Coffee Capsule

Less harmful than alternative coffee-brewing methods

According to the lead author of a new paper published in the Journal of Public Health, brewing coffee in a pour over method is less harmful than other methods. However, if you want more than two cups of coffee, you should opt for an alternative method. Also, be sure to stock up on pour over filters if you want to make more than two cups of coffee. Otherwise, you won’t be able to satisfy your caffeine fix!

Variety of flavours

Coffee capsules can be bought in a variety of flavours, each with its own distinctive character. Pure Origine coffee capsules contain single-origin beans, each with a distinct flavor. Ethiopian coffee, for example, has notes of wood and florality while Indian coffee has nutmeg, cloves, and cocoa notes. The flavor of coffee from Colombia is intense and reminiscent of cranberries, while that from Brazil has a toasted grain taste.

Extraction method

The process of making liquid coffee extract from coffee grains in a capsule is known as a coffee capsule extraction method. It requires a specific level of extraction time, usually 180 seconds, and requires that the coffee grains retained at least 60% of their initial height at the end of the extraction process. The coffee capsule is typically made of a cup-shaped body with a cylindrical rim and a sealed upper wall member. The upper wall member can be a lid or a membane with an inlet and outlet.

To investigate the effects of different variables on extraction time, multiple regression analysis was used to identify multivariate correlations between the coffee weight and various capsule parameters. The analysis determined that TDS and Q100um are important parameters affecting the extraction time. In addition, higher pressure in the capsule was associated with a longer extraction time.

In the study, 43 different commercial capsule coffees were evaluated. Each of them exhibited different levels of aroma and flavour. This is expected, given that different types of coffee are processed differently. Also, different blends and roast levels affect the overall flavour of each coffee. Another parameter considered was the body of the coffee. The TDS (total dissolvable solids) measured in the coffee extract was higher for roasted coffee than for light coffees.

Compostability

Coffee pods are one of the most popular types of disposable coffee products. While they are convenient, they often end up in landfills. While coffee pods can be composted in a commercial composting facility, it takes at least twelve to sixteen weeks. While home composting is perfectly safe, the process takes much longer.

The first step to composting coffee capsules is to fill the capsule with a compostable material. These capsules are usually packed in compostable film to preserve their organoleptic properties. These new materials have been added to coffee capsule packaging since January 2020. The companies responsible for bringing this technology to market have created packaging for private label brands, vending machines, and HoReCa groups.

Composting coffee capsules can also help reduce waste in landfills. However, the process is expensive, since companies have to develop new packaging for the coffee capsules. Compostable materials are much more expensive than conventional plastics, so companies can’t afford to pass the costs on to the consumer. For instance, Wolfgang Puck’s new coffee pods will cost $0.60 each, and the Biodegradable Coffee Company’s coffee capsules will cost $0.53.
