food truck, it went on to become an app, and on Tuesday it became a published"author."
"IBM says that Cognitive Cooking is not only a compendium of recipes, but also discusses the evolution of Chef Watson.
The dishes were produced by Watson's ability to extract facts from millions of pages of literature and draw relationships between them.
This allows it to produce a database of recipes, dish types, cooking styles, human psychology,
and from that, create new dishes. Central to this is the ability of the system to deal with food pairings.
This is an offshoot of the chemistry of taste as discovered by molecular gastronomy. Instead of dealing with dishes at an ingredient level
Watson looks at the actual chemicals that control taste and how one food pairs with another.
For example, a main taste chemical of tomatoes is shared with strawberries, so it's entirely possible to make bruschetta with strawberries.
By analyzing these pairings, Chef Watson came up with things like plum pancetta cider. Other recipes include Spanish Almond crescent, Creole Shrimp-Lamb Dumplings, Italian-Pumpkin Cheesecake,
and Hoof-and-Honey Ale. According to IBM, what works with food also works with other things, like creating new pharmaceuticals and cancer-fighting proteins.

#Douxmatok develops new technology that makes sugar twice as sweet, so you eat half as much A new technology in the food industry makes ordinary sugar twice as sweeto food tastes exactly the same with half the calories,
and without the controversy of artificial sweeteners. By coating tiny food safe particles with natural sugar like sucrose or glucose, the technology can trick the sweetness receptors on your tongue into thinking youe eating a full serving.
The startup behind the idea compares it to drug delivery in pharmaceuticals. rug delivery allows you to take less of an active material
But you still use sugar. Depending on the food, the technology cuts sugar by 25%to 55%.
%That means it also cheaper than a normal recipe. f the coated particle were the same sweetness as sugar,
it would be more expensive, obviously, he says. ut what we sell is sweetness equivalence.
If I twice as sweet as sugar you need only half as much in order to have the same sweet effect.
The sugar-carrying particle is already a commonly used food additive, so it doesn require new safety testing.
Theye developed a version that can be used in things like candy or cake and another that could cut back sugar in soda,

#Scientists Create LEDS From Food, Beverage Waste Most Christmas lights, DVD players, televisions and flashlights have one thing in common:
Two University of Utah researchers have now found a way to create LEDS from food and beverage waste.
In addition to utilizing food and beverage waste that would otherwise decompose and be of no use,
and Professor Michael Free, over the past year and a half, have turned successfully food waste such as discarded pieces of tortilla into CDS,
the researchers used soft drinks and pieces of bread and tortilla. The food and beverage waste were placed each in a solvent and heated both directly and indirectly for anywhere from 30 to 90 minutes.
After successfully finding traces of CDS from the synthesis, Sarswat and Free proceeded to illuminate the CDS to monitor their formation and color.
The ability to create QDS in the form of CDS from food and beverage waste would eliminate the need for concern over toxic waste,
as the food and beverages themselves are not toxic. Ds derived from food and beverage waste are not based on common toxic elements such as cadmium and selenium,
which makes their processing and disposal more environmentally friendly than it is for most other QDS.
the use of food and beverage waste as the starting material for QDS allows for reduced waste
cadmium selenide is also expensivene website listed a price of $529 for 25 ml of the compound. ith food
According to a report from the US Department of agriculture, roughly 31 percent of food produced in 2014 was not available for human consumption.

Recently, planetary scientists detected hydrated salts on these slopes at Hale crater, corroborating their original hypothesis that the streaks are formed indeed by liquid water.
we also found spectral evidence for hydrated salts on the slopes where RSL form.""Hydrated salts precipitate from liquid water,

According to Popular Science, the salt in the water allows it to remain liquid at lower temperatures.
