Dual-Absorption Food Oxygen Absorber

The Dual-Absorption Food Oxygen Absorber is an innovative food preservation product that breaks through the limitation of traditional oxygen absorbers, which only absorb oxygen. It utilizes a special chemical formulation to achieve the dual functionality of simultaneously absorbing both oxygen and carbon dioxide. The core technology of this type of oxygen absorber lies in its formulation, which contains components that react with oxygen and components that adsorb carbon dioxide. Once the oxygen absorber is placed inside a sealed food package, these active ingredients react with the gases inside, effectively reducing the concentration of both oxygen and carbon dioxide within the package.

Compared to traditional oxygen absorbers, the working mechanism of the dual-absorption oxygen absorber is more complex and targeted. Taking coffee preservation as an example, the dual-absorption oxygen absorber specifically developed for coffee can reduce the oxygen concentration to an extremely low level (below 0.1%) within 24 hours, while simultaneously adsorbing the carbon dioxide naturally emitted by the coffee, creating a suitable micro-environment inside the package. While absorbing carbon dioxide, this oxygen absorber also enhances package sealing by creating a negative pressure environment, making the degassing valve seal more tightly, thus better preserving the product’s original flavor and quality.

For specific foods like dried red dates, aside from being susceptible to oxidation due to oxygen during storage, carbon dioxide concentrations exceeding 5% can also accelerate the softening and browning process of the dates. The dual-absorption oxygen absorber fundamentally solves the texture change problem in dried red dates caused by high carbon dioxide concentrations by simultaneously removing both gases. It also effectively inhibits the oxidative loss of vitamin C and microbial growth, comprehensively extending the food’s shelf life.

I. Preservation Application in Coffee Products

In the field of coffee preservation, the dual-absorption oxygen absorber plays an irreplaceable role. Coffee beans produce a large amount of carbon dioxide after roasting, which can accumulate inside the package, causing bag inflation and even affecting the coffee’s flavor. The dual-absorption oxygen absorber, specifically developed for coffee preservation, combines the functions of “high-speed deoxygenation” and “carbon dioxide adsorption,” working simultaneously to prevent coffee oxidation. After placing this oxygen absorber inside the coffee package, it can completely remove oxygen within 24 hours, thereby maintaining the freshest original taste of the coffee.
The aromatic compounds in coffee are extremely complex and susceptible to oxidation. The dual-absorption oxygen absorber effectively protects these precious volatile aromatic substances by creating a low-oxygen environment, allowing the coffee to maintain its unique flavor characteristics for an extended period. For different forms of coffee products, such as whole bean, ground coffee, and instant coffee, the dual-absorption oxygen absorber can provide corresponding protection solutions based on their characteristics, comprehensively enhancing the shelf life and quality stability of coffee products.

II. Preservation Solutions for Dried Red Dates and Other Agricultural Products

Dried red dates face various quality deterioration issues during storage: besides high humidity causing fermentation, spoilage, and mold, they are also prone to pests such as Indian meal moths. More peculiarly, carbon dioxide levels exceeding 5% accelerate the softening and browning of dried red dates. Addressing these characteristics of dried red dates, the dual-absorption oxygen absorber provides a comprehensive solution: by simultaneously removing oxygen and carbon dioxide, it effectively delays the processes of softening, browning, and vitamin C loss in dried red dates.
In practical applications, placing the dual-absorption oxygen absorber with dried red dates in a packaging container with low oxygen transmission rate and sealing it can significantly extend the preservation period of the dates. Compared to using ordinary oxygen absorbers, the dual-absorption oxygen absorber better maintains the original texture and color of dried red dates, preventing quality degradation caused by carbon dioxide accumulation. Furthermore, the dual-absorption oxygen absorber possesses a certain moisture absorption capacity, helping to control humidity within the package and further inhibiting the growth and reproduction of microorganisms.
