Embodiment Construction

[0019] The invention provides a pressure transmission medium for ultra-high pressure sterilization, which is composed of a disinfectant and a solvent. The weight percentage of the disinfectant in the pressure transmission medium is 0.01% to 10.0%, and the balance is solvent.

[0020] Further, the disinfectant is selected from any one or combination of sodium hypochlorite, or bleaching powder, or peracetic acid, or hydrogen peroxide.

[0021] Further, the disinfectant is selected from sodium hypochlorite, and the weight percentage of the sodium hypochlorite in the pressure transmission medium is 0.1%-1%.

[0022] Further, the disinfectant is selected from bleaching powder, and the weight percentage of the bleaching powder in the pressure transmission medium is 0.01%-0.08%.

[0023] Further, the disinfectant is selected from peracetic acid, and the weight percentage of the peracetic acid in the pressure transmission medium is 0.1%-1.0%.

[0024] Further, the disinfectant is sel...

Abstract

The invention provides a pressure transmission medium for ultrahigh pressure sterilization, consisting of disinfectant and dissolvent, wherein the disinfectant accounts for 0.01-10.0 percent in the pressure transmission medium in percentage by weight, and the dissolvent accounts for the balance. Water is adopted to replace dioctyl sebacate to be used as a matrix of the pressure transmission medium for ultrahigh pressure sterilization, thereby effectively reducing the material cost. Simultaneously, water is nonflammable liquid, is free from potential fire-safety hazards and does not need to be especially stored. Metal ions, such as copper, iron, and the like can be gotten rid off by processing the medium with water through RO and ion exchange treatment, and the inner wall of an ultrahigh pressure vessel can not be corroded; and besides, fungi is initially eliminated, thereby avoiding cross contamination. By adding the disinfectant to the treated water, the fungi and pathogenic bacteria in the pressure transmission medium can be effectively killed, thereby avoiding potential microbial contamination. Components used by the medium are completely common additives for food production and can be prepared whenever needed, and circulating fund and inventory do not need to be used.

Description

Technical field: [0001] The invention relates to the field of chemical industry, in particular to a pressure transmission medium, in particular to a pressure transmission medium for ultra-high pressure sterilization. Background technique: [0002] In the prior art, the medium used for transmitting pressure in the ultra-high pressure sterilization container is dioctyl sebacate, which has the following defects: [0003] 1. Dioctyl sebacate is insoluble in water. After ultra-high pressure sterilization, the surface of the product is greasy, which does not meet the requirements of product quality standards. It is necessary to increase the cleaning process, increase the cost of labor and detergent and other materials; prolong the processing time, and cannot ensure the quality of the process. Requirements for the entire cold chain in terms of storage and transportation; after ultra-high pressure treatment, the light yellow liquid of dioctyl sebacate entrained in the product that c...
