Description of the Related Art Background of the Invention Milk products prepared from reconstituted milk prepared by dissolving powdered milk such as skim milk powder or whole milk powder in water are not found in milk products prepared from fresh milk. Odors such as odors and heating odors may develop, and the commercial value may be reduced. Therefore, reduction or elimination of odor is desired.

解決する技術としては未だ確立していない。In the past, attempts have been made to deodorize or mask reconstituted milk in order to remove odors from reconstituted milk. Examples of methods for deodorizing odors include a method of heating the reconstituted milk and then vacuum deaeration, and a method of dissolving the skim milk powder and the like and aging for a certain period of time. However, none of these methods has been established as a technique for solving the problems such as a low odor removing effect and the odor reappearing during storage of products.

It has been proposed to add a flavor improver for dairy products prepared from skimmed milk powder, etc. (JP-A-55-124471), but until the odor is eliminated and the flavor of reconstituted dairy products is improved. It has not been put to practical use yet.

使用が難しい等の問題がある。Further, as a conventional deodorizing method,
There is a method of using activated carbon. When deodorizing is performed with activated carbon, fine powder is mixed in the deodorizing treatment liquid and cannot be used as it is for food and drink. If it is used for food and drink, operations such as filtration will be required. Further, in order to economically use an adsorbent such as activated carbon or a synthetic adsorbent, it is necessary to perform a deodorizing operation on the adsorbent to desorb the adsorbed substance and regenerate the adsorbent. However, the regeneration of the activated carbon has a problem that the adsorbed substance is hard to be desorbed and is not regenerated by a simple operation of passing hot water or caustic soda aqueous solution and is difficult to reuse.

In addition, non-functional group-type adsorbent resins include Duolite S-861, Duolite S-876, Amberlite XAD-4, Diaion SP800, Diaion HP20, Dowex S-112 and the like. As a method of contacting these resins with the reconstituted milk, a method of filling the column with the resin and passing the reconstituted milk or a tank in which the reconstituted milk and the resin are stirred and brought into contact with each other, and after deodorization, the resin is separated. There are ways to do it. Synthetic adsorption resin has high adsorption capacity and also excellent desorption property, so it can be easily regenerated with hot water or flexible soda.
Moreover, it has high physical strength and can be used repeatedly. Therefore, the odor of reconstituted milk can be removed efficiently and industrially,
A tasty restructured milk can be produced. Among these synthetic adsorption resins, the weakly basic anion exchange resin having an exchange group and the amphoteric ion exchange resin are regenerated with hot water or caustic soda, and then 6.0-7.2 with a mineral acid or the like as required.

ができる。When the reconstituted milk and the resin are brought into contact with each other, the concentration of the reconstituted milk is usually about 6 to 50%, more preferably 8%.
~ 25% is good. The reason why such a range is preferable is 6
This is because if it is less than 50%, the production efficiency is reduced with respect to the proportion of the resin used, while if it is more than 50%, the efficiency at the time of washing the resin is reduced. The temperature of the reconstituted milk is 25 to 50 ° C.
It is better to contact it with resin. Further, the liquid passing rate when the resin is packed in the column and brought into contact with each other is preferably in the range of SV = 2 to 10, and when the tank is a stirring type, the type of resin, the amount of resin or the type of reconstituted milk, the amount of milk Although it varies depending on the conditions, a deodorizing effect can be sufficiently obtained by contacting for about 30 minutes to 2 hours.

It is possible to efficiently remove, and it is possible to produce reconstituted milk having a good taste and no odor. The reconstituted milk thus obtained can be used as a raw material for drinkable milk, dairy products or other processed foods, and is extremely useful in practice.

0 liter was passed through the column at a temperature of 30 ° C. and a supply rate of 5 liter / h to obtain 8 liter of deodorized reconstituted skim milk. With respect to the reconstituted skim milk that had been subjected to this deodorizing treatment, the deodorizing effect was confirmed by a sensory evaluation by a panel of 8 persons. Untreated reconstituted skim milk was used as a control. As a result of the sensory evaluation, all the panels judged that the treated skim milk had no odor as compared with the control product. The pH of the treatment liquid treated with the non-functional adsorption resin such as S-861 and S-876 hardly changes from the pH before the treatment.

The column was filled with 1 liter of 5.00 L (manufactured by DOW), regenerated with an aqueous 1N NaOH solution, washed with 4 liters of water, and the column effluent was further washed with 1N HCl.
The column was neutralized until it reached H6.50 to give an odor removal column. The processing liquid was 5 after dissolving skim milk powder in a concentration of 9 w / w%.
Reconstituted skim milk refrigerated overnight at 0 ° C was used. 10 liters of this reconstituted skim milk was heated at a temperature of 30 ° C. and a flow rate of 5 liters / h.
Was passed through the column to obtain 6 liters of reconstituted skim milk that had been deodorized. The reconstituted skim milk subjected to this deodorizing treatment had no odor and had a good flavor. In order to investigate the changes in the components due to the deodorizing treatment, the components of the reconstituted skim milk before and after the treatment were analyzed. The analysis results are shown in Table 1. As shown in Table 1, the odor was removed from the treated reconstituted milk without any change in the component composition due to the treatment.

The column was filled with 1 liter of 5.00 L (manufactured by DOW), regenerated with an aqueous 1N NaOH solution, washed with 4 liters of water, and the column effluent was further washed with 1N HCl.
The column was neutralized until it reached H6.50 to give an odor removal column. As the treatment liquid, skim milk powder 8.95 w / w% and butter oil 3.51 w / w% were dissolved in hot water at 60 ° C, homogenized and cooled, and then reconstituted milk refrigerated at 5 ° C overnight was used. did. 10 liters of this reconstituted milk at a temperature of 30 ° C and a flow rate of 5
6 liters of reconstituted milk deodorized was passed through the column at a rate of 1 liter / h. The reconstituted milk that had been subjected to this deodorizing treatment had no odor and had a good flavor.

As a method of contacting these resins with the reconstituted milk, a method of filling the column with the resin and passing the reconstituted milk or a tank in which the reconstituted milk and the resin are stirred and brought into contact with each other, and the resin is separated after deodorization There are ways to do it.
The synthetic adsorption resin has a high adsorption capacity and also excellent desorption property, and can be easily regenerated by hot water or soft soda, and has high physical strength and can be repeatedly used. Therefore, the odor of the reconstituted milk can be efficiently and industrially advantageously removed, and the reconstituted milk having a good flavor can be produced. Among these synthetic adsorption resins, the weakly basic anion exchange resin having an exchange group and the amphoteric ion exchange resin are regenerated with hot water or caustic soda, and then adjusted to 6.0 to 7.2 with a mineral acid or the like as necessary.

~ 25% is good. The reason why such a range is preferable is 6
This is because if it is less than 50%, the production efficiency is reduced with respect to the proportion of the resin used, while if it is more than 50%, the efficiency at the time of washing the resin is reduced. The temperature of the reconstituted milk is 25 to 50 ° C.
It is better to contact it with resin. Further, the liquid passing rate when the resin is packed in the column and brought into contact with each other is preferably in the range of SV = 2 to 10, and when the tank is a stirring type, the type of resin, the amount of resin or the type of reconstituted milk, the amount of milk Although it varies depending on the conditions, a deodorizing effect can be sufficiently obtained by contacting for about 30 minutes to 2 hours. The reconstituted milk deodorized in this way can be made into powdered milk again by concentrating and drying.
