Background

The pricklyash peel is a small deciduous tree of the genus pricklyash in the family Rutaceae, has the effects of expelling cold, relieving pain, killing insects, inhibiting bacteria and the like, and is not only a spice, but also an important traditional Chinese medicine. The pericarp, seed, branch and leaf of pricklyash peel have certain medicinal effects and can be used as medicine. Wild pepper planting is widely distributed in China, but at present, wild pepper planting is mostly used for picking wild pepper seeds and used as food spice, and application research on other parts of wild pepper and application research in other fields is less. Researches show that the extract or volatile oil of the Chinese prickly ash has remarkable effects in bacteriostasis, antibiosis and the like.

In the process of processing, transporting and storing foods, strict requirements on environmental sanitation are imposed. The food contains rich nutrition, is easy to breed bacteria, generate peculiar smell and the like, and causes pollution and influences the flavor of the food. In families, refrigerators or freezers are used for storing foods, and bacteria are usually prevented from breeding by cleaning and using chemical sterilizing disinfectants at regular intervals, and adsorbents are placed for removing peculiar smell; in food shops, food cabinets, food workshops, cold houses or food storages, etc., ultraviolet irradiation sterilization and chemical sterilization and disinfection are generally adopted to prevent bacteria from breeding, and adsorbents are also placed to remove peculiar smell. Although the effects of sterilization, disinfection and peculiar smell removal can be achieved, the chemical sterilization disinfectant has certain toxicity, and residues are easy to exist when the chemical sterilization disinfectant is frequently used or the usage amount is too large, so that food pollution is caused, and the health of people is further influenced; the chemical sterilizing disinfectant is mostly used in the environment cleaning process, and cannot be stored with food for a long time; the sterilization by ultraviolet irradiation is needed to be used when no one is available; the food can be stored in the process of removing peculiar smell by only placing an adsorbent, and can not play a good role in disinfection and sterilization. Therefore, it is necessary to develop a safe and effective antibacterial deodorant which can be stored together with food to improve the safety of food during processing and storage.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Examples

The embodiment of the invention provides a composite antibacterial deodorant, which is suitable for being used in the food processing and storage processes. The composite antibacterial deodorant comprises a volatile slow-release part and a dry material part.

The volatile slow-release part comprises a buffer medium and oil liquid, and the oil liquid is absorbed and buffered in the buffer medium. The buffer medium can be made of sponge, fiber and other materials capable of repeatedly absorbing oil. The oil liquid comprises at least one of pericarpium Zanthoxyli volatile oil, semen Zanthoxyli volatile oil and oleum Menthae Dementholatum.

The dry material part comprises at least one of Chinese prickly ash leaf powder, chinese prickly ash shell powder, chinese prickly ash seed powder, peppermint powder, etc. Wherein the Chinese prickly ash leaf powder, chinese prickly ash shell powder and Chinese prickly ash seed powder are respectively dry powder of Chinese prickly ash leaf, chinese prickly ash seed shell and Chinese prickly ash seed kernel; the herba Menthae powder is herba Menthae leaf dry powder or mixed dry powder of branches and leaves containing 10-30% of herba Menthae branches and stems.

When the composite antibacterial deodorant is used, substances volatilized by the volatilization slow-release part of the composite antibacterial deodorant need to overflow after passing through the dry material part.

Wherein, the volatile oil of the pepper leaves can be prepared by a microwave extraction method: weighing fresh pepper leaves, crushing, and using diethyl ether as an extractant, wherein the weight ratio of the pepper leaves to the diethyl ether is controlled to be 1:2-3; soaking in diethyl ether for 20-30 min, then placing into microwave equipment, performing microwave (power is about 300-500W) irradiation treatment for 30-60 s, and then filtering and collecting filtrate; and adding anhydrous sodium sulfate into the filtrate, drying for 12-20h, filtering, collecting the filtrate, and removing diethyl ether by rotary evaporation of the filtrate to obtain the pericarpium zanthoxyli leaf volatile oil. The pepper leaves of the oil pepper picked in 6-9 months can be selected as raw materials.

The pericarpium Zanthoxyli volatile oil can be extracted by supercritical extraction method: weighing pericarpium Zanthoxyli, pulverizing, extracting with supercritical carbon dioxide extraction device at 60deg.C under 30-35Mpa for 1.5-2 hr to obtain pericarpium Zanthoxyli volatile oil.

The pricklyash seed volatile oil can be prepared by a squeezing method: parching semen Zanthoxyli, and mechanically squeezing to separate oil from oil to obtain semen Zanthoxyli volatile oil.

Peppermint oil can be obtained by distillation and extraction.

Of course, the zanthoxylum leaf volatile oil, the zanthoxylum husk volatile oil, the zanthoxylum seed volatile oil and the peppermint oil can also be obtained by other reported preparation methods. The other preparation methods are not described in detail herein.

The volatile oil of the pepper leaves, the pepper shells and the pepper seeds contains rich volatile substances such as linalool, myrcene, 4-terpineol and the like, wherein the linalool has antibacterial and bactericidal functions; myrcene and 4-terpineol have pleasant special fragrance, have deodorizing and deodorizing effects, and make air more fresh and comfortable. The peppermint oil and the peppermint powder contain rich menthol, and the menthol has the functions of sterilizing, preserving, repelling mosquitoes and the like, and is a safe and edible flavoring agent.

The content ratio of linalool, myrcene, 4-terpineol and the like in different parts of the pepper is different, and the combined use can comprehensively utilize the different parts of the pepper and make the content ratio more proper. The volatile oil/powder and the peppermint oil/powder at different positions of the pepper are compatible for use, so that the composite antibacterial deodorant has antibacterial, deodorizing, mosquito-repellent and other effects, has safe and pleasant fragrance, is suitable for long-term use in food processing and storage environments, reduces bacterial breeding, prevents mosquito breeding, keeps air in the storage environments fresh, and is harmless to human bodies.

Examples

The composite antibacterial deodorant and antibacterial deodorizing device is different from example 3 in that the filler in the first dry material layer 21 is pricklyash leaf powder (dry powder) with the granularity of about 10-20 meshes; the fillers in the second dry material layer 22 are pericarpium Zanthoxyli powder and semen Zanthoxyli powder with particle size of about 15-35 mesh; the filler in the third dry material layer 23 is peppermint powder and pricklyash leaf powder with the granularity of about 5-10 meshes.

Examples

As shown in fig. 2, the antibacterial deodorizing device comprises an inner shell 3 filled with a volatile slow-release part 1, and an outer shell 4 positioned outside the inner shell 3, wherein a dry material part 2 is filled in the outer shell 4. The inner shell 3 is communicated with a filling area of the dry material part 2 in the outer shell 4 through a plurality of first slow release holes; the outer casing 4 communicates with the outside via a plurality of second sustained release holes, i.e., the dry material part 2 communicates with the outside.
