Abstract
Description
Technical Field
[0001] This invention patent relates to a lotus root starch pearl tapioca pearl and its manufacturing method. Background Technology
[0002] Lotus root starch, a traditional Chinese medicine, is a starch processed from the rhizome of the lotus plant (Nelumbo nucifera), a member of the Nymphaeaceae family. Distributed throughout China, it is also known as lotus root starch. It is sweet and salty in taste, and neutral in nature, entering the spleen, liver, and kidney meridians. It has the effects of nourishing blood, stopping bleeding, regulating the middle jiao (digestive system), and stimulating appetite. It is mainly used to treat weakness and blood loss, diarrhea, and poor appetite. Modern research shows that lotus root contains active substances such as polysaccharides and polyphenols, which can enhance antioxidant capacity, lower blood lipids, and alleviate intestinal inflammation. Its antioxidant and anti-inflammatory effects are significantly enhanced after cooking.
[0003] Tapioca pearls are a type of snack food made primarily from tapioca starch. They have a unique chewy texture and transparency, and are a classic topping in milk tea, enjoying widespread popularity among consumers.
[0004] Traditional tapioca pearls and ready-to-eat tapioca pearls are the two most commonly used types in tea shops. Traditional tapioca pearls require a long boiling time. Ready-to-eat tapioca pearls only need to be reheated briefly, making them convenient and quick, but their texture is harder compared to traditional tapioca pearls. Both existing types of tapioca pearls have short storage times after boiling or reheating, their texture deteriorates quickly, and neither can be repeatedly frozen and thawed.
[0005] Lotus root contains 80% water and 11% starch. Starch is the most abundant nutrient in lotus root, and the starch extracted from lotus root is called lotus root starch. The average amylose content in lotus root starch is 16.9%, and the average amylopectin content is 83.1%. Compared to the average 20%-30% amylose content in tapioca starch, pure lotus root starch has a significantly lower amylose content, resulting in a softer, smoother texture for tapioca pearls.
[0006] Chinese Patent Publication No. CN 112956628 A discloses a tapioca pearl based on triacinol, its preparation method, and its application. The composition and weight parts are as follows: triacinol 0.5-1.0 parts, tapioca starch 0-18 parts, konjac flour 0-6 parts, Jerusalem artichoke flour 0-7 parts, dietary fiber powder 0-12 parts, calcium chloride 0-0.3 parts, sweetener 0-0.1 parts, and edible flavoring 0-0.02 parts. The wet tapioca pearl production method provided by this invention is simpler and has higher preparation efficiency. Furthermore, the tapioca pearls made from triacinol, dietary fiber powder, konjac flour, and Jerusalem artichoke flour as main raw materials provide a prolonged feeling of fullness while being low in calories and glycemic index, making them a healthy and low-calorie tapioca pearl product.
[0007] Chinese Patent Publication No. CN 117378754 A discloses an anti-aging tapioca pearl and its preparation method. The anti-aging tapioca pearl of this invention comprises the following components: 90-120 parts of damaged tapioca starch, 30-35 parts of trehalose, 6-8 parts of starch acetate, 0.2-0.4 parts of sodium alginate, and 45-60 parts of water. This invention first uses a mechanical activation method to prepare damaged starch, which disrupts the starch's crystalline structure and reduces the starch aging rate. Then, the damaged starch is mixed with food additives to effectively enhance the water retention capacity of the tapioca pearl, encapsulating more water molecules and thus improving its anti-aging properties. This invention improves the tapioca pearl preparation process, eliminating the need for pregelatinization or the addition of binders to prepare raw tapioca pearls. The cooked tapioca pearls exhibit excellent anti-aging properties, overcoming the shortcomings of traditional tapioca pearls, such as easy aging after cooking and short shelf life.
[0008] By comparison, this patent application is fundamentally different from the aforementioned patent publications.
