A method for cold-brewing a non-acidic coffee product may include adding minerals to water, creating mineralized water; brewing an alkaline coffee product using the mineralized water; and removing coffee grounds from the alkaline coffee product. The brewing step may be a cold-brewing step including soaking coffee in the mineralized water for a desired period of time, such as from about 8 to about 24 hours. The minerals may be carbonate compounds or any other compound capable of raising the pH level of the water to be greater than 7 prior to brewing. The resulting product may be a non-acidic coffee product.

The present invention relates to coffee beverage compositions comprising soluble coffee solids and particles of roast coffee beans and with reduced formation of scum and a low content diterpenes. The invention further relates to methods of producing such coffee beverage compositions by removal of oil from a slurry of particles of roast coffee beans.

Disclosed is a process for the production of aromatized soluble coffee particles. The process comprises the incubation of an aroma donor, such as a roasted coffee, with a acceptor, such as a refined coffee oil. The acceptor can be added prior or after incubation to the soluble coffee particles. The disclosure of the present technology also pertains to a process for the preparation of an instant coffee product comprising aromatized soluble coffee particles. Thereby an odor-acceptable edible oil is subjected to aroma transfer from roast coffee beans, either before or after being applied on soluble coffee particles. The aroma transfer being conducted for an incubation time of at least one day, and the amount of the aromatized oil in the instant coffee is 0.8 wt. % to 4.5 wt. %.

Provided herein is a method for extraction of crude coffee oil (CCO) from spent coffee ground (SCG) using Mechanical Hydraulic Press Machine. The extraction includes a preliminary step of reducing moisture content of the raw material followed by mechanical extraction of the spent coffee ground to obtain crude coffee oil. Also provided herein is a chemical-free method for purification of crude coffee oil to obtain pure coffee oil.

The present invention relates to a liquid coffee beverage in a closed container with improved aroma having a high ration of high volatile coffee aroma compounds to low volatile coffee aroma compounds in the gaseous headspace, and a method of producing

A process for the microfluidic extraction of molecules of interest from a vegetable oil, which utilizes a microfluidic chip with a double-Y-channel circuit, two inlets, two outlets, and a main channel, a first vessel including vegetable oil and a second vessel including ethanol for extraction, a pressure controller for pressurizing the vegetable oil and the ethanol, a first collector for the triglycerides-enriched vegetable oil and a second collector for molecules of interest-enriched ethanol. The extraction process includes: controlling the pressures to subject each of the vegetable oil and the ethanol to a pressure, so the interface between the two fluids is positioned at the junction point of inlets, bringing the vegetable oil and ethanol into contact with each other in the main channel for a time to enable extraction of the molecules of interest, collecting the molecules of interest-enriched ethanol, optionally, evaporating the ethanol, collecting the triglycerides-enriched vegetable oil.

Disclosed herein is a process of extracting coffee oil from a coffee-based feedstock by using an extraction solvent, where a mixture of the coffee-based feedstock and the extraction solvent is kept under mechanical or magnetic agitation for at least 30 minutes, and subsequently, a liquid phase including the extraction solvent is separated and the extraction solvent is removed from the liquid phase, to obtain the coffee oil. The extraction solvent can be an ester solvent. Also disclosed herein is a coffee oil obtained by the aforementioned process.
