Embodiment 1

[0011] Preparation of forsythia essential oil:

[0012] ①Raw material processing: Freeze-dry the peel and seeds of Forsythia and pulverize to 100nm;

[0013] 2. distillation: get 2000g step 1. Gained Forsythia granules are placed in a steam distiller and carry out distillation treatment. The pressure of the distiller is 35Mpa, and the distillation time is 48h to obtain steam containing Forsythia quintessence oil;

[0014] 3. adsorption: utilize adsorbent to step 2. gained and contain the steam of forsythia essential oil to carry out adsorption treatment, described adsorbent is activated carbon, and its average particle diameter is 400nm, specific surface area 2000m g-1, and adsorbent consumption is 100g;

[0015] ④ Condensation and reflux: condense the vapor passing through the adsorbent and return it to the steam distiller;

[0016] ⑤Desorption: Use supercritical CO2 to desorb the adsorbent that has adsorbed Forsythia essential oil in step ③, the flow of supercritical CO2 is...

Abstract

A pure natural plant preservative is characterized in that the food preservative comprises 0.3%-1% by mass of fructus forsythiae essential oil and 0.5%-2% by mass of flos lonicerae essential oil.

Description

technical field [0001] The invention relates to a pure natural plant preservative and belongs to the field of food antiseptic. Background technique [0002] Food preservatives are food additives that can prevent spoilage caused by microorganisms and prolong the storage period of food. Food preservatives can be divided into organic chemical preservatives and inorganic chemical preservatives according to their properties. Different types of preservatives are used in different types. For example, common potassium sorbate is used to keep meat products, fruits and vegetables fresh, while benzoic acid and its salts are used in beverages, fruit wines, and liquid seasonings. However, a large intake of food containing chemical preservatives is extremely detrimental to human health, especially in the stage of frequent "food safety" problems, it is urgent to choose natural, non-toxic and low-cost food preservatives. [0003] Forsythia is one of the traditional Chinese medicines, whic...
