AI Technical Summary

Technical Problem

Existing methods of preserving fruits and vegetables cause pathogenic bacteria to become resistant to antibiotics, causing harm to human health and the environment. They are also costly and difficult to promote on a large scale.

Method used

It uses Lactobacillus delbrueckii (CGMCC No. 11247 strain) to produce bacteriocins after activation, which inhibits mesophilic aerobic bacteria, yeasts and molds on the surface of fruits and vegetables. It improves the preservation effect of fruits and vegetables through soaking and drying, and through biodegradation and It is harmless to the human body for digestion.

Benefits of technology

Significantly extend the freshness time of fruits and vegetables, improve the preservation effect, avoid pathogenic bacteria resistance and health hazards, and reduce costs.

Abstract

The embodiment of the invention discloses application of lactobacillus delbrueckii. The application is characterized in that the lactobacillus delbrueckii is applied to inhibition of mesophilic aerobic bacteria, saccharomycetes, mould and coliform bacteria. The lactobacillus delbrueckii has a preservation number of CGMCC No.11247. In the lactobacillus delbrueckii activating process, bacteriocin can be generated and can remarkably inhibit the mesophilic aerobic bacteria, saccharomycetes, mould and coliform bacteria on the surfaces of fruits and vegetables, so that the preservation effect of thefruits and vegetables can be improved. Furthermore, secondary metabolites of the lactobacillus delbrueckii can be biodegraded and digested by human bodies, and are healthy and harmless to human bodies.
