Organic deoxidizer with participation of metal ions

Abstract

The invention provides an organic deoxidizer with participation of metal ions. The organic deoxidizer comprises the following components in percentage by weight: 20-50 percent of a vitamin C substance, 2-10 percent of a metal ion catalyst, 15-30 percent of water, 5-40 percent of a water-retaining agent and 5-20 percent of an alkaline substance. According to the rapid and efficient organic deoxidizer, the vitamin C substance is promoted to rapidly react with oxygen mainly under the participation of ferrous ions, iron ions and copper ions, and the oxygen in a package is removed within a relatively short time, so that the problems of low deoxidation speed, relatively high activated carbon consumption, high possibility of hydrolysis under a strong alkaline condition and the like for a currentcommercially available organic deoxidizer are solved.

Description

technical field [0001] The invention belongs to the field of deoxidizers, and in particular relates to an organic deoxidizer in which metal ions participate. Background technique [0002] Deoxidizers, also known as deoxidizers and oxygen absorbers, can absorb oxygen and slow down the oxidation of food. Deoxidizers generally use iron powder as the basic raw material. The principle of action is that iron powder is oxidized into iron hydroxide with the participation of oxygen and water. Applied in general food, it can quickly remove free oxygen in the packaging, keep the food in an anaerobic environment, inhibit aerobic microorganisms, prevent oxidative rancidity, and achieve the purpose of maintaining food quality and extending shelf life. [0003] However, after the iron-based deoxidizer removes the oxygen in the packaging or container, the volume of the gas in the packaging container decreases, and the internal pressure decreases. Under the influence of the external atmosph...

AI Technical Summary

Problems solved by technology

However, this technical solution has the following defects: first, it needs the participation of strong bases such as sodium hydroxide and calcium hydroxide, and strong bases can cause the hydrolysis of vitamin C substances, thereby affecting the quality of the deoxidizer; second, the amount of organic deoxidizer Large and weak oxygen absorption capacity, it takes more than 4 days for 8g of organic deoxidizer to remove all the oxygen in a 50mL airtight container; third, the deoxidizer material can be used only after drying, that is, it needs to absorb water from food. play a role in deoxygenation

However, according to the patent, the oxygen concentration becomes 0.3% after 15 days of deoxidation, and the deoxidation speed is too slow; in addition, due to the relatively large amount of activated carbon, the deoxidizer may cause exothermic heat during the batching or production process, and more activated carbon powder may cause During the production process, the deoxidizer is included in the material, which affects the product quality

[0006] To sum up, the organic deoxidizers in the prior art have the following disadvantages: one is that the alkaline substance is too alkaline or the dosage is too large, which may cause the organic deoxidizer to hydrolyze, thereby affecting the deoxidation function; the other is that the existing organic deoxidizers deoxidize The speed is relatively slow, and it takes a long time to remove the oxygen in the package; the third is to rely on activated carbon as an oxygen adsorbent, although it can accelerate oxygen absorption, but in the specific production process, it will cause the deoxidizer to be trapped and cannot complete automated production ; Fourth, the large amount of activated carbon used in the production process will cause the deoxidizer to generate heat, resulting in energy loss of the deoxidizer
