Description

  The present invention relates to a pulverization technique for whole flaxseed seeds, and is particularly effective when applied to suppress stickiness of pulverized linseed seeds due to oils and fats generated during the pulverization of flaxseed seeds.

  Plant seeds contain substances beneficial to health, and many health foods and the like containing such seeds are sold. For example, various seeds such as sesame seeds, wheat germ, almonds and sunflowers, as well as the oils and fats such as linoleic acid extracted from them are sold as products.

  Oils and fats contained in such seeds exist as fatty acids and are classified in terms of molecular structure as omega-3, omega-6, etc., depending on the position of unsaturated carbon from the terminal methyl group. Examples of omega-3 include α-linolenic acid. Omega-6 includes, for example, linoleic acid. Thus, oils and fats such as omega-3 contained in seeds are useful as essential fatty acids, are not produced in the body, and it is said that it is necessary for health to be taken in appropriately from the outside, for example, by ingestion.

  On the other hand, in recent years, it has been found that not only oil and fat components such as fatty acids but also seed coats constituting seeds are useful as proteins, minerals, and dietary fibers, and it is necessary to ingest the whole seeds with good digestibility. The recognition is expanding.

  However, even if it is intended to ingest the seed itself, the seed coat is generally hard and difficult to digest, so an attempt has been made to make it easy to ingest and digest easily by pulverizing. For example, Patent Document 1 proposes a technique for pulverizing hard seed coats of sesame seeds so that they can be easily ingested.

  In the technique proposed in Patent Document 1, sesame seeds are once steamed and softened, and then sesame seeds are squeezed to remove oil and fat to some extent. A technique is disclosed in which the squeezed residue whose oil content is adjusted to a predetermined amount is frozen in a liquid nitrogen atmosphere and further pulverized.

  In such a proposed technique, a predetermined amount of oil and fat is squeezed and removed, and then the squeezed residue is frozen and pulverized. It is said that sesame powder is obtained. In particular, since sesame powder has a certain amount of oil and fat, it also has a sesame flavor and is described as being a process that is easy to ingest, unlike simple squeezing.

As for wheat flour, whole grain flour is already on the market, and it is used in various products made from wheat flour such as bread and spaketty, and has been well received in response to the recent health food boom.

  The inventor has also paid attention to the fact that flaxseed seeds have an essential fatty acid content that surpasses that of sesame seeds, and is extremely health-friendly. I have been researching. In particular, research has been conducted on whether it is possible to produce flaxseed seed whole grains.

  However, linseed seeds are used as a raw material for linseed oil and contain a large amount of oil and fat. Therefore, even if pulverized by a pulverizer or the like, the pulverized powder becomes sticky due to the oil and fat generated during the pulverization, and a crushed powder with no stickiness is not obtained. The stickiness may be, for example, an image of stickiness of raw sesame or roasted sesame in a mortar.

  As disclosed in Patent Document 1, if flaxseed seeds are squeezed once and the oil content is adjusted to such an extent that stickiness does not occur, so-called flaxseed seeds are ground without stickiness. It is considered possible to produce powder.

  However, the present inventor considered that in order to fully enjoy the effectiveness of the oil and fat component of the linseed seed, it is preferable to grind the oil and fat component contained in the linseed seed as it is. The fat and oil contained in flaxseed seeds is pulverized as it is without adjusting the fat and oil components in advance to the extent that stickiness of the pulverized powder does not occur, and without adjusting the fat and oil content of the flaxseed seeds themselves. Of course, it was considered preferable to use a non-sticky whole grain powder that can totally take in lignum contained in the seed coat.

  Although the technique described in Patent Document 1 is certainly excellent, in the case of applying such a technique, it is necessary to remove and adjust the oil and fat content of flaxseed seeds to some extent. Not applicable to the production of flaxseed seed whole grain flour.

  An object of the present invention is to provide a flaxseed seed whole grain which is not sticky.

  The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

  Of the inventions disclosed in the present application, the outline of typical ones will be briefly described as follows.

  The present invention is a method for producing whole flaxseed seed powder by pulverizing the whole flaxseed seed grain, a freeze-drying step of freeze-drying the whole flaxseed seed grain, and the freeze-dried flaxseed seed And a pulverizing step of pulverizing the whole flocculated seed in the presence of a stickiness inhibitor that suppresses the stickiness of the linseed seed pulverized powder due to the oil and fat generated during pulverization of the whole linseed seed.

  In the method for producing whole flaxseed seeds, the stickiness-inhibiting material is a substance that adsorbs or includes the oil and fat. In the method for producing the flaxseed seed whole grain powder, the stickiness-suppressing material is porous starch.

