Truffle

Mix, it appears, wanted nothing less than a signature drink. When you ve got more stars than a movie, you don t rest on how many cosmopolitans you sell, I m guessing. The restaurant s bar, which employed Thierry Hernandez, and now Xavier Herit, from the Hotel Plaza Adienee in Paris, tried a truffle martini—truffle juice sprayed onto die glass in place of vermouth, with orange vodka. For an idea so potent, it was a nondescript drink. The truffles used were... 

Chinese, not French, and inferior, and the cocktail was more power of suggestion than sensation—a dimly dirty-tasting snore. (If you try this at home, use French or Italian truffles and garnish with a slice of truffle, not a lemon twist, as Mix did. You ll hit real pay dirt instead, in both senses of the words.)...

Fantozzi et al. [73] presents the study of the carbon footprint of a typical food product in Central Italy truffle sauce. This is a mixture of vegetable oil and truffle in proportions of 33% and 67% respectively and minor components and spices (garlic, salt, pepper, etc.). Both truffles and olives are cultivated and harvested in a farm in Umbria (Italy). Olives are crushed in a mill that is situated few kilometers from the farm. Once it has been produced, the extra virgin oil, together with the truffle, is transported to another facility to produce bottled truffle sauce. The carbon footprint calculation is based on ISO 14076 technical standard. Product Category Rules (PCR) have been developed (see Table 7).

This is a clear example of a cradle-to-grave study, so GHG fluxes comprise also disposal of the packaging. The consumption phase is not considered in the study. The functional unit is 1 kg of truffle sauce. 

Results of the analysis are proposed in Table 8. Cultivation gives an important contribution to the final impact of truffle sauce, while truffle production has a reduced impact, because it is a very extensive production. Olive trees cultivation uses fertilizers, diesel fuel for field operations, electricity for the olives harvest, herbicides and pesticides.

Chemical signals associated with egg sites are probably widespread in insects, but we know much less about them than about sex attractants. These egg-site signals guide one of a female insect s critical decisions, her choice of appropriate places to lay her eggs. If larvae are to have a chance to survive, they must hatch into a suitable setting where proper nourishment is available. Not all larvae are as particular about their food as those of French truffle flies (,Suillia humilis and related species), which feed selectively on the...

For all of recorded history mankind has located and identified certain items by their aroma. Whether it is a dead mouse in the closet or a freshly baking loaf of bread in the oven, we often make the identification correctly without seeing or touching the item. We have considered this sense so useful that when we find our own sense of smell to have inadequate sensitivity for a certain task we often borrow the more acute sense of smell from some animal. For centuries we have used dogs for hunting and pigs for truffle harvesting. 

Virtually all people lack the ability to detect some specific odors. A striking example of such an anosmia is the inability to smell the volatile steroid androsten-one (5a-androst-16-en-3-one), a constituent of perspiration, of some pork products, truffles, and celery.922...
