[0001] The present invention relates to the technical field of food, in particular to a sugar-controlled composite instant cereal powder and a preparation method thereof. Background Art

[0002] With the improvement of living standards and changes in lifestyle, modern people's dietary structure has undergone significant changes. Excessive intake of refined grains and high-sugar foods, as well as reduced physical activity, have made blood sugar problems more common, and the number of people with diabetes and high blood sugar levels is on the rise. For these people, daily dietary management is a key link in controlling blood sugar levels.

[0003] Among the many convenience foods, instant cereal powders have become the choice of many consumers due to their ease of consumption and rich nutrition. However, traditional instant cereal powders have some shortcomings in meeting the needs of blood sugar management. On the one hand, their main ingredients are mostly common grains, which are quickly broken down into glucose after entering the human body, causing a rapid increase in blood sugar and hindering stable blood sugar control. On the other hand, traditional instant cereal powders have a relatively simple nutritional composition. For example, they generally lack key nutrients such as dietary fiber that can delay carbohydrate absorption and stabilize blood sugar. This not only reduces the product's ability to regulate blood sugar, affecting the blood sugar control effect of people with blood sugar management and hindering the stable maintenance of blood sugar, but also reduces the product's nutritional value, thereby reducing the overall quality of the sugar-control compound instant cereal powder.

[0004] In view of this, there is an urgent need for a sugar-controlled composite instant cereal powder and a preparation method thereof. Summary of the Invention

Then, the rinsed germs are placed in a drying oven and dried at a temperature of 42°C-48°C to reduce the moisture content of the germs to 5%-7%. The germs are then crushed using a crusher to a fineness of 100-120 mesh. The 13 types of germs include wheat germ, pea germ, black bean germ, soybean germ, peanut germ, buckwheat germ, broad bean germ, lentil germ, climbing bean germ, mung bean germ, red bean germ, corn germ and pine willow germ; Step 2, preliminary mixing: pour black rice powder, mulberry leaf powder, kudzu root powder, and polygonatum powder into a mixer in this order and mix them. The mixer mixes at a speed of 30 r / min-40 r / min for 30 min-36 min to fully mix the four powders to form a preliminary mixed raw material; Step 3. Mixing the sugar control synergist: Keep the mixer in a continuous stirring state at a speed of 30r / min-36r / min, add the sugar control synergist to the preliminarily mixed raw materials at a speed of 1g / s-1.6g / s. After the addition is completed, adjust the stirring speed of the mixer to 40r / min-50r / min and continue mixing for 35min-40min to fully blend the sugar control synergist with other raw materials. Step 4, final mixing: Pour all 13 kinds of germs into the mixer containing the above mixed raw materials at one time, turn on the mixer to mix all the ingredients evenly, and mix at a speed of 30r / min-40r / min for 25min-35min to form the finished product of sugar-controlled composite instant cereal powder.

[0023] In the invention, the dosage of black rice flour, mulberry leaf powder, kudzu root powder, polygonatum powder, 13 kinds of germs and sugar control enhancer (bitter melon extract) is first set, and the 13 kinds of germs are pretreated. This not only allows the raw materials to play a synergistic role and increase the stability of product quality, but also removes impurities by washing, drying and crushing the germs, controls the appropriate moisture content and fineness, and increases the release of nutrients. At the same time, the mixing links in the preparation process are controlled, such as mixing the raw materials in a specific order, controlling the mixer speed, mixing time and addition speed of the sugar control enhancer in each mixing stage, which can effectively improve the fusion between the raw materials, thereby improving the overall quality of the sugar-control compound instant cereal powder.

[0024] In addition, bitter melon saponins, polypeptide-P, alkaloids and flavonoids in the sugar control enhancer (bitter melon extract) will be combined with black rice powder, mulberry leaf powder, kudzu root powder, polygonatum powder and 13 kinds of germs for a second time; bitter melon saponins and 1-deoxynojirimycin in mulberry leaf powder undergo dehydration condensation to enhance the inhibition of α-glucosidase and strengthen the sugar control effect; polypeptide-P undergoes an esterification-like reaction with puerarin in kudzu root powder, optimizing insulin signal transduction and enhancing the cell's ability to absorb glucose; bitter melon saponins undergo an acetal reaction with polysaccharides in polygonatum powder to regulate the sugar metabolism process; flavonoids act synergistically with anthocyanins in black rice powder to resist oxidation and protect pancreatic cells; polypeptide-P reacts with proteins in 13 kinds of germs to regulate the activity of sugar metabolism enzymes.