  The flaxseed seed whole grain powder according to the present invention is characterized by containing a stickiness-inhibiting material that retains oils and fats produced during the pulverization of flaxseed seeds. In this configuration, the flaxseed seed whole grain powder is a pulverized powder that passes through a 16-mesh mesh screen.

  Among the inventions disclosed in the present application, effects obtained by typical ones will be briefly described as follows.

  According to the present invention, it is possible to provide a flaxseed seed whole grain powder that is smooth. Since the flaxseed seed whole grain is smooth, it is easy to ensure the uniformity of the blending when it is mixed with other dry blended components, unlike when it is sticky.

  Further, since the linseed seed pulverized product produced according to the present invention is a linseed seed whole grain powder, different from the pulverized linseed oil pomace of linseed seed, the fat and oil contained in the whole linseed seed is used as a seed coat component. Etc. can be taken in total together.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a flowchart showing the procedure of the method for producing flaxseed seed whole grain according to the present invention.

  As shown in FIG. 1, first, flaxseed seeds to be pulverized are prepared. As the linseed seed used in the method for producing whole grain linseed seed of the present invention, linseed seed already known as a raw material for pressing linseed oil can be used. For example, flaxseed seeds having an average content of linseed oil of 60 to 80% and high oil and fat content that cannot be obtained as it is can be used. Flaxseed seeds are the seeds of flaxseed (scientific name: Linum usitatissimum L.), and the English name for flaxseed is also called linseed or flux.

  For example, commercially available linseed seeds are purchased and washed with a predetermined amount of water or the like. After washing, it may be roasted in an iron pan or the like for sterilization purposes and roasted as necessary.

  The flaxseed seed prepared in this way is freeze-dried in step S100 as shown in FIG. Flaxseed seeds freeze as a whole. In this state, the pressure is reduced to a state close to vacuum, and drying is performed while supplying latent heat that promotes sublimation of the frozen moisture in the frozen flaxseed seeds. By freeze-drying in this manner, the component composition contained in the flaxseed seed grains can be dried while maintaining as much as possible.

  Thereafter, in step S200, the freeze-dried flaxseed seed is pulverized. Even if the linseed seeds are pulverized as they are in the freeze-dried state, the linseed seed pulverized powder becomes sticky due to the oil and fat content from the linseed seeds generated during the pulverization. Sticky lumps and the like are formed, and usually a smooth state imaged as a powder cannot be obtained.

  In the present invention, for the purpose of suppressing stickiness due to oils and fats at the time of pulverization, a stickiness inhibitor is mixed, and lyophilized flaxseed seeds are crushed in the presence of the stickiness inhibitor. The stickiness-inhibiting material plays a role in suppressing the stickiness of pulverized powder such as flaxseed seed seeds mixed with fats and oils by adsorbing or including the fats and oils produced when freeze-dried flaxseed seeds are crushed. .

  As a stickiness-inhibiting material, if a person takes in pulverized linseed seed powder, naturally, a substance that is safe for human consumption must be used. However, if such flaxseed seed grind is applied to animals such as cats, dogs, cows, pigs, chickens, and other non-human pets, livestock, poultry, etc., select those that are safe for consumption in those animals. And use it. Furthermore, when the ground flaxseed seed powder is used for purposes other than the ingestion purpose of animals including humans, it is of course unnecessary to consider such ingestion safety.

  As the stickiness-inhibiting material, any substance that can play the above-mentioned role can be used. More specifically, for example, processed starch, further starch such as porous starch and dextrin, or silicon dioxide series A powder substance capable of adsorbing oils and fats can be used.

  In pulverization, the pulverizer may be pulverized in a state where a predetermined amount of lyophilized flaxseed seeds and the stickiness-inhibiting material are charged. Of course, the whole freeze-dried flaxseed seed and the stickiness-inhibiting material may be preliminarily mixed at a predetermined ratio, and the mixture may be charged into a pulverizer.

  In short, the fats and oils generated during the pulverization of flaxseed seeds are mixed with solid pulverized powder such as the seed coat of flaxseed seeds so that stickiness does not occur and the fats and oils are adsorbed and retained. A stickiness inhibitor may be added. In some cases, the stickiness inhibitor may be added while pulverizing the whole flaxseed seed grains.

  By crushing the whole lyophilized flaxseed seed in the presence of the stickiness-inhibiting material in this way, pulverized powder passing through a 16-mesh mesh screen can be formed.

  In this example, the method for producing flaxseed seed whole grain according to the present invention described in the above embodiment will be described in more detail with specific examples.

In this example, 1 kg of flaxseed seed roasted at about 80-100 ° C. after washing with water was prepared, and the flaxseed seed was freeze-dried as shown in step S100 shown in FIG. In freeze-drying, first, the whole flaxseed seed was frozen at a temperature of −40 ° C., for example. The freeze-dried flaxseed seeds were dried at a temperature below 40 ° C. under a reduced pressure of about 1 Torr (1.33322 × 10 ² Pa) or near vacuum.

