Description

Salt processing method using sea cucumber hot water extract}

The present invention relates to a salt processing method using sea cucumber hot water extract. The sea cucumber boiled water generated during the manufacturing process of dried sea cucumber is used to process seaweed food, so it is environmentally friendly, contains a large amount of nutrients such as amino acids and saponins, and has excellent storage properties. This relates to a salt processing method using sea cucumber hot water extract.

Sea cucumber is a general term for sea cucumbers belonging to the class of sea cucumbers, which are echinoderms. It was named sea cucumber because its medicinal properties are similar to those of ginseng. Food-wise, sea cucumbers are composed of approximately 90.5% water, with the remaining 3.2% protein, 0.2% fat, and 3.5% minerals. The protein contained in sea cucumbers is of excellent quality, and minerals include calcium and phosphorus in appropriate proportions, and the cartilage area contains a lot of chondroitin sulfate.

In addition, as free amino acids, alanine, which gives a sweet taste, and glutamic acid, which gives a savory taste, are the most widely distributed, and the content of saponin, known as a functional ingredient of ginseng, is also high, so it is called sea ginseng. It is rich in calcium and iron, so it is good for teeth and skeleton. It is effective in the formation and normal contraction of muscles, and is rich in iodine and alginic acid, which promotes metabolism in the body and has the function of purifying the blood.

The body wall, which is the main ingestion part of the sea cucumber, is mainly composed of protein, and the protein contains collagen and the viscous polysaccharide fucose sugar, chondroitin sulfate, ganglioside, and glycosphingolipid. The collagen of sea cucumber is known to have a moisturizing effect that retains moisture, antioxidant activity, and a blood pressure reduction effect.

According to the academic world, the chondroitin in sea cucumbers provides nutrients to the cartilage of joints and allows the fluid that absorbs physical shock and stress to stay in the cartilage, increasing elasticity, preventing skin aging, and neutralizing poisons. Ganglioside It is reported to be active in the development of neurites, and in oriental medicine and folklore, sea cucumbers are known to enhance immune function by improving the phagocytic ability of the body's monocytes and macrophages and are effective in treating diabetes and asthma.

The nutritional composition of raw sea cucumber is about 91.8 g of moisture, 3.7 g of protein, 0.4 g of fat, 1.3 g of sugar, and 2.8 g of ash per 100 g, and the ash contains 119 mg of calcium, 27 mg of phosphorus, 2.1 mg of iron, and 0.01 mg of vitamin B1. , B2 0.03 mg, niacin 1.2 mg, and taurine 18 mg. When raw sea cucumbers are dried and made into dried sea cucumbers, the moisture per 100 g of dried sea cucumbers is reduced to about 1.5 g, making them almost anhydrous, and various nutrients are concentrated to approximately Protein increases to 77.6 g, fat 0.9 g, sugar 3.0 g, ash 17.0 g, calcium 1.4 mg, phosphorus 72 mg, iron 53 mg, vitamin B1 0.06 mg, B2 0.08 mg, and niacin 4.0 mg.

Sea cucumbers composed of sticky glycoproteins can easily deteriorate during the distribution process through contact with oxygen, so they are generally distributed as dried sea cucumbers. Dried sea cucumbers, which are consumed in large quantities, are manufactured through the process of boiling sea cucumbers, salting them, and then drying them.

However, during this process, a large amount of boiling by-products are generated and most of them are discarded, resulting in significant economic loss and raising environmental pollution issues. In addition, while sea cucumber boiled liquid contains a large amount of functional ingredients such as useful nutrients such as polyphenols, proteins, and glycogen, it also contains substances that cause eutrophication of water quality, such as nitrogen compounds, and is directly or indirectly affected by marine pollution. There is an urgent need to prepare measures for reprocessing or recycling as much as possible. Conventionally, most research on sea cucumbers involves the development of foods using the sea cucumber itself, and research on developing functional products using sea cucumber boiled liquid is very limited.

Meanwhile, salt is a white crystal whose main ingredient is sodium chloride (NaCl). It is an essential food for the human body's vital activities such as transmission of nerve impulses, muscle contraction, absorption and transport of nutrients, and maintenance of blood volume and blood pressure, and is used to flavor food. In particular, it is essential in food processing as it acts as a pickling or natural preservative by expelling moisture from the organism through osmotic pressure. In addition, salt's main ingredient is sodium chloride (NaCl), and it also contains moisture, calcium, magnesium, and potassium, but there are differences depending on the type.

Salt is largely classified into refined salt and sea salt. Refined salt is a crystal of sodium chloride obtained by electrolyzing seawater and removing impurities and heavy metals with an ion resin film. Sea salt is an unprocessed salt made by bringing seawater to a salt farm and evaporating the moisture and harmful ingredients with wind and sunlight. It has thick, translucent, hexagonal crystals.

