When the food material to be processed is raw food material, the food material to be processed is prefabricated to obtain cooked food material.

In step 101, the food material to be treated is a cooked food material, the preset sugar-controlling scheme may be one or more of sugar-controlling schemes combining freeze-thaw treatment and starch retrogradation treatment in the following embodiments, and in addition, the preset sugar-controlling scheme may also be one or more of sugar-controlling schemes combining cooling treatment and starch retrogradation treatment in the following embodiments; when the food material to be treated is a raw food material, the preset sugar-controlling scheme further comprises a method for prefabricating the raw food material into a cooked food material, and the method for prefabricating the raw food material into the cooked food material is combined with one or more of the cooked food material sugar-controlling schemes.

Or the volume of the food material to be processed is obtained by combining the weight and the water content through calculation. However, the measuring method of the weight and the volume of the food material to be processed is not limited, and can be selected according to the requirement.

Referring to table 2, taking steamed breads with different water contents as an example, the water content of the steamed breads is generally about 45%, and the influence of the water content on the promotion rate and the sensory quality of the resistant starch is explained.

TABLE 2 influence of different water contents on sugar control and sensory quality

Generally, the food materials to be treated are exemplified by steamed bread, and tables 2 to 7 described below are exemplified by steamed bread. As shown in Table 2, the lower the water content is, the more unfavorable the retrogradation of starch is, the less favorable the resistant starch is, the too high or too low water content also affects the taste, the too low water content is coarse when eaten, and the too high water content is not soft enough when eaten.

Of course, the weight and volume of the food material has an effect on both the temperature and time of the freezing and melting process. Generally, the larger the weight of the food material, the longer the time required for the freezing treatment, and the lower the temperature, the longer the time required for the melting treatment; similarly, the larger the volume of the food material, the longer the time required for the freezing process, and the lower the temperature, the longer the time required for the melting process.

In some embodiments, it is understood that in step 102, i.e. in the step of determining the preselected sugar control regimen based on at least one of the preset sugar control regimen, the preset sugar control effect, the target sugar control regimen, and the target sugar control effect, the manner of determining the preselected sugar control regimen may be one of the following manners:

in the first mode, a preset sugar control scheme is automatically selected as a pre-selection sugar control scheme after a set time length. In the embodiment, the automatically selected preset sugar control scheme is a scheme suitable for the food materials to be processed, and can recommend the scheme for the user, so that the user operation is simplified.

The set time period may be 10 seconds, 1 minute, 10 minutes, 1 hour, or 10 hours, and the set time period may be a time period pre-stored in the system, or a time period manually set by a user.

In a second mode, one of a plurality of pre-set sugar control protocols is manually selected as the pre-selected sugar control protocol. In the embodiment, a manual selection mode is adopted by a user, and the user can select according to the preference. The manual selection may be: and performing input selection or click selection on executing equipment of the processing method of the starch-containing food material, or performing input selection or click selection on a mobile terminal. Of course, the manual selection may also be a result of a user selection by voice input.

The first mode and the second mode can be combined for use, a user can manually select a preset sugar control scheme as a pre-selection sugar control scheme within a set time length, and when the preset time length is reached, the user still does not select the preset sugar control scheme, and then the preset sugar control scheme is automatically selected as the pre-selection sugar control scheme. Of course, the user may also make manual modifications, overrides or pauses to the determined preselected glucose control profile.

In a third aspect, one or more parameters of a pre-set sugar control protocol are modified, and the modified sugar control protocol is used as a pre-selected sugar control protocol. The preset sugar control scheme is one or more schemes recommended according to the information of the food materials to be processed, different users have different requirements, and the users can modify parameters in the preset sugar control scheme so as to meet the requirements of the users.

And a fourth mode, acquiring a sugar control effect corresponding to the target sugar control scheme according to the target sugar control scheme, determining the target sugar control scheme as a preselected sugar control scheme according to the sugar control effect corresponding to the target sugar control scheme, or modifying one or more parameters in the target sugar control scheme according to the sugar control effect corresponding to the target sugar control scheme, and taking the modified sugar control scheme as the preselected sugar control scheme.

