Abstract
Description
Technical Field
[0001] This invention relates to the field of infant and toddler cereal puffed snack processing technology, and in particular to an infant and toddler two-color extruded puffed snack product and its manufacturing method. Background Technology
[0002] Extruded and puffed snacks for infants and toddlers (such as puffs and cereal bars) are finger foods for infants and toddlers. They require pure raw materials that are low in sodium and sugar, and a loose texture after puffing that can slowly dissolve in saliva to reduce the risk of choking. The mainstream processing equipment in the industry is a twin-screw extruder. The production process includes key steps such as raw material acceptance, material cleaning and disinfection, ingredient grinding, mixing, extrusion and puffing, seasoning before or after baking, baking, metal detection, turnover, inner packaging material disinfection, packaging, and warehousing and transportation. Extrusion and puffing and metal detection are CCP critical control points.
[0003] Existing twin-screw extruders have only one extrusion chamber, allowing only one set of ingredients to be fed in for cooking, melting, and extrusion. Therefore, they can only produce single-color puffs and cereal bars, and cannot achieve a two-color structure within a single product. Currently, there are three main solutions for achieving "two-color" infant puffed snacks on the market: Option 1: Produce two different colors of single-color puffed granules. Then, use an octagonal barrel to physically mix the two colors of single-color puffed granules and pack them into the same bag. That is, each bag contains two colors of puffed granules, but each individual product is still a single color. It is a simple mixing and assembly of finished granules, not a single granule with two colors.
[0004] Option 2: Extrusion puffing produces a single-color blank. Before or after baking, coconut oil and fruit juice are sprayed by atomization, and then fruit and vegetable powder and seasoning powder are sprinkled on the surface for coating and coloring. The color only adheres to the outer surface of the puffed blank, and the substrate itself remains single-color. That is, the appearance of two colors is achieved by relying on the later seasoning and coating, rather than the extrusion molding itself having two colors.
[0005] Option 3: Some in the industry have attempted to use two independent twin-screw extruders with a composite die head. However, this approach requires two complete extrusion units, resulting in high equipment investment. The pressure and flow rate of the two units are difficult to synchronize, making cross-contamination and color mixing highly likely during production, leading to poor product stability. This approach has not been practically applied to the large-scale mass production of infant puffed snacks. Furthermore, existing processes lack comprehensive end-to-end control for two-color extruded products. Subsequent processes such as baking, handling, metal detection, and packaging sterilization of the two-color extruded preforms all follow the single-color product process, without any process adaptation for the two-color preforms.
[0006] In summary, there are currently no truly single-piece, two-color extruded puffed snack products for infants and toddlers on the market, nor are there corresponding manufacturing methods. Therefore, it is necessary to provide an extruded puffed snack product for infants and toddlers with two colors and its manufacturing method, which can, on the one hand, produce extruded puffed snack products for infants and toddlers with one piece of material and two colors (i.e., extruded puffed snack products for infants and toddlers with two colors), and on the other hand, realize the large-scale mass production of extruded puffed snacks for infants and toddlers with two colors. Summary of the Invention
[0007] The purpose of this invention is to provide a two-color extruded puffed snack product for infants and young children and its manufacturing method. The specific technical solution is as follows: In a first aspect, the present invention provides a method for manufacturing a two-color extruded puffed snack product for infants and young children, comprising: Step S1: The mixed A group of colored materials is fed into the first extrusion chamber; the screw speed of the first extrusion chamber is controlled to be 175~180 r / min, the discharge speed is 8~16 kg / min, and the first segmented temperature control heating treatment is adopted in the first extrusion chamber. The mixed B-group uncolored material is fed into the second extrusion chamber; the screw speed of the second extrusion chamber is controlled at 175~180r / min and the discharge speed is 8~16kg / min, and the second segmented temperature control heating treatment is adopted in the second extrusion chamber; The colored material A, which has been gelatinized in the first extrusion chamber, and the uncolored material B, which has been gelatinized in the second extrusion chamber, are extruded and expanded by a composite two-color die head to obtain a two-color expanded green blank. The colored materials in Group A include the following raw material components in parts by weight: 55-75 parts rice flour, 5-15 parts fruit and vegetable powder, 10-25 parts edible corn starch, 0.9-1.1 parts calcium carbonate, and 0.5-0.6 parts vitamin B1. The unbleached material in Group B comprises the following raw material components in parts by weight: 60-80 parts rice flour, 15-30 parts edible corn starch, 0.9-1.1 parts calcium carbonate, and 0.5-0.6 parts vitamin B1; Step S2: The two-color puffed raw material is baked and post-processed to obtain a two-color extruded puffed snack product for infants and young children.
[0008] Optionally, the temperature of the pre-cooking section in the first segmented temperature-controlled heating treatment is 85~110℃, the temperature of the melting and shearing section is 120~145℃, and the temperature of the die head section is 130~150℃.
[0009] Optionally, the second segmented temperature-controlled heating treatment uses a pre-cooking section temperature of 85~110℃, a melting and shearing section temperature of 120~145℃, and a die head section temperature of 130~150℃.
[0010] Optionally, the fruit and vegetable powder is a sieve material that has passed through an 80-100 mesh sieve; The fruit and vegetable powder includes at least one of beetroot powder, pumpkin powder, and spinach powder.
