Description

Technical Field

[0001] This invention relates to the field of food technology, specifically to a protein powder that promotes bowel movements. Background Technology

[0002] Protein powder is a powdered dietary supplement purified and processed from high-quality raw materials such as soybeans and whey. Its core function is to efficiently supplement the body with protein that is difficult to obtain in sufficient quantities from daily diet. Protein powder can not only serve as a basic raw material for muscle growth and repair, helping athletes improve muscle quality, but also accelerate tissue repair for postoperative patients and the elderly. At the same time, it participates in the synthesis of immunoglobulins to enhance the body's resistance. It can also assist in weight management by increasing satiety. It is a convenient nutritional supplement choice for improving protein deficiency and maintaining normal metabolism.

[0003] Chinese Patent CN101461539B discloses a method for preparing protein powder. The method involves adding probiotics to the edible protein powder and then anaerobically culturing it in an aqueous medium to hydrolyze the protein. This invention, by adding probiotics capable of producing proteases to the edible protein powder, replaces or enhances the role of proteases in food additives, significantly increasing the hydrolysis rate of the protein powder within a certain time. The method described in this invention is more convenient and economical than simply adding proteases; the resulting protein powder is richer in nutrients and more easily absorbed by the human body.

[0004] In existing technologies, most protein powders only focus on protein supplementation and lack the function of assisting in improving bowel movements. They cannot simultaneously meet the body's dual needs for protein supplementation and intestinal health. Some protein powders with added dietary fiber have problems such as poor integration of dietary fiber and protein, poor solubility, rough taste, and insignificant bowel movement improvement, ultimately leading to difficulty in defecation.

[0005] Therefore, we proposed a protein powder that promotes bowel movements in order to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a protein powder that promotes bowel movements, in order to solve the problems mentioned in the background art, such as poor integration of dietary fiber with protein, poor solubility, rough taste, and insignificant bowel movement improvement, which ultimately leads to difficulty in defecation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a protein powder that promotes bowel movements, composed of whey protein powder, casein powder, inulin, fructooligosaccharides, psyllium husk powder, soybean lecithin, and β-mannanase. The raw materials are composed of the following total weight parts: 30-50 parts whey protein powder, 15-25 parts casein powder, 8-15 parts inulin, 5-10 parts fructooligosaccharides, 3-8 parts psyllium husk powder, 2-6 parts soybean lecithin, and 0.1-0.5 parts β-mannanase.

[0008] Preferably, the whey protein powder is whey protein isolate with a protein content ≥90% and is lactose-free, and the casein powder is sodium caseinate with a protein content ≥85%.

[0009] Preferably, the degree of polymerization of inulin is 2-60, the degree of polymerization of fructooligosaccharides is 2-4, and the weight ratio of the two is 1.2-2.5:1.

[0010] Preferably, the psyllium husk powder has a particle size of 100-200 mesh, a dietary fiber content of ≥80%, and is subjected to low-temperature drying treatment at a temperature not exceeding 60℃.

[0011] Preferably, the β-mannanase has an enzyme activity of 1000 U / g-5000 U / g, and retains more than 80% of its maximum enzyme activity when incubated at 30℃-70℃ and pH 3.0-11.0 for 60 min. The soybean lecithin is food grade and has a phospholipid content ≥95%.

[0012] This invention also provides a method for preparing a laxative protein powder, characterized by comprising the following steps: S1. Raw materials and processing: Whey protein powder and casein powder are separately ground into pulverizers to 80-100 mesh, and impurities are removed by sieving through a sieve before use. Psyllium husk powder is ground to a small particle size and then dried at a temperature not exceeding 60℃ to remove moisture before use, ensuring the purity of the raw materials and the stability of subsequent processing. S2. Raw material mixing: According to the weight ratio described in claim 1, the pretreated whey protein powder, casein powder, psyllium husk powder, inulin, fructooligosaccharide, soybean lecithin, and β-mannanase are added to a mixer and stirred for 15-30 minutes to ensure that all raw materials are fully integrated and evenly distributed to obtain a mixture with a consistent texture. S3. Homogenization of the mixture: Add the well-mixed mixture to deionized water, adjust the solid-liquid ratio to 1:3-5, and after the material is initially dissolved by stirring, put it into a homogenizer and homogenize it for 60s-180s at a speed of 20000r / min-35000r / min to break up the agglomerated particles and obtain a uniform, stable, and lumpy homogenized liquid. S4. Drying: The prepared homogenized liquid is sent into a spray drying equipment. The inlet air temperature is set to 160℃-180℃ and the outlet air temperature is set to 70℃-85℃. The water in the homogenized liquid is evaporated by hot air, so that the material is dried and shaped instantly. After drying, a semi-finished product of defecation-promoting protein powder with fine texture and good fluidity is obtained, ensuring that the moisture content of the finished product meets the standard. S5. Screening and Packaging: The dried protein powder semi-finished product is screened through a 100-mesh standard sieve to remove impurities and coarse particles, ensuring that the finished product has a uniform particle size. After passing the screening, it is individually sealed with food-grade sealing packaging materials to prevent moisture absorption and deterioration, and finally obtains qualified protein powder finished product that promotes bowel movement.

[0013] Preferably, in S1, the pulverizing equipment is a food-grade pulverizing equipment, the pulverizing speed is controlled at 2000-3000 r / min, and the pulverized material is sieved using an 80-100 mesh standard sieve. After sieving, the purity of whey protein powder and casein powder needs to be tested to ensure that there are no impurities remaining and that the particle size meets the requirements of 80-100 mesh, thus laying the foundation for subsequent raw material mixing.

[0014] Preferably, in S2, the mixer is a food-grade mixing device, the stirring speed is controlled at 300r / min-500r / min, and an intermittent stirring mode is adopted during the stirring process. After stirring continuously for 5 minutes, the stirring is stopped for 1 minute, and the cycle is repeated until the stirring is finished.

[0015] Preferably, in step S3, the mixture is first mixed with deionized water in a certain proportion and preheated in a constant temperature water bath at 50℃-60℃ for 10-15 minutes. During the preheating process, the mixture is continuously stirred to allow the material to initially dissolve and maintain a stable temperature. After preheating, the mixture is then homogenized.

[0016] Preferably, in S4, the spray drying adopts a centrifugal spray dryer, the atomization pressure of the equipment is adjusted to 0.2MPa-0.4MPa, the feeding speed is controlled at 20mL / min-30mL / min, and the inlet and outlet air temperatures are kept stable. Through centrifugal atomization, the homogenized liquid is formed into droplets, which are fully in contact with the hot air and quickly dried to obtain a protein powder semi-finished product with uniform particle size and fine texture.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention combines protein supplementation with gut health conditioning. Whey protein powder and sodium caseinate complement each other to ensure efficient protein absorption. Inulin, fructooligosaccharides, and psyllium husk powder work synergistically to gently promote intestinal peristalsis and regulate gut microbiota. β-mannanase reduces the digestive burden on the intestines, and soybean lecithin improves taste and solubility, achieving dual health benefits.

[0018] This invention preserves the nutritional activity of raw materials through raw material selection and pretreatment processes. Homogenization, spray drying, and other steps ensure that the finished protein powder has uniform particle size, good solubility, delicate taste, no clumping, and no harmful impurities, making it suitable for consumption by various groups of people.