[0025] By mixing a variety of raw materials and controlling the parameters of the preparation process, including the order of adding various raw materials and the mixing time, it is beneficial to fully exert the synergistic effect between the raw materials, increase the stability of product quality, and not only improve the integration between the raw materials, but also make the nutrients more evenly distributed, and improve the sugar control effect. In addition, the pretreatment of 13 kinds of germs removes impurities while increasing the release of nutrients. In addition, the secondary combination of bitter melon extract and other raw materials regulates sugar metabolism from multiple pathways, thereby improving the overall quality of the sugar-controlling compound instant grain powder.

[0026] By using bitter melon extract as a sugar control enhancer, the bitter melon saponins, polypeptide-P, alkaloids and flavonoids it contains are combined with other raw materials for a second time. Through the reaction with raw materials such as mulberry leaf powder and kudzu root powder, the sugar control effect is comprehensively enhanced from inhibiting α-glucosidase activity, optimizing insulin signal transduction, to regulating sugar metabolism and anti-oxidation. At the same time, it can also regulate the activity of sugar metabolism enzymes, providing people with blood sugar management with a convenient, efficient and nutritious instant food, which is conducive to maintaining stable blood sugar.

[0032] Test example The purpose of this experimental group is to explore the effects of different ingredient ratios on the instant cereal powder and to detect the sugar control effectiveness, nutritional balance and nutrient release rate of the instant cereal powder of the present invention.

[0033] Experimental objectives: Experimental groups A, B, and C respectively adopted the ingredient ratios of the prepared cereal powder provided in Examples 1-3; the control group A, B, C, and D were used as the control examples, wherein: Control group A Raw material dosage: The raw material dosage used in Example 1 is adopted, but without adding the sugar control synergist; Preparation method: The preparation steps of Example 1 are adopted, but the step of mixing the sugar control synergist is not included.

[0034] Control group B Ingredients: Black rice flour: 240g; Mulberry leaf powder: 90g; Kudzu root powder: 110g; Polygonatum root powder: 50g; 13 kinds of germ (each): 20g; Sugar control enhancer (bitter melon extract): 70g; Preparation method: adopt the preparation steps of Example 1.

[0035] Control group C Ingredients: Oat flour: 200g, buckwheat flour: 150g, pumpkin flour: 100g and konjac flour: 50g; Preparation method: Pour oat flour, buckwheat flour, pumpkin flour and konjac flour into a mixer in order, mix at a speed of 30r / min for 30min, and make traditional sugar-controlled compound instant cereal powder.

[0036] Control group D Raw material dosage: 300g ordinary rice flour, 200g corn flour and 150g oat flour; Preparation method: Pour rice flour, corn flour and oat flour directly into a mixer and mix them at a speed of 30r / min for 20min to make a composite instant grain powder.

[0037] Test method: The sugar control effectiveness, nutritional balance and nutrient release rate of the cereal powder prepared according to the present invention were tested respectively. The specific test methods are as follows: Effectiveness of sugar control: A certain number of hyperglycemic model animals (e.g., rats) were randomly divided into experimental groups A, B, and C and control groups A, B, C, and D, with equal numbers in each group. The animals were fasted for 12 hours before the experiment. During the experiment, each group was given an equal amount of the corresponding prepared cereal powder. Blood samples were collected regularly, and blood glucose levels were measured using a glucometer. The changes in blood glucose levels in the different groups of animals over the same time period were observed and compared to evaluate the effectiveness of the prepared cereal powder in controlling blood glucose.

[0038] Nutritional balance: Using professional nutrient testing equipment, such as mass spectrometers and amino acid analyzers, the macronutrients (protein, fat, carbohydrates), micronutrients (vitamins, minerals) and other bioactive ingredients (such as flavonoids, polysaccharides, etc.) in the prepared cereal powder of each experimental group and the control group were accurately measured. With reference to authoritative standards such as the Chinese Dietary Reference Intakes (DRIs), the reasonableness of the proportions of various nutrients in the cereal powder was evaluated and the degree of nutritional balance was determined.

