JP2012036175A - Oral composition containing collagen peptide and vitamin c - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an oral composition containing collagen peptide and vitamin C, exhibiting controlled discoloration.SOLUTION: The discoloration of the oral composition containing collagen peptide and vitamin C is remarkably controlled by using sodium ascorbate or calcium ascorbate as ascorbic acid to be mixed with the collagen peptide, in comparison with the cases using free ascorbic acid or other ascorbates. The discoloration of the oral composition is also remarkably controlled by containing plant extracts such as extract of lotus.

Description

  The present invention relates to an oral composition comprising a collagen peptide and a sodium or calcium salt of ascorbic acid.

  Ascorbic acid (vitamin C) is a white crystalline water-soluble vitamin that cannot be produced in the human body. Known effects include scurvy prevention effects, immune function enhancing effects, anticancer effects, antioxidant effects, skin beautifying effects based on melanin suppression and collagen synthesis promotion.

Ascorbic acid can be taken from citrus fruits such as lemons, fruits such as strawberries and kiwi, supplements, and the like.
Collagen, on the other hand, is a major protein that constitutes animal tissues, and is an important component for increasing the elasticity and strength of bones, cartilage, tendons, skin, and the like. Various external compositions and compositions for internal use have been developed to compensate for collagen that decreases due to effects such as aging. Moreover, even if high molecular weight collagen is ingested as it is, the absorbability is low, and it is known that it is desirable to ingest it as a low molecular weight collagen peptide (Non-patent Document 1).

  However, ascorbic acid is known to change color due to the presence of moisture or to change color due to blending with other components, and is often discolored (Patent Document 1). Such discoloration makes it look bad and significantly reduces the commercial value. Therefore, in the preparation containing ascorbic acid, it is necessary to design and manufacture the preparation while paying attention to the stability of ascorbic acid.

Regarding stabilization of ascorbic acid, for example, Patent Document 2 discloses a method of adding a sugar alcohol or the like.
In addition, the problem of discoloration may be that tablet supplements maintain the beauty of appearance by coating the core tablet with a water-soluble polymer. However, if the discoloration of the core tablet is significant, the color may be perceptible to the naked eye through the coating. On the other hand, when the coating thickness is increased, the size of the tablet increases, making it difficult to take. In addition, it is difficult to apply a coating for the purpose of color masking in powder or granule supplements.

Specifically, it can be evaluated by the method shown in Example 1 below.

  EXAMPLES Hereinafter, although an Example is given and this invention is demonstrated in more detail, this invention is not limited to them.

In order to examine the color change due to the combination of collagen peptides having different average molecular weights and various vitamin C, a test was conducted in which each powdery material was mixed.
Various collagen peptides, various vitamin Cs, and cellulose were weighed according to the formulation shown in Table 1, placed in a plastic bag, and mixed about 30 times. Each mixed powder was divided into 2 g plastic petri dishes and stored in a constant temperature bath at 40 ° C. and 75% RH for 48 hours, and the appearance change of the powder was measured with a color difference meter (the color difference meter was SpectroColorMeter manufactured by Nippon Denshoku Industries Co., Ltd.). SE2000 is used). The difference between the starting sample and the sample stored at 40 ° C. and 75% RH was obtained by calculating ΔE (a * b *) by the Hunter equation.

The color was also confirmed with the naked eye. The color closest to the sample was recorded using a JIS color name book (JIS Z8102 compliant).
The blending and evaluation results are shown in Table 1 and Table 2.

  From the results shown in Tables 1 and 2, it was found that the sample containing free ascorbic acid and collagen peptide was significantly discolored. Further, the color change was more remarkable as the molecular weight of the collagen peptide was smaller.

  Compared with free ascorbic acid, discoloration is remarkably suppressed when ascorbic acid sodium or calcium salt is used, and other ascorbates (magnesium salts, iron salts) are used. It was also found that the discoloration was significantly suppressed compared to the case where it was.

  Further, it was found that the molecular weight of the collagen peptide is preferably 3000 or more from the viewpoint of the effect of suppressing discoloration.

  In the same manner as in Example 1, the composition further added with lotus germ extract powder was evaluated. In addition, as a plant material, a lotus germ extract powder (containing lotus germ extract 25%) known to have a beautifying effect was used. The blending and evaluation results are shown in Table 3 and Table 4.

It was found that discoloration of free ascorbic acid blended with a collagen peptide became more severe when lotus germ extract powder was further added.
On the other hand, it was found that the collagen peptide containing ascorbic acid sodium salt or calcium salt was inhibited from discoloration even when lotus germ extract powder was further added.

  Moreover, it was confirmed that the molecular weight of the collagen peptide is preferably 3000 or more from the viewpoint of the discoloration inhibiting effect even in the system further added with lotus germ extract powder.

