Description
【Technical field】
The invention belongs to feed addictive preparing technical field, and in particular to a kind of eel feed amylum adhesive.
【Background technology】
In recent years, as attention of the China to culture fishery, artificial feeding eel quickly grow, cultured area expand and
Increase of production is all quickly.With the popularization and raising of eel culture technology, requirement to feed quality also more and more higher, and eel
The quality of feed depends primarily on the quality of used raw material.Mainly there are fish meal, pre-gelatinized starch, paddy in the raw material of eel feed
The ratio of protein powder, yeast and compound additive etc., wherein fish meal and pre-gelatinized starch is very big, and both sums often account for whole raw materials
80%-90%, wherein pre-gelatinized starch dosage are up to 20%-25%.
Pre-gelatinized starch plays adhesive effect in feed, is one of indispensable additive in eel feed production.Eel
Basic demand of the fish meal to amylum adhesive is cold water solubles (convenient use).In addition to above-mentioned requirements, also particular/special requirement：
Aquation swelling rate is fast；Ductility is good；Screen resilience is big；Ageing resistance is good.In recent years, Fujian, Guangdong, Jiangsu, Zhejiang etc. saved
Eel industry fast development is raised, promotes the development of eel feed industry, it is also increasing to the demand of pre-gelatinized starch.
As China's Coastal Areas fresh water supports the fast development of eel cause, higher want is proposed to the quality of eel feed
Ask.Past eel feed, mainly based on external import, and domestic eel feed in feed efficiency and viscoplasticity with foreign countries
Compared to still having certain gap, wherein eel feed binding agent --- the viscoplasticity deficiency of pre-gelatinized starch is one of major reason.
The pre-gelatinized starch quality better of import, steady quality, but it is on the high side.Also there is the preferable pre-gelatinized starch life of some quality the country
Producer is produced, but it is few in number.At present, the difference of domestic pre-gelatinized starch and the high-quality pre-gelatinized starch of import mainly shows
：Domestic pre-gelatinized starch elasticity is weak；The good aquation swellability of pre-gelatinized starch requirement and viscosity stability, to ensure eel material
Group does not scatter and disappear in water, and domestic pre-gelatinized starch is generally inferior to import powder.Therefore, develop that bonding force is strong, viscoplasticity is high, anti-
The pre-gelatinized starch that aging is good, aquation swelling rate is fast has great importance.
【The content of the invention】
The present invention provides a kind of eel feed amylum adhesive, to solve existing eel feed amylum adhesive elasticity
The problems such as weak, aquation swellability and viscosity stability difference.The present invention will be grafted, be crosslinked a variety of denaturation methods and pre-gelatinized method knot
Altogether, make eel feed amylum adhesive that there is multidimensional network structure, it is more preferable to assign eel feed amylum adhesive
Film forming, caking property, ageing resistance；The present invention eel feed amylum adhesive can improve stability of the feed in water and
The utilization rate of feed, the loss for reducing feed nutrient, mitigate the pollution to breeding environment.
To solve above technical problem, the present invention uses following technical scheme：
A kind of eel feed amylum adhesive, it is using tapioca as raw material, passes through elder generation and ethyl acetate, acrylamide
Reacted, then carry out cross-linking reaction with sodium hydroxide and epoxychloropropane, then carry out pre-gelatinized reaction, finally dried, powder
Broken, sieving obtains eel feed amylum adhesive.
Preferably, after tapioca first being made into the slurry that concentration is 20-21Be ', then enter with ethyl acetate, acrylamide
Row reaction.
Preferably, the concentration of the ethyl acetate is 0.5%-0.8%.
Preferably, the reaction and the cross-linking reaction are the stirring reaction 0.5-1h under the conditions of temperature is 28-35 DEG C
Carry out.
Preferably, the rotating speed of the stirring is 50-80r/min.
Preferably, the drying machine is cylindrical drier.
Preferably, the temperature of the drying is 150-160 DEG C.
Preferably, the sieve of the sieving is 60-80 mesh.
Preferably, the eel feed is 5%-7% with the water content of amylum adhesive.
The invention has the advantages that：
(1) present invention will be grafted, be crosslinked a variety of denaturation methods and pre-gelatinized method combines, and make eel feed starch
Adhesive has multidimensional network structure, assigns the more preferable film forming of eel feed amylum adhesive, caking property, ageing resistance；
(2) index such as eel feed amylum adhesive cold water soluble, caking property, retentiveness and stability of the invention
It is good；
(3) eel feed amylum adhesive of the invention can improve the utilization of stability and feed of the feed in water
Rate, the loss for reducing feed nutrient, mitigate the pollution to breeding environment.
