Embodiment 1

[0011] Embodiment 1: Weigh 6KG licorice, 4KG pine needles and 3KG rosemary according to the specified ratio, wash, chop and mix, then put the mixture into a multifunctional extraction tank, add water 4 times the quality of the mixture, and adjust the extraction tank The pressure is 1.5MPa, the temperature is 35°C, extract 3 times, 1.5 hours each time, to obtain a mixed extract, and then let the extract stand for 18 hours, and take the supernatant to pass through the apertures of 100 mesh, 200 mesh and 400 mesh in turn. Filter three times with silk screen, then add 1KG of Forsythia leaf extract and 1KG Scutellaria baicalensis extract to the filtrate, then put it into a vacuum concentration tank, concentrate at 3°C ​​to obtain extract, and finally dry the extract through The tower is dried, and after drying, it is pulverized to 100 mesh by a universal pulverizer.

Embodiment 2

[0012] Embodiment 2: Take by weighing 10KG licorice root, 6KG pine needles and 5KG rosemary according to the specified ratio, wash, chop and mix, then put the mixture into a multifunctional extraction tank, add water 4 times the quality of the mixture, and adjust the extraction tank The pressure is 1.5MPa, the temperature is 38°C, extract 3 times, each time for 1.5 hours, to obtain a mixed extract, and then let the extract stand for 18 hours, and take the supernatant to pass through the apertures of 100 mesh, 200 mesh and 400 mesh in turn. Filter the silk screen three times, then add 1.5KG of Forsythia leaf extract and 2KG of Scutellaria baicalensis extract to the filtrate, then put it into a vacuum concentration tank, concentrate at 3°C ​​to obtain the extract, and finally pass the extract through The drying tower is used for drying, and after drying, it can be crushed to 100 mesh by a universal pulverizer.

Embodiment 3

[0013] Embodiment 3: Take by weighing 10KG licorice root, 5KG pine needles and 4KG rosemary according to the specified ratio, wash, chop and mix, then put the mixture into a multifunctional extraction tank, add water 4 times the quality of the mixture, and adjust the extraction tank The pressure is 1.5MPa, the temperature is 35-38°C, extract 3 times, each time for 1.5 hours, to obtain a mixed extract, and then let the extract stand for 18 hours, take the supernatant and pass through the apertures of 100 mesh, 200 mesh and Filter three times with a 400-mesh screen, then add 1KG of Forsythia leaf extract and 1KG Scutellaria baicalensis extract to the filtrate, then put it into a vacuum concentration tank, concentrate at 3°C ​​to obtain the extract, and finally extract the extract It is dried by a drying tower, and after drying, it is crushed to 100 mesh by a universal pulverizer. After a comprehensive comparison, under the same concentration conditions, the plant-derived natural...

Abstract

The invention discloses a preparation method of plant source natural freshness-retaining preservative with liquorice as raw materials. The preparation method includes the following steps that liquorice, pine needles and rosemary are weighed out according to regulated proportions, completely washed, shredded and then mixed, the mixture is placed in a multifunctional extraction tank, water with the mass four times that of the mixture is added, the pressure of the extraction tank is adjusted to be 1.5 MPa, the temperature ranges from 35 DEG C to 38 DEG C, extraction is conducted three times, each time of extraction is conducted for 1.5 hours, mixed extract is obtained, the extract is subjected to static settlement for 18 hours, supernatant liquid is taken and sequentially passes through silk screens with the hole diameters of 100 meshes, 200 meshes and 400 meshes for three times of filtration, 1 KG of forsythia suspense leaf extract and 1 KG of scutellaria baicalensis extract are added to the filter liquid, the filter liquid is placed in a vacuum concentration tank and concentrated at the temperature of 3 DEG C, extract is obtained, finally, the extract is dried through a drying tower, and the dried extract is smashed to be 100 meshes through a universal pulverizer.

Description

technical field [0001] The invention relates to a preparation method of a natural food preservative, in particular to a plant-derived natural fresh-keeping preservative with licorice as a main raw material, belonging to the field of food additives. Background technique [0002] In order to keep food for a long time, prevent food spoilage, and to ensure the quality and taste of food, it is often necessary to add food preservatives and preservatives during storage or processing of various foods. At present, there are three main types of preservatives commonly used in the market: potassium sorbate, nisin and sodium lactate. Some of these preservatives are more likely to deteriorate when the initial number of bacteria is large, and some can only extend the shelf life for 3-5 days. God, some of them have high costs, increase product costs, and the overall effect is not ideal. Common preservatives are benzoic acid, sorbic acid and its salts, and parabens, which are relatively che...
