Embodiment 1

[0011] Example 1: Wash and chop red bayberry leaves and tealeaves by weighing, then put the mixture into a multifunctional extraction tank, add 4 times the water of the mixture quality, adjust the extraction tank pressure to 1.5MPa, and the temperature to be 35 At ~38°C, extract twice, each time for 2 hours, to obtain bayberry leaf extract and tea polyphenol extract. Then the cloves were washed and pulverized, then soaked in edible ethanol, then extracted by a Soxhlet extractor, and then concentrated by a rotary evaporator to remove residual ethanol to obtain an ethanol extract of cloves. Then weigh 8KG of bayberry leaf extract, 5KG of tea polyphenol extract, 5KG of ethanol extract of clove, 1KG of scutellaria baicalensis extract, and 2KG of forsythia leaf extract by weight, and fully mix to obtain the plant source of bayberry leaf as raw material Natural fresh-keeping preservatives 1.

Embodiment 2

[0012] Embodiment 2: wash by weighing waxberry leaves and tealeaves, mix after chopping, then put the mixture into a multifunctional extraction tank, add water 4 times the quality of the mixture, adjust the pressure of the extraction tank to 1.5MPa, and the temperature is 35 At ~38°C, extract twice, each time for 2 hours, to obtain bayberry leaf extract and tea polyphenol extract. Then the cloves were washed and pulverized, then soaked in edible ethanol, then extracted by a Soxhlet extractor, and then concentrated by a rotary evaporator to remove residual ethanol to obtain an ethanol extract of cloves. Then weigh 12KG of bayberry leaf extract, 3KG of tea polyphenol extract, 3KG of ethanol extract of clove, 2KG of scutellaria baicalensis extract, and 1KG of forsythia leaf extract by weight, and fully mix to obtain the plant source of bayberry leaf as raw material Natural fresh-keeping preservatives 2.

Embodiment 3

[0013] Embodiment 3: wash by weighing bayberry leaf and tealeaves, mix after chopping, then put the mixture in the multifunctional extraction tank, add 4 times the water of the mixture quality, adjust the extraction tank pressure to be 1.5MPa, and the temperature is 35 At ~38°C, extract twice, each time for 2 hours, to obtain bayberry leaf extract and tea polyphenol extract. Then the cloves were washed and pulverized, then soaked in edible ethanol, then extracted by a Soxhlet extractor, and then concentrated by a rotary evaporator to remove residual ethanol to obtain an ethanol extract of cloves. Then weigh 10KG of bayberry leaf extract, 4KG of tea polyphenol extract, 3KG of ethanol extract of clove, 1.5KG of scutellaria baicalensis extract, and 1KG of forsythia leaf extract by weight, and fully mix to obtain the plant of bayberry leaf as raw material Source natural fresh-keeping preservatives3. After a comprehensive comparison, under the same concentration conditions, the pl...

Abstract

The invention discloses a botanical natural fresh keeping antiseptic prepared from red bayberry leaf. The antiseptic is prepared from, by weight, 8-12 parts of strawberry tree leaf extract, 3-5 parts of tea polyphenol extract, 3-5 parts of Syzygium aromaticum ethanol extract, 1-2 parts of Radix Scutellariae extract and 1-2 parts of Forsythia suspense leaf extract. Difficult fresh keeping of present natural antiseptics and difficult effective prolongation of the preservation time of present natural fresh keeping agents are overcome in the invention. Effective compatibility combination of strawberry tree leaves and other plants makes the botanical natural fresh keeping antiseptic greatly prolong the preservation time of foods and greatly improve the preservation freshness of the foods; and main raw materials are respectively prepared from pure natural raw materials, so the botanical natural fresh keeping antiseptic has the advantages of safety, reliability, low preparation cost, and easy large-scale promotion.

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 bayberry leaves as the main raw material, which belongs 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, wh...
