Abstract
The invention discloses starch adhesive used for sea eel feedstuff and belongs to the technical field of feedstuff additive preparation.With cassava starch being a raw material, a cross-linking graft reaction is performed among the cassava starch, ethyl acetate and acrylamide, then a cross-linking reaction is performed among the cassava starch, sodium hydroxide and epoxy chloropropane, then a pregelatinization reaction is performed, and finally the starch adhesive used for the sea eel feedstuff is obtained through drying, smashing and sieving.The graft and cross-linking denaturation methods are combined with the pregelatinization method, so that the starch adhesive used for the sea eel feedstuff is of a multi-dimensional net-shaped structure and is endowed with a better film-forming property, better adhesion and better anti-aging performance; the starch adhesive used for sea eel feedstuff can improve the stability of the feedstuff in water and increase the utilization rate of the feedstuff, reduce the loss of feedstuff nutrients and reduce pollution to a breeding environment.
Description
[technical field]
The invention belongs to feed additive preparing technical field, be specifically related to a kind of eel feed amylum adhesive.
[background technology]
In recent years, along with China's attention to culture fishery, artificial breeding Anguillar japonica quickly grows, cultured area expand and increase of production all quickly.Along with the universal of eel culture technology and raising, the requirement of feed quality is also more and more higher, and the quality of eel feed depends primarily on the quality of adopted raw material.The raw material of eel feed mainly has fish flour, pre-gelatinized starch, gluten meal, yeast and compound additive etc., wherein the ratio of fish flour and pre-gelatinized starch is very big, both sums often account for the 80%-90% of whole raw material, and wherein the consumption of pre-gelatinized starch is up to 20%-25%.
Pre-gelatinized starch plays adhesive effect in feedstuff, is one of indispensable additive during eel feed produces.The basic demand of amylum adhesive is cold water solubles (convenient use) by eel feed.Except above-mentioned requirements, also has particular/special requirement: aquation swelling rate is fast；Ductility is good；Resilience force is big；Ageing resistance is good.In recent years, Fujian, Guangdong, Jiangsu, Zhejiang etc. were economized and were raised eel industry fast development, had promoted the development of eel feed industry, and the demand of pre-gelatinized starch is also increasing.
Along with China's Coastal Areas fresh water supports the fast development of eel cause, the quality of eel feed is had higher requirement.The eel feed in past, mainly based on external import, and domestic eel feed still has certain gap in feed efficiency and viscoelasticity compared with abroad, and wherein the viscoelasticity deficiency of eel feed binding agent pre-gelatinized starch is one of major reason.The pre-gelatinized starch quality better of import, steady quality, but on the high side.Domestic also have the good pre-gelatinized starch manufacturer of some quality, but few in number.At present, domestic pre-gelatinized starch is mainly manifested in the difference of the pre-gelatinized starch of the high-quality of import: domestic pre-gelatinized starch elasticity is weak；Pre-gelatinized starch requires good aquation swellability and viscosity stability, and to ensure that eel dough is not scattered and disappeared in water, and domestic pre-gelatinized starch is generally inferior to import powder.Therefore, develop the pre-gelatinized starch that bonding force is strong, viscoelasticity is high, ageing resistance is good, aquation swelling rate is fast to have great importance.
[summary of the invention]
The present invention provides a kind of eel feed amylum adhesive, to solve that existing eel feed amylum adhesive elasticity is weak, the problem such as aquation swellability and viscosity stability difference.The present invention by grafting, cross-link multiple denaturation method and pre-gelatinized method combines, make eel feed amylum adhesive have multidimensional network structure, give the better film property of eel feed amylum adhesive, caking property, ageing resistance；The eel feed amylum adhesive of the present invention can improve the utilization rate of feedstuff stability in water and feedstuff, reduce the loss of feed nutrient, alleviates the pollution to breeding environment.
For solving above technical problem, the present invention by the following technical solutions:
A kind of eel feed amylum adhesive, it is with tapioca for raw material, cross-linked graft reaction is carried out with ethyl acetate, acrylamide by elder generation, then cross-linking reaction is carried out with sodium hydroxide and epoxychloropropane, carry out pre-gelatinized reaction again, final drying, pulverize, sieving obtains eel feed amylum adhesive.
Preferably, after first tapioca being made into the slurry that concentration is 20-21Be ', then carry out cross-linked graft reaction with ethyl acetate, acrylamide.
Preferably, the concentration of described ethyl acetate is 0.5%-0.8%.
Preferably, the reaction of described cross-linked graft and described cross-linking reaction are all that under 28-35 DEG C of condition, stirring reaction 0.5-1h carries out in temperature.
Preferably, the rotating speed of described stirring is 50-80r/min.
Preferably, described drying machine is cylindrical drier.
Preferably, described dry temperature is 150-160 DEG C.
Preferably, the sieve sieved described in is 60-80 order.
Preferably, the water content of described eel feed amylum adhesive is 5%-7%.
The method have the advantages that
(1) present invention by grafting, cross-link multiple denaturation method and pre-gelatinized method combines, make eel feed amylum adhesive have multidimensional network structure, give the better film property of eel feed amylum adhesive, caking property, ageing resistance；
(2) eel feed of present invention amylum adhesive cold water soluble, the index such as caking property, retentiveness and stability is good；
