ABSTRACT:
TECHNICAL FIELD
The present invention relates to processed food that is excellent in activating superoxide dismutase (hereinafter, referred to as SOD).
BACKGROUND ART
Young leaves of grass plants such as barley are rich in vitamins, minerals and dietary fibers, and are attracting attention as a material having the effects of adsorption of harmful substances, improvement of the intestinal environment, suppression of the absorption of cholesterol, prevention of a rapid increase in the blood glucose level after eating, etc.
On the other hand, in recent years, there have been an increasing number of reports that free radicals such as active oxygen cause a large number of diseases such as hypertension, cerebral stroke, myocardial infarction, pneumosclerosis, hepatitis, nephritis, atopic dermatitis, Parkinson's disease, cataracts, gout, pulmonary emphysema, dermatitis, gastritis, pneumonia, arthritis, stenocardia, senility, rheumatics, and arteriosclerosis. For example, it is known that when excessive active oxygen is present, normal cells are damaged and become cancer cells. At present, how to reduce such active oxygen is a serious issue to maintain our health.
In this context, health foods containing a material having SOD activities that eliminate active oxygen are commercially available. However, in view of the absorption rate of food, activation of SOD that exists in the body leads to more efficient elimination of active oxygen.
Therefore, there is a demand for health foods that activate SOD.
DISCLOSURE OF INVENTION
The inventors of the present invention conducted in-depth research on the activation of SOD and conceived the present invention as a result of finding that when young leaves of grass plants and powdered green tea are mixed, SOD that exists in the body can be activated better than when either one of them is used alone.
The present invention is directed to a processed food that is excellent in activating superoxide dismutase that contains grass plant young leaf powder and powdered green tea.
In a preferable embodiment, the processed food of the present invention further contains water-soluble dietary fibers, oligosaccharide, and lactic acid bacteria.
In a further preferable embodiment, the processed food of the present invention contains 30 to 70% by weight of grass plant young leaf powder, 1 to 50% by weight of water-soluble dietary fibers, 1 to 10% by weight of oligosaccharide, 0.5 to 5% by weight of lactic acid bacteria in the form of dry powder, and 5 to 15% by weight of powdered green tea.
In another preferable embodiment, the processed food of the present invention contains a calcium-containing substance and maltitol.
According to another aspect, the present invention is directed to a method for producing a processed food excellent in activating superoxide dismutase, including mixing grass plant young leaf power and powdered green tea.
In a preferable embodiment, the method further includes mixing water-soluble dietary fibers, oligosaccharide, and lactic acid bacteria.
In a further preferable embodiment, the method includes mixing 30 to 70% by weight of grass plant young leaf powder, 1 to 50% by weight of water-soluble dietary fibers, 1 to 10% by weight of oligosaccharide, 0.5 to 5% by weight of lactic acid bacteria in the form of dry powder, and 5 to 15% by weight of powdered green tea.
BEST MODE FOR CARRYING OUT THE INVENTION
“Grass plant young leaf powder” refers to powder from young leaves of grass plants such as barley, wheat, rye, oats or the like. Young leaves of the grass plant are obtained in the following manner, for example. Young leaves of a grass plant reaped in a period from the start of the branching stage to the early stage of the earring (when the height is about 20 to 40 cm) are washed with water or the like, and are cut to an appropriate length (for example, 10 cm). Then, a blanching (hot water) treatment, a microwave treatment, a treatment with steam or other treatments are performed to prevent the quality of the material from changing (e.g., fading of the green color or changing of the flavor), if necessary. Then, the leaves are dried until the water content is reduced to 5% or less, and are powdered. A short time blanching treatment is preferable for nutrient retention. For drying, lyophilization or drying by heating at a low temperature up to 70° C. (e.g., heating with warm air) is preferable. The obtained grass plant young leaf powder contains all the active ingredients of the leaves of the grass plant, because the powder is obtained simply by drying and powdering the leaves of the grass plant without any modifications.
Powdered green tea contains chlorophyll, carotene and amino acids such as theanine in a larger amount than green tea to be infused. Further, powered green tea contains less bitter ingredients such as catechin. However, powdered green tea, as well as green tea to be infused, is said to have the effect of suppressing cancer and many geriatric diseases, such as diabetes and hypertension.
The processed food comprising the grass plant young leaves mixed with the powdered green tea of the present invention can activate SOD that exists in the body. Furthermore, it is preferable to mix the processed food with other food materials, so that, for example, additional effects such as improvement of the taste and the flavor, and suppression of the absorption of cholesterol can be attained.
Examples of possible materials to be added include water-soluble dietary fibers, oligosaccharides, lactic acid bacteria, calcium-containing substances, and maltitol.
Young leaves of grass plants contain dietary fibers, which are mostly insoluble. Insoluble dietary fibers have the effects of preventing colon and rectum cancer and improving the intestinal environment. When the grass plant young leaf powder containing insoluble dietary fibers is mixed with water-soluble dietary fibers, the effects of suppressing the absorption of cholesterol, and suppressing an increase of the blood glucose level after eating, or other effects can be enhanced.
Examples of the water-soluble dietary fibers include alginic acid, indigestible dextrin, Guar gum hydrolysate, and glucomannan.
Oligosaccharides are generally assimilated by enterobacteria and improve the intestinal environment, and therefore oligosaccharides seem to have the same effects as insoluble dietary fibers, namely, the effects of preventing colon and rectum cancer and improving the intestinal environment.
Examples of oligosaccharides include lactulose, paratinose, fructo-oligosaccharides, raffinose, stachyose, xylooligosaccharides, maltooligosaccharides, isomaltooligosaccharides, trehalose, and galactooligosaccharides.
Similarly to oligosaccharides; lactic acid bacteria seem to improve the intestinal environment. Examples of lactic acid bacteria include
Lactobacillus acidophilus, Lactobacillus casei, Streptococcus faecalis
, and
Streptococcus thermophilus
. When using lactic acid bacteria, it is preferable to use them for powdered or liquid foods, and when the lactic acid bacteria are cultured in an appropriate medium, followed by lyophilization and added to processed foods, the lactic acid bacteria can be grown by providing moisture.
A preferable amount of grass plant young leaf powder to be mixed in a health food is 10% by weight to 90% by weight, more preferably, 30% by weight to 70% by weight, and more preferably, 30% by weight to 50% by weight.
A preferable amount of powdered green tea to be mixed is 3% by weight to 30% by weight, more preferably, 5% by weight to 15% by weight.
A preferable amount of water-soluble dietary fibers to be mixed is 1% by weight to 50% by weight, more preferably, 2% by weight to 40% by weight.
A preferable amount of oligosaccharide to be mixed is 0.1% by weight to 30% by weight, more preferably, 1% by weight to 10% by weight.
A preferable amount of lactic acid bacteria to be mixed is 0.1% by weight to 10% by weight, more preferably, 0.5% by weight to 5% by weight.
A preferable example of the mixing ratio of the mixture is 30% by weight to 70% by weight of grass plan
