Description

Abalone tofu and its manufacturing method {BEAN CURD USING ABALONE AND THE MANUFACTURING METHOD THEREOF}

The present invention relates to abalone tofu and a method of manufacturing the same, and more particularly, to abalone tofu that can help a lot of health promotion of modern people while minimizing nutrient destruction.

Soybeans are a very important crop economically all over the world, providing not only vegetable protein to people but also as a source of numerous chemicals.

These soybeans are rich in protein (40%), carbohydrates (30%), and lipids (20%). In particular, the soybeans are unsaturated fatty acids based on a fatty acid called linoleic acid. Therefore, there is no concern about arteriosclerosis and high blood pressure, and it is known to be good for preventing aging.

However, eating soybeans is almost indigestible, and is a substance called `` chio '' glycosides that cause illness in the thyroid, and other substances that interfere with the digestion of proteins, such as `` Kinitz '' inhibitors and `` Bowmann Burk '' inhibitors, and other blood cells. There are also some harmful substances such as agglomerates, so it is not eaten raw, but cooked or eaten tofu.

It is important to assess the quality of protein and how much can be consumed in the human body by consuming protein in food.

This is called net protein utilization (NPU). Tofu NPU is 65%, which is the same as chicken and higher than other soy products.

Tofu protein contains abundant lysine and evenly contains essential amino acids, which are deficient in other grains, so when mixed with foods that lack essential amino acids, it is very efficient in terms of nutritional value.

Tofu is a very soft and digestible food because it removes crude fiber and water-soluble carbohydrates contained in soybeans during the manufacturing process.

Tofu digestion is 95%, but roasted or boiled beans is about 68%. In addition, 216g of tofu has only 147 calories, while the same amount of eggs contains three times the calories and beef contains four to five times the calories.

Tofu is a protein food that is high in protein and low in calories and saturated fat and does not contain cholesterol, unlike other high protein foods.

Tofu contains about 15% saturated fatty acids and about 80% unsaturated fatty acids, especially linolenic acid.

On the other hand, beef has 48% saturated fatty acids and 47% low unsaturated fatty acids, and linolenic acid is only 9% among unsaturated fatty acids.

But linolenic acid, which is an essential fatty acid, cannot be synthesized in vivo, so it must be taken directly. Natural lecithin and linolenic acid present in the head metabolizes the accumulation of cholesterol and fatty acids in the intestine and blood in our body to disperse or eliminate it.

In the conventional manufacturing method of tofu such as protein and saponin in soybean ingredients are heated while heating soymilk, a large amount of bubbles are generated, and antifoaming agent is used to remove these bubbles, in particular, soybean immersion and soymilk heating. There is a problem that a lot of destruction occurs.

In the present invention to solve the above problems, while minimizing the destruction of nutrients and at the same time the nutrient components of abalone juice and walnut, chitosan, etc. in the tofu are mutually harmonized abalone tofu to help the health of modern people The purpose is to provide.

In the method for preparing abalone tofu of the present invention, after selecting abalone, the first step of preparing abalone pulverized product by pulverizing the abalone, and adding purified water to the prepared abalone crushed product, adding proteolytic enzyme, and then enzyme After the second step of producing the abalone enzyme digestion by digestion, the abalone extract is isolated by filtration of the prepared abalone enzymatic digestion, the third process to prepare the abalone extract by concentrating it, and then prepared by selecting soybeans, Soaked in water and then pulverized, it is boiled again and filtered to separate the soy milk and soy milk solution, and the separated soy milk solution is heated when the temperature of the soy milk solution is 65 ~ 70 ℃, and then diluted with a coagulant Then, the fifth step of preparing the tofu solid by adding the aged abalone juice, and the sixth step of preparing the tofu by pressing the tofu solid in a molding die.

In the preparation of the abalone enzyme decomposition product of the second step, the proteolytic enzyme is added to 0.5 ~ 1.0% by weight relative to the weight of the abalone crushed, and then the enzyme digestion of the proteolytic enzyme for 1 to 4 hours at 60 ~ 70 ℃ After the addition of 0.5 to 1.0% by weight of water, it is good to enzymatically decompose for 1 to 4 hours at 60 ~ 70 ℃.

When manufacturing the tofu solid of the fifth process, it may be prepared by further adding at least one selected from scavenger essence, chitosan.

The tofu of the sixth step is put into a mixed solution of soy sauce, deep sea water, herbs, abalone juice, low-temperature aging for 10 to 12 hours at 5 ~ 7 ℃, smoked may be prepared.

According to the present invention, the abalone tofu which can help a lot of health promotion of modern people by combining the nutritional ingredients of abalone juice, sauté, chitosan and the like in the tofu.

1 is a manufacturing method of abalone tofu of the present invention.

