Problems solved by technology

[0005] The whole-structured leaf active peptide nutrition prepared with the leaves as the main raw material needs to solve the following scientific and technological problems: one is to solve the protein, especially the one-time degradation of the leaf protein, which is easy to form a large amount of amino acids and produce a very small amount of active peptides, that is, converted into active peptides. The worldwide problem of low peptide conversion rate has broken through the international standard of ≤38%, and achieved a one-time condensation conversion rate of ≥90%; the second is to solve the conversion of structural leaf fat into various low-level fatty acids; the third is to maximize the retention of structural The unique health nutrients in the leaves, such as flavonoids, V B , V E , V C Vitamins and trace elements; the fourth is to solve the technical problem that the biochemically produced active peptides are not easy to separate from the high gelatinous solution caused by high starch and high fiber

Embodiment 1

[0023] 1) Select 70kg of dry, mildew-free and impurity-free leaves and add 30kg of plant protein isolate powder (it can be peanut, soybean, pea, broad bean, walnut and other protein powders). Clean and mix the leaves and put them in 26 Soak in pure water at ℃ for 6 hours;

[0024] 2) Drain the soaked leaves and mix them with vegetable protein powder as an auxiliary material, add 700kg of pure water and pass through a refiner to pulp;

[0025] 3) subdividing the above-mentioned slurry through a colloid mill for 4 times, and then passing through a 100Mpa ultra-high pressure homogenization for 2 times, further subdividing the treatment, so that the slurry reaches 550 mesh;

[0026] 4) The treated slurry in step 3) is subjected to a high temperature treatment of 7 atmospheric pressure and 142° C. for 5 minutes, and the starch in the leaves of the leaves is alpha-treated, and the protein of the leaves of the leaves is further denatured;

[0027] 5) Cool the further denatured and α...

Embodiment 2

[0036] 1) Select 100kg of dry leaves without mildew and impurities, wash them with pure water, and soak them in pure water at 24°C for 4 hours;

[0037] 2) Drain the soaked mulberry leaves and add 600kg of pure water to pulp through a refiner.

[0038] 3) Subdivide the above-mentioned slurry 4 times through a colloid mill, then homogenize 2 times through a 100Mpa ultra-high pressure, and further subdivide the slurry to make the slurry reach 510 mesh;

[0039] 4) The treated slurry in step 3) is subjected to a high temperature treatment of 6 atmospheric pressure and 139° C. for 3 minutes, and the starch in the leaves of the leaves is alpha-treated, and at the same time, the leaves of the leaves are further denatured;

[0040] 5) Cool the further denatured and α-treated materials to 55°C through a tubular heat exchanger, adjust the pH value of the slurry to 7, and then add 0.5% neutral protease, 0.08% lipase and 0.6% starch Enzyme, then carry out the pulse type dynamic impact s...

Abstract

The invention discloses whole paper mulberry leaf bioactive peptide nutriment. The whole paper mulberry leaf bioactive peptide nutriment contains 2-90% of bioactive peptides, linoleic acid, oleic acid, flavones, potassium, calcium, iron, zinc, selenium, VB, VC, VE and sugar. The whole paper mulberry leaf bioactive peptide nutriment is prepared by the following method: putting soaked paper mulberryleaves in purified water, performing pulping, performing comminuting treatment in a colloidal mill, and performing homogenization at least twice using ultra-high pressure of 100Mpa or higher until the fineness of pulp reaches 510-550 meshes and the pulp is sufficiently denaturalized; performing gelatinization at atmospheric pressure of 6-7 and high temperature of 139-142 DEG C; cooling the material subjected to the gelatinization treatment to 55-65 DEG C, adjusting the pH value of the pulp to 7-8, adding neutral proteinase, lipase and amylase, performing impulse type impact stirring at 2800-3000rpm, and performing enzyme deactivation and sterilization after standing and biochemical treatment; performing precipitating using a precipitating system to obtain a whole paper mulberry leaf bioactive peptide stock solution, performing concentrating and filtering and preparing the whole paper mulberry leaf bioactive peptide nutriment.

Description

technical field [0001] The invention belongs to the field of bioengineering, and relates to a whole-structure leaf active peptide nutrient and a preparation method thereof. The active peptide is a mixture of compounds such as oligopeptides, short peptides and polypeptides. Background technique [0002] The mulberry tree, also known as the mulberry tree and the valley tree, belongs to the deciduous tree of the Moraceae plant, and has abundant resources in my country. Structural leaves (dry) protein up to 20-26%, crude fiber 9.69-15.6%, crude fat 5.31-11.94%, calcium 3.15%, phosphorus 0.5%, iron 0.08%, V B , V E , V C Nutrients such as vitamins, trace elements and flavonoids are also very rich. Because it has all kinds of amino acids, especially an amino acid that is necessary for the human body and cannot be synthesized by itself, it not only belongs to high-quality protein, but also has high dietary and medicinal value. , improving eyesight, clearing away heat, cooling ...