The method comprises the steps of obtaining a sugar control effect corresponding to a target sugar control scheme according to the target sugar control scheme, namely obtaining the sugar control effect according to the target sugar control scheme after a user sets the target sugar control scheme, setting the target sugar control scheme as a pre-selection sugar control scheme by referring to the sugar control effect after the user obtains the sugar control effect through an execution device or a mobile terminal, or adjusting one or more parameters in the target sugar control scheme and obtaining the sugar control effect again by the user, and taking the adjusted sugar control scheme as the pre-selection sugar control scheme when the sugar control effect reaches the expectation of the user to meet the sugar control requirement of the user.

And in a fifth mode, one or more preset sugar control schemes are recommended according to the target sugar control effect, and one preset sugar control scheme is automatically or manually selected as a preselected sugar control scheme, so that the sugar control effect of the preselected sugar control scheme can meet the requirement of a user. The automatic selection refers to the first manner, and the manual selection refers to the second manner.

The five manners for determining the preselected sugar control scheme can be selected according to the requirement, and the five manners can be combined with each other or a plurality of combinations, but the manners for determining the preselected sugar control scheme are not limited to the five manners, and other manners are also possible, which are not listed here.

It is understood that the predetermined sugar-controlling effect includes: one or more parameters of a resistant starch content, a resistant starch content increase rate, and a resistant starch content increase rate at a preset time point or a preset time period.

The preset sugar control effect is a result obtained by performing a test according to a preset sugar control scheme, that is, parameters such as resistant starch content, resistant starch content increase rate, and resistant starch content increase rate in the preset sugar control effect may be data measured and stored in advance. The preset sugar control effect can be stored in the execution equipment, the mobile terminal or a cloud database and the like.

The relationship between the parameters such as the resistant starch content, the resistant starch content increase rate and the time can be a pre-stored data list or a pre-stored data chart and the like. The data list may be a point value corresponding to a preset time point or a range value corresponding to a preset time period, and the data chart may be a histogram, a graph, or the like.

It is understood that the target sugar control effects include: one or more of a resistant starch content, a rate of increase in resistant starch content, and a rate of increase in resistant starch content at a target time point or a target time period.

The resistant starch content increasing rate of the target sugar control effect may be calculated according to pre-stored data, and it may be understood that, when a sugar control scheme is executed, a real-time stage of the sugar control scheme corresponds to a preset stage of a most matched preset sugar control scheme, and the resistant starch content increasing rate of the preset stage may be used as the resistant starch increasing rate of the real-time stage. Similarly, the resistant starch content increase rate can also be obtained by adopting the method; the resistant starch content needs to be calculated by combining the increase rate of the resistant starch content with the weight of the food material to be treated.

The target sugar control effect is set according to the user requirement, when the user sets the target sugar control effect, the target sugar control effect corresponds to the preset sugar control effect, so that a corresponding sugar control scheme is provided according to the target sugar control effect set by the user, and the sugar control requirement of the user is further met.

It will be appreciated that in step 102, i.e. in the step of determining the pre-selected sugar control regimen based on at least one parameter of the pre-set sugar control regimen, the pre-set sugar control effect, the target sugar control regimen and the target sugar control effect,

the preset sugar control scheme comprises the following steps:

cooling the food material to be processed to obtain a first pre-processed cooked food material;

the first pre-treated cooked food material is maintained at a first preset temperature for a first preset time period to retrogradation starch in the first pre-treated cooked food material.

The step of cooling treatment can be implemented by various embodiments, such as uniform cooling, segmented cooling, and the like. It is to be understood that uniform cooling generally refers to cooling by a constant cooling rate, and staged cooling generally refers to cooling by multiple stages. It should be noted that the aim of cooling in the above-described manner after cooking the food material to be treated is that after gelatinization of the starch, the crystalline structure is destroyed and the amylose molecules escape into the water, and during the cooling treatment, the amylose molecules can gradually approach each other and form a double helix through intermolecular hydrogen bonds, resulting in larger and more stable amylose crystals.

When the food material to be treated is raw food material, cooling the raw food material after the raw food material is cooked; when the food material to be treated is a cooked food material, the cooked food material is directly cooled. Specifically, in the process of cooling by stages, the number of stages, the stage temperature corresponding to each stage, the cooling rate of each stage, and the retention time of the stage temperature corresponding to each stage are not specifically limited, and can be set according to actual needs to form various combinations. And cooling at a constant speed according to a set cooling rate.

