JP 2007-82413 A

  However, in view of the widespread preference required for smoked foods in recent years, the appearance of smoked lumber that can enjoy an unprecedented flavor and texture and foods using the smoked lumber is desired.

  Accordingly, an object of the present invention is to provide smoked lumber for foods that can meet various needs.

The first invention is a method for producing smoked lumber for food,
A first step of mixing peat and crushed wood pieces to obtain a mixture;
A second step in which the mixture obtained in the first step is inserted into a mold to obtain a dehydrated product that has been pressure-dehydrated;
And a third step of drying the dehydrated product obtained in the second step.

The second invention is a food processing method for adding flavor and texture with smoked lumber,
To give the smoked material by the manufacturing method of the smoked material of the first invention, characterized by smoking treatment the foodstuff by the smoked material.

  According to the present invention, as smoked lumber, for example, in addition to being able to add to the food the flavor and texture of wood pieces obtained by pulverizing trees such as cherry blossoms and walnuts, the wood pieces that peat has by mixing peat Unusual unique flavor and texture can be added to food.

  As a result, it is possible to provide a non-conventional flavor and texture that is required for smoked foods in recent years, and to provide smoked lumber for foods that can meet various needs. .

The flowchart which shows the manufacturing method of the smoked lumber of this embodiment. Explanatory drawing which shows the processing content of the pressure dehydration process of FIG.

  The smoked lumber for food of this embodiment contains components other than water derived from peat (peat) and crushed wood pieces, and is produced by the production method shown in FIG.

  Peat mined from a peat layer that has been killed by reeds, such as reeds, sedges and cattails, and accumulated under insufficiently decomposed conditions under low temperature and high humidity, has a high water content. Transported.

  First, the moisture content of the primary dehydrated peat is adjusted (FIG. 1 / STEP 10).

  In this embodiment, the moisture content of peat is adjusted to 300% to 400%. By increasing the water content to some extent, the fibers contained in the peat can be intertwined with each other during mixing, as will be described later.

  Next, the peat whose water content has been adjusted is mixed with crushed wood pieces (FIG. 1 / STEP 11, corresponding to the first step of the present invention).

  Specifically, peat with adjusted water content and crushed wood pieces are placed in a stirrer so that the dry weight ratio is a predetermined ratio, and stirred and mixed for a predetermined time according to the input amount. .

  Here, the crushed wood pieces are, for example, wood chips that are usually used for smoked lumber such as cherry blossoms, walnuts, persimmons, persimmons, apples, and beech (oak), and one or more of these may be used. .

  Moreover, the mixing ratio of peat with adjusted water content and crushed wood pieces is arbitrarily determined from the texture and flavor of the required smoked food, as will be described later.

  Next, the mixture of the mixed peat and the crushed wood pieces is subjected to pressure dehydration (FIG. 1 / STEP 12, corresponding to the second step of the present invention).

  In the pressure dehydration treatment, as shown in FIG. 2, a cylindrical mold 1, disk-shaped draining members 2 and 2 having a diameter corresponding to the inner diameter (inner diameter 60 mm) of the mold 1, and not shown A press device is used. The drainage members 2 and 2 are provided with a plurality of through holes 21 in the vertical direction, and moisture can flow out through the through holes 21.

  Specifically, in the pressure dehydration process, the mixture M is put into the mold 1 in a state where the upper and lower sides are sandwiched between the draining members 2 and 2 with respect to the cylindrical mold 1 placed on the upper side, An external force F (for example, 2 tons) is applied downward for a predetermined time (for example, 30 to 60 minutes) to the water draining member 2 using a press device.

  Thereby, the water | moisture content in the mixture M flows out from the through-hole 21 of the upper and lower water draining members 2 and 2, and the mixture M obtains tablet-like dehydrated material. This dehydrated product has a diameter of 60 mm and a thickness of about 7 to 13 mm.

  Next, the obtained dehydrated product is dried (FIG. 1 / STEP 13, corresponding to the third step of the present invention).

