[0056] Example 2

[0057] In order to improve the leakage of donkey-hide gelatin explosive beads and highlight the effect of the encapsulation liquid on the morphology or state, the same preparation parameters as in Example 1 were used to analyze the effect of the encapsulation liquid on the morphology or state.

[0058] Step 1: prepare a coagulation bath, dissolve 1% sodium alginate in water, and defoam for later use;

[0064] Depend on Figure 1 It can be seen that the diameter of the popping beads prepared by Example 2 is 5 mm. After being stored at 37 degrees for 40 days, the color of the popping beads changed from amber to white, and the leakage of donkey-hide gelatin was serious.

[0065] Example 3

[0066] In order to improve the leakage of donkey-hide gelatin beads and highlight the effect of donkey-hide gelatin concentration on morphology or state, the same preparation parameters as in Example 1 were used to analyze the effect of donkey-hide gelatin concentration on morphology or state.

[0067] Three groups of donkey-hide gelatin beads were prepared, named donkey-hide gelatin 1, donkey-hide gelatin 2 and donkey-hide gelatin 3, respectively, according to the following steps:

[0068] Step 1: prepare a coagulation bath, dissolve 1% sodium alginate in water for each of donkey-hide gelatin 1, donkey-hide gelatin 2 and donkey-hide gelatin 3, and defoam and set aside for use;

[0069] Step 2: preparing a core material liquid, dissolving 10%, 20% and 30% of donkey-hide gelatin 1, donkey-hide gelatin 2 and donkey-hide gelatin 3 respectively and 7% of calcium lactate in water to obtain a core material stock liquid, and mixing 6% of hydroxypropyl distarch phosphate with the core material stock liquid to obtain a core material liquid;

[0072] Step 5 is to perform spheroidization. The coagulation bath of donkey-hide gelatin 1, donkey-hide gelatin 2 and donkey-hide gelatin 3 is stirred to keep the coagulation bath flowing, and then the core material liquid is dropped into the coagulation bath to spheroidize for 10 minutes to obtain primary donkey-hide gelatin beads;

[0073] Step 6 is to perform encapsulation, wherein the primary donkey-hide gelatin beads of donkey-hide gelatin 1, donkey-hide gelatin 2 and donkey-hide gelatin 3 are placed in the encapsulation liquid, and are continuously stirred and encapsulated for 12 minutes to obtain encapsulated donkey-hide gelatin beads;

[0074] Step 7 is sterilization treatment. The donkey-hide gelatin 1, donkey-hide gelatin 2 and donkey-hide gelatin 3 are all sterilized and packaged to obtain finished donkey-hide gelatin bursting beads.

[0075] The obtained beads were placed in a 37°C incubator for storage experiments. The results were as follows: Figure 2 .

[0076] Depend on Figure 2 It can be seen that the higher the concentration of donkey-hide gelatin, the darker the color of the popping beads prepared by Example 2. After storage at 37 degrees for 40 days, the color of the popping beads changed from amber to white.

[0077] Example 4

[0078] In order to improve the leakage of donkey-hide gelatin beads and highlight the effect of hydroxypropyl distarch phosphate concentration on the morphology or state, the same preparation parameters as in Example 1 were used to analyze the effect of hydroxypropyl distarch phosphate concentration on the morphology or state.

[0079] Four groups of donkey-hide gelatin beads were prepared, named hydroxypropyl distarch phosphate 1, hydroxypropyl distarch phosphate 2, hydroxypropyl distarch phosphate 3 and hydroxypropyl distarch phosphate 4, respectively, according to the following steps:

[0080] Step 1: prepare a coagulation bath, dissolve hydroxypropyl distarch phosphate 1, hydroxypropyl distarch phosphate 2, hydroxypropyl distarch phosphate 3 and hydroxypropyl distarch phosphate 4 in water with 1% sodium alginate, and defoam and set aside;

[0081] Step 2: preparing a core material liquid, dissolving 10% of donkey-hide gelatin and 7% of calcium lactate in water for each of hydroxypropyl distarch phosphate 1, hydroxypropyl distarch phosphate 2, hydroxypropyl distarch phosphate 3 and hydroxypropyl distarch phosphate 4 to obtain a core material stock liquid, and mixing 4%, 6%, 8% and 10% of hydroxypropyl distarch phosphate 1, hydroxypropyl distarch phosphate 2, hydroxypropyl distarch phosphate 3 and hydroxypropyl distarch phosphate 4 with the core material stock liquid to obtain a core material liquid;

