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 a silk screen, then add 1KG of Forsythia extract and 1KG salt 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 a drying tower for drying , after drying, it can be crushed 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 three times with a silk screen, then add 1.5KG of forsythia extract and 2KG salt to the filtrate, then put it into a vacuum concentration tank, concentrate at 3°C ​​to obtain an extract, and finally pass the extract through a drying tower Dry, and after drying, pulverize 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 extract and 1KG salt to the filtrate, then put it in a vacuum concentration tank, concentrate at 3°C ​​to obtain the extract, and finally pass the extract through the drying tower Drying is carried out, and after drying, it is pulverized to 100 mesh by a universal pulverizer. After a comprehensive comparison, under the same concentration conditions, the plant-derived natural fresh-keeping pr...

Abstract

The invention discloses plant source natural freshness-retaining preservative with liquorice as raw materials. The plant source natural freshness-retaining preservative is characterized by being prepared from, by weight, 6-10 parts of liquorice extract, 4-6 parts of scutellaria baicalensis extract, 3-5 parts of rosemary extract, 1-2 parts of forsythia fructus extract and 1-2 parts of table salt. The limitation that according to existing natural preservative, freshness can be hardly effectively retained, and the shelf time can be hardly effectively prolonged is overcome. Through the effective compatibility and combination of extracted myrica ruba leaves and other plants, the shelf time of food can be greatly prolonged, the preservation freshness of the food is greatly improved, the main raw materials are all prepared from pure natural raw materials, and therefore the plant source natural freshness-retaining preservative is safe, reliable, low in manufacturing cost and easy to popularize on a large scale.

Description

technical field [0001] The invention relates to a natural food preservative and a preparation method thereof, 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 relat...
