Description

The present invention relates to a krill oil-containing composition in which the unpleasant odor of krill oil is reduced.

In general, supplements such as soft capsules containing health food materials can obtain a more stable bioactive function by continuously ingesting them on a daily basis. Soft capsules and the like help to make it easier to ingest continuously on a daily basis due to the effect of softening the odor and taste of the contained material, but in the case of a material having a strong odor, the odor may not be suppressed only by formulation.

For example, krill oil extracted from krill is sold as a supplement because it has various physiological activities. However, in addition to the original krill odor, krill oil has a peculiar odor due to trimethylamine, ammonia, etc. contained in a trace amount, which is unpleasant for some humans. In addition, the peculiar odor of krill oil may be further emphasized due to chemical changes such as oxidation over time. Therefore, a technique for preventing oxidation, which is one of the causes of the odor peculiar to krill oil, a technique for masking the unpleasant odor of krill oil, and the like have been studied (see, for example, Patent Documents 1 to 8).

[Discomfort evaluation method]
The degree of unpleasant odor is defined as "discomfort", and 10 subjects who feel unpleasant with the peculiar odor of krill oil show the degree of discomfort with the composition of the example and the krill oil alone of the comparative example in Table 1. Evaluated according to the criteria described in.
In addition, the standard of the degree of discomfort that can be tolerated by taking the supplement continuously every day was set to -1.8.

In Examples and Comparative Examples, "Superba 2" (manufactured by Aker Biomarin) was used as the krill oil.
Further, in the examples, when the total amount of krill oil is 100% by mass, the ratio of additionally blending the odor reducing substance is defined as "additional blending ratio (mass%)".
Further, in Tables 2 to 5, "%" means "mass%".

<Comparison example>
In the comparative example, 10 g of krill oil alone, which did not contain an odor-mitigating substance, was placed in a glass bottle and stored in a heat-retaining tank at 40 ° C. for 1 week in a closed state, and the degree of discomfort of the odor was evaluated according to the above evaluation method. The degree of discomfort in the comparative example was -1.9.

<Example 1>
The composition was adjusted by gradually changing the ginger extract to krill oil with an additional compounding ratio of 0.5 to 20% by mass. 10 g of each of these compositions was transferred to a glass bottle and stored in a heat-retaining tank at 40 ° C. for 1 week in a closed state, and the mixture was designated as "mixture 1 group".
Table 2 shows the evaluation results of discomfort for the above-mentioned "mixture 1 group". The degree of discomfort was the average of 10 subjects.
As the ginger extract, "SUN ginger" (manufactured by Sansei Pharmaceutical Co., Ltd.) was used. "SUN ginger" contains 0.5% by mass of ginger as a standard value.

In the "mixture 1 group" of krill oil and ginger extract, when the additional compounding ratio of ginger extract with respect to krill oil was 0.5% by mass or more, the standard to be tolerated as discomfort was -1.8 or more. Even with 20% by mass of ginger extract, the discomfort is sufficiently reduced, and from these tendencies, it can be expected that the discomfort can be reduced even if 20% by mass or more is added, but krill oil is used as a supplement without discomfort. Since the purpose is to ingest, no additional test of 20% by mass or more was conducted.

Since shogaol and gingerol contained in ginger extract are known to have anti-inflammatory effects, they can be expected to have additive and synergistic anti-inflammatory effects on knee joints and the like when taken at the same time as krill oil.

<Example 2>
The composition was adjusted by gradually changing the caramel to the krill oil from an additional compounding ratio of 0.5 to 20% by mass. 10 g of each of these compositions was transferred to a glass bottle and stored in a heat-retaining tank at 40 ° C. for 1 week in a closed state, and the mixture was designated as "mixture 2 group".
Table 3 shows the evaluation results of discomfort for the above-mentioned "mixture 2 group". The degree of discomfort was the average of 10 subjects.
"Homo caramel HC-30" (manufactured by Ikeda Saccharification Industry Co., Ltd.) was used for the caramel. "Homo caramel HC-30" contains 25% by mass of caramel as a standard value. The additional compounding ratio is a value based on the amount of caramel in "Homo Caramel HC-30".

