Moisture-proof deoxidizing agent for foodstuff

Abstract

The invention discloses a moisture-proof deoxidizing agent for foodstuff, and belongs to the technical field of a deoxidizing agent for foodstuff. The moisture-proof deoxidizing agent for the foodstuff disclosed by the invention comprises the following components in parts by weight: 90-110 parts of iron powder, 5-15 parts of calcium chloride, 5-15 parts of activated carbon and 20-40 parts of auxiliary material, wherein the auxiliary material is attapulgite and montmorillonite, and the mass ratio is (4-6) to (4-6). The moisture-proof deoxidizing agent for the foodstuff disclosed by the invention has a long-term deoxygenization effect, and the antioxidant effect of an easy-to-oxidize food can be significantly improved. Meanwhile, the original oxygen absorbing performance still can be kept under a high-humidity condition, and the moisture-proof deoxidizing agent also has an auxiliary dehumidifying effect, and is significant in effect, simple in preparation technology, convenient to add and use, high in safety, lasting in action, low in production cost, applicable to preservation of various foods, and beneficial to popularization and application.

Description

technical field [0001] The invention belongs to the technical field of deoxidizers for food, and relates to a moisture-resistant deoxidizer for food. Background technique [0002] Deoxidizer is an additive that can absorb oxygen and slow down the oxidation of food. Deoxidizers can effectively inhibit the growth of mold and aerobic bacteria, prolong the shelf life of food, and also play a very good role in preventing oil rancidity, oxidative browning of meat, and loss of vitamins in food. [0003] There are many types of deoxidizers, and iron-based deoxidizers are widely used at present. The iron-based deoxidizer is based on the oxidation-reduction reaction of iron powder, and this reaction needs to be carried out easily in the presence of moisture, which is actually an electrochemical corrosion reaction process. The oxygen removal mechanism of the iron-based deoxidizer can be expressed by the following chemical reaction equation: [0004] Fe+2H 2 O→Fe(OH) 2 +H 2 ...

Problems solved by technology

Chinese patent (application number: 87105536) discloses an iron-based desiccant containing deliquescent substances and additives for absorbing gas and moisture. The specific preferred components are 1 weight part of iron powder, 0.5 parts of calcium chloride, Sodium 1.0-1.5, sodium sulfite 0.7-1.0, activated carbon 0.3-0.6, because the deoxidizer contains calcium chloride, a highly hygroscopic and deliquescent substance, under high humidity conditions, calcium chloride absorbs too much water and easily causes Deliquescence can easily affect the quality of deoxidized preserved food

[0009] In order to enable the deoxidizer to be used in a high-humidity environment and maintain oxygen absorption and energy absorption, a Chinese patent (application number: 200580052008.1) provides a deoxidizer composition containing 100 parts by weight of iron powder, 0.01-20 parts by weight of Metal halide and 0.01-5 parts by weight of water repellent (metal soap, mainly alkali metal or alkaline earth metal salt of fatty acid); when the deoxidizer is used under high humidity, water will form water droplets on the deoxidizer composition , will not cover the deoxidizer itself, so it will not affect the deoxidation performance of the deoxidizer, but because the iron-based deoxidizer must have enough water to fully react, the deoxidation performance will be greatly reduced in the case of less water, and at low When used in a humid environment, the effect is even worse
