Description

  The present invention relates to a health food containing processed kale, pine bark extract, brown sugar, and water-soluble dietary fiber. Furthermore, the health food of the present invention relates to a health food excellent in palatability by suppressing a reduction in the effect of a pine bark extract such as antioxidant activity.

In recent years, many attempts have been made to prevent lifestyle-related diseases and aging by improving food. In particular, in order to improve the current eating habits, which tend to be mainly meat eating, it is recommended to take vegetables and dietary fiber actively. A green juice made from green leaves such as wheat leaves and kale has been developed as a food for easily taking dietary fiber, and its demand is expanding. (For example, patent document 1). In addition, as an ingredient for preventing aging, intake of polyphenols having antioxidant activity is recommended, and among them, pine bark extract is preferably used because it contains polyphenols having high antioxidant activity (for example, patents). Reference 2). Combining such a pine bark extract and kale as a health food allows easy intake of dietary fiber, and is expected to have antioxidative activity and the like that each of the pine bark extract and kale processed product has.

However, it has been found that simply blending a processed kale and a pine bark extract has a problem that the antioxidant activity and other effects of the processed kale and the pine bark extract are offset. Extracts have a unique astringent taste, and kale has a unique raw odor, making it difficult to use as a food in combination.
Therefore, the present inventors conducted extensive studies on the above combinations, and by adding brown sugar and water-soluble dietary fiber to food containing polyphenol-containing pine bark extract and kale processed product, It has been found that the effects of antioxidant activity and the like possessed by the processed kale and pine bark extract are prevented, the palatability as food is improved, and the food is easy to ingest as food.

  That is, the present invention relates to a health food comprising a processed kale product, a pine bark extract, brown sugar, and water-soluble dietary fiber.

  More preferably, the present invention relates to a health food containing 0.1 to 20 parts by weight of a pine bark extract with respect to 100 parts by weight of the dry weight of the processed kale.

  According to the present invention, by adding brown sugar and water-soluble dietary fiber to the processed kale and pine bark extract, the unique flavor of the processed kale and pine bark extract is improved, and the processed kale and pine bark extract The combination with the product can improve the palatability without reducing the antioxidant activity and the like. As a result, not only dietary fiber can be easily ingested, but also a health food excellent in antioxidant activity and excellent in flavor is provided.

  The present invention will be described below. Note that the configuration described below does not limit the present invention and can be variously modified within the scope of the gist of the present invention.

(A) Kale processed product In this specification, the kale processed product refers to a dry kale powder, a kale fragmented product and a dry powder thereof, a kale juice and a dry powder thereof, an extract of kale and a dry powder thereof.

  As a raw material of the processed kale used in the present invention, for example, various types of kale such as kitchen kale, tree kale, bush kale, mallow kale, collard, and green leaf kanran can be used. These kales are preferably processed immediately after harvesting. When time is required for processing, it is preferably stored by storage means commonly used by those skilled in the art, such as low-temperature storage, in order to prevent deterioration of kale.

  Moreover, in this invention, any part of the leaf part of a kale and a stem part is applicable.

  For example, the kale is used after being harvested, washed with water, drained and processed as it is, or cut to an appropriate length (for example, 5 cm) and processed.

  Further, the kale may be cut into pieces. The fragmentation can be performed by a method of fragmenting a plant body such as slices and shreds that are commonly used by those skilled in the art. The fragmentation includes slurrying. Slurry is performed by a mixer, a juicer, a blender, etc., and the kale becomes a mushy bowl (liquid and solid suspension). Kale juice obtained by squeezing after stripping can also be used. Squeezing can be done by centrifuging and / or filtering the minced kale.

  In order to maintain the quality of the processed kale, it is preferable to perform a process (branching process) for preventing the quality of food (including discoloration such as discoloration). For the blanching treatment, various methods are used depending on the form to be treated, and examples thereof include hot water treatment and steam heat treatment. By this treatment, the kale processed product does not change in amber color and flavor.

  The hot water treatment is performed, for example, by immersing kale in hot water containing sodium chloride and sodium bicarbonate. By adding appropriate amounts of sodium chloride and sodium bicarbonate alone or in combination in this way during the hot water treatment, a processed kale with vividly maintained green color can be obtained. In one embodiment, kale fragments, juices and extracts are treated at 80-150 for 2 to 180 seconds at normal pressure or under pressure or at reduced pressure.

