Application of bdellovibrio mixture as bactericide to cleaning of fruits

Abstract

The invention discloses application of a bdellovibrio mixture as a bactericide to cleaning of fruits. The application is characterized by comprising the following steps of: adding the mixture bacterium fluid of bdellovibrio plastids and swimmers of bdellovibrio serving as the bactericide into water for cleaning, and cleaning the fruits; or spraying the mixture bacterium fluid of the bdellovibrio in fruit processing environment and cleaning the processing environment, wherein the bdellovibrio is Bdellovibrio sp. BDM01, is called CCTCC for short, and was collected in China Center for Type Culture Collection on April 28th, 2008 with the collection number of CCTCC NO: M208066. The mixed bacteria serving as the bactericide is utilized to clean the fruits, and 95 percent of pathogenic bacteria on the surface of the fruits can be killed. And the mixed bacteria have the advantages that: the swimmers have quick response and high activity, the bdellovibrio plastids are easy to prepare and store, the sterilization action time is longer and the environmental tolerance is higher.

Description

technical field [0001] The invention relates to the application of the Bdellovibrio mixture, in particular to the application of eliminating pathogenic bacteria carried on the fruit surface and its processing environment. Background technique [0002] Fruits contain rich nutrients necessary for human survival. Although eating vegetables can replace fruits to a large extent, they cannot be completely replaced, because the nutritional content of fruits is not the same as that of vegetables. Therefore, the consumption of fruits is very important for the comprehensive intake of human nutrition. Regular consumption of various fruits is one of the important means to ensure good nutrition and material balance in the body. [0003] With the continuous improvement of people's living standards, the consumption of fruit is no longer satisfied with the original eating method, and the quantity and quality of deep-processed fruit products, such as juice, jam, fruit wine and preserves, a...

Problems solved by technology

[0005] At present, the industrial cleaning process of fruits is mainly carried out by the combination of physical cleaning and chemical fungicides. First, different cleaning equipment is selected according to different types of fruits, such as DT5A1 cleaning machine, blast cleaning machine, XGJ-2 type The main principle of the washing machine is the friction and interaction between the fruit and the washing water. At the same time, it is assisted by the brush roller to clean the dirt on the fruit surface; secondly, choose a suitable cleaning agent. There are many types of cleaning agents on the market. For washing, decontamination, and sterilizing functions, although the traditional cleaning method is good for removing soil from fruits and vegetables, it has no obvious effect on microorganism removal

Most of the currently used fruit fungicides are chlorine-based fungicides, but these can not only kill microorganisms such as Escherichia coli, Salmonella, Listeria monocytogenes, Staphylococcus aureus, etc. on the surface of fruits, but also interact with certain ingredients in food The reaction produces chloride, which is harmful to the human body. The cleaned wastewater contains chloroform formed by the reaction of chlorine residues and organic matter in the water, which not only pollutes the water body and the atmosphere, but also causes cancer to the human body.
