Problems solved by technology

[0003] In general, the existing sterilization methods generally include high temperature, high pressure, chlorine-containing bactericides and other physical and chemical sterilization methods for killing bacteria, but physical methods such as high temperature, high pressure methods and chemical methods such as chlorine Adding other chemical substances will destroy the flavor and taste of the food to a certain extent, and also destroy some elements in the food that are beneficial to the human body, such as minerals, vitamins, some proteins and amino acids, etc.
[0004] What is more serious is the killing of some items that are more harmful and difficult to kill in infant and child food, such as killing Bacillus sakazakii. If traditional methods are used to either increase the dose of fungicides or add other chemical fungicides, there will be food Security risks
Either increase the intensity of physical sterilization, which will increase the difficulty of changing the flavor of food

Embodiment 1

[0042] The milk is disinfected, and the bacteria mixed in the milk are effectively disinfected by a catalytic reaction; the catalysts used are bio-enzyme bactericides such as antimicrobial peptides, lysozyme and lysostaphin; the antimicrobial peptides, lysozyme and lysostaphin and other biological enzyme bactericides to make slow-release microcapsules or tablets, install the slow-release microcapsules in the grid 3, milk flows through the device, and the bacteria mixed in the milk will come into contact with The enzymes released from the lysozyme, lysostaphin and antimicrobial peptide sustained-release capsules produce a catalytic reaction that occurs instantaneously. The antimicrobial peptide, lysozyme and lysostaphin directly crack the bacterial cell wall to kill the bacteria. Harmless amino acids.

Embodiment 2

[0049] Drinking water is treated, and the method and device that adopt are identical with embodiment 1.

[0050] In this embodiment, when the biocide is directly sprayed into the reactor through the nozzle 7, the antimicrobial peptide is used as the disinfectant, and the concentration coefficient of the antimicrobial peptide is controlled at 0.5%-2%.

Embodiment 3

[0052] Beer is processed, and the method and device that adopt are identical with embodiment 1.

[0053] In this embodiment, when the biocide is directly sprayed into the reactor through the nozzle 7, the antimicrobial peptide is used as the disinfectant, and the concentration coefficient of the antimicrobial peptide is controlled at 0.8%-5%.

Abstract

The invention relates to a liquid food sterilizing and disinfecting method. Bacteria in a liquid food are instantly killed by adopting a catalytic reaction; a catalyst adopted in the invention is a biological bactericide, the biological bactericide is one of or a combination of an antibacterial peptide, lysozyme and lysostaphin, the temperature in the use process of the antibacterial peptide is controlled to be -80 - 120DEG C, and the pH value is 4-9; and the temperature in the use process of the lysozyme and lysostaphin is controlled to be 2-50DEG C, and the pH value is controlled to be 5-7. The invention also provides a liquid food sterilizing and disinfecting apparatus. The liquid food sterilizing and disinfecting apparatus adopts a reactor, the reactor is a tubular reactor or a barrel reactor, and a grid or a nozzle is arranged in the reactor. The method and the apparatus have the advantages of concise structure, high convenience and practicality, and realization of continuous and effective sterilization and disinfection of liquid foods.

Description

technical field [0001] The invention relates to a method and device for sterilization and disinfection of liquid food using antimicrobial peptide and biological enzyme technology, which can be applied to sterilization and disinfection of dairy product production lines, drinking water production lines, fruit juice production lines and other liquid food. Background technique [0002] With the improvement of people's living standards in our country, the requirements for food safety are getting higher and higher, the intensity of food safety supervision is further strengthened, and higher requirements are put forward for the sterilization and disinfection of liquid food. Pasteurization or ultra-high temperature disinfection is usually used for the disinfection of raw milk; liquid chlorine, chlorine dioxide, ozone and ultraviolet disinfection are usually used for the disinfection of drinking water; Sterilization, UV sterilizer, etc. [0003] In general, the existing sterilizatio...