  The processed product of kale thus obtained may be used as it is, or may be further shredded, squeezed and extracted to obtain a food material, or may be further powdered into a food material.

  Drying is performed such that the water content is 10% or less, preferably 5% or less, and further pulverized as necessary to obtain a dry powder.

  As a drying method, any drying method such as hot air drying, high-pressure steam drying, electromagnetic wave drying, freeze drying, and spray drying can be used. Drying is preferably performed at as low a temperature as possible, and even when heated to dry, for example, 30 to 90 ° C, preferably 40 to 60 ° C is preferable. After adding an excipient such as dextrin, cyclodextrin, starch or maltose, it can be spray-dried or freeze-dried.

  The pulverization can be performed according to a method commonly used by those skilled in the art, for example, using a crusher, a mill, a blender, a stone mortar or the like. The dry powder obtained by pulverization is sieved as necessary, and for example, one passing through a 30-250 mesh sieve is used. If the particle size is smaller than 250 mesh, it may be difficult to further process the food material or pharmaceutical material. If the particle size is larger than 30 mesh, uniform mixing with other food ingredients is prevented.

  The kale obtained as described above is further sterilized by any technique known to those skilled in the art, such as ordinary air sterilization treatment, high-pressure sterilization treatment, microwave treatment, heat sterilization treatment, etc., if necessary. obtain. The kale dry powder is obtained by pulverizing kale into a dry powder without fragmenting or extracting. The kale juice is, for example, the kale itself or one that has been squeezed into a squeezed product at the stage of fragmentation, and the one obtained by drying and pulverizing this is kale juice powder.

(B) Pine bark extract The pine bark extract in this specification contains proanthocyanidins containing flavan-3-ol and / or flavan-3,4-diol as a structural unit, and the degree of polymerization is particularly 2 -4 and low degeneracy proanthocyanidins (oligomeric proanthocyanidins; hereinafter simply referred to as OPC). OPC is a kind of polyphenol, a powerful antioxidant produced by plants, and concentrated in the leaves, bark, fruit peels or seed parts of plants. OPC is a substance that cannot be produced in the human body.

  As the pine bark extract used in the present invention, one containing a large amount of a condensation polymer having a low polymerization degree is preferably used. The condensation polymer having a low polymerization degree is preferably a condensation polymer having a polymerization degree of 2 to 30 (2 to 30 mer), more preferably a condensation polymer having a polymerization degree of 2 to 10 (2 to 10 mer). Further, a condensation polymer having a degree of polymerization of 2 to 4 (2 to 4 mer; that is, OPC) is more preferable.

Pine bark used for extracts rich in OPC includes Pinus Martima, larch, black pine, Japanese red pine, Japanese pine, Japanese pine, Korean pine, high pine, Ryukyu pine, Utsukushima, Japanese pine, white pine, and Quebec from Canada A bark extract of a plant belonging to the order of Pinaceae such as local Aneda is preferably used. Among them, French coastal pine (Pinus
Martima) bark extract is preferred.

  French coastal pine is a marine pine that grows on the Atlantic coast of southern France. The bark of French coastal pine contains proanthocyanidins, organic acids, and other physiologically active components, and the main component, flavonoid proanthocyanidins, has a strong antioxidant action to remove active oxygen.

  The pine bark extract is obtained by extracting the pine bark with water or an organic solvent. When water is used, warm water or hot water is used. As an organic solvent used for extraction, an organic solvent that is acceptable for the production of foods or drugs is used. For example, methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, butane, acetone, hexane , Cyclohexane, propylene glycol, hydrous ethanol, hydrous propylene glycol, ethyl methyl ketone, glycerin, methyl acetate, ethyl acetate, diethyl ether, dichloromethane, edible fats and oils, 1,1,1,2-tetrafluoroethane, and 1,1, 2-trichloroethene is mentioned. These water and organic solvent may be used alone or in combination. In particular, hot water, hydrous ethanol, and hydrous propylene glycol are preferably used.

  A method for obtaining an extract of pine bark is not particularly limited, and for example, methods that can be used by those skilled in the art such as a warm extraction method and a supercritical fluid extraction method can be employed.

