Description

Technical Field

[0001] The invention belongs to the technical field of functional food processing, and particularly relates to a gluten-free, high-calcium, selenium-enriched Jerusalem artichoke nutritional powder and a preparation method thereof. Background Art

[0002] Traditional nutritional powders are mostly based on wheat flour, soy protein, and other ingredients, posing the risk of gluten residue. They also rely on chemical additives for fortification of trace elements like calcium and selenium, leading to low absorption and safety concerns. Existing gluten-free nutritional powders are mostly based on single ingredients like rice flour and quinoa flour, resulting in a single nutritional profile and insufficient levels of key nutrients like calcium and selenium. Some products are fortified with chemical calcium supplements (such as calcium carbonate) or inorganic selenium (such as sodium selenite), which have low bioavailability and potential side effects. There is a lack of nutritional powder formulas that center around selenium-rich Jerusalem artichoke and combine multiple medicinal and edible ingredients for synergistic benefits, making it difficult to simultaneously meet the multiple needs of being gluten-free, high in calcium, rich in selenium, and promoting intestinal health. Jerusalem artichoke, a natural, green, and pollution-free ingredient, is gaining attention for its rich functional ingredients and high nutritional value. The Jerusalem artichoke tuber, rich in trace elements, vitamins, and dietary fiber, is one of the vegetables with significant health benefits and an ideal ingredient for developing nutritional health foods. Selenium-rich Jerusalem artichokes can significantly increase their organic selenium content through bioaccumulation technology, making their selenium forms (such as selenomethionine) more easily absorbed and utilized by the human body. Furthermore, various medicinal and edible ingredients (such as Tremella fuciformis, shiitake mushrooms, and wolfberries) are rich in active polysaccharides, flavonoids, and trace elements, which synergize with Jerusalem artichokes to enhance their nutritional benefits. Summary of the Invention

[0003] The present invention aims to provide a gluten-free, high-calcium, selenium-rich Jerusalem artichoke nutritional powder, which uses selenium-rich Jerusalem artichoke as the core raw material and is compounded with a variety of medicinal and edible ingredients (including mushrooms, rhizomes, seeds, flowers, fruits and Chinese medicinal materials).

[0022] ④ Completely eliminate gluten-derived raw materials such as wheat, barley, and rye, and ensure gluten-free through formula design (test results comply with GB / T 23779-2009).

[0023] The specific preparation method is:

[0024] The present invention provides a gluten-free high-calcium selenium-rich Jerusalem artichoke nutritional powder and a preparation method thereof. The powder comprises, by mass, 20-30% of selenium-rich Jerusalem artichoke, 15-25% of selenium-rich mushrooms, 10-20% of rhizomes, 15-25% of seeds / beans, 5-10% of flowers, fruits / vegetables, 8-15% of Chinese medicinal materials, and 5-10% of other functional raw materials. The selenium-rich Jerusalem artichoke is a selenium-rich Jerusalem artichoke tuber during frost season. The selenium-rich mushrooms include selenium-rich black fungus, white fungus, shiitake mushroom, hericium erinaceus, king oyster mushroom, cordyceps flower, deer antler, etc. mushrooms; the root vegetables include yam, sweet potato, potato, and lotus root; the seeds / legumes include quinoa, corn, brown rice, sorghum rice, kidney-shaped black beans, chickpeas, lentils, red beans, and soybeans; the flowers and fruits / vegetables include day lily, carrots, purple cabbage, celery, and onions; the Chinese medicinal materials include mulberry leaves, wolfberries, ganoderma lucidum, American ginseng, Panax notoginseng, mulberries, sea buckthorn, and cranberries; the other functional ingredients include seaweed, black sesame, flax seeds, green tea, ginger, cinnamon, onions, hawthorn, and acerola cherry.

[0025] The selenium-rich Jerusalem artichoke in the present invention is the selenium-rich Jerusalem artichoke tuber during frost. The present invention does not limit the specific source of the selenium-rich Jerusalem artichoke added to the Jerusalem artichoke nutritional powder. The addition amount of selenium-rich Jerusalem artichoke in the present invention is 20-30%, preferably 25-28%, and more preferably 25%. The present invention grinds the selenium-rich Jerusalem artichoke into a slurry, and then pre-freezes it, controlling the pre-freezing temperature to -17°C so that the Jerusalem artichoke is fully frozen at this temperature to form a stable ice crystal structure; then sublimation drying is performed, controlling the drying temperature to -50°C, so that the ice crystals in the Jerusalem artichoke are directly sublimated into water vapor to remove most of the moisture; then analytical drying is performed, controlling the drying temperature to -50°C, removing residual bound water and adsorbed water, and ensuring that the dryness of the Jerusalem artichoke meets the preservation requirements; the dried Jerusalem artichoke is crushed and passed through a 200-300 mesh sieve. The invention performs pre-freezing, sublimation drying and analytical drying treatments on the selenium-rich Jerusalem artichoke slurry, thereby retaining the high nutritional components of the Jerusalem artichoke tubers during frost, such as active substances such as inulin, to the greatest extent, improving the taste and stability of the Jerusalem artichoke nutritional powder, and providing a good basis for subsequent compounding with other raw materials.

