Problems solved by technology

Dibutyl hydroxytoluene is a white crystal. Since its molecular structure is phenol, phenol is an unsafe additive, so its usage in food or feed is limited to a certain extent.
In addition, the above-mentioned antioxidants are mainly aimed at the anti-oxidation of animal fat, so they have a single effect and a narrow range of applications

Embodiment 1

[0022] (1) Take each component according to the following formula: ethoxyquinoline 22%, dibutylhydroxytoluene 8%, tert-butyl hydroquinone 4%, citric acid 6%, white carbon black 10%, carbonic acid Calcium 50%.

[0023] (2) Ethoxyquinoline is heated to 30 ℃ and sprayed onto the mixture of white carbon black and calcium carbonate, stirring while spraying;

[0024] (3) Stir and mix the sprayed and stirred mixture with the remaining dibutyl hydroxytoluene, tert-butyl hydroquinone and citric acid evenly.

[0025] Add the above-mentioned composite antioxidant to the feed, the addition amount is 0.0125-0.05%, and it can be stored for 6-12 months at normal temperature; when it is added to the moon cake, the addition amount is 0.25%, and it can be stored for 2-6 months at normal temperature. However, with a single ethoxyquinoline antioxidant, the same addition amount can only be stored for 15 to 30 days at room temperature, and rancidity will appear.

Embodiment 2

[0027] (1) Weigh each component according to the following formula: ethoxyquinoline 12%, dibutylhydroxytoluene 14%, tert-butylhydroquinone 2%, white carbon black 8%, calcium carbonate 64%.

[0028] (2) Ethoxyquinoline is heated to 40 ℃ and sprayed onto the mixture of white carbon black and calcium carbonate, stirring while spraying;

[0029] (3) Stir and mix the sprayed and stirred mixture with the remaining dibutyl hydroxytoluene and tert-butyl hydroquinone evenly.

[0030] Add the above-mentioned composite antioxidant to the feed, the addition amount is 0.0125-0.05%, and it can be stored for 6-12 months at normal temperature; when added to the moon cake, the addition amount is 0.4%, and it can be stored for 3-5 months at normal temperature. However, with a single ethoxyquinoline antioxidant, the same addition amount can only be stored for 15 to 30 days at room temperature, and rancidity will appear.

Embodiment 3

[0032] (1) Take each component according to the following formula: ethoxyquinoline 36%, dibutylhydroxytoluene 4%, tert-butyl hydroquinone 3%, citric acid 4%, white carbon black 12%, carbonic acid Calcium 41%.

[0033] (2) Then ethoxyquinoline is heated to 30 ℃ and sprayed onto the mixture of white carbon black and calcium carbonate, stirring while spraying;

[0034] (3) Stir and mix the sprayed and stirred mixture with the remaining dibutyl hydroxytoluene, tert-butyl hydroquinone and citric acid evenly.

[0035] Add the above-mentioned compound antioxidant to the feed, the addition amount is 0.0125-0.05%, and it can be stored for 6-12 months at normal temperature; when it is added to the moon cake, the addition amount is 0.15%, and it can be stored for 3-5 months at room temperature. However, with a single ethoxyquinoline antioxidant, the same addition amount can only be stored for 15 to 30 days at room temperature, and rancidity will appear.

Abstract

The invention discloses a complex antioxidant and a preparation method thereof. The complex antioxidant is mainly prepared by using the following components by weight percent: 2-66 percent of ethoxyquinoline, 2-50 percent of dibutylhydroxytoluene, 0.5-30 percent of tertiary butyl hydroquinone, 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, wide application range and the like, is long in lasting effect after a small quantity of complex antioxidantsis added, and is suitable for popularization and application on additives.

Description

technical field [0001] The invention relates to the technical field of food or feed additives, in particular to a composite antioxidant and a preparation method thereof. Background technique [0002] Antioxidants used in food or feed additives in the prior art generally have poor antioxidative effect, short antioxidative time, unsatisfactory effect and low safety. For example, ethoxyquinoline (also known as EMQ), is one of the most widely used and most economical antioxidants at home and abroad. It is a quinoline derivative with antioxidant effect, which is amber to light brown and viscous. Liquid, which is usually processed into powder with a carrier, has strong antioxidant properties, especially for vitamin protection. However, the effect of this single antioxidant is limited, and its antioxidant effect will fail in a short time after being added to food or feed. If in order to achieve the ideal anti-oxidation effect, its addition amount must be increased, which will inc...
