Il peut également s'agir de poudre de café à partir de café torréfié à sec, donc sans ajout de sucre pour le caraméliser.

lyophilisé ? As freeze-dried coffee is a marginal improvement on powdered coffee, it is generally kept as easily recognisabe granules, rather than being ground to powder. For the purposes of a patent, it would be important to be accurate about whether or not this coffee was in powder or granule form (whatever marketing people might say, I believe that dried coffee is amorphous, not crystaline). Coffee powder is dehydrated and it contains oil. There isn't enough oil in it to prevent it from being a powder.

I still use 20-year old instant coffee jars as kitchen storage jars. That was the best thing about instant coffee, though it could be useful for cake-making.

Ça pourrait bien être "sec" car: - optionally, pasteurizing the oil-in-water emulsion;
- optionally, drying the oil-in-water emulsion;
Je ne vois pas l'emploi de déshydrater pour un système qui contient de l'huile, en tout cas pas dans un contexte de brevet

fwiw/hth Instant coffee, also called soluble coffee, coffee crystals, and coffee powder, is a beverage derived from brewed coffee beans that enables people to quickly prepare hot coffee by adding hot water to the powder or crystals and stirring. Instant coffee is commercially prepared by either freeze-drying or spray drying, after which it can be rehydrated. Instant coffee in a concentrated liquid form is also manufactured.

Ça pourrait être du café lyophilisé effectivement mais comme c'est un brevet et qu'ils écrivent "dry" et pas "liophilised" je suis obligé de rester dans le vague
