Particularly, the method of manufacturing sweet potato caramel according to the present invention is characterized in that it can provide sweet potato caramel that can maximize the content of sweet potato and enjoy taste and nutrition peculiar to sweet potato unlike the conventional sweet potato processed food.

This feature is produced by processing the sweet potato starch and heating the sweet potato. The sweet potato powder prepared by processing the sweet potato is mixed with the constant amount of the sweet potato powder at a predetermined time interval, and then processed into a gelatinized sweet potato caramel and then cooled to prepare a solid sweet potato caramel To complete the manufacturing process.

Hereinafter, a method of manufacturing sweet potato caramel according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a block diagram showing a step-by-step process for producing a sweet potato caramel according to a preferred embodiment of the present invention.

1, the method of preparing sweet potato caramel according to a preferred embodiment of the present invention includes steps of preparing a sweet potato powder (S100), preparing sweet potato sauce (S200), mixing heating (S300), and cooling and drying S400).

First, in preparing the sweet potato powder (S100), the sweet potato is processed into a powder having a predetermined particle size or less and prepared.

That is, in the step of preparing the sweet potato powder (S100), the sweet potatoes of high quality are selected, cleaned and then pulverized by a grinder to process the sweet potato powder.

To this end, the preparation step (S100) of the sweet potato powder may include a selection step (S110), a washing step (S120), a skin removing step (S130), a boiling step (S140), a drying step (S150) (S160).

The selecting step (S110) is a step of selecting sweet potatoes without scratches or scratches. However, when selecting sweet potatoes, it is important to select good quality sweet potatoes without scratches or scratches. However, it is very important to choose sweet potatoes as a sweet potato starch to facilitate processing into sweet potato powder. This is because sweet potatoes at night are relatively hard and have no water, so it is not difficult to powder them into the desired particle size.

The cleaning step (S120) is a step of cleaning the selected sweet potatoes cleanly. At this time, it is preferable to immerse the baking powder in water dissolved in the baking powder for a certain time so as to effectively remove harmful components such as pesticides on the sweet potato.

That is, the sweet potato may be immersed in the baking powder-dissolved water for a certain period of time and then cleaned with fresh water. At this time, it is possible to use not only baking powder but also an edible cleaning agent similar to the cleaning power of baking powder such as vinegar.

The skin removing step (S130) is a step of removing the skin of the washed sweet potato. That is, the shell is a process of removing the shell which is not easily pulverized due to the turbid color of the fiber.

The boiling step (S140) is a step of putting the peeled sweet potato into a container together with water, and heating and boiling. At this time, it is desirable to boil the sweet potato for 20 to 40 minutes so that the shape can be maintained at a certain pressure. However, if the size of the sweet potato is large, it is desirable to cut it to a certain size in order to shorten the boiling time.

In the drying step (S150), boiled sweet potatoes are extracted from water and dried at room temperature for 12 to 24 hours. This is to remove moisture as much as possible at room temperature, thereby facilitating pulverization in the subsequent milling step.

In the pulverizing step (S160), the dried boiled sweet potato is put into a pulverizer and pulverized to a predetermined particle size or less to be processed into a sweet potato powder. However, the sweet potato powder is preferably pulverized to a particle size of 50 to 70 mesh so that the sweet potato powder can smoothly penetrate into the sweet potato starch in the subsequent mixing and heating step (S300).

For this, it is preferable to repeat the grinding step (S160) at least once.

However, the dried boiled sweet potato is structured such that vibration is generated at a predetermined time interval in the pulverizing roller so that the sweet potato does not stick to the pulverizing roller when the pulverizer is pulverized and smoothly pulverized and freely falls. The pulverizing roller has a predetermined distance And a second crushing roller disposed at a predetermined distance from the first crushing roller and the second crushing roller.

Next, the preparing step (S200) of sweet potato preparation is a preparation step of processing the sweet potato into a gelatinized sweet potato preparation.

That is, the preparing step (S200) of sweet potato preparation is a process of selecting sweet potatoes of high quality, washing them cleanly, heating them, preparing them for a long time, and processing the sweet potato preparations.

