Embodiment 1

[0025] Prepare a new type of humic acid egg preservative film, which is prepared by the following components according to the quality: potassium humate 10kg, chitosan 15kg, acetic acid 0.25kg, alkyl polyglycoside 0.6kg, glycerin 0.6kg, guar gum 1.0 kg, water 60kg.

[0026] The above raw materials are all commercially available products, and there is no restriction on the manufacturer.

[0027] The preparation method comprises the following steps: firstly, dissolving 15kg of chitosan in 0.5% acetic acid aqueous solution, adding 0.6kg of glycerin after fully dissolving, and stirring evenly to prepare the chitosan composite mother liquor. Get 10kg humic potassium dissolving water 10kg, make potassium humic acid solution, then the guar gum of 1.0kg is dissolved in the above-mentioned potassium humic acid solution; Add the potassium humate solution of guar gum and stir evenly to obtain the mother liquor of humic acid egg preservative film. Finally, add 0.6 kg of alkyl polyglucosi...

Embodiment 2

[0029] Prepare novel humic acid egg fresh-keeping film, be prepared from following components by mass: Potassium humate 15kg, chitosan 20kg, acetic acid 0.75kg, alkyl polyglycoside 0.8kg, glycerin 0.8kg, guar gum 1.5kg kg, water 65kg.

[0030] The above raw materials are all commercially available products, and there is no restriction on the manufacturer.

[0031] Preparation method: firstly, 20kg of chitosan is dissolved in 1.5% acetic acid aqueous solution, after fully dissolving, 0.8kg of glycerin is added, stirred evenly, and the chitosan composite mother liquor is obtained. Get 15kg potassium humate and dissolve in 15kg water to make potassium humate solution, then dissolve the guar gum of 1.5kg in the above-mentioned potassium humate solution; Potassium humate solution dissolved in guar gum, stirred evenly to initially obtain humic acid egg preservative film mother liquor. Finally, add 0.8 kg of alkyl polyglucoside under the action of stirring, so that the composite so...

Embodiment 3

[0033] Preparation of novel humic acid egg preservative film is prepared from the following components by mass: potassium humate 20kg, chitosan 25kg, acetic acid 1.0kg, alkyl polyglycoside 1.0kg, glycerin 1.0kg, guar gum 2kg , 80kg of water.

[0034] The above raw materials are all commercially available products, and there is no restriction on the manufacturer.

[0035] Preparation method: firstly, 25kg of chitosan is dissolved in 2.0% acetic acid aqueous solution, after fully dissolving, 1.0kg of glycerin is added, stirred evenly, and the chitosan composite mother liquor is obtained. Get 20kg humic acid and dissolve in potassium hydroxide solution to make potassium humate solution, then dissolve 2.0kg of guar gum in the above-mentioned potassium humate solution; The mother liquor and the potassium humate solution dissolved in guar gum are stirred evenly to initially obtain the mother liquor of humic acid egg preservative film. Finally, add 1.0kg of alkyl polyglucoside unde...

Abstract

The invention provides an egg-preserving humic acid film and a preparation method and a using method thereof, and belongs to the field of food preservation. The egg-preserving humic acid film is a uniform mixture prepared from humic acid, chitosan, glycerol, alkyl polyglycoside, guar gum and water as main raw materials, solves the problems of resource waste, poor preservation quality and single function caused by the conventional mechanical egg preservation, and has the advantages of good antibacterial and preservative effect, convenience in operation, low cost and the like.

Description

technical field [0001] The invention belongs to the field of food preservation, and in particular relates to a humic acid egg preservation film and a preparation method and application method thereof. Background technique [0002] At present, there are many researches on egg cling film at home and abroad, but most of them only use paraffin, chitosan, polyvinyl alcohol, propolis, etc. to make coating agents, the effect is not very satisfactory, and the exploration of composite coating agents is rare. . There are also people who use vegetable volatile oil as a bacteriostatic agent for egg preservation, but the cost is relatively high. [0003] Humic acid is a high-molecular organic substance produced by the decomposition and transformation of animal and plant remains by microorganisms. It has good physiological activity, absorption, complexation, exchange and other functions, and can play a very good antibacterial effect. However, the use of humic acid for egg preservation h...
