Talk about wine packaging influenced by the influence of trace oxygen on wine quality

Nowadays, wine has become a new trend of wine consumption because of its nutrition and key-keeping. More and more people choose to drink wine. At the same time, the requirements for wine are also more demanding. It is required that wine not only have the function of nutrition and key-keeping, but also have good taste and color. As a result, the research work on wine nutrition, color, texture, and aroma has been widely carried out in enterprises and research institutions; the focus of these studies is on the role of oxygen in wine production and storage and the control of the penetration of oxygen in wine packaging (bottles). Quantity analysis and testing. How does oxygen affect the quality of wine and how can one reasonably control the oxygen throughput of wine packaging? The author hopes to discuss the issue of "the influence of trace oxygen on the quality of wine in wine packaging inspection" and colleagues in the wine industry.

Oxygen plays an important role in wine storage and shelf display. The trace amount of oxygen promotes the polymerization of tannins, which makes the color of the wine brighter and more stable in color, and at the same time makes the wine fuller and reduces the green taste of the new wine. In addition, it also contributes to the volatilization of aromatic substances (aromatic odors) in wine, making the fruit more intense and rich. However, excessive oxygen can cause the wine to lose its nutrition and taste and even deteriorate due to excessive oxidation. The wine packaging is mainly based on glass bottles. Although oxygen can not pass through the glass material, the bottle body is not integrated with the bottle cap. Even if the bottle body and the bottle cap have high barrier properties, oxygen will still pass through cork stoppers or gaskets. Into the glass inside, so the detection and control of the amount of oxygen penetration has fallen to the bottle sealing part of the oxygen permeability test up.

The United States ASTM F1307 standard specifies the air permeability performance test requirements for containers (including bottle packaging). The TOY series container/film oxygen permeability tester produced by Labthink (pictured below) is designed and manufactured in accordance with this standard. Excellent Solved the need for wine companies to test the oxygen permeability of wine packaging.

The encapsulation structure of wines is generally in the form of crown caps, gaskets and cork stoppers. Usually people think that this type of packaging can completely block out oxygen without worrying about the oxygen permeability of the product after packaging, let alone worry about the loss of flavor and oxidative deterioration caused by the influx of excess oxygen.
