[0041] Gel-ball
[0042] The term “gel-ball” as used herein relates to a rounded object that is solid and soft. The gel-ball is elastic with a gelatinous or slippery texture. The gel-ball has an elastic structure. The gel-ball disclosed herein is heat-resistant as well as cold-resistant.
[0043] The term “elastic” as used herein relates to a property of a gel-ball, outer skin, and / or core to deform or elongate under an applied external force, and to return substantially to its original shape or length when the external force is removed. It will be understood that the applied external force is not sufficient to destroy the gel-ball but is only sufficient to deform or elongate the gel-ball.
[0044] The term “chewy” as used herein relates to a property of a gel-ball to be masticable, e.g., deform or elongate under an applied external force in the jaw of a consumer.
[0045] The present invention relates to a rounded object preferably a gel-ball suitable to be added to food, feed, beverage, cosmetic or pharmaceutical products. The gel-ball comprises a core and an outer skin at least partially enclosing the core. The core comprises a core gel network, preferably the core gel network comprises a humectant and a gelling agent. The outer skin comprises a skin gel network comprising calcium alginate. The core and the outer skin lie in two different layers that are separable from each other. The outer skin may be peelable from the core of the gel-ball. In one aspect, the core gel network and the skin gel network do not intermingle with each other at the junction between the core and the outer skin.
[0046] In one aspect, the rounded object according to the present invention is a gel-ball. In one aspect, the gel-ball is in grape-like shape, such as round-shaped, oblate-shaped, oblong-shaped, oval-shaped, heart-shaped, egg-shaped, obovate-shaped, etc. In one aspect, the rounded object preferably a gel-ball has a grape-like two-layer structure, i.e., an outer skin and a core. For example, FIG. 1 shows a gel ball 100 that includes an outer skin 102 and a core 104. In one aspect, both the outer skin and the core are solid (e.g. in a non-flowable state at room temperature) . In one aspect, the outer skin and the core have different textures, for example, like the skin and pulp of a grape having different textures. In one aspect, the gel-ball is elastic. In one aspect, both the outer skin and the core are elastic. The elasticity of the outer skin and the core may be different. The elasticity of the outer skin and the core may be the same. In one aspect, elasticity refers to the property of a gel-ball, outer skin, or core to deform or elongate under an applied external force, and to return substantially to its original shape or length when the external force is removed.
[0047] In one aspect, the outer skin comprises a skin gel network comprising calcium alginate. In one aspect, the texture of the outer skin comprising the skin gel network comprising calcium alginate is different from the texture of the core comprising a core gel network comprising a humectant and a gelling agent. In one aspect, the core and the outer skin lie in two different or distinct layers that are separable and / or peelable from each other. By distinct, it is meant that the core and the outer skin are not intermingled but layered as separate structural components. “Separable from each other” means that the outer skin and the core can be separated or means that the outer skin can be peeled off from the core, like the skin and pulp of a grape, and the outer skin and the core are not adhered after separation / peeling. Preferably, the core of the gel-ball is not damaged or disintegrated when the outer skin is separated from the core of the gel-ball.
[0048] In one aspect, the rounded object, preferably a gel-ball according to the present invention is heat-resistant, for example, the rounded object preferably a gel-ball is resistant to a temperature of about 95-121℃. In one aspect, the gel-ball maintains integrity when exposed to a temperature of 95-121℃. In one aspect, the gel-ball maintains integrity when exposed to a temperature of 95-121℃ for 5 to 15 minutes. In one aspect, heat-resistance refers to the ability to substantially maintain its original properties, including shape, texture, integrity, elasticity, and / or mouthfeel, etc. under heating conditions, e.g. at a temperature of 95-121℃. In one aspect, the rounded object preferably a gel-ball is not heat resistant as it is used in food and / or beverages that do not need to go through heat treatment, such as iced Boba tea. In one aspect, the rounded object preferably a gel-ball is cold resistant and can be used in cold food and / or beverages. In one aspect, the rounded object preferably a gel-ball is both heat resistant and cold resistant.
[0049] “Maintaining integrity” described herein means that the overall structure of the rounded object, preferably a gel-ball remains the same or substantially the same before and after it is exposed to external force and / or conditions, e.g., heat or frozen. For example, after being heated, the outer skin of the gel-ball still encloses the core, and the outer skin and the core remain in two different layers. For example, after being frozen, the outer skin of the gel-ball still encloses the core, and the outer skin and the core remain in two different layers.
[0050] In one aspect, the rounded object, preferably a gel-ball according to the present invention is cold-resistant. The term “cold resistant” means that the gel-balls exhibit chewy and / or elastic properties at cold temperatures, e.g. below 0℃, or from 0℃ to -50℃, or from -10 ℃ to -20℃, or from 0 ℃ to -10℃, or from -12℃ to -18℃. In one aspect, the frozen gel balls do not have to be thawed prior to use in frozen application. The gel balls are consumed in the frozen food without thawing and are still substantially elastic and chewy at cold temperatures.
[0051] The cold-resistant, double-layered gel-balls of the present invention can be used in frozen applications. The inventors also discovered that all alginate gel-balls are cold resistant and thus can be used in frozen applications.
[0052] In one aspect, the rounded object preferably a gel-ball according to the present invention is substantially spherical such as round-shaped, oblate-shaped, oblong-shaped, oval-shaped, heart-shaped, egg-shaped, obovate-shaped, etc.
