Description

  The present invention relates to a granular food packaged by packing, for example, a granular food product such as peanut or almond that is hermetically stored in a storage bag body in a state where it can be stored for a long period of time.

  Currently, many nuts such as peanuts and almonds sold in Japan are processed and manufactured overseas (for example, China and Vietnam) where labor costs are low.

  Conventionally, nuts such as peanuts and almonds have been processed and stored in a sealed bag made of synthetic resin with gas barrier properties together with an oxygen scavenger, and further stored in a box such as a cardboard box. Being transported.

  However, in the conventional storage form as described above, the oxygen concentration in the bag body in which nuts are sealed and stored can be suppressed to only about 3%. Therefore, oxidation of nuts in the bag body during transportation and storage is possible. As the oxidation progresses gradually, the flavor and freshness (freshness) are lost due to the progress of the oxidation, and the taste is lacking.

  Furthermore, in this conventional storage form, when a sharp-shaped object such as peanut or almond is stored, the oxygen remaining in the bag is absorbed by the enclosed oxygen scavenger, and the bag body is absorbed by this residual oxygen absorbing action. When the bag body is in close contact with the stored item due to shrinkage (shrinking), the sharp part of the stored item pierces and a pinhole is formed in the bag body, and a large amount of oxygen enters from the outside through this pinhole, There has also been a problem that the progress of oxidation is further accelerated and the taste is further impaired.

  The present invention has been made in view of such problems as described above, and oxygen hardly enters the bag body in which the granular food is sealed and stored during transportation and storage, and the bag body is almost oxygen-free. It is an object of the present invention to propose an innovative bag-packed granular food that is maintained in a state and maintains good flavor and freshness immediately after processing without oxidation of the granular food and can be eaten deliciously.

It is explanatory drawing which shows the manufacture procedure (storage packing procedure) of a present Example.

  An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

  Residual oxygen is absorbed and stored in the bag of the inner storage bag body 4 in which the protective bag body 3 storing the granular food 1 is hermetically stored, together with the oxygen absorbing action of the first oxygen scavenger 2 stored together with the granular food 1. The granular food 1 is in a low oxygen state (substantially oxygen-free) that is difficult to be oxidized.

  Conventionally, even if such a low oxygen state once occurs, oxygen that permeates and penetrates the bag gradually increases the oxygen concentration in the bag, and the oxidation of the granular food that is hermetically sealed gradually progresses. And the freshness is lowered and the quality is lowered.

  In this respect, in the present invention, the inner storage bag body 4 in which the protective bag body 3 storing the granular food 1 is hermetically stored is hermetically stored in the outer storage bag body 6 having gas barrier properties together with the second oxygen scavenger 5. The space between the inner storage bag body 4 and the outer storage bag body 6 outside the inner storage bag body 4 in which the protective bag body 3 storing the granular food 1 is hermetically sealed is stored in the second oxygen scavenger 5. Residual oxygen is absorbed by the oxygen absorbing action of the inner storage bag body 4 that holds the low oxygen concentration state and the protective bag body 3 that stores the granular food 1 is hermetically sealed, in an environment where this low oxygen concentration state is maintained. Therefore, the possibility that oxygen permeates into the inner storage bag 4 in which the protective bag 3 storing the granular food 1 is hermetically stored is reduced as much as possible. Keeps good storage environment (nearly oxygen-free) without increasing oxygen concentration That.

  In addition, since the present invention is provided with an adhesion preventing sheet material 7 that prevents the inner storage bag body 4 and the outer storage bag body 6 from being adhered between the inner storage bag body 4 and the outer storage bag body 6. The oxygen absorbing action of the second oxygen scavenger 5 arranged in the space between the inner storage bag body 4 and the outer storage bag body 6 is satisfactorily performed, and the oxygen that permeates and penetrates the outer storage bag body 6 is surely inside. Absorption can be performed without penetrating into the storage bag body 4, and therefore, a favorable low oxygen state (substantially oxygen-free) environment in the inner storage bag body 4 can be maintained for a long period of time.

  That is, when the adhesion preventing sheet material 7 is not provided, residual oxygen existing between the inner storage bag body 4 and the outer storage bag body 6 by the inner storage bag body 4 and the outer storage bag body 6 being in close contact with each other. Or the oxygen flow path of the oxygen entering from the outside is blocked, the oxygen absorbing action of the second oxygen scavenger 5 is hindered, and oxygen remaining between the inner storage bag body 4 and the outer storage bag body 6 from the outside Oxygen that has permeated through may permeate into the inner storage bag body 4 and the oxygen concentration in the inner storage bag body 4 may increase. However, as in the present invention, the inner storage is achieved by providing the adhesion prevention sheet material 7. The bag body 4 and the outer storage bag body 6 are not in close contact with each other, so that an oxygen flow path is secured, and the oxygen absorbing action of the second oxygen scavenger 5 works well. Absorbs oxygen existing in the space between the bag body 6 and the inner storage bag body 4 and the outer storage bag body. The space between the can to hypoxia.

  As described above, the present invention provides the residual oxygen in the inner storage bag body 4 outside the inner storage bag body 4 in which the granular food 1 is hermetically stored, that is, between the inner storage bag body 4 and the outer storage bag body 6. Since almost no oxygen penetrates and penetrates, the low oxygen state (substantially oxygen-free state) in the inner storage bag body 4 can be maintained for a long period of time, in other words, it is not easily oxidized for a long period of time. Thus, the oxidation of the granular food 1 during transportation and storage is suppressed as much as possible, and the granular food 1 maintains a good flavor and freshness immediately after processing and can be eaten deliciously. It becomes a periodical bagging granular food.

  Further, according to the present invention, the granular food 1 is first stored in a protective bag body 3 having puncture resistance, and the protective bag body 3 storing the granular food 1 is further converted into an inner storage bag body 4 having gas barrier properties. Since the hermetic container 1 stores a sharp food such as peanuts or almonds as the granular food 1, the protective bag 3 prevents piercing into the inner storage bag 4 of the sharp portion of the granular food 1; The problem that pinholes are generated in the inner storage bag body 4 can be reduced as much as possible. As a result, there is no problem that oxygen rapidly penetrates from the outside through the pinholes and oxidation does not proceed rapidly. A good hypoxic state (substantially oxygen-free state) in the bag body 4 is maintained.

  Specific embodiments of the present invention will be described with reference to the drawings.
