Problems solved by technology

[0002] Microorganisms are widely distributed in nature, and food will inevitably be polluted by certain types and quantities of microorganisms. When the environmental conditions are suitable, they will grow and reproduce rapidly, causing food spoilage and deterioration, especially for raw foods. Pollution not only reduces the nutritional and hygienic quality of food, but may also endanger human health
In order to prevent this kind of harm, raw foods need to be frozen or added with food fungicides for preservation and sterilization before eating, and most of the chemical fungicides contain or potentially contain a certain degree of toxicity, and at the same time, they will also cause adverse effects on the natural ecological environment.

Embodiment 1

[0012] Example 1: Mix the spice essential oils containing 15 parts of cinnamaldehyde, 20 parts of anethole, 55 parts of thymol, and 10 parts of salicylaldehyde in an airtight glass or stainless steel container to obtain a plant essential oil composition; take 5 parts of plant The essential oil composition is dissolved in 95 parts of edible alcohol to obtain an essential oil solution containing 5% of the plant essential oil composition, and then when mixing 5mL of 5% essential oil solution per liter according to the volume of the medium in the plate, it can completely kill the smeared on the medium. Five kinds of harmful bacteria are common in food, such as Escherichia coli, Staphylococcus aureus, Salmonella, Listeria monocytogenes, and Vibrio parahaemolyticus.

Embodiment 2

[0013] Example 2: Mix the spice essential oils containing 5 parts of cinnamaldehyde, 20 parts of anethole, 65 parts of thymol and 10 parts of salicylaldehyde in an airtight glass or stainless steel container to obtain a plant essential oil composition; take 5 parts of plant Essential oil composition, 5 parts of propylene glycol, 12 parts of emulsifier, 78 parts of distilled water emulsify the plant essential oil composition to obtain an emulsified essential oil solution containing 5% of the plant essential oil composition, then mix 8mL per liter according to the volume of the medium in the plate 5 % emulsified essential oil solution, it can completely kill Escherichia coli, Staphylococcus aureus, Salmonella, Listeria monocytogenes, Vibrio parahaemolyticus and other food common harmful bacteria smeared on the culture medium.

Embodiment 3

[0014] Example 3: Mix the spice essential oils containing 25 parts of cinnamaldehyde, 5 parts of anethole, 60 parts of thymol, and 10 parts of salicylaldehyde in a closed glass or stainless steel container to obtain a plant essential oil composition; take 5 parts of plant Dissolve the essential oil composition in 95 parts of edible alcohol to obtain an essential oil solution containing 5% of the plant essential oil composition, take 1ml of ground and dilute to 10% fish paste, add 0.2m of 5% essential oil solution, mix evenly, and act for 3 minutes; Then add 90ml of sterile water to dilute to 1000 times; take 1ml of the diluted solution in a petri dish, then pour 19ml of medium cooled to 40~50°C, shake well, put it in 37°C for 24 hours, then count the colonies to calculate the sterilization rate . As a result of the experiment, the plant essential oil composition of the present invention has the characteristic of significantly killing harmful bacteria in fish meat, and the bact...

Abstract

The invention discloses a plant essential oil composition for killing harmful bacteria of uncooked food. Edible spices rich in cinnamic aldehyde, anethole, thymol and salicylic aldehyde are used as the components of the composition; and the composition comprises the following four components in part by weight: 5 to 30 parts of cinnamic aldehyde, 5 to 25 parts of anethole, 53 to 80 parts of thymoland 1 to 15 parts of salicylic aldehyde. The composition is efficient, natural, safe, non-toxic and convenient to use, and can be used for sterilization of the uncooked food; and before use, the composition is dissolved and diluted by adopting a solvent such as edible alcohol, propylene glycol, grease or the like, or emulsified by adopting other carrier such as starch, Arabic gum or the like, andthen added into the uncooked food to kill common harmful bacteria so as to improve the safety of the uncooked food.

Description

technical field [0001] The invention relates to a plant essential oil composition for killing harmful bacteria in raw foods, belonging to the technical field of food chemistry. Background technique [0002] Microorganisms are widely distributed in nature, and food will inevitably be polluted by certain types and quantities of microorganisms. When the environmental conditions are suitable, they will grow and reproduce rapidly, causing food spoilage and deterioration, especially for raw foods. Pollution not only reduces the nutritional and hygienic quality of food, but may also endanger human health. In order to prevent this hazard, raw foods need to be frozen or added with food fungicides for fresh-keeping and sterilization before consumption. Most of the chemical fungicides contain or potentially contain a certain degree of toxicity, and at the same time, they will also cause adverse effects on the natural ecological environment. With the improvement of people's living and ...
