Abstract
The invention discloses a complex antioxidant and a preparation method thereof. The complex antioxidant is prepared by using the following components by weight percent: 2-66 percent of ethoxyquinoline, 2-50 percent of dibutylhydroxytoluene, 1-40 percent of citric acid, 1-33 percent of white carbon black and 10-80 percent of calcium carbonate. The preparation method comprises the steps of: (1) weighing the components according to the formulation proportion, spraying ethoxyquinoline to a mixture of white carbon black and calcium carbonate, and stirring while spraying; and (2) uniformly mixing and stirring the mixture subjected to stirring and spraying with the other remained components. The complex antioxidant prepared by using the method has the advantages of high comprehensive effectiveness, good antioxidation effect, high safety, low preparation cost and the like, is long in lasting effect after a small quantity of complex antioxidants is added, and is suitable for popularization and application on additives.
Description
Technical field
The present invention relates to food or field of feed additive technology, be specifically related to a kind of composite antioxidant and preparation method thereof.
Background technology
Prior art is used for the anti-oxidant of food or feed addictive, and general antioxidant effect is poor, and anti oxidation time is short, and effect is not very desirable, and security is not high.Like ethoxyquinoline (claiming EMQ again); Be to use one of extensive, the most most economical anti-oxidant kind both at home and abroad; It is a kind of quinoline with antioxidant effect,, is processed into pulvis with carrier usually and uses to light brown thick liquid for amber; Its antioxygenic property is stronger, and is especially more effective to the protection of vitamin.But the action effect of this single anti-oxidant is limited, add in food or the feed after, its antioxidant effect just lost efficacy at short notice.If just must strengthen its addition in order to reach desirable antioxidant effect; Can cause cost to increase so on the one hand; Color and luster owing to ethoxyquinoline self changes too soon, too greatly on the other hand; During a large amount of the use food or premix color and luster are sharply deepened, be mistaken as food or quality of the fodder changes, this is the shortcoming of this product; Also be to be reluctant too much to add the major reason of ethoxyquinoline in food or the feed, and excessive interpolation can influence the safety in utilization of food or feed.In addition, ethoxyquinoline is also not satisfactory to the antioxidant effect of some grease.
And for example dibutyl hydroxy toluene (claiming BHT again) owing to cheap, also is one of anti-oxidant kind of using always.Dibutyl hydroxy toluene is a white crystals, because its molecular structure parent is a phenol, phenol is not too safe additive, and therefore use amount has certain restriction in food or feed.
Summary of the invention
The present invention is directed to the above-mentioned deficiency of prior art, provide a kind of have the height of comprehensively tiring, good, a small amount of interpolation of antioxidant effect just can be effective for a long time, safe, the composite antioxidant of advantage such as cost of manufacture is low.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of composite antioxidant, by each component preparation 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%.
As preferably, described composite antioxidant is by each component preparation of following percentage by weight: ethoxyquinoline 6～48%, dibutyl hydroxy toluene 4～24%, citric acid 2～20%, white carbon 8～30%, calcium carbonate 25～60%.
Preferred as further, described composite antioxidant is by each component preparation of following percentage by weight: ethoxyquinoline 20%, dibutyl hydroxy toluene 6%, citric acid 4%, white carbon 10%, calcium carbonate 60%.
As preferably, described dibutyl hydroxy toluene, citric acid, white carbon and calcium carbonate grinding particle size are through 40 mesh sieves.
The present invention also provide a kind of above-mentioned composite antioxidant the preparation method, preparation process is following:
(1) takes by weighing each component according to formula rate, then ethoxyquinoline is sprayed onto on the mixture of white carbon, calcium carbonate, stir while spraying;
(2) will spray mixture after being mixed and other remaining ingredient mixing and stirring get final product.
As preferably, the temperature of described ethoxyquinoline in the sprinkling process is controlled to be 20～80 ℃, increasing the flowability of ethoxyquinoline, thereby can guarantee to spray more smooth and easy, even.Advantage of the present invention and beneficial effect:
1. composite antioxidant of the present invention has the height of comprehensively tiring, the antioxidation time is long, cost of manufacture is low (be original cost half the below), if same cost then comprehensively tire will be up to 5～6 times.The particularly adding of citric acid in the prescription, one, the citric acid low price, and belong to food grade additives, so safer; In addition, what is more important, citric acid can with the prescription in each oxidation-resistant active ingredient effect; Make each oxidation-resistant active ingredient with effect back inefficacy such as grease regain reduction; Thereby participate in antioxidation once more, play a purpose of recycle repeatedly, therefore; Having prolonged the antioxidation time of composite antioxidant greatly, is 5～6 times of action time of original single use ethoxyquinoline.
2. the security of its use of composite antioxidant of the present invention is much higher than the anti-oxidant of single variety, and its reason is to reach under the prerequisite of same antioxidant effect, and the use total concentration in the composite antioxidant is lower than the antioxidant concentration of single variety.
3. composite antioxidant of the present invention will be wherein the grinding particle size of solid material limit and can pass through 40 mesh sieves, thereby the refinement raw material particle size, it is more even to make that each raw material mixes, the active area increase, thereby effectively guaranteed the result of use after compound.
4. the preparation method of composite antioxidant of the present invention; At first ethoxyquinoline is sprayed onto on the mixture of white carbon, calcium carbonate; Stir while spraying; Thereby make the ethoxyquinoline of oily fully be distributed to the surface of the mixture of white carbon, calcium carbonate, and then mixture and other raw materials fully mixed, thus than directly with ethoxyquinoline mix with other raw material stirring more even; And, guaranteed effectively that also mixed process does not stick together between each raw material, agglomeration, thereby made that the result of use of each raw material is farthest improved.
