Therefore, it is required to reduce the cholesterol and fat content in organs and blood vessels, and particularly to take foods that can improve the digestive function or help in the rectal action.

In this regard, onions or onion juice as a health food has recently been in the limelight.

Oniu (Alliurn cepa) is a perennial herbaceous plant of the genus Liliaceae, which is believed to originate in the West Asian or Mediterranean coasts, but it is not clear because no wild species have yet been found. The history of cultivation is so old that the frescoes of ancient Egyptian tombs around 3000 B.C. have recorded that garlic and onions were fed to the pyramid-laying workers, and in Greece they were cultivated from the 7th and 8th centuries BC. Onion varieties are divided into rounded and flat rounded scales, with red, yellow and white scales. Also, depending on taste, it is divided into mono onion and spicy onion. The varieties cultivated in Korea include chalcedony, cheonjuwang, horticulture 1, horticulture 2, aegean or shellfish.

Onions are mainly used for edible scales, and the unique smell of scales is known to be due to compounds such as propyl disulfide and aryl sulfide. These compounds physiologically promote the secretion of digestive fluid and have an effect such as excitement, sweating or diuresis. Reported to be present. In addition, the onion scales contain minerals such as calcium and phosphoric acid together with various vitamins, and are known to have a prophylactic or therapeutic effect such as eliminating harmful substances in the blood and reducing lipid components contained in the blood.

However, the improvement or prevention of hyperlipidemia has been proved in relation to metabolic diseases, which have recently been pointed out as a serious problem, and although it contains various physiologically active substances, onions have a specific effect. Odors, ie spicy taste and odor, have limited their use and use.

Therefore, in the production of a drink using onions having various effects including the improvement or prevention effect and diet effect for the metabolic disease, by improving the pungent taste and smell peculiar to onions to suit the taste of various people There is a growing market demand for products that can be consumed consistently.

In order to solve the conventional problems as described above, an object of the present invention is to use onions that are recognized in the blood lipid reduction effect and diet effect, by controlling the spicy taste and smell peculiar to onions easy to take the preparation method of the beverage To provide.

The inventor of the present invention has continued to study drinks using onions as a main ingredient, which is recognized various effects including blood lipid reduction effect and diet effect, and to reduce the bitter taste and pungent smell peculiar to onion for long-term use of onion drink While conducting research on the idea that it should be done, onions can be diluted with water or minimize the addition of sugars, such as sugar intake, such as sugar, to maintain functional effects such as onion's blood lipid reduction or diet effect. In order to reduce the characteristic bitterness and pungent smell, grapefruit with diet effect and blood lipid reduction effect are put together and steamed, then filtered, honey is added to the filtered juice and then stirred at high temperature. If you do, the bitterness and pungent smell of onions is significantly reduced, While improving the degree of preference, the present invention has been completed by confirming that minimizing additional additional processes is also helpful in improving productivity.

Hereinafter, the present invention will be described in more detail.

The present invention relates to a method for producing an onion grapefruit drink.

In the present specification, the onion grapefruit drink refers to a beverage prepared by the production method of the present invention with onion and grapefruit as the main ingredient, the beverage is juice or juice form does not add water separately in processing onion and grapefruit It is a concept that includes all the drinks and drinks prepared by adding additives in processing the onion and grapefruit.

In the present specification, onion (onion, Allium cepa L.) is a perennial herbaceous plant of the genus Liliaceae, which is believed to be native to West Asia or the Mediterranean, but is not yet known as no wild species have been found. Onions are mainly used for edible scales, and the unique smell of scales is known to be due to compounds such as propyl disulfide and allyl sulfide. Reported to be present. In addition, the onion scales contain minerals such as calcium and phosphoric acid with various vitamins. The onion is known to have a blood vessel strengthening effect and an antiallergic effect, the quercetin (Quercetin) contained in the onion is known to have an antioxidant effect, triglycerides and cholesterol reducing effect.

In the present specification, grapefruit (grapefruit, Citrux paradise ) is the fruit of the grapefruit tree belonging to the citrus (Citrus). The grapefruit tree is native to Jamaica, the West Indies. The grapefruit has a grape-like fragrance and runs like a cluster of grapes. For this reason, the English name is called grapefruit. The grapefruit is tangerine-shaped, ie spherical or scalloped, the outer skin is leathery and the surface is smooth and yellow. The inner skin is thin and soft, and the flesh is pale yellow, rich in juice, sweet and strong in taste, and bitter. It is usually processed into frozen juice and currently produces about 60% of global production in Florida. The grapefruit, in particular, the skin of the grapefruit is known to contain a large amount of naringin known to be excellent in antioxidant and lipid reduction effect.

In the present specification, honey (honey) is a natural sweetener, a natural sweetener that has been used by mankind for a long time. In both East and West, including Korea, honey has been widely used for medicinal and edible food. Honey is largely divided into honey (natural honey) and molasses (artificial honey).

