Description

Technical Field

[0001] The invention relates to the technical field of plant essential oil coating, in particular to a preparation method of plant essential oil coated with mono- and di-stearate glycerides after simple coating with palm oil. Background Art

[0002] "All medicines are poisonous to some extent." The harm of antibiotics to animals and humans is becoming more and more obvious. The European Union has banned and restricted the use of most antibiotics. At present, the Ministry of Agriculture and Rural Affairs of China has implemented a comprehensive ban on antibiotics. Plant essential oils can effectively kill bacteria without developing drug resistance and are an excellent antibacterial resource. Plant essential oils can improve intestinal health and immunity through antibacterial and antioxidant effects, thereby improving the production performance of livestock such as pigs and poultry. "Phytonutrients" and "phytochemicals" extracted from plants are helpful to human health in many ways, including promoting tumor death and improving resistance to infectious diseases. They have been used to improve health for thousands of years.

[0003] Plant essential oils are plant-specific aromatic substances extracted from flowers, leaves, roots, bark, fruits, seeds, resins, etc. of herbal plants, and are extracted by distillation, pressing, etc. Due to its advantages such as being green, environmentally friendly, efficient, residue-free, incompatible, and non-resistant, its application range is gradually expanding. Plant essential oils are currently used as a substitute for antibiotics and have broad application prospects in animal production as a new feed additive.

[0004] However, due to the inherent characteristics of essential oils, they are volatile and easily oxidized; in addition, the antibacterial effects of different types and contents of essential oils vary greatly; when essential oils are simply added to feed, the effectiveness is greatly reduced. Summary of the invention

[0005] The object of the present invention is to provide a method for preparing a coated plant essential oil, which can inhibit the growth and reproduction of pathogenic bacteria of livestock and poultry, and has different degrees of bactericidal and antibacterial effects on common enteritis-causing Salmonella, Escherichia coli, Staphylococcus aureus, Eimeria, etc. It also has a preventive and therapeutic effect on viral diseases such as avian influenza. At the same time, it can reduce the incidence of inflammation of the glandular gastritis, respiratory system and reproductive system of poultry. It can eliminate the problem of bacterial resistance caused by the use of antibiotics, improve animal growth performance, improve animal immunity, have a strong antioxidant effect, improve the meat flavor and increase the water content of the meat system, and obtain better benefits.

[0006] In order to achieve the above object, the present invention is implemented by the following technical scheme: a preparation method of coated plant essential oil, comprising the following steps: (1) Adding a carrier into a mixer; (2) heating and melting the plant essential oil and the coating material, and then spraying them into a mixer, and mixing them for a certain period of time to obtain plant essential oil particles; (3) heating and melting mono- and di-stearyl glycerides; (4) Spray the melted mono- and di-stearate glycerides evenly on the plant essential oil particles and mix them for a certain period of time to obtain coated plant essential oil.

[0007] Furthermore, the amount of the carrier in step (1) is 2-10 times the mass of the plant essential oil.

[0008] Furthermore, the plant essential oil in step (2) is any one or any combination of cinnamaldehyde, carvacrol, thymol, and eugenol.

[0009] Furthermore, the coating material in step (2) is palm oil, and the amount used is 0.5-5 times that of the plant essential oil.

[0010] Furthermore, the heating and melting temperature in step (2) is between 40°C and 60°C.

[0011] Furthermore, the heating and melting temperature in step (3) is between 65°C and 85°C.

[0012] Furthermore, in step (4), the mass ratio of the plant essential oil particles to the mono- and di-stearate glycerides is 1:1-5.

[0013] Furthermore, the plant essential oil consists of cinnamaldehyde or thymol or carvacrol or eugenol and palm oil, mono- and di-stearate glycerides, and silicon dioxide.

[0014] Beneficial effects of the invention: The invention provides a method for preparing coated plant essential oils, and the special coating process prevents the effective ingredients from being oxidized or volatilized, thereby covering up the pungent smell; the plant essential oil product prepared by the invention has good stability, a scientific component ratio, and stronger antibacterial function and biological activity.
