Problems solved by technology

The deoxidizing preservative has dual fresh-keeping functions of deoxidation and sterilization. Dimethyl fumarate has strong antibacterial and antifungal properties, but its pungent smell is too heavy, which has a significant impact on food flavor and is not suitable for industrial applications.

Embodiment 1

[0009] Example 1: Bactericidal dehydration and deoxygenation preservative as the main type of sterilizing and water-absorbing agent

[0010] The formula of the preservative is as follows: 55% iron powder, 4.0% activated carbon, 2.5% water-absorbing resin, 5% quicklime, 0.30% mixture of propyl p-hydroxybenzoate and ethyl p-hydroxybenzoate (NBJ), sodium bisulfite 1.25%, salt 2.95%, silica gel 25%, water 4%. This preservative is suitable for the preservation of dried seafood with relatively low salt and sugar content, such as shredded squid, fried sea crab, seaweed, seaweed, etc.; the preservation of dried fruits that need to control moisture, such as dried citrus slices, dried Navel orange slices, dried chrysanthemums, banana slices, etc.; wooden products and handicrafts that need to be protected against moths.

[0011] The preparation method of the above-mentioned antistaling agent is as follows: 1) fully mix sodium bisulfite and activated carbon, and then mix with iron powder...

Embodiment 2

[0012] Example 2: Deoxidation is the main type, and sterilization and water absorption are the auxiliary type of sterilization, dehydration and deoxygenation preservative

[0013] The formula of the preservative is as follows: 81% iron powder, 1.5% activated carbon, 2.5% water-absorbing resin, 0.5% quicklime, 0.05% mixture of propyl p-hydroxybenzoate and ethyl p-hydroxybenzoate (NBJ), sodium bisulfite 0.6%, salt 2%, silica gel 7%, and the rest is water. This preservative is suitable for dried fruit foods such as melon seeds, peanuts, torreya, walnuts, tea, etc., with excellent effect.

Embodiment 3

[0014] Example 3: Mainly water absorption, deoxidizing and sterilizing as auxiliary sterilizing, dehydrating and deoxidizing antistaling agent

[0015] The formula of the preservative is as follows: 65% iron powder, 1.5% activated carbon, 2.5% water-absorbing resin, 3% quicklime, 0.1% mixture of propyl p-hydroxybenzoate and ethyl p-hydroxybenzoate (NBJ), sodium bisulfite 0.9%, salt 2%, silica gel 21%, water 4%. This preservative is suitable for pickled and dried foods that tend to generate water vapor and contain more water during the preservation process, such as dried kelp.

Abstract

The invention discloses a sterilizing, dehydrating and oxygenating antistaling agent and its preparation method. Current oxygenating and antistaling agents have the double functions of oxygenating and sterilizing, but have heavy irritating odor, which greatly influences the flavor of the food, thus not suitable for industrial application. The antistaling agent of the invention is made up of the following materials in weight ratio: ferrous powder 55-81%, active carbon1.5-4.0%, absorbent resin0.5-2.5%, quick lime0.5-5%, the mixture of ethyl p-hydroxybenzoate and ethyl p-hydroxypropyl formate0.05-0.30%, hydrosulphite0.6-1.25% and the rest is silica gel. The invention integrates the functions of sterilizing, dehydrating and oxygenating and has good effects; the invention is strong in antibacterial action and light in odor, and hardly influences the flavor of the food, thus the invention is suitable for industrial application.

Description

technical field [0001] The invention relates to the field of antistaling agents, in particular to a sterilizing, dehydrating and deoxidizing antistaling agent and a preparation method thereof. Background technique [0002] Most of the deoxidizers currently used are based on the oxidation reaction of iron powder. This iron-based deoxidizer can be made into a bag and put into the package to reduce the oxygen concentration to 0.01%. It is generally required that 1g of iron powder can react with 300mL of oxygen. The oxygen permeability of the membrane is selected in an appropriate amount. Applied products include candy, dried seafood snacks, cooked meat products, rice cakes, pasta, cheese, dried vegetables. In addition to the bagged deoxidizer, a plastic label or various cards containing active iron powder are inserted into the package. Deoxidizers can effectively inhibit the growth of mold and aerobic bacteria, prolong the shelf life of food, and also play a very good role i...
