Description
Technical field
The present invention relates to the technical field of animal feed additive, particularly relate to a kind of animal feed composite antioxidant and preparation method.
Background technology
Along with the continuous progress of feed industry, feed antioxidant have also been obtained significant progress.For a long time, people use synthetized oxidation preventive agent as BHT(dibutyl hydroxy toluene always), EMQ (ethoxyquinoline), BHA(butylated hydroxy anisole), TBHQ (butylhydroquinone) and PG(n-propyl gallate) etc., this kind of antioxidant is mainly oxidized in order to slow down the nutritional labeling such as vitamin, each lipid-like substances in feed, to ensure the freshness of feed and to improve the price of deed, but synthetized oxidation preventive agent easily decomposes, effect is low, irritant, toxicity and carcinogenesis.Such as, the most widely used ethoxyquinoline in feed antioxidant raw material, if addition is too much, can causes " yellow fat meat ", cause meat safety problem, affect the physical and mental health of consumer.
Biogenic antioxidant is the antioxidizing agent extracted from plant or microorganism; at present from independent anti-oxidant for grease and oil-containing feed; develop into the scavenger as oxygen radical in body, the cell tissue that watches for animals, protection vascular circulation, the anticancer and physiological action such as to delay senility can be played.At present, mainly carotenoid is comprised at the biogenic antioxidant of research, plant polyphenol is (as Tea Polyphenols, comprise flavanol compound, anthocyanin class, flavonoids, flavonols and phenolic acid class etc., removing harmful free radicals that can be extremely strong, block lipid peroxidation process, improve the activity of animal body endoenzyme, thus play enhancing disease resistance of livestock and poultry, improve effect of Animal product quality), active polysaccharide (as algal polysaccharides), vitamins is (as VE, VC and derivative thereof), enzyme, phytoprotein, polypeptide, amino acid, microbial origin antioxidant is (by lactic acid bacteria, the fermentable such as bacillus and saccharomycete, containing multiple antioxidant content, the animal tissue lesion that oxidative stress causes can be alleviated, improve production performance and the reproductive performance of animal).The application of biogenic antioxidant on feed shows as the preservation effect improving feed, by anti-oxidant in body, improve the immunity function of animal and improves the aspects such as meat, by substituted chemistry synthetized oxidation preventive agent.
The most of feed antioxidant of tradition adopts simple pulverizing (Crushing of Ultrafine or ultramicro grinding), hybrid mode is produced, the inferior position of this production: pulverize the material particles produced not of uniform size, during mixing, each component certainly leads to larger separation, can not be uniformly distributed, final products real composition ratio and formula rate have relatively large deviation, and each component can not effectively play a role.The product antioxidant effect variation that different batches is even same batch is larger.
The patented technology about feed antioxidant announced at present is generally after EMQ (ethoxyquinoline) carrier (corncob, diatomite, white carbon or white bole etc.) absorption, then with BHT(dibutyl hydroxy toluene), BHA(butylated hydroxy anisole), TBHQ (butylhydroquinone) and PG(n-propyl gallate) etc. raw material mix together.The patent No. be 201210091935.6 Chinese patent disclose a kind of composite antioxidant and preparation method thereof, this antioxidant is prepared by each component of following percentage by weight: ethoxyquinoline 2 ~ 66%, dibutyl hydroxy toluene 2 ~ 50%, citric acid 1 ~ 40%, white carbon 1 ~ 33%, calcium carbonate 10 ~ 80%.Preparation process is: (1) takes each component according to formula rate, is then sprayed onto by ethoxyquinoline on the mixture of white carbon, calcium carbonate, and sprinkling limit, limit is stirred; (2) mixture after stirring and other remaining ingredient mixing and stirring will be sprayed.Although the composite antioxidant that this invention obtains has the advantages such as security is high, cost of manufacture is low, each component can not be uniformly distributed well, and between product batches, antioxidant effect is unstable.
In view of this, the present inventor studies and devises a kind of animal feed composite antioxidant and preparation method, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of animal feed composite antioxidant, by select biogenic antioxidant and chemical synthesis antioxidant composite, effectively can play the complementary effect of biogenic antioxidant and chemical synthesis antioxidant, while reducing costs, turn improve antioxidant effect.