The honey means that honey bees collect sweet honey powder (nectar honey) such as flower honey (flower honey) or plants or ticks and save and mature in honeycomb. In our country, honey usually refers to flower honey. The first collected from the flower is mainly a sugar component, but the components are changed to bee digestive enzymes, the components of the bee digestive enzymes are called honey. Honey is slightly different depending on the source of wheat, but it is generally 78% carbohydrate, 47% fructose, 37% glucose, digestible and good absorption. In addition, minerals, vitamins, formic acid, lactic acid, malic acid, pigments, fragrances, rubber, wax, pollen, etc. are included.

Method for producing an onion grapefruit drink of the present invention comprises the steps of washing the onion and grapefruit; Grinding the washed onion and grapefruit; Preparing onion grapefruit mixed juice by steaming the crushed onion and grapefruit in a predetermined condition; Filtering the onion grapefruit mixed juice; Adding honey to the filtered onion grapefruit mixed juice; And it relates to an onion grapefruit drink manufacturing method comprising the step of heating the honey is added onion grapefruit mixed juice.

The washing of the onions and grapefruit may be performed by a method including mixing onions and grapefruits and washing the mixed onions and grapefruits.

Mixing the onion and grapefruit may be carried out in a mixing ratio of 96: 3 to 98: 1, preferably 97: 2 based on the weight ratio. While the mixing ratio controls the unique pungent smell and bitter taste of onion due to the sour taste of grapefruit, it is preferable to adjust the content so that the palatability is not reduced by the sour taste peculiar to grapefruit or the peculiar taste such as the savory taste of onion juice is not reduced. Do.

The process of washing the onion and grapefruit is a process for removing soil, impurities or contaminants adhered to the onion and grapefruit, and does not remove the shell or perform a separate process. In the case of grapefruit, the outer shell contains the most abundant naringin, which is an active ingredient of grapefruit, and in the case of onion, the outer shell contains not only a large amount of quercetin, but also the shell and air, that is, oxygen In this case, sulfur compounds may be generated through the enzymatic reaction, causing the onion's characteristic irritating taste and odor. Therefore, the washing process may be performed only by washing with water, specifically, using soil water to remove soil or impurities.

Grinding the washed onion and grapefruit may be performed using a grinder or mixer. Since water is not added when the onion and grapefruit are ground, it is preferable to carry out the grinding sufficiently until the ground product becomes a thick porridge form, that is, a liquid phase.

The preparing of the onion grapefruit mixed juice may be performed by steaming the pulverized onion and grapefruit, specifically, the onion and grapefruit pulverized liquid, under certain conditions, preferably at 105 ° C. for 5 hours. In the steaming method, if steaming is performed at a too high condition, the palatability is reduced due to the burning smell of onion or grapefruit, and if steaming at a too low condition, steaming is not sufficiently performed, so that there is too much dust in the filtration step. The efficiency is lowered, or the spicy taste of onion and the sour taste of grapefruit do not combine, but rather has a disadvantage of decreasing the preference.

The filtering of the onion grapefruit mixed juice may be performed using a filter net or a brush. The filter net or brush is connected to the vibration structure, and by vibrating filtration, it is possible to increase the efficiency compared to the case of simply passing through the filter net.

The adding of the honey to the filtered onion grapefruit juice is a method of adding honey and stirring the content of 97: 1 (onion: honey) based on the weight of the onion mixed with the filtered onion grapefruit juice in the washing step It can be done with The honey may preferably be honey.

Heating the honey grapefruit mixed juice to which the honey is added may be carried out while heating and stirring at 120 ℃ for 1 hour. After the honey is added, the stirring step can exert the effect of dissolving and mixing the honey sufficiently and finally disinfecting the prepared onion grapefruit drink, further suppressing the spicy aroma and the freshness of grapefruit. Since the above step of the present invention can be economically advantageous effects are recognized.

Onion grapefruit mixed beverage prepared by the above method may be individually packaged and distributed in whole or divided into predetermined amounts.

In this aspect, the onion grapefruit beverage manufacturing method further comprises the step of individually packaging the onion honey grapefruit mixed juice to which the heated honey is added to a predetermined content after performing the step of heating the honey grapefruit mixed juice to which the honey is added. It may include.

The present invention may also be an onion grapefruit drink prepared by the onion grapefruit drink manufacturing method. The onion grapefruit mixed drink is not only easy to take the improved smell and bitter taste peculiar to onions, but also diluted with water or added to artificial sweeteners such as sugar, lipid reduction effect or dietary effect of onion Has the advantage that can be maintained or rather increased.

The onion grapefruit mixed beverage may be individually packaged or distributed in whole or divided into predetermined amounts.

The onion grapefruit blend drink is additionally nutrients, vitamins, electrolytes, flavors, coloring agents, neutralizing agents, pectic acid and salts thereof, alginic acid and salts thereof, organic acids, protective colloidal thickeners, pH regulators, stabilizers, preservatives, glycerin, The carbonation agent used for alcohol, a carbonated drink, etc. can be contained within the range which maintains the effect of this invention. The components can be added independently or in combination.