In the "mixture 2 group" of krill oil and caramel, when the additional mixing ratio of caramel with respect to krill oil was 1% by mass or more, the standard to be tolerated as discomfort was -1.8 or more. Even with 20% by mass of caramel, the discomfort is sufficiently reduced, and from these tendencies, even if 20% by mass or more is added, it can be expected that the discomfort can be reduced, but ingestion of krill oil as a supplement without discomfort. Therefore, no additional test of 20% by mass or more was carried out.

Caramel is also used as a colorant for the film of soft capsules, and it can be expected to reduce the discomfort of krill oil by blending it into the film without directly mixing it with krill oil.

<Example 3>
The composition was adjusted by gradually changing the tea extract to krill oil in an additional blending ratio of 0.5 to 20% by mass. 10 g of each of these compositions was transferred to a glass bottle and stored in a heat-retaining tank at 40 ° C. for 1 week in a closed state, and the mixture was designated as "mixture 3 groups".
Table 4 shows the evaluation results of discomfort for the above-mentioned "mixture 3 group". The degree of discomfort was the average of 10 subjects.
"Coco Green GRSC" (manufactured by Pure Green Co., Ltd.) was used as the tea extract. "Coco Green GRSC" contains 50 mg or more of catechins in 100 g as a standard value.

In the "mixture 3 group" of krill oil and tea extract, when the additional content ratio of tea extract to krill oil was 4% by mass or more, the standard to withstand discomfort was -1.8 or more. At the additional compounding ratios of 10% by mass and 20% by mass, the degree of discomfort tended to increase slightly as compared with 5% by mass. It seems that the balance of the odors of krill oil and tea extract was lost due to the increase in tea extract, but even with the additional compounding ratios of 10% by mass and 20% by mass, the standard of 1.8 or more that can be tolerated as discomfort was maintained. ..

Since tea extract has an antioxidant effect, it improves the storage stability of krill oil, and for humans, it has an effect of lowering LDL cholesterol. Therefore, co-ingestion with krill oil improves vascular health. Can be expected to be effective.

<Example 4>
The composition was adjusted by gradually changing the boswellia serrata extract to krill oil with an additional compounding ratio of 0.5 to 20% by mass. 10 g of each of these compositions was transferred to a glass bottle and stored in a heat-retaining tank at 40 ° C. for 1 week in a closed state, and the mixture was designated as "mixture 4 groups".
Table 5 shows the evaluation results of discomfort for the above-mentioned "mixture 4 group". The degree of discomfort was the average of 10 subjects.
"Boswellia powder K" (manufactured by Nippon Shinyaku Co., Ltd.) was used for Boswellia serrata extract. "Boswellia powder K" contains 80% by mass of boswellic acid (mainly β-boswellic acid) as a standard value.

In the "mixture 4 group" of krill oil and boswellia serrata extract, when the additional compounding ratio of boswellia serrata extract to krill oil is 0.5% by mass or more, the standard that can be tolerated as discomfort is -1.8 or more. rice field. On the other hand, when the additional compounding ratio was 20% by mass, the discomfort tended to increase. It is believed that the increase in boswellia serrata extract to 20% by mass caused the odor balance between krill oil and boswellia serrata extract to become unbalanced, resulting in increased discomfort.

Boswellia serrata extract is known to have effects such as alleviating the symptoms of joint pain, so when taken at the same time as krill oil, it can be expected to have additive and synergistic anti-inflammatory effects on the knee joints, etc. ..

<Discussion>
As a result of the above, by adding at least one selected from ginger extract, caramel, tea extract and Boswellia serrata extract to krill oil rather than krill oil alone, the peculiar odor of krill oil is alleviated and ingested. It was confirmed that the discomfort when doing so was reduced.
