"METHOD OF EXTRACTION AND / OR PRESSURE OF FOOD OR FOOD DRINK". Food to be extracted and / or pressed is fed into a colloid mill or twin screw extruder and, immediately after grinding and / or simultaneously with grinding, a cold solvent (eg water or milk at - 3 <198> C to 50 <198> C) is added to it. After treating the food with the extruder, the cake is eliminated to produce an extract and / or a pressing juice. After grinding an objectified food (eg coffee, green tea, black tea, herbal tea, wild herbal tea, Chinese herb tea, cocoa, vanilla, fruit or vegetables, either as a single material or a combination thereof) ), an extract or a pressing juice can be obtained quickly and highly efficiently at a low temperature in a mode suitable for mass production without any taste deterioration due to oxidation after grinding, etc. Compared to existing extraction / pressing methods such as the cold extraction method with an extended time requirement, the above method is very advantageous from the points of view of improving taste and economy. In the case of tea drinks, for example, useful components are preserved and the vivid color shades characteristic of individual teas can be maintained for a long time. |
