preparation example Construction

[0030] The present invention also provides a kind of preparation method of food coating preservative, specifically implement according to the following steps:

[0031] Step 1, weighing, weighing the following components according to mass percentage: 5.0%-10.0% of grape seed essential oil or fennel essential oil; 0.5%-3.0% of ginger extract; 5.0% of glyceryl monocaprylate or hydrophilic laurate -10.0%; the rest is zein film raw material, the sum of the above mass is 100%;

[0032] Step 2. Prepare a mixed solution, fully mix and stir the zein film raw material and ginger extract, glyceryl monocaprylate or hydrophilic glyceryl laurate, dissolve and heat in ethanol at 60-80°C for 20 -40min, add one of grape seed essential oil or fennel essential oil and mix evenly to finally prepare a solution;

[0033] Step 3: Coating to form a film or drying to form a film. The above-mentioned prepared solution is coated on the food material or dried on a petri dish to prepare a food preservati...

Embodiment 1

[0038]Fully mix and stir 78% of zein film raw material, 2% of ginger extract, and 10% of glyceryl monocaprylate, dissolve in ethanol at 70°C, heat and stir for 30 minutes, add 10% of grape seed essential oil, mix well, and finally obtain solution A , coating solution A on fish meat A or drying a petri dish to prepare a food preservation film.

Embodiment 2

[0040] 78% of zein film raw material, 2% by mass of ginger extract and 10% of glyceryl monocaprylate were fully mixed and stirred, dissolved in ethanol at 70°C, heated and stirred for 30 minutes, and fennel essential oil with a mass concentration of 10% was added Mix evenly to finally prepare solution B, and apply solution B to fish meat B or dry a petri dish to prepare a food preservation film.

Abstract

The invention discloses a coating antistaling agent for food. The coating antistaling agent is composed of the following components by mass: 5.0 to 10.0% of grape seed essential oil or fennel essential oil, 0.5 to 3.0% of ginger extract and 5.0 to 10.0% of glycerol monocaprylate or hydrophilic laurin, with the balance being a zein film raw material, wherein the mass percents of the above-mentioned components sum to 100%. The invention also discloses a preparation method for the coating antistaling agent used for food. The coating antistaling agent can effectively delay food oxidation, inhibit moisture evaporation, exert bactericidal effect, prolong the shelf life of food and reduce cost and is an edible coating antistaling agent without toxicity and pollution.

Description

technical field [0001] The invention belongs to the technical field of storage and preservation of agricultural products, and in particular relates to a food coating preservative, and also relates to a preparation method of the food coating preservative. Background technique [0002] With the improvement of consumers' requirements for food quality and storage period, as well as the enhancement of environmental protection awareness, edible films made of natural biological materials have gradually become a research hotspot and development trend. Natural antioxidant and antibacterial preservatives refer to natural substances with antioxidant activity extracted from animals, plants or their metabolites. Compared with synthetic plastic wrap: Edible plastic wrap can be biodegraded without any pollution. They have the advantages of being natural, efficient, and low-toxic. Research and development of broad-spectrum, efficient and safe natural product preservatives has become one of...
