Description

A method for removing scent of goat's milk and cow's milk, and its device

The present invention relates to a odor removal method of goat milk and milk, and a device thereof, in which an inherent goat odor and milk odor are strongly formed during storage of crude oil, by adsorbing and removing odor by passing activated carbon prior to sterilization in a goat milk and milk manufacturing process. At the same time, the salt is reduced to provide a good goat's milk and milk to drink for the patient.

Goat milk and milk are very beneficial foods to prevent disease by promoting the growth and development of children and providing the nutritional ingredients for adults. However, although the functionality of these foods has been fully acknowledged, especially goat goats avoid drinking due to the peculiar smell. This unique odor is caused by livestock breeding in the ranch, and stored at low temperatures for 2 to 3 days due to the mixing of abnormal odor by outside air when storing milk milked or storing it at the factory after crude oil collection. Pseudomonas spp. , A low-temperature microorganism, degrades lower fatty acids with 6 to 10 carbon atoms in milk fat, resulting in strong goat and milk odors.

Conventionally, there has been a method of adding a deodorizing process on the manufacturing process to remove the peculiar smell of goat milk and milk, but this method mainly blows the smell by directly contacting saturated steam between sterilization processes and vacuum (40 ~ 50cmHg) by sucking to remove the odor completely does not have the disadvantage, due to instantaneous heat contact there was a problem that the protein and vitamins are destroyed.

In addition, there is a method of removing milk odor and replenishing minerals by putting the milk in a container containing elvan, and heating it at low temperature (Korea Patent Publication No. 1998-022339). As a result, the desired deodorization effect could not be achieved. Especially, in the case of goat milk, the effect could not be expected.

In addition, sodium (Na), a component of goat's milk and milk itself, is an essential nutrient for human body's physiological activities, but the amount is limited because it may adversely affect patients with high blood pressure and kidney disease. At this time, goat's milk and milk are currently used in a patient diet without sodium filtration.

The activated carbon known to have excellent adsorptive power is applied to the treatment of goat milk and milk to remove odors in a simple manner so that anyone can easily drink by eliminating inherent odors.

It is an object of the present invention to provide a goat milk and milk that anyone can drink without objection by removing the peculiar smell of goat milk and milk using activated carbon.

It is also an object of the present invention to provide a goat milk and milk which is good for drinking in a patient manner by reducing salts at the same time as removing odors.

In addition, an object of the present invention is to provide a method and an apparatus which can be used at home by eliminating the complexity of the process by removing the odor in a separate process from the sterilization treatment in removing the odor.

Figure 1 illustrates an apparatus that can be used to practice the removal method according to the present invention.

Hereinafter, a method of removing the odor of goat milk and milk of the present invention will be described in detail for each step.

<Preheating process>

Preheat the crude oil (goat milk and milk) collected on the farm or crude oil with strong intrinsic odor during storage to 40-50 ℃.

<Adsorption process>

The preheated crude oil is passed through activated carbon to adsorb and remove inherent odors and salts. Activated carbon is preferably one obtained from palm and arc angles and allows crude oil to pass through a layer of activated carbon of a constant particle size. In this case, the smaller the particle size, the larger the surface area of activated carbon, so the deodorizing effect is increased. However, if the particle size is too fine, activated carbon may be mixed in the treated oil.In order to prevent this, it is necessary to filter by using a precise filter. Not preferred. In general, the use of activated carbon of 50 to 100 mesh size is preferred for the deodorizing effect and the efficiency of the process.

<Filtration process>

The adsorbed treated oil which has passed through the activated carbon is filtered through a filter so that the activated carbon is not mixed with the finished goat and milk. As the filter, any conventional filter capable of filtering the activated carbon particles used for adsorption may be used. In the case of using activated carbon of 50 to 100 mesh size, a fibrous filter of preferably 0.1 μm may be used.

<Centrifugal separation process>

The treated oil after the filtration process is once again centrifuged and purified.

In some cases, it can be replaced by leaving it for a certain time instead of centrifugal separation, and if the filtration efficiency is good, this step may be omitted. In particular, when carried out at home can be drinking as it is without going through a separate centrifugation process after filtration.

Crude oil, which has undergone the odor removal process as described above, is a low-temperature long-time sterilization method (LTLT) (60-65 ℃, 25-30 minutes), a high-temperature short-time sterilization method (HTST) (72-73 ℃, 15 to 20 seconds) and ultra-high sterilization (UHT) (120 to 125 ° C, 2 to 3 seconds), etc., through conventional sterilization treatment processes. In addition, goat milk or milk already produced through the sterilization process may be removed after the intrinsic odor through the odor removal process, and in particular, in the concentrated value for raising sheep or cows by removing the odor of crude oil directly at home by the above method You can drink it.

Goat milk and milk produced through the deodorization process as described above is suitable for the patient type that should be limited salt in particular to reduce the salt (Na) by about 40%.

In addition, by using the deodorized goat milk or milk in the manufacturing process of soy milk, liquid and semi-solid livestock products, it is possible to produce more flavored and non-reflective dairy products, such as fermented milk, cheese, butter, milk liquor, etc. .

In addition, the odor removal method according to the present invention can also be used to remove the fermentation odor produced by abnormal fermentation in the production of Yuju (乳酒).

Hereinafter, on the basis of the accompanying drawings will be described an apparatus used in the deodorizing process of the present invention described above.

1 is an example of a device capable of practicing the present invention, in particular an apparatus suitable for home use, which is one of the preferred embodiments of the present invention. First, the crude oil 501 introduced through the inlet 11 of the barrel 1 passes through the activated carbon 3 filled in the filtering network 2 inside the barrel, and the unique oils and salts are adsorbed and removed. At this time, the material of the keg 1 and the filtering net 2 is not particularly limited, but preferably a stainless material is used. The mesh size of the filter net 2 is to be smaller than the activated carbon filled therein, and preferably, when the activated carbon of 50 to 100 mesh is filled, the filter net 2 has a pore size of about 300 mesh. Activated carbon filled therein can adjust the particle size in consideration of the filtration time, etc., but the particle size of about 50 to 100 mesh is suitable for use in a general apparatus. The adsorption treatment oil 502 flowing out of the filter net 2 through the activated carbon 3 is filtered and discharged to the outside through the fibrous filter 4 provided in the lower part of the barrel 1. At this time, the fibrous filter should have a filtering power enough to filter out the activated carbon (3) mixed in the adsorption oil, and when using a activated carbon of 50 to 100 mesh size, preferably a 0.1 μm fibrous filter. The treated oil 503 filtered and discharged as described above is commercialized by sterilization through the centrifugal separation process described above.
