Description

For producing polypeptide vegetables tailored version plant nutrient agent and preparation method thereof
Technical field
The present invention relates to plant nutrient agent, be particularly used for produce polypeptide vegetables tailored version plant nutrient agent and Its preparation method, belongs to agriculture field.
Background technology
Society, the nutrition and health care consciousness of people is increasingly stronger, and vegetables are the necessitys of our daily life, Enough vegetables intakes are to maintain healthy basic.Polypeptide has effect of health care, can control growth, Growth, immunological regulation and metabolism, mend peptide and mend activity exactly, mends peptide and mends vigor exactly, mends peptide and mends exactly Life.In common vegetable, content of peptides is the lowest, in order to allow the nutritional labeling of vegetables is more complete, quality is higher, More healthy, produce a kind of polypeptide vegetables tailored version nutritional agents that can increase vegetables content of peptides and just seem the heaviest Want.
Summary of the invention
Aim to provide a kind of polypeptide vegetables tailored version plant battalion that can increase vegetables content of peptides the mesh of the present invention Support agent.
It is to provide the preparation method for producing polypeptide vegetables tailored version plant nutrient agent another mesh of the present invention.
Technical scheme is as follows:
For producing polypeptide vegetables tailored version plant nutrient agent, raw material and mass fraction thereof be: dregs of beans: 15～ 20 parts, cotton dregs: 25～30 parts, brewex's grains: 15～30 parts, molasses: 2～5 parts, urea: 2～3 parts, Inorganic salts: 6～10 parts, sodium selenite: 0.003～0.005 part；Bacillus subtilis YS-45 kind daughter bacteria The volume accounting of suspension is 4%～8%, and wherein, inorganic salts are KH by mass ratio2PO4:MnSO4:ZnSO4: boron The mixture composition of sand=1～3:0.5～1.5:4～8:2～4, it is preferred that each composition quality of described inorganic salts Ratio is KH2PO4:MnSO4:ZnSO4: borax=2:1:6:3.
For producing the preparation method of polypeptide vegetables tailored version plant nutrient agent, comprise the following steps:
A, the preparation of bacillus subtilis YS-45 seed bacteria suspension:
A-1, the preparation of murphy juice: in mass ratio for potato: the ratio of water=1:4～6 prepares murphy juice, After potato is added water, boil 25～35 minutes, after filter and remove residue, obtain murphy juice；
A-2, the preparation of seed culture medium: according to for producing polypeptide vegetables tailored version plant nutrient agent The mass fraction of each raw material weighs other raw materials in addition to bacillus subtilis YS-45 seed bacteria suspension, The dregs of beans weighed, cotton dregs, brewex's grains, molasses, urea, inorganic salts, sodium selenite are added seed In culture vessel, add murphy juice to seed culture vessel volume 25～35%, 110～130 DEG C, Seed culture medium is obtained after sterilizing in 25～35 minutes；
A-3, actication of culture and cultivation: an activated spawn adds 9～11ml sterilized waters and makes bacteria suspension, Again bacteria suspension is inoculated in seed culture medium by the volume ratio of 4%～8%, then at 250r/min, Bacillus subtilis YS-45 seed bacteria suspension is i.e. obtained after cultivating 23～25 hours under the conditions of 35～39 DEG C；
B, weigh except withered grass according to the mass fraction for the raw material that produces polypeptide vegetables tailored version plant nutrient agent Other raw materials beyond bacillus YS-45 seed bacteria suspension, by the dregs of beans weighed, cotton dregs, brewex's grains, Molasses, urea, inorganic salts, sodium selenite add in fermentation tank, then add water to fermenter volume 65～ 75%, stirring mixing, sterilizing 25～35 minutes at 110～130 DEG C, add by the volume ratio of 4%～8% after cooling Enter the bacillus subtilis YS-45 seed bacteria suspension prepared, 250r/min, 35～39 DEG C, PH from Semi-finished product I are obtained after fermenting 46～50 hours under conditions of Ran；
C, above-mentioned semi-finished product I are filtered, add palm to the ratio that filtrate by volume percentage is 1%～2% Oil, obtains for producing polypeptide vegetables tailored version plant nutrient agent.
Wherein, when preparing bacillus subtilis YS-45 seed bacteria suspension, before prepared by seed culture medium Within one day, carry out bacillus subtilis YS-45 actication of culture.
Preferably, in mass ratio for potato time prepared by murphy juice: the ratio of water=1:5 prepares murphy juice, by soil After beans add water, boil 30 minutes, after filter and remove residue, obtain murphy juice.
Preferably, after the raw material weighed being added seed culture vessel time prepared by seed culture medium, soil is added Fermented bean drink to the 30% of seed culture vessel volume, 121 DEG C, after sterilizing in 30 minutes and get final product.
Preferably, an activated spawn adds 10ml sterilized water and makes bacteria suspension, then is pressed by described bacteria suspension The volume ratio of 4%～8% is inoculated in seed culture medium, then at 250r/min, cultivates 24 under the conditions of 37 DEG C Bacillus subtilis YS-45 seed bacteria suspension is i.e. obtained after hour.
Preferably, in step B, according to the matter for producing the polypeptide vegetables each raw material of tailored version plant nutrient agent Amount number weigh other raw materials in addition to bacillus subtilis YS-45 seed bacteria suspension, by the dregs of beans weighed, Cotton dregs, brewex's grains, molasses, urea, inorganic salts, sodium selenite add in fermentation tank, then add water to send out The 70% of ferment tank volume, stirring mixing, sterilizing 30 minutes at 121 DEG C, press the volume ratio of 4%～8% after cooling Add bacillus subtilis YS-45 seed bacteria suspension, 250r/min, 37 DEG C, PH naturally under the conditions of Semi-finished product I are obtained after fermenting 48 hours.
The know-why of the present invention is: bacillus subtilis YS-45 fermentation makes cotton dregs, dregs of beans, brewex's grains etc. Breaks down proteins in material, generates multiple soluble polypeptide, is sprayed by tunning on vegetables, nutrition Peptide material in liquid is absorbed by vegetables and stores, thus improves the content of peptides in vegetables, simultaneously because inhale Receive sodium selenite, added the content of vegetables Organic Selenium, be finally translated into and human body is had health-care efficacy Organic Selenium, after the vegetables that this mode plants out are eaten by human body, the material such as polypeptide therein, Organic Selenium It is absorbed by the body.
Advantages of the present invention and beneficial effect: the present invention can increase the content of peptides in vegetables, can be by human body Directly absorb, improve the immunity of human body, regulation metabolism, promote the formation of new cell, replace aging Cell perform physiological function play the effect delayed senility, add the ore deposits such as vegetables content of peptides, Organic Selenium Content of material, has health-care effect to human body.