In the cooling process, a first cooling rate of the food material to be processed from the initial temperature to a second preset temperature can be determined according to the initial temperature of the food material to be processed (after cooking). When the food material to be processed is a food material which is just cooked, the initial temperature of the food material to be processed is higher, for example, the initial temperature is 100 ℃, the second preset temperature of the freezing process is-5 ℃, at this time, the first cooling rate can be 5 ℃/min, and the temperature is cooled to the second preset temperature in about 20 min. When the food material to be processed is cooked and cooled to room temperature, the initial temperature of the food material to be processed can be understood as 20 ℃, the second preset temperature of the freezing process is-5 ℃, the first cooling rate can be 2 ℃/min, and the temperature is cooled to the second preset temperature in about 10 min.

It will be appreciated that, referring to FIG. 3, in step 102, i.e. in the step of determining a pre-selected sugar control profile based on at least one parameter of the pre-set sugar control profile, the pre-set sugar control effect, the target sugar control profile and the target sugar control effect,

the preset sugar control scheme comprises the following steps:

step 301, performing freeze thawing treatment, namely performing freeze thawing treatment on the food material to be treated to obtain a first pre-treated cooked food material, wherein the freeze thawing treatment comprises freezing treatment for a first preset number of times and melting treatment for a second preset number of times;

wherein the freezing process is understood to be cooling the food material to be processed to below 0 ℃ so that the water in the food material to be processed is frozen into ice crystals, and the melting process is understood to be heating the cooked material to be processed in a frozen state to above 0 ℃ so that the ice crystals in the food material to be processed are melted into water. The initial state of the food material to be treated is generally a non-frozen state at normal temperature (ambient temperature, generally 20 ℃) or high temperature (just cooked), the food material to be treated is frozen firstly and then melted, water molecules in the starch granules can form ice crystals in the process of freezing treatment, and the water migration and phase separation in the starch can be caused by melting treatment, so that the starch molecules in the starch granules are promoted to be aggregated and recrystallized, and the first pre-treated cooked food material is obtained.

The numerical values of the first preset times and the second preset times are not limited and can be selected according to needs, for example, the first preset times and the second preset times are both one time or both times.

Step 302, starch aging and retrogradation treatment, wherein the first pre-treated cooked food material is kept at a first preset temperature for a first preset time period, so that starch in the first pre-treated cooked food material is retrograded.

Combining the above, freezing treatment and melting treatment to promote partial amylopectin to separate to form amylose, during the aging and retrogradation process of the starch, the amylose in the first pre-treated cooked food material in a melting state is recombined to form resistant starch, namely amylose molecules in the food material to be treated can gradually approach each other and form double helix through intermolecular hydrogen bonds to form bigger and more stable amylose crystals, and the amylose crystals have good thermal stability and are not easy to be decomposed and damaged by enzyme, namely the resistant starch. The resistant starch is more difficult to degrade than other starches, is slowly digested in vivo, is slowly absorbed and enters blood, has the property similar to soluble fiber, and is not easy to be absorbed by human bodies, thereby achieving the effect of controlling sugar.

Wherein the first pre-treated cooked food material is transformed from a frozen state to a thawed state or the first pre-treated cooked food material is in a thawed state. The state of the first pre-processed cooked food material is related to the first preset number and the second preset number, and reference may be made to the following embodiments.

The first preset temperature and the first preset time length can be selected according to different food material characteristics of the first pre-processed cooked food material and different target sugar control effects. The resistant starch content and the corresponding optimal starch retrogradation conditions of different types of cooked food are different, but the pre-treatment can be carried out by combining freezing treatment and melting treatment.

According to the processing method of the starch-containing food material, the food material to be processed is preprocessed by combining freezing processing and melting processing (namely freezing and thawing processing) to obtain the first preprocessed cooked food material, the first preprocessed cooked food material is subjected to starch aging and retrogradation processing to promote part of starch in the food material to be processed to be converted into resistant starch which is difficult to digest and absorb, the resistant starch in the food material is increased, digestion can be promoted, satiety is promoted, the influence on blood sugar of a human body is small, and the purpose of scientific sugar control is achieved. In addition, the process only carries out physical treatment on the starch in the food material to be treated, nutrient substances such as vitamins and amino acids in the food material to be treated are not damaged, other ingredients in the food material to be treated cannot be influenced, potential safety hazards do not exist, and better mouthfeel can be kept.

