A method of processing roasted coffee to improve the retention of carbon dioxide and aromatics liberated from the roasted coffee. The method involves preparing one or more containers for receiving coffee. The containers are purged of contained air through flushing with an inert gas. Roasted coffee is transported and delivered to a grinding circuit where it is ground directly into a container filling apparatus. The container filling filling apparatus delivers the ground coffee directly into the purged containers after which the containers are sealed to maximize the retention of carbon dioxide and aromatics liberated from the roasted coffee and to minimize contact of the ground roasted coffee with the air.

In one embodiment, the invention pertains to the treatment of either green and un-dried, or green and dried, coffee beans with enzymes in a pH adjusted environment. According to the subject invention, the enzymes to be used, the pH of the treatment medium, and the times of treatment are parameters that are optimized based on different desired flavor and/or aroma outcomes.

A ready-to-serve coffee product which provides a refreshing beverage or topping. The product is a black, coffee containing liquid in an aseptically filled container. The liquid has a fresh, clean taste and may contain more than 2% by weight of soluble coffee solids. The liquid is produced by extracting coffee solids from roast and ground coffee at a draw-off ratio of less than about 3. The concentration of soluble coffee solids in the coffee extract is then adjusted to less than about 5% by weight under oxygen-reduced conditions.

Heat-treated and ground coffee beans having savory flavor and aroma are achieved in a unique process described herein that combines all these different treatments in a single-stage operation.

An improved method for myceliating coffee includes providing raw coffee beans, preparing the raw beans for fungal myceliation by removing chlorogenic acids from the green coffee beans inoculating the prepared raw coffee beans with a fungal component to enable fungal myceliation of the green coffee beans. The method includes buffering the aqueous solution with a buffer selected from the group consisting of: sodium chloride, citric acid and ascorbic acid. In one embodiment, the method further includes myceliating the raw coffee beans under optimal conditions for mycelial growth, and preparing the myceliated coffee beans for roasting by washing the myceliated coffee beans to remove undesired metabolites produced by the fungal component. The myceliated coffee beans are roasted. Roasted coffee beans are then ground and brewed into a coffee beverage.

The invention provides a method of processing green coffee beans that improves the aromas and flavors of green coffee beans through simple means, allowing richly fragrant green coffee beans that have unique aromas to be obtained with ease. A method of processing green coffee beans includes a fermentation process by bringing green coffee beans, which are unground seeds from coffee berries, microorganisms, and nutritive substances that are metabolized by the microorganisms into contact with one another to cause fermentation, followed by a separation process of separating out only said green coffee beans that have passed through the fermentation process.

The present invention provides a method for the preparation of a myceliated coffee product. This method comprises providing green coffee beans and optionally heat treating the green coffee beans to provide prepared green coffee beans. Furthermore, a step of inoculating the prepared green coffee beans with a prepared fungal component and culturing the inoculum to prepare the myceliated coffee product is included. The present invention discusses different embodiments of the invention and the various products that can be developed by altering certain parameters, such as green coffee bean moisture content. The methods of the instant invention result in prepared green coffee beans and myceliated coffee products having reduced levels of undesirable taste components, such as 2-furanmethanol, and increased levels of fungal metabolites, such as β-glucans and other polysaccharides, relative to starting green coffee beans.

The invention relates to a preparing method of low-caffeine instant coffee. The preparing method includes the steps that raw coffee beans are soaked in water for 0.5-1.5 h; the soaked raw coffee beans are steamed for 0.5-1.5 h at the temperature of 90 DEG C-110 DEG C; the steamed coffee beans are dried until the water content is 10-15%; the dried coffee beans are baked for 10-20 min and ground until the fineness is 5-30 meshes; the ground coffee powder is prewet for 10-30 min with water accounting for 20-50% of the mass of the ground coffee powder and is extracted with water for 5-20 min at the extracting temperature of 170 DEG C-180 DEG C and the extracting pressure of 0.9-1.2 Mpa; extract liquor is concentrated to 45-55 Brix, and subjected to spray drying to obtain the low-caffeine instant coffee. The caffeine content of the baked coffee beans and the instant coffee product is obviously reduced while the flavor of the product is not reduced obviously.
