Description

  The present invention relates to a processed food using peaches and a method for producing the same.

  In raw peaches, the appropriate number of results is adjusted by picking to harvest as much high-quality fruit as possible. The fruit picked by this fruit picking may be discarded as it is, but it may be processed into processed foods such as honey boiled or syrup boiled. In the case of peach fruit before the hard nucleus period, it is the stage before the endocarp nucleus hardens and becomes seeds, and the endocarp is not so hard, so it is possible to eat the entire endocarp including the nucleus is there. For example, in the case of boiled syrup, it is processed so that the whole fruit can be eaten by simmering until the endocarp becomes soft while adding a small amount of sugar solution to the picked fruit in small portions.

  However, when it is simmered over time in this way, there is a problem that it takes time to manufacture and is not efficient. In addition, when the inner fruit skin is boiled until it becomes soft, the mesodermal skin becomes too soft, and there is a problem that the flesh of the pulp tends to collapse, and the hardness of the whole fruit cannot be adjusted. Furthermore, if the cooking time is not sufficient, the endocarp skin is not sufficiently soft, the texture is poor, and the taste does not soak. As described above, the factor that the inner skin is hard and the seasoning is difficult to penetrate is due to the lignin and hemicell sauce contained in the inner skin. In particular, in the endocarp, lignin and the like are present between the cell secondary wall and the cell wall layer that form the outside of the cell lumen, and function as a cell-cell adhesion substance and a skeletal structure reinforcement substance. It plays the role of outer shell formation and hardening of the nucleus (seed) after the season. Before the hard nucleus period, lignin and the like are gradually accumulated in the cell tissue of the endocarp, and the endocarp is not clearly hardened, but the cell tissue of the endocarp that contains a large amount of lignin is in the middle. It tends to be stronger and harder than the peel, resulting in a difference in hardness and texture as a texture. In addition, since lignin and the like contained in the endocarp exist so as to surround the cells of the endocarp, as a result, the entire endocarp is isolated from the cell structure of the mesocarp, and the penetration of the seasoning is inhibited. . Therefore, it has been desired to develop a production method that can soften even the inner pericarp while preventing the mesocarp from collapsing in a short time, and can also adjust the hardness of the whole fruit.

  Also, when processing peach fruits, it is common to peel the outer skin. As a method of peeling the outer fruit skin, for example, there is a method of rinsing the skin while immersing the fruit in a heated sodium hydroxide aqueous solution and then exposing the fruit to water. However, this method has a problem that when the temperature of the aqueous sodium hydroxide solution is low, the skin is difficult to peel, and when the temperature is high, the flesh collapses. As another method for peeling the outer fruit skin, for example, a method in which the flesh is rapidly frozen and then the surface is melted with hot water of 25 ° C. to 60 ° C. to peel the skin by brushing, hydro brushing, or hand peeling is proposed. (See Patent Document 1). However, in this method, in the case of peaches before the hard nucleus period, the structure of the pectin in the middle of the pericarp and mesocarp is different from that of mature peach fruits, and the distinct structure of the pericarp cells and mesocarp cells is different. However, there was a problem that it was difficult to peel off because it was not configured.

Japanese Patent Laid-Open No. 57-118782

  The present invention has been made based on such a problem, can be softened to the inner skin while preventing collapse of the mesocarp in a short time, can also adjust the hardness of the whole fruit, Process for producing a peach processed food that can easily peel off the outer fruit skin while achieving uniform texture and texture of the mesocarp, endocarp and embryo, and suppressing crumble of the flesh, and processed peach food using the same Is to provide.

  The method for producing a processed peach food according to the present invention includes a freezing step of freezing peach fruits before the hard core period, and a frozen fruit that is immersed in an alkaline aqueous solution heated to 70 ° C. or higher and lower than the boiling point after the freezing step. And an outer skin peeling step for thawing only the surface of the fruit to peel the outer skin, and a heating step for heating the fruit after the outer skin peeling step.

  The processed peach food of the present invention is produced by the method for manufacturing a processed peach food of the present invention.

