Description

  The present invention relates to a novel paste raw algae composition and a method for producing the same.

  The taste of paste raw algae (so-called raw paste) has a unique softness and umami, unlike dried plate paste and roasted paste. However, paste raw algae are easily denatured, and the cell contents are eluted in one to three days in either the dehydrated paste, the soaked sea water, or the fresh water soaked, Leaves turn red and have a strange odor. This is the same for low-temperature storage or salting treatment used in wakame, and it becomes unsuitable for food in a short period of time. For this reason, it has been difficult to distribute the paste algae in general.

  So far, various techniques for preserving raw glue have been disclosed. For example, several techniques have been developed to improve the preservability of the seedlings in their seedlings by semi-drying them in the state of young leaves and then freezing them. It cannot be applied from the aspect of Noh.

  On the other hand, in the production of dried glue, as a method for preventing quality degradation of raw raw material, raw glue is an aqueous solution of a water-soluble salt of at least one acid selected from the group consisting of an organic acid and phosphoric acid. A treatment method for cleaning is disclosed (for example, see Patent Document 1). Similarly, in the production of dry paste, in order to prevent the freshness of the plucked raw algae from being reduced, one or more of organic and inorganic acids are added and immersed or sprayed in seawater adjusted to pH 4.0 to 6.5. And a method of storing them is disclosed (for example, see Patent Document 2). However, these methods are merely methods for maintaining the quality for several hours to half a day until the plate paste production, and the quality cannot be maintained for a period sufficient to distribute raw paste as food. .

Moreover, the method of preserve | saving raw paste in acetic acid aqueous solution is disclosed as a technique aiming at distribute | circulating as a foodstuff (for example, refer patent document 3). However, when stored in an acetic acid aqueous solution, reddening of the leaflet body and loss of gloss are still inevitable. In addition, when glue is heated, pigments with low heat resistance (phycoerythrin, phycocyanin) usually fade, and the presence of heat-resistant pigments (chlorophyll, carotenoids) becomes noticeable, resulting in a bright green color. Under storage in acetic acid aqueous solution, this chlorophyll also changes in quality and does not exhibit a green color even when heated, which impairs the commercial value as raw food. As described above, no technology has been developed yet to sufficiently maintain the quality of the raw material and withstand distribution as food.

  An object of the present invention is to provide a novel paste raw algae composition excellent in preservability, which can store paste raw algae for a period sufficient to withstand distribution as a food, and a method for producing the same. . In other words, the cell membrane rupture of paste green algae suppresses the elution of cell contents to the outside of the cell and the progress of decay, maintains the taste, aroma, and texture in a raw state, and pigments (chlorophylls, carotenoids, phycoelis) It is to provide a composition capable of suppressing elution / degeneration of phosphorus, phycocyanin).

  As a result of intensive studies to solve such problems, the present inventors have obtained a salt selected from glue algae belonging to red algae and organic dibasic acid salt or tribasic acid salt or diphosphate salt. A paste raw algae composition comprising (1) 0.5 to 15% by weight of the dry raw algae, (2) 15 to 50% by weight of the salt, and (3) 35 to 85% by weight % Of water and a pH in the range of 6-9 was found.

  The paste raw algae composition of the present invention, for a long period of time, the cell content of the paste green algae ruptures the cell content components to the outside and the progression of decay is suppressed, and pigments (chlorophyll, carotenoids, phycoerythrin, The phycocyanin) is prevented from being altered / dissolved and has excellent storage stability. Therefore, glue algae (raw paste) preserved in such a composition maintain the taste, aroma and texture in a raw state, and exhibit a unique vivid green color when heated. It is suitable for distribution as food without loss.

  The present invention is a paste algae composition comprising a paste algae belonging to red algae and a salt selected from an organic dibasic acid salt, a tribasic acid salt, or a secondary phosphate, (1) in terms of dry weight 0.5 to 15% by weight of the green seaweed, (2) 15 to 50% by weight of the salt, and (3) 35 to 85% by weight of water, and the pH is in the range of 6 to 9. It relates to a composition characterized by being. The present invention is also characterized in that a salt selected from an organic dibasic acid salt, a tribasic acid salt, or a diphosphate salt is added to and mixed with a raw algae belonging to red algae. It also relates to a method for producing an algal composition.

  The “paste algae belonging to red algae” used in the composition of the present invention means a seaweed used as a raw material for foods so-called “paste”. Specifically, “Principal algae belonging to red algae” refers to seaweed that belongs to the red algae plant gate and is named “Nori” in taxonomic terms. Preferably, it belongs to (Porphyra). Examples thereof include those of the genus Amanori such as Asakusa Nori, Susabi Nori, Kosuginori, Maruba Amanori, Tsukusia Manori, Cronori, Uppuinori, Chishimacrinori, Proboscis, Tosakanori and the like.