[0026] The selenium-rich mushrooms in the present invention include selenium-rich wood ear, white fungus, shiitake mushroom, hericium erinaceus, king oyster mushroom, cordyceps flower, and velvet antler mushroom. The mushrooms added in the present invention may be any one species or a mixture of any two or more. The present invention does not limit the specific source of the mushrooms added to the Jerusalem artichoke nutritional powder. The amount of mushrooms added in the present invention is 15-25%, preferably 16-20%, and more preferably 17%. The present invention pre-treats the mushrooms by placing the washed mushrooms on a steaming plate, adding water to a steamer and bringing to a slight boil. The plate is then placed on the steamer and steamed (100°C for 30 minutes). The mushrooms are then removed, crushed to form a slurry, spray-dried (inlet air temperature 180°C, flow rate 15 mL / min), and finally passed through a 100-mesh sieve (sieve aperture diameter approximately 150 microns) to obtain a dry powder with a particle size of less than 150 microns. The present invention allows the mushrooms to be mixed and steamed, or each mushroom species can be steamed separately. The present invention does not limit the specific crushing and spray drying methods for the mushrooms. The present invention has the following significant advantages: spray drying after slurrying can maximize the retention of nutrients and active substances in the mushrooms, such as polysaccharides, which help improve human immunity, and avoids the impact of multiple operations in traditional methods on product quality, rough taste, and poor stability; the steaming process can better retain the flavor of the raw materials, giving the product a rich mushroom fragrance; the particle size distribution is uniform, with an angle of repose between 30° and 35°, good fluidity, and good solubility.

[0027] The root vegetables described in the present invention include yam, sweet potato, potato, and lotus root. The root vegetables added in the present invention can be any one or a mixture of any two or more. The present invention does not limit the specific source of the root vegetables added to the Jerusalem artichoke nutritional powder. The amount of root vegetables added in the present invention is 10-20%, preferably 12-18%, and more preferably 16%. The present invention pre-treats the root vegetables by: placing washed root vegetable slices on a steaming plate, adding water to a steamer and boiling until slightly boiling, then placing the plate on the steamer, steaming (100°C, 30 minutes), removing the slices, crushing them into a slurry, spray drying (inlet air temperature 180°C, flow rate 15 mL / min), and finally passing through a 100-mesh sieve (sieve aperture diameter approximately 150 microns) to obtain a dry powder with a particle size of less than 150 microns. The present invention allows the root vegetables to be mixed and then steamed, or each type can be steamed separately. The present invention does not limit the specific crushing and spray drying methods of the rhizomes. The present invention has the following significant advantages: steaming retains the carotenoids and high mucin content therein, which are conducive to digestion and absorption, and the taste is also better.

[0028] The seeds / beans described in the present invention include quinoa, corn, brown rice, sorghum rice, kidney-shaped black beans, chickpeas, lentils, adzuki beans, soybeans, and peas; the beans added in the present invention can be any one or a mixture of any several. The present invention does not limit the specific source of seeds / beans added to Jerusalem artichoke nutritional powder. The amount of seeds / beans added in the present invention is 15-25%, preferably 18-22%, and more preferably 20%. The present invention pre-treats the beans, and the pre-treatment method is classified according to the nutrient content of the beans: high-protein beans (such as kidney-shaped black beans and soybeans) are first soaked, then ground into a slurry, cooked, cooled, and then added with natto powder to make natto; high-starch beans (such as chickpeas, lentils, adzuki beans, peas, etc.) are first soaked and germinated, then ground into a slurry, then enzymatically hydrolyzed into peptides and spray-dried, and finally sieved to the required fineness (such as 200-300 mesh). The enzymatic hydrolysis process is carried out at a pH of 6.5-7.5 and a temperature of 45-55°C. Other seeds (quinoa, corn, brown rice, etc.) are then germinated and ground into a slurry together with sorghum rice and spray-dried. The inlet air temperature for the spray drying process is 180-200°C and the feed rate is 15-25 mL / min. Compared with previous methods, the present invention has the following significant advantages: 1. Nutritionally rich: The germination and enzymatic hydrolysis process increases the content of vitamins (such as B vitamins, vitamin C, vitamin E, etc.) and minerals (such as calcium, iron, magnesium, zinc, etc.), making them more easily absorbed by the human body. At the same time, new nutrients are produced. For example, the content of gamma-aminobutyric acid in germinated brown rice is significantly increased, which has sedative, blood pressure-lowering, and sleep-improving effects; active substances such as polyphenols and flavonoids are increased in germinated quinoa. 2. Good digestion and absorption: The enzymes in the seeds are activated, breaking down macromolecules such as starch, protein, and fat, converting them into small molecules such as reducing sugars, amino acids, and fatty acids, making them easier to digest and absorb. For example, after quinoa germinates, the starch content decreases and the reducing sugar content increases; after corn germinates, the activity of enzymes such as amylase and protease increases, and insoluble macromolecules are decomposed into soluble components; 3. Anti-nutritional factors are reduced: anti-nutritional factors such as phytic acid and saponins are decomposed during the germination and enzymatic hydrolysis process, reducing their interference with mineral absorption and enabling the human body to absorb nutrients more fully; 4. Antioxidant enhancement: The content of antioxidants such as polyphenols and flavonoids increases, which helps to eliminate free radicals in the body, reduce oxidative damage, and prevent chronic diseases; 5. Promote intestinal health: The increase in dietary fiber content can increase the volume of intestinal contents, stimulate intestinal peristalsis, promote the growth of beneficial intestinal bacteria, maintain the normal function of the digestive system, and prevent intestinal diseases such as constipation.In addition, after natto is made, the natto bacteria germinate and proliferate in the intestines, playing an important regulatory role in the microecological balance of intestinal flora and ensuring the normal functioning of intestinal function; 6. Cardiovascular health maintenance: Nattokinase in natto has the property of dissolving fibrin, which can help reduce blood viscosity and inhibit abnormal platelet aggregation, thereby reducing the risk of thrombosis; soy isoflavones, anthocyanins and other ingredients in black bean natto are also helpful for cardiovascular health; 7. Control blood sugar: Germination can reduce the glycemic index of food, and the dietary fiber and polysaccharides therein can promote the secretion and absorption of insulin, which helps lower blood sugar and prevent diabetes; 8. Enhance immunity: Rich nutrients and bioactive substances help enhance the body's immunity and improve resistance.

