The present invention discloses an ultrasound-electrode-nano-porous membrane coupling hydrogen production and sterilization system, which comprises a vessel and a plurality of hydrogen production units arranged in the vessel. The hydrogen production unit comprises a cavity, and a broadband ultrasonic generator and a circular hydrogen production electrode located in the cavity. The circular hydrogen production electrode wraps around the broadband ultrasonic generator. A bottom membrane at the bottom of the cavity is hydrophobic at the inner side and hydrophilic at the outer side, and a side membrane of the cavity is hydrophilic at the inner side and hydrophobic at the outer side and is mounted vertically or obliquely upwards by an angle of 0-45 degrees. The system has the functions of continuously and efficiently facilitating self-circulation micro-flow of a liquid system, hydrogen dissolution (as nano-bubbles), conversion from the interface to the bulk phase and dispersion of bubbles, sterilization and others. The hydrogen content in a prepared anti-bacterial functional beverage is high (3-6 ppm), wherein the diameter of hydrogen-rich nano-bubbles is distributed within the range of 20-1000 nm, and the nano-bubbles are retained for 8-36 hrs or more even in an unsealed state. The means of preparation of the present invention is simple, intelligent and efficient, the product is high in quality and green and has a health care function, waste of a lot of filled hydrogen and high-pressure energy consumption are avoided, secondary pollution of the system is prevented in processing, and food-grade requirements are met.

A product including a bottle with a mouth; a drink inside the bottle, the drink including a version of an alcoholic drink, where there is no alcohol or there is alcohol at a concentration by volume less than 1.5%; a pourer attached to the mouth and having a flow channel, a check valve, an air-vent channel and a filter, where the flow channel and the check valve allow via the same a flow of the non-alcoholic drink towards outside the product, the air-vent channel allows air to pass inside the bottle, and the filter produces a filtration of the air passing inside the bottle via the air-vent channel, the drink being any of a non-alcoholic drink, an alcohol substitute drink, a low alcohol drink, an alcohol free drink, or a de-alcoholized drink. Also, a method for extending the lifetime of a non-alcoholic drink, related to making the drink.

A heat-sterilized packaged beverage containing ascorbic acid in an amount of 6 mg/100 ml or more and having a ratio of the amount of ascorbic acid to the amount of a medium-chain fatty acid triglyceride (ascorbic acid/medium-chain fatty acid triglyceride) of 0.0003-0.1340 inclusive, to which 1 mg/100 ml or more of catechins (the total amount of catechin, catechin gallate, epicatechin, epicatechin gallate, galocatechin, galocatechin gallate, epigalocatechin and epigalocatechingalate) are added. Thus, an unpleasant smell like deteriorated rice bran, said smell being generated during the storage of the heat-sterilized packaged beverage that contains ascorbic acid and the medium-chain fatty acid triglyceride within the range as specified above, is reduced.
