〔保存結果〕
The present invention relates to a packaging method that allows roasted regular coffee to be stored for a long period of time. In general, food preservation methods include vacuum packaging and gas exchange packaging. Furthermore, by using chemicals such as oxygen absorbers and gas exchange agents, the former absorbs and removes oxygen from the air inside the packaging, while the latter There is a method to maintain the freshness of food by replacing the oxygen in the air inside the package with carbon dioxide gas, etc. Among food products, when regular coffee is left in the air after roasting, the oil and fat components in the coffee beans are oxidized by the oxygen in the air, and the aroma components are dissipated, reducing its freshness. Additionally, regular coffee (including roasted and ground coffee) releases carbon dioxide gas. Based on the above, current regular coffee is often packaged with inert gas (mainly nitrogen gas), but as deoxidation is incomplete, it is not possible to obtain sufficient effects. do not have. Furthermore, since carbon dioxide gas is generated from regular coffee, the package expands, which not only looks bad but also causes problems such as the packaging bag breaking. Therefore, the present invention maintains the freshness of regular coffee by enclosing a chemical that has the function of removing oxygen from the regular coffee package and at the same time absorbing carbon dioxide gas generated from the coffee. This is a packaging method that prevents the expansion of The present invention will be explained in detail below. The present invention uses ferrous compounds such as ferrous sulfate and ferrous chloride, alkali metal hydroxides such as sodium hydroxide and calcium hydroxide, or alkaline earth metal hydroxides, and alkali compounds such as sodium carbonate and potassium carbonate. When packaging regular coffee, a package containing a chemical containing metal carbonate and additives such as activated carbon and silicic acid anhydride is sealed together with the coffee in a substantially non-breathable packaging material or container to prevent oxygen and carbon dioxide gas. This is a packaging method that is characterized by absorbing water and maintaining freshness. It is also possible to add a carbon dioxide absorbent made of an alkali metal or an alkaline earth metal as one component of the drug. Hereinafter, the reaction of the present invention will be explained in detail. For example, the composition ratio of a drug consisting of additives such as ferrous sulfate, calcium hydroxide, sodium carbonate, and activated carbon is as follows. FeSO 4・7H 2 O 1 part by weight Ca(OH) 2 1 〃 Na 2 CO 3・10H 2 O 0.04 〃 Activated carbon 0.04 〃 First, ferrous sulfate heptahydrate and calcium hydroxide interact with oxygen in the air. reacts and absorbs oxygen. Calcium hydroxide is consumed in the oxygen absorption reaction, and the amount consumed is equivalent to the amount of ferrous sulfate heptahydrate. Further, carbon dioxide gas absorption is performed by combining calcium hydroxide and carbon dioxide gas and changing into calcium carbonate. The agent used in the present invention is characterized by using an alkali hydroxide compound in an amount equivalent to or more than the ferrous salt such as ferrous sulfate heptahydrate in order to absorb oxygen and carbon dioxide. Further, in the above composition, sodium carbonate decahydrate is added to initiate the reaction between ferrous sulfate and calcium hydroxide. Normally, the above reaction is initiated by moisture in the air, but since the content is regular coffee, the moisture in the air cannot be utilized, and the water activity of regular coffee is extremely low at approximately 0.3.
Moisture in the packaging cannot be utilized. In this sodium carbonate decahydrate, water out of the crystal water is released at 32°C, and 9 water is released at 35°C, contributing to the initiation of the reaction between ferrous sulfate and calcium hydroxide. Here, the separation of the water of crystallization from sodium carbonate decahydrate is carried out by the heat of reaction caused by ferrous sulfate, calcium hydroxide, and activated carbon, some of which exhibit an exothermic reaction. Next, these reactions will be explained using reaction formulas. [Oxygen absorption reaction] 2FeSO 4・7H 2 O＋2Ca(OH) 2 ＋H 2 O＋1/2O 2 →2Fe(OH) 3 ＋
2CaSO 4・2H 2 O+10H 2 O [Carbon dioxide absorption reaction] Ca(OH) 2 +CO 2 H 2 O --→ CaCO 3 +H 2 O As described above, it has oxygen absorption and carbon dioxide absorption functions used in the present invention. The drug utilizes a small amount of moisture in the air to cause an initial reaction, and the heat of the reaction causes the crystallization water of sodium carbonate decahydrate to be separated from the ferrous compound and alkali metal or alkaline earth. By adding free water to the hydroxide of a similar metal, it reacts with oxygen intermittently and absorbs oxygen. Then, the alkali metal or alkaline earth metal hydroxide further reacts with carbon dioxide gas and absorbs it. Therefore, even when used in foods with low water activity, such as regular coffee, the reaction is sufficient.
In addition, the water required to start the reaction can be the crystal water contained in the drug, and since no free water is added from the outside, there is no water transfer to regular coffee during storage, and regular coffee Without changing the moisture content during roasting of Yuler coffee,
It is possible to maintain freshness. The reaction mechanism of the drug used in the present invention has already been explained, and next, the composition ratio of each drug used in the drug will be explained. The agent used in the present invention is suitably 0.5 to 2.0 parts by weight of alkali metal or alkaline earth metal hydroxide and 0.01 to 0.1 part by weight of sodium carbonate decahydrate per 1 part by weight of the ferrous compound. , activated carbon, silicic anhydride, and the like are suitably added in an amount of 0.01 to 0.1 part by weight. Next, the packaging material used in the present invention is a substantially non-breathable material with an oxygen permeation rate of 100 c.c./m 2 ,
24hrs・atm or less, preferably 30c.c./m 2 , 24hrs・
There is no particular restriction on the amount of carbon dioxide permeation, as long as it is atm or less. When the above-mentioned drugs and regular coffee are sealed in a packaging material with an oxygen permeability of 100 c.c./m 2 and 24 hours/atm or less, the oxygen concentration inside the package decreases significantly, causing regular coffee to deteriorate due to oxygen. Furthermore, since the generated carbon dioxide gas is absorbed by the drug, the packaging bag does not expand or break, resulting in a packaging bag with a good appearance. Below, the effects of packaging regular coffee using a drug having the above composition will be explained based on examples. <Example> 200g of regular coffee was packaged under the following conditions and a storage test was conducted. [Packaging method according to the present invention] A drug consisting of 1 part by weight of ferrous sulfate heptahydrate, 1 part by weight of calcium hydroxide, 0.04 part by weight of sodium carbonate decahydrate, and 0.04 part by weight of activated carbon is packaged in open-pore polyethylene ( 30μ)/high-quality paper (45g/m 2 ), filled in a bag with a size of 50 x 70m/m, and sealed.
This was sealed and packaged together with 200 g of regular coffee beans in a 200 x 300 m/m bag made of a laminate of biaxially stretched nylon (12μ)/polyethylene (60μ). [Conventional Packaging Method] 200 g of regular coffee beans were packed as they were in a 200 x 300 m/m bag made of a laminate of biaxially stretched nylon (12μ)/polyethylene (60μ) and filled with nitrogen gas.
