Provided are surprisingly effective methods for producing uniform, cold-brew beverages (e.g., coffee, tea, fruit juice/extract, vegetable juice/extract, etc.) having an extended shelf-life, comprising: use of non-oxygen gas mixtures comprising hydrogen (to reduce or eliminate total packaged oxygen (TPO)), use of pressure/vacuum ports in brewing and/or conditioning chambers to provide chambered vacuum and/or pressure to enhance oxygen elimination, use of continuous mixing/agitation during the final conditioning phase to provide for even particulate suspension, use of a two-phase filtration system to provide for uniform tailoring of the amount and/or size of undissolved solids, and use of jacketed brewing and/or conditioning chambers for enhanced control of temperature, extraction uniformity and conditioning. Cold-brew beverages prepared by the methods, and systems for making same are provided. Beverages prepared by any method and packaged in a container and exposed therein to a non-oxygen gas mixture comprising hydrogen, and methods for making same are provided.

A method designed to clarify the coffee oil contained in coffee grounds or in whole and/or damaged coffee beans. Said objective is achieved by way of a method that starts with inoculation of the coffee grounds or coffee beans with macromycetes, especially with white rot fungi, continuing with an incubation step that allows complete population of the coffee grounds or coffee beans by the fungal mycelium to be achieved, and finishing with steps of drying and extracting the coffee oil. The method disclosed allows colourless or pale yellow coffee oil to be produced, favouring the use thereof in cosmetic and food products, amongst others.

A coffee degassing method is disclosed. A diffusion gas is supplied into a degassing tree in an bin containing roasted coffee. The degassing tree is in the roasted coffee. Carbon dioxide is diffused from the coffee with the diffusion gas. Carbon dioxide and the diffusion gas are exhausted from the bin. Another method of coffee degassing is disclosed. A diffusion gas is supplied into a degassing chamber in a bin containing roasted coffee. The degassing chamber is in the roasted coffee. Carbon dioxide is diffused from the coffee with the diffusion gas. Carbon dioxide and the nitrogen are exhausted from the bin.

The invention relates to methods of reducing acrylamide during high temperature cooking of carbohydrate-containing foods, in particular vegetables or tubers which are deep fried. In particular, the invention relates to a method of reducing acrylamide during cooking of a carbohydrate-containing food, said method comprising at least the following steps: contacting said food with a first hydroxy acid selected from lactic, malic and tartaric acids at a pH less than or equal to its pK.sub.a, or its lowest pK.sub.a; part-cooking said food at a temperature at which the Maillard reaction occurs whereby to form a part-cooked food;optionally packaging and/or storing said part-cooked food; contacting said part-cooked food with a second α-hydroxy acid selected from lactic, malic and tartaric acids at a pH less than or equal to its pK.sub.a, or its lowest pK.sub.a; and subsequently further cooking said food at a temperature at which the Maillard reaction occurs.

A coffee degassing device is disclosed and method. The coffee degassing device comprises a coffee bin and a hollow tree within the bin. The hollow tree has an opening in communication with the interior of the coffee bin. The tree provides an exit path for carbon dioxide off-gassing from the coffee. The device may have a diffusion gas supply conduit. The diffusion gas supply conduit is in communication with the hollow tree and is configured to supply nitrogen, or another diffusion gas, to the degassing tree for accelerating the degassing of coffee.
