Embodiment 1

[0022] Embodiment 1: The formula research of OHAA poultry egg coating preservative

[0023] 1 Test method

[0024] 1.1 Determination of the amount of ethanol added

[0025] Absolute ethanol has good comprehensive properties, not only beneficial to the dissolution of OHAA, reducing viscosity, speeding up the film forming speed, shortening the film forming time, but also reducing the interaction between OHAA molecules and water molecules due to the interaction between ethanol molecules and water molecules. The bonding between molecules is promoted, and the film-forming performance is improved. The amount of absolute ethanol added needs to be controlled at an appropriate ratio in order to achieve a better defoaming effect. In the experiment, weigh a certain amount of OHAA, add ethanol according to the ratio of OHAA: absolute ethanol = 1:1~8 (weight ratio), stir evenly after adding, and observe the influence of ethanol on the dissolution effect of OHAA.

Embodiment 2

[0065] A coating preservative for poultry eggs, consisting of the following ingredients in parts by weight:

[0066]

[0067] The preparation method is: as figure 1 As shown, first heat and melt the ethylene oxide higher fatty alcohol, add absolute ethanol after cooling, stir slowly until fully dissolved, then add water, Tween 80, glycerin, palm oil, stir evenly, and finally remove it under vacuum gas, packaging.

[0068] Continue to carry out applied research to the poultry egg coating preservative of the present embodiment, the results are as follows:

[0069] 1 Test method

[0070] Chitosan poultry egg coating preservative, fatty alcohol polyoxyethylene ether (AEO) poultry egg coating preservative and polyvinyl alcohol poultry egg coating preservative were selected as controls to compare the fresh-keeping effect of OHAA poultry egg coating preservative Make an evaluation.

[0071] 1.1 Preparation method

[0072] Chitosan poultry egg coating preservative, AEO poultry...

Embodiment 3

[0114] A coating preservative for poultry eggs, consisting of the following ingredients in parts by weight:

[0115]

[0116] The preparation method is: first, heat the higher fatty alcohol of ethylene oxide to 55°C to melt it, then slowly add absolute ethanol at a speed of 150 rpm, and after the higher fatty alcohol of ethylene oxide is fully dissolved, then slowly Add water, stir evenly, then add Tween 80, glycerin, palm oil, and nisin in sequence, shear and emulsify the above mixture at a speed of 3000 rpm, vacuum degas the homogeneous liquid, and pack.

Abstract

The invention discloses an egg coating preservative which takes oxyethlene higher aliphatic alcohol as a main coating forming material and takes absolute ethyl alcohol, polysorbate 80, glycerol and palm oil as auxiliary materials. The invention also discloses a preparation method of the egg coating preservative. The egg coating preservative has the characteristics of being good in coating forming property and moisture retention, ensuring that the appearance of a coated product is beautiful, and the like, can effectively prevent the invasion of microorganisms and the moisture loss of the egg product, can adjust gas compositions to restrain an egg white thinning effect, has a good preservation effect, and has effects which are obviously superior to those of common egg coating preservatives.

Description

technical field [0001] The invention relates to a preservative for coating film, in particular to an ethylene oxide higher fatty alcohol poultry egg coating preservative, and also relates to its preparation method. Background technique [0002] Poultry egg coating preservative can form a thin film on the surface of poultry egg products, thereby preventing the invasion of microorganisms and reducing the evaporation of water in the product. In addition, it can also form a certain closed environment to inhibit the release of carbon dioxide in poultry eggs and avoid pH value. The egg white caused by the elevation is thinned, thereby prolonging the shelf life of the product. With the gradual deepening of research on poultry egg coating preservation technology, the selection of materials for poultry egg coating preservation agents is more extensive and diversified, such as polyvinyl alcohol, liquid paraffin, mineral oil, vaseline and other chemical materials, propolis, chitosan an...
