Coffee capsule inflated with nitrogen for freshness retaining

Abstract

The invention discloses a coffee capsule inflated with nitrogen for freshness retaining and belongs to the technical field of food. According to the coffee capsule inflated with the nitrogen for freshness retaining, ground coffee (2) is encapsulated in a degradable high-barrier-material cup body (1) through an imported full-automatic encapsulating production line, and the degradable high-barrier-material cup body (1) is sealed after being filled with the nitrogen (3) for freshness retaining. The degradable high-barrier-material cup body (1) is made of PLA and EVOH, wherein the PLA is an extractive, 'poly-lactose', of maize and can be degraded naturally, the EVOH is a copolymer high-crystallization body of ethylene-vinyl alcohol and can be degraded through burning, degradation products of the PLA are water and carbon dioxide, and degradation products of the EVOH are water and carbon dioxide. According to the coffee capsule inflated with the nitrogen for freshness retaining, the cup body is made of degradable high-barrier materials and is inflated with the nitrogen for freshness retaining, both freshness retaining and manufacturing are convenient, the size is small, the weight is low, generated waste can be treated easily, and the environment can not be polluted when the packaging cup body is discarded after coffee is drunk.

Description

Technical field:

[0001] The invention relates to the field of food technology, in particular to a cup body made of a degradable high-barrier material and a coffee capsule filled with nitrogen to keep fresh. Background technique:

[0002] At present, most of the coffee in the market is roasted coffee beans produced by semi-automatic or fully automatic machines. The coffee beans produced by this method have no effective measures to keep fresh, and the fresh-keeping period is short. After the coffee is produced, the coffee grounds need to be cleaned manually. . The coffee machine is large in size and expensive, and there are many environments and other auxiliary equipment for the coffee machine. There is an urgent need in the market for a novel coffee product that is convenient to keep fresh, easy to prepare, light in size, and easy to dispose of waste.

[0003] In addition, most of the current market uses high-barrier materials as food preservation packaging. Such materials ...