In the case of refined salt, it can be classified into processed salt such as roasted salt, roasted salt, and bamboo salt that has gone through a heating process, and mass-produced mechanical salt or chemical salt. Mechanical salt or chemical salt is usually manufactured by electrodialysis of seawater through an ion exchange membrane, and even the healthy minerals contained in the salt are removed. Research results have reported that such refined salt has too high a salt content, causing various adult diseases such as hyperlipidemia and arteriosclerosis.

On the other hand, sea salt is a salt made by concentrating seawater by using natural sources such as solar heat and wind to flow seawater into a reservoir. Although the purity of sodium chloride is low at around 80-86%, it contains a large amount of minerals and organic components from the mud flat that are beneficial to our body. It is nutritionally excellent and suitable for making traditional kimchi or making various sauces.

Magnesium contained in sea salt promotes cell metabolism, activates enzymes, and acts on bone metabolism along with calcium and phosphorus. Calcium contained in sea salt strengthens cell membranes and bones and is involved in heart muscle and nerves. Potassium contained in sea salt discharges waste products out of the body through moisture retention, regulates muscle contraction, and induces smooth activity of nerve roots. In particular, domestic sea salt is known to have the effect of alleviating adult diseases such as diabetes and arteriosclerosis.

However, research and product development on sea salt are insufficient worldwide, and the present invention seeks to provide salt using sea cucumber hot water extract, which contains a large amount of functional substances.

<Example 1. Production of sea cucumber hot water extract>

The preparation of the sea cucumber hot water extract of the present invention involves adding water to pretreated sea cucumber and heating it at 90°C for 10 minutes under a pressure of 1.5 kg/cm2 to prepare the sea cucumber hot water extract. The prepared sea cucumber hot water extract is cooled to a temperature of 20°C. Includes process.

(A) Sea cucumber pretreatment step

The sea cucumber pretreatment step (A), in which the internal organs of the sea cucumber are removed, washed, placed on a tray, and salted with sea salt, is a sea cucumber cleaning and preparation process for producing sea cucumber hot water extract. First, cut open the abdomen of the raw sea cucumber and remove the internal organs. During this process, make sure the incision is not too small or too large, and make sure the sea cucumber intestines do not burst when removing the intestines.

After removing the intestines, fresh sea cucumbers are washed thoroughly under running water, placed on a colander, and salted with 0.5% sea salt. The sea salt used at this time is domestically produced salt, and it is desirable to use sea salt that has had the bittern removed for 12 to 36 months to avoid bitterness. Roasted salt or brine can also be used. The salting process is a process of treating prepared sea cucumbers with salt, and is carried out for 8 to 10 hours by adding 5 g of sea salt to 1,000 g of sea cucumbers.

(B) Steps for producing sea cucumber hot water extract

Step (B) of producing sea cucumber hot water extract is a process of placing the sea cucumber pretreated in step (A) with water in a double boiler and heating it at 90°C or higher for 10 minutes to obtain sea cucumber hot water extract and dried sea cucumber process. Sea cucumber hot water extract is prepared by adding 200 parts by weight of water to 100 parts by weight of sea cucumber pretreated through step (A) and heating at 90°C to 100°C for 10 to 30 minutes under a pressure of 1.5 kg/cm2.

The water is preferably 1.5 to 2 times the weight of the sea cucumber. If it is less than this, the salt inside the sea cucumber cannot fully escape. If it is more than this, the salt inside the sea cucumber is sufficiently released, but a lot of moisture remains inside the sea cucumber, which reduces the marketability and preservation of the sea cucumber. There is a risk that this may be hindered.

After the hot water extraction process is completed, the sea cucumber hot water extract is obtained, and the sea cucumber is taken out of the double boiler and dried through salting and boiling to produce dried sea cucumber. Sea cucumber hot water extract obtained from sea cucumbers is used in the salting stage of fish and contains the nutrients such as saponin and amino acids of sea cucumbers.

In the process of manufacturing dried sea cucumbers, most of the large amount of boiling by-products generated after ripening sea cucumbers are generally discarded. In this case, the discarded boiling by-products contain a large amount of useful ingredients such as saponin and amino acids contained in sea cucumbers. . The results of comparing the saponin content contained in sea cucumber hot water extract and ginseng are shown in Table 1.

Saponin content contained in sea cucumber hot water extract and ginseng extract saponin content Sea cucumber hot water extract Ginseng Rg1 0.016mg/g 0.29mg/g Re 0.008mg/g 0.34mg/g Rf 0.005mg/g 0.14mg/g Rg2+Rh1 0.013mg/g - Rb1 0.005mg/g 0.27mg/g Rc 0.021mg/g 0.15mg/g Rb2+Rb3 0.020mg/g 0.11mg/g Rd 0.006mg/g 0.08mg/g Rg3
(S,R) 0.0006mg/g - Rh2 0.0004mg/g -

As shown in Table 1, it can be seen that sea cucumber hot water extract contains saponin components that have been reported to have effects such as Rg1 (immune function enhancement), Rb1 (sedative effect), and Rg3 (anticancer effect). Additionally, it can be seen that sea cucumber hot water extract contains various types of amino acids.
