Abstract

The invention discloses a protein enveloped milk cow feed and a preparation method thereof. The feed is prepared from the following raw materials in parts by weight (Kg): 60-70 parts of corn flour, 10-15 parts of cassava residues, 5-8 parts of gypsum powder, 80-100 parts of rice bran and fresh forage, 15-20 parts of rapeseed meal, 3-5 parts of agar powder, 1-2 parts of citric acid, 5-7 parts of iodised salt, 10-15 parts of protein enveloping agent and a proper amount of water. The feed is particularly a protein enveloped feed prepared by using fresh forage and corn flour as main raw materials, and has the advantages that the protein envelop has more nutritional value, the main materials are finely processed, the nutrition-allocated proportion is balanced, and the flavor accords with the smell of milk cow. The smell on the protein enveloped feed can be preserved for a longer time, and the preservation period of the feed can be prolonged.

Description

A kind of protein film coating milk cow forage and preparation method thereof

Technical field

The invention belongs to the work technical field of feed, be specifically related to a kind of protein film coating milk cow forage and preparation method thereof.

Background technology

Edible packing membrane is if polysaccharide or protein are for raw material with edible natural material, by the film with porous network structure that the interaction between different molecular is formed, by preventing gas, the migration of steam and solute etc. keeps the quality of food, extend shelf time, compared with synthesising packing material, edible film can be biodegradable, without any pollution, can also as flavour of food products agent, nutrition fortifier is particularly that the edible film of base-material has certain nutritive value with protein, the features such as the good permeability of mouthfeel is little.

Along with the application of mixed feed and perfect, trophic component science and the balance increasingly of feed, but more and more lose the natural flavour mountaineous of feed, cause the allure of the palatability of feed product and feed intake worse and worse.As everyone knows, no matter people or animal, food nutrition, feed intake and digestion amount be keep fit growth, play 3 fundamentals of maximum productivity.If can not enoughly ingest and digest and assimilate, the nutrition in food or feed be how also of no avail again.Therefore, how to improve digesting and assimilating of feed targetedly, improve feed local flavor, in future in feed industry, there is huge development potentiality.

Summary of the invention

The present invention is low according to milk cow forage nutrient utilization, long-time storage is perishable, and the easy conglomeration flavor effect of feed itself distributes the problems such as too fast, a kind of convenient storage of preparation, the time of putting deposits flavor effect still and coating has the protein film coating milk cow forage of nutritive peculiarity, and concrete grammar is as follows:

A kind of protein film coating milk cow forage, it is characterized in that, be made up of the raw material of following weight portion: corn flour 60 ~ 70, manioc waste 10 ~ 15, land plaster 5 ~ 8, rice bran, fresh forage 80 ~ 100, rapeseed dregs 15 ~ 20, agar powder 3 ~ 5, citric acid 1 ~ 2, salt compounded of iodine 5 ~ 7, protein envelope agent 10 ~ 15 and appropriate water;

Described protein envelope agent is made up of the raw material of following weight portion: glycerine 4 ~ 6, sorbierite 0.5 ~ 1, carboxymethyl cellulose 1 ~ 2, soy meal 70 ~ 80, sodium acid carbonate 20 ~ 30, cyclodextrin 10 ~ 15, the porous peat composed of rotten mosses 2 ~ 3 and appropriate water; Soy meal is crossed 100 mesh sieves to obtain fine powder by preparation method, then dissolve each other with water and be heated to 60 DEG C of stirring and dissolving, adding sodium acid carbonate regulates pH to be 8 ~ 9, constant temperature leaves standstill 30min, then remove top layer oil stain and scum silica frost, remainder centrifuging and taking is precipitated, then adds glycerine, sorbierite, carboxymethyl cellulose, cyclodextrin and the porous peat composed of rotten mosses, add water in right amount and stir into the pasty state of thickness, be incubated for subsequent use;

A preparation method for protein film coating milk cow forage, is characterized in that, comprises following step:

(1) pulverized by droplet-shaped pulverizer after fresh forage, manioc waste and rapeseed dregs being mixed, rough residue is obtained after crossing sieve aperture, mixing rice bran, corn flour, agar powder, citric acid, salt compounded of iodine and other following residual components do not related to again, the adjustment water yield 50% that adds water makes feedstuff;

(2) integrated by feed quality-adjusting device by the feedstuff described in (1), control vapor (steam) temperature 100 ~ 120 DEG C, rotating speed 300 ~ 350r/min continues 30 ~ 50min, obtains the slurry of even gelatinization after completing, granulation after adjustment water content 30%;

(3) protein envelope agent magnetic stirrer is held, adjustment rotating speed 200r/min, then the overall microwave treater effect 2 ~ 3min putting into 300 ~ 400W power, after completing, in coating machine, the feed granules of even application described in (2) is surperficial, and simple grain feed spraying total amount is 5 ~ 8% of simple grain total amount;

(4) feed granules after (3) being completed to proceed in the thermostatic drying chamber of 50 ~ 60 DEG C after dry 12h.

Protein envelope agent of the present invention is by glycerine, sorbierite, carboxymethyl cellulose, soy meal, sodium acid carbonate, cyclodextrin and porous peat composed of rotten mosses composition, soybean is selected to be there is a large amount of hydrogen bonds in soybean protein molecule, hydrophobic bond and ionic bond etc., soybean protein is made to have good filming performance, take soyabean protein powder as main matrix, be 8 ~ 9 by adding a certain amount of sodium acid carbonate adjusted to ph, the most protein active ingredient of Precipitation, lipid part and the residue on top layer are removed in drift, obtain the soybean protein mixing portion that purity is slightly high, then interpolation glycerine and sorbierite are as plasticizer, carboxymethyl cellulose is as crosslinking agent, can be made into and there is good strength, the edible film of elasticity and moisture resistance feature, there is maintenance moisture, tissue oxygen air infiltration enters, edible nourishing is worth high, the multiple advantages such as the original local flavor of material can also be kept, add the porous peat composed of rotten mosses and cyclodextrin, all be conducive to adsorbing flavor substance, protein film acts on the top layer of feed after all, directly and milk cow oral contact, cyclodextrin and the porous peat composed of rotten mosses have the effect of absorption smell, there is the effect that the local flavor making feed is preserved for a long time.

After the present invention show that another novelty progress is to utilize the microwave treatment action protein film material composition 2 ~ 3min of 300 ~ 400W power by experiment, oxygen transmission rate, the permeability rate of the finished product protein film made decrease, and mechanical strength increases, improve the practical ability of edibility protein film further.

Experimental data shows: the light transmittance impact of the soybean protein film after microwave treatment is little, but can obviously observe out oxygen transmission rate and reduce about 60%, and permeability rate also has the reduction of corresponding 15 ~ 20%, action effect is obvious, and film appearance uniform is without visible micropore.

Visible protein raw material is after the effect process of microwave, more even between each composition, eliminates the repulsive interaction between only a few polar bond, reaches the effect of the idealized coordinating and unifying, to making film forming uniform and smooth more, outstanding in mechanical tenacity and permeability.Following table is the comparison of protein envelope hot strength before and after process, and after obviously finding out process, the mechanical strength of coating is strengthened.

Microwave treatment is on the impact of film mechanical performance

Advantage of the present invention: the present invention with fresh forage and corn flour for primary raw material makes a kind of feed of protein envelope, protein envelope has more nutritive value, major ingredient retrofit, nutrition-allocated proportion is balanced, taste agrees with the sense of smell of milk cow, and the feed of protein envelope, the smell holding time on surface is more permanent, and the shelf-life of feed extends to some extent.