  In the present invention, the peach fruit before the hard nucleus period is frozen in the freezing step. Thereby, intracellular moisture freezes and crystallizes. At that time, the inner skin is harder and stronger than the mesocarp, so the cells are destroyed by the enlargement of ice crystals. On the other hand, the mesocarp has a softer and more elastic cell tissue than the endocarp, so that cell destruction is suppressed. Therefore, the texture and texture of the endocarp and mesocarp can be homogenized. In the outer skin peeling step, the frozen fruit is immersed in an alkaline aqueous solution heated to 70 ° C. or higher and lower than the boiling point, and only the surface of the fruit is thawed to peel the outer skin. Thereby, only the surface of a fruit reacts with alkaline aqueous solution, and collapse of a mesocarp is suppressed. Further, the fruit is heated in the heating step. At that time, since cell destruction by freezing is progressing in the endocarp, cell destruction is further promoted by heating. On the other hand, cell destruction by freezing is suppressed in mesocarp, so that cell destruction by heating is also suppressed.

  According to the present invention, since the peach fruit before the hard nucleus period is frozen, the cell destruction can be further promoted in the endocarp having a harder cell tissue than the mesocarp by the enlargement of ice crystals. Therefore, the inner skin can be softened while preventing the mesocarp from collapsing, and a base material that homogenizes the texture and texture of the inner skin and mesocarp can be made. In addition, manufacturing time can be greatly shortened, and manufacturing efficiency can be improved. Furthermore, the frozen fruit was immersed in an alkaline aqueous solution heated to 70 ° C. or higher and lower than the boiling point, and only the surface of the fruit was thawed to peel off the outer fruit skin. The peel can be peeled off. In addition, when heated, the texture and texture of the mesocarp, endocarp and embryo can be homogenized while adjusting the hardness of the whole fruit. In addition, the embryo existing inside the endocarp is not hard, but it becomes soft by heating, and the volume of the embryo is small from the whole fruit and has almost no effect on the texture and texture of the whole fruit.

  Furthermore, if the seasoning is soaked in the seasoning, the penetration rate of the endocarp is approaching the penetration rate of the mesocarp due to cell destruction. Can do. Therefore, homogenization of the seasoning concentration can be achieved.

It is sectional drawing showing the structure of the peach fruit before a hard nucleus period. It is a flowchart showing the process in the manufacturing method of the peach processed food which concerns on one embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The method for producing a processed peach food according to one embodiment of the present invention is for manufacturing a food processed from peach fruits before the hard nucleus period, and the processed peach food according to one embodiment of the present invention. Is obtained by the method for producing the processed peach food.

  FIG. 1 shows a method for producing a processed peach food according to an embodiment of the present invention and a structure of a peach fruit before the hard nucleus period used in the processed peach food. The peach fruit before the hard nucleus period has an outer skin 1 which is a thin pericarp on the outermost side, and a mesocarp 2 which is enlarged and turned into a pulp. There is an endocarp 3 and an embryo 4 inside the endocarp 3.

  The growth of peach fruit is divided into the juvenile stage (first hypertrophy stage), the hard nucleus stage (second hypertrophy stage), and the mature stage (third hypertrophy stage). The lignin content of the inner pericarp 3 increases as it approaches the hard nucleus stage from the fruit stage. Lignin is the main component of the cell wall of the woody structure, and the endocarp 3 is gradually isolated from the mesocarp 2. In the hard nucleus period, the enlargement of the mesocarp 2 is slow and the maturation period of the nucleus occurs, and the nucleus of the endocarp 3 hardens to become seeds. During the maturity period, volume growth and weight growth of the mesocarp 2 become active, and the sugar content increases and it becomes the harvest period.

  Processed peach fruits before the hard core period include, for example, honeydew, jam, honey, syrup, soy sauce, boiled in alcohol, pickled in syrup, pickled in vinegar, pickled in soy sauce, pickled in miso, pickled in miso, pickled in salt , Pickled mustard, dried fruit. The present invention is not limited to these exemplified processed foods, and can be applied to any processed food.