Beans contain a component called 'saponin', and excessive ingestion of saponin will cause the body to lose a lot of iodine.

Iodine is an important component of the thyroid gland, so when you eat a lot of soy products must be accompanied by foods that supplement iodine deficiency.

Therefore, in the present invention, tofu was made using abalone ingesting iodine-rich seaweed, and in particular, by adding smoked tofu, various food composition and shelf life of the tofu were increased, and ingredients such as stalks and chitosan were added to act as a natural preservative. By providing a safer food to consumers.

Hereinafter, the manufacturing method of the abalone tofu of the present invention will be described.

1) Step 1: Preparation of abalone crushed products

Abalone is first sterilized, washed, and then prepared separately from shells.

Thereafter, the abalone is pulverized for the purpose of enzymatic digestion, thereby preparing an abalone pulverized product.

Abalone is rich in protein and vitamins and has been treated as a high-grade seafood since ancient times. It has excellent effects on skin care, nourishing tonic, postpartum cooking, weak constitution, and zinc lowers blood sugar and leads to heavy metals. It is also known to be useful for excretion outside the body, and is known to be particularly effective for fatigue of the optic nerve.

2nd step: Preparation of abalone enzyme digest

After adding purified water to the prepared abalone crushed product, proteolytic enzyme was added, followed by enzymatic digestion to prepare abalone enzyme digest.

At this time, the purified water is good to put about 2 to 3 times the weight of the abalone crushed.

In addition, the protease is added to 0.5 ~ 1.0% by weight relative to the weight of the prepared abalone pulverulent, it is preferable to produce the abalone enzyme digestion by enzymatic degradation at 60 ~ 70 ℃ for 1 to 4 hours.

At this time, one selected from Acalase, Neutrase, Protamex, and Flavorzyme is used as a protease.

3rd process: abalone juice preparation

After filtering the prepared abalone enzymatic digestion to separate the abalone extract, and concentrated to prepare the abalone extract.

At this time, it is good to concentrate at 70 ~ 80 ℃.

4) 4th process: Separation of bean curd and soymilk

After the soybeans are prepared by selection, they are soaked in water and crushed, and then boiled again and filtered to separate bean curd and soy milk.

At this time, soybeans are expanded to a volume of two or more times the dry soybeans so called, so that the beans are soaked in water at 20 ~ 25 ℃ enough to immerse more than two times over the water surface.

Then, it is prepared for 8-9 hours in spring, autumn, 5 hours in summer, and 24 hours in winter. When the beans are called more than the above times, the fiber is excessively blown to block the filter net so that the bean water is completely removed. It is difficult to disadvantage and less than the above times because the soybeans are not completely comminuted and the amount of separated soybeans is reduced.

5th process: manufacturing tofu solids

The separated soymilk solution is heated when the temperature of the soymilk solution is 65 to 70 ° C., a coagulant is added thereto, and then the abalone juice is added to mature to prepare a tofu solid.

At this time, the abalone juice is preferably 0.2 to 0.5% by weight based on the weight of the soymilk.

As the coagulant, one selected from magnesium chloride and calcium sulfate is used.

In addition, the preparation of the tofu solids may be prepared by adding at least one selected from scavenger essence and chitosan, wherein the content of scavenger essence and chitosan is used by putting 0.1 to 0.5% by weight based on the weight of the abalone extract.

Here, the simmered juice is prepared in the same manner as the abalone juice.

Sasa borealis ) is generally proven to have a variety of physiologically active functions and because of its high alkalinity, it is also helpful in converting acidic to alkaline.

Poultry is rich in amino acids, such as polysaccharides such as xylose, aribinose, glucose, mannose, and galactose, aspartic acid, glutamic acid, seline, threninproline, and alanine chistein. In addition, it is rich in fat, calcium, silicic acid, vitamins B1 and K.

Chitosan (Chitosan) is a new substance that is easily absorbed by the human body of chitin, which absorbs and excretes excess harmful cholesterol, which acts as a decholesterol and inhibits the growth of cancer cells. It has an anticancer effect and has various effects such as inhibiting blood pressure increase and proliferating effective bacteria in the intestine and activating cells.

Such scavenger extract and chitosan in the present invention by providing a safer food to consumers by playing a role as a natural preservative, it is good to add 1 to 5% by weight relative to the weight of tofu solids.

6) 6th step: abalone tofu production

The tofu solid is put into a mold and pressed to prepare tofu.

At this time, the prepared tofu is placed in a mixed solution of soy sauce, deep sea water, herbs, abalone juice, low-temperature aging for 10 to 12 hours at 5 ~ 7 ℃, smoked may be prepared.

The mixed solution is preferably mixed with soy sauce, deep sea water, herbs and abalone juice 1: 1.5 ~ 2: 0.2 ~ 0.3: 0.5 ~ 1 weight ratio.
