Problems solved by technology

In 2012, Deng Yacheng and Ning Lei published "Antibacterial Activity and Application of 4 Kinds of Plant Essential Oils", Litsea Cubeba Essential Oil, Nanfeng Tangerine Essential Oil, Flycapne Essential Oil and Red Thistle Essential Oil all have antibacterial activity, but Litsea Cubeba Essential Oil It has a fresh lemon fruit fragrance, and other plant essential oils also have a special smell. Adding it to food or cosmetics may cause changes in the flavor of the food or the smell of the cosmetics, so it is limited to directly add it to food or cosmetics

Embodiment 1

[0038] step 1

[0039] Preparation method of plant extract containing cinnamaldehyde: steam distillation method Take 60kg of finely ground cinnamon bark powder, put it into a flask, add 160L of water, install a condenser, and heat to reflux for 10min. After cooling, pour it into a distillation bottle for steam distillation, and collect 80-100L of distillate.

[0040] The distillate was transferred to a separatory funnel and extracted twice with 40 L portions of ether. Discard the water layer, transfer the ether layer into a small test tube, add a small amount of anhydrous sodium sulfate to dry, pour out the extract after 20 minutes, and evaporate the ether in a water bath in a fume hood to obtain a plant extract containing cinnamaldehyde.

[0041] step 2

[0042] The preparation method of the plant extract containing eugenol: Weigh 15kg of clove flower buds, add 90L of water to soak in a distillation bottle, directly heat for steam distillation, and collect about 30L of dist...

Embodiment 2

[0049] step 1

[0050] Preparation method of plant extract containing cinnamaldehyde: steam distillation method Take 60kg of finely ground cinnamon bark powder, put it into a flask, add 160L of water, install a condenser, and heat to reflux for 10min. After cooling, pour it into a distillation bottle for steam distillation, and collect 80-100L of distillate.

[0051] The distillate was transferred to a separatory funnel and extracted twice with 40 L portions of ether. Discard the water layer, transfer the ether layer into a small test tube, add a small amount of anhydrous sodium sulfate to dry, pour out the extract after 20 minutes, and evaporate the ether in a water bath in a fume hood to obtain a plant extract containing cinnamaldehyde.

[0052] step 2

Embodiment 3

[0060] According to the method of Chinese Patent ZL.201810361279.4 Example 3, a food-grade plant-derived composite bacteriostatic agent composition containing cinnamon was prepared

[0061] Take cinnamon, rosemary, salvia miltiorrhiza, Huoxiang, and wild chrysanthemum dried traditional Chinese medicines and grind them with a traditional Chinese medicine grinder, and pass through a 100-mesh sieve for later use. Take 50g of sieved cinnamon powder, 20g of rosemary powder, 10g of salvia miltiorrhiza powder, 10g of Huoxiang powder and 10g of wild chrysanthemum powder and mix them evenly. The time is 2 hours, the extraction temperature is 60°C, then add water to make powder: water = 1:20, extract in a heating device at 103°C for 240min, collect volatile oil, filter and refine through filter paper, and obtain the food-grade plant of the present invention after packaging Source compound antibacterial composition.

Abstract

The invention provides a food-grade plant-derived composite bacteriostat composition. The food-grade plant-derived composite bacteriostat composition comprises, by weight percentage, 15-85% of cinnamyl aldehyde, 3-60% of eugenol, 3-15% of trans-methoxycinnamaldehyde or 0.2-15% of caryophyllene and the balance carrier which refers to all compounds which do not belong to active mixtures, and the food-grade plant-derived composite bacteriostat composition can also contain one or more of limonene, patchouli alcohol, trans-anise camphor, magnolol and berberine. The food-grade plant-derived composite bacteriostat composition has the advantages that the components of the food-grade plant-derived composite bacteriostat composition are green and environmentally friendly, the composition does not contain the special smell of plant essential oil and cannot cause food flavor change or cosmetic smell change, and the composition is good in broad-spectrum antimicrobial effect, widely applicable to food compositions or cosmetics, economical and feasible.

Description

technical field [0001] The present invention belongs to the field of food-grade plant-derived compound bacteriostat, more specifically relates to the field of natural food-grade plant-derived compound bacteriostat and relates to the application of the food-grade plant-derived compound bacteriostat in various fields of its consumer products application. Background technique [0002] The food-grade plant-derived compound antibacterial agent is mainly to prevent the product from being corrupted or unstable due to the influence of microorganisms. To make food and cosmetics have a certain shelf life, certain measures must be taken to prevent microbial infection and reproduction. [0003] Practice has proved that the use of food-grade plant-derived compound bacteriostatic agents is one of the most economical, effective and easiest ways to achieve the above goals. Most of the food-grade plant-derived compound antibacterial agents used in my country's current food production are a...