[0029] The fruits / vegetables described in the present invention include day lilies, carrots, red cabbage, celery, and onions. The fruits / vegetables added in the present invention can be any one or a mixture of any two or more. The present invention does not limit the specific source of the fruits / vegetables added to the Jerusalem artichoke nutritional powder. The amount of fruits / vegetables added is 5-10%, preferably 6-8%, and more preferably 6%. The present invention pre-treats the fruits / vegetables by grinding them into a slurry and then freeze-drying them, preserving their active ingredients.

[0030] The Chinese medicinal materials described in the present invention include mulberry leaves, wolfberries, ganoderma lucidum, American ginseng, Panax notoginseng, mulberries, sea buckthorn, and cranberries. The Chinese medicinal materials added in the present invention can be any one kind or a mixture of any several kinds. The present invention does not limit the source of the Chinese medicinal materials specifically added to the Jerusalem artichoke nutritional powder. The amount of Chinese medicinal materials added in the present invention is 8-15%, preferably 8-12%, and more preferably 10%. The present invention pretreats the Chinese medicinal materials, and the pretreatment method is: low-temperature extraction of wolfberries, ganoderma lucidum, American ginseng, Panax notoginseng, mulberries, sea buckthorn, and cranberries, and then freeze-drying. The mulberry leaves specifically added to the Jerusalem artichoke nutritional powder of the present invention are protein mulberries after mulberries are harvested. The present invention pretreats the mulberry leaves, and the pretreatment method is: wash the surface impurities with clean water, grind into slurry, and then use specific enzymes (such as protease, cellulase, etc.) under suitable conditions (such as pH 6.8 ～ 7.2, Temperature 45 ～50 ℃) for enzymatic hydrolysis to obtain mulberry leaf peptide, which is freeze-dried and passed through an 80-mesh sieve (particle size less than 0.18 mm) to obtain mulberry leaf peptide powder. The present invention does not limit the specific crushing, enzymatic hydrolysis, drying and sieving methods of mulberry leaves. The present invention retains the nutritional components and active substances of mulberry leaves, such as mulberry leaf peptides, flavonoids, etc., to the greatest extent by crushing, enzymatic hydrolysis, drying and sieving mulberry leaves. These components act synergistically with mulberry leaf peptides to enhance the functional activity of mulberry leaf peptides, while solving the problem that mulberry leaves with high fiber content are difficult to crush directly, improving the taste and stability of mulberry leaf powder, and providing a good foundation for subsequent compounding with other raw materials.

[0031] The other functional ingredients described in the present invention include laver, black sesame, flaxseed, green tea, ginger, cinnamon, onion, hawthorn, and acerola cherry; these other functional ingredients may be any one or a mixture of any two or more. The present invention does not limit the specific sources of the other functional ingredients added to the Jerusalem artichoke nutritional powder. The functional ingredients are added in an amount of 5-10%, preferably 6-8%, and more preferably 6%. The functional ingredients are pretreated by low-temperature drying and low-temperature airflow milling, with the onion, hawthorn, and acerola cherry being low-temperature ground and then freeze-dried.

[0032] The present invention mixes the selenium-rich Jerusalem artichokes, selenium-rich mushrooms, rhizomes, seeds / beans, flowers, fruits / vegetables, Chinese medicinal materials, and other functional raw materials obtained by the above pretreatment in a high-energy mixer and sterilizes them. The present invention does not limit the specific mixing method and sterilization method.
