引き起こすという欠点がある。Other methods of dehydration include wrapping food in cellophane and placing it in a water-absorbing substance such as sand, natural zeolite, or silica gel. However, since dehydration methods using water-absorbing substances are carried out at room temperature or at elevated temperatures to shorten the drying time, quality may deteriorate due to autolysis, denaturation of proteins, decomposition of flavor components by enzymes, etc. It has the disadvantage of causing

う欠点かある。Furthermore, as a dehydration method by contact with water-absorbing substances,
Dehydration methods include soaking in highly osmotic substances such as salt, sugar, and miso. However, this method also causes autolysis, denaturation of proteins, and decomposition of flavor components due to arroxin. Another disadvantage is that the taste of foods with high osmotic pressure may change.

(実施例)
以下、図面を参照して本発明の丈施例について説明する
。(Example) Hereinafter, length examples of the present invention will be described with reference to the drawings.
第1図および第2図は本発明による食品の脱水方法の一
実施例を示す図である。FIGS. 1 and 2 are diagrams showing an embodiment of the food dehydration method according to the present invention.
第1図において、まず例えば魚等の食,見12を準備し
、この食品]2を半透膜]4て包装する。In FIG. 1, first, a food such as fish is prepared 12, and the food is packaged using a semi-permeable membrane 4.
続いて、このように包装された食品]2を、pめ密閉容

ことができるか、特に七ロ/\ン、ビニロンフィルムか
望ましい。In this example, the semipermeable membrane 4 is not particularly limited as long as it is a water-permeable material, and may be made of a material such as silica film, vinylon film, film with micropores, nonwoven fabric, etc. In particular, vinylon film is preferable.

使用できるが、吸水性を有する物質であれば特に限定さ
れない。また、吸水性物質16として食塩、砂糖、味噌
等の高浸透圧食品を用いることもできる。In addition, the water-absorbing substance 16 includes starch/acrylate graft polymer, carboxymethyl cellulose crosslinked product, vinyl alcohol/acrylate copolymer, polyacrylonitrile hydrolyzate, crosslinked polyacrylate, modified polyvinyl alcohol, Acrylate polymer, acrylate/acrylamide copolymer, isobutylene/maleic anhydride copolymer, alginate, starch, mannan, agar, gum tracanth, gum arabic, dextrin, glue, gelatin, collagen, casein, sand, Natural zeolite, diatomaceous earth, ash, silica gel, inorganic salts, etc. can be used, but there are no particular limitations as long as the material has water absorption properties. Furthermore, high osmotic pressure foods such as salt, sugar, and miso can also be used as the water-absorbing substance 16.
続いて、密閉容器]0を氷温下で減圧状態に12、例え
ば1時間保持して食品]2の脱水を行なう。Subsequently, the airtight container [0] is held in a reduced pressure state at ice temperature 12, for example, for 1 hour to dehydrate the food [2].
減圧状態の程度としては、例えば]. O O mnl
lIg程度が考えられる。Examples of the degree of reduced pressure include]. O O mnl
Possibly about lIg.
ここで、氷温とは0°Cから食品の氷結点までの温度帯
をいう。第2図に示すように、食品を徐々に冷凍してい
くと、食品は破線に示すような混度変化をおこす。Here, freezing temperature refers to the temperature range from 0°C to the freezing point of food. As shown in Figure 2, when food is gradually frozen, the mixture of the food changes as shown by the broken line.
すなわち、食品を冷凍すると、破線に示すように、まず
急速に温度低下が生じ、次に胤度かわずかに上昇し氷結
点で温度が維持され、その後再び温度が低下する。That is, when food is frozen, as shown by the broken line, the temperature first decreases rapidly, then the tenderness increases slightly, the temperature is maintained at the freezing point, and then the temperature decreases again.
本実施例においては、上述のようにO℃と氷結点の間の
氷温状態を約1時間保トエする(第2図実線)。In this example, as described above, the freezing temperature state between 0°C and the freezing point is maintained for about 1 hour (solid line in Figure 2).
このように、半透膜14て包装された食品]2を吸水性
物質16中に所定時間保持することにより、食品]2中
の水分が半透膜]4を通過して吸水性物質16内に吸水
され、このようにして食品12の脱水が行なわれる。In this way, by holding the food [2] packaged with the semipermeable membrane [14] in the water-absorbing material 16 for a predetermined period of time, the moisture in the food [2] passes through the semi-permeable membrane [4] and enters the water-absorbing material 16. In this way, the food 12 is dehydrated.
本実施例によれば次のような効果か発揮される。According to this embodiment, the following effects are achieved.
■氷温下で処理を行うため、食品12を0℃以下に維持
することができ、自己消化、蛋白の変成、酵素による旨
み戊分の分解等の化学的変化による品質の低下が防止で
きる。また食品]2を氷桔点以上に維持することができ
るので、食品は凍結されず、凍結による細胞組織の破壊
を防1ヒすることができる。(2) Since the processing is carried out at freezing temperatures, the food 12 can be maintained at 0° C. or below, and deterioration in quality due to chemical changes such as autolysis, protein denaturation, and decomposition of flavor components by enzymes can be prevented. Furthermore, since the food [2] can be maintained above the freezing point, the food is not frozen, and destruction of cell tissue due to freezing can be prevented.
■食品12を半透膜14て包装しているため、食品12
中の旨み成分は食品12中に残留するので、食品本来の
味を損なうことなく効果的に水のみを食品から除去でき
る。■Since the food 12 is packaged with a semipermeable membrane 14, the food 12
Since the flavor components inside remain in the food 12, only water can be effectively removed from the food without impairing the original taste of the food.
■減圧下で処理するため、処理時間が短い。すなわち、
脱水速度は半透膜14を境として、内側(食品12側)
と外側(吸水物質16側)の浸透圧の差に依存するが、
減圧下で処理することにより、食品12側から吸水物質
16側への水分の移行速度が速くなるため、短時間で処
理が可能となる。■Processing time is short because it is processed under reduced pressure. That is,
The dehydration rate is determined from the inside (food 12 side) with the semipermeable membrane 14 as the boundary.
It depends on the difference in osmotic pressure between and the outside (water absorbing material 16 side),
By processing under reduced pressure, the speed of moisture transfer from the food 12 side to the water-absorbing substance 16 side becomes faster, so that the processing can be carried out in a short time.
なお、上記実施例において、密閉容器10内の圧力を1
0 0 ++++nHgとした例を示したが、処理江
力は、品質、処理時間およびコスト等を考慮して任意に
定めることができ、大気圧以下であれば特に限定されな
い。In addition, in the above embodiment, the pressure inside the closed container 10 is set to 1
Although an example of 0 0 ++++nHg has been shown, the processing power can be arbitrarily determined in consideration of quality, processing time, cost, etc., and is not particularly limited as long as it is below atmospheric pressure.
次に本発明の具体例について説明する。Next, specific examples of the present invention will be explained.

の脱水を行なった。(Specific example) 1.50g of raw salmon fillet as food (initial moisture content: 75%)
) and place it on cellophane (300mm x 300mm)
It was packaged in Next, this raw salmon was covered with a super absorbent resin (AQUA KEEP IOSHP manufactured by Steel Chemical Co., Ltd.) used as a water-absorbing substance, and placed in a vacuum desiccator, which is a closed container. Next, the inside of the vacuum desiccator is heated for about 1 hour using a vacuum pump.
The pressure was reduced to 0.00 mmllg, and the vacuum desiccator was placed in an ice-cold refrigerator at -1°C and maintained for 1 hour to dehydrate the raw salmon.