[0039] Nutrient release rate: Using an in vitro simulated digestion model, the prepared cereal powders from each experimental and control groups were sequentially placed in digestive fluids simulating the mouth, stomach, and small intestine. They were stirred and digested at 37°C, following the time and conditions of normal human digestion. Samples were collected at specific time points during the oral digestion phase (simulating chewing for 5-10 minutes), gastric digestion phase (2-3 hours), and small intestinal digestion phase (3-4 hours). Appropriate assays, such as the biuret method for protein release and the iodine-starch colorimetric method for starch digestibility, were used to calculate the proportion of nutrients released from the cereal powder into the digestive fluids, yielding the nutrient release rate.

[0040] Specific detection indicators are shown in Table 2.

[0041] Table 2 Test indicators of each sample Sugar control effectiveness % (relative value of blood sugar change) Nutritional balance % (the degree to which the proportion of nutrients meets the standard) Nutrient release rate (at the end of the small intestine digestion phase) Experimental group A Blood sugar reduced by 35 90 80 Experimental group B Blood sugar reduced by 32 86 75 Experimental Group C Blood sugar reduced by 37 89 78 Control group A Blood sugar reduced by 20 74 62 Control group B Blood sugar reduced by 24 78 66 Control group C Blood sugar decreased by 27 81 70 Control group D Blood sugar reduced by 12 70 58 according to Figure 2-Figure 4 As shown in Table 2, the summary of the above comparative data is as follows: Effectiveness of sugar control: In terms of the effectiveness of blood sugar control, experimental groups A, B, and C showed better effects. The blood sugar level of experimental group A decreased by 35%, the blood sugar level of experimental group B decreased by 32%, and the blood sugar level of experimental group C decreased by 37%, which shows that the instant cereal powder prepared by the embodiment of the present invention can effectively reduce the blood sugar level of hyperglycemic model animals; in contrast, the blood sugar level of control group A only decreased by 20% because no blood sugar control enhancer was added, highlighting the key role of bitter melon extract in improving the blood sugar control effect; although the enhancer was added to the control group B, the blood sugar level decreased by 24% due to the change in the amount of raw materials, indicating that the proportion of raw materials has a greater impact on the blood sugar control effect; the control group C used a traditional formula, and the blood sugar level decreased by 27%, and the control group D used an ordinary cereal powder formula, and the blood sugar level decreased by only 12%, both of which were far lower than the experimental groups.

[0042] Nutritional balance: Regarding nutritional balance, the nutritional component ratio of test group A met the standard by 90%, test group B by 86%, and test group C by 89%, indicating that the present invention achieves a scientific combination of various nutrients by precisely setting the dosage of black rice flour, mulberry leaf powder, kudzu root powder, polygonatum powder, 13 kinds of germs and sugar control enhancers, so that the cereal flour achieves a high degree of balance in macronutrients, micronutrients and other bioactive ingredients; while the nutritional balance index of control groups AD is between 70% and 78%, which is lower than that of the test group, further verifying the efficacy of the formula of the present invention in nutritional balance.

[0043] Nutrient release rate: In terms of nutrient release rate, at the end of the small intestinal digestion stage, the release rates of test groups A, B, and C were 80%, 75%, and 78%, respectively. This shows that in the simulated human digestion process, the nutrients of the instant cereal powder of the present invention can be released from the cereal powder more efficiently, which is beneficial to the body's absorption; the nutrient release rate of the control groups AD was between 58% and 66%, which was significantly lower than that of the test group; this was due to the pretreatment of the 13 types of germs and the control of the mixing link in the preparation process, which improved the fusion between the raw materials and promoted the release of nutrients.

[0044] It can be seen that the present invention sets the amount of raw materials, pre-treats 13 kinds of germs, controls the preparation process parameters (such as mixing order, speed, time, etc.), selects bitter melon extract as a sugar control enhancer and utilizes its secondary binding properties with other raw materials. The prepared sugar-controlling compound instant cereal powder has obvious effects in terms of sugar control effectiveness, nutritional balance and nutrient release rate compared with the control example. It can provide a higher quality and more efficient instant food option for people who manage blood sugar, and can better meet their needs in sugar control and nutritional intake.
