Description

  The present invention relates to a novel beverage and a method for producing the same. By containing a specific milk component, the beverage of the present invention is useful for the prevention and treatment of various bone diseases such as osteoporosis, fractures, rheumatism and arthritis.

  In recent years, various bone-related diseases such as osteoporosis, fractures, and back pain are increasing with the aging of the world on a global scale, which is a serious social problem. This is considered to be caused by insufficient intake of calcium, a decrease in calcium absorption capacity, and postmenopausal hormone imbalance. In order to prevent various bone diseases such as osteoporosis, fractures, and back pain, bone formation by osteoblasts is promoted from a young age to increase the amount of bone in the body as much as possible, and maximum bone mass and bone strength (bone density) + Bone quality) is considered effective. Bone quality refers to bone microstructure, turnover, micro fracture, and calcification. In addition, as a method for preventing various bone diseases such as osteoporosis, fractures, and back pain, it is conceivable to suppress bone resorption by osteoclasts. Bone repetitively undergoes balanced resorption and formation (remodeling), but due to changes in hormone balance after menopause, etc., bone resorption exceeds bone formation, which is a variety of bone diseases such as osteoporosis, fractures, and back pain Cause. Therefore, it is possible to strengthen the bone as a result by suppressing bone resorption by osteoclasts and keeping the bone strength constant.

  Under these circumstances, for the purpose of strengthening bones, calcium salts such as calcium carbonate, calcium phosphate, and calcium lactate, and natural calcium preparations such as whey calcium, beef bone meal, eggshell, etc., alone for pharmaceuticals, foods and drinks, feeds, etc. What is added to is taken. Or these calcium agents are ingested together with substances having a calcium absorption promoting effect such as casein phosphopeptides and oligosaccharides in medicines, foods and drinks, feeds and the like. However, the absorption rate of calcium when ingesting these calcium salts and natural calcium preparations added to foods and drinks is 50% or less, and it is said that a lot of calcium is not absorbed and is discharged outside the body. Yes. In addition, even if calcium is absorbed by the body, the affinity to bone varies depending on its form and the type of other nutritional components that are taken at the same time, so it does not necessarily show an effect of improving bone metabolism or strengthening bone. There is also. In addition, female hormone preparations, active vitamin D3 preparations, vitamin K2 preparations, bisphosphonate preparations, calcitonin preparations, etc. are known as drugs for the treatment of osteoporosis and bone strengthening, and new drug development such as anti-RANKL antibodies has been developed. It is being advanced. However, these medicines may have side effects such as tinnitus, headache, and loss of appetite. Furthermore, these substances cannot be added to food and drink at present from the viewpoints of safety and cost. On the other hand, due to the nature of various bone diseases such as osteoporosis, fractures, and back pain, it can be taken orally for a long period of time, acting to promote bone formation and suppress bone resorption to increase bone strength and prevent or Development of food and drink that can be expected to have a therapeutic effect is desired.

  The beverage of the present invention can reinforce bone by ingesting 200 ml or more per kg of body weight in a test with experimental animals described later. The intake in this experimental animal corresponds to the intake per adult in the blood drug concentration (Mitsuyoshi Nakajima (1993) “Volume 8: Efficacy Evaluation”, Yodogawa Shoten, 2-18). Bone can be strengthened by ingesting 200 ml or more of the beverage of the present invention per person per day, and the effects of prevention and treatment of various bone diseases such as osteoporosis, fractures, rheumatism and arthritis can be particularly expected.

  Preparation Examples, Examples and Test Examples are shown below, and the present invention will be described in more detail. However, these are merely illustrative, and the present invention is not limited by these.

[Preparation Example 1]

The column was then thoroughly washed with deionized water and then eluted with a linear concentration gradient of 0.1-2.0 M sodium chloride. And the elution fraction containing angiogenin is fractionated by S-Sepharose cation exchange chromatography (manufactured by Amersham Biosciences), the obtained angiogenin-containing fraction is heated at 90 ° C. for 10 minutes, and centrifuged. The precipitate was removed by separation. Further, this angiogenin-containing fraction was treated with Superose 12 gel filtration chromatography. This eluate was desalted with a reverse osmosis membrane and then freeze-dried to obtain 16.5 g of an angiogenin fraction having angiogenin purity of 90%. These series of treatments were repeated 30 times.

After 10 μl of this solution was dried up, it was dissolved in 20 μl of 0.1 M ammonium bicarbonate containing 8 M urea and 1 mM tris (carboxyethyl) phosphine (TCEP) and heated at 56 ° C. for 30 minutes. After returning to room temperature, 5 μl of a 100 mM iodoacetamide solution was added and allowed to react for 30 minutes in the dark. 54 μl of ultrapure water was added thereto, 10 μl of 0.1 μg / ml trypsin and 10 μl of 0.1 μg / ml lysyl endopeptidase were added, and the mixture was reacted at 37 ° C. for 16 hours. Thereafter, 3 μl of formic acid was added to stop the reaction to obtain a peptide solution for measurement sample. Each sample solution was diluted 6-fold with 10 fmol / μl of an internal standard peptide solution (containing 0.1% formic acid, 0.02% trifluoroacetic acid (TFA), 2% acetonitrile), and 2.5 μl of the diluted solution was diluted with LC. Analysis was performed with / MS / MS.

Peptide separation was gradient eluted using an HPLC system. Specifically, MAGIC C18 0.2 mm ID × 50 mm with a column 5 μl peptide trap was used, and the flow rate was 2 μl / min, using a MAGIC 2002 HPLC system. As the solvent for HPLC, A solution: 2% acetonitrile-0.05% formic acid and B solution: 90% acetonitrile-0.05% formic acid were used. As the elution conditions, the B solution was gradient eluted from 2% to 65% over 20 minutes.
The measurement target ion of cystatin is m / z 914.4 when the parent ion is NH2-QVSGMNYFLDVELGR-COOH, the MS / MS target ion is m / z 948.7 when NH2-FLDVELGR-COOH, and the measurement target ion of angiogenin is The parent ion was NH ₂ —YIHFLTQHYDAK-COOH and m / z was 768.8, and the MS / MS target ion was NH ₂ —FLTQHYDAK-COOH and m / z was 1122.8. The internal standard peptide has a parent ion of NH ₂ -ETTVFELPEK-COOH (wherein P carbon is labeled with C13 and nitrogen is labeled with N15) and m / z 656.9, and the target ion of MS / MS is NH ₂ − FENLPEK-COOH (wherein the carbon of P was labeled with C13 and the nitrogen was labeled with N15) was carried out at m / z 882.4.
LCQ Advantage was used for MS. From the obtained chromatogram, the peak area of each protein was determined, and the concentration was determined from the ratio to the internal standard peptide.
