57 results about "Coffee roasting" patented technology

Roasting coffee transforms the chemical and physical properties of green coffee beans into roasted coffee products. The roasting process is what produces the characteristic flavor of coffee by causing the green coffee beans to change in taste. Unroasted beans contain similar if not higher levels of acids, protein, sugars, and caffeine as those that have been roasted, but lack the taste of roasted coffee beans due to the Maillard and other chemical reactions that occur during roasting.

Coffee roasting control system and process

The inventive process comprises micro-processing means utilizing a coffee roaster control algorithm for controlling the roast process of coffee beans. The algorithm utilizes curve fitting techniques to calculate polynomial coefficients used in generating a smooth curve to control the coffee bean temperature during the roast process. Through the use of multiple set points and actual historical data, the polynomial coefficients are generated. The coefficients are then used to plot a graph that indicates the path the roast process will try and maintain.

Par-baked and milled coffee beans for use in foods, beverages and dietary supplements

The present invention concerns compositions and methods relating to the addition and use of par-baked and milled coffee beans in food products, beverages, and dietary supplements. Par-baked and milled coffee beans are a novel alternative to more costly chlorogenic acid extracts, and are edible and palatable as a food ingredient. The ingredient is prepared from the entire Coffea robusta or arabica green coffee bean and provides substantially increased amounts of dietary chlorogenic acid antioxidants compared to roasted beans. When the green coffee bean is appropriately par-baked at a temperature significantly lower than coffee roasting temperatures, the bean retains significant moisture, yet becomes embrittled, enabling milling to produce fine and beneficially hydrophilic particles, without any significant loss of bioactive chlorogenic acid and without significant pyrolysis occurring. As described herein, the par-baked coffee bean is superior to both the green coffee bean and the traditionally roasted coffee bean for adding chlorogenic acids to foods, beverages and dietary supplements.

Method and apparatus for preventing the discharge of powdery caffeine during coffee roasting

Coffee beans are roasted with heated air in a roasting chamber, and contaminant-laden exhaust air including caffeine entrained therein is discharged from the chamber. While roasting is in progress, the exhaust air from the chamber is heated, directed through a catalytic converter and cooled to a temperature between about 250° F. to 325° F. Thereafter the cooled exhaust air flows through a cooler or condenser where the temperature of the cooled exhaust air is further lowered to between about 100° F. and 155° F., and it is then directed through a HEPA filter to remove caffeine particles that are present in the cooled air. Substantially caffeine-free clean exhaust air can then be discharged from the HEPA filter directly to the surroundings of the roasting machine such as a closed room, e.g. a retail establishment, frequented by persons.
