JPH0722501B2 - Beverage containing Ginkgo biloba extract - Google Patents

Description

TECHNICAL FIELD The present invention relates to a beverage containing a ginkgo biloba extract.

[Conventional technology]

Ginkgo biloba extract is effective for vasodilation, increase in blood flow, prevention of aging of vascular system, etc., and is used for medical purposes, and it is also proposed to add it to a drink to make a health drink.
(JP 62-205028).

The problem with adding Ginkgo biloba extract to beverages is that it is difficult to stably dissolve Ginkgo biloba extract in the beverage because the Ginkgo biloba leaf extract is poorly soluble in water, and some of the added Ginkgo biloba extract may be stored during storage. It is easy to precipitate.

Ginkgo biloba extract dissolves well in ethanol-containing water, so ethanol is often used as a solvent when it is used in the form of a drug. It is easy to dissolve ginkgo biloba extract in alcoholic beverages with a high ethanol concentration, such as liqueurs, but it cannot be a general beverage.

[Problems to be Solved by the Invention]

Therefore, the present invention intends to provide a beverage which has a health effect and which anyone can drink, in which the ginkgo biloba extract is stably dissolved without utilizing the dissolving power of ethanol.

[Means for Solving the Problems]

The present invention, which succeeded in achieving the above object, provides a ginkgo biloba extract, which contains ginkgo biloba extract, sugar and sugar alcohol, and has a total soluble solid content concentration of Brix 20 to 32. Is.

In the beverage of the present invention, sugar and sugar alcohol impart sweetness to the beverage and increase the Brix degree to a required level to prevent precipitation of ginkgo biloba extract.

The ginkgo biloba extract contained in the beverage of the present invention is not particularly limited as long as it contains flavonoids extracted with hydrous lower alcohol and the like.

On the other hand, as the sugar to be contained in the beverage of the present invention, glucose, fructose, sucrose, maltose (syrup), water-soluble oligosaccharides or polysaccharides, or a mixture thereof can be used.

As sugar alcohols, tolbitol, maltitol,
Reduced maltose, reduced starch sugar, or a mixture thereof can be used.

Regarding the stabilizing effect of Ginkgo biloba extract in beverages,
Both sugar and sugar alcohol have almost the same potency (see Experimental Examples below). However, the sugar, which is often used as a sweetener, often causes the adverse effect that not only the sweetness is too strong but also the calorie content is too high when it is contained in the beverage at a concentration exceeding Brix20. On the other hand, sugar alcohols and oligosaccharides generally have a weak sweetness, so they cannot impart sufficient sweetness by themselves, and since they are generally indigestible, containing too high a concentration causes abdominal bloating and loose stools. . Therefore, in the beverage of the present invention, sugars having strong sweetness or normal calories are appropriately combined with unsweetened or low-sweetened sugar alcohols or soluble indigestible polysaccharides to give excessive sweetness and high calories. And to prevent discomfort caused by indigestion. In many cases, it is desirable to use indigestible sugars and sugar alcohols, that is, indigestible polysaccharides and sugar alcohols such that the total amount is 50% by weight of the total soluble solids.

The beverage of the present invention may contain fruit juice, acidulant, vitamins, flavors, colorants and the like, in addition to the above-mentioned components, if necessary.

When the beverage of the present invention is produced, the ginkgo biloba extract is dissolved in advance in a small amount of ethanol or hydrous ethanol, and the other beverage components are mixed, whereby a stable dissolved state can be easily obtained.

〔Example〕

Experimental Example 0.2 part of citric acid (weight part, the same applies hereinafter), 0.04 part of sodium citrate, 0.08 part of vitamin C and 0.03 part of sodium benzoate are dissolved in 30 parts of water to prepare a stock solution. To the above stock solution, 0.04 part of Ginkgo biloba extract was dissolved in a small amount of water-containing ethanol and added, and then various sugars or sugar alcohols were dissolved, and water was added to make the total amount 100 parts, and the Brix degree tail and stability were examined.

The stability is indicated by the amount of precipitate formed when visually observed after standing at 30 ° C. for 2 weeks. The more + there is, the more remarkable the precipitation is and the more unstable it is, and the-, the precipitation is not recognized at all. The results are shown in Table 1.

Example 1 Predetermined amount of starch syrup and reduced starch sugar, and vitamin C4
5 parts of Ginkgo biloba extract (used by dissolving it in a small amount of water-containing ethanol) was added to water in which 10 parts of acidulant, 25 parts of acidulant and 10 parts of fragrance were added, and water was further added to make a total of 10,000 parts. The results of examining the relationship between the Brix degree and the stability of the seven types of soft drinks as described above in the same manner as in the above experimental example are shown in Table 2.
It was as follows.

Example 2 Starch syrup (Brix75), reduced starch sugar (Brix70), and PD (polydextrose; Brix9) in the amounts (parts by weight) described in Table 3.
To the water obtained by dissolving 5), add 25 parts of acidulant, 10 parts of flavor, and 5 parts of ginkgo biloba extract (used by dissolving in 100 parts of 50% ethanol), and further add water to make the total amount 10,000 parts.

Seven Brx32 soft drinks were prepared as described above.
When the stability of the products was examined in the same manner as in the above experimental example, no precipitate formation was observed in any of the products.

In addition, the above soft drinks will be served daily by a panel of 30 people.
A drinking test of 50 ml for 1 week was performed. In each case, the sweetness was evaluated as moderate, but the ratio of indigestible sugars in the total solids was 50%.
%, Some people complained of abdominal distension, 70% of them complained of abdominal distension and squealing, and 2 more had loose stools.

〔The invention's effect〕

Since the beverage according to the present invention succeeds in stably dissolving the ginkgo biloba extract with only a specific amount of sugar or sugar alcohol without utilizing the dissolving power of ethanol or a surfactant, It is a beverage that has a health effect based on a pharmacological action, is easy to drink, and has excellent storage stability and safety.

Claims (2)
