Flaxseed Detoxification and Steaming Method {Method for detoxing and steaming flaxseeds}

The present invention relates to a method for eliminating and steaming flaxseed, and more particularly, using a natural germination process to remove toxic substances present in natural flaxseed, and including a steaming process for enhancing edibleness and preservation and enhancing nutrients. To flaxseed poisoning.

Flax is a linaceae plant native to the highlands of Central Asia and is known as Linumusitatissmum. L is. As a low-temperature plant, it is a short-term plant that can be harvested 100 days after planting. It grows in a cold region at 55 degrees north latitude. The seed flaxseed is an annual nut seed, and its stem is 70-100 cm, but the root is 3 m. Because of the growing conditions that require a substance, it is not grown for 7 years once grown. This is equivalent to roots deeply rooted to survive in harsh environments. Growing flaxseeds, which grow with strong self-support, are edible and medicinal, vegetable omega-3, dietary fiber, and lignin tocopherols. Numerous essential ingredients, including folic acid and minerals, are concentrated and contain about 24% of dietary fiber.

Ungerminated flaxseed contains a number of nutrient absorption inhibitors and toxicity that the body does not want, and if the seeds are ingested as they are, the actual nutrient absorption may be low and they may be exposed to toxicity. This is the result of the seeds evolving to reproduce and protect their vitality from natural enemies and the environment, which are not digested when eaten by animals or humans.

For this reason, flaxseed contains nutrient absorption inhibitors such as inhibitors that interfere with protein digestion and phytic acid, which absorbs minerals such as calcium, magnesium, iron, copper and zinc. The absorption of nutrients is so marked that there is little nutritional benefit. It also contains a cyanide, a toxic component, which can be toxic to flaxseed when consumed in large quantities.

Germination of flax seeds undergoes self-extinguishing. Self-extinguishing acts to remove unnecessary cellular components in the process of cell reconstruction, and to remove toxic substances and nutrient absorption inhibitory elements required to protect seeds from natural enemies during the process.

In addition, when seeds germinate, the activity of enzymes that catalyze the absorption of nutrients is increased and nutrient absorption inhibitory elements are reduced.

Nutrient absorption inhibitors, such as phytic acid, are found in large amounts in seeds. There are two ways to reduce this: heat treatment at high temperature and germination.

The method of heat treatment at a high temperature is more useful to germination because the useful nutrients are also destroyed. In other words, germinated flaxseed is enhanced in plant protein, essential fatty acids, antioxidants, nutrients such as vitamins and minerals, nutrient absorption inhibitors are reduced, and enzyme activity better for nutrient absorption is increased. Improves naturally.

 Cyanide, a toxic substance in flaxseed, also self-digests during germination and naturally decreases. (Reference: Jaehee Lee, Kyongshin Cho ,; Flaxseed sprouts induce apoptosis and inhibit growth in MCF-7 and MDA-MB-231 human breast cancer cells)

However, it is difficult to germinate flaxseed and process it into food due to the following factors.

First, the outer shells of the double seed shells that make up the shell of flaxseed are mucus pieces that secrete pectin-like substances upon contact with moisture. This substance protects seeds from passing through the digestive tract rather than digesting them when animals eat them. When a person consumes flaxseed raw, the mucus is also released without digestion. The mucus secreted by flaxseed is a complex molecular sieve with a very complex composition, and its composition is still partially identified.

Flaxseed, which is protected by mucus, can be germinated on several kinds of carrier materials (soil, cotton, burlap, etc.) but is not suitable for mass production, and flaxseed without mucus is suppressed and germinated for germination. Prevent sterilization. Therefore, this mucus must be removed to obtain flaxseed germination.

Alzueta R. reported that when milled flaxseed (including mucus) was added to chicken food, the mucosa interfered with digestion and reduced the size of the chicken, despite the very high nutritional value of flaxseed (Br. Poult. Sci. 44 (10: 67-74, 2003)

Mucus is known to have a gel structure and is stabilized by crosslinking and thus cannot be removed by general washing, pressing or stirring. Some commercial manufacturing processes are treated with acid and high temperature (80 ° C.), in which case the seed loses its vitality and thus the germination targets of the present invention cannot be obtained.

Secondly, the flaxseed oil content is 40-60%, of which more than 70% are unsaturated fatty acids. As a result, it reacts very quickly with oxygen in the air and causes rancidity.

In order to ferment, generally, a process of ripening for a long time in a gentle state above room temperature. Under these fermentation conditions, the oil of flaxseed can easily be rancid, so the oil must be treated before fermentation.

 According to Korean Patent Laid-Open Publication No. 10-2008-0113191, (iii) an aqueous enzyme solution containing at least one pectinolytic enzyme, a cellulolytic enzyme and optionally a proteolytic enzyme. Processing flaxseed; (Ii) removing the mucus material isolated from the surface of flaxseed during step (iii); (Iii) washing flaxseed obtained in this manner for slime removal; (Iii) sterilizing the flaxseed obtained in step (iii); And (iii) germinating the sterilized flaxseed, a method for producing a demuxed flax germ is disclosed. The patent discloses a method of removing mucose of flaxseed by treating flaxseed in a mucolytic solution to which various enzymes are added.

However, the method is according to the purpose of separating the mucosa separately for use in edible to medicinal, there is a problem in that unnecessary costs are involved in preparing and operating the enzyme solution when removing the mucosa and obtaining only flax seed germination.

In order to solve the conventional problems as described above, the present invention provides a method for eliminating flaxseed toxicity and steaming by removing the mucosa of flaxseed without chemistry, cultivating and steaming flaxseed germination to enhance nutritional ingredients and increase the preservation do.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but is to be understood to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention, And the scope of the present invention is not limited to the following examples.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like or corresponding elements are denoted by the same reference numerals, and redundant explanations thereof will be omitted.