[0084] Step 5 is to perform spheroidization, wherein hydroxypropyl distarch phosphate 1, hydroxypropyl distarch phosphate 2, hydroxypropyl distarch phosphate 3 and hydroxypropyl distarch phosphate 4 all stir the coagulation bath to keep the coagulation bath in a flowing state, and then drop the core material liquid into the coagulation bath to spheroidize it for 10 minutes to obtain primary donkey-hide gelatin bursting beads;

[0085] Step 6 is to perform encapsulation, wherein hydroxypropyl distarch phosphate 1, hydroxypropyl distarch phosphate 2, hydroxypropyl distarch phosphate 3 and hydroxypropyl distarch phosphate 4 are all placed in the encapsulation liquid, and the primary donkey-hide gelatin beads are continuously stirred and encapsulated for 12 minutes to obtain encapsulated donkey-hide gelatin beads;

[0086] Step 7 is sterilization treatment, sterilizing the encapsulated donkey-hide gelatin bursting beads, and packaging them to obtain finished donkey-hide gelatin bursting beads.

[0087] The obtained beads were placed in a 37°C incubator for storage experiments. The results were as follows: Figure 3 .

[0088] Depend on Figure 3 It can be seen that the sphericity of the popping beads prepared by Example 4 is worse when the concentration of hydroxypropyl distarch phosphate is higher (8%-10%). However, when the concentration of hydroxypropyl distarch phosphate is lower (4%), the liquid leakage of the popping bead core material is serious. On this basis, 6% hydroxypropyl distarch phosphate is preferred.

[0089] Example 5

[0090] In order to improve the leakage of donkey-hide gelatin beads and highlight the effect of calcium lactate concentration on the morphology or state, the same preparation parameters as in Example 1 were used to analyze the effect of calcium lactate concentration on the morphology or state.

[0091] Four groups of donkey-hide gelatin explosive beads were prepared, named calcium lactate 1, calcium lactate 2, calcium lactate 3 and calcium lactate 4, respectively, according to the following steps:

[0092] Step 1: prepare a coagulation bath, and dissolve calcium lactate 1, calcium lactate 2, calcium lactate 3 and calcium lactate 4 in 1% sodium alginate and water, and then defoam and set aside;

[0093] Step 2: preparing a core material liquid, dissolving 4%, 6%, 8% and 10% of calcium lactate 1, calcium lactate 2, calcium lactate 3 and calcium lactate 4 and 10% of donkey-hide gelatin in water to obtain a core material stock liquid, and mixing 6% of hydroxypropyl distarch phosphate with the core material stock liquid to obtain a core material liquid;

[0094] Step 3: preparing encapsulation solution, calcium lactate 1, calcium lactate 2, calcium lactate 3 and calcium lactate 4 are all dissolved with 3% chitosan oligosaccharide in water and set aside;

[0095] Step 4: preparing a protective solution, wherein calcium lactate 1, calcium lactate 2, calcium lactate 3 and calcium lactate 4 are all dissolved in 5% fructose syrup with water and then set aside;

[0096] Step 5 is to perform spheroidization, wherein calcium lactate 1, calcium lactate 2, calcium lactate 3 and calcium lactate 4 all stir the coagulation bath to keep the coagulation bath in a flowing state, and then drop the core material liquid into the coagulation bath to spheroidize it for 10 minutes to obtain primary donkey-hide gelatin bursting beads;

[0097] Step 6 is to perform encapsulation, wherein calcium lactate 1, calcium lactate 2, calcium lactate 3 and calcium lactate 4 are all placed in the encapsulation liquid to encapsulate the primary donkey-hide gelatin beads, and the encapsulation is continuously stirred for 12 minutes to obtain encapsulated donkey-hide gelatin beads;

[0098] Step 7 sterilization treatment, calcium lactate 1, calcium lactate 2, calcium lactate 3 and calcium lactate 4 are all sterilized to encapsulate donkey-hide gelatin bursting beads, and are packaged to obtain finished donkey-hide gelatin bursting beads.

[0099] The obtained beads were placed in a 37°C incubator for storage experiments. Figure 4

[0100] Depend on Figure 4 It can be seen that the bursting beads prepared by Example 5 have little effect on preventing the leakage of bursting beads at different concentrations of calcium lactate. When the calcium lactate content is 9%, the bursting feeling of the bursting beads is poor. On this basis, 7% calcium lactate is preferred.

[0101] Example 6

[0102] In order to improve the leakage of donkey-hide gelatin beads and highlight the effect of sodium alginate concentration on the morphology or state, the same preparation parameters as in Example 1 were used to analyze the effect of sodium alginate concentration on the morphology or state.