[0053] In one aspect, the outer skin of the rounded object preferably a gel-ball according to the present invention completely encloses the core. In one aspect, “completely encloses” refers to that the outer skin completely covers, wraps or seals the core (i.e., 100%enclosed) . In another aspect, the outer skin of the rounded object preferably a gel-ball according to the present invention at least partially encloses the core. In another aspect, “at least partially encloses” means that the outer skin encloses at least about 10%, about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, about 90%, about 95%, about 98%, or about 99%of the core.

In addition, it can be seen that both the outer skin 312 and the core 314 of the gel-ball 310 maintain in solid form after sterilization.
[0174] It should be noted that the deformation of the two-layered gel-ball 310 after sterilization was due to the pressure change caused from the high-temperature sterilization process (121℃) to cooling stage. Lots of small bubbles exist in the liquid mixture due to lack of exhaust process in the laboratory samples, and thus the outer skin cannot be completely restored to its original size and shape due to the pressure change after going through the sterilization (which led to expansion) and cooling stage. This Example aims to indicate the two-layered structure of the gel-ball 310 and thus no exhaust process was adopted, leading to the deformation. In fact, in the actual manufacturing process, the deformation may be addressed by using e.g. a vacuum exhaust process.
[0175] The appearance of the gel-ball of Example 3 after sterilization under 121℃ for 15 minutes is shown in FIG. 9. The gel-ball 410 still has an outer skin 412 and a core 414 after sterilization and the integrity of the gel-ball 410 is maintained.
[0176] The appearance of the gel-ball of the Comparative Example 2 after sterilization under 121℃ for 15 minutes is shown in FIG. 10. Although the gel-ball 510 maintained a ball shape structure after sterilization, it does not have a two-layer structure.
[0177] The appearance of the gel-ball of Comparative Example 3 before and after sterilization under 121℃ for 15 minutes is shown in FIGS. 11A and 11B, respectively. It can be observed from FIG. 11A that the surface of the gel-ball 606 of the Comparative Example 3 is rough with frosted appearance. FIG. 11B shows that the gel-ball 610 of the Comparative Example 3 completely collapsed after sterilization and it transformed from a ball-shaped solid to an amorphous slurry after sterilization under 121℃ for 15 minutes.
[0178] Example 4
[0179] Preparation of frozen gel-balls 1-3
[0180] The gel-balls of Examples 1-3 are placed in a freezer until they are frozen to obtain frozen gel-balls 1-3.
[0181] Example 5
[0182] Preparation of frozen gel-balls 4-6.
[0183] A first mixture was prepared according to the ingredients in Table 10. The first mixture was heated to the indicated temperature for the indicated period in Table 10. The powder ingredients are mixed first and then they are added into liquid ingredients (water and syrup) . The mixture is blended and heated to a temperature around 90-95℃.
[0184] Table 10
[0185] A second mixture was prepared according to the ingredients in Table 11. The second mixture was heated to the indicated temperature in Table 11. Sodium alginate and optional sugar are added into water for blending, and they are heated to the setting temperature at 60℃.
[0186] Table 11
[0187] The first mixture is added drop by drop to the second mixture and they are maintained for 5 minutes as shown in Table 12.
[0188] Table 12
[0189] As described above, the gel-balls are then filtered and soaked in sugar water solution such as the third mixture. The gel-balls are sterilized for 15 minutes under a temperature of 121℃. The gel-balls are placed in a freezer until they are frozen to obtain frozen gel-balls.
[0190] Example 6
[0191] Appearance of frozen gel-balls 4-6 is described in Table 13. The gel-ball was analyzed by a pressure test conducted on a Texture Analyser. The Texture Analyser is used in a compression / force test mode with a Pre-test speed of 0.5mm / second. The deformation distance of a frozen gel-ball at a set force of 80Newtons was determined. Pressure tests under a force of 80N are conducted onto the frozen gel-balls to determine the deformation distance / extent that the frozen gel-balls can take under the external force.
[0192] Tapioca balls are purchased commercially from the market. Frozen gel-balls 4-6 and tapioca balls have similar sizes.
[0193] Table 13
[0194] Frozen gel-balls 4-6 before and after frozen are shown in FIGS. 12A-12F, respectively. Tapioca balls before and after frozen are shown in FIGS. 12G and 12H, respectively. The diameters of frozen gel-balls 4-6 and tapioca balls are around 12mm.
[0195] Frozen gel-balls 1-3 are cold resistant (FIGS. not shown) . Frozen gel-balls 4-6 are cold resistant, but tapioca balls are not. Frozen gel-balls 4-6 have a longer deformation distance than frozen tapioca balls when the pressure tests are conducted onto the balls, which indicates that frozen gel-balls 4-6 are more chewy and elastic than frozen tapioca balls.
[0196] The pressure tests demonstrate the elasticity of the frozen gel-balls even at cold temperatures. The appearance of the frozen gel-balls is different in the cold temperatures than the gel-balls before frozen as they are no longer transparent but are cloudy / milky in appearance. In contrast, the frozen tapioca-based gel balls are not chewy as the frozen gel-balls of the present invention when used in frozen application and do not have the elasticity and chewiness of gel balls that are cold-resistant. The appearance of the frozen tapioca gel balls is cloudy / milky similar to the frozen gel balls but the texture and elasticity are different.
[0197] Thus, frozen gel-balls 1-6 are more suitable to being used in frozen applications such as cold food or cold beverages than frozen tapioca balls.
