Description

Technical Field

[0001] The invention relates to the technical field of probiotic soft candy preparation, and in particular to a method for preparing highly active probiotic soft candy. Background Art

[0002] Probiotic gummies are candies containing probiotics, which have multiple functions such as supplementing intestinal flora, promoting digestion, and enhancing immunity. As people pay more and more attention to health and the demand for health products continues to expand, the market demand for probiotic gummies is also increasing, and it is becoming more diversified and efficient. In the future, with the development of science and technology and the continuous improvement of production technology, probiotic gummies will have a broader development prospect in the market.

[0003] The preparation of probiotic gummies is carried out according to a specific formula. Probiotics, edible gum and other auxiliary materials are added to the gummies during the cooking process of the gummies. After condensation and drying, the gummies are obtained which help regulate the balance of intestinal microecology.

[0004] The probiotic gummies currently on the market contain very low levels of active ingredients and the probiotic gummies are labeled based on the amount of live probiotics added.

[0005] Currently, the probiotic soft candies on the market are generally prepared by the traditional boiling gel method. This method usually includes steps such as high-temperature dissolution of gelatin, addition of probiotics, mixing and molding, and cooling and molding. The entire process takes a long time. However, since the high temperature environment has a significant effect on the activity of probiotics, the activity of probiotics in the final product is difficult to control. In addition, the existing preparation process is relatively complicated and has high requirements for the operating environment, which further increases the production cost and difficulty.

[0006] Disadvantages of existing technology: 1) High temperature treatment affects the activity of probiotics: High temperature steps in the preparation process will significantly reduce the activity of probiotics, greatly reducing the functionality of the product; 2) Complex process: The existing probiotic soft candy preparation process has many steps and requires strict control of temperature and time, which increases the difficulty and cost of production; 3) Poor stability: During the preparation process, due to the sensitivity of probiotics to temperature and environment, the stability of probiotics in the final product is poor, affecting its shelf life and efficacy. Summary of the invention

[0007] The purpose of the present invention is to solve the above technical problems and provide a method for preparing highly active probiotic soft candy.

[0008] In order to achieve the above technical objectives and meet the above technical requirements, the technical solution adopted by the present invention is: a highly active probiotic soft candy, including a solid premix, a mixed solution A, and a mixed solution B. The solid premix includes the following components in parts by weight: 60 to 90 parts of a first sweetener and 10 to 40 parts of gelatin powder; the mixed solution A includes the following components in parts by weight: 40 to 80 parts of a second sweetener, 10 to 60 parts of purified water, and 0.1 to 2 parts of auxiliary materials; the mixed solution B includes the following components in parts by weight: 40 to 85 parts of purified water, 10 to 40 parts of an embedding agent, and 0.1 to 20 parts of probiotics.

[0009] The sum of the above components is 100 parts.

[0010] The solid premix is ​​best selected to contain 80 parts of the first sweetener and 20 parts of gelatin powder; the first sweetener is one or more of white sugar, erythritol, maltitol, isomalt, xylitol, trehalose, and sorbitol, preferably white sugar and maltitol. The jelly strength value of edible gelatin powder ranges from 50 Bloom to 300 Bloom, preferably 180 Bloom and 220 Bloom.

[0011] The mixed liquid A is optimally composed of 73 parts of a second sweetener, 25 parts of pure water, and 2 parts of auxiliary materials, wherein the second sweetener is one or more of glucose syrup, corn syrup, maltose syrup, maltitol liquid, sorbitol liquid, white sugar, erythritol, maltitol, isomalt, xylitol, trehalose, and sorbitol; the auxiliary materials are one or more of flavors, pigments, flavoring agents, and plasticizers; the plasticizer is one or more of glycerol, sorbitol, glyceryl monooleate, propylene glycol, and polyethylene glycol, preferably glyceryl monooleate and glycerol.

[0012] The optimal selection for the mixed solution B is 5 parts of probiotics, 65 parts of purified water, and 30 parts of embedding agent. The probiotics are one or more of Bacillus, lactic acid bacteria, and Bifidobacterium, preferably Bacillus coagulans and Bacillus subtilis; the embedding agent is one or more of cyclodextrin, agar, sodium alginate, gelatin, gellan gum, and chitosan, preferably water-soluble chitosan, low-acyl gellan gum, and high-acyl gellan gum.

[0013] A method for preparing highly active probiotic soft candy comprises the following steps: Step 1: preparing a solid premix: preparing a first sweetener and gelatin powder according to weight proportions respectively, and mixing them evenly using a solid material mixing device to obtain a solid premix; Step 2, preparation of mixed solution A: prepare the second sweetener, purified water, and auxiliary materials according to weight proportions, and mix and stir them evenly using a liquid material mixing device to obtain mixed solution A; Step 3, preparation of mixed solution B: prepare purified water, embedding agent, and probiotics respectively according to weight proportions, and use a liquid material mixing device to mix evenly to obtain mixed solution B; specifically, the purified water is heated to 80° C. and then the embedding agent is added, and after the embedding agent is completely dissolved, a water-soluble embedding solution is obtained, and after the embedding solution is cooled to 40° C., the probiotics are added, and the solution is fully dispersed and embedded for later use; Step 4, preparation of probiotic soft candy: add the solid premix prepared in step 1 into the mixed solution A prepared in step 2, control the temperature at 40°C, add the mixed solution B after the solid premix is ​​completely dissolved and dispersed, ensure that the temperature of the whole process when adding the mixed solution B does not exceed 40°C, obtain the mixed solution C, and prepare the highly active probiotic soft candy by a pouring machine; Step 5: Cooling and packaging: Place the prepared soft candy in a cooling room to cool and dry, and finally package it.

[0014] The solid material mixing equipment comprises a single-arm hoist, and a mixing hopper is connected to the single-arm hoist via a connecting frame. The single-arm hoist drives the mixing hopper to rotate so that the materials are mixed evenly.

[0015] The liquid-material mixing equipment comprises a tank body, the tank body is connected to a temperature control system, a motor is arranged on the tank body, a stirring mechanism is connected to the motor output shaft, and the mixed liquid is stirred and evenly mixed and outputted through an infusion pump.

[0016] Compared with the traditional structure, the invention has the following beneficial effects: 1. Use water-soluble embedding agents to protect the activity of probiotics. Chitosan is a cationic polysaccharide. The probiotics are effectively embedded to form a carrier through the cross-linking of anionic and cationic polysaccharides in gellan gum and water-soluble chitosan, ensuring the high activity of probiotics during use; 2. Cold-soluble gelatin powder is used as the main gelling agent to prepare soft candies. Gelatin powder is fully dissolved in a low temperature environment, which can avoid the destruction of the activity of probiotics by high temperature during the preparation process, further ensuring the high activity of probiotics; 3. The process of the present invention is simple, adopts a low-temperature preparation process, and controls the temperature through a mold temperature controller. The preparation temperature does not exceed 40°C, which maximizes the activity of the probiotics and ensures the stability of the probiotics during the production process, thereby improving the shelf life and functionality of the final product.