[0103] Five groups of donkey-hide gelatin beads were prepared, named sodium algae 1, sodium algae 2, sodium algae 3, sodium algae 4 and sodium algae 5, respectively, according to the following steps:

[0104] Step 1: preparing a coagulation bath, dissolving sodium alginate 0.7%, 1%, 1.3%, 1.5% and 1.7% in water respectively, and defoaming and setting aside for use;

[0105] Step 2: preparing a core material liquid, dissolving 10% of donkey-hide gelatin and 7% of calcium lactate in water for each of sodium alginate 1, sodium alginate 2, sodium alginate 3, sodium alginate 4 and sodium alginate 5 to obtain a core material stock solution, and mixing 6% of hydroxypropyl distarch phosphate with the core material stock solution to obtain a core material liquid;

[0106] Step 3: prepare encapsulation solution, dissolve 3% chitosan oligosaccharide in water for sodium alginate 1, sodium alginate 2, sodium alginate 3, sodium alginate 4 and sodium alginate 5 and set aside;

[0107] Step 4: preparing a protective solution, wherein sodium alginate 1, sodium alginate 2, sodium alginate 3, sodium alginate 4 and sodium alginate 5 are dissolved in 5% fructose syrup with water and then set aside;

[0108] Step 5 is to perform spheroidization, wherein sodium algae 1, sodium algae 2, sodium algae 3, sodium algae 4 and sodium algae 5 all stir the coagulation bath to keep the coagulation bath flowing, and then drop the core material liquid into the coagulation bath to spheroidize it for 10 minutes to obtain primary donkey-hide gelatin beads;

[0109] Step 6 is to perform encapsulation, wherein sodium algae 1, sodium algae 2, sodium algae 3, sodium algae 4 and sodium algae 5 are placed in the encapsulation liquid to encapsulate the primary donkey-hide gelatin beads, and the encapsulation is continuously stirred for 12 minutes to obtain encapsulated donkey-hide gelatin beads;

[0110] Step 7 sterilization treatment, seaweed sodium 1, seaweed sodium 2, seaweed sodium 3, seaweed sodium 4 and seaweed sodium 5 are all sterilized and packaged to obtain finished donkey-hide gelatin bursting beads.

[0111] The obtained beads were placed in a 37°C incubator for 20 days. Figure 5 shown.

[0112] Depend on Figure 5 It can be seen that the higher the sodium alginate concentration of the popping beads prepared in Example 6, the slower the leakage of donkey-hide gelatin in the popping beads. However, when the sodium alginate concentration is too high, the sphericity of the popping beads is worse. On this basis, 1.5% sodium alginate is preferred.

[0113] Example 7

[0114] In order to improve the leakage of donkey-hide gelatin beads and highlight the effect of chitosan oligosaccharide encapsulation on the leakage of donkey-hide gelatin, the effect of encapsulation treatment on the leakage of donkey-hide gelatin was analyzed.

[0115] Step 1: prepare a coagulation bath, dissolve 1% sodium alginate in water, and defoam for later use;

[0116] Step 2: preparing a core material liquid, dissolving 10% of donkey-hide gelatin and 7% of calcium lactate in water to obtain a core material stock liquid, and mixing 6% of hydroxypropyl distarch phosphate with the core material stock liquid to obtain a core material liquid;

[0117] Step 3: preparing encapsulation solution, dissolving 3% chitosan oligosaccharide in water and setting aside;

[0118] Step 4: Prepare protective solution by dissolving 5% fructose syrup with water for standby use;

[0119] Step 5: spheroidizing, stirring the coagulation bath, keeping the coagulation bath in a flowing state, then dropping the core material liquid into the coagulation bath, spheroidizing it for 10 minutes, and obtaining primary donkey-hide gelatin beads;

[0120] Step 6: encapsulation, placing the primary donkey-hide gelatin popping beads in the encapsulation liquid, stirring and encapsulating for 12 minutes, to obtain encapsulated donkey-hide gelatin popping beads;

The initial heating temperature is 180℃ for 30min, then the temperature is raised to 280℃ for 30min, and finally raised to 420℃ for 90min. After digestion, the protein content in donkey-hide gelatin powder and donkey-hide gelatin popping beads is determined by a fully automatic Kjeldahl nitrogen analyzer. The donkey-hide gelatin content in the popping beads is obtained by proportional conversion.

[0124] Step 9 Determination of physical properties such as blasting force:

[0125] Through TA measurement, a P / 0.5 probe (contact area of ​​126.68 mm2) was selected, the speed before the test was 1.0 mm / s, the speed during the test was 5.0 mm / s, the speed after the test was 10.0 mm / s, and the trigger force was 2.0 g.

[0126] The storage experiment was carried out on the obtained popping beads, and the results were as follows Figure 6 .