In the related art, the resistant starch is not digested and absorbed by the small intestine of the human body, so that the resistant starch is fermented and utilized by microorganisms in the large intestine. Therefore, it can be understood that after the content of the resistant starch in the first pretreated cooked food is increased, the effect of controlling the increase of blood sugar can be achieved for a user, and the effect of regulating intestinal bacterial colonies can also be achieved for the user. In addition, the food materials pretreated by the method provided by the embodiment of the invention are suitable for diabetes patients, hyperlipidemia patients and weight-losing and slimming people, and the embodiment belongs to a physical modification method, so that the safety is better, and the pretreatment process can not cause the loss of nutrient substances.

It is understood that in the freezing and thawing process of step 301, the first predetermined number of times is an integer of 2 or more, and the freezing process and the thawing process are alternately performed.

The first preset number is greater than or equal to two times, the second preset number can be equal to or less than the first preset number, but the second preset number is not greater than the first preset number, and the specific number can be selected according to needs. When the second preset times is equal to the first preset times, freezing and melting the food material to be processed for the same times, and after the last melting is finished, performing the starch aging and retrogradation treatment; when the second preset number is less than the first preset number, and after the last freezing treatment is completed, the starch retrogradation treatment is directly performed without melting treatment, wherein the food material to be treated can be melted in the starch retrogradation treatment process, and an independent melting treatment process is not performed, so that the treatment process of the food material to be treated can be simplified.

The freezing treatment and the melting treatment are sequentially repeated, and the times of the freezing treatment and the melting treatment are not limited. Repeated freezing and melting can ensure that starch molecules in the food material to be treated have enough time for rearrangement and orientation, promote the recrystallization of the starch molecules and further improve the generation rate of resistant starch.

The first pre-treated cooked food material is obtained by matching freezing treatment and melting treatment which are alternately carried out, and has important influence on retrogradation of starch in the first pre-treated cooked food material. The alternating freezing treatment and melting treatment are matched, so that the aging and retrogradation of the starch in the first pre-treated cooked food material can be accelerated, and the generation rate of the resistant starch in the first pre-treated cooked food material can be improved.

It will be appreciated that the step 301 of freeze-thaw treatment and the step 302 of starch retrogradation treatment are cycled.

When the freeze-thaw treatment comprises one-time freezing treatment and one-time thawing treatment, and the starch aging retrogradation treatment is performed after the freeze-thaw treatment is completed, at this time, the treatment process of the starch-containing cooked food material can be considered to be completed once, the treatment time is short, and the instant eating by a user is facilitated. Or, the above-mentioned treatment process of the starch-containing cooked food material, i.e., the freeze-thaw treatment and the starch retrogradation treatment, is performed for a plurality of times in a circulating manner, and the time of the plurality of times of treatment is increased, but the conversion rate of digestible starch into resistant starch which is difficult to digest is higher after the plurality of times of treatment.

When the freeze-thaw treatment includes multiple times of freezing treatment and at least one time of thawing treatment, and starch retrogradation treatment is performed after the freeze-thaw treatment is completed, it can be considered that a treatment process of the starch-containing cooked food material is completed, and in this process, the multiple times of freezing treatment and the at least one time of thawing treatment can promote digestible starch molecules to have enough time to rearrange and recrystallize. Or, the treatment process of the starch-containing cooked food material is performed repeatedly, wherein in each treatment process of the starch-containing cooked food material, the freeze-thaw treatment comprises multiple times of freezing treatment and at least one time of thawing treatment, so as to promote recrystallization of digestible starch molecules; the treatment time is increased by the treatment process of the starch-containing cooked food material for a plurality of times, but the conversion rate of digestible starch into resistant starch which is difficult to digest is higher after the treatment for a plurality of times.

It is understood that, referring to fig. 4, in step 301, the step of freeze-thaw treatment includes the following steps:

step 3011, freeze processing, the freeze processing including: and the food material to be processed is kept at the second preset temperature for a second preset time, and the second preset temperature is less than or equal to 0 ℃.

