Embodiment Construction

[0010] Specific embodiments of the present invention are:

[0011] 1. Set up the sterilization treatment room

[0012] The sterilization treatment chamber is composed of two parallel disc electrodes and a double electric potentiometer. A cooling jacket is installed between the two electrodes, and the electrodes are isolated from the concentrated turbid juice by an ion-conducting membrane. The ion-conducting membrane can be made of polyethylene sulfonic acid It is made of ester, acrylic acid copolymer or fluorinated hydrocarbon, and forms electrical conduction between the electrode and the ion-conducting membrane through the electrolyte. When the electrolyte solution circulates, the electrolysis product is removed at any time, and a new electrolyte solution is replaced when the electrolyte concentration changes;

[0013] 2. Set up juice temporary storage tank, vacuum pump and cooling device

[0014] Juice temporary storage tanks, vacuum pumps and cooling devices are respective...

Abstract

The invention discloses concentrated cloudy apple juice, which is a popular novel fruit juice product at present. The prior sterilization method causes serious damages to the heat sensitive substances in the concentrated apple juice and great loss of nutrients. The invention discloses a method for sterilizing the concentrated cloudy apple juice by using high voltage pulse electric fields and adopts a technical proposal comprising: building a sterilization room; arranging a temporary juice tank; a vacuum pump and a cooling device; arranging a high voltage pulse generator; setting working parameters; controlling sterilization temperature; concentrating and sterilizing cloudy juice; and detecting microbiological indexes. The method can kill harmful microorganisms in the concentrated cloudy apple juice effectively, reduce the survival rate of the harmful microorganisms to almost zero, and better protect the nutrients, color, scent and taste of the concentrated cloudy apple juice obviously than pasteurization. The sterilized concentrated cloudy juice meets national standards completely.

Description

technical field [0001] The invention relates to a method for sterilizing concentrated apple turbid juice, in particular to a method for rapidly and low-heat sterilizing concentrated apple turbid juice by using a high-voltage pulse electric field. It belongs to the technical field of food engineering. Background technique [0002] Concentrated cloudy apple juice is a new type of concentrated apple juice product that is popular in the market. It is more and more popular because of its high content of vitamins and trace elements, rich nutrients, full taste, soft and natural flavor, etc. favor. At present, the traditional sterilization method of concentrated apple juice is thermal sterilization, that is, using steam to raise the temperature of the concentrated juice to about 100°C, thereby killing various harmful microorganisms in it. This sterilizing method has obvious disadvantages. It will cause great damage to some heat-sensitive substances in the concentrated juice, and w...
