My graduation thesis is related to this, but I study it as a fever.

The reason why you make hydrogen may be that the formula is wrong.

Or the dosage is too large.

deoxidizing agent

The types of deoxidizers are classified according to the components of the main agent.

(1) inorganic deoxidizer. The most widely used is iron-based deoxidizer. The deoxidation capacity of Fe(OH)3, 1 g iron is 300ml, which is equivalent to 1500ml air. The deoxidation effect is good and economical. The deoxidizers sold in the Japanese market include sand powder iron, refined iron powder and crude iron.

(2) Organic deoxidizer. For example, ascorbic acid has a good ability to remove oxygen; Under certain conditions, glucose alkaline substances produce a large number of decomposition products to remove oxygen.

According to the reaction type, we classified (1) high-moisture food types. After the deoxidizer and the food are sealed at the same time, the oxygen absorption of the oxygen absorber is generally carried out in the presence of water, and the water evaporated from the food is often used for oxygen removal.

(3) automatic absorption type. It can also be divided into quick-acting type, common type and slow-release type. Self-priming oxygen absorber keeps its own moisture and can react even if there is no water outside, changing the composition and dosage of oxygen absorber and changing the permeability of packaging materials. The reaction speed can be controlled from quick effect to slow effect.

Newly developed deoxidizer types Japan has developed deoxidizers suitable for various food properties, such as oil-resistant and moisture-resistant deoxidizers and special deoxidizers with various comprehensive capabilities.

The generated CO2-type oxygen accounts for 1/5 in the air, and the volume decreases 1/5 after deoxidation, which will lead to the contraction and decompression of food containers. Developing a functional deoxidizer that absorbs oxygen and produces CO2 equivalent to oxygen can avoid container shrinkage and prevent the deterioration of food quality. However, this model is not suitable for foods with high moisture content, because anaerobic bacteria can reproduce in the presence of CO2. When roasting coffee beans that absorb carbon dioxide, a large amount of carbon dioxide will be produced. When the package is sealed immediately after baking, CO2 will expand and even break the bag. When CO2 is absorbed and deoxidizer is absorbed, it is packaged immediately after roasting. This oxygen absorber can absorb 10 times of CO2 for a long time while absorbing oxygen, thus achieving the effect of anti-oxidation and fragrance preservation.

The ultra-small deoxidizer for small packaging has high performance, good water resistance and oil resistance, and is especially suitable for foods with high water content.

Flat film type is suitable for all kinds of bottled food, which is made according to the size of bottle cap and convenient for bottling. There is a tendency to gradually replace the dynamic type.

"Paper Pinhole Integration" Aesculus chinensis juice

T-type deoxidizer is a new product with independent reaction of iron-based materials and quick-acting s a oxygen content detector. Whether the packaging container is deoxidized can be confirmed by the pinhole tone of the paper, and measures can be taken in case of problems. This product has both deoxidation effect and quality management function.

The new product Aichelis is a new product based on oxygen absorber. In addition to the function of oxygen absorber, it can be divided into four types according to the use: trademark label type (with trademark label function), liner plate type (with cardboard as foil function), liner reinforced background type and new bag type. It also has new characteristics such as excellent microwave oven tolerance.

Membrane uses the heat and moisture of packaging film to absorb oxygen in the bag, which prevents the quality of food from deteriorating and discoloring after heating, improves product quality and storage resistance, and has a wide application range.