  The composition of the present invention contains 0.5 to 15% by weight, preferably 1 to 10% by weight, particularly preferably 2 to 10% by weight, of such paste algae in terms of dry weight. Paste seaweed (raw seaweed) is usually cut from seaweed collected to a desired size with a chopper, etc., and then washed with water, artificial seawater, filtered seawater, etc. Although it means what has been dehydrated as appropriate, in general, dehydrated paste algae (raw paste) occupy about 80 to 99% by weight, more preferably 85 to 98% by weight of its weight. That is, the “paste algae” (raw paste) of the present invention also contains about 80 to 99% by weight, more preferably 85 to 98% by weight, of its weight. Therefore, "dry weight conversion" corresponds to the weight when the paste raw algae is dehydrated and further subjected to a drying step and dried, and in the present invention, from the weight of "paste raw algae (raw paste)" It shall be synonymous with the value except the moisture content.

  On the other hand, a salt selected from organic dibasic acid salt or tribasic acid salt or dibasic acid salt used in the composition of the present invention is allowed to be used in food as a food additive and the like. When present at 15-50% by weight, preferably 20-40% by weight, the pH is neutral to weakly alkaline, i.e., the pH is in the range of about 6-9, preferably in the range of 6.5-8.5. If it is in.

The “organic dibasic acid salt or tribasic acid salt” of the present invention means a salt of an organic acid having 2 or 3 carboxyl groups in the molecule, specifically, malic acid or citric acid. Alkali metal, alkaline earth metal or ammonium salt of tartaric acid or succinic acid, or hydrates thereof. The “secondary phosphate” of the present invention means a phosphate represented by the formula: M ₂ HPO ₄ (where M is an alkali metal, alkaline earth metal or ammonium salt), and specifically Specifically, disodium hydrogen phosphate or diammonium phosphate, or a hydrate thereof may be mentioned.

  Preferred “salts selected from organic dibasic acid salts or tribasic acid salts or dibasic phosphates” are disodium malate, trisodium or tripotassium citrate, disodium tartrate, diammonium hydrogen phosphate or the like. Hydrates such as disodium malate trihydrate, trisodium citrate dihydrate, tripotassium citrate monohydrate, disodium tartrate dihydrate, particularly preferred Is disodium malate or its hydrate, for example disodium malate trihydrate. You may mix | blend these with the composition of this invention individually or in mixture of 2 or more types. In addition, when the said salt is a hydrate, the weight converted into the corresponding anhydride is considered.

  When the concentration of the salt is less than 15% by weight, suppression of elution of cell content components, particularly water-soluble pigments, outside the cells is at a level that is satisfactory from the viewpoint of long-term storage of paste algae as an object of the present invention. Since it is not, it is not preferable. For this purpose, the concentration of the organic acid salt in the aqueous solution is suitably about 15% by weight or more, preferably about 20% by weight or more, particularly about 25% by weight or more. Is preferred. The upper limit is not particularly limited from the viewpoint of the effect of the present invention, but it is about 50% by weight from the viewpoint of avoiding the water solubility of the salt, the cost, and the bulkiness when considering the distribution as a composition. % Or less is suitable, and desirably it is about 40% by weight or less.

  The composition of the present invention can be produced by adding the salt to the paste algae and mixing them. However, any method can be used as long as the two can be mixed and contacted effectively. There may be. For example, the collected seaweed is washed with water, artificial seawater, filtered seawater, etc., drained lightly, and the salt is added to this so as to have a concentration of 15% by weight or more. The salt may be uniformly dissolved in water contained in the algae. Further, the collected seaweed may be washed and dehydrated in the same manner, and an aqueous solution containing the salt may be sprayed on the seaweed, or the dehydrated one may be immersed in the aqueous solution containing the salt.

  In addition, the paste raw algal composition of the present invention may be stored at a normal food storage temperature, for example, a temperature in the range of -5 to 30 ° C, but in a range of 0 to 10 ° C, particularly 4 ° C. Is more preferable. The paste raw algae composition of the present invention includes those packaged as a food form. As a packaging mode, a known packaging may be used, but among these, a sealed packaging type such as bottled packaging, canning, vacuum packaging or the like is preferable.

  In the composition of the present invention and the production method thereof, as described above, artificial seawater or filtered seawater may be used in addition to water. Therefore, when the latter artificial seawater or the like is used, the composition of the present invention inevitably contains a mineral component contained in the artificial seawater in addition to the paste algae and the salt. Furthermore, if desired, the composition of the present invention may contain additives commonly used in foods. Examples thereof include sugar, amino acids, vegetable oils and fats, fish meat extract, livestock meat extract, vegetable extract, and fermented seasoning.

  Hereinafter, although a specific aspect is shown as an example of the present invention, the present invention is not limited to these. In the following examples, “%” means “% by weight” unless otherwise specified.

  The water content of paste raw algae was measured using a heat drying moisture meter MX-50 (manufactured by A & D Co., Ltd.).