  The freeze-dried linseed seeds thus obtained were finely pulverized by adding a porous starch as a stickiness-suppressing material and adding it to a pulverizer as shown in step S200 of FIG. The addition amount as the stickiness-suppressing material may be appropriately set according to the type of the stickiness-suppressing material, based on the adsorption ability of the oil and fat content of the stickiness-suppressing material.

  For example, when a porous starch having an oil / fat adsorption capacity of 50% is used, it may be added at a rate of 500 g with respect to 1 kg of the linseed seeds of the whole lyophilized granule. The pulverized linseed seed powder obtained is a fine powder in which porous starch and linseed seed pulverized components are mixed.

  The linseed seed pulverized powder thus produced contains solid starch such as flaxseed seed seed coat due to the porous starch as a stickiness-suppressing material contained, so that the oil and fat such as linseed oil produced during the pulverization of linseed seeds The phenomenon of stickiness when mixed with powder is suppressed, resulting in a smooth crushed powder.

  In addition, the ground powder of linseed seeds produced in the above manner is different from the case of pulverizing the pomace seeds from which linseed oil has been squeezed once from the linseed seeds. It has become a whole grain.

  According to the analysis of the Food Analysis Center, the content of fats and oils contained in the pulverized powder produced by pulverizing the pomace oil (residue) obtained by squeezing linseed oil from the linseed seed is 5% or less dry For example, linoleic acid was 1.87 g and α-linolenic acid was 3.00 g per 100 g of pulverized powder (powdered powder).

  However, the oil and fat content in the flaxseed seed whole grain produced by the production method according to the present invention described above is based on 100 g of flaxseed seed whole grain powder (containing 30% porous starch) having a moisture content of 5% or less, For example, linoleic acid was 3.38 g and α-linolenic acid was 13.40 g. Considering that the whole grain powder contains porous starch, it can be seen that the flaxseed seed whole grain powder produced according to the present invention contains a large amount of fat and oil.

  The porous starch used in the above production method is a modified starch commonly called “perforated starch”, which is a starch processed using an enzyme change or drum drying method. In addition to the porous starch, for example, cyclodextrin may be used. Furthermore, as described above, in addition to starch, for example, a substance capable of adsorbing silicon dioxide-based fats and oils can be used as a stickiness-inhibiting material in the same manner as the porous starch.

  As the pulverizer, a commonly used pulverizer can be used. For example, a pulverizer such as a power mill or a hammer mill may be used. The linseed seed pulverized powder pulverized by such a pulverizer can be adjusted in the particle size range of the linseed seed pulverized powder by passing it through a mesh screen of a predetermined mesh.

  The maximum particle size of the flaxseed seed whole grain produced by the above method is preferably set in the range of 1 mm to 2 mm.

Although it is possible to set the maximum particle size to less than 1 mm, it has been experimentally confirmed that the yield is actually very poor. That is, the flaxseed seed pulverized powder having a maximum particle size of less than 1 mm is provided with a mesh having a mesh of 1φ (1 mm) or less around the grinder so that the crushed flaxseed seed pulverized powder passes through the mesh applied by centrifugal force. Can be sized and manufactured.
When a mesh of φ mesh is used, pulverized powder larger than the mesh diameter collides, and the oil and fat that had been incorporated in the stickiness-suppressing material oozes out at the time of the collision. It was confirmed that the yield of the pulverized powder was extremely deteriorated. From the viewpoint of production yield, the mesh used is preferably 1φ or more, and the maximum particle size of the flaxseed seed whole grain powder is preferably set to 1 mm or more.

  In addition, a large pulverized powder having a maximum particle size exceeding 2 mm is difficult to use when encapsulating a required amount in a capsule or the like when mixed in a health food or the like.

  Therefore, in the present invention, it was judged that the maximum particle size of the flaxseed seed whole grain powder is preferably 1 mm or more and 2 mm or less.

  In addition, the method for producing flaxseed seed whole grain powder according to the present invention is an effective technique for producing a crushed powder made of flaxseed with a large amount of oil and fat. Naturally, it can be applied by adjusting the amount of the material added. Furthermore, it can also be applied to freeze-drying pulverized linseed oil.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment. However, the present invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the invention. Needless to say.

  That is, the stickiness-suppressing material to be used may be used even when only one type is used, or a plurality of types of stickiness-suppressing materials may be blended and used.

  In addition to the whole grain of flaxseed seeds, the whole grain may be produced by blending whole grains of other seeds.

  The present invention can be effectively used in the field of flaxseed seed grinding.

It is a flowchart which shows the procedure of one Embodiment in the manufacturing method of the flaxseed seed whole grain which concerns on this invention.
