大量生産可能な脱水法に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a dehydration method that can be mass-produced and efficiently removes moisture from food by blocking air without changing the taste of the food through simple operations. Regarding.
食品中の水分は、食品の鮮度低下、冷凍破壊、解凍時の
ドリップの発生など、各種の品質低下の原因となってい
る。Moisture in food is a cause of various quality deterioration, such as loss of freshness of food, destruction of food by freezing, and occurrence of drips during thawing.

た。Generally, methods for removing moisture from food include drying the food by blowing low-humidity air through it, and dehydrating the food by bringing it into contact with high-osmotic substances such as salt or sucrose. In both cases, the texture and taste changed, and it was not possible to remove only water without changing the quality of the food.

た。After that, removing only the water content without changing the quality of the food will help preserve the freshness of the food, prevent freezing damage, improve shape retention, reduce heating energy and time during cooking, and reduce the generation of peroxides due to heating. Because of its advantages, methods of dehydrating foods at low temperatures through osmotic pressure differences have been used.
[It was. This method is used, for example, in Japanese Patent Publication No. 58-58124,
As described in () SP-/1383376, this is a dehydration method in which food is wrapped in a special sheet-like material that combines a high osmotic pressure substance and a semipermeable membrane. However, this method is unsuitable for automation using a machine, requires manpower, and is extremely inefficient.
本発明は上記の事情に鑑み、容易に機械化可能で人手を
要さず、人聞の食品を扱うのに適した食品の脱水法を提
供することを目的とする。In view of the above circumstances, an object of the present invention is to provide a food dehydration method that can be easily mechanized, does not require human labor, and is suitable for handling human food.

。Means for Solving Problem C] The present invention has been made to achieve the above object,
The gist is that food is packaged with a semi-permeable membrane, the food is brought into contact with a highly osmotic substance to dehydrate it, and at least a portion of the highly osmotic substance that has absorbed water and other substances is concentrated under reduced pressure at appropriate times.
A food dehydration method in which moisture and other absorbed impurities are removed and returned to their original state, and the moisture concentration in the above-mentioned high osmotic substance that comes into contact with food through a semipermeable membrane is maintained below a predetermined level. be.
以下、本発明の詳細な説明する。 The present invention will be explained in detail below.

れる食品等である。The foods that are compatible with the method of the present invention in J3 are raw seafood, raw salmon animal foods such as meat, and plant foods such as vegetables and fruits.
In particular, these include foods whose preservability is increased by dehydration, foods whose resistance to freezing is improved, foods whose taste is improved, and foods whose cooking properties are improved.
また、使用づる半透膜は、水および水分子とほぼ同じ大
ささの分子は通すが高分子物を通さず、食品に直接接触
してb安全な(>のが用いられる。In addition, the semipermeable membrane used is one that allows water and molecules approximately the same size as water to pass through, but does not allow polymers to pass through, making it safe for direct contact with food.
例えば低延伸性ビニロンフィルム、言過セロハン。For example, low stretch vinylon film and cellophane.

ルアミン、ホルムアルデヒド。Collodion membranes, ethylene vinyl acetate copolymer films, etc. are suitable. These films contain ammonia, trimedelamine, dimethylamine, and formaldehyde, which are unnecessary components in water and food.
食塩などは透過づるが、有効成分ぐある蛋白質。It is a protein that is easily penetrated by salt and other substances, but contains active ingredients.
糖類、ミネラル、ビタミン類などはほとんど透過しない

好適である。In addition, the high osmotic pressure substance must be one that does not substantially pass through the semipermeable membrane, but since it is not possible to completely prevent its permeation, it is classified as food 2 food additive 2 food processing material. Those that have been approved for use will be used. However, since the food to be dehydrated is solid, it is effective to use a liquid substance as the high osmotic pressure substance. For example, starch syrup, concentrated aqueous sucrose solution, propylene glycol (PG), glucose, isomerized viscosity, fructose, oligosaccharide, and the like are suitable.

物質7等を付着同伴した状態で取出される。Next, FIG. 1 shows an example of a process for carrying out the method of the present invention. First, food 1 is packaged using semipermeable membrane packaging machine 2.
Vacuum packaging is preferred because it improves the adhesion between the semipermeable membrane and the food and increases dehydration efficiency. Next, it is led to the contact tank 3 and immersed in the stored liquid zero osmotic pressure substance. After a predetermined period of time has elapsed, the dehydrated product 4 remains packaged in the semipermeable membrane, with the high osmotic substance and the water that has passed through the semipermeable membrane and transferred to the high osmotic substance on its outer surface. It is taken out with higher boiling point substances 7 etc. attached to it.

。On the other hand, the high osmotic pressure substance in the contact tank 3 is gradually diluted by the transfer of moisture and other substances that have passed through the semipermeable membrane from the food 1, but at least a part of it is constantly extracted and concentrated under reduced pressure.
water and other substances such as ammonia, trimethylamine, formaldehyde, etc. are removed. At this time, it is necessary to prevent the internal temperature from increasing more than necessary when the pressure is reduced, but the latent heat of vaporization of water allows the temperature to be maintained at a low temperature without using a cooler. The high osmolarity substance from which water and other substances have been removed is circulated to the contact tank 3,
Moisture and other contents in the 8 osmotic substances in the contact tank 3 are maintained below a predetermined level. In addition, the removed moisture and others are cooled,
It is easily collected by a collector 6 such as a filter, and treated by a general wastewater treatment device 7 such as activated sludge treatment.

J:い。Note that among the substances other than water that transfer to high osmotic pressure substances from the food, ammonia, trimethylamine, dimethylamine, and formaldehyde have a boiling point lower than that of water and cause a bad odor, causing a problem even at 1 pI) ffl. However, it is necessary to quickly remove the substances that cause these malodorous substances from the high osmotic pressure substances, and they can be easily removed by reducing the pressure. In addition, amino acids, peptides,
Phosphorous Pa salts, sulfate salts, and other salts do not have much of an adverse effect even if they accumulate in high osmotic substances, and because their boiling points are higher than water, most of them adhere to the semipermeable membrane that packages food and are removed from the system. Go out. Therefore, there is an equilibrium between the amount of water that permeates through the semipermeable membrane and the amount of water that adheres and leaves the system, but the concentration is between 0.5 and 1. □wt
% and usually does not become more concentrated and will not have an adverse effect on food. However, high osmotic pressure substances can be managed using the amount of filtrate they contain as an indicator.

る方法である。As described above, the present invention packages food in a semi-permeable membrane, and then wraps the food in a semipermeable membrane. 3. Take out the osmotic substance and bring it into contact for a predetermined period of time,
In addition, at least a portion of the hyperosmotic substance that has come into contact with the food and absorbed moisture and other substances is concentrated under reduced pressure and returned to its original state, so the water content in the hyperosmotic substance that dehydrates the food is otherwise constant. Since the dehydration power is constant, a product with a constant dehydration rate can be obtained. Furthermore, each of the above steps is a method that has many advantages such as being easily automated and suitable for mass production.