[0009] Therefore, we developed an instant tapioca pearl made primarily from lotus root starch, which can be repeatedly frozen and thawed, and has a soft, chewy, and smooth texture with a crystal-clear surface, distinguishing it from the taste and appearance of traditional tapioca pearls. Summary of the Invention

Step 6: Prepare the sugar syrup. Mix the tapioca pearls and sugar syrup according to the ratio, and then fill the mixture into packaging bags. Step 7: Place the product in a -35℃~-30℃ quick-freezing chamber for 3h±0.5h to bring the core temperature of the product down to -18℃.
[0016] Furthermore, the soft filling in step 4 is a soft filling with a diameter of 3-7mm after being rolled into balls, and the diameter of the tapioca balls is 6-11mm.
[0017] Furthermore, in step 5, the hot water temperature is 80-90℃, and the scalding time is 50 seconds to 5 minutes. Then, cool in 10-18℃ water for 3-4 minutes.
[0018] Furthermore, in step 6, the ratio of tapioca pearls to sugar syrup is 60-70:30-40.
[0019] Furthermore, in step 6, the ratio of tapioca pearls to sugar syrup is 65:35.
[0020] Further, in step 1, mix the soft filling evenly, add 0-0.1 parts of edible flavoring, stir-fry at 60-65℃ for 10 minutes, remove and let cool naturally for later use.
[0021] The beneficial effects of this invention are: Using lotus root starch as the main ingredient, we offer ready-to-eat tapioca pearls that can be repeatedly frozen and thawed and have better room temperature storage stability after reheating.
[0022] The soft, smooth texture and crystal-clear appearance of lotus root starch have been introduced into the tapioca pearl category, changing and subverting the traditional taste and appearance of tapioca pearls. Attached Figure Description

Set an induction cooker to 2100W, place 3-5 bags in each pot, add cold water just enough to cover the bags, and set a timer for 6 minutes. After heating, remove and rinse with cold water to cool to room temperature, then freeze at -18℃ overnight. The next day, remove and heat in a household microwave oven (rated output power 700W-800W) for 2 minutes, then place in a container of cold water to cool. Perform sensory evaluation.
[0075] Table 1 Sensory Evaluation Table for Tapioca Pearls
[0076] Table 2 Sensory evaluation results of Examples 2-9 and comparative examples.
[0077] Table 2 shows that pure lotus root powder exhibits better resistance to repeated freeze-thaw cycles than instant lotus root powder, mainly because the starch content in instant lotus root powder is lower than that in pure lotus root powder. With increasing blanching time, the hardness and elasticity of the product decreased after repeated freeze-thaw treatment; therefore, longer blanching time is not necessarily better. Comparative Example 1, after repeated freeze-thaw pretreatment, showed significantly inferior taste and texture compared to Examples 2-9, which contained added lotus root powder.
[0078] Room temperature stability test Set the induction cooker to 2100W, place 3-5 packets per batch, add cold water until the water level just covers the packets, and set the timer for 6 minutes. After heating, remove the packets and allow them to cool naturally at room temperature. Let them sit at room temperature for 24 hours, then measure the change in diameter of the tapioca pearls. The results show that Example 2 is superior to the comparative example, with a significantly lower degree of water absorption and swelling. See details below. Figure 1-4 .
[0079] Texture analysis Test steps: 1) Pretreatment: Cut a small opening in the packaging, microwave the packaging bag together on medium-high power (700W-800W) for 2 minutes, cool it to room temperature with cold water before testing.
[0080] 2) The textural properties (hardness, elasticity, and chewiness) of the extrudate were determined using a texture analyzer (Shimadzu, EZ-X, Japan) in TPA mode. First, the thawed samples were cut into 30mm*15mm*6mm pieces (with slight modifications based on actual dimensions). Then, the samples were compressed twice using an R36 cylindrical probe with a diameter of 36 mm. The specific TPA mode parameters were set as follows: test speed 1.5mm / s, compression ratio 40%, trigger force 101.97 gf, rise distance 15mm. Each sample was measured three times, and the average value was taken.
