Embodiment Construction

[0014] To meet food hygiene requirements as a benchmark, non-limiting examples are described as follows:

[0015] 1. Juice: Take orange juice as an example, fill the orange juice with 0.5-3 times the packaging volume of CO 2 , Sterilized at 100-500MPa, holding time ≤ 15min.

[0016] 2. Alcohol: Take beer as an example, fill with 1 to 4 times the packaging volume of CO 2 , Sterilized at 100-500MPa, holding time ≤ 12min.

[0017] 3. Dairy: take fruit milk as an example, fill it with 0.05 to 3 times the packaging volume of N 2 , Sterilized at 100-500MPa, holding time ≤ 20min.

[0018] 4. Mineral water: filled with 0.5-4 times the packaging volume of sterile air, the pressure is 200-500MPa, and the holding time is ≤10min.

[0019] 5. Industrial water: Fill it with sterile air 1 to 5 times the packaging volume, sterilize at a pressure of 100 to 500 MPa, and keep the pressure for ≤ 8 minutes.

Abstract

The present invention relates to a gas synergistic superhigh pressure sterilization method of liquid substance. It is characterized by introducing gas into the liquid substance, then making sterilization at 100-1000 MPa. The described gas can be selected from aseptic air, nitrogen gas, CO2 or inert gas. Said method is applicable to sterilization of beverage, milk, wine, drinking water, industrialwater, biological preparation and low-concentration solvent.

Description

1. Technical field [0001] The invention relates to a sterilizing method, in particular to a sterilizing method for a liquid substance, to be precise, a gas-assisted ultra-high pressure sterilizing method for a liquid substance. 2. Background technology [0002] Sterilization is a common unit process in the biological, food, beverage, and pharmaceutical industries. Heat sterilization often causes denaturation and odor. Ultra-high pressure sterilization usually uses a pressure of 600-1000MPa to carry out normal temperature sterilization. Ultra-high pressure sterilization can avoid thermal denaturation of the processed object and maintain the original flavor of the material to the greatest extent. Therefore, ultra-high pressure sterilization technology is known as "the most practical cutting-edge technology in the 21st century". [0003] Although ultra-high pressure sterilization has significant advantages, it must solve the problems of high pressure and continuity in order ...
