What is the function of the inner coating of the coffee bean metal pails
The inner coating of the coffee bean tinplate metal pail has the following important functions:
1: Protect coffee bean quality
Prevent oxidation: Coffee beans are rich in oils. These oils are prone to oxidation when exposed to oxygen, causing the flavor of the coffee beans to deteriorate. The inner coating can act as a barrier to reduce the contact between oxygen and coffee beans, effectively delaying the oxidation process of coffee beans. For example, some coatings with high barrier properties can significantly reduce oxygen transmission, allowing coffee beans to retain their fresh flavor for a longer period of time.
Block moisture: Humidity is one of the key factors affecting the quality of coffee beans. If coffee beans absorb too much water, it can cause them to become moldy or change the flavor after roasting. The coating can prevent external moisture from entering the coffee bean tinplate metal pail and maintain a relatively dry environment inside the metal pail. Especially in humid environments, coated coffee bean barrels can better protect coffee beans from moisture.
2: Keep the flavor pure
Prevent odor absorption: Coffee bean tinplate metal pail may be exposed to various odor sources, such as surrounding spices, chemicals, etc. The inner coating can prevent coffee beans from absorbing these odors. It is like an isolation layer to ensure that the original flavor of coffee beans is not disturbed by external odors. For example, in places with complex environments such as warehouses or kitchens, the coating can prevent coffee beans from being contaminated with the smell of other items.
Reduce flavor substance leakage: At the same time, the coating can also prevent the flavor substances of coffee beans from seeping into the metal pail wall. Some flavor components in coffee beans, such as volatile aroma compounds, may react with or be absorbed by the barrel wall material. With the coating, these flavor substances can be better retained inside the coffee beans, keeping the coffee flavor rich and pure.
3: Enhance the durability of the body of tinplate metal pail
Prevent corrosion: If the coffee bean metal pail is made of metal, such as tinplate, the inner coating can prevent the acidic components or moisture in the coffee beans from corroding wall of metal pail. Corrosion not only damages the body of metal pail, but may also cause metal ions to dissolve and contaminate the coffee beans. The coating can form a protection between the barrel wall and the coffee beans, extending the service life of the coffee bean tinplate metal pails.
Wear protection: During the frequent use of coffee beans, the barrel wall may be subject to friction and collision. The inner coating can play a certain wear-resistant role, reduce the wear of the barrel wall, and maintain the integrity of the coffee bean barrel. For frequently used coffee bean barrels, this can ensure that they always provide good storage conditions for coffee beans.
