The drink containing date palm puree is obtained by adding Phoenix dactylifera with 3 to 4 times its weight of water, extracting at 100 to 120deg.C for 30min to 3hr, cooling to 70 to 95deg.C, removing seed and skin, mixing with 0.1 to 2% by weight of citric acid and sterilizing at 70 to 95deg.C for 30sec to 5min and homogenizing at 50 to 200kg/cm^2.

Description

Liquid preparation containing date palm}

Figure 1 is a schematic of the manufacturing process of the date palm drink containing the date palm extract according to the present invention.

The present invention relates to a date palm drink having a date as a main ingredient and a method of manufacturing the same.

The date palm is a fruit of the date palm Phoenix dactylifera L. native to western Asia and North Africa. The fruit is a round or long oval of 3-5cm, ripened from green to yellow to red, sweet and rich in nutrients. Rather than being a favorite, it is used as an important food resource to sustain life and is thought to be a gift from God.

The nutritional value of edible parts of the dried dates, except seeds, is the most carbohydrate (73%), mainly composed of fructose, glucose and sugar, and relatively low in protein and lipids (3%, 0.5%, respectively) and crude fiber 5.2% Listen. It also contains more phosphorus, iron, calcium and vitamins A, B1, B2 and B12 than any other fruit. In addition to its high nutritional value, folk medicine is known for its effects on asthma and bronchitis, good for blood circulation, warming the body, renowned as a tonic, and converting the body into an alkaline constitution.

Ingestion is usually done by chewing the seeds and eating them. The fruit is pressed into syrup and used as a sweetener. Whenever it is needed at home, a small amount of date palm is boiled with water to drink. U.S. Pat.Nos. 5,853,488 and 5,958,500 disclose the process of extracting fructose, sugar and glucose from date palms and using them as sweeteners. However, the process here involves freezing and grinding the extracted seeds from date palms. This is only possible if there is a complicated and expensive device for contacting hot water to extract sugars.

Nowadays, it is difficult to find the case where jujube drink is produced industrially and distributed anywhere in the world, as well as the problem of making tea every time as mentioned above. Because it is not contained, it is possible to store the one prepared in a high concentration syrup phase, but liquid formulations containing dates of appropriate concentration for drinking have a big problem because of the microbial propagation.

Accordingly, an object of the present invention is to solve the conventional problems as described above, the date palm water can be made to drink the date palm drink when necessary, and at the same time to enable hygienic and economical production of date palm drink It is to provide an extract or jujube palm puree using jujube water extract or jujube palm puree.

In order to achieve the above object, the date palm drink of the present invention removes only the minimum waste from the date palm extract or date palm extracted only the components soluble in water from the date contained in the date palm using the largest decorative part To prepare a puree, it is characterized by producing a date palm drink by mixing an appropriate amount of additives to the date palm extract or date palm puree thus prepared.

The present invention is characterized by the production of date palm drink using the production of date palm extract, date palm puree, date palm water extract or date palm puree.

First, the production of date palm water extract will be described.

As shown in FIG. 1, the date of the date palm is washed with water, and 3 to 10 times the weight of purified water is added to the date, and then 85 to 120 ° C. in an automatic extractor that can be pressurized to retain the flavor of the date. Heat extraction from 1 hour to 3 hours. At this time, it is more effective to extract the date palm inside the stirring if possible.

After heating, it is cooled to 70 to 80 ℃ and filtered to be used as a raw material for the production of date palm drink, or concentrated to remove the water to prepare a brine extract extract concentrate of 60 Brix.

Drink using jujube water extract is added to sterile purified water to the above jujube water extract to adjust the sugar content to 5 to 50 briquettes to be appropriate for drinking, citric acid 0.1 to 2%, sodium bicarbonate 0.01 to 0.1% After adjusting to hydrogen ion concentration 3 to 5 by addition, it is filtered using a filter paper of 0.2 to 3 μm, then aliquoted and sealed in a container and sterilized for 10 to 15 minutes at 120 to 125 ℃ in a sterilizer and packaged.

The date palm puree manufacturing process is as follows.

Selected date palms are washed with water, 3 to 4 times by weight of purified water, and extracted by pressing for 30 minutes to 2 hours at 100 to 120 ℃ to produce a soft date. Pass the stone brush (Pore size: 5 mm) and remove the pores (Pore size; 2 mm, 1 mm) continuously from the softened date palm to remove seeds, large hulls, and large fiber. To remove the shredded skin. Subsequently, the fine shell is removed by a centrifuge having a rotational speed of 4,500 rpm and a discharge time of about 5 minutes, and 0.1 to 2% of citric acid is added and mixed to adjust the pH of the hydrogen ion to pH 3 to 5 for good storage. The mixture is sterilized at 85 ° C. and rapidly frozen and stored at −18 ° C. or lower.

In the preparation of date palm drink using date palm puree, after thawing the date palm puree or frozen date palm puree before freezing, a mixture of organic acids such as citric acid is mixed and degassed. When the degassing process is complete, homogenize at 50 to 200 Kg / cm ² with a homogenizer, sterilize at 85 to 120 ° C for 30 seconds to 5 minutes, and fill and seal at 85 to 100 ° C. Complete the preparation of the beverage.

Alternatively, 1.5 to 2.5% by weight of vegetable cream powder, sucrose fatty acid ester and glycerin fatty acid ester, one or two or more emulsifiers selected from jujube palm puree, and purified water are added to emulsify and disperse 100 to 200 Kg / cm After homogenization at ² , retort sterilization at 115 to 125 ° C. for 5 to 15 minutes to complete the preparation of the 5 to 50 briquettes of date palm puree sugar.

Jujube drink of the present invention is characterized in that it uses the sweetness of natural date palm as it is without additionally added sweeteners, and since the date palm contains almost no organic acid, such as citric acid, tartaric acid, vitamin C, etc. It is characterized by adding an organic acid to make the liquid acid.

Hereinafter, the present invention will be described in detail with reference to examples, but the present invention is not limited to the described embodiments.
