Embodiment Construction

[0011] Non-limiting examples are described as follows:

[0012] 1. Fruit and vegetable juice: Taking orange juice as an example, the first step is continuous dynamic sterilization with ultra-high pressure process pump at ultra-high pressure 100-400MPa; the second step is sterilization with static ultra-high pressure at 100-600MPa, and the holding time is ≤15min .

[0013] 2. Mineral water: The first step is to use an ultra-high pressure process pump to continuously and dynamically sterilize at an ultra-high pressure of 100-300 MPa; the second step is to use a static ultra-high pressure to sterilize at a temperature of 100-500 MPa, and the holding time is ≤ 10 minutes.

Abstract

The invention relates to a two-step ultrahigh-pressure sterilization method of liquid matter, which is a two-step method combining both a dynamic processing and a static processing. The two-step ultrahigh-pressure sterilization method is characterized by comprising the following steps of: (1) dynamically and continuously processing the liquid matter at the pressure of 100-400 MPa; and (2) statically processing the liquid matter at the pressure of 100-600 MPa. The two-step sterilization process is carried out at 80 DEG C. The sterilization method can reduce the pressure of static ultrahigh-pressure sterilization to below 600 MPa, simultaneously ensures the killing effect on pressure-resistant bacteria and meets the requirements of food sanitation.

Description

1. Technical field [0001] The invention relates to a sterilization method, in particular to a liquid substance sterilization method, to be precise a two-step ultra-high pressure sterilization method for liquid substances. 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 can avoid the thermal denaturation of the processed object and maintain the original flavor of the material to the greatest extent; the so-called ultra-high pressure sterilization usually uses a pressure of about 600MPa to sterilize at room temperature; for pressure-resistant bacteria, such as Bacillus, even It is also difficult to achieve the killing effect even when the pressure reaches 1000MPa. [0003] Although ultra-high pressure sterilization has significant advantages, it is necessary to solve the problems of high pressure a...