  The extraction from pine bark may be a combination of these multiple extraction methods. By combining a plurality of extraction methods, it becomes possible to obtain pine bark extracts having various compositions.

  Specifically, the pine bark extract used in the present invention is prepared by the following method, but this is illustrative and is not limited to this method.

  1 kg of French maritime pine bark is placed in 3 L of a saturated solution of sodium chloride and extracted at 100 ° C. for 30 minutes to obtain an extract (extraction process). Thereafter, the extract is filtered, and the resulting insoluble material is washed with 500 mL of a saturated solution of sodium chloride to obtain a washing solution (washing step). The extract and washing solution are combined to obtain a crude extract of pine bark.

  Next, 250 mL of ethyl acetate is added to the crude extract and the phases are separated to recover the ethyl acetate layer 5 times. The collected ethyl acetate solutions are combined and added directly to 200 g of anhydrous sodium sulfate for dehydration. Thereafter, the ethyl acetate solution is filtered, and the filtrate is concentrated under reduced pressure until the original volume is reduced to 1/5. The concentrated ethyl acetate solution is poured into 2 L of chloroform, and the resulting precipitate is collected by filtration. Thereafter, the precipitate is dissolved in 100 mL of ethyl acetate, and then added to 1 L of chloroform again for precipitation to perform a washing step of repeating twice. By this method, for example, about 5 g of pine bark extract containing 20% by weight or more of 2- to 4-mer OPC and containing 5% by weight or more of catechins can be obtained. In terms of safety, it is preferable to extract pine bark with hot water, ethanol, or a mixture thereof, and then extract it using a synthetic adsorbent (such as Diaion HP20).

(C) Brown sugar Another essential ingredient of the health food of the present invention is brown sugar. Brown sugar is a concentrate of juice obtained by boiling down juice such as sugar cane and sugar beet. Unlike refined sucrose and other sucrose, it is a sugar containing saccharide containing components other than sucrose, so-called molasses. Moreover, only the molasses of a by-product produced when manufacturing super white sugar may be sufficient. Moreover, as a form, it is preferable that it is a powder form. The brown sugar used in the present invention preferably has a high molasses content. This is because molasses not only has a high palatability but also contains about 5 to 20% by weight of non-saccharide components such as vitamin B1, B2, magnesium, potassium, etc., so that the nutritional value of the health food of the present invention is increased. Because.

(D) Water-soluble dietary fiber The health food of the present invention further contains water-soluble dietary fiber. The above (A) green leaf powder contains dietary fiber, most of which is insoluble dietary fiber. Therefore, by containing water-soluble dietary fiber, the ratio of water-solubility and insolubility can be improved, and actions such as absorption and excretion of nutrients in the intestinal tract can be changed. Is considered to be easily obtained.

  Examples of the water-soluble dietary fiber used in the dietary fiber of the present invention include pectin, guar gum, psyllium, galactomannan, xyloglucan, locust bean gum, glucomannan, sodium alginate, chondroitin sulfate, low molecular weight alginic acid, low molecular weight guar gum, indigestible Dextrin, polydextrose, pullulan, fipalon, chondroitin sulfate and the like. In addition to these refined products, other food materials containing a large amount of water-soluble dietary fiber are also used as the water-soluble dietary fiber of the present invention. Of these, indigestible dextrin is preferably used.

(Health food of the present invention)
The pine bark extract contained in the health food of the present invention is preferably contained in an amount of 0.1 to 20 parts by weight, more preferably 1 to 10 parts by weight, based on 100 parts by weight of the dry weight of the processed kale. If the amount is less than 0.1 parts by weight, it is difficult to obtain an effect such as the antioxidant activity of the pine bark extract. However, it is difficult to improve the palatability.

  The brown sugar is preferably contained in an amount of 2 to 50 parts by weight, more preferably 5 to 30 parts by weight based on 100 parts by weight of the dry weight of the processed kale product of the present invention. If the amount is less than 3 parts by weight, the decrease in the antioxidant activity of kale and pine bark extract cannot be suppressed. If the amount is more than 30 parts by weight, the effect of brown sugar corresponding to the content cannot be obtained. It will be too high.