[0127] Depend on Figure 6 It can be seen that encapsulation treatment of the explosive beads can effectively prevent the leakage of donkey-hide gelatin, and after being stored at 37 degrees for 30 days, it still maintains a good amber color.

[0138] Step 8: Determination of donkey-hide gelatin content in popping beads:

[0139] Weigh about 0.9-2g of popping beads, add 10ml sulfuric acid, 0.2g copper sulfate, and 3g potassium sulfate, and digest with a graphite digester. The initial heating temperature is 180℃ for 30min, then the temperature is raised to 280℃ for 30min, and finally raised to 420℃ for 90min. After digestion, the protein content in donkey-hide gelatin powder and donkey-hide gelatin popping beads is determined by a fully automatic Kjeldahl nitrogen analyzer. The donkey-hide gelatin content in the popping beads is obtained by proportional conversion.

[0140] Step 9 Determination of physical properties such as blasting force:

[0141] Through TA measurement, a P / 0.5 probe was selected and the contact area was 126.68mm 2 , the speed before the test was 1.0mm / s, the speed during the test was 5.0mm / s, the speed after the test was 10.0mm / s, and the trigger force was 2.0g.

[0142] The obtained popping beads were subjected to storage experiment, and the control group was popping donkey-hide gelatin beads with the previous parameters. The results were as follows: Figure 6 .

[0143] It can be seen from the figure that encapsulating the popping beads can effectively prevent the leakage of donkey-hide gelatin. The popping beads prepared by Example 7, 2% chitosan oligosaccharide can effectively prevent the leakage of donkey-hide gelatin. After being stored at 37°C for days, the popping beads encapsulated with 2% chitosan oligosaccharide have the highest donkey-hide gelatin content. On this basis, 2% chitosan oligosaccharide is preferred.

[0144] Example 9

[0145] In order to improve the leakage of donkey-hide gelatin explosive beads and highlight the effect of encapsulation time on the leakage of donkey-hide gelatin, the same preparation parameters as in Example 7 were used to analyze the effect of encapsulation time on the leakage of donkey-hide gelatin.

[0146] Step 1: prepare a coagulation bath, dissolve 1% sodium alginate in water, and defoam for later use;

[0147] Step 2: preparing a core material liquid, dissolving 10% of donkey-hide gelatin and 7% of calcium lactate in water to obtain a core material stock liquid, and mixing 6% of hydroxypropyl distarch phosphate with the core material stock liquid to obtain a core material liquid;

[0148] Step 3: preparing encapsulation solution, dissolving 3% chitosan oligosaccharide in water and setting aside;

[0149] Step 4: Prepare a protective solution by dissolving 5% fructose syrup with water and setting aside for use;

[0150] Step 5: spheroidizing, stirring the coagulation bath, keeping the coagulation bath in a flowing state, then dropping the core material liquid into the coagulation bath, spheroidizing it for 10 minutes, and obtaining primary donkey-hide gelatin beads;

[0151] Step 6 is to perform encapsulation, placing the primary donkey-hide gelatin beads in the encapsulation liquid, stirring continuously and encapsulating for 5 minutes, 10 minutes, 15 minutes and 20 minutes respectively, to obtain the corresponding encapsulated donkey-hide gelatin beads;

[0152] Step 7 sterilization treatment, the encapsulated donkey-hide gelatin bursting beads are sterilized and packaged to obtain finished donkey-hide gelatin bursting beads.

[0153] Step 8: Determination of donkey-hide gelatin content in popping beads:

[0154] Weigh about 0.9-2g of popping beads, add 10ml sulfuric acid, 0.2g copper sulfate, and 3g potassium sulfate, and digest with a graphite digester. The initial heating temperature is 180℃ for 30min, then the temperature is raised to 280℃ for 30min, and finally raised to 420℃ for 90min. After digestion, the protein content in donkey-hide gelatin powder and donkey-hide gelatin popping beads is determined by a fully automatic Kjeldahl nitrogen analyzer. The donkey-hide gelatin content in the popping beads is obtained by proportional conversion.

[0155] Step 9 Determination of physical properties such as blasting force:

[0156] Through TA measurement, a P / 0.5 probe (contact area of ​​126.68 mm2) was selected, the speed before the test was 1.0 mm / s, the speed during the test was 5.0 mm / s, the speed after the test was 10.0 mm / s, and the trigger force was 2.0 g.

[0157] The obtained explosive beads were subjected to storage experiments and blasting force tests. The results are as follows: Figure 7 and Fig.10 .