  FIG. 2 shows the steps of a method for producing a peach processed food according to an embodiment of the present invention. In this method for producing processed peach food, first, raw peach fruit before the hard nucleus period is frozen as it is (freezing step; step 110). Thereby, the water | moisture content in a fruit cell freezes and it crystallizes. At that time, since the inner pericarp 3 has a harder and stronger cell structure than the intermediate pericarp 2, the cells of the inner pericarp 3 are destroyed by the enlargement of ice crystals. In contrast, the mesocarp 2 is softer and more elastic than the inner pericarp 3, so that cell destruction is suppressed.

  The freezing may be quick freezing or slow freezing, but slow freezing is preferred. This is because the ice crystals can be enlarged and the cells of the inner skin 3 can be destroyed. Note that slow freezing is a freezing method in which a temperature range from 0 ° C. to −5 ° C. is passed over a time longer than 30 minutes, and quick freezing is a temperature range from 0 ° C. to −5 ° C. This is a refrigeration method that allows passage within 30 minutes.

  Next, the outer skin 1 of the fruit is peeled off (outer skin peeling step; step 120). Specifically, for example, the frozen fruit is immersed in an alkaline aqueous solution heated to 70 ° C. or higher and lower than the boiling point (alkaline aqueous solution immersion step; step 121), and only the surface of the fruit is thawed while thawing the outer skin 1 and the inside. The intermediate pectin with the skin 2 is dissolved by reacting with alkali (outer skin thawing step; step 122). This is because by immersing the frozen fruit in an alkaline aqueous solution heated to 70 ° C. or higher and lower than the boiling point, only the fruit surface can be quickly thawed and reacted with alkali. Thereby, the cell destruction of the mesocarp 2 is suppressed, and the collapse of the pulp is prevented. After that, the outer peel 1 is washed away by exposure to water (water washing step; step 123).

  As the alkaline aqueous solution, for example, a strong alkaline aqueous solution such as a sodium hydroxide aqueous solution is preferable. The concentration of the alkaline aqueous solution is preferably in the range of 0.5% by mass or more and 10% by mass or less, for example. This is because, if the concentration is low, it is difficult to peel the outer skin 1 easily, but it can be sufficiently peeled within this range without increasing the concentration more than necessary. The time for immersing the fruit in the alkaline aqueous solution is preferably, for example, in the range of 30 seconds to 300 seconds, and more preferably in the range of 45 seconds to 270 seconds. This is because if the time is short, the outer peel 1 cannot be peeled off sufficiently, and if the time is long, the mesocarp 2 is thawed and melted with alkali. The temperature of the alkaline aqueous solution in which the fruit is immersed is preferably 80 ° C. or higher, more preferably 85 ° C. or higher, and further preferably 90 ° C. or higher. This is because the outer skin 1 can be peeled off more easily in a short time without dissolving the mesocarp 2.

  Subsequently, for example, the washed fruit is immersed in room temperature water or an aqueous solution to thaw the whole fruit (total thawing step; step 130). That is, the thawing process is divided into two stages, the outer skin 1 is thawed in the outer skin thawing process, and the entire rest is thawed in the entire thawing process. At that time, it is preferable to use an antioxidant solution such as an ascorbic acid aqueous solution. This is because oxidation of the mesocarp 2 can be prevented together with the entire thawing process. After that, for example, the head of the fruit is cut off and the handle 5 is taken (pattern removing step; step 140). Subsequently, for example, it is preferable to prevent the cut-off portion from being oxidized by immersing the fruit from which the handle 5 has been removed, in an antioxidant solution such as a normal temperature or cooled ascorbic acid aqueous solution again.

