Preparation method of compounded fruit and vegetable cleaning agent of kadsura longepedunculata extract and oil-tea-cake extract

Abstract

The invention discloses a preparation method of a compounded fruit and vegetable cleaning agent of a kadsura longepedunculata extract and an oil-tea-cake extract. The method comprises the following steps: with an ethyl alcohol/acetone method extract of kadsura longepedunculata and an ethyl alcohol method extract of an oil-tea-cake as raw materials, combining with a resin separation technology, respectively purifying the kadsura longepedunculata extract and the oil-tea-cake extract, and purifying the extract; freeze-drying to obtain extract powder; and mixing the kadsura longepedunculata with the oil-tea-cake extract powder to obtain the compounded fruit and vegetable cleaning agent. The compounded fruit and vegetable cleaning agent is capable of cleaning unsanitary things such as soil, dirt, pesticides, germs and worm eggs on the surfaces of fruits and vegetables, does not affect the freshness of the fruits and vegetables within the shelf life, has the advantages of being high in biosecurity, low in toxicity, high in efficiency, low in amount, excellent in properties of cleaning, decontaminating and removing pesticides on the fruit and vegetable fruits, wide in bacteria and antimicrobial spectrum and high in bacteriostatic ability, is capable of cleaning dirt, microorganisms and worm eggs on the surfaces of fruits and vegetables, and does not change the nutrients and tastes of the 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.

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...
