Embodiment 1

[0033] The pretreatment method of embodiment 1 walnut kernel

[0034] 1 walnut preservative recipe

[0035] Said component A formula 1: walnut kernel antistaling agent formula, specifically consists of the following components in parts by weight: 2 parts of bamboo leaf antioxidant, 3 parts of tea polyphenols and 15 parts of water-soluble chitosan. The walnut fresh-keeping formula is fully mixed and dissolved with distilled water at a mass ratio of 5:100.

[0036] The A-component formula two: the walnut kernel antistaling agent formula, which specifically consists of the following components in parts by weight: 3 parts of bamboo leaf antioxidant, 7 parts of tea polyphenols and 5 parts of water-soluble chitosan. The walnut preservation formula is fully mixed and dissolved with distilled water at a mass ratio of 0.5:100.

[0037] Two processing methods

[0038] The pretreated walnut kernels are obtained by soaking walnut kernels in the antistaling agents prepared by formula 1 ...

Embodiment 2

[0040] The formula of component B described in embodiment two

[0041] The B component formula one: 40 parts of maltodextrin, 4 parts of guar gum, 25 parts of sorbitol, 8 parts of soybean protein isolate, and 0.8 part of gluco-δ-lactone.

[0042] The B component formula two: 60 parts of maltodextrin, 6 parts of guar gum, 35 parts of sorbitol, 12 parts of soybean protein isolate, and disodium edetate.

[0043] Other formula 1: on the basis of the B component formula 2, replace maltodextrin with carboxymethyl starch, hydroxypropyl starch, cross-linked starch, oxidized starch, phosphate starch and acetate starch.

[0044] Other formula 2: on the basis of the formula 2 of component B, replace guar gum with carrageenan, konjac gum, xanthan gum, gellan gum, sodium alginate and locust bean gum.

[0045] Other formula 3: on the basis of the B component formula 1, replace sorbitol with soybean oligosaccharides, mannitol, trehalose and lactitol.

[0046] Other formula 4: on the basis ...

Embodiment 3

[0047] Embodiment Sanhechuan peach slice packaging bag

[0048] The peach slices are packed into a Hechuan peach slice packaging bag, a deoxidizer is added, and sealed and stored. The Hechuan peach slice packaging bag is made of high barrier material and light-shielding material / light-proof material.

[0049] Preferably, the Hechuan peach slice packaging bag is a composite packaging bag made of 4-10 layers of high-barrier material and light-shielding material / light-shielding material, the high-barrier material is composed of ethylene-vinyl alcohol copolymer, and the light-shielding material is aluminum foil , The light-shielding material is all aluminum.

[0050] For details, please refer to the article "Structure and Properties of Multilayer Co-extruded High Barrier Films" published by Jia Zhige in "China Packaging News".

Abstract

The invention belongs to the field of food freshness keeping, and particularly relates to a special composite preservative for walnut cake. The special composite preservative comprises antioxidant of bamboo leaves, tea polyphenol, water-soluble chitosan, modified starch, food gum, functional sweeteners, an emulsifying agent, a chelating agent, natamycin and a rosemary extract. The application method comprises the steps that the walnut preprocessed by the preservative prepared by a component A is used as the walnut raw material of the walnut cake, a component B is fully mixed with revived powder of the walnut cake and then stewed into cake, 0.5 to 1% of alcohol by mass percentage in a component C is sprayed on the surface of the walnut cake after the sewing or before slicing or packaging, and then the walnut cake is stored for 60 days at natural room temperature. Compared with a reference substance, Hechuan walnut cake has the advantages that more than 85% of peroxide value is reduced, more than 85% of acid value is reduced, more than 90% of total clump count is reduced, and less than 15% of water loss ratio is achieved.

Description

technical field [0001] The invention belongs to the field of food preservation, in particular to a preservation process of peach slices.