[0011] Optionally, the method for producing the infant two-color extruded puffed snack product further includes adding water to the mixed A group of colored materials to adjust the moisture content to 14%~17%; and adding water to the mixed B group of uncolored materials to adjust the moisture content to 14%~17%.
[0012] Optionally, the baking process uses a baking temperature of 80~100℃ and a baking time of 23~27min, and controls the moisture content of the finished product after baking to be 3%~6%.
[0013] Optionally, the method for producing the two-color extruded puffed snack product for infants and young children further includes a seasoning process; the seasoning process is performed before the baking process or between the baking process and the post-processing.
[0014] Optionally, the post-processing includes metal detection, turnover, sterilization of inner packaging materials, packaging, net weight detection, and warehousing.
[0015] In a second aspect, the present invention provides a two-color extruded puffed snack product for infants and young children, which is produced by the aforementioned method for producing two-color extruded puffed snack products for infants and young children.
[0016] Optionally, the infant two-color extruded puffed snack products include two-color puffs, two-color cereal bars, and two-color rings.
[0017] The application of the technical solution of the present invention has at least the following beneficial effects: (1) The present invention provides a method for producing a two-color extruded puffed snack product for infants and young children, which on the one hand can produce a single-piece, two-color extruded puffed snack product for infants and young children (i.e., a two-color extruded puffed snack product for infants and young children), and on the other hand can realize the large-scale mass production of two-color extruded puffed snacks for infants and young children. Specifically: In terms of the manufacturing method, this invention adopts step S1, in which the mixed A-group colored material and the mixed B-group uncolored material are separately mixed, conveyed, and cured through the first extrusion chamber and the second extrusion chamber, respectively, to fundamentally avoid color mixing before extrusion. The screw speed and discharge speed used in the first and second extrusion chambers can be independently adjusted according to actual conditions. Under the first and second segmented temperature-controlled heating treatments, the A-group colored material gelatinized in the first extrusion chamber and the B-group uncolored material gelatinized in the second extrusion chamber are both high-temperature, high-pressure viscous colloids when flowing to the composite two-color die head. The material contact interface can adhere to each other by molecular forces, forming a continuous composite material flow, ensuring that the subsequently produced two-color puffed preform is a complete whole and will not easily fall apart; in addition, the two materials only meet at a very short distance from the discharge port of the composite two-color die head, and are immediately extruded from the die hole. The two materials mix for a very short time, and the pressure is released at the moment of extrusion, causing puffing. The materials cool and solidify rapidly, directly fixing the clear two-color boundary to obtain a two-color puffed preform; furthermore, in step S2, the two-color puffed preform is baked and post-processed to obtain a two-color extruded puffed snack product for infants and young children.
[0018] In terms of ingredients, Group A, the colored material, uses rice flour as the base ingredient, combined with fruit and vegetable powders to achieve coloring of the raw materials themselves, without adding artificial pigments, meeting the requirements of GB10769-2025 for infant food ingredients; edible corn starch is used to adjust the gelatinization effect and viscosity of the material. Group B, the uncolored material, uses rice flour combined with edible corn starch, which facilitates the formation of a creamy white molten material flow under the second-stage temperature-controlled heating process. The two formulas are combined to ensure that the viscosity and flowability of the two materials are as similar as possible after extrusion and melting. On the one hand, the two materials will not interfere with each other under high pressure, and the boundary between the two colors remains clear. On the other hand, the two materials can be firmly bonded when they meet at the composite two-color die head, so that the produced two-color puffed green body will not separate and crack.
[0019] Therefore, the present invention adopts steps S1 to S2 with controllable parameters, and combined with the specific ingredient composition in step S1, it can not only produce single-piece, two-color extruded puffed snack products for infants and young children (i.e., two-color extruded puffed snack products for infants and young children), but also realize the large-scale mass production of two-color extruded puffed snacks for infants and young children.
[0020] (2) The present invention strictly controls the moisture content of the colored material of group A to 14%~17% and the moisture content of the uncolored material of group B to 14%~17%, and combines the first segmented temperature control heating treatment and the second segmented temperature control heating treatment, so that the starch raw materials in the colored material of group A and the uncolored material of group B form molten materials with similar viscosity after being heated, which makes it easier to obtain a two-color puffed green body after extrusion and puffing in the composite two-color die head. The two-color boundary is clear, the occurrence rate of color mixing is significantly reduced, and the yield rate is increased by more than 15%. Among them, the formation of molten materials with similar viscosity can prevent the material on one side from rushing into the material on the other side under the high pressure environment of extrusion and puffing in the composite two-color die head, causing the color boundary to be blurred.
[0021] (3) The present invention provides a two-color extruded puffed snack product for infants and young children, which can achieve one-piece two-color molding of a single embryo with clear two-color boundaries, unlike existing two-color foods that are coated with powder and colored later and mixed with different colored finished products; at the same time, the raw materials of the product are compatible with the standards for infant and young children's consumption, no artificial pigments are added, the texture is loose and easy to dissolve, and the forms of puffed snack products for infants and young children are enriched. In addition, the two-color extruded puffed snack product for infants and young children provided by the present invention can achieve diversified two-color selection by changing the fruit and vegetable powder; it can also achieve diversified product shape selection such as two-color puffs, two-color cereal bars and two-color rings by changing the composite two-color mold head.
