Description
Technical field
The present invention relates to a kind of method utilizing corn straw to prepare mixed feed sweeting agent, belong to technique for producing feed neck
Territory.
Background technology
Numerous studies show, " the first factor " that affect young stock production performance is to search for food.Arbitrarily searching for food of young stock is the lowest
Requirement in maximum potential produtivity.Accordingly, it is capable to the no productive potentialities playing young stock, it is critical only that and can improve feed intake.From
Since the eighties in last century, domestic and international numerous studies show, add sweeting agent and can significantly improve young stock feed intake, change in feedstuff
Kind breeding performonce fo animals.
Nowadays sucrose safety is high, and energy is high, and in good taste, its addition in some young stock daily ration may be up to 2%.But
Being in most modern Feed Manufacturing, add a large amount of sucrose to improve feed intake in feedstuff, its cost is excessively really
Expensive.The sugariness of saccharin sodium is 300～500 times of sucrose, and cheap, stable performance is generally adopted at feedstuff industry
With so far.But its taste matter is poor, obvious metallic aftertaste and safety is had to be constantly subjected to dispute.
And neotame addition is only the 1/20 of saccharin sodium, use the safest in feedstuff.Its cost is similar to saccharin sodium,
But less than saccharin sodium compound sweetener.But the sugariness of neotame is the highest, feedstuff per ton only needs to add 0.2～0.5g, directly adds
In feedstuff, it is difficult to mix homogeneously, cause feedstuff local flavor inconsistent, reduce the feed intake of animal on the contrary.Additionally due to addition
Little, in adding procedure, the loss of powder is the biggest for addition, loss amount account for total addition level can reach 10～
30%, also can reduce its using effect.Therefore, neotame application in feedstuff is limited.
Summary of the invention
The technical problem to be solved: poor as sweeting agent taste matter for saccharin sodium, has more than obvious metal
Taste and safety are the highest, and neotame sugariness is the highest, it is difficult to mix homogeneously, the problem limiting neotame application in feedstuff, carry
Supply a kind of with corn straw as main raw material(s), after the corn straw being cut into segment is mixed with ethanol and vibrates, extruding, will
Effluent is standby, and is mixed with the material such as Herba Eichhorniae, Semen Ricini by extruding residue, and carries out high-temperature high-voltage reaction, and discharging is cold
After freezing, by itself and standby effluent, seafood mushroom mixed grinding, abrasive material is fermented and extrudes, by squeezed fluid and hargil
After stirring mixing, add ethanol, stand and filter, filtrate is dried, the method that mixed feed sweeting agent can be prepared into.The present invention
The sweeting agent taste matter of preparation is preferable, and sugariness is moderate, can significantly improve animal feed intake, wherein without metallic aftertaste, and safety
Property is higher.
For solving above-mentioned technical problem, the present invention uses the technical scheme as described below to be:
(1) take fresh corn straw, use chopper to be cut into the segment of a length of 2～3cm, then by solid-to-liquid ratio 1:2～4, will
The segment cut is that 30% ethanol solution is mixed homogeneously with mass fraction, is placed in ultrasonator, under 24～26KHz
Vibration 10～15min, is subsequently placed in extruder, extrudes with 7～9MPa, until no liquid flows out, collects effluent, standby
With；
(2) count by weight, take residue in 40～50 parts of above-mentioned extruders, 22～26 portions of Herba Eichhorniae, 10～14 portions of Semen Ricinis
And 5～7 parts of mass fractions are the sodium carbonate liquor of 40%, stirring, put in autoclave, controlling temperature of reaction kettle is
80～90 DEG C, and reactor is boosted to 3～4MPa, keep pressure 20～30min, in 1～3min, be depressurized to standard subsequently
Atmospheric pressure, naturally cools to room temperature；
(3) above-mentioned be cooled to room temperature after carry out discharging, discharging thing is placed in the refrigerator of-10～0 DEG C freezing 3～4h, then will
Frozen material is put in pulverizer and is pulverized, and crosses 150 mesh sieves, is pressed by effluent standby to granule and the step (1) of the gained that sieves
Solid-liquid 1:3～5 mix homogeneously, then by mixture and seafood mushroom in mass ratio 4～5:1, put into grinding machine for grinding 4～6min；
(4) putting in fermentation tank by abrasive material after above-mentioned grinding terminates, addition is the 30～40% of fermentation tank capacity, sets
Temperature is 24～26 DEG C, with 100r/min stirring fermentation 2～4 days, then is put in extruder by the fermenting mixture in fermentation tank
Extrude, until no liquid flows out, collect effluent and its quality 6～8% hargil put into magnetic force and stir in machine, with 120r/
Min stirring 4～5h, adds effluent volume 80～the dehydrated alcohol of 90% subsequently, filters after standing 30～40min,
Collect filtrate, be spray-dried, collect dried object, i.e. can get mixed feed sweeting agent.
The application process of the present invention: the mixed feed sweeting agent of above-mentioned preparation is mixed with pig feed 1:90 in mass ratio
Closing, and stir it, controlling mixing speed is 130～160r/min, after to be mixed 30～40min, by mixing after stirring
Compound feeding piglet, every day, feeding volume was the 0.5 of pig body weight～after 0.8%, 10～13 day, and daily gain in pigs improves 13～15%, adopts
Appetite improves 10～14%.
The present invention is compared with additive method, and Advantageous Effects is:
(1) the sweeting agent taste matter that prepared by the present invention is preferable, and sugariness is moderate, can significantly improve animal feed intake；
(2) sweeting agent prepared by the present invention is wherein without metallic aftertaste, and safety is higher；
(3) preparation process of the present invention is simple, required low cost.