  Subsequently, the fruit is heated, for example, in water or an aqueous solution to adjust the hardness of the whole fruit (heating step; step 150). At that time, cell destruction by freezing is progressing in the endocarp skin 3, and thus the cell destruction is further promoted by heating. In addition, since the mesocarp 2 is inhibited from cell destruction caused by freezing, cell destruction caused by heating is also inhibited. The heating temperature is preferably adjusted to, for example, 90 ° C. or more and less than the boiling point, for example, 98 ° C. or less. This is because it takes time when the temperature is low, and the mesodermal skin 2 tends to collapse when boiling. The heating time varies depending on the target hardness, but may be, for example, about 20 minutes to 150 minutes. The heating is preferably performed in an antioxidant solution such as an ascorbic acid aqueous solution. This is because oxidation of the mesocarp 2 can be prevented. Moreover, when it is desired to keep the color of the fruit surface as necessary, it is preferable to use a copper pan or to immerse the copper piece in water or an aqueous solution together with the fruit and heat it. This is because copper chlorophyll in which chlorophyll is fixed by copper can be obtained by the action of copper ions, and a bright yellow-green color can be achieved.

  Next, if necessary, the fruit is soaked in, for example, a seasoning and seasoned (seasoning step; step 160). Specifically, for example, the fruit is put in a packaging container such as a bottle, can, resin bag, or plastic container together with the seasoning and sealed. At that time, the permeation rate of the inner pericarp 3 approaches the permeation rate of the mesocarp 2 due to cell destruction. Subsequently, for example, the fruit is sterilized by heating until the center temperature of the fruit reaches about 80 ° C. (sterilization step; step 170). After that, it is cooled and stored until the ingredients of the seasoning have become familiar with the whole fruit and ripened (ripening step; step 180). Thereby, a peach processed food is obtained.

  In addition, you may make it perform a seasoning process, a heating process, and a sterilization process simultaneously. For example, the fruit and seasoning from which the handle 5 is taken may be put in a packaging container and sealed, and heated to adjust the hardness of the whole fruit and be sterilized.

  Thus, according to the present embodiment, since the peach fruit before the hard nucleus period is frozen, cell destruction due to the enlargement of ice crystals is caused in the inner pericarp 3 where the cell tissue is harder than the mesocarp 2. Can proceed. Therefore, the inner skin 3 can be softened while preventing the mesocarp 2 from collapsing, and a base material that homogenizes the texture and texture of the inner skin 3 and the mesocarp 2 can be made. In addition, manufacturing time can be greatly shortened, and manufacturing efficiency can be improved. Furthermore, the frozen fruit was immersed in an alkaline aqueous solution heated to 70 ° C. or higher and lower than the boiling point, and only the surface of the fruit was thawed to peel off the outer fruit skin. The peel 1 can be peeled off. In addition, if heated, the hardness of the entire fruit after cooking can be adjusted while homogenizing the texture and texture of the mesocarp 2, endocarp 3 and embryo 4.

  Furthermore, since the penetration rate of the seasoning with respect to the inner pericarp 3 approaches the permeation rate with respect to the mesocarp 2 due to cell destruction of the inner pericarp 3, if it is seasoned by soaking in the seasoning, the inner pericarp 3 and The concentration of the seasoning penetrating into the mesocarp 2 can be made similar. Therefore, homogenization of the seasoning concentration with respect to the whole fruit can be achieved.

(Example 1-1)
The raw peach fruit before the hard nucleus period was frozen to -23 ° C. or lower by slow freezing (freezing step; step 110). Next, the frozen peach fruit is immersed in an aqueous solution of sodium hydroxide having a concentration of 0.5 to 10% by weight heated to 70 ° C. or more and below the boiling point in a frozen state for 30 to 300 seconds, and only the surface is thawed. After reacting the outer skin 1 with alkali, the peach fruit was immediately exposed to water to wash out the outer skin 1 (outer skin peeling step; step 120). Subsequently, the peach fruit was immersed in an antioxidant solution to thaw the whole fruit and to prevent oxidation (total thawing step; step 130). After that, the head of the peach fruit was cut off and the handle 5 was removed (pattern removing step; step 140). Next, peach fruits were put in an antioxidant solution heated to 90 ° C. or more and less than the boiling point in a stainless steel pan, and the time was adjusted as necessary to heat for 20 to 150 minutes (heating step; step 150). Subsequently, the peach fruit is put in a packaging container together with a seasoning made of a sugar solution and sealed (seasoning step; step 160), and sterilized by heating until the center temperature of the peach fruit reaches about 80 ° C. (sterilization step). Step 170). After that, it was cooled and aged (aging process; step 180). As a result, processed peach food was obtained.