[0158] Depend on Figure 7 It can be seen that different encapsulation time has no obvious difference on the color of popping beads. Fig.10 It can be seen that when the encapsulation time is ≥10 min, the leakage of donkey-hide gelatin is significantly reduced. On this basis, the encapsulation time of 10 min is preferred.

[0159] Example 10

[0160] In order to improve the leakage of donkey-hide gelatin beads and highlight the effect of the amount of donkey-hide gelatin added on the leakage of donkey-hide gelatin, the same preparation parameters as in Example 7 were used to analyze the effect of the amount of donkey-hide gelatin added on the leakage of donkey-hide gelatin.

[0161] Step 1: prepare a coagulation bath, dissolve 1% sodium alginate in water, and defoam for later use;

[0162] Step 2: preparing a core material liquid, dissolving 10%, 14%, 16% and 20% of donkey-hide gelatin and 7% of calcium lactate in water to obtain a core material stock liquid, and mixing 6% of hydroxypropyl distarch phosphate with the core material stock liquid to obtain a core material liquid;

[0163] Step 3: preparing encapsulation solution, dissolving 3% chitosan oligosaccharide in water and setting aside;

[0164] Step 4: Prepare a protective solution by dissolving 5% fructose syrup with water and setting aside for use;

[0165] Step 5: spheroidizing, stirring the coagulation bath, keeping the coagulation bath in a flowing state, then dropping the core material liquid into the coagulation bath, spheroidizing it for 10 minutes, and obtaining primary donkey-hide gelatin beads;

[0166] Step 6: encapsulation, placing the primary donkey-hide gelatin popping beads in the encapsulation liquid, stirring and encapsulating for 12 minutes, to obtain encapsulated donkey-hide gelatin popping beads;

[0167] Step 7 sterilization treatment, the encapsulated donkey-hide gelatin bursting beads are sterilized and packaged to obtain finished donkey-hide gelatin bursting beads.

[0168] Step 8: Determination of donkey-hide gelatin content in popping beads:

[0169] Weigh about 0.9-2g of popping beads, add 10ml sulfuric acid, 0.2g copper sulfate, and 3g potassium sulfate, and digest with a graphite digester. The initial heating temperature is 180℃ for 30min, then the temperature is raised to 280℃ for 30min, and finally raised to 420℃ for 90min. After digestion, the protein content in donkey-hide gelatin powder and donkey-hide gelatin popping beads is determined by a fully automatic Kjeldahl nitrogen analyzer. The donkey-hide gelatin content in the popping beads is obtained by proportional conversion.

[0170] Step 9 Determination of physical properties such as blasting force:

[0171] Through TA measurement, a P / 0.5 probe (contact area of ​​126.68 mm2) was selected, the speed before the test was 1.0 mm / s, the speed during the test was 5.0 mm / s, the speed after the test was 10.0 mm / s, and the trigger force was 2.0 g.

[0172] The obtained explosive beads were subjected to storage experiments and blasting force tests. The results are as follows: Figure 8 and Fig.11 .

[0173] Depend on Figure 8 It can be seen that the higher the amount of donkey-hide gelatin added, the darker the color of the popping beads, but the color difference of the popping beads with 20% donkey-hide gelatin is relatively large. Fig.11 It can be seen that the higher the amount of donkey-hide gelatin added, the higher the donkey-hide gelatin content in the popping beads, but the popping force of 20% donkey-hide gelatin popping beads is the lowest. On this basis, 14% is preferred.

[0174] From this we can conclude that:

[0175] Optimization of the raw material ratio: By adjusting the concentration of donkey-hide gelatin, hydroxypropyl distarch phosphate, calcium lactate and sodium alginate, the physical properties and stability of the popping beads can be significantly affected. The optimal ratio of each raw material is 14% donkey-hide gelatin, 6% hydroxypropyl distarch phosphate, 7% calcium lactate and 1.5% sodium alginate.

[0176] Importance of encapsulation: Chitosan oligosaccharide as an encapsulation liquid, especially at a concentration of 2%, can effectively prevent the leakage of donkey-hide gelatin. At the same time, the encapsulation time of at least 10 minutes is the key to reducing the leakage of donkey-hide gelatin.

[0177] Influence of spheroidization process: Spheroidization time has a significant effect on the morphology of the bursting beads. A spheroidization time of 10 minutes helps to form uniform bursting beads.

[0178] Results of storage experiments: Through storage experiments at 37°C, we found that the optimized formula can maintain the amber color of the beads and reduce the leakage of donkey-hide gelatin, thereby improving the stability of the product.

[0179] Determination of physical properties: The bursting force test showed that too high a gelatin content would reduce the bursting force of the popping beads, so the gelatin content needed to be balanced to maintain the best taste of the popping beads.
