Preparation method of fruit and vegetable cleaning agent compounded with Schisandra chinensis extract and camellia oleifera cake extract

Abstract

The invention discloses a preparation method of a fruit and vegetable cleaning agent compounded with Schisandra chinensis extract and camellia oleifera cake extract. The invention adopts the ethanol / acetone method extract of schisandra chinensis and the ethanol method extract of camellia oleifera cake, combined with resin separation technology , respectively purify the extract of Schisandra chinensis and the extract of camellia oleifera, after purifying the above extracts, freeze-dry to obtain extract powder, and mix the extract powder of schisandra chinensis and camellia oleifera cake to obtain a compound fruit and vegetable cleaning agent. The compound fruit and vegetable cleaning agent of the present invention can ensure that unhygienic things such as soil, dirt, pesticides, germs, insect eggs, etc. on the surface of fruits and vegetables are cleaned, and does not affect the freshness of fruits and vegetables during the shelf life, and has biological High safety, low toxicity, high efficiency, less dosage, excellent performance in cleaning and decontamination and removal of pesticides on the surface of fruits and vegetables, broad sterilization and antibacterial spectrum, and strong antibacterial ability; not only can wash away the dirt on fruits and vegetables , microorganisms and insect eggs, and will not change the nutritional content and taste of fruits and vegetables.

Description

technical field [0001] The invention relates to a cleaning agent and a preparation method thereof, in particular to a preparation method of a fruit and vegetable cleaning agent compounded with Schisandra chinensis extract and camellia oleifera cake extract. Background technique [0002] With the rapid development of my country's agriculture, the output of fruits and vegetables has increased year by year, the scope of use of pesticides has continued to expand, and the amount of pesticides has continued to increase. Fruits and vegetables are the most consumed food in people's daily life. The amount of residual pesticides and industrial pollutants adsorbed on fruits and vegetables is large, which has already posed a serious hazard to public health. According to statistics, the pesticides ingested by humans through food accounted for more than 90% of the total amount of pesticides ingested by humans, and the pesticides ingested through eating fruits and vegetables accounted for ...

Problems solved by technology

However, there are still many problems in the industrial application of its antibacterial active ingredients

For example: the antibacterial effect of the antibacterial active ingredients is affected by the pH value of the solvent; the ordinary extraction process will cause a large loss of antibacterial active ingredients in Schisandra chinensis and camellia oleifera cake, the antibacterial effect is not ideal, and the end product contains more impurities, etc. Difficult problem; with the same dosage, the antibacterial effect of the antibacterial agent extracted from Schisandra chinensis and Camellia oleifera cake is not as good as that of chemically synthesized antibacterial agent

For the antibacterial active ingredients of Schisandra chinensis, the optimization of extraction process, the separation of effective antibacterial ingredients, the antibacterial properties, and the application of antibacterial active ingredients in fruit and vegetable food cleaning agents are not sufficient.

Therefore, the development and use of Schisandra chinensis extract and Camellia oleifera cake extract as natural fruit and vegetable food cleaning agents still need to solve the problems of poor stability after long-term storage, reduced antibacterial activity, and insufficient application research.