  Specifically, in the drying treatment, the dehydrated product obtained in STEP 12 is dried under a predetermined condition using a constant temperature dryer to obtain a peat mixed smoked lumber. As drying conditions at this time, for example, it is 2 days at 30 ° C. to 40 ° C. or 1 day at about 90 ° C., and the obtained peat mixed smoked lumber has a mass of 10 to 10 depending on its thickness. It is about 14g.

  Since this peat mixed smoked material is solidified in a state where the peat fibers are entangled by drying, it is possible to obtain a solid solid without requiring a separate treatment for molding.

  The above is the details of the method for producing smoked lumber for food, and the peat mixed smoked lumber produced in this way has a long combustion time of about 3 to 4 hours per piece (10 to 14 g). It corresponds to about 200 g of smoked wood made of only crushed wood pieces. That is, the peat mixed smoked lumber can burn for a long time with a small volume. Thereby, while being able to perform various smoke processing which changed conditions, such as smoke time and smoke density, with small smoked lumber, foodstuffs can be replaced and smoke continuous processing can be realized.

  Furthermore, as shown in Table 1, the processed food that has been smoked with the peat-mixed smoked material thus produced has the following characteristics.

  First, according to the experimental results when the cheese was smoked as a food, the mixing ratio of peat with adjusted water content and crushed wood pieces was such that their dry weight ratio was 1: 9 (peat 10%: wood pieces 90%) to 1: 1 (Peat 50%: Wood pieces 50%), the soot coloring becomes lighter. That is, by increasing the ratio of peat, coloring of the smoked processed food can be reduced.

  On the other hand, according to a questionnaire survey of 15 examiners when cheese is smoked as food, the mixing ratio of peat with adjusted water content and crushed wood pieces is 1: 9 (peat From 10%: 90% of wood pieces to 1: 1 (peat 50%: wood pieces 50%), it was found that peat flavor was added and bitterness appeared. That is, by increasing the ratio of peat, the addition of peat flavor and moderate bitterness can be imparted to the processed food.

  When the mixing ratio of peat with adjusted water content and crushed wood pieces was 3: 2 (60% peat: 40% wood pieces), the bitterness was strong and the taste was not good. Was pointed out by the show. Furthermore, smoked lumber made only of peat has a strong bitterness and puffiness and is not suitable as a processed food. On the other hand, when the mixing ratio of peat with adjusted water content and crushed wood pieces is 1: 9 (peet 10%: wood pieces 90%), it is pointed out that the smoke of the wood pieces is slightly strong and tastes a little. there were.

Therefore, according to the knowledge of the present inventor, the mixing ratio of peat with adjusted water content and crushed wood pieces is 1: 1 (peat 20%: wood pieces 80%) to 1: 1 (the dry weight ratio). A range of 50% peat: 50% wood is considered suitable.
Thereby, there can be provided processed foods with little soot coloring and making use of peat flavor and texture.

  Furthermore, the present inventor conducted a component analysis of (1) smoke from peat mixed smoked lumber and (2) smoke from only crushed cherry wood pieces. It has been found that the following characteristic components are contained in the smoke of mixed smoked lumber.

  Component analysis consists of (1) smoke of peat mixed smoked lumber, (2) smoke smoke from only crushed cherry blossom pieces, and a mass spectrometric test with a gas chromatograph eluting with diethyl ether as a solvent. went.

  As a result, methylphenol, methylhexanol, galactofuranose, and butylundecanyl phthalate were detected. These are substances that are not derived from cherry blossoms, and are presumed to add peat-specific flavor and texture to food. The

  As described above in detail, according to the peat-mixed koji lumber of this embodiment, in addition to being able to add flavor and texture due to pieces of wood obtained by crushing trees such as cherry blossoms and walnuts, the peat is mixed By doing so, a unique flavor and texture not found in the wood pieces of peat can be added to the food in a superimposed manner.

  As a result, it is possible to provide a non-conventional flavor and texture that is required for smoked foods in recent years, and to provide smoked lumber for foods that can meet various needs. .

  In addition, it is possible to provide a food with the texture and flavor of peat added by using peat, which has been focused only as a fuel, as a material other than fuel.