The preparing step S200 of the sweet potato preparing step S200 includes a selection step S210, a cleaning step S220, a shell removal step S230, a boiling step S240, a fermentation step S250, an extraction step S260, S270).

The selecting step S210 is a step of selecting sweet potatoes without scratches or scratches. However, when selecting sweet potatoes, it is important to choose good quality sweet potatoes without scratches or scratches. However, it is very important to choose pumpkin sweet potatoes so that they can be easily processed into sweet potatoes. This is because zucchini sweet potatoes are characterized by the lack of meat quality and wateriness, so there is no difficulty in making them gelatinous.

The cleaning step S220 is a step of cleaning the selected sweet potatoes cleanly. At this time, it is preferable to immerse the baking powder in water dissolved in the baking powder for a certain time so as to effectively remove harmful components such as pesticides on the sweet potato.

The skin removing step S230 is a step of removing the skin of the washed sweet potato. That is, the shell is a process of removing the shell which is not easily pulverized due to the turbid color of the fiber.

The boiling step (S240) is a step of putting the sweet potatoes from which peel has been removed into water and boiling them until the water is completely cooked. In other words, it is preferable to boil the sweet potato for 2 ~ 3 hours so that it does not pressurize the sweet potato itself.

In the fermentation step (S250), the fermented milk is fermented at 60 to 80 DEG C for 8 to 12 hours by adding the malt liquor to the boiled sweet potato until crushed. At this time, it is preferable to mix the sweet potato and the malt solution in a weight ratio of 5: 2.

In the extracting step (S260), the fermented sweet potato and the malt liquor are put in a bag and pressed to extract the liquid. That is, except for the solid content of the fermented sweet potato, only fermented sweet potato juice and malt liquor are extracted in a liquid state.

The preparation step S270 is a step of heating the extracted ginseng and processing it into sweet potato starch. That is, it is a step of evaporating moisture from the extracted juice to obtain a thick liquid sweet potato juice. In this case, it is preferable to heat for 3 to 6 hours at a temperature at which the heating time varies depending on the moisture contained in the juice, but the juice does not burn.

Next, in the mixing and heating step (S300), the sweet potato starch is heated and mixed with the sweet potato powder to process the sweet potato caramel in a gel state.

That is, the sweet potato starch is a process in which sweet potato powder strengthens the binding force between the sweet potato powder and the caramel.

At this time, sweet potato starch and sweet potato powder are preferably mixed at a weight ratio of 1: 1. This mixing ratio is to make caramel-like shape possible while maximizing the content of sweet potato.

However, it is preferable to mix the sweet potato powder with the sweet potato powder at a temperature of 90 to 110 ° C for 1 to 2 hours at intervals of 10 minutes, and then heat the potatoes for 1 to 2 hours while stirring the sweet potato powder. So that it can be dissolved smoothly in the morning syrup.

Finally, in the cooling and drying step (S400), the processed gelatinized sweet potato caramel is cooled and then dried to complete the production of sweet potato caramel which is easily waxy and deformed in shape.

The processed gelatinized sweet potato caramel may be slowly dried at room temperature and then dried naturally or may be freeze-dried by being introduced into a freezer.

Hereinafter, a method for producing caramel sweet potato according to a preferred embodiment of the present invention will be described. In the mixed heating step (S300), lecithin extracted from isomaltooligosaccharide, white sugar, vegetable oil, whey protein, salt, emulsifier, , Gelatin extracted from pork, and natural pigments with caramel color.

The above-mentioned additives are added to the flavor, texture and color of sweet potato caramel in a manner similar to actual caramel, to further enhance consumers' need for eating.

In order to maximize the content of sweet potatoes, 40 wt% of sweet potato starch, 40 wt% of sweet potato powder, 5 wt% of isomaltooligosaccharide, 3 wt% of white sugar, 2 wt% of vegetable oil, 2% by weight of salt, 2% by weight of salt, 2% by weight of emulsifier, 2% by weight of lecithin, 1% by weight of gelatin and 1% by weight of natural pigment.

The above-described embodiments are merely illustrative, and various modifications may be made by those skilled in the art without departing from the scope of the present invention.