  Furthermore, the water-soluble dietary fiber is preferably contained in an amount of 50 to 500 parts by weight, more preferably 100 to 300 parts by weight, with respect to 100 parts by weight of the dry weight of the processed kale. The reason why such a range is preferable is that if the amount of water-soluble dietary fiber is less than 100 parts by weight, it may not be possible to prevent a decrease in blood antioxidant activity as in the case of brown sugar. Moreover, when there are more water-soluble dietary fibers than 300 weight part, the passage time of an intestinal tract becomes too early, and absorption may be inhibited instead.

  That is, the ratio of brown sugar and water-soluble dietary fiber added to the processed kale and pine bark extract is 0.4 to 100 parts by weight, preferably 1.5 parts by weight to 100 parts by weight of water-soluble dietary fiber. It is preferable to contain so that it may become 30 weight part.

  The health food of the present invention containing each of the above components can be used as it is or mixed with excipients, extenders, binders, thickeners, emulsifiers, colorants, fragrances, food additives, seasonings and the like. obtain. For example, as a nutritional supplement, royal jelly, vitamins, protein, chitosan, lecithin and the like are blended, and a sugar solution and seasoning can be further added to adjust the taste. These can be formed as hard capsules, soft capsules such as soft capsules, tablets, or pills, or in the form of powders, granules, baskets, or the like, as necessary. These may be eaten as they are or may be drunk in water, hot water, milk or the like according to the shape or preference. In addition, although there is no restriction | limiting in particular in the intake of the health food of this invention, It is preferable to take 0.5-15g of intake per adult on the dry weight of a kale dry powder.

  Hereinafter, the present invention will be described with reference to examples, but it goes without saying that the present invention is not limited to these examples.

(Example 1: Preparation of food)
Pine bark extract (toyo Shinyaku Co., Ltd.), brown sugar (Ueno Sugar Co., Ltd.) and water-soluble dietary fiber (indigestible dextrin, Matsutani Chemical Co., Ltd.) containing 40% by weight of dry Kale powder and OPC Company) and reduced maltose were used, and mixed powders 1 to 6 were prepared in the amounts shown in Table 1 and dissolved in 10 mL of water. In Table 1, “-” indicates that the corresponding component is not added.

(Example 2: Blood SOD activity test)
Using the above mixed powders 1 to 6, the SOD activity in blood was measured as follows.

  After acclimatizing 18 male rats aged 7 weeks with basic diet (MF diet, Oriental Yeast Co., Ltd.) for 1 week, fasted for 16 hours, blood was collected from the tail vein, and SOD measurement kit (SOD Test Wako, Wako Pure Chemical Industries, Ltd.) and divided into 6 groups so that the average values were the same. Subsequently, the solution containing each of the mixed powders 1 to 6 was orally administered with a sonde so as to have a body weight of 10 mL / kg, blood was collected again 45 minutes after administration, SOD activity was measured, and SOD activity relative to that before administration. The increase rate was calculated by the following [Equation 1]. The results are shown in Table 2. The values are average values.

  From the results of Table 2, the SOD activation ability of the mixed powder 4 containing the kale dry powder and the pine bark extract is almost the same as the mixed powder 3 containing only the pine bark extract, but only the kale dry powder is used. It can be seen that the SOD activation ability of the mixed powder 2 contained is lowered. From this, it can be seen that the SOD activation ability of kale and pine bark extract is inhibited by using a mixture of the dry kale powder and the pine bark extract. On the other hand, the mixed powder 1 of the present invention restores the SOD activation ability which was suppressed in this mixture by adding brown sugar and water-soluble dietary fiber to the mixture of the kale dry powder and the pine bark extract. I understand that. That is, it can be seen that the health food of the present invention has an excellent blood antioxidant effect when taken.

(Example 3: Evaluation of palatability)
The foods 1 to 4 (granular products) listed in Table 3 below are manufactured, 3 g of each food is dissolved in 100 mL of water to prepare a beverage, and this panel is tasted by five panelists. About whether it is preferable, unfavorable, or neither. The results are shown in Table 4.

  From the results of Table 4, it can be seen that the food of the present invention is most preferable from the aspect of palatability. Panelists also commented that the unique astringent taste of pine bark extract and the peculiarity of kale were greatly improved, making it easier to drink.

The health food of the present invention contains a processed kale, pine bark extract, brown sugar, and water-soluble dietary fiber, and suppresses a decrease in antioxidant activity in blood of the processed kale and pine bark extract. It can be used as a health food with excellent palatability.