1 is a flow chart illustrating a flaxseed toxicity removal and steaming method according to an embodiment of the present invention.

Referring to Figure 1, flaxseed toxicity and steaming method according to an embodiment of the present invention, washing and water supply step (S10), mucus removal step (S20), germination induction step (S30) and steaming and drying step ( S40).

Washing and hydrating step (S10) is a step of supplying the necessary water for washing the foreign matter and the mucus discharge of flaxseed by repeating the immersion treatment of flaxseed, stirring and removing the water. The washing and water supply step S10 may further include four detailed steps. Washing and hydration The first step (S11) is a step of immersing the flaxseed in washing water between 15 ~ 20 ℃ and stirred for 4 to 6 minutes to remove the washing water. The second step of washing and supplying water (S12) is a step of removing the washing water after stirring for 2 to 4 minutes in the washing water of the same temperature. The third step (S13) of washing and supplying water is a step of removing the washing water after stirring the washing water for the same temperature again for 2 to 4 minutes. The fourth step (S14) of washing and supplying water is a step of removing the washing water after stirring for 0.5 to 1 minute in the washing water of the same temperature. During this several stages of washing, the flaxseed absorbs moisture to form a mucus layer, and impurities such as dust or dirt may be removed between the flaxseeds. In the above process, a mesh net or a gardening net may be used to separate the washed water and flaxseed after the washing is completed.

The mucus removal step (S20) is carried out in a state in which the mucous is sufficiently discharged by the flaxseed after the above step contains 70 to 100% of water by weight. The mucus formed flaxseed is placed in a centrifuge and treated to allow the mucus to be separated from the flaxseed. At this time, it will be preferable to put the flaxseed in a mesh net and put in a centrifuge so that the mucus is separated from the flaxseed and discharged. In the slime removal step (S20), the slime is removed so that the weight of the slime is 5-20% of the total sample weight.

Germination induction step (S30) is the first step of germination induction (S31) to stabilize for 30 to 90 minutes after the mucus is removed and the moisturized flaxseed in the germination container and stirred so that oxygen can be supplied sufficiently between the flax seeds ), A second step (S32) of inducing germination to stir the stabilized flaxseed again to supply oxygen and stabilizing for 120 to 240 minutes, and supplying oxygen to stir the stabilized flaxseed again to stabilize the germination inducing agent. It includes three steps (S33). In order for the flaxseed to germinate, it is necessary not only to supply oxygen through stirring but also to keep the flaxseed in motion. Therefore, after stirring, it is desirable to put a stabilizer so that the germination process proceeds in a stable state without moving the flaxseed. The flaxseed is not dried and is required for germination only when the flaxseed is maintained to contain 40 to 60% of water by weight by maintaining a humidity of 70 to 80% and a room temperature of 25 to 30 ° C in the three steps. Can be maintained.

When the flaxseed is germinated through the above steps, the toxic substances in the flaxseed are removed during the self-extinguishing process.

Steaming and drying step (S40), the first step (S41) steaming and drying the germinated flaxseed at low temperature so that the temperature is lowered to 50 ~ 70 ℃ continuously for 3 to 5 hours starting at a temperature of 70 ~ 90 ℃ ), The second step (S42) of steaming and drying to dry for 10 to 14 hours at a temperature of 45 ~ 50 ℃ to dry the water content relative to its own weight to 0.1 to 1%. The low temperature steaming and drying as described above can prevent the deterioration of nutritional ingredients contained in flaxseed and provide germinated flax seed in an edible state. Heating at high temperatures oxidizes the unsaturated fatty acids abundantly contained in flaxseed and destroys vitamins, thus degrading shelf life and palatability and reducing nutritional value.

In accordance with the flaxseed toxicity and steaming method according to the invention Example 1 was carried out as follows.

In the washing and moisturizing step (S10), the first step of washing and moisturizing the soaked flaxseed in 17 ° C wash water and stirring for 5 minutes to remove the wash water; Immersing the flaxseed again in wash water at 17 ° C., stirring for 3 minutes, and then washing and hydrating a second step (S12) to remove the wash water; Immersing the flaxseed again in wash water at 17 ° C., stirring for 3 minutes, and then washing and hydrating a third step (S13) to remove the wash water; Finally, the linseed was again immersed in 17 ° C wash water and stirred for 1 minute, and then washed and hydrated to remove the wash water (S14) to obtain a linseed layer formed with a mucus layer.

In the mucus removal step (S20), the flaxseed was centrifuged in a state containing 83% of water by weight, and the mucus was removed such that the weight of the mucus was 18% of the total sample weight.

In the germination induction step (S30) is the first step (S31) for inducing germination and stabilizing for 90 minutes after the mucus is removed and the moisturized flaxseed is placed in the germination container and oxygen is supplied between the flax seeds; A second step (S32) of inducing germination to stir the stabilized flaxseed again to supply oxygen and to stabilize for 240 minutes; The stabilized flaxseed was stirred again to supply oxygen, and the flaxseed was germinated through a third germination-inducing step (S33) of stabilization until germination.

At this time, the humidity of 78%, the room temperature of 27 ℃ was maintained in the three steps, the water content of the flaxseed relative to its own weight was 57%.

In the steaming and drying step (S40), starting at a temperature of 80 ° C, steaming and drying at a low temperature so as to linearly lower the steam temperature to 45 ° C for 4 hours, and then drying at 45 ° C for 12 hours through the first step (S41). Steaming and drying The germinated and dried germinated seedlings were obtained through a second step. The moisture content of the flaxseed relative to its own weight was 0.5%.
