Abstract

The invention belongs to an antistaling agent or preservative and especially relates to a bacteriostatic application of purslane. In the bacteriostatic application of purslane, purslane juice which is extracted under aseptic condition is used as an antistaling agent and/or a preservative to coat on the surface of fruits and vegetables, thus inhibiting the reproduction of bacteria breeding in fruits and vegetables; the dried purslane is grinded to powder and used as the antistaling agent and/or a preservative to be sprayed on the surface of fruits and vegetables, thus inhibiting the reproduction of bacteria breeding in fruits and vegetables; and fruits and vegetables are embedded in the purslane powder which is used as the antistaling agent and/or a preservative, thus inhibiting the reproduction of bacteria breeding in fruits and vegetables. The purslane juice and dry powder provided by the invention have inhibitory effect on bacillus, staphylococcus aureus and colibacillus which are related closely with the food contamination and the decay of fruits and vegetables, wherein the inhibitory effect is strongest on bacillus, the inhibitory effect on staphylococcus aureus comes second, and the inhibitory effect on colibacillus is relatively poor.

Description

technical field [0001] The invention belongs to a preservative or a preservative, in particular to the antibacterial application of the natural plant purslane. Background technique [0002] Purslane belongs to the genus Portulaca oleracea, also known as ant vegetable or purslane. It is distributed all over my country, especially in temperate, subtropical and tropical regions. Purslane has strong adaptability to the environment, has the characteristics of waterlogging and drought tolerance, strong vitality, rapid growth, etc., and is convenient to collect. Purslane is mostly born in fields, roadsides and wastelands, and has always been regarded as a common weed in farmland. In fact, purslane also has high medicinal and edible value, and it is an "earth ginseng" that has not been fully valued. Purslane is a delicacy gifted by nature to human beings. It has a cold and acidic taste and is rich in nutrition. Eating it can relieve the heat of the summer and replenish the Yin a...
