Tea and coffee Packaging: How to maintain the flavor of coffee beans in coffee packaging and ground coffee in drip coffee pouch?
Roasting coffee takes time, it takes effort, and it takes a lot of trial and error to release the flavor of the coffee. But after roasting, consumers can also feel the taste of coffee while drinking coffee, so tea and coffee packaging: how to maintain the flavor of coffee beans in coffee packaging?
How to maintain the flavor of coffee packaging beans?
1. That's what packaging is for. By using the right packaging materials, the aroma of coffee can be preserved enough to allow consumers to experience the flavor released by roasting.
2. Aroma is produced by volatile flavor compounds released during roasting and is often used to describe the taste or aroma of coffee beans.
3. Although the word "aroma" is usually associated with smell, when we drink coffee, we use it to describe the taste and aroma of coffee, generally referred to as "flavor", because the human tongue can only accurately locate some basic sensory tastes (such as bitter, sweet, and taste). So many of the more complex flavors in coffee are actually olfactory.
4. The taste of coffee is often used as an indicator of freshness. Simply put, the more aromatic compounds, the newer they are, the better they taste. The release of volatile components in coffee occurs naturally, but several environmental factors can speed up the process and make the aroma more volatile.
5. It is also a measure of freshness. Nel-thiol itself is a pungent chemical, but surprisingly in coffee it is used as an aromatherapy compound, hiding a bad smell.
6. When the ground coffee is directly exposed to the air, the methanol can be clearly felt within a day and 70% of the methanol is gone within three weeks." Exposure to oxygen or oxidation is one of the most common causes of coffee. In a podcast for the Fine Coffee Association, Tom from the University of Zurich said: "When I talk about chemical freshness, I'm talking about the aroma of the coffee, because the aroma of the coffee is in the beans that come from the coffee beans. Caused by volatile chemicals. Therefore, loss of chemical freshness means loss of aroma, oxidation or change."
7. Higher temperatures also speed up the oxidation process in coffee. Can accelerate the loss of some of the more sensitive volatile compounds in coffee, such as thiophenol or 2.3-diketone (usually associated with the sweetness of things like butter, caramel, and fruit).
8. So coffee beans are best stored in a cool, dry place, but not frozen. When thawed, the condensed water from condensation can damp the beans, degrade their quality and dissolve some volatile compounds. Preferably stored a few degrees above room temperature.
How can coffee packaging help save the taste of coffee?
1. Layers are a key part of effective packaging. "If you only have one layer, it's hard to keep the flavor of the beans. To protect against moisture, oxygen, sunlight, calories, etc. Different materials need to be used to protect the beans." He tested the effectiveness of aluminum as an inner layer for coffee packaging. He found that aluminum was the most effective barrier to oxygen compared to plastic, paper and other porous materials, and that it also protected against moisture.
2. The cost of using aluminum as the inner layer of packaging is very high. As a result, they are often replaced by metallic films (coated with a thin aluminum polymer film), and researchers and packaging manufacturers are also looking for more sustainable options. These options are easily degraded or reintroduced through biodegradation. This year, she told me, HondaPack coffee packing machine came out in fully recyclable multilayer packaging. This kind of packing only has two layers. Using fewer layers reduces the environmental impact of packaging and ultimately minimizes the carbon footprint of manufacturing.
3. After choosing the right packaging, the next step is filling and sealing. If the coffee package is not properly sealed, it will cause oxidation and accelerate the deterioration of taste.
4. Coffee packaging has several common sealing methods: Manual sealing machine, automatic filling and sealing, heat sealing Drip coffee packing machine, vacuum sealing machine, etc." .
5. The cost of sealing equipment varies from high to low. It is recommended to choose according to production and packaging factors. For example, a typical manual sealer may be difficult to use for multi-layer side corners.
6. To ensure freshness and ease of use, most consumers choose coffee packages that can be sealed. Yu told me that the sealing market in the market has zippers, Velcro zippers and other forms. Again, the best choice depends on the structure, size and personal preference of the coffee bag.
