Description

Control Valve Caps for Coffee Bean Packaging}

The present invention relates to a control valve cap for a coffee bean packaging body, and more specifically, a coffee bean capable of blocking the inflow of air while smoothly discharging carbon dioxide emitted when the coffee bean is fresh after roasting to the outside of the packaging body. By providing a control valve cap in the form of a check valve attached to the package, when the coffee beans are fresh, the cap is opened to induce gas discharge, and in order to prevent further oxidation, the cap is locked to prevent the inflow of external air. It relates to a control valve cap for a new type of coffee bean packaging body that can maintain the freshness by controlling the freshness of the packaged coffee bean so as to delay the acidity rate of the coffee beans by physically blocking it.

In general, coffee is roasted at a high temperature, so it undergoes a certain sterilization process. In this process, coffee beans sold in the market are not easily decomposed compared to other foods because the moisture of the green beans evaporates hardly. Although the deadline is indicated as 1~2 years, this is a period that can be distributed on the market, but it is not a period of good coffee beans. Specifically, there may be a slight difference between the types of beans, but it is usually best to roast and drink between two days and two weeks later, and thereafter there is a phenomenon in which the aroma disappears and the taste deteriorates over time. Can be. This phenomenon is called the rancidity of coffee.

The rancidity refers to a process in which the fat and oil becomes acidic by the action of oxygen, moisture, heat, sunlight, bacteria, enzymes, etc. in the air, causing an unpleasant odor, and the taste deteriorates or changes color. Combined with and means that the scent disappears and the taste changes over time.

As a factor of rancidity, there is a change in the rate of rancidity depending on temperature and humidity. Whenever the temperature rises by 10°c, 2.3 scents are lost, and when the relative humidity is 100%, 3-4 days, when 50%, 7~ On the 8th, at 0%, rancidity begins from 3 to 4 weeks.

There are air packaging, vacuum packaging, valve packaging, nitrogen gas packaging, etc. in order to slow down the oxidation of coffee as described above. Among these, nitrogen pressure packaging is the longest on the storage surface, but nitrogen is used for the storage of coffee during storage. There is a problem in terms of freshness because it absorbs moisture and dries the coffee.

In order to drink coffee with good flavor without nitrogen pressure packaging as described above, there is a method of crushing and drinking beans immediately before extraction. Currently, commercially available coffee beans are sold in the range of 100 to 200 g, and as much as 500 g. 1 It can be said that the oxidation of coffee begins as air enters the inside of the package from the time the product is opened to eat the amount of ash.