(Example 1-2)
Except having performed the seasoning process, the heating process, and the sterilization process simultaneously, others manufactured the peach processed food like Example 1-1. Specifically, like Example 1-1, after performing a freezing process, an outer skin peeling process, a whole thawing process, and a handle removing process, the fruit is put in a packaging container together with a seasoning made of a sugar solution and sealed. (Seasoning step) Next, the mixture was heated for 20 to 150 minutes in an atmosphere of 90 ° C. or higher and lower than the boiling point (heating step / sterilization step), cooled and aged (aging step).

(Comparative Example 1-1)
After immersing the raw peach fruit before the hard nucleus period in a sodium hydroxide aqueous solution having a concentration of 0.5 to 10% by weight heated to 70 ° C. or higher and lower than the boiling point, immediately immerse the peach fruit in 30 to 300 seconds. The outer skin 1 was washed away by exposure to water. Next, the head of the peach fruit was cut off and the handle 5 was removed, and then a peach processed food was prepared by adding a small amount of sugar solution every day and simmering for 4 days without boiling.

(Comparative Example 1-2)
A peach processed food was produced in the same manner as in Example 1-1 except that the freezing step was not performed and the heating time in the heating step was 20 minutes.

(Comparison between Examples 1-1 and 1-2 and Comparative Examples 1-1 and 1-2)
In the processed peach foods produced in Examples 1-1 and 1-2, the inner skin 3 was soft, and a uniform texture and texture were obtained between the inner skin 3 and the mesocarp 2. Moreover, the collapse of the mesocarp 2 was not seen. On the other hand, in Comparative Example 1-1, although the inner pericarp 3 was softened to some extent by being boiled for 4 days, the inner pericarp 3 and mesocarp 2 differed in texture and texture and the mesocarp 2 collapsed. Some were also seen. In Comparative Example 1-2, cell destruction of the endocarp 3 in the freezing process (step 110) was not performed, and therefore, compared with Examples 1-1 and 1-2, the endocarp 3 was harder and the taste oozing was poor. The mesocarp 2 was also hard. That is, according to the present embodiment, the inner skin 3 can be softened while preventing the mesocarp 2 from collapsing in a short time, and the texture and texture of the inner skin 3 and the mesocarp 2 can be homogenized. I understood.

(Example 2-1)
In the same manner as in Example 1-1, after performing the freezing step and the outer skin peeling step, a part of the fruit was taken out and cut into a mesocarp 2 and an inner skin 3 and the sugar content was measured. Subsequently, the heating process was performed about the remaining fruit similarly to Example 1-1. Subsequently, after immersing in a 50% by mass sugar solution at room temperature for 5 hours, the sugar content of the mesocarp 2 and the inner pericarp 3 was measured. The results are shown in Table 1.

(Comparative Example 2-1)
In the same manner as in Example 2-1, after performing the freezing step and the outer skin peeling step, a part of the fruit was taken out, and the sugar content was measured for the middle skin 2 and the inner skin 3. Next, without performing the heating step, the sugar content was measured for the mesocarp 2 and the inner pericarp 3 by immersing in a 50% by mass sugar solution at room temperature for 5 hours. The results are also shown in Table 1.

(Comparison between Example 2-1 and Comparative Example 2-1)
As shown in Table 1, in both Example 2-1 and Comparative Example 2-1, the sugar content after being immersed in the sugar solution for 5 hours is different between the inner pericarp 3 and the middle pericarp 2; In comparison, the sugar content of the endocarp 3 was low. This is considered to be because the penetration rate with respect to the inner pericarp 3 is lower than that of the intermediate pericarp 2 due to the lignin hardening action. However, according to Example 2-1, the sugar content after being immersed in the sugar solution for 5 hours is 23.2 degrees for the mesocarp 2 and 19.7 degrees for the inner skin 3 and the sugar content is sufficiently high. In contrast, in Comparative Example 2-1, the mesocarp 2 was as low as 14.5 degrees and the mesocarp 3 was as low as 9.3 degrees. That is, it was found that the cell destruction of the endocarp 3 can be promoted by the freezing step and the heating step, the texture and texture can be homogenized, and the seasoning concentration can be homogenized.