[Test Example 1]
Washed with artificial seawater (Marine Art Super Formula, manufactured by Tomita Pharmaceutical), dehydrated by lightly draining with a colander, 50 g each of green algae (Susavinori; moisture content 90%), 3 cups of vinegar ^{* 1} 100 g (No. 1) ), Black vinegar diluted solution ^{* 2} 100 g (No. 2), salt 25 g (No. 3), artificial seawater 100 g (same as above; No. 4) and DL-malic acid disodium trihydrate (No. 5) ) And mixed, and stored at 4 ° C. for 4 weeks. The sample was evaluated for the pH at the time of preparation of each sample (day 0) and for each item after 8, 15 and 28 days. The results are shown in Table 1 below.

  In the observation on the 8th day, the ones added with three cups of vinegar and black vinegar (No. 1 and 2) caused discoloration of the original algae leaves and apparently looked different from fresh original algae. This is thought to be because chlorophyll, which is one of the pigments contained in glue, changed to pheophytin in the acidic region and changed from green to brown. Moreover, in addition to the discoloration of the leaf body, the elution of the pigment was observed in the sample added with salt (No. 3). In the artificial seawater only (No. 4), the pigment was eluted out of the cell, and the original algae turned red and gave off a strange odor. On the other hand, in the case of adding disodium malate trihydrate (No. 5), even after 4 weeks, discoloration of the leaf body, nasty smell, and elution of the pigment were not confirmed, and the good state was maintained. Regarding the number of viable bacteria, no growth was observed in any of the test sections from the time of preparation of each sample (day 0) to the end of the test (after 28 days).

[Test Example 2]
In the same manner as in Test Example 1, after washing and draining, 100 g of each of the green algae (Subinori; water content 95%) was added with disodium malate trihydrate at various concentrations, and 4 weeks at 4 ° C. saved. Table 2 below shows the sample evaluation results for each item after 7, 15 and 28 days, together with the amount of malate added (g, weight%) and the pH at the start of the test (0 days). No. 1 (no malate added) and No. 1 11 (addition of malate), a portion of the original algae after 15 days have been collected and the results of microscopic observation thereof are shown in FIGS.

  In the observation on the 7th day, in the test group (No. 1) in which no salt was added, the leaf body was discolored and the gloss was lost, and elution of the pigment and generation of a strange odor were observed. The test group (Nos. 2 to 4) in which the amount of malate added was 1% by weight or less was almost the same as the test group without addition. Further, even in the test section (No. 5 and 6) in which the amount of malate added was 1 to 10% by weight, elution of the dye was observed in the observation on the seventh day. On the other hand, in the test section (No. 8 to 11) where the amount of malate added exceeds 15% by weight, no discoloration of the leaf body, no foul odor, and no elution of the pigment were confirmed after 2 weeks, and the good condition was maintained. Was. Furthermore, in the test section (Nos. 8 to 11) in which the amount of malate added exceeds 20% by weight, a good state was maintained even after 4 weeks. Regarding the number of viable bacteria, no growth was observed in any of the test sections from the time of preparation of each sample (day 0) to the end of the test (after 28 days).

  1 and 2, the cells of the original algae stored without malate were clearly eluted and shrunken, whereas the original algae stored in the presence of a high concentration of sodium malate. It is clear that the contents of these cells are retained with little change compared to the original cells.

[Examples 1 to 5, Comparative Examples 1 to 4]
In the same manner as in Test Example 1 above, it was washed and dehydrated by lightly draining water with a colander. ), Trisodium citrate dihydrate 50 g (Example 2), disodium tartrate dihydrate 50 g (Example 3), tripotassium citrate monohydrate 50 g (Example 4), dihydrogen phosphate Ammonium 50 g (Example 5) was added thereto and stored at 4 ° C. for 4 weeks. On the other hand, as a comparative example, 100 g of each of the above original algae, 100 g of sodium lactate (50% solution), (Comparative Example 1), 50 g of sodium acetate (Comparative Example 2), 50 g of monosodium phosphate dihydrate (Comparative Example 3) And trisodium phosphate dodecahydrate (Comparative Example 4) were added, respectively, and similarly stored at 4 ° C. for 4 weeks. Table 3 below shows the pH at the time of preparation of each sample (day 0) and the evaluation results for each item after 7, 15 and 28 days.

  In the observation on the 7th day, the elution of the dye was slightly observed in the samples to which sodium lactate (Comparative Example 1) and sodium acetate (Comparative Example 2) were added, and this increased as the number of days passed. On the other hand, the acid-added monosodium phosphate (Comparative Example 3) had no noticeable change in the observation on the 7th day, but the color of the leaf body was slightly in the observation on the 15th day. In addition to being reddish, pigment elution was also observed. In the case of adding alkali sodium trisodium phosphate (Comparative Example 4), the leaves became bright green and the leachate turned brown in the observation on the seventh day. On the other hand, sodium malate, trisodium or tricitrate citrate, disodium tartrate, and diammonium hydrogen phosphate (Examples 1 to 5) were changed in leaf color, odor, and pigment after 4 weeks. No elution was confirmed, and a good state was maintained. Regarding the number of general viable bacteria, no growth was observed in any of the examples from the time of preparation of each sample (day 0) to the end of the test (after 28 days).
