Description
Technical Field
The invention relates to a preparation method of a composite food deoxidizer, belonging to the technical field of preparation of deoxidizers.
Background
When people develop food production and food processing, food preservation is highly regarded. In order to achieve the purposes of preserving and preserving food and prolonging the shelf life of food, people adopt various preservation technologies, such as refrigeration, irradiation and the like, but the most convenient and economic technology adopts methods of deoxidizing agent preservation and the like. It removes oxygen in a closed container in a short time through chemical reaction to make the food in an anaerobic state, effectively controls the growth of microorganisms such as bacteria, mould and the like, prevents oil oxidation, thereby effectively keeping the color, the fragrance and the taste of the food, preventing nutrient substances such as vitamins and the like from being damaged by oxidation and prolonging the shelf life of the food.
the deoxidizer can be classified into an organic matrix deoxidizer and an inorganic matrix deoxidizer. The organic matrix deoxidizer includes enzymes, ascorbic acid, etc. The ascorbic acid is a reducing agent, under the condition of oxygen, the copper ion is used as a catalyst, the ascorbic acid can be oxidized or dehydrogenated, so that the oxygen in the environment is removed, the method is commonly used for removing the oxygen in the liquid food, the method is one of the currently used deoxidizing agents with higher safety, the enzyme-based deoxidizing agent is commonly used for oxidizing alcohol with glucose, and the aim of deoxidizing is achieved by using the oxygen consumed when the glucose is oxidized into the gluconic acid. The inorganic matrix deoxidizer is reduced iron powder, which is oxidized into iron hydroxide in the presence of oxygen and water vapor. The iron-based deoxidizer commonly used at present has the widest application range, is easy to obtain raw materials, low in cost and high in safety, generally takes iron powder as a basic raw material, and is widely applied to various foods such as wet bread flour, wet noodles, wet vermicelli, wet snacks, semi-dry fish products and the like. However, the prior iron-based deoxidizer has the problems of poor low-temperature deoxidation effect, high moisture regain after use, low oxygen absorption rate, poor fresh-keeping and anti-corrosion effects and the like.
Disclosure of Invention
The technical problems to be solved by the invention are as follows: aiming at the defects that the prior iron series deoxidizer has poor low-temperature deoxidation effect, high moisture regain after use and low oxygen absorption rate and causes poor fresh-keeping and anti-corrosion effects, the invention provides a method for preparing a composite food deoxidizer by using montmorillonite as a filling material, providing platinum ions through a chloroplatinic acid solution, enabling the montmorillonite to load the platinum ions, melting and coating the platinum ions at high temperature, increasing the catalytic efficiency, generating magnesium nitride through burning magnesium powder in nitrogen, melting the magnesium nitride on the surface of the filling material, oxidizing humic acid with hydrogen peroxide, sulfonating the oxidized humic acid through sulfur trioxide, increasing the absorption of sulfur dioxide and ammonia gas, and finally mixing the magnesium nitride and water with iron powder and sodium hydrosulfite to prepare the composite food deoxidizer, wherein the magnesium nitride and water are used for generating magnesium hydroxide and ammonia gas under the catalysis of platinum, the ammonia gas is absorbed through the treated humic acid, and the sulfur dioxide generated by the reaction of the ammonia gas and the sodium hydros, the method produces ammonium bisulfate in the water environment, and the ammonium bisulfate rapidly reacts with oxygen to generate ammonium sulfate, so that the iron powder is protected during deoxidation, and the principle of improving the deoxidation efficiency is adopted, thereby effectively solving the problems of poor low-temperature deoxidation effect, high moisture regain and low oxygen absorption rate of the traditional iron-based deoxidizer, which result in poor fresh-keeping and anti-corrosion effects. The preparation steps are simple, the obtained composite food deoxidizer has a good low-temperature deoxidizing effect, the moisture regain can be effectively reduced after the deoxidizer is used, the oxygen absorption rate is improved, and the deoxidizer has good fresh-keeping and anti-corrosion effects.
In order to solve the technical problems, the invention adopts the following technical scheme:
(1) According to the mass ratio of 1:3, taking montmorillonite and chloroplatinic acid solution with the mass fraction of 10% into a container, placing the container into an ultrasonic oscillator for oscillation for 30-40 min, filtering, placing filter residues into a calcining furnace, setting the temperature to be 1800-1900 ℃, calcining for 1-2 h, cooling to room temperature along with the furnace, taking out calcined substances, placing the calcined substances into a pulverizer for pulverization, sieving with a 200-mesh sieve, and collecting sieved particles;
(2) uniformly mixing the sieved particles and magnesium powder with the mass of 10-15%, putting the mixture into an electric melting furnace, using nitrogen for protection, setting the temperature to be 810-850 ℃, preserving heat for melting for 40-50 min, naturally cooling to room temperature, taking out the molten mixture, putting the molten mixture into a vacuum ball milling tank, adding steel balls with the diameter of 50mm according to the ball-to-material ratio of 20:1, carrying out ball milling for 40-50 min at the speed of 150r/min, and collecting ball milled materials for later use;
(3) Taking 45-50% of hydrogen peroxide with the mass fraction of 10%, 3-5% of sulfur trioxide and the balance of 300-mesh humic acid according to the mass percentage, putting 300-mesh humic acid and 10% of hydrogen peroxide with the mass fraction into a flask, stirring for 50-70 min at 150r/min, then adding sulfur trioxide, stirring for reaction for 4-5 h, filtering, washing filter residues with distilled water until the washing liquid is neutral, then putting the filter residues into an air dryer for air drying, and collecting air-dried substances;
(4) Weighing 40-50 parts by weight of the ball milling material for standby in the step (2), 30-35 parts by weight of the air drying material, 28-33 parts by weight of iron powder, 12-13 parts by weight of sodium chloride and 8-10 parts by weight of sodium hydrosulfite, sequentially putting the materials into a grinding mill, grinding the materials at 200r/min for 30-40 min, collecting the grinding materials, putting the grinding materials into a sealing bag, and sealing and storing the sealing bag to obtain the composite food deoxidizer.
The application method of the invention comprises the following steps: the composite food deoxidizer prepared by the invention is packaged and then placed in a food packaging bag, the placing amount of the deoxidizer is controlled to be 1.2-1.3% of the food quality, then the food packaging bag is placed at-8-40 ℃, after 3-4 days, the oxygen absorption rate is detected to be 71.6-82.3%, the growth of microorganisms such as bacteria, mold and the like in food can be effectively controlled, grease oxidation is prevented, the color, the fragrance and the taste of the food can be effectively maintained, nutrient substances are prevented from being damaged by oxidation, the moisture regain of the food after being stored for 2-3 months is 5.3-7.8%, and the composite food deoxidizer is worthy of popularization and use.
compared with other methods, the method has the beneficial technical effects that:
(1) The preparation steps are simple, the obtained composite food deoxidizer has a good low-temperature deoxidizing effect, and the oxygen absorption rate is improved by 26-35% compared with that of the traditional deoxidizer;