In some of these embodiments, the second predetermined temperature is defined as less than or equal to 0 ℃. It will be appreciated that cooling to below 0 ℃ is one of the necessary conditions in order to form ice crystals from the water molecules in the starch granules in the food material to be treated. The specific value of the second preset temperature is not particularly limited, and is, for example, -3 ℃ to-18 ℃. In addition, specific values of the second preset time period are not particularly limited, for example, 1h to 6 h. It will be appreciated that the longer the second predetermined period of time, the greater the number of ice crystals formed by water molecules in the starch granules in the food material to be treated. Further, the freezing rate (i.e. the rate of cooling from the current temperature to the second preset temperature) in the freezing process also affects the retrogradation speed of the starch, and the slower freezing rate increases the cross-linking and water separation of starch molecules, which is beneficial to retrogradation of the starch.

Step 3012, performing a thawing process, wherein the thawing process comprises: and heating the frozen food material to be processed from the second preset temperature to a third preset temperature and continuously melting the frozen food material for a third preset time, wherein the third preset temperature is more than 0 ℃.

In some of these embodiments, the third predetermined temperature is defined as being above 0 ℃. It can be understood that, in order to dissolve the ice crystals formed in step 3011, heating them to a temperature higher than 0 ℃ is one of the necessary conditions, and the melting process causes water migration and phase separation in the starch, thereby promoting starch molecule aggregation in the starch granules, facilitating formation of starch nuclei, promoting starch molecule recrystallization, allowing the food material to be treated to regenerate, and increasing the resistant starch production rate. The specific value of the third preset temperature is not particularly limited, and is, for example, 2 ℃ to 25 ℃. In addition, specific values of the third preset time period are not particularly limited, and are, for example, 1h to 6 h. It can be understood that the longer the third predetermined period of time is, the better the aggregation of the starch molecules occurs, and the more favorable the formation of starch nuclei, and thus the recrystallization of the starch molecules is promoted.

It can be understood that, before the step 101, food material information of the food material to be processed is obtained;

the food material information can be understood as: one or more of a type, a moisture content, a volume, a weight, and an initial temperature of the food material.

Determining the processing conditions of freeze-thaw processing according to the food material information of the food material to be processed; the processing conditions of freeze-thaw processing are determined according to the food material information, sugar control can be performed in a targeted manner, a sugar control scheme and a sugar control effect are optimized, and user experience is improved.

Wherein, the processing conditions of the freeze-thaw treatment comprise: at least one of conditions that the freezing process can be set and conditions that the melting process can be set, such as a second preset temperature, a second preset time period, a cooling rate of the freezing process, a first preset number of times, a third preset temperature, a third preset time period, a heating rate of the melting process, a second preset number of times, and the like.

Certainly, the processing conditions of the starch aging and retrogradation processing can also be determined according to the food material information of the food material to be processed; the processing conditions of the starch retrogradation treatment comprise a first preset temperature and a first preset time length.

It can be understood that the step of obtaining the food material information of the food material to be processed includes: obtaining the variety of the food material to be processed.

Determining the treatment conditions of freeze-thaw treatment according to the variety of the food material to be treated. That is, the freeze-thaw treatment condition of step 301 is determined according to the type of the food material to be treated, and at this time, the condition for retrogradation of starch in step 302 is not limited, and the conditions in the following embodiments or the determination according to the type of the food material to be treated may be selected, and will not be described herein again.

When the second preset temperature and/or the third preset temperature are/is determined according to the type of the food material to be processed, the components of the food materials are different and the internal structures of the food materials are different, so that different food materials have different sugar control effects, and the sugar control processing conditions can be adjusted according to different food material information.

It is understood that in the steps of the freeze-thaw treatment and the starch retrogradation treatment, the freeze-thaw treatment conditions and/or the starch retrogradation treatment conditions are determined according to one or more of the kind, the moisture content, the volume and the weight of the food material to be treated.

For example, the conditions for the freeze-thaw treatment are determined according to the combination of at least one of the moisture content, the volume and the weight of the food material to be treated and the type, that is, the conditions for determining the second preset temperature according to the food material to be treated include: the type and the moisture content are combined, the type and the volume are combined, the type and the weight are combined, the type and the moisture content and the volume are combined, the type and the moisture content and the weight are combined, the type and the volume and the weight are combined, and the type and the moisture content, the volume and the weight are combined to ensure the freezing effect of the food materials to be processed, two or more food material information is combined, and the setting of the second preset temperature is more accurate. Similarly, the third preset temperature of the melting process is also determined according to the combination mode of the two or more food materials, so that the setting of the third preset temperature of the melting process is more accurate.

