Chips manufacturers flush bags of chips with gases like nitrogen to displace the oxygen inside the packaging. By reducing the oxygen content, they inhibit the oxidation of the fats and oils present in the chips, thus extending their shelf life ...

Air-tight containers create a barrier that limits the exposure of food to oxygen in the air. Since oxygen is a key factor in the oxidation process, minimizing its contact with fats and oils helps slow down the oxidation reaction, preserving ...

Antioxidants are substances added to food containing fats and oils to prevent or slow down oxidation. They work by scavenging free radicals, which are reactive molecules that initiate oxidation reactions, thereby preserving the freshness and quality of the food.

When fats and oils undergo oxidation, they become rancid, resulting in changes in their smell and taste. This process alters the quality of the food product, making it undesirable for consumption.

Corrosion of iron is a serious problem because it leads to structural weakness and degradation of iron-based objects, requiring significant financial resources for repairs and replacements. Various preventive measures, such as coatings, galvanization, and alloys, are employed to mitigate corrosion ...

Corrosion can damage various objects made of metals, including car bodies, bridges, iron railings, ships, and other structures. It poses a significant problem, especially for iron-based materials.

Corrosion is the process by which metals are gradually destroyed by substances such as moisture, acids, and salts in their surrounding environment. It occurs through chemical reactions that degrade the metal’s surface over time.

Copper develops a green coating, known as patina, while silver forms a black coating when corroded. These coatings are examples of corrosion and affect the appearance of the metals.

The process is commonly known as rusting of iron, wherein iron articles develop a reddish-brown powder on their surface when exposed to moisture and oxygen.

Oxidation-reduction reactions involve the simultaneous occurrence of oxidation and reduction processes. The term “redox” is derived from the words “reduction” and “oxidation,” reflecting this dual nature of the reactions.
