Adding citric acid has a certain synergistic effect on TBHQ antioxidant activity.

The order of antioxidant activity in soybean oil is TBHQ>Vc>VE>catechins>BHT. Among them, TBHQ, VE, and BHT have good oil solubility and do not change color after heating, making them suitable for use as advanced soybean oil antioxidants. The antioxidant effect of BHT can only be displayed after a long time. Adding 20mg/kg to oil for short-term storage is better than adding 100mg/kg. Although Vc and catechins have strong antioxidant effects, they are difficult to dissolve in oil and have poor thermal stability.

When the oil contains a large amount of metal ions and oxygen, the addition of antioxidants can inhibit the formation of peroxides. When citric acid is combined with antioxidants, the higher the content of these impurities in the oil, the more obvious the synergistic effect. TBHQ has good oil solubility and thermal stability, and does not change in color after heating.The process of adding oil is complex, and it is easy to precipitate or oxidize during placement. Therefore, they should not be used as advanced oil antioxidants.

 It plays an irreplaceable role in the production process of pastry food and is also an important source of energy for consumers. However, the oxidation and rancidity of fats and oils, as well as the production of unpleasant flavors, are a problem that troubles many pastry food producers. They not only cause changes in the appearance, taste, and odor of pastry food, but also affect the length of its shelf life. Adding food antioxidants is the most convenient, feasible, and effective method.Pastry is generally made from grains, oil, sugar, and/or sweeteners, eggs, milk, etc.

With the development of farming and pet industry, the market demand for feed is increasing day by day, feed antioxidant TBHQ into the people's vision.1.Product ParametersMolecular formula: C10H14O2Molecular weight: 166.22CAS No.: 1948-33-0The experimental results show that adding 002% TBHQ to oil can increase the antioxidant stability of the tested oil by 2-5 times, thus extending the shelf life of oil based foods compared to adding traditional antioxidants; And the antioxidant effect increases with the increase of the addition amount; The use of a small amount of synergist in combination

Antioxidants are substances that prevent or delay food oxidation, improve food stability, and extend storage life.Food antioxidants can be divided into oil-soluble antioxidants and water-soluble antioxidants based on their solubility properties.Oil soluble antioxidants can be soluble in fats and oils, and have a good antioxidant effect on fats and fatty foods, preventing their oxidation, rancidity, and oil burning. Commonly used include butyl ether, dibutyl light toluene, gallic acid propionic acid vinegar, etc.TBHQ may volatilize faster than BHT.

In view of the advantages of TBHQ and BHT, in recent years, BHT and TBHQ have become widely used antioxidants in fats and oil-rich foods . It should be pointed out that TBHQ and BHT have small molecular weights, are volatile and easy to sublimate, and under heating conditions, both volatilization and depletion are relatively fast, and the antioxidant performance will be generated through a series of complex redox reactions to produce the corresponding transformation products.

The main cause of food deterioration during processing, transportation and storage is lipid oxidation, and the addition of antioxidants is the main means of delaying the oxidation of oil and fat products. Antioxidant is a free radical trapping agent, when it plays an antioxidant role, it can provide active hydrogen to combine with free radicals generated during oxidation of fats and oils, so that the free radicals are converted into stable compounds, blocking the free radical chain reaction, inhibiting lipid peroxidation, slowing down the oxidation of fats and oils and deterioration.

Product Parameters：Lard antioxidant TBHQ is white to light grey crystalline or crystalline powder, with very slight special smell, soluble in ethanol, acetic acid, ethyl alcohol, isopropyl alcohol, ethyl alcohol and oil, etc., a few are insoluble in water (25 ℃ <1%: 95 ℃ ﹤ 5%) TBHQ is a kind of oil-soluble antioxidant, which can prevent or prolong the oxidation of oil and fat deterioration in food.Product Applications：At present, the most commonly used antioxidants in fats and oils and their products are BHA, BHT, PG, TBHQ and tocopherol.

Product DescriptionIn addition, TBHQ also has characteristics such as high temperature resistance, oil solubility, and antibacterial properties, which are widely used in edible oils, fried foods, etc. By comparing the effects of various antioxidants in different products, summarizing the usage patterns, and providing theoretical basis for the application of TBHQ.The oil in oily food undergoes oxidation in the air, producing free radicals and peroxides, which are early indicators of food rancidity.

Pastry and bread stored in the air for a long time are prone to spoilage due to oxidation of their lipid components. The oxidation of oil components not only causes food discoloration, discoloration, destruction of vitamin A, D, E, and other components, but also produces odor.

At present, the most commonly used antioxidants for oils and their products are BHA, BHT, PG, TBHQ, and tocopherols. As for vegetable oils, their antioxidant capacity is in the order of TBHQ>PG>BHT>BHA. As for animal fats, the order of their antioxidant capacity is TBHQ>PG>BHA>BHT. For anhydrous milk fat, their antioxidant capacity is in the order of PG>TBHQ>BHA>tocopherols.

Pastry and bread stored in the air for a long time are prone to spoilage due to oxidation of their lipid components. The oxidation of oil components not only causes food discoloration, discoloration, destruction of vitamin A, D, E, and other components, but also produces odor. In addition, essential fatty acids such as linoleic acid and linolenic acid in oil are also damaged, reducing the nutritional function of the product. In severe cases, harmful substances such as oxides, peroxides, and decomposition products such as epoxypropylaldehyde can be produced, leading to food poisoning.

In summary, pastry food undergoes complex production processes, greatly reducing the stability of oil and increasing the risk of product storage, sales, and circulation. However, the currently allowed antioxidants cannot meet the technical requirements for anti oxidation of all pastry food.

With the development of the food industry, the forms of pastry food have become diverse. The various oils and fats used in pastry are essential ingredients. Oil, with its good crispness and unique flavor, has become one of the three major ingredients in baked goods. It plays an irreplaceable role in the production process of pastry food and is also an important source of energy for consumers. However, the oxidation and rancidity of fats and oils, as well as the production of unpleasant flavors, are a problem that troubles many pastry food producers.

 In the study, it was also found that the antioxidant effect of TBHQ is 5-7 times that of other antioxidants, because their stability is different after reacting with peroxides. In addition, TBHQ also has characteristics such as high temperature resistance, oil solubility, and antibacterial properties, which are widely used in edible oils, fried foods, etc.