Of course, the conditions of the freeze-thaw treatment are determined according to one or more of the moisture content, the volume and the weight of the food material to be treated and the type, and may include a second preset temperature, a third preset temperature, and at least one of a second preset time, a third preset time, a first preset number of times and a second preset number of times. Meanwhile, the starch retrogradation treatment conditions can also be determined jointly according to one or more of the water content, the volume and the weight of the food material to be treated and the type, such as at least one of the first preset temperature and the first preset time.

In some embodiments, it is understood that the second predetermined temperature ranges from-5 ℃ to 0 ℃ and the second predetermined time period ranges from 0.5h to 4h in step 3011. The lower the second preset temperature is, the faster the freezing rate of the freezing treatment is, and the shorter the required second preset time is, so that the time of the freezing-thawing treatment is favorably shortened, and the treatment efficiency is improved.

In some embodiments, it is understood that the third predetermined temperature is in the range of 2 ℃ to 25 ℃ and the third predetermined time period is in the range of 0.5h to 4h in step 3012. The third predetermined temperature is preferably a temperature at which the food material to be processed is changed from a frozen state to a melted state without deteriorating the food material to be processed. The higher the third preset temperature is, the faster the melting rate of the melting treatment is, and the shorter the third preset time is, so that the time of the freezing and thawing treatment is favorably shortened, and the treatment efficiency is improved.

With reference to the above embodiments, the second predetermined temperature is in the range of-5 ℃ to 0 ℃, which is understood to mean that the second predetermined temperature is maintained in the temperature range of-5 ℃ to 0 ℃, or the second predetermined temperature is at a temperature point in the range of-5 ℃ to 0 ℃. The third predetermined temperature is in the range of 2 ℃ to 25 ℃, and may be understood as the third predetermined temperature being maintained in the temperature range of 2 ℃ to 25 ℃, or the third predetermined temperature being a temperature point in the range of 2 ℃ to 25 ℃. When the melting process is carried out in a refrigerating chamber of the refrigerator, the third preset temperature can be selected to be 4 ℃, so that the food material to be processed can be guaranteed to be melted, the circulating air of the refrigerating chamber can be utilized, and the structure of the refrigerator can be simplified.

As shown in Table 3 below, the second preset temperature of the freezing treatment was measured at-10 ℃ to 0 ℃ under otherwise identical conditions, and the following test results were obtained.

TABLE 3 Effect of the second Preset temperature on sugar control and sensory quality

Referring to table 3, generally, the freezing point temperature of food materials to be processed (taking steamed buns as an example, and taking steamed buns as examples from table 2 to table 7 below) is-3 to 0 ℃, and the freezing process in the freeze-thaw stage is performed as long as the temperature can completely freeze the moisture in the staple food, so that the moisture migration in the thawing link is completed, and the resistant starch is improved; and the subsequent continuous temperature reduction has no obvious effect on the improvement of the effect, so that the improvement effect of the resistant starch has no obvious change when the temperature is lower than-5 ℃, and the effect can be realized at the temperature of-5-0 ℃.

In some embodiments, the first predetermined number and the second predetermined number are not limited thereto. However, it is understood that the greater the preset number of times of freeze-thaw treatment (the greater the first preset number of times and the second preset number of times), the better the retrogradation effect of the food material to be treated. The freeze-thaw process (i.e., the multiple freezing processes and the at least one thawing process) is performed by repeating

steps

3011 and 3012 of the above embodiment multiple times without interruption. In the process of freeze thawing treatment, water molecules in the food materials to be treated are frozen into ice crystals for many times and then dissolved into water, so that the starch molecules in the starch granules are promoted to be aggregated, the formation of starch crystal nuclei is facilitated, the retrogradation of the food materials to be treated is promoted, the generation rate of resistant starch is improved, and the blood glucose reducing effect of the food materials to be treated is improved.

It will be appreciated that upon completion of the first predetermined number of freezing processes (the last step 3011 is complete, i.e., the second predetermined number of melting processes is complete), the first pre-processed cooked food material is warmed from the second predetermined temperature to the first predetermined temperature. That is, the final freezing treatment is completed without performing the thawing treatment, and the first pre-treated cooked food material can be thawed by the starch retrogradation treatment, thereby simplifying the treatment steps.