  In the same manner as in Example 1, the blending ratio of collagen peptide, sodium ascorbate and lotus germ extract powder was changed, and the stability was evaluated. Table 5 shows the blending and evaluation results.

Here, the blending ratio of collagen peptide and sodium ascorbate is
(29) 1: 1
(30) 12: 1
(31) 60: 1
It is.

  As a result, it was confirmed that a composition having excellent stability could be obtained within the range of the blending ratio of 1: 1 to 60: 1.

  Based on the knowledge of Examples 1 to 3, tablets were prepared with the formulations shown in Table 6.

  Collagen peptide 200 mg, vitamin C 23 mg, and lotus germ extract powder 42 mg were blended, and excipients were added to obtain 300 mg core tablets. Tableting was performed using HT-AP22SS-II manufactured by Hata Plant.

  The prepared tablets were coated with hydroxypropylmethylcellulose (HPMC) and titanium oxide as main ingredients. The coating was performed using a Doria coater DRC-1400DS manufactured by POWREC.

The storage stability was evaluated using the tablets (core tablets and coated tablets) prepared in Example 4.
The tablets were stored in a plastic petri dish for 48 hours in a constant temperature bath at 40 ° C. and 75% RH.
Alternatively, the tablets were stored for 2 months in a thermostatic bath at 40 ° C. and 75% RH in a plastic bottle (made of HDPE, containing a desiccant, tightly plugged).

The color difference after storage was determined by calculating ΔE (a * b *) using the Hunter equation.
The results are shown in Table 7.
In any sample, discoloration was remarkably suppressed and stable.

  Based on the knowledge of Examples 1 to 3, tablets were prepared with the formulations shown in Table 8.

  Collagen peptide 200 mg, sodium ascorbate 11.5 mg, calcium ascorbate 11.5 mg, and lotus leaf extract powder 17 mg were blended, and excipients were added to obtain 300 mg core tablets. Tableting was performed using HT-AP22SS-II manufactured by Hata Plant.

  The prepared tablets were coated with hydroxypropylmethylcellulose (HPMC) and titanium oxide as main ingredients. The coating was performed using a Doria coater DRC-1400DS manufactured by POWREC. Both the obtained uncoated tablet and the coated tablet had no problem with discoloration during storage.

<Preparation of lotus extract powder, lotus root extract powder>
Lotus seeds or lotus roots were crushed, and the crushed material was immersed in 50% by weight ethanol of 8 times the weight of each dried product, and extracted at room temperature for 3 days. In addition, the dry matter weight of the crushed material was the weight when the constant weight was reached at 105 ° C. The filtrate after filter paper filtration was concentrated under reduced pressure and then lyophilized to obtain an extract. Three times the amount of dextrin was mixed with the weight of each extract to obtain a lotus seed extract powder or a lotus root extract powder.
<Evaluation>
Various collagen peptides, various vitamin C, cellulose, or various lotus extract extract powders were weighed according to a predetermined composition, mixed in a plastic bag 30 times. Each mixed powder is divided into 2 g plastic bags (100 x 70 x 0.04 mm) with a chuck and stored in a constant temperature bath at 45 ° C and 75% RH for 48 hours, and the appearance change of the powder is measured with a colorimeter (color difference) (The meter uses SpectroColorMeter SE2000 manufactured by Nippon Denshoku Industries Co., Ltd.). The difference between the starting sample and the sample stored at 45 ° C. and 75% RH was obtained by calculating ΔE (a * b *) using the Hunter equation.

  The blending and evaluation results are shown in Table 9 and Table 10.

  From the results shown in Table 9, it was confirmed that the sample containing free ascorbic acid and collagen peptide was significantly discolored. The discoloration was more pronounced when the molecular weight of the collagen peptide was lower, particularly when a collagen peptide having a molecular weight of 1500 was used.

It was also confirmed that the discoloration was remarkably suppressed when the sodium salt of ascorbic acid was used compared to the case where free ascorbic acid was used.
Moreover, 2000-20000 are preferable and, as for the molecular weight of a collagen peptide, 3000-20000 are especially preferable from the point of the discoloration suppression effect.

Table 10 shows the blending and evaluation results for the composition further added with lotus seed extract powder or lotus root extract powder.
It was found that discoloration of the collagen peptide containing sodium ascorbate was suppressed even when lotus seed extract powder or lotus root extract powder was further added.

Production example: drink agent Ascorbate sodium 1g, collagen peptide (molecular weight 5000) 12g, lotus germ 2.5g is weighed, sucrose 40g, sucralose 0.06g, acesulfame potassium 0.1g, citric acid 7g I took it.
