Description

Technical Field

[0001] The present invention relates to the technical field of food popping bead preparation, in particular to a plant-based instant popping bead and a preparation method thereof. Background Art

[0002] Bursting beads are seamless pellets made by wrapping the fluid contents with a high-molecular hydrophilic material and then drying them. They are called bursting beads because of the popping sound produced during the bursting process under pressure. Most of the plant-based bursting beads commonly used in food currently release their contents by biting, and the rubber can only be swallowed or discarded. The wall materials are usually heat-soluble colloids such as agar, carrageenan, and gellan gum. These colloids have a very obvious characteristic, that is, they can be dissolved into liquid solutions at high temperatures and solidified into jelly at low temperatures. The resulting bursting beads are also affected by the properties of the colloid itself and will not dissolve in water at room temperature. They cannot quickly disintegrate and turn into slag during consumption, and cannot be used in some low-temperature disintegration and release fields.

[0003] In the prior art, edible gelatin is often used as the main wall material to achieve rapid disintegration in the human mouth, such as in the methods described in patents CN115413778A and CN118452501A. However, gelatin also has drawbacks, such as its inability to disintegrate quickly at room temperature or in cold water, and its use is also subject to numerous limitations. Plant-based popping beads, such as those described in patent CN118512037A, use sodium alginate and carrageenan as the main wall materials, forming a stable film through ionic crosslinking that is insoluble in water at room temperature.

[0004] In current droplet technology, processes using plant-based materials require hot-melt cold-molding materials to ensure the strength of the wet droplets for easy drying. Therefore, they cannot disintegrate and dissolve quickly when consumed or placed in cold water. In response to this, the present application proposes a plant-based instant droplet and its preparation method. Summary of the Invention

[0005] The purpose of the present invention is to provide a plant-based instant popping bead and a preparation method thereof to solve the problems in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: In a first aspect, the present invention provides a method for preparing plant-based instant popping beads, comprising the following steps:

[0007] Step (1), preparing core material;

[0008] Step (2): Prepare the wall material to wrap the core material:

[0009] Use plant-based polymer materials that are soluble at room temperature, mix them, disperse them in hot water, and make a high-concentration, low-viscosity wall material solution;

[0010] Step (3), phase transformation:

[0011] A double-layer co-directional hollow shaft is used to produce the popping beads. The circulating oil adopts multi-stage temperature control technology to make its temperature change periodically from 20℃→-10℃→20℃. The liquid droplets are cooled step by step from 80℃ to -10℃ in the cooling circulating oil, and then turned into solid popping beads and filtered out. After the popping beads are filtered out, the temperature is raised to 20℃ for reflux.

[0012] Step (4), low temperature dehydration:

[0013] After phase transformation, the popping beads enter the freeze drying equipment for dehydration and drying, and the water content is controlled at 10-15%;

[0014] Step (5), densification treatment:

[0015] After dehydration, the popping beads enter the humidity-controlled drum for critical rehydration welding, so that a dense continuous film is formed on the surface of the capsule shell, achieving good coating effect and mechanical strength;

[0016] Step (6), disintegration coating:

[0017] After the density treatment is completed, the popping beads enter the coating pot for surface density disintegration treatment, so that a large area of super hydrophilic structure is formed on the surface of the popping beads the moment they enter the water.

[0018] Preferably, the moisture-controlled welding in step (5) requires intermittent induced draft with a humidity of 60-100% to perform critical melting treatment to form a dense continuous layer.

[0019] Preferably, the specific steps of step (6) are as follows:

[0020] After critical welding is completed, high expansion alginate is coated once to evenly coat the surface of the popping beads with a layer of high expansion alginate powder, with a coating weight ratio of 2-5%;

[0021] Use baking soda and dextrin for secondary coating, with a coating weight ratio of 5-10%;

[0022] After the two coatings are completed, the popping beads are subjected to three coatings and hardening treatments using 80% maltose syrup, with a coating weight ratio of 1-3%.

[0023] Preferably, the core material is liquid oil, and the wall material wrapping the core material is hydrophilic plant polysaccharide.

[0024] Preferably, the core material includes but is not limited to one or more of algae oil, MCT, and soybean oil; the wall material includes but is not limited to one or more of gum arabic, pullulan, and guar gum.

[0025] Preferably, the phase-changing molding circulating oil is low-melting-point grease.

[0026] Preferably, the low-temperature dehydration in step (4) adopts low-temperature freeze-drying technology to form the wall material into a supportable frame structure.

[0027] Preferably, the densification treatment in step (5) uses critical welding technology to transform the porous framework structure into a dense continuous film.

[0028] The second aspect of the present invention provides a plant-based instant popping bead, which is prepared by the method described in the first aspect of the present invention.

[0029] The third aspect of the present invention provides an application of the plant-based instant popping beads described in the second aspect of the present invention, and the plant-based instant popping beads can be used in the field of food or health care products.

[0030] The present invention has at least the following beneficial effects:

[0031] The present invention provides a plant-based instant popping bead and a preparation method thereof. Through humidity control and critical welding, a dense and continuous film is formed on the surface of the popping bead wall material. Through disintegrating coating, a super-hydrophilic transition layer can be quickly formed on the surface of the popping bead after entering water, thereby accelerating the water absorption of the popping bead skin and enabling the popping bead to quickly disintegrate and release in water at room temperature or after being taken into the mouth.