At this time, the first preset number is a positive integer greater than or equal to 2, and the second preset number is smaller than the first preset number by 1.

In some embodiments, it is understood that, in step 301, the first preset number of times is determined according to the type of the food material to be processed, and the first preset number of times may be 1-5 times.

Referring to table 4, in the case that other conditions are consistent, the first preset number of times is tested according to 1 to 6 times, and the following test results are obtained.

TABLE 4 influence of the first predetermined number of times on the sugar control and sensory quality

When the first preset number of times of freezing is 1, the second preset number of times of melting is 1, and when the first preset number of times of freezing is 2-6, the second preset number of times of melting can be the same as the first preset number of times, or the second preset number of times is less than the first preset number of times. In the test shown in table 4, when the first preset number of times of freezing treatment is 2 to 6 times, the second preset number is smaller than the first preset number of times. Referring to table 4, the more times of freezing and melting treatment is beneficial to the generation of resistant starch, but the generation of resistant starch is not significantly improved after a certain number of times is reached, the mouthfeel becomes worse with the increase of the number of times, 1-5 times of comprehensive selection is better, and the sugar control time is also beneficial to be shortened.

In some embodiments, it is understood that the first preset temperature is less than or equal to a third preset temperature and the first preset duration is greater than or equal to a third preset duration. The first pre-treated cooked food material is kept at a first preset temperature for starch retrogradation, the first preset temperature is a temperature value or a temperature range required by starch retrogradation, and the first preset temperature is generally limited to 2-10 ℃. After the food material to be processed is frozen, the food material is melted at a third preset temperature, and the higher the third preset temperature is, the higher the melting rate is, so that the process of melting treatment is favorably shortened.

It will be appreciated that the first predetermined temperature is defined to be between 2 ℃ and 10 ℃ in order to allow retrogradation of the starch in the first pre-treated cooked food material. The first pre-treated cooked food material subjected to freeze thawing treatment is subjected to heat preservation within a first preset temperature range, so that the rice has the advantages of optimal retrogradation effect and highest retrogradation efficiency, the generation rate of resistant starch in unit time is favorably improved, and the blood glucose reducing effect of the pre-treated rice is better. The first preset temperature is in the range of 2-10 ℃, and can be understood as the first preset temperature is kept in the temperature range of 2-10 ℃ or the first preset temperature is a temperature point in the range of 2-10 ℃.

Specifically, as shown in table 5, the first preset temperature was measured at 0 ℃, 2 ℃, 4 ℃, 8 ℃ and 10 ℃ under otherwise identical conditions, and the following test results were obtained.

TABLE 5 influence of the first Preset temperature on the sugar control Effect and sensory quality

As shown in table 5, the first preset temperature for retrogradation of starch is 2-10 ℃, wherein the first preset temperature is 4 ℃ and has the best effect of reducing blood glucose compared with other temperature points, and in addition, the first preset temperature is 2 ℃ and can achieve a better effect, but the first preset temperature is 8-10 ℃ and has relatively poorer effect but has little difference, wherein 0 ℃ is the worst. Wherein, in the test process, the second preset times is also 1 time.

Generally, the third preset temperature is also 4 ℃, so that the melting efficiency can be ensured, and the quality of food materials can be ensured.

In general, the value of the first preset time period is not particularly limited. It can be understood that under the same conditions, the longer the first preset time period is, the better the retrogradation effect of the first pre-treated cooked food material is, and the higher the generation rate of resistant starch is, the better the blood glucose reducing effect is.

It can be understood that the range of the first preset time is 4 h-24 h, the longer the first preset time for aging and retrogradation of starch is, the greater the aging and retrogradation degree is, the better the sugar control effect is, but the greater the influence on the appearance quality of the cooked staple food to be treated is, and the range of the first preset time is 4 h-24 h is helpful for keeping better sensory score and mouthfeel.

Referring to table 6, in the case that other conditions are consistent, the first preset time period is tested for 4h, 8h, 12h, 16h, 20h and 24h, and the following test results are obtained.

TABLE 6 influence of the first predetermined duration on the sugar control effect and sensory quality

The preset sugar control scheme has various adjustable parameters, so that the preselected sugar control scheme has diversity and can be suitable for various food materials and various requirements of users.

