Embodiment 1

[0025] Weigh 100 parts of attapulgite in a pre-mixer, and spray oregano essential oil accounting for 15% of the attapulgite mass fraction into the pre-mixer under stirring; after the spraying is finished, grind it in a Raymond mill for 2 hours for later use;

[0026] At a stirring rate of 2000 rpm, disperse Tween 20 and linseed oil in water, then add hot melted lauric acid dry oil, continue stirring for 30 minutes and set aside. Among them, the mass fraction of Tween 20 in the system is 0.05%, the mass fraction of linseed oil in the system is 10%, and the mass fraction of lauric acid dry oil in the system is 5%;

[0027] Take 15 parts of the prepared oil-in-water emulsion in the blender, and spray it on the surface of the attapulgite carrying oregano essential oil by spraying. After the spraying, continue to stir for 20 minutes, and then transfer the mixture to the roller machine. Thin flakes of 1~2mm are finally dried at 80°C, crushed, and packaged to obtain samples. The min...

Embodiment 2

[0029] Weigh 100 parts of attapulgite in a pre-mixer, spray carvacrol with a mass fraction of attapulgite of 40% into the pre-mixer under stirring, and grind in a Raymond mill for 3 hours after the spraying is over;

[0030] At a stirring rate of 3000 rpm, disperse Tween 60 and soybean oil in water, then add hot melted lauric acid dry oil, continue stirring for 20 minutes and set aside. Among them, the mass fraction of Tween 60 in the system is 0.25%, the mass fraction of soybean oil in the system is 5%, and the mass fraction of lauric acid dry oil in the system is 10%;

[0031] Take 20 parts of the prepared oil-in-water emulsion in the blender, and spray it on the surface of the attapulgite loaded with carvacrol by spraying. After the spraying, continue stirring for 15 minutes, and then transfer the mixture to the roller machine. Thin flakes of 1~2mm are finally dried at 80°C, crushed, and packaged to obtain samples. The minimum inhibitory concentration test results of the s...

Embodiment 3

[0033] Weigh 100 parts of attapulgite in the pre-mixer, spray attapulgite mass fraction 25% carvacrol and 15% cinnamaldehyde compound plant essential oil into the pre-mixer under stirring, after the spraying is finished, Grind in Raymond mill for 4h for later use;

[0034] At a stirring rate of 5000 rpm, disperse Tween 40, corn rapeseed oil and mixed vegetable oil in water, then add hot melted lauric acid dry oil, keep stirring for 25 minutes and set aside. Among them, the mass fraction of Tween 40 in the system is 0.1%, the mass fraction of corn oil in the system is 2.5%, the mass fraction of rapeseed oil in the system is 2.5%, and the mass fraction of lauric acid dry oil in the system 15%;

[0035] Take 25 parts of the prepared oil-in-water emulsion in a blender, and spray it onto the surface of the attapulgite pre-loaded with carvacrol and cinnamaldehyde compound plant essential oil by spraying. After the spraying, continue stirring for 20 minutes, and then transfer the mi...

Abstract

The invention discloses a method for preparing an oil-in-water emulsion coated plant essential oil by using glycerol monolaurate. Attapulgite is used for supporting plant essential oil, glycerol monolaurate is used for preparing oil-in-water emulsion, the oil-in-water emulsion with hydrophilic effect is spread on the surface of the attapulgite for supporting the plant essential oil, and then effective coating of the plant essential oil is achieved. The defect that plant essential oil is easy to volatilize is overcome, a preparation system is stable, the process operation is simple, the raw materials belong to permitted raw materials in a feed catalogue, and the product can be used for safe animal breeding.

Description

technical field [0001] The invention relates to a simple method for coating plant essential oils, in particular to a method for preparing oil-in-water emulsions for coating plant essential oils by using monoglyceride laurate, which is mainly used to replace antibiotics in the process of livestock and poultry breeding, and belongs to the field of animal feed . Background technique [0002] Bacterial drug resistance that has emerged in recent years has aroused widespread concern, especially the problem of bacterial drug resistance caused by the extensive use of antibiotics in animal breeding. Plant essential oil has the characteristics and advantages of animal metabolism and absorption, no residue, no pollution, no drug resistance, etc., and has been widely used in the production of livestock and poultry feed in recent years. Plant essential oils can improve animal production performance, body immunity, antioxidant capacity, intestinal flora and meat quality (Guangdong Animal...
