[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0021] Example 1, a hemp peptide nutritional fat-reducing meal replacement, includes the following raw materials in a weight ratio: 10 parts of the hemp peptide powder, 5 parts of compound dietary fiber, 22 parts of plant protein complex, 1.5 parts of hemp seed oil microcapsule powder, 1.5 parts of vitamin and mineral premix, and 5 parts of natural fruit powder flavor regulator.

[0024] The natural fruit powder flavor regulator includes 2 parts of stevioside, 5 parts of freeze-dried strawberry powder, and 1 part of vanilla essence.

[0025] A method for preparing a hemp peptide nutritional fat-reducing meal replacement, comprising the following steps:

[0026] Step 1: Mix defatted hemp seed meal with water at a material-liquid ratio of 1:8, adjust the pH to 9.0, perform alkaline extraction at 50°C for 2 hours, centrifuge and collect the supernatant, add alkaline protease and papain for enzymatic hydrolysis, adsorb the enzymatic solution on activated carbon, separate it through a 3kDa ultrafiltration membrane, and freeze-dry it in a vacuum to obtain hemp peptide powder;

[0028] Step 3: add functional factors and natural fruit powder flavor regulator, mix for 15 minutes, and then package to obtain meal replacement powder.

[0029] The subpackaging step in step 3 adopts nitrogen-filled packaging, and the oxygen content in the packaging bag is ≤0.5% to extend the shelf life of the product and maintain the stability of the active ingredients. In step 2, the mixing speed of the three-dimensional mixer is 20 rpm and the mixing time is 30 minutes to ensure that the components are evenly dispersed.

[0030] Example 2, a hemp peptide nutritional fat-reducing meal replacement, comprising the following ingredients by weight:

[0031] 25 parts of hemp peptide powder, 30 parts of complex dietary fiber, 20 parts of plant protein complex, 2 parts of hemp seed oil microcapsule powder, 1 part of vitamin and mineral premix, and 3 parts of natural fruit powder flavor regulator.

[0032] The composite dietary fiber comprises 10 parts of starch, 8 parts of inulin, and 3 parts of psyllium husk powder; the plant protein complex comprises 8 parts of soy protein isolate, 5 parts of pea protein, and 1 part of chia seed powder; and the functional factors comprise hemp seed oil microcapsule powder and vitamin and mineral premix in a weight ratio of 2:1.

[0033] The natural fruit powder flavor regulator includes 2 parts of steviol glycosides, 5 parts of freeze-dried strawberry powder, and 1 part of vanilla essence.

[0034] A method for preparing a hemp peptide nutritional fat-reducing meal replacement, comprising the following steps:

[0035] Step 1: Mix defatted hemp seed meal with water at a material-liquid ratio of 1:8, adjust the pH to 9.0, perform alkaline extraction at 50°C for 2 hours, centrifuge and collect the supernatant, add alkaline protease and papain for enzymatic hydrolysis, adsorb the enzymatic solution on activated carbon, separate it through a 3kDa ultrafiltration membrane, and freeze-dry it in a vacuum to obtain hemp peptide powder;

[0036] Step 2: Put the hemp peptide powder, compound dietary fiber and plant protein complex into a three-dimensional mixer and mix them before granulating;

[0037] Step 3: add functional factors and natural fruit powder flavor regulator, mix for 15 minutes, and then package to obtain meal replacement powder.

[0038] The subpackaging step in step 3 adopts nitrogen-filled packaging, and the oxygen content in the packaging bag is ≤0.5% to extend the shelf life of the product and maintain the stability of the active ingredients. In step 2, the mixing speed of the three-dimensional mixer is 20 rpm and the mixing time is 30 minutes to ensure that the components are evenly dispersed.

[0039] Example 3, a hemp peptide nutritional fat-reducing meal replacement, comprising the following ingredients by weight:

[0040] 1 part of hemp peptide powder, 30 parts of complex dietary fiber, 20 parts of plant protein complex, 2 parts of hemp seed oil microcapsule powder, 1 part of vitamin and mineral premix, 3 parts of natural fruit powder flavor regulator.

[0041] The composite dietary fiber comprises 10 parts of starch, 8 parts of inulin, and 3 parts of psyllium husk powder; the plant protein complex comprises 8 parts of soy protein isolate, 5 parts of pea protein, and 1 part of chia seed powder; and the functional factors comprise hemp seed oil microcapsule powder and vitamin and mineral premix in a weight ratio of 2:1.

[0042] The natural fruit powder flavor regulator includes 2 parts of steviol glycosides, 5 parts of freeze-dried strawberry powder, and 1 part of vanilla essence.