It is understood that in the above embodiment, the step 102 of determining the preselected sugar control scheme according to at least one of the preset sugar control scheme, the preset sugar control effect, the target sugar control scheme and the target sugar control effect comprises:

when the target sugar control protocol includes the freeze-thaw process of step 301 and the retrogradation process of starch of step 302 as described above,

parameters of the target sugar control protocol include: one or more of a target duration of freezing treatment, a target duration of thawing treatment, a total target duration of freezing and thawing treatment, a target duration of starch retrogradation, and a total target duration of sugar control process.

Wherein the total target duration of the freeze-thaw treatment may be understood as: the sum of the target time period of the freezing process and the target time period of the thawing process. The total target duration of the sugar control process may be understood as: the sum of the target duration of the freezing treatment, the target duration of the melting treatment and the target duration of the retrogradation of the starch.

the food material to be treated is a pre-prepared cooked food material. The cooked food material is directly subjected to sugar control treatment.

It can be further understood that, in step 101, that is, in the step of obtaining the preset sugar control scheme and the preset sugar control effect corresponding to the preset sugar control scheme according to the information of the food material to be processed,

the method comprises the following steps of (1) cooling or freezing and thawing the food material to be treated, wherein the steps comprise: the cooked food material is obtained by performing a pre-preparation treatment on raw food materials. After the raw food material is prefabricated into cooked food material, sugar control treatment is carried out; the preset sugar control scheme comprises the step of obtaining cooked food materials through the prefabrication treatment of the food materials.

It can be understood that, in the step of preparing the cooked food material from the raw food material:

when the food material to be processed is cereals, heating the raw food material in a water environment at a fifth preset temperature for a fourth preset time to gelatinize the raw food material; the term "heating" is understood to mean steaming, boiling, such as steaming rice, boiling rice or steamed bread. Of course, the cooked rice is not limited to rice, but may be coarse cereal rice, and may also be sweet potatoes such as sweet potatoes, Chinese yams, potatoes and the like.

When raw rice is gelatinized and heated, the rice of the same kind has a standard value of the initial gelatinization temperature, for example, 60 ℃ to 65 ℃. When the rice reaches its initial gelatinization temperature, the rice begins to gelatinize; therefore, the fifth preset temperature is defined to be not lower than the initial gelatinization temperature of the kind of rice used in order to gelatinize the rice so that the digestible and absorbable starch in the rice is dissolved in water. In addition, the value of the fifth preset temperature is not particularly limited so as to ensure that the value is not lower than the initial gelatinization temperature of the rice of the used type, for example, 60-80 ℃; under the condition that the rice is gelatinized, the higher the fifth preset temperature is, the higher the gelatinization degree of the rice is, but if the fifth preset temperature is higher, the influence on the appearance quality of the pretreated rice is larger, and the sensory qualities of the appearance, the mouthfeel, the softness and the fragrance and the like of the pretreated rice after being cooked into the rice are poorer. The value of the fourth preset time period is not particularly limited, for example, 10min to 60min, and may be determined according to the actual situation. It is understood that, when the fourth preset period of time is longer, the gelatinization degree of the rice is higher, the digestible and absorbable starch in the rice is dissolved in water in a larger amount, and the dissolution efficiency is higher. Therefore, the gelatinization degree of the rice can be controlled by reasonably controlling the fifth preset temperature and the fourth preset time, so that the blood sugar reducing effect of the pretreated rice is ensured, and the good sensory quality of the rice can be maintained.

and when the food material to be processed is cooked wheaten food or rhizome food material, the raw food material is cooked or baked at a sixth preset temperature for a fifth preset time.

secondly, the starch retrogradation stage (cold storage recrystallization stage): keeping the cooked staple food subjected to freeze-thawing treatment at a first preset temperature T1 for a first preset time T1, and allowing starch to age and regenerate to generate resistant starch; in order to ensure that the starch molecules have enough time to rearrange and orient, promote the recrystallization of the starch molecules, improve the aging efficiency and further improve the generation rate of resistant starch;

wherein the first preset temperature T1 is 2-10 ℃, and the first preset time T1 is 4-24 hours; the longer the time is, the larger the aging degree is, the better the sugar control effect is, but the influence on the appearance quality of the cooked staple food is larger, the aging degree needs to be strictly controlled, and the better taste can be kept while the sugar control effect is ensured;
