JPS6170953A - Extraction of marrow component of animal bone - Google Patents

Abstract

PURPOSE:To promote the dissolution of the active component of the marrow, e.g. soluble phospholipid, etc., and to suppress the increase of peroxide value, by adjusting the pH of the paste of finely crushed animalbone to a specific level with a small amount of ascorbic acid, and heating the mixture. CONSTITUTION:Paste prepared by finely pulverizing the bone of an animal such as cattle, pig, poultry, etc. is added with 0.1-2wt% ascorbic acid to attain 3-6pH. The product is heated preferably at 60 deg.C for 30min-1hr to effect the dissolution of the marrow component.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for extracting bone marrow bones, which are effective for improving health, from animal bones such as cows, pigs, and birds.

[Conventional technology]

Conventionally, the bone marrow of animal bones contains various nutrients, especially soluble phospholipids and soluble phospholipids, which are said to be nutrients for the brain. ～20136 Publication, Special Publication No. 1977-
This is known as shown in Japanese Patent No. 11583. Furthermore, as shown in Japanese Patent Publication No. 54-40623, it has been proposed to produce foods using animal bone components as raw materials.

,Then, the method of Japanese Patent Publication No. 43-20136 is as follows.
After coarsely crushing the animal bone, it is frozen, placed in a centrifuge, and heated while utilizing the difference in thawing temperature to extract the various components in the bone marrow. According to the method disclosed in Japanese Patent Publication No. 44-11583, animal bones are cooled to an extremely low temperature and crushed, and then the bone marrow components are leached out using warm water or dilute saline with a protein coagulation rate of 0.4 kg or less. In addition, the method of Japanese Patent Publication No. 54-40623 involves crushing animal bones, cutting them into pieces, and then grinding them into a paste of fine particles, but it does not extract soluble phospholipids. .

[Problem that the invention seeks to solve]

However, the above-mentioned conventional extraction method has problems in that soluble phospholipids and the like are not sufficiently eluted and the peroxide value tends to increase.

The object of the present invention is to solve the above-mentioned problems and to provide a method for extracting bone marrow components from animal bones, in which bone marrow components enriched with vitamin C can be obtained from animal bones.

[Means to solve the problem]

The method for extracting bone marrow components from animal bones according to this invention uses 0.1% to 2% ascorbic acid based on K, which is made from finely divided animal bones.
(weight ratio), the pH is adjusted to 3 to 6, and the bone marrow component is eluted by heating.

[Effect]

As mentioned above, this invention adds ascorbic acid to a paste made from finely ground animal bones to bring the pH to or near the isoelectric point, thereby reducing the amount of soluble phospholipids and proteins extracted compared to conventional ascorbic acid. In addition to increasing the peroxide value in the extract obtained by the reducing action of ascorbic acid, it also suppresses the increase in peroxide value due to changes over time, and further increases the The extract can be enriched with vitamin C via ascorbic acid.

In addition, in this invention, it is preferable that the paste made from finely ground animal bones has a mesh size of 100 to 200, and adding ascorbic acid to the paste in an amount of 0.1% to 2% means that outside this range the PH This is because if the pH does not fall within the range of 3 to 6 and the pH falls outside this range, the amount of bone marrow components such as soluble phospholipids extracted will decrease. When extracting bone marrow components, it is preferable to heat the bone marrow component at about ω°C for a period of about 1 hour.Furthermore, after extraction, the liquid part and the incompletely dehydrated solid part are separated using a centrifuge, and the liquid part is used for foodstuffs. It is used to improve health by adding it to

〔Example〕

Using beef bones frozen at -15°C to m°C, coarsely crush them to about 1crr1 using Masuko Sangyo Exhibition's beef bone paste line,
Next, after making it into minced pieces, add the same amount of ice, stir, and further crush 2 to 31 RLK, then 2
Grind twice to make a paste finer than 100 mesh.

This paste is prepared by rapidly freezing the paste or the paste with a moisture content of about -% IcL - ascorbic acid 0.8
? and 200 y of water were added to adjust the pH to about 4. This was heated to about 60°C while gradually stirring as a raw material, kept at this temperature for 1 hour, and the evaporated water was replenished during the process to reach a final temperature of 300°C, and the liquid contained soluble phospholipids, proteins, etc. elute bone marrow components. After that, the liquid part 1 was centrifuged at a rotation speed of 5000 r, r, m.
It was separated into 95CC and an incompletely dehydrated solid portion 1050C.

The bone marrow component was eluted according to the same reference example as the above example except that L-ascorbic acid was not added.
This was separated into a liquid part and a solid part.

When the good products, that is, the liquid portions obtained by the methods of the above Examples and Reference Examples were analyzed and compared, the results shown in Table 1 below were obtained.

Table 1 In Table 1 above, in the examples, L-ascorbic acid decomposed during heating and decreased from 0.4% at the time of addition to 25%.

In addition, after storing the good products obtained in the above examples and reference examples in a constant temperature bath at 10°C for several days, the peroxide value was measured.
In the example, the peroxide value was 1, whereas in the reference example, the peroxide value was 4.

From the above results, compared to the reference example, the sample obtained in the example has a higher elution amount of soluble phospholipid and protein, has a lower peroxide value, and also has a lower peroxide value due to changes over time. was suppressed and kept small.

In this invention, the animal bones are not limited to cows, but can be similarly applied to pigs and birds, and the method for obtaining the animal bone paste as a raw material can be any conventionally known appropriate method. .

〔Effect of the invention〕

As explained above, according to the present invention, the elution amount of active ingredients in bone marrow such as soluble phospholipids can be increased by the simple means of adding ascorbic acid to animal bone paste and adjusting the pH. In addition, it is possible to suppress the peroxide value and its increase due to changes over time, and it is also possible to add vitamin C, which is useful for nutritional enrichment.