(Example 3-1)
A processed peach food was produced in the same manner as in Example 1-1 except that the raw peach fruit before the hard nucleus period was frozen to -35 ° C or lower by quick freezing. Similarly to Example 1-1, the processed peach food produced in Example 3-1 has a soft inner skin 3, and a texture and texture that are homogenized between the inner skin 3 and the mesocarp 2 are obtained. The mesocarp 2 was not broken. However, the hardness of the endocarp 3 was slightly felt in Example 3-1 compared to Example 1-1. That is, it was found that it is preferable to perform slow freezing in the freezing step.

(Example 4-1)
In the heating process, a peach processed food was produced in the same manner as in Example 1-1 except that a copper pan was used instead of the stainless steel pan. For the processed peach food produced in Example 4-1, the same texture and texture as in Example 1-1 were obtained. In Example 1-1, the fruit faded to a light brown color, whereas in Example 4-1, it remained vivid yellowish green. That is, when heated using a copper pan, it was found that the chlorophyll can be made into copper chlorophyll in which copper ions are fixed with copper ions, and the color can be vividly finished.

(Examples 5-1 to 5-4)
In the outer skin peeling process, the temperature of the 2 mass% sodium hydroxide aqueous solution in which the peach fruit is immersed is changed to 98 ° C., 90 ° C., 80 ° C., 70 ° C. A processed peach food was produced in the same manner as in Example 1-1, except for the above.

(Comparative Examples 5-1 to 5-3)
In the outer skin peeling process, the temperature of the 2% by mass sodium hydroxide aqueous solution for immersing the peach fruit was changed to 60 ° C., 50 ° C. and 40 ° C., and the immersion time was changed within the range of 1 to 10 minutes. Except for the above, a peach processed food was produced in the same manner as in Example 1-1.

(Comparison between Examples 5-1 to 5-4 and Comparative Examples 5-1 to 5-3)
According to each of Examples 5-1 to 5-4, the outer skin 1 was peeled off without any problem, and the mesocarp 2 was not broken. On the other hand, in Comparative Examples 5-1 to 5-3, when the soaking time is short, there is a residue, and when the soaking time is lengthened, the mesocarp 2 is collapsed, and the mesocarp 2 is not melted and the pericarp 1 is not melted. Could not be peeled off without remaining. That is, when immersed in an alkaline aqueous solution heated to 70 ° C. or higher and lower than the boiling point, it is understood that only the surface of the fruit can be thawed and the outer skin 1 can be easily peeled while preventing the mesocarp 2 from collapsing. It was. Moreover, when Examples 5-1 to 5-4 were compared, it was possible to easily peel the outer skin 1 in a shorter time when the temperature was increased. That is, it was found that the temperature range of the alkaline aqueous solution in which the fruit is immersed is preferably 70 ° C. or higher, more preferably 80 ° C. or higher, further 85 ° C. or higher, and further 90 ° C. or higher.

  Although the present invention has been described with reference to the embodiments and examples, the present invention is not limited to the above embodiments and examples, and various modifications can be made. For example, in the above-described embodiment, the manufacturing process has been specifically described. However, all the manufacturing processes may not be included, and other manufacturing processes may be included.

  Moreover, although the said embodiment demonstrated the case where the whole thawing | decompression process which thaw | decompresses the whole fruit was performed after peeling the outer skin 1 in an outer skin peeling process, for example, the outer skin 1 is made into water in an outer skin peeling process. A part or all of the fruit may be thawed when washed away by exposure.

  Furthermore, although the said embodiment demonstrated the case where the whole fruit was thawed and the heating process was performed after removing the handle 5, the peach partially frozen after the outer skin peeling process was replaced with water or an aqueous solution.