[0043] A method for preparing a hemp peptide nutritional fat-reducing meal replacement, comprising the following steps:

[0044] Step 1: Mix defatted hemp seed meal with water at a material-liquid ratio of 1:8, adjust the pH to 9.0, perform alkaline extraction at 50°C for 2 hours, centrifuge and collect the supernatant, add alkaline protease and papain for enzymatic hydrolysis, adsorb the enzymatic solution on activated carbon, separate it through a 3kDa ultrafiltration membrane, and freeze-dry it in a vacuum to obtain hemp peptide powder;

[0045] Step 2: Put the hemp peptide powder, compound dietary fiber and plant protein complex into a three-dimensional mixer and mix them before granulating;

[0046] Step 3: add functional factors and natural fruit powder flavor regulator, mix for 15 minutes, and then package to obtain meal replacement powder.

[0047] The subpackaging step in step 3 adopts nitrogen-filled packaging, and the oxygen content in the packaging bag is ≤0.5% to extend the shelf life of the product and maintain the stability of the active ingredients. In step 2, the mixing speed of the three-dimensional mixer is 20 rpm and the mixing time is 30 minutes to ensure that the components are evenly dispersed.

[0048] Example 1 uses 10 parts of hemp peptide powder, which is a medium addition level, aiming to balance the efficacy of the active ingredients and cost; Example 2 increases the amount of hemp peptide powder to 25 parts to form a high-activity peptide formula, which is suitable for groups with higher demands for biological activity (such as patients with metabolic syndrome); Example 3 only uses 1 part of hemp peptide powder. Although it can provide basic antioxidant support, the concentration of active peptides is significantly reduced, which may affect the efficiency of fat loss. This formula focuses more on cost control or as a basic nutritional supplement.

[0049] In Example 1, the proportion of compound dietary fiber is 5 parts and the proportion of plant protein complex is 22 parts, forming a high-protein, high-fiber formula suitable for consumers who need to quickly feel full; Example 2 increases the compound dietary fiber to 30 parts and reduces the plant protein complex to 20 parts, which enhances the sugar control effect, but the protein density decreases, which may affect muscle maintenance ability; Example 3 has the same ratio of dietary fiber to plant protein as Example 2, but the amount of hemp peptide powder is sharply reduced, resulting in a decrease in the overall nutritional density, and it needs to be used in combination with other dietary supplements.

[0050] In Example 1, the ratio of hemp seed oil microcapsule powder to vitamin and mineral premix is ​​1:1, forming a balanced fat metabolism and nutritional supplement combination; Example 2 increases the amount of CLA to 2 parts, forming a 2:1 ratio with the vitamin and mineral premix, enhancing fat oxidation efficiency, but may increase the consumption of antioxidants such as vitamin E, and attention should be paid to nutritional balance; Although Example 3 maintains a 2:1 ratio of CLA to premix, due to the extremely low amount of hemp peptide powder, the antioxidant and immune enhancement functions are weakened, and the fat-reducing effect of CLA may be limited due to the lack of synergistic ingredients.

[0051] Example 1 achieves a rich fruity aroma and moderate sweetness by compounding a high proportion of freeze-dried strawberry powder and vanilla essence, which is suitable for the mass market; although Example 2 and Example 3 have the same ratio of natural fruit powder flavor regulator, the taste is different due to the difference in basic formula: Example 2 may produce a stronger sense of fullness due to the high fiber content (10 parts of starch + 8 parts of inulin + 3 parts of psyllium husk powder), but may affect the smoothness after brewing; Example 3 may weaken the product's carrying capacity for taste and flavor due to the low content of hemp peptide powder.

[0052] In summary, Example 1 strikes a balance between nutritional balance, metabolic regulation, and cost control, making it suitable for the mass market. While Example 2 demonstrates significant efficacy, it is relatively expensive and requires professional guidance. While Example 3 offers low cost, its efficacy is limited, and consumers must be clearly informed that it is positioned as a nutritional supplement, not a specialized fat-reducing product. All examples require nitrogen-filled packaging (oxygen content ≤ 0.5%) to ensure the stability of the active ingredient. However, Example 3, due to its low active ingredient content, requires a more rigorous packaging seal, necessitating an additional airtightness test.

[0053] The present invention adopts compound dietary fiber and plant protein complex to add vitamin and mineral premix to ensure that daily nutrient intake meets the standard and avoid the malnutrition problem easily caused by traditional meal replacement. Hemp peptide has high biological activity and assists fat reduction through antioxidant, lipid-lowering and immunity-enhancing mechanisms. Hemp seed oil microcapsule powder and hemp peptide work synergistically to improve fat oxidation efficiency and thus achieve fat reduction effect. The resistant starch and inulin in the compound dietary fiber form a double sugar control, prolonging gastric emptying time to 4-6 hours, reducing the post-meal blood sugar fluctuation by 40%, and avoiding the problem of insulin surge caused by traditional meal replacement. The combination of freeze-dried strawberry powder and vanilla essence gives the product a natural fruity aroma, a delicate taste and no graininess.
